Although Ivana had Lynn's letter of recommendation, she had also gone through selection and ability assessment.

When undergoing the combat power test, Ivana "killed" three formal wizards who joined forces. Such combat power is considered outstanding even among the three-ring shaping wizards who are proficient in close combat.

They also need a power that specializes in the physical body, so that if their spellcasting is disturbed during exploration, they will not be helpless.

Seeing Raphael say this, Lin En said no more. Since this was Ivana's own choice, he couldn't interfere. He turned to look at the space-time gate that was constantly surging and asked.

"Have you tested it? Is there an upper limit to its expansion range? What kind of matter can it accommodate in and out? Where does the energy that sustains it come from?"

Lynn’s questions are undoubtedly many and critical.

Vittorio naturally did not waste these few days, as he had already conducted preliminary experiments. The first one was the expansion of the space-time gate. He predicted that there should be no upper limit, or the upper limit was very, very large, but the consumption of magic power would also increase synchronously.

Vittorio once expanded the diameter of the space-time gate to more than 50 meters, but it still did not reach the limit. He was worried that further expansion might cause some adverse effects, such as causing the space-time gate to be discovered by the opposite side, so he did not continue trying.

"In addition, we have also tested the difference in the speed of time between the two worlds." At this point, Vittorio glanced at Sean, who seemed a little depressed. "This is all thanks to Sir Sean for developing the quartz clock!"

In front of Lin En, Sean didn't dare to accept the title of developer, and said with a wry smile, "It's not a research and development. Speaker Lin En has already explained the principle of the quartz clock very clearly."

"I just provided a design idea. After all, the quartz clock was made in your hands. It only took six days. That's great!" Lynn comforted Sean and affirmed his efforts. Then he continued to ask Vittorio whether he had sent people into the space-time gate in advance and how the speed of time was calculated.

"No, we haven't sent anyone in yet, we just used some tricks." Vittorio explained with a smile.

Since this space-time gate can allow people to enter and exit, objects should be able to enter and exit as well, so they tried tying an object with a rope and throwing it to the other side of the space-time gate, and then tried to see if they could pull it back.

The result is undoubtedly...

Failed!

The rope that was pulled back was broken. After several experiments, they analyzed that all objects entering the space-time gate need to withstand a tearing force, just like being sucked into a whirlpool in the sea.

So Vittorio had the rope replaced with a stronger steel cable, and tied a heavy object to the other end, which was thrown over at high speed and then pulled back quickly.

This time the experiment went on smoothly without any accidents. Then, a quartz clock was added to the heavy object, placed at the other end of the space-time gate for a while, and then brought back. Based on the time difference between the two quartz clocks, the flow rate multiplier could be easily calculated.

Lin En nodded. This was a good idea.

"According to our calculations, the difference in the speed of time flow between the two worlds is approximately 7.25 times, but this difference is slowly decreasing. According to the current rate, the speed of time flow of both sides will be completely unified in about 450 years..." Vittorio kept explaining.

Since the slowdown in the difference was very slight, in order to measure it, they conducted hundreds of experiments and spent a whole day. They also used a quartz clock that could be accurate to tens of thousandths of a second to integrate the values ​​of hundreds of tests together, list equations and calculate, and finally they could barely work out a corresponding value.

We have to wait for Raphael and others to return to confirm the details. If the value calculated by his time velocity decay equation is completely consistent, then it can be explained.

"Four hundred and fifty years? It seems we have plenty of time." Raphael raised his eyebrows. The seven times difference in the speed of time flow was undoubtedly terrifying. This meant that seven years passed on their side while only one year passed on the other side's side.

Vittorio poured cold water on him. "Based on the current rate, I guess the more intense the surge of magic power, the faster the difference in the speed of time will decrease."

In other words, if the space-time gate is controlled by the other party and is expanded to increase the speed at which magic power flows into this continent, the difference in the speed of time flow between the two worlds will be further reduced, and their time advantage will no longer be so obvious.

"In short, your mission this time is very difficult. You need to collect as much information as possible about the other world. It would be best if you can confirm whether the information given by the Star Messenger is correct. You should also try to avoid contact with the enemy..."

Vittorio spoke solemnly, and then handed a fist-sized strange sphere to Raphael. "I think you have seen this thing and know its power, right?"

Of course Raphael recognized what it was. Back in the Kerosene City, Lin En had used something similar to cast [Skyfall] to cleanse the radiation spreading across the Land of Death. The aftermath alone almost flattened the Kerosene City.

