As time passed, a sense of crisis gradually enveloped An Ruoxuan's heart. Pen, fun, pavilion www. biquge。 info It was an inexplicable sense of crisis, coming from the soul, urging An Ruoxuan to leave here. As the sense of crisis intensified, An Ruoxuan gradually couldn't sit still, and there were some things they had to do.

An Ruoxuan jumped out of her light mecha, and a milky white nano weapon gradually appeared on the surface of her body, and she decided to personally release the liquid nitrogen in the -20 layer cooling tower. "You guys continue to guard here, and I'll go to the -20th floor alone to have a look."

"Okay, you stay safe." There is no retention as everyone imagined, and there is no need to go together as everyone imagined. For members of the Zodiac Clan, there are two things that are most important: recognize yourself and believe in your partner. Among the more than 100 people present, only An Ruoxuan had the ability to secretly shuttle among the star insects, and it was a burden for the others to go.

An Ruoxuan quickly came to a hole that was broken by a sword mantis beast, jumped forward, and jumped directly from the hole. When she was still in mid-air, An Ruoxuan quickly switched to a stealth state. After a slight relay turn in the air, An Ruoxuan flew directly towards the wall on one side.

An Ruoxuan directly and silently clinged to the wall like a gecko, the knife mantis beast relied on piercing its claws into the wall, and An Ruoxuan relied on the microscopic mutual attraction between the nanometal particles and the wall, which is the same principle as glue and tape.

At the moment when An Ruoxuan was transformed in the air just now, the star insect had already discovered An Ruoxuan. After An Ruoxuan entered a high degree of invisibility, although the star insects lost An Ruoxuan's specific coordinates, they could definitely have a human mixed in, and all the star insects entered a slight state of riot.

After An Ruoxuan's nano armament entered the stealth state, it was able to isolate 99.9% of the information emitted by An Ruoxuan herself. Whether it is sound, light, heat, electromagnetic disturbance or other physical and chemical information, nano armament can perfectly intercept it and convert it into the energy it needs.

As for the remaining 0.1 percent, half of it is disturbed by the fact that An Ruoxuan does exist to the surrounding environment, after all, An Ruoxuan is still an entity; The remaining half is the eyes, the eyes are the windows of the soul, even if An Ruoxuan enters the state of invisibility, if she always stares at people of the level of the captain of the Zodiac team, she will still be sensed by the other party.

Even sometimes, if An Ruoxuan has killing intent towards the target in a stealth state, including some ordinary wild animals that are the targets of the experiment, they will feel uneasy and panic. As for the exact scientific principle, it has not been explained clearly, and there is no shielding.

However, since An Ruoxuan learned to restrain her killing intent and emotions, it has been difficult for anyone to find An Ruoxuan's traces anymore. Not even the other people who are also the captains of the Zodiac team, not even the alert wild animals. But in the last fight with the Blade Warrior, An Ruoxuan clearly sensed that the Blade Warrior should be able to sense her presence slightly.

The cooling tower on the 20th floor is not in the Tower of Babel, but in a separate building in the northeast corner of the 20th floor, which also saves An Ruoxuan a lot of trouble. What's even better is that the cooling tower can now be said to be not far from An Ruoxuan, and the hole where An Ruoxuan came down was also specially selected for this reason.

In the middle of that cooling tower was a huge metal tank containing more than two hundred tons of liquid nitrogen. What An Ruoxuan needs is to completely release the liquid nitrogen in that storage tank, and let the liquid nitrogen flow and vaporize arbitrarily throughout the -20 layer. Two hundred tons of liquid nitrogen can at least bring the temperature of the -20th floor to below minus fifty degrees, which is absolutely unfriendly for star insects.

But now the question is how to sneak into the cooling tower without being noticed by the star bugs. In order to prevent liquid nitrogen leakage, the access control of the cooling tower, as well as the storage tank itself, is tightly protected from leaks. After the underground base was disabled, the entire cooling tower was mechanically locked. If you want to open it, you either need to recharge it or brute force it.

Now the possibility of recharging under the shroud of the Stargate Barrier is almost zero, and the only way left is to brute force. An Ruoxuan adjusted the angle of her body and slowly moved upward. The cooling tower is almost the same height as -20 floors, and climbing to the top of the cooling tower is the only feasible solution for An Ruoxuan at present.

An Ruoxuan is currently more than 100 meters away from the top of the cooling tower, and it took An Ruoxuan half an hour to move this 100 meters. After climbing to the top of the cooling tower, An Ruoxuan temporarily relaxed. This is the blind spot of the star insects, and some subtle movements are not visible to the star insects.

It was much easier to do next, and a short sword gradually appeared in An Ruoxuan's hand. The short sword made of nano-metal sharpened like clay, easily opening a small opening at the top of the cooling tower that was just right for one person to enter and exit. An Ruoxuan then carefully climbed in, and a huge metal can appeared in front of her eyes.

The metal tank where the liquid nitrogen is stored is structurally strong and has several layers. Of course, this still can't stop An Ruoxuan's nanoknife. An Ruoxuan used the nanometal knife in her hand to cut off many parts of the tank layer after layer, but she did not completely puncture it.

Subsequently, An Ruoxuan manually activated the emergency mechanical pressurization device of the cooling tower. The metal-fueled engine then starts directly, driving the complex pressurized parts to continuously increase the pressure in the metal tank. After smashing the safety valve, An Ruoxuan climbed out along the small opening again, and quickly crawled towards the hole not far away.

Although An Ruoxuan is gone, the emergency mechanical pressurization device of the cooling tower is still in operation. The overall structural strength of the metal tank has been damaged, and the parts cut by An Ruoxuan have undergone obvious deformation. The current pressure is still within the design allowable range, but the tank is no longer able to withstand such pressure.

"Bang......" Before An Ruoxuan returned to the -19th floor, a violent explosion accompanied by strong cold air came from the cooling tower. The main material of the cooling tower is only a relatively ordinary special metal, under the low temperature and the huge explosion force, the whole was blown up with holes, and the liquid nitrogen in the original metal tank began to spread wildly.

Starworms, like the original insects on Earth, are not very tolerant of cold. Larger star insects such as tank beetles and wyvern beasts can still move normally, but small star insects like the ordinary green-striped sword mantismon, especially poisonous explosion insects, instantly lose most of their vitality, and they almost lose their mobility.

"Successful", although An Ruoxuan is relatively close to the cooling tower, the good defense ability of the nano armament perfectly shields the impact of the explosion and low temperature, and An Ruoxuan does not feel uncomfortable. Just when An Ruoxuan was excited, the star gate in the distance suddenly bloomed with a violent light, making An Ruoxuan's heart as cold as the outside world.

"Are you still coming?"
