Then he raised his head, and he noticed something, there was a huge crack in the rock wall he climbed, this crack was not obvious from below, but when he climbed on it, he found that this crack was quite amazing, obliquely thirty or forty meters away, almost tearing this rock wall apart.

The key is that when Lin is climbing, his fingers must inevitably pick at any reliable cracks, and after his fingers have reached into this crack for about five or six centimeters, what they touched is a completely different texture, at least distinct from the touch of the rock, hard, rough, but with a peculiar temperature, it is like human body temperature! But no one's body temperature is high.

"What is this?" Lin couldn't help but be a little curious. "Wood, fossils, rubber, no, no, no, neither. ”

His curiosity was aroused at this point, and there happened to be a raised stone next to him that could be used as a platform, so he quickly climbed over and stood on the platform, intending to take a break on the one hand, and on the other hand, intending to thoroughly investigate the truth and see what kind of secrets were hidden in this huge rift.

According to Lin's strength at this time, this huge crack in front of him must not be difficult for him, he took out a long pen made of hard steel, and after using it as a chisel, he chiseled the crack in front of him little by little, in this way, the crack in the rock in front of him quickly became wide, and he could no longer only reach into his fingers, but could extend his entire palm into it.

Immediately afterward, Lin took out something from this huge crack! He looked closely, and it was half a broken claw! This claw was about half a meter long, showing a yellow and red color, and the fracture was torn, but it exuded a kind of majesty, like a crown with natural powerful attributes.

Lin frowned and looked at the broken claw, then turned his head to look at the towering mountain wall in front of him, and the crack in the rock that was dragged down like a wound, combined with the half of the claw remaining in the crack, he began to gradually make up a scene that was shocking to the point of suffocation......

In this vast subterranean space, a fierce deathmatch is taking place between two enemies capable of aerial combat, one of whom is supposed to be a dragon and has the blood of a red dragon (the broken claws are still inferred with warmth).

Suddenly, the dragon suffered a heavy blow, let out a terrible wail, hot blood spilled from the air, and it could no longer maintain the majestic posture of soaring in the air, swirling and sliding crookedly, flapping its wings unwillingly and violently.

At this time, it was attacked again, and its entire body fell down like a burning meteor, sweeping diagonally over this towering mountain wall, its wings were still fluttering instinctively, at this time, the dragon claws on its wings crossed the mountain wall, and the hard stone wall was quickly torn out of a long crack under the grasp of the dragon claws, but when it finally fell, half of the dragon claws were also broken in it because of the huge force, but for this giant beast, such injuries were completely not worth mentioning, because the fire of its life was about to be extinguished。

Following the direction of the rift, Lin narrowed his eyes slightly, and then looked in that direction, but all he saw was deep darkness, but he knew very well that if he guessed correctly, then he would find the remains of a dragon there.......

Just a little hesitation, Lin decisively climbed in that direction, it can be said that it is very difficult for ordinary people to do this, but for professional Lin, as long as he spares his physical strength, then it is not so difficult.

For this matter, Lin not only wanted to prove whether his inference was correct, but because he was already well aware of the danger in Yuelun Mountain at this time, so if he could find more clues, and then wipe away the dust of history and get more truths, it would be worth it, because he was not in a hurry.

However, in this dark underground rift, even if there is a general direction and goal, it is definitely not easy to find the remains, Lin also spent a lot of time in the future, and a few times even caught loose stones in the process of climbing and was in danger, if he was an ordinary person, even a professional with a slightly inferior strength, he would be seriously injured or buried here......

Finally, under a stone cliff in the shape of an L, the panting Lin finally saw what he was looking for under the light of the torch, and when everything in front of him met Lin's eyes, he was shocked all of a sudden, and he was stunned for several minutes before coming back to his senses:

"How...... How could this be!!"

"Now we're on the Imperial Proving Ground. ”

Holmes looked at the dirt under his feet and shouted at the group.

After being verbally beaten by Du Yuqi, Holmes became a lot more active, and began to be conscientious along the way, which can be regarded as playing the role of half a guide.

At this time, she pointed to the dirt and explained:

"In the beginning, the Bilmark Imperial Proving Ground was clearly enclosed with a wall, and the rest of the people were not allowed to enter and leave at will, but later as this place was abandoned, there happened to be a large amount of metal materials in the wall that built this place, so it was quickly stolen and dismantled. ”

"At the same time, the creatures in the Bilmark Imperial Proving Ground have obvious differences from the original race, so according to the original design, their living environment, edible plants, and even water sources, and soil have been artificially modified, adding some special elements, at this time, this purple-red soil, even in the entire Arad continent, is extremely rare, so as long as you see this iconic soil color, it means that you have come to the Imperial Proving Ground. ”

Since they came to the Imperial Test Ground, and witnessed the fierce battle last night, they all raised their attention, which can be said to be extra careful, and after continuing to walk in for a few kilometers, they could immediately feel that although the test site was still those plants in the depths of Luolan, the color was obviously dark, and many plants became huge, many vines were staggered and coiled, like giant pythons, and some trees just stood there alone, giving people the feeling of covering the sky and the sun, as if they were a forest alone.

At the same time, the creatures in it seem to have a very strong aggressiveness, Du Yuqi just went to urinate next to him, and found that a gray praying mantis jumped up to hunt a butterfly, under normal circumstances, the praying mantis must have successfully caught the butterfly and killed it, but what happened next made Du Yuqi stunned, the butterfly spread its wings, and then dodged the mantis's pounce, but it did not fly far and stopped, and then the praying mantis continued to pounce, and the butterfly continued to fly away......

Seeing all this, Du Yuqi felt a little puzzled, why? Because the insect kingdom is actually very weak, all their activities will follow two cores, survival and reproduction, and for this butterfly, it is meaningless for it to keep repeating this teasing move, because the praying mantis can fail many times and only need to succeed once, but this butterfly cannot fail once!

However, the confusion in Du Yuqi's heart was quickly answered, and when the mantis pounced for the fourth time, it failed as always, but when it landed next, it staggered, and then fell to the ground and trembled, looking as if it had suffered a heavy blow.

At this time, Jett didn't know when he had already walked over, and looked at this scene with some surprise and said:

"Could this be the legendary eagle butterfly? It's a rare carnivorous butterfly that depends entirely on hunting the rest of the insects to survive! ”

Du Yuqi was stunned for a moment and said:

"Why are you here?"

Jett said:

"You see you haven't moved for too long, so let me see what's going on. ”

Du Yuqi said:

"You're familiar with the wild world, let's talk about how this praying mantis was plotted. ”

Jett said:

"I think it should be the poisonous powder on the butterfly's wings, when it takes off, it will deliberately violently shake the wings, so the poisonous powder on the wings is emitted, and the praying mantis that flutters inhales it, and the amount of poisonous powder inhaled at the beginning is small, so it will not cause too serious consequences, but after a few more times, the toxins accumulate to a certain extent, and naturally the mantis that is a hunter becomes the prey. ”
