After making the decision, everyone closed their eyes and took a nap, taking the time to rest and recover. Du Yuqi took this opportunity to treat the burns on his body. After about ten minutes, Du Yuqi suddenly felt uneasy. He sat up straight and looked around suspiciously, while the rest of the people did not seem to have any abnormalities.

Just when Du Yuqi thought he was being a little overly nervous, he suddenly felt a huge earthquake. The earthquake was not particularly strong, so Du Yuqi immediately looked at the mineral water bottle on the stone next to him. Sure enough, he found that the water in the transparent mineral water bottle was making ripples.

"Is this an earthquake?" Du Yuqi was pondering. Suddenly, he saw a thick black gas rising from the sky in the distance, rushing straight into the sky, and then immediately turned into a purple-black giant palm illusion, slapping fiercely towards the bottom.

The illusion of a giant hand has only three fingers, with sharp claws and very thick bone joints. It is obvious at first glance that it is not a human claw but a demon's claw, and many details are so lifelike that it can be said that there is no difference from a real giant hand.

Although Du Yuqi didn't know what this move was, it was filled with extremely strong demonic power. It was obviously a skill used by Neilbas, and its power must be amazing. It was unknown what happened to this guy that caused him to start a war, but his enemy should not be simple either, most likely a being at the level of the Mechanical Bull King.

Just after this fierce conflict, another muffled roar like thunder was heard in the distance. The roar did not sound loud at first, but it was extremely deep, as if there was a buzzing resonance in the chest, which made people so sad that they almost wanted to spit out blood to feel better.

Then, not long after the muffled roar, a series of bright lights flashed from the horizon, like lightning or bright lights. Although it only flashed for a moment, it remained deeply in people's memory. Then, a straight ray of light suddenly appeared from the central area of ​​the Bilmark Empire test site, like a Tower of Babel made up of bright lights, rushing straight into the sky!

After the bright light shone, Du Yuqi and his companions were still a little confused. Then they felt that the underground began to shake violently, and there was a buzzing sound. The shaking was very regular. Then the building in the center of the ruins began to collapse, and a deep hole of about five or six square meters appeared. A ray of light suddenly shot out from it and shot up into the sky, as if echoing the ray of light shot out from the center!

Not only that, at this moment, everyone looked far away and found that there were eleven similar lights rising in the entire Bilmark Empire test site! At this moment, the Bilmark Empire test site, which had been silent for hundreds of years, seemed to be lively again, returning to the heyday when the empire used the whole country's strength to build this place.

"It seems...it seems that something extraordinary has happened!" Even Holmes was shocked at this time.

The buzzing sound coming from underground never stopped. When Du Yuqi heard the buzzing sound, he had an illusion of being upset, as if something bad was about to happen.

He hesitated for a moment and wanted to ask everyone to evacuate first, but after looking at Duize who frowned tightly, he swallowed the words that were on the tip of his tongue. Because Du Yuqi could understand Duize's mood at this time very well. No matter who it was, the feeling of failure at the edge of success would never be a good feeling.

At this moment, they suddenly heard Meimei shouting inside. Everyone thought something had happened to her, so they rushed over to take a look and found that she was standing in front of the short-range teleportation array with an ugly look on her face.

"Everyone come quickly, there's something wrong with this teleportation array!"

At this time, everyone looked towards the short-range teleportation array that could teleport to the modulation laboratory, and found that the lines of the magic array outlined on it began to shine and emit bursts of red light, as if giving a warning, and the crystals embedded in the short-range teleportation array also looked dim, as if they would turn to ashes in the next second.

Every time he half-knelt on the ground, he took out a strange instrument to test it, and finally came to a very straightforward conclusion:

"I don't know what happened at this time, but to put it simply, there should be a large-scale energy leakage, so this short-range teleportation array has suffered very serious irreversible damage. I estimate that it can only be used five times at most!"

Du Yuqi frowned and said:

"At most five times? That means there is still a chance of an accident. How many times do you think you can ensure safe entry and exit?"

After taking some measurements, he said simply:

"Four times. There will be absolutely no problem if the transmission is within four times."

Du Yuqi frowned and said:

"We can't just rush in like this. We have to use one time to teleport a summoned creature in first. This way, we can test whether the Crazy Ivans are guarding near the teleportation array. In this way, there are only three times left. Teleporting in once, but teleporting out also counts as one! So one person will waste two places, so only one person can go in. If two people go in, then the remaining person can only go in. If he wants to get out, he will have to rely on luck..."

At this time, Duize suddenly stood up and said coldly:

"Don't think about it. I'm going to go and try my luck that time."

Du Yuqi shook his head and said:

"You are not suitable. The terrain below is complex and narrow. It is not a place where a sharpshooter can exert his maximum combat power. The most suitable person to go is me, because after I go in, I can consume Holy Crown to summon Jet to my side. In this way, the actual combat power is doubled, and my various abilities are more suitable for fighting in such a closed space. After the battle, I will teleport out and consume Holy Crown to summon Jet!"

After hearing what Du Yuqi said, Xi said coldly:

"You just suffered a great loss at the hands of Crazy Ivan, okay? I'm going in!"

Du Yuqi blushed and said:

"That's because I don't know how they attack, okay? Now that I know, I won't give them a chance! At most, I'll just get some superficial burns."

What Du Yuqi said was not wrong. His physical fitness at this moment was much stronger than that of ordinary people. Even if an ordinary person held his breath, he could continue fighting for more than 20 seconds. If he was trained, this time could be extended to more than one minute.

If Du Yuqi is well prepared, there is no problem for him to fight while holding his breath for five minutes. As long as he does not suffer internal injuries such as respiratory burns, the external burns will not have a big impact on his fighting ability.

After the two of them argued for a few words, Xi shut her mouth and stopped talking, but she looked very angry.

Du Yuqi had no time to coax her at this time. Seeing that the buzzing sound underground was getting stronger and stronger, and knowing that time was running out, she hurried to the teleportation array and asked Holmes to send a mechanical Hedel in. Three minutes later, she confirmed with Holmes that the mechanical Hedel had not terminated the contract with her and was therefore not dead. So Du Yuqi made preparations and decisively stepped into this short-range teleportation array and re-entered the laboratory on the second underground floor.

When Du Yuqi was teleported in, he was ready for a fight. He held the Bone of Hess in his left hand, ready to block at any time, and held the Mind-Splitting Blade in front of him in his right hand. However, after he was teleported in, he found that his worries were unnecessary. It was still not much different from when he left. It was very quiet, but there were red police lights on the wall. There seemed to be some vague electronic sounds coming from afar, repeating something over and over.

The mechanical Hedel summoned by Holmes before was patrolling in the hall following her instructions. When he saw Du Yuqi entering, his pointed ears pricked up and he raised the iron rod in his hand. He lowered his guard only after he realized that it was a friendly army.

But at this time, Du Yuqi suddenly noticed that there was a shining light on the teleportation array, and the lines outlined on it began to become blurred, and it seemed that they would soon disappear. Then a figure suddenly appeared on it, and it was none other than Xi!
