Cassia and the others flipped through the shell and checked it several times, carefully avoiding the shaking gunpowder, and even wrapped the cement-like gunpowder with snow. Although they knew that there would be no accident, the people around were always not relieved.

"It's just a shell that has been buried for a long time." The two captains were a little disappointed. They thought they had discovered something useful. "Please continue to look around. The heavy snow may have buried everything. Especially on these ancient trees, take a closer look at whether there are any traces of similar craters."

After hearing this, the other soldiers continued to spread out around them, further expanding the scope of their search.

"It seems that we are really the first team to arrive here." One of the captains looked around and said surely.

"It should be like this." Another captain agreed at this time, and there was no obvious clue around him. Apart from the endless snow, there were only ancient trees that stood tall.

Cassia stood aside and listened, but did not respond to a word. In the strange eyes of the two captains, he took out a strong flashlight from his backpack, probably adjusting the power to medium, and the beam shot out, and the small snow was illuminated a little in an instant. The woods had now become a little dim.

"What's wrong? Is there something wrong with the shell?" The two captains also looked over. There seemed to be no change under the light. They just formed into pieces, with a little wet red rust, and their color looked a little brighter.

"There is no problem with the shells." Cassia replied, and the strong light flashlight hit his feet, "but there seems to be some problems under this soil."

"Look at it, it's not completely solid soil. There is a big hollow area underneath." Cassia was a little uncertain. The rusty shell just now pulled out of the soil and formed a hole about two adult waist-sized holes on the ground. Now Cassia turned on the flashlight and the light shone directly into the hole, without touching the bottom, and it seemed a bit deep below.

"This is the only thing that happens here?" Cassia spoke, swaying the flashlight slightly. Under the bright light, you can see another scene underground by pulling out the holes formed by the shells.

There is indeed a hollow area in the soil under their feet. Under the light, you can clearly see the dense tree roots hanging down, with varying thickness, as if a waterfall formed by tree roots. I haven't seen the sun for a long time, and the skin of the tree roots is tender yellow.

On a plate of tree roots, Cassia and the others saw no mold, but some fluorescent mosses existed.

"The air below seems to be dry all the time." Cassia judged at this time. Then, two flashlights were added to the corner of his eyes. The two captains seemed to be interested in the hollow area under their feet. They each took out their own strong flashlights to see what was underneath.

The dark space was illuminated by three beams of flashlights. Many trees were roots, which were the most intuitive impression of Cassia and the other three. In the light, under their sharp sight, other things were soon discovered. They were equally large copper tubes. When Cassia saw those copper tubes, they saw their function through the color and the thickness of the tube walls.

"There are all pipes for steam transport, and they are all classic designs and standardized models that the empire has been using until now. It has been almost a hundred years, but until now, this classic design and standard, as well as material processing, is still applicable to all aspects of steam power." Cassia explained to the two captains at this time, "Looking at how twisted they are by the roots, I think the actual history of the things that are left behind is much older than the big trees that grow on them."

The two captains opened their eyes wide at this time, and the beam of the flashlight slowly spread out along the tree roots towards the surroundings. They looked at other things in the underground space bit by bit.

But the hole formed by pulling out the shells seems a bit small at this time. It seems impossible to keep all the scenes in the dark space below in your eyes and not expand the hole.

Cassia asked the two captains to help him get the flashlight. There was no easy-to-use tool around him, so he used his hands to pull out the soil piece by piece. In the cold weather, the soil almost frozen into ice, lost its flexibility, and became extremely brittle, which made Cassia's work to expand the hole.

But Cassia and the other two captains both ignored a significant matter at this time, perhaps because they had not examined other matters now and focused on the underground cavity.

They remembered that they were the surgeon, but at this time they completely forgot their weight. Especially Cassia, as an obese person among the surgeons, his weight was even much heavier than the two captains.

When he pulled away the hard mud under his feet one by one, a crisp "click" sound suddenly sounded from the feet of the three of them. Cassia immediately realized that he knew what was going on. The mud under his feet should not be able to withstand their weight and reached the critical point of collapse.

"You can't use too much force at this time, otherwise it will only accelerate the collapse of this place." Cassia considered this and found that he was thinking too much. At this time, several huge cracks were cracked open on the ground in a small area. He only felt that his body became very light, and then he quickly fell down below.

Cassia immediately spread her arms, grabbed the ground that had not yet collapsed on both sides, preventing herself from falling. However, after a chain reaction, Cassia's palm rested on the ground on both sides, and it was immediately covered with dense cracks, and then it turned into a fragmented shape like glass.

His body irresistibly fell to the height of most adults. Just as Cassia was judging how deep he was and how to land to reduce damage, he felt that his shoulders were tightly grasped by a wide palm.

They were two captains, and their reaction was equally amazing. At this time, they reached out and grabbed Cassia, ready to pull him out of the cracked hole.

"You should reduce the weight of your body." The two captains felt Cassia's amazing weight when they started. While pulling him up, they said, "Look at your body dry and thin, but I didn't expect that there would be such a weight that would not fit the body shape."

Cassia smiled helplessly. Her body had just undergone a major blood change, and her weight had decreased a lot at this time. At the full state, his weight was a little heavier than at this time.
