Five people climbed around the wall, and the five of them were very far from each other, and it looked like five people had surrounded the First Tribe.

They couldn't see each other, but there seemed to be a special way of contact, and the five of them climbed up counterclockwise against the base of the wall at the same time, this time their movements seemed to be much bigger, the snow at the base of the wall was undulating greatly, and it seemed that they were all putting something on the base of the wall in the snow.

I guess they put the black spar they brought over at the base of the wall!?Chen Ling thought in his heart.

The five people climbed counterclockwise to the place where the previous person had started to climb, that is, one person climbed a fifth of a circle, and the five people together just surrounded the first tribe for a full circle.

If they were really placing the black hedron that I don't know what the hell it was, they should have used the black hedron to surround the entire First Tribe.

After completing the task, the five people gathered in the place where they had separated, and it seemed as if they had asked each other about the completion of the work, and after confirming that there were no problems, the five of them crawled back along the path they had come.

The way they came had formed a passage in the snow, and it was very easy to climb up, so they were much faster than when they came, and they had already returned to the edge of the snow forest at dawn, and without looking back, they had disappeared into the vast woods.

They never realized that all their movements were being watched from above.

......

After watching them leave in the air, Chen Ling flew under the wall, kicked the snow in the corner of the wall and saw the black hedron buried underneath.

He picked it up and pinched it in his hand and looked at it.

This black spar was not smooth, and the frosted surface looked a little rough, Chen Ling rubbed it with his hand. It was discovered that this thing had even shed a layer of black fine powder.

What's that?

Chen Ling continued to rub it. The black spar the size of a pigeon's egg was dropped with a layer of black powder, revealing a crystal clear transparent ore the size of a soybean kernel inside.

This small ore contained an aura that surprised Chen Ling. This aura is different from the stable aura contained in the Spirit Diamond, it is extremely active, as if it may burst out of this small transparent crystal at any time.

Chen Ling grabbed this small spar in his hand, walked forward for more than ten or twenty meters, and found another black spar, rubbing it, it also dropped a layer of black ash, and there was still a transparent spar the size of a soybean grain, and he walked forward for more than ten or twenty meters. A third black hedron was discovered.

Chen Ling didn't rub it away, took it in his hand and flew to the wall, and after saying hello to the guards on the wall, he flew straight to the door of Lan Chengying's house.

It's early in the morning, it's not dawning, most people are still asleep with the lights out, but the lights in Lan Chengying's room have been on, and Chen Ling saw a figure pacing back and forth in the hall from the window before it fell.

Chen Ling directly pushed the door and walked in.

Lan Chengying didn't feel the slightest surprise when he saw Chen Ling push the door in, but breathed a sigh of relief, and then pulled him to the chair, and he also pulled the chair and sat on the side with him.

"How are they?" asked Lan Chengying eagerly.

"Go back. ”

"Didn't they have a mission? Didn't they come in?"

Chen Ling did not answer his doubts. He scattered his contents on the table.

Lan Chengying was stunned for a moment when he looked at the things on the table, as if he didn't understand what Chen Ling meant by throwing this thing on the table. But after a closer look, his face changed greatly, Huo got up from the chair suddenly, his foot tripped on the foot of the chair and almost didn't fall back, as if he had seen a ghost.

"Know this thing?" Chen Ling asked.

"Where did you get this thing from?" Lan Chengying looked at Chen Ling with a little horror.

"The five of them stayed, and now I reckon there's a whole bunch of these things outside the wall. Chen Ling asked, "What is this? I see you're scared of this thing?"

Lan Chengying didn't feel embarrassed, nodded solemnly, he adjusted his mood, pulled up the chair and sat down again, he took three empty cups, carefully put two soybean-sized transparent crystals and a pigeon-egg-sized black crystal on the table into them, and covered them with lids.

When Chen Ling saw this scene, he felt that the thing in front of him was not simple, and looked at Lan Chengying waiting for his answer.

"It's something made by the natives, and in their words it's called Black Blaststone, and it's the product of a combination of two extremely active minerals. This small hedron that is transparent can produce a very large amount of explosive energy, and the black powder will dramatically enhance the aura effect after encountering the aura, and the two together can create a very violent explosion. Lan Chengying said tremblingly: "Fortunately, you didn't touch them with aura when you took them, otherwise the huge explosion power will instantly detonate other black blast stones, and the consequences will be unimaginable." ”

Chen Ling had never seen the power of the Black Explosion Stone, and he didn't understand Lan Chengying's trembling.

He said, "How powerful is this thing?"

"You can blow up a hill with just three or five pieces, and it is said that they use it to level the land. Lan Chengying explained.

This explanation gave Chen Ling a certain understanding of the power of this black blasting stone, and a look of surprise appeared on his face.

Three or five can blow up a hill, but he saw those five people put a whole circle around the wall outside the First Tribe, at least fourteen or five hundred, if they exploded together......

Not to mention razing the entire First Tribe, at least the impregnable wall outside the First Tribes must be blown up, right!?

They wouldn't have done nothing to destroy the First Tribe's defenses, and if they did, it would have meant attacking.

"Looks like the natives are planning an overwhelming war against your First Tribe. The corners of Chen Ling's mouth raised, and he said with a smile: "First remove your defenses, and then attack in a big way, with the strength of the natives, I think it should be a higher level than you, right? As long as their plan succeeds, the First Tribe will probably cease to exist in the near future." ”

Looking at the evil smile on Chen Ling's face, Lan Chengying seemed to see the evil smile of the indigenous leader after destroying the First Tribe, and a cold sweat couldn't help but fall on his forehead.

"Chen Ling, are you sure they have left?" Lan Chengying stood up.

"I watched them enter the snowy forest, and I don't know where to go this time. Chen Ling also stood up, and walked out of his room first as if he knew what he was going to do.

Lan Chengying didn't want to go out with him closely. (To be continued......)
