The core area of the Guardian was surrounded by biological tissues, and the biological tissues were destroyed by the poison of the zombie snake, and the two of them turned around for a long time, but they did not find a passage to enter the core area.

What can I do? The two of them suddenly went numb, and they came together and meditated on their brows.

"Or ...... Let's go back the same way, contact the leader first, and listen to everyone's ideas? "I really can't think of a way, Fenghua reluctantly built yì road.

"That's the only way to do it." The black bear sighed.

He couldn't remember how long it had been since he had been on a mission on the ground, and if he had been on a mission, he would definitely not have forgotten to bring enough communication repeaters, but now, he didn't even remember it.

Through the guò escape route, it is possible to leave the Guardian very easily, but in that case, it will be troublesome to enter the Guardian again, so returning the same way is the only feasible solution.

It took more than ten minutes for the two to fly back to the breach when they entered, until they returned to the breach and found that the zombie snake had returned, a zombie snake was eating near the breach, the mouthparts as thick as a tunnel stabbed into the biological tissue, and a large amount of flesh and blood were sucked away by the mouthparts, but in a few breaths, the mountain-like biological tissue was sucked up by the zombie snake.

As for the lifeboat stuck in the breach, it has long been unknown where it flew.

The black bear was startled, and ran back with Fenghua.

Just kidding, this thing doesn't feel big from a distance, but it's a giant up close, and it's not enough for the two of them to stuff the zombie snake between their teeth, it can be said that they will die if they are scraped, and if they don't hurry up, they will make do with it. What is that not looking for death?

After flying through several passages in a row, hundreds of meters deep into the battleship, they could still feel the vibration caused by the zombie snake eating, and the two of them couldn't help but look at each other on the ground, and couldn't help but laugh at it.

"There aren't many opportunities to get up close and personal with cosmic creatures." The black bear made a bad joke.

Fenghua fought back without showing weakness: "There are not many opportunities to wander around in the belly of cosmic creatures, why don't you go in and have a look?" ”

The black bear laughed: "It's not that I haven't been in, rare!" ”

After chatting and waiting, after about an hour and a half, the vibration gradually subsided, and the two men slowed down and cautiously approached the breach. It was only discovered when it was near the breach. The breach that was originally covered by biological tissue has been completely empty, and has become a huge hole with a diameter of hundreds of meters, and no biological tissue can be found as far as the eye can see. I was actually sucked clean by the zombie snake.

The black bear grinned unconsciously. But I don't know what to say.

Fenghua shook his head in embarrassment. Poked the black bear with a finger: "What are you waiting for?" Get in touch with the ground! ”

"Oh, okay." The black bear agreed, but asked again. "You say, will the zombie snake swallow all the biological tissue?"

"I guess what?" Fenghua asked strangely.

"Core area, of course!" The black bear's eyes lit up, "They've eaten up the biological tissue, so won't there be anything to stop us from entering the core area?" ”

Fenghua was stunned: "That's right! Let's go, let's go! ”

"Come back!" The black bear grabbed Fenghua, "Silly girl, how slow it is to go inside, let's fly directly from the outside!" ”

"Will it work?" Fenghua hesitated a little, "If the zombie snake comes back......"

"No, it won't." The black bear said confidently, "They come here to eat, the biological tissues have been eaten, and the zombie snake does not gnaw steel, it is like eating up the meat and only the bones are left, even the dogs eat the bones are made up, they will not come back to lick the bones, right?" ”

Fenghua was amused by him and laughed: "You have a lot of reason, let's go quickly." ”

The black bear laughed and grabbed Fenghua's hand, and his tall stature made him drag Fenghua out of the Guardian like a father holding a child, and flew along the bare edge of the Guardian in the direction of the core area.

However, the two of them were completely dumbfounded when they flew to the location of the core area, only to see that there was only a large pit with a diameter of nearly a thousand meters left in the place where it should be the core area.

"Nuclear, what about the core area? Where did it go? "The black bear can't say anything.

The core area is so big and a ton of metal, how can it be said that it is gone? It's not a biological tissue, and it's impossible for a zombie snake to eat the core area.

Fenghua keenly noticed the torn metal structure under the location of the core area, and couldn't help but guess: "Is it that the zombie snake wants to eat the biological tissue under the core area, so it demolished the core area?" ”

The black bear smiled bitterly: "I'm afraid there is no other explanation." ”

"What now?" Fenghua asked.

"What else can I do, contact the boss and see what he means." The black bear immediately called, "Chief, can you hear me?" Hear it, please answer! ”

Ye Feikong, who was welding the steel plate, aimed the beam at the weld steadily: "Hear, how is the situation?" ”

"The situation is very bad, much stricter than expected!" After that, Black Bear gave a brief introduction to the situation of the Guardian, focusing on the loss of the core area of the Guardian.

Ye Fei's hand shook, and he almost didn't weld himself to the bulkhead: "The core area is gone?" ”

"It's gone." The black bear affirmed.

"Fuck, fuck!" Ye Fei scolded angrily, "Damn zombie snake." ”

"Chief, what now?" Black Bear asked, "The Defender has no core area, but the rest of the mechanical parts are intact, and the reactor is still working. ”

Reactor?

A flash of inspiration flashed in Ye Fei's mind: "Old Xiong, you really reminded me that there is a task that must be handed over to you!" ”

"What task?" Black Bear asked.

"We're running out of fuel, you have to find a way to get some fusion fuel back from the Guardian's fuel depot!" Ye Fei said.

"How's this going? If it was small, I could still stuff it into a lifeboat and take it down, but I can't help it if it weighs a few tons. The black bear immediately refused, this is a task, this is fatal!

"I didn't let you take the whole tank down!" Ye Fei raised his voice, "Just bring some back, can't you do anything about ten catties and eight catties?" ”

"Well, that's fine." The black bear began to figure out what liquid hydrogen to use to bring this thing to the surface.

It's easy to bring liquid hydrogen, but after sending it down, how to store it is a big problem.

Gas liquefaction requires both pressure and a sufficiently low temperature, and if it is not kept cold enough, the liquid gas expands, exerting tremendous force on the container.

The temperature in the universe is extremely low, and the hydrogen tank will not have the problem of heating up, but the ecological environment of the third planet here shows that the average temperature will never fall below zero!

Zero is cold for humans, but it's too hot for liquid gases, so hot that they have to lose their temper. (To be continued......)
