In fact, Xu Qing is not interested in things like light bombs now. What he cares about is the person who came out of the strange wall, the person who looked exactly like him as General Geng said. He remembers that he was attacked by the strange wall just now.

The transparent dog's attack was only one step away from the wall. If someone really walked by him, it would be impossible to miss it. Could it be that that guy grew out of the wall?

At this moment, Professor Cai had poured out the transparent dog from the sky-catching net and dragged it to the wall by its paws. Although this thing was dead, it still had strong research value. For him

A biologist would not easily let go of such a good specimen.

Xu Qing put away the sky-catching net and scanned the strange wall opposite with his kinetic clairvoyance eyes. To his disappointment, he found no useful clues at all. This wall was like a projection of a virtual image and did not actually exist.

, but ordinary people will not bang their heads against the wall easily. Even if they go in, they will still face the fatal attack of the transparent dog.

General Geng glanced at Xu Qing, who was staring at the strange wall in a daze. He already guessed what the boy was thinking. He took two steps forward, reached out and patted his shoulder and whispered: "Go in and throw two light bombs first. Let's go in."

Come in in about half a minute, don't worry, guys who look exactly like you will appear again, and you will definitely be able to figure things out by then." The old general meant to let him enter the strange wall again, and at the same time, he also gave him

A hope that someone just like him will appear again.

Xu Qing nodded, reached out and took off two button-like light bombs from the leather around his waist, and asked in a low voice: "I have never used this thing before. I don't know how to use it?"

General Geng smiled and said: "The method of use is very simple. Just throw it out and drop it on the ground. Even if there is a layer of sponge on the ground, it will still explode. For humans who have been exposed to the sun all year round, the light bomb has no side effects. It is only quite harmful to the sun."

Meet the sun."

Xu Qing nodded, turned around and walked into the mysterious strange wall again. The moment he passed through the wall, there was a soft sound in his ears. The source of the sound was right above his head. These transparent dogs seemed to be interested in him.

As if he was a little afraid, he actually didn't launch an attack for a long time. The location he was in was another underground palace. Both the layout and decoration were similar to the one outside the wall. The only difference was that there was a crisis here.

Whoosh - two light bombs flew out of the palm, drawing two bright silver arcs in the air and landing deep in the underground palace. Two blazing lights lit up instantly, as if to break through the darkness.

The light group expands rapidly, and time cannot describe its expansion speed. In the blink of an eye, the entire underground palace is illuminated by the light group as bright as day, and everything hidden in the darkness will be invisible.

Chirp! Chirp! Waves of screams echoed in the underground palace, and then there was a thumping sound in my ears. This was not a drum, but a panicked transparent dog falling from the ceiling and falling heavily to the ground.

, they are indeed afraid of sunlight and temperature as General Geng suspected.

Half a minute passed very quickly. Before the effect of the light bomb completely disappeared, people from outside the wall had already rushed in. The soldiers surrounded General Geng and several scientists with a tacit understanding. They all put on a pair of sunglasses and held the

The guns were pointed at all directions in the underground palace.

Click, click, click - the muzzle spit out tongues of flame, almost negligible in the bright white light. The high-speed rotating bullets shot everywhere with extremely strong penetrating power, accurately hitting those struggling on the ground.

Transparent dogs, these animals huddled on the ground emit traces of green smoke under the light emitted by the light bombs. This is the most identifiable feature. It is not difficult for well-trained soldiers to shoot them. They lose their

Transparent dogs with mobility capabilities are stationary targets on the shooting range, and it is zero difficulty to shoot them.

Human intelligence is often directly proportional to their destructive capabilities. Although these transparent creatures are ferocious, they only live in this limited dark area after all. They are no longer able to stop the pace of human exploration. Death may be their final destination.

.

The gunfire stopped, and the underground palace once again returned to a predominantly dark tone. All transparent creatures had been shot and killed. The soldiers lowered their steel guns with a look of indifference on their faces.

Xu Qing saw a row of huge square stone pillars in the center of the underground palace. They were the same as the stone pillars in the underground palace outside the wall. The only difference was that there was a dark round pillar in the gap between the stone pillars. If you didn't look carefully, you would never see it.

I found that there were several irregular small pits where it was grounded.

The two light bombs successfully eliminated all the transparent creatures in the underground palace. Geng Yunpeng led six scientists quickly towards the row of stone pillars in the center of the underground palace. They were all experienced scientific research experts, so they could naturally see at a glance the most valuable research objects here.

Except for the row of stone pillars, they were the corpses of transparent creatures scattered everywhere. Perhaps the stone pillars were more valuable in their eyes.

Xu Qing followed closely beside the old general, but his attention was focused on the black cylindrical foot. He found that the small hole at the foot seemed to be deliberately left for embedding something of the same size. He was slightly curious.

I scanned the surface of the pillar with my clairvoyant eyes, but the result was quite unexpected.

The proud clairvoyant eyes couldn't see through this black pillar. I didn't know what kind of special material this thing was made of. Xu Qing couldn't help being curious and started to reach out to touch the surface of the pillar. This pillar was different from the squares on both sides.

The stone pillars are too disparate in comparison, just like a disharmonious sapling growing in the middle of a row of towering giant trees, but no one will ignore its existence because it is special.

Not only Xu Qing noticed this black pillar, but also Dr. Zou who was holding a compass. He also discovered a very strange thing. The magnetic needle arrow on the compass was always pointing at this black pillar, no matter how the direction was changed.

, in confusion, he took out a small piece of magnet and stuck it on the pillar.

The magnet was not adsorbed on the surface of the black pillar. The moment Dr. Zou released his palm, it slid down. He took out a small hammer and struck it on the surface of the pillar without giving up. It only made a dull sound. The pillar seemed to have no energy.

It's not metal, because it should be some kind of stone with a very hard texture. No matter how hard Fatty Zou hits it, not a single fragment will fall off, which is even more strange.

Xu Qing touched the surface of the black pillar with his palm, touching it from top to bottom. He seemed to like this feeling very much. The black pillar in front of him looked ordinary on the surface, but after touching it a few times, it would make people feel a strange feeling.

With a feeling of peace of mind, a strange thought suddenly flashed through his mind. Try to input Zhengyang Qi into it. The Qi moved with the thought, and a pure and hot Zhengyang Qi flowed down the palm to the black pillar. Maybe it was just