Faced with such a powerful weapon, Raphael's wrist trembled slightly when he took it, for fear that it would be activated by accident.

Vittorio repeated the method and reminded, "Don't use it unless it's absolutely necessary."

Raphael rolled his eyes. With the terrifying damage radius of [Skyfall], this thing could probably only be used when both sides were to perish.

The main theme is heroism!

“By the way, you can also take this ring with you.” Lin En took out a special mystical ring.

"What does it do?" Raphael asked curiously.

"It's just an experiment. It may not be useful." Lynn said casually without any intention of revealing anything.

After hearing what Lin En said so mysteriously, Vittorio took a few glances at it, and then he found that this dark gold ring was very familiar in color and texture.

"This should be the metal material used to make the Corona Medal, right?" Vittorio asked in surprise.

“Yes, I melted a Corona Medal and used part of the material to make this ring!” Lynn nodded in acknowledgement.

You melted the Corona Medal? When these words came out, the wizards present all widened their eyes, and Raphael's wrist holding the ring also trembled.

The Corona Medal is the highest honor in the magic world. This magic star is willing to melt such a precious thing, which is simply a waste of resources!

Lin En didn't care much about it. He asked Harov. This strange metal came from outside the space-time gate. They only got 12 kilograms in total. Because it was rare and had strong energy carrying capacity, it was divided into 12 Corona Medals.

There are only two rings left in the parliament, and they have to be kept to give to others. He happened to have some extra ones, so he simply melted one and used it for research and experiments. This ring is one of his achievements.

Chapter 526: No matter how bad the environment is, life will always find a way out!

Although Raphael didn't know what Lin En was doing, he still took the [Ring of Mysticism] out of trust.

Yolande, Tik, Ivina and others also took their instruments and prepared for the trip.

Lin En did not give a long speech to boost morale, but instead told them to be careful and cautious. Safety and secrecy were the most important thing for this exploration. At worst, they could retreat and rest while the council prepared a second team to go in for the exploration.

"We will pay attention, see you later!" Raphael said solemnly, and then took the lead to step into the surging time and space gate, and the others hurriedly followed.

"Sure enough, it's been cut off?" Watching several people disappear into the time and space gate, Lin En sensed it and thought secretly.

However, this was also within his expectations, he just didn't know whether the soul-splitting magic could work on the other side.

……

On the other side, Raphael, who stepped into the space-time gate, felt dizzy, as if his consciousness was stripped away and his body was stuffed into a whirlpool and spun dozens of times.

When Raphael came to his senses, he had already appeared at the other end of the space-time gate.

"Such a strong magic."

This was Raphael's first feeling. He didn't know if it was because of the space-time gate, but the magic content nearby was almost comparable to the magic tide on Sundays every year.

Beside him, Yolande, Tik, Ivina and others also walked out of the vortex of time and space, and saw a dark, cold and desolate world.

Just as the intelligence said, the temperature here was extremely low. Tik couldn't help but shiver. He took out the temperature detection device and let it sit for a while, and soon came to a conclusion.

"The temperature here is around minus twenty degrees Celsius." Tik said in amazement.

"No wonder it's so cold." Yolande also shrank his neck. Even though he had cast anti-cold magic on his wizard robe in advance, he was still freezing.

"Also, the gravity in this world seems to be lighter." Ivina tried to jump and suddenly jumped three or four meters high.

Although her physical fitness was very good, she had never been able to jump to such an exaggerated height without the help of magic and divine arts.

With Ivina's reminder, Raphael and others also noticed this and their bodies did feel a little light.

"According to the theory of universal gravitation proposed by Speaker Linn, the mass of this world should be much smaller than that of our planet." Yolande, who specializes in astronomy, looked up at the sky.

There are no stars, moon or sun here, just darkness.

"Now is not the time to think about these things. Let's find a place to settle down and do an experiment on gravitational acceleration and we'll know." Raphael drew everyone's attention away from the exploration of gravity and temperature.

In fact, this is also one of their missions this time, to explore the composition of the elements and the gravitational constant of this world, and they have brought the relevant instruments.

If conditions permit, the parliament would like them to use Lynn's light difference method to estimate the area of ​​the continent or planet, but Raphael felt that those parliamentarians had a complete problem with their brains, as there was not even any light in this place.

If one wants to create a large enough light source, one has to release [Skyfall] directly in the sky, but that would be like exposing one's whereabouts...

"As bright as day." Raphael raised his hand and cast a spell. A flashing ball of thunder condensed above everyone's heads. The continuously emitted fluorescent light immediately dispelled the deep darkness nearby.

