There is nothing visible in the depth of more than 200 meters in the underground sea, a huge submarine crater billows black smoke in the seawater, black metal cooler gushes up to a height of sixty or seventy meters in the water, and within two kilometers of the crater, the high temperature and high pressure generated by the boiling of the groundwater make the waters appear turbid.

The sea urchin base stopped its forward momentum two kilometers away, and if it got closer, the internal mechanism of the base might be destroyed by the heat of the active volcano and the corrosive nature of the surrounding currents, and Liu Yu did not think that anyone could survive in that area.

The shell of the sea urchin base slowly opened, and a transparent pipe more than two meters thick extended from the sea urchin base to the direction of the crater, and the transparent pipe was not affected by the temperature and corrosive liquid around the volcano and easily penetrated into the crater emitting black smoke. Then I saw a crimson light emerge from the crater, and the red streamer rushed along the transparent pipe to the sea urchin base.

The red streamer is not the magma on the bottom of the sea, but the energy directly absorbed and transformed through the transparent pipe, with the flexibility and transformation ability of the sea urchin base, most of the energy absorbed from the volcano will be used for the weapon system of the sea urchin base.

The Sea Urchin Base happily steals the energy of the submarine volcano in the underground sea, and no team comes to interfere or sneak attack, and most of the teams are still directly using ionization to obtain energy from the water. As for the energy or other energy materials on the seabed, other teams have no plans to come over to mine for the time being, which is actually a huge advantage that Liu Yu gained by building the base in advance, and the right decision can lead the team to win the bargaining chips.

From the beginning of collecting energy to the storage of spare energy blocks, Liu Yu spent a total of about ten minutes. By this time, the entire game had been played for an hour and twenty minutes.

Liu Yu did not stay near the volcano for a long time, because at this time, the various bases also began to explore deeper into the underground sea, and the sea urchin base was not exposed to everyone's field of vision, she wanted to maintain the mystery of the sea urchin base and solve a lone group in the shortest possible time.

The sea urchin base has enough energy to unscrupulously turn on the stealth system and float upward, Liu Yu has already arranged the jammer in the passage down when she came down, so as to prevent the enemy from discovering the passage directly to the defense base above, and now she started from the vicinity of the jammer and touched the direction of the enemy's traces along the rock wall above the underground sea.

Liu Yu always thought that she was doing all this covertly and carefully, but she didn't know that everything she did was now clearly displayed in the eyes of her good sister Alyssa.

Under the thick smoke of the crater, which Liu Yu thought would definitely not be human, a spiderweb-like structure stood more than ten meters above the crater. The black smoke from the volcano completely conceals the web-like structure, which floats up and down like a spider's web in the wind and rain, but due to the heat flow of the crater below, the web-like structure is mainly stirred up by the heat flow.

The network structure adsorbs the metal materials that erupt from the volcano on it, most of the useful metal materials are all left by the network structure, and the useless materials are all filtered by it and let them surge near the crater as a shield.

This reticulated structure is the work of Li Chen's Sixth Team, but it is not the main body of the Sixth Team's base structure that can absorb metallic materials and energy above the crater.

The real Sixth Group Base has opened a ring structure with an inner diameter of more than 10 meters and an outer diameter of more than 600 meters around the crater, and this ring structure is enclosing the crater in the center, and the main axis of the network mechanism above the crater that collects various materials and energy is all rooted in the center of this ring mechanism.

If anyone could see the profile of the entire volcano, it was now as if it had been capped by the sixth group, and this cap was like a parasite greedily absorbing the energy of the entire volcano.

"You just let Xiao Yu go?" Alyssa watched Liu Yu's sea urchin base gradually disappear into the visual range of the base, and asked Li Chen curiously.

"I'm a peace-loving person!" As he spoke, Li Chen gave an order to Lin Zhi and Alyssa, "Develop metal corrosive bacteria as soon as possible, and next time anyone dares to steal our volcanic energy, they will be given a big gift!" ”

Li Chen is naturally not the kind of benevolent person, but now the crater base does not have a decent means of attack, and the sea urchin base is developed by himself, he naturally knows the survivability and attack ability of the sea urchin base, and at this stage, if he wants to leave the sea urchin base, it will be a defeat at most, so when Liu Yu used the energy collector to collect volcanic energy, he decisively let go of the energy collection network of the crater.

The sixth team found three volcanoes on the bottom of the underground sea, and the one they now occupy is actually the smallest one, with a crater diameter of only about 500 meters, and a large number of microorganisms have been found near all three craters.

Seeing those microorganisms, Li Chen and Alyssa made a decision to abandon the larger volcano together. Because there are no creatures in the general game map, and even organic matter will not exist, but microorganisms appear here, which proves that the volcano is actually an important location for the game to change, and it is too risky to build a base in a crater that is too large, and even this 500-meter crater Li Chen actually has a great negative attitude.

If there is any construction that the players of the medical device simulation want to do in this game, it is probably on these microorganisms in the crater.

"Skinny monkey, fat man, how is the construction of the earth's environmental mimicry area?" Establishing a base near the crater, Li Chen now does not have to worry about being attacked by other groups for the time being, he has already sprinkled a new type of reconnaissance robot dozens of kilometers near the volcano, as long as someone approaches, he has plenty of time to hide or build fortifications.

"It's ready, now it's ready to build a volcanic energy conversion system." The skinny monkey replied.

The volcanic energy conversion system is not a material structure of the transparent pipe that Liu Yu just stretched out from the sea urchin base, it is just an energy harvesting system, which can only convert the heat energy of the magma in the crater.

The volcanic energy conversion system directly uses the entire volcano as the energy block of the base, which can directly integrate the energy of the volcano into the various functional structures of the base, and the network structure above the crater will be transformed from an energy harvester into an energy release element after the energy conversion system is completed, that is, the attack weapon of the crater base.

The volcanic energy conversion system needs to be operated by Li Chen, Thin Monkey and Fat Man at the same time, and on the inside of the newly built ring base, eight circular pipes stretch at a 45-degree angle to the magma layer below the crater at the same time. I don't know what kind of material the annular pipe is, but it is not affected at all in this high temperature environment and goes straight into the magma. As the pipeline entered, eight transformers made by Skinny Monkey and Fat Man also immersed themselves in the magma along the pipe, and the orange energy bar suddenly exploded after the transformer sank into the magma, and the suspended working systems in the crater base also started to operate automatically.
