At the same time, at the mouth of the valley.

"It's been a long time since the last thunder sounded, right?"

The Terran chief turned his head and asked Chief Peng, who was not far away.

"Hmm. ”

Chief Peng nodded, and said with a happy face: "They definitely don't have thunder weapons anymore, let's continue to attack!"

"Good. ”

Hearing this, the Terran chief nodded.

At this time, the fighters were accustomed to the sound of explosions from time to time, and they were no longer as afraid as before.

However, while the Terran chief nodded, he couldn't help frowning, feeling that something was wrong.

"Kill!"

At this moment, Chief Peng's shouting of killing had already sounded.

The Terran chief didn't think much about it, and also led the warriors behind him to kill in the direction of the cave again.

......

"Smack!"

At the cave, looking at the crowd that rushed to kill again, Lin Luo casually threw away the clay pot in his hand.

At this time, there was a long, yellowish lead in front of him.

It was the one he had just sprinkled with sulfur powder, and the lead extended to the ten bronze thunder fires stacked together at the entrance of the cave.

That's right!

Lin Luo's purpose in leaving those ten bronze thunder fires was to blow up the hole before leaving.

In this way, if the enemy wants to enter the cave, he will have to spend a lot of effort to clear the collapsed rocks.

"Phew!"

Soon, after discarding the clay pot containing the sulfur, Lin Luo used a burning torch to directly ignite the sulfur lead.

Among the sulfur, Lin Luo added the only remaining nitrate of the tribal alliance and a small amount of charcoal powder, so it was easy to ignite it.

After seeing the fuse ignited, Lin Luo rushed towards the depths of the cave without looking back.

"Boom!" "Boom!"......

Soon, about a dozen seconds later, a dense explosion sounded.

Previously, Lin Luo had asked Yong to dig the rock at the mouth of the cave, destroying the originally stable structure.

At this moment, under the simultaneous explosion of ten bronze thunder fires, a large piece of cracked rock collapsed, directly blocking the entrance of the cave.

"This ......"

In the valley of the alliance, the enemies who had already rushed to the mouth of the cave immediately were all stunned after seeing this sudden explosion.

Originally, they were all ready to start a fierce battle with the tribal alliance.

Unexpectedly, instead of responding to the battle, the tribal alliance directly blew up the entrance of the cave.

"Are they trying to kill themselves?"

One of the chiefs asked, staring at him with a look of astonishment.

"No way. ”

Hearing this, Chief Peng immediately shook his head and denied this possibility.

Even small tribes will resist desperately in the face of a strong enemy, and it is absolutely impossible to commit suicide.

Not to mention a powerful tribe like the Tribal Alliance.

"The interior of this cave is so large that it is absolutely impossible for it to collapse completely. ”

At this time, he looked at the entrance of the cave that was sealed by rocks, and said loudly, "Now, all the people of the tribal alliance and a large amount of food must be stored in the cave.

They want to fend off our attack by sealing the hole. ”

Ao had come to the Valley of the Alliance, and he knew more about the Tribal Alliance than anyone else.

"No wonder I was in the valley before, and none of the tribesmen of the tribal alliance saw it, and I couldn't find any food, so they were all hidden in the cave!"

Hearing this, the chief immediately said, "Let's dig up these stones now and see where they can hide." ”

"Dig me the hole!"

Chief Peng didn't say much nonsense and gave the order directly.

"Chief Peng, let your tribe's Peng Bird scout around the valley. ”

At this moment, the Terran Chief frowned slightly and said to Chief Peng.

"Scouting?"

Hearing this, Chief Peng couldn't help but be stunned.

But soon, his face changed slightly, and he asked, "Do you suspect that there is another exit from this cave?"

Many tribes, when choosing a place to live, usually leave a hidden retreat to evacuate in case the tribe is in danger.

So, at this moment, when I heard the Terran chieftain ask Peng Bird to reconnoiter the neighborhood.

Chief Peng quickly thought that there was probably another exit to the cave in front of him.

"That's right. ”

The Terran chief nodded directly and said, "Since we entered the residence of the Tribal Alliance, we have not seen any people from the Tribal Alliance.

Moreover, the thunder weapon they used before would not cause us any harm at all.

But it's still used every once in a while, and it looks more like a deterrent to keep us from approaching the cave. ”

Before, the Terran chief had already noticed something, and felt that something was wrong.

At this moment, after seeing Lin Luo directly blow up the entrance of the cave, this feeling became even stronger.

And Chief Peng's face suddenly became ugly after listening to the analysis of the Terran chief.

Immediately turned his head to Ao and shouted, "Ao, you immediately take two warriors to reconnoiter around the valley to see if there is any trace of the tribal alliance fleeing." ”

"Yes. ”

Hearing this, Ao nodded in response.

Immediately, with two warriors, each riding a Peng bird war pet, he quickly flew towards the sky.

However, the excavation of the cave mouth has not stopped.

Although it is very likely that the Tribal Alliance has fled, it is only speculation after all, and the hole must be dug up to confirm it.

......

"Whoa!"

Outside the valley, at the entrance of a hidden cave.

With the sound of rushing water, Lin Luo walked out of the cave.

The exit of this cave leading to the outside of the valley is located just below a small waterfall, and it can be said that it is very secret.

"Lin Luo!"

Seeing Lin Luo's figure appear at the entrance of the cave, the people who left first immediately shouted at him.

"Let's go, get out of here at once. ”

Lin Luo ignored the animal skin clothes that were splashed by the water, and said directly to everyone.

"Yes. ”

Hearing this, everyone immediately nodded in response.

Following behind Lin Luo, he quickly left here.

"Wow!"

In the process of running, a sharp roar sounded.

Hearing this roar, Lin Luo turned his head to look back, and then looked at the sky that had already darkened.

I secretly thought in my heart: I should be able to survive this night!

At this time, the sky had already darkened, and although Peng Bird's eyes were sharp, he did not have the ability to see at night.

It's not so easy to find this hidden exit.

Therefore, Lin Luo quickly retracted his gaze and concentrated on rushing away.

Now their most important task is to catch up with the migratory team as quickly as possible.

......

"Boom!"

Pushing away the last few stones blocking the road, the hole that had been sealed by the rocks reappeared in front of everyone.

"Let's go, beware of enemy attacks!"

Seeing that the entrance to the cave had finally been opened, the Terran chief waved his hand at everyone.
