Not only that, but it will take time to release the water, if it is calculated like this, the injured clansmen will definitely not be able to hold out for long, what should I do?" Gu Chu's mood suddenly became heavy.

"Brother Gu Chu, the passage to the next floor has been dug!" the Black Rhino Patriarch walked over breathlessly, "What are you doing here?

Hearing the explanations of the other clansmen, the Black Rhino Patriarch's face changed.

Although the pool is not far from here, the distance between the underground lake and the pool is 100 meters higher, and the canal has to be very deep to draw water.

But then again, when the canal is built, will the injured people still be alive?

This question undoubtedly appears in everyone's mind.

After thinking about it, the Black Rhino Patriarch sighed bitterly, patted Gu Chu's shoulder, and comforted: "Brother Gu Chu, give up, we have done our best." ”

"These seven clansmen are all heroes of my greedy wolf alliance, and their names will be engraved here to show their bravery forever! I, as well as all the clansmen of the greedy wolf alliance, will not forget them!"

Obviously, the fact is that the underground lake is so large that it is impossible to dig a channel out of it in a short time, let alone fish from it, with just manpower.

"Alliance Leader, are you listening?"

Gu Chu didn't listen to the persuasion of the two, and he was constantly thinking about how to change the rescue plan in his mind at this time: "There is not enough time to dig the canal to the pool, if it is not enough, what if it is dug in another place? ”

"Your Excellency, you...."

"No, that would be too slow, time, tsk, it's still a matter of time!" Gu Chu frowned.

"Brother Gu Chu, are you still listening to us?"

"Digging channels doesn't work at all, so I can only find another way, but it's a pity that my soul refining secret method can't be lent to others because of the agreement, and in the state of the injured clansmen, even if I borrow them, I can't use it, it seems that I can only start from the environment..."

The black rhino patriarch and the hundred-legged patriarch called a few more times in the outside world, but Gu Chu turned a deaf ear, so that they could only look at each other, very confused.

"The abyss environment is special, there are underground lakes on the fifth floor, and it is normal to have several lakes on the ninth floor, and there are many areas for red stalactites, and there are many strange rocks and stones on the eighth and seventh floors. There are a lot of stones in this abyss..... Wait!"

Gu Chu's eyes suddenly flashed, and his face showed an expression of joy.

"I've figured out how to dig a canal!" Gu Chu was ecstatic, but he didn't say anything, but instead summoned a few members of his own family and let them go up to the sixth floor.

There, Gu Chu and others have found a lot of saltpeter with high purity.

"Hundred-legged Patriarch!" Gu Chu shouted.

"The old man is here, are you okay, Lord Alliance?" The hundred-legged patriarch was very strange, he was standing by Gu Chu's side, less than three meters away, why didn't he notice him at all.

"Oh, you're here, I'm sorry, I didn't notice you!" Gu Chu snorted, came to his side, and stretched out his hand, "Hundred-foot Patriarch, I've figured out a way to save my people, but you have to give me some of your powder to save people." ”

"Okay!" Without any hesitation, the hundred-legged patriarch immediately took out dozens of small bags under the animal skin coat, and placed them one by one in front of Gu Chu's body, allowing him to choose.

Looking at this amount, Gu Chu couldn't help but smile bitterly, "So many?"

The rescue method improved in ancient times is quite simple.

Since the stone ground here is so thick that it is difficult for ordinary people to mine, why not use more powerful explosives to blow up a channel?

For the homemade bombs in the previous life, the ancients had heard a lot of about it, and they also knew the content, and they only needed to try to combine them slightly to make unearthed explosives.

saltpeter, powder containing sulfuric acid, as well as charcoal blocks!

These things were readily available in ancient times.

In the middle of this abyss, there are a few areas that contain saltpeter, and they are so pure that they can be used once they are mined!

As for sulfuric acid powder, because it has many therapeutic effects, it has been used and purchased by the Baizu tribe for a long time, and there are many Baizu patriarchs at this time, plus among his tribe members, there are many people with sulfuric acid on their bodies, and after getting together, the amount of medicine is also considerable.

As for the charcoal, it is the best of the three materials.

Because after Gu Chu returned to the headquarters to replenish resources, he brought a lot of food and resources over, just in case, there were thousands of catties of charcoal, which was quite enough.

The three materials came together, and in ancient times, they were quickly made into quite earthy bombs.

Looking at the mudball-like bomb in his hand, Gu Chu sighed slightly, "It is more appropriate to say that it is an earthen bomb than a briquette." ”

Because the entire earthen bomb was covered in coal, and it was quite black, except for a lead made of animal hair left outside.

With the homemade bomb in hand, he went to a small canal dug by his people, and experimentally fixed the homemade bomb in it, and then lit the fuse.

".....

The beast hair lead burned violently, and Gu Chu made everyone who was already far away take dozens of steps back again.

"Boom!" After a few breaths, a loud bang hit the ground, and smoke and dust filled the sky.

Everyone in the greedy wolf alliance was stunned by this loud noise, even the clan elder, the black rhino, and the two patriarchs of the hundred-footed tribe were no exception.

"Brother Gu Chu, what the hell is this? It's so powerful!"

"It was like thunder in the sky, and the smoke and dust were gone.... Shh

Everyone saw that the small section of the canal had expanded hundreds of times, forming a pit-like shape, and when they looked closer, the depth of the canal had also been expanded several times, reaching a depth of more than ten meters.

"This, this, what method did you use, Lord Alliance, to make it so powerful!"

"It's terrible, just this time, it saves us a lot of effort!"

"And the means of the alliance leader, it is enough to deal with the situation..."

Gu Chu saw the scene under the canal, and he was also quite surprised, "When did the power of the homemade bomb become so great?"

But soon, he understood why.

The purity of saltpeter in the abyssal space is quite high, reaching the point where it can be used as soon as it is mined, and the same is true for sulfuric acid powder, the carbon is even better, and the purity of various materials is high, so that this homemade bomb can have such an effect.

"Hahaha, my people, don't panic, this is one of the means that I was given by Lord Greedy Wolf when I was blessed by Lord Greedy Wolf himself!" Gu Chu said blindly, he raised his hands and shouted, "Thank you, Lord Greedy Wolf!"

When the greedy wolf clansmen heard this, they immediately felt a sense of pride in their hearts, and they raised their arms one after another, and said in a loud voice like the ancient beginning:

"Thank you, Lord Greedy Wolf!"

"Thank you, Lord Greedy Wolf!"

"Thank you, Lord Greedy Wolf!"

At this point, Gu Chu hurriedly stopped them, "At this time, the main purpose is still to open channels, and with the means of Lord Greedy Wolf, we will definitely be able to save the clansmen!"