Only then did everyone realize that the space-time gate here was also erected in a valley. Probably because the church's expeditionary force had slaughtered nearby monsters not long ago, the air was filled with a bloody and foul smell.

"Very good, the magic can be performed smoothly." Raphael breathed a sigh of relief. The thing he was most worried about did not happen. He suddenly felt more confident and then turned his gaze to the psychic wizard Tika in the team.

Tika nodded and opened his large wizard robe.

Ivana's pupils shrank slightly, because the other wizard's robe was filled with half-palm-sized, pitch-black bats.

"Is it a demon bat?" Several wizards recognized it immediately. It is a kind of weak magical beast that likes to suck blood. However, it usually moves in groups. Without the help of wizards or diviners, a hundred demon bats can massacre an entire town.

However, this psychic wizard brought the magic bats here specifically, obviously not to let them fight.

This kind of magical beast can use echo waves for positioning, and is undoubtedly an excellent reconnaissance assistant in the dark environment of foreign lands, reducing the possibility of being exposed.

Yolande on the side also took action and put his hands on the ground.

He was chosen to join this exploration team not only because of his knowledge of astronomy, but more importantly, he also had the ability to sense ground vibrations.

In an unknown world, the more investigative means the better, otherwise there might be some oversights.

For example now...

Yolande's expression suddenly changed as he touched the ground. He suddenly shouted in shock. "Underground...Underground!"

At the same time, a warning sign surged in Ivana's mind, and then the solid ground under her feet suddenly collapsed. A huge mouth full of fangs emerged from the ground and bit towards her, with cruel and murderous gleams in its blood-red eyes.

Ivana had already jumped high into the air. Facing the huge mouth of the abyss, the girl's expression remained unchanged. She drew out the slender blade at her waist and stabbed it into the opponent's bloodshot eyes with incredible precision.

Hot blood and green juice spurted out together, and after falling to the ground, they were frozen into pieces of tiny ice crystals, along with roars of pain and anger. The two-meter-thick body swung wildly, plowing grooves in the solid ground like a drill.

Ivana used the reaction force of the other party's swinging body to pull out the blade and retreat to a safe area.

However, there was more than one giant worm that attacked them. An unlucky wizard was also targeted. However, he obviously did not have Ivana's excellent reaction speed, and was swallowed up by the giant worm that drilled out of the ground.

"Damn it!" Raphael's face was extremely ugly, and he cursed angrily. The flashing lightning ball above his head immediately shrank into a ball, and then a strong laser beam flew out, cutting off the body of the worm that drilled out from the ground!

The worm's huge body fell to the ground, but it was still twisting violently, raising a cloud of dust.

Tik and others immediately rushed up, trapped it with magic, cut open the body of the giant worm, and rescued the unfortunate wizard.

Thanks to the fact that the wizard was swallowed in one gulp, he was not bitten into pieces by the worm's fangs. In addition, he was rescued in time, so he was not seriously injured. His body was just covered with green body fluids.

Seeing that the other party was not seriously injured, Raphael finally breathed a sigh of relief. If there were casualties as soon as they entered the foreign land, or if the other party was seriously injured and needed to be sent back, it would be a great embarrassment for him.

On the other side, Ivana also cooperated with Yolande and others to kill the worm that attacked her, and removed some limbs and blood of the [Sand Worm] and sealed them for research.

"This should be the [Sand Worm] mentioned in the intelligence. I didn't expect that this thing's actions would be so secretive." Raphael said in a serious tone.

He originally thought that something this large would have some signs even if it was moving underground, but it turned out that even he himself was unable to detect any signs.

"No, I think they have been waiting here to hunt." Yolande explained. Just now when he cast the detection magic, he found that the two worms had been hiding underground.

"It's really insidious. It has actually learned to wait in front of the gate of time and space, waiting for others to come in." Tik said with a palpitating heart as he looked at the dead [Sand Worm] that was dismembered. If it was him who was targeted just now, he would not be sure that he could escape.

Tik even suspected that these giant worms had the ability to distinguish the strength of their prey, because the best time to attack should be when they just came out of the space-time gate, but the other party did not take action.

Perhaps because the first person to step in was Raphael, the Sand Worm did not have the ability to kill him, so it remained silent until it sensed the slight vibration caused by Yolande's detection magic. It realized that it had been discovered and suddenly launched an attack.

"In any case, we must be more careful next time." Raphael was extremely alert, then looked at the psychic wizard Tika and asked about the situation of the magic bat's investigation.
