Douluo Continent: The Book of Witness and Peerless Tang Sect

After throwing the mini-tank into the lava, Longyou activated the mini-tank's built-in drive and sonar detector through Byrne.

The small tank's internal space was already limited, and the operating space for Longyou was also small, so the tank's functions were relatively rudimentary. Its detection methods were limited, and its continuous operating time was also very limited.

Fortunately, there was nothing in the lava lake that could block the transmission of sound waves, and the small tank sent back a complete sound wave detection map not far from the crater cliff.

The crater is not small, so the lava lake is naturally not small either. However, this lava lake is only open up to a height of two or three meters on the surface. Further in, the lava flow narrows rapidly, and the rock walls of the mountain begin to thicken.

What lies deep within the magma lake, within the magma that connects to the earth's veins through the mountains, is something that a level-four sonar soul-guided device cannot clearly detect.

However, none of that matters. All Long You needs to know is that there are indeed Boiling Fish Soul Beasts in the surface lava lake, and that among these Boiling Fish Soul Beasts living in the surface lava lake, there are those whose age meets He Caitou's requirements.

Seeing that the sound waves had not disturbed the boiling fish living in the lava lake, Long You immediately controlled the small tank to return along the same route.

The small tank wasn't very fast, so while it was returning, Longyou began to make some preparations.

First, get Beibei and Tang Ya off the mountain. These two aren't high-level Soul Masters, and they're only equipped with powered exoskeletons, which aren't fully encased and allow for free temperature control. They're already somewhat dehydrated from the high temperature of the volcano, so there's really no need for them to stay here any longer.

Then, Long You sent a private message to He Caitou on the internal communication system: "Senior Brother He, do you know what I want to do?"

"I don't know. The temperature of this lava lake is too terrifying. Even if we can use a remote soul tool to launch an attack, if the Boiling Fish doesn't show itself on the surface of the lake, we can't lock onto it, and our attacks can't actually penetrate the scorching lava lake."

"Hehe, of course I know. But, senior brother, did you know that magma can conduct electricity like water?"

"Conductivity? I actually... wait, you're going to electrofish?"

"Hehe, hehe, that's right. I remember you should have a set of electric wall generating soul tools to surround this volcano."

"If we throw plasma bombs into the lake later, these Boiling Fish might leap over the Dragon Gate like carp. If they jump out of the lava lake, we might be in trouble. It's best to keep them all in the lava lake until they're all belly up, then we can pick out the good ones."

"Hey Xiao You, is there some big stuff in this lava lake? If we discharge electricity, will it scare out those guys we don't want to mess with?"

"Of course there are. The magma temperature inside this crater is so high that it's perfect for the Boiling Fish to live in. How could there not be? However, there are no surface magma lakes."

I just looked at it, and judging from its size, the largest of the Boiling Fish living on the surface of the lava lake is only about eight thousand years old.

Considering the power of the plasma bombs we made, it's good enough if they can stun these Boiling Fish; they won't affect the deeper layers and won't produce any big catches.

"Okay, I'll go install the electric wall."

He Caitou's soul-guided power armor left silently, and Long You opened a private communication channel with Zhang Lexuan.

"Senior Zhang..."

"Just call me Senior Sister. Now that you know, there's no need to hide it when we're alone. What? Need my help?"

"Hehe, Senior Sister is brilliant. We'll use some methods to stun the boiling fish in this surface lava lake with electricity. Then, we'll have to trouble Senior Sister to help bring up those little fish that couldn't withstand the voltage and died, as well as that boiling fish that's about 6,600 years old."

"Six thousand six hundred years? For He Caitou? What about yours?"

"Well, there aren't any suitable ones. The remaining Boiling Fish is over eight thousand years old; it can't withstand the strain."

"Alright, boiled fish soup is delicious, I'm looking forward to having it tonight."

"What's the point of just drinking fish soup? Won't you try the grilled boiled fish, Senior Sister? Won't you try the boiled fish fillets, Senior Sister?"

"You're back. Get to work. I'll be waiting tonight."

There's not much to say. A whole fish feast was enough to defeat a Soul Saint who could fight a Soul Douluo. If Long You and He Caitou still had problems, it would be unbearable to watch.

An electric wall was erected, over three meters high, with an additional two-meter-long electric grid extending upwards. Plasma bombs were dropped in, and visible incandescent electric currents surged wildly through the lava lake.

After about two breaths, some of the boiling fish began to turn belly up, while others leaped out of the water to attack Long You and He Caitou.

However, the electric wall was not just for show. Most of the attacks launched by the Boiling Fish were deflected back with terrifying electric current. The remaining attacks, although they failed to deflect back, did not break through the electric wall's defense.

The terrifying electric current raged in the lava lake for ten seconds, and the entire lava lake went from boiling to calm. After another ten seconds, Long You saw that the boiling fish he had detected had indeed all floated to the surface. Only then did he notify He Caitou that they could prepare to open an opening in the electric wall.

"Be careful with your senior brother. Prepare several layers of soul-guided defensive shields. I'm afraid there might be someone faking unconsciousness inside."

"Don't worry, Xiao You. As long as they show themselves, I'll make their fainting act real."

As soon as He Caitou finished speaking, it was unclear what switch he pressed, but suddenly a row of gun muzzles appeared on the pillars that generated electric walls. Then, the muzzles flashed with electricity, and beams of lightning accurately struck the boiling fish floating on the lava lake.

"Wow, Senior Brother, you've given me a really big surprise!"

"This concept is still yours: the best way to encircle the enemy is to completely incapacitate them. I'm thinking, since plasma paralysis rays and electric walls are both electric, why not combine them?"

Senior Zhang, I need to ask you for help to open a channel on my end.

Zhang Lexuan moved quickly; in the blink of an eye, she tossed a large, nearly 1.7-meter-long boiled fish into He Caitou's hand and a storage bracelet that didn't look very valuable into Long You's hand.

He Caitou paused for a moment, then hurriedly put a soul-binding device on the large fish in his arms. With Long You's help, he quickly dismantled the electric wall and activated the soul-guiding device.

They returned to camp safely. He Caitou began preparing for the soul ring absorption, while Long You started dealing with the boiling fish that Zhang Lexuan had caught.

There were more than twenty of them, the vast majority of which were at the ten-year level or less than five hundred years old. These boiling fish all had soul rings floating on their bodies, clearly indicating that they had not been able to withstand the electric shock.

However, there was another giant Boiling Fish that had reached a meter in length. This one didn't have any spirit rings, so it was obviously just unconscious. The reason it was here was probably because it was too delicious.
