Returning to the end of the world before the natural disaster, I emptied the world of supplies

"Yes. This is one of the only three wild biological germplasm resource banks in the country. It is very important and special, so the level of protection is much higher." Song Haitao walked forward and looked at the severely damaged steel door. He frowned:
"This is a high-level security door used in the bank's underground vault. It usually requires triple verification of fingerprint recognition, retinal scanning and password by an authorized person to open it. Now it's all destroyed. How to open it is a problem."

Sun Jingtao suddenly had an idea, "Why not let Jiang Ye give it a try. Isn't he the best hacker?"

Song Haitao shook his head. "Even if he comes, he can only crack the password at most. There is no way to solve the fingerprint and retina problem."

Jiang Yan said nothing and secretly let Hua Bao out.

As usual, Huabao turned into cardboard and crawled into the crack of the door, but soon it found that these two ordinary steel doors had no gaps at all.

Frustrated for the first time, Hua Bao pouted and said, "Mom, this is closed, I can't get in."

Jiang Yan was startled. "Doctor, is there no gap in this door?"

Song Haitao didn't understand why she asked this, and subconsciously said:

"No. The vault's protective door has a sealing strip on the door body. Once closed, the sealing strip can form a tightly sealed environment with the door frame. This is also to prevent the invasion of natural disasters such as water and fire."

After he finished speaking, he took the emergency light from Jiang Yan and checked the wall bit by bit.

Jiang Yan took out a flashlight from her bag and said, "Doctor, won't all the places we're going to in the future be like this?"

"Those are all kept and stored by the authorities. I have authorization for most of the access controls. However, there are also some special situations, similar to -" Song Haitao paused, turned his head and looked around habitually, then continued:
"After the extreme cold weather, we will face global oceanization. Except for a small amount of materials stored in the mountains, most of the materials will be left in some underground warehouses because there was no time to transfer them."

Sun Jingtao reacted quickly and asked, "Does that mean we are going to the bottom of the sea?"

Song Haitao nodded: "You can understand it that way. It's even more difficult than going to the bottom of the sea. After all, the general seabed environment is not as complicated as an underwater city. That's why many engineers and professionals are arranged in the accompanying team."

Jiang Yan: "."

It seems that this national-level zero-yuan purchase is not as easy as imagined.

"Why do I feel like I'm joining a tomb-robbing team?" Sun Jingtao was not frightened by the difficulties. Instead, there was a hint of excitement and anticipation on his face.

Song Haitao's face turned serious. "Xiao Sun, although your analogy is a bit inappropriate, the treasures obtained from tomb robbing are nothing compared to the country's most important treasures."

"Doctor, how about we go upstairs and check from the roof to see if we can find a gap or something?" Sun Jingtao tried to pry the wall next to the steel door with a dagger in his hand. After prying for a long time, he only pried off a small amount of dust.

Song Haitao frowned, "There are also steel plates inside the walls here. These steel plates are not as resistant to low temperatures as the metals in the Yao Ben base, but their toughness is better than that of ordinary steel. In addition, the temperature here is higher than outside, so it may be difficult to damage them."

"No wonder those people struggled at the door for so long but still got nothing. However, the main reason is that they lack powerful weapons." Sun Jingtao said, and looked at Jiang Yan, "Jiang Yan, how about trying the heavy machine gun?"

If he remembered correctly, there was an M2HB heavy machine gun in the AS area ammunition depot before, and the pointed boat tail armor-piercing bullets on it could penetrate 20mm thick steel plates. The steel plates here were very thick, and after shooting a few more times and penetrating the steel door or wall, he could find other ways to widen the entrance.

After he finished speaking, he slapped his head and said, "If the plasma cutting gun hadn't run out of power, it should be easy to use that.

After all, the thickness of the metal here is very thick, but its strength and toughness are obviously not as good as those special metals."

Jiang Yan smiled, "If you hadn't told me, I would have forgotten it."

She took off her backpack and pulled out the plasma cutter.

Soon, the large generator and engine were also taken out.

"Doc, Brother Tao, put these on." Jiang Yan handed two pairs of noise-isolating headphones to the two of them and put on one herself.

There was a flash of shock in Song Haitao's eyes, "Jiang Yan, you must take good care of your backpack." "Yes, Doctor, I will." Jiang Yan said, put on a pair of protective sunglasses, and walked towards the steel door with the cutting gun.

"There's still electricity?" Sun Jingtao was also shocked.

Jiang Yan nodded, "Yes."

There are too many things in her space, but sometimes, she really can't remember them.

Especially today, after traveling for half a day in the snow and ice, I feel a little confused.

She thought, it would be nice to have a smart assistant that could give her timely reminders.

With this in mind, she raised the cutting gun in her hand and started cutting the steel plate.

Amidst the flying sparks and piercing sounds, Song Haitao and Sun Jingtao turned around at the same time.

Although these steel plates are thick, their hardness and strength are affected to a certain extent due to being in a low-temperature environment for too long.

With Jiang Yan's cutting gun, although it was not as easy as cutting tofu, it was not that difficult either.

Soon, a rectangular door was cut out.
She pushed her palm forward gently, "bang!" The steel plate fell to the ground, and a bright room appeared before her eyes.

"This!!!" Song Haitao turned around and looked at the scene in front of him. He was surprised at first, and then delighted. "We are saved!"

Sun Jingtao had used a cutting gun before, so he was not as shocked as him. However, he was still surprised for a while after seeing the bright lights in the house.

"There are lights here, and it feels quite warm."

"These warehouses are generally equipped with dual-circuit power supply and backup high-power diesel generators to ensure power supply in special circumstances. If there are no special circumstances, there will be no problem in persisting for a few years." Song Haitao said, and then said:
"As for the warmth you mentioned, the storage environment of the seed bank is generally minus 20 degrees Celsius. The room temperature is minus 50 to 60 degrees Celsius, so when we come in, it is equivalent to entering a high temperature environment."

"This reminds me of when you go to the north to drink beer in winter, the boss asks you whether you want room temperature or refrigerated beer, and you insist on saying refrigerated." Sun Jingtao suddenly remembered a joke.

Jiang Yan, who is from the south, was puzzled. "Why?"

"Because, in the north in winter, the refrigerator is refrigerated at minus six degrees Celsius, and the normal temperature outside is minus twenty degrees Celsius."

Jiang Yan laughed, "No wonder I used to watch videos. In winter, ice cream and other things were sold outdoors."

The three of them entered the room one after another. There were several locked doors inside.

However, these doors are child's play compared to the safe door outside.

Hua Bao solved the problem in no time.

Soon, storage racks filled with various seeds neatly arranged appeared in front of them.

"I am a little worried now. If these seeds leave this environment with suitable temperature, the germination rate may be affected." Song Haitao looked at the densely packed seeds and frowned again:
"But if we keep it here, there's a high probability that we won't be able to come back in the future."

No one can predict natural disasters.

It is not impossible that this land will be completely destroyed and turned into wasteland in the future (End of this chapter)
