"Yes. This is one of the only three wild animal germplasm resource banks in the country. It is very important and special, so the protection level is much higher." Song Haitao walked forward and looked at the severely damaged steel door. He frowned:

"This is a high-level protection door used in the bank's underground vault. Generally, it requires the fingerprint recognition, retinal scanning and password triple verification of the authorized person to open it. Now it is all destroyed. How to open it is a problem."

Sun Jingtao suddenly had an idea, "Why not let Jiang Ye try. Isn't he the most powerful hacker?"

Song Haitao shook his head, "Even if he comes, he can only crack the password at most. The fingerprint and retinal issues are also unsolvable."

Jiang Yan didn't say anything and secretly let Huabao go.

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

Hua Bao, who suffered a setback for the first time, curled her lips and said, "Mom, this place is airtight and I can't sneak in."

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

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

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

After he said that, he took the emergency light from Jiang Yan and checked along the wall little by little.

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

"Those are all kept and stored by the government, and I have the authorization for most of the access control. However, we will also face some special situations, similar to-" Song Haitao paused, turned his head habitually to look around, and then continued:

"After the extreme cold weather, we will face global oceanization. Except for a small number of materials stored in the mountains, most of the materials were left in some underground warehouses because there was no time to transfer them at that time."

Sun Jingtao reacted quickly and continued, "Does that mean we have to go to the bottom of the sea?"

Song Haitao nodded, "You can understand it this way, it is 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. So 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 teaming up to rob a tomb." Sun Jingtao was not scared by the difficulties, but there was a hint of excitement and expectation on his face.

Song Haitao's face became serious. "Xiao Sun, although your analogy is a bit inappropriate, the treasures obtained from tomb robbery are too small compared to the national treasures."

"Doctor, how about we go upstairs and see if we can find a gap from the roof?" 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 little dust.

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

"No wonder those people have been struggling at the door for so long and still got nothing. However, the main reason is that they lack powerful weapons." After Sun Jingtao finished speaking, he looked at Jiang Yan, "Jiang Yan, how about trying with a heavy machine gun?"

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

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

After all, 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 didn't say it, I would have forgotten it."

She took off her backpack and took out the plasma cutting gun from it.

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

"Doctor, Brother Tao, put this on." Jiang Yan handed two pairs of soundproofing headsets to the two of them, and put on one herself.

Song Haitao's eyes flashed with shock, "Jiang Yan, you must take good care of this backpack."

"Yes, Doctor, I will." Jiang Yan said, took out a pair of protective sunglasses and put them on, holding the cutting gun and walked towards the steel door.

"There is 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.

Especially today, after rushing for half a day in the ice and snow, she felt that her brain was a little unclear.

She thought, if there is an intelligent assistant who can remind her in time, it would be great.

With this thought, she raised the cutting gun in her hand and cut the steel plate.

Amidst the sparks, a harsh sound rang out, and Song Haitao and Sun Jingtao turned around at the same time.

Although these steel plates are thick, their hardness and strength are still affected by being in a low temperature environment for too long.

Under Jiang Yan's cutting gun, although it is not as easy as cutting tofu, it is not that difficult.

Soon, a rectangular door was cut out, and

she gently pushed forward with her palm, "Bang!" The steel plate fell to the ground, and a bright room appeared in front of her.

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

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

"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 under special circumstances. If there are no special circumstances, there will be no problem in persisting for a few years." Song Haitao finished speaking, and then said:

"As for the warmth you mentioned, the storage environment of the seed bank is generally minus 20 degrees. The room temperature is minus 50 to 60 degrees, so when we come in, it is equivalent to entering a high temperature environment."

"This reminds me of going to the north to drink beer in winter, the boss asks you whether you want room temperature or refrigerated, you must say refrigerated." Sun Jingtao suddenly remembered a cold joke.

As a southerner, Jiang Yan 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, those ice creams and other things were sold outdoors."

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

However, compared with the vault door outside, these doors are simply child's play.

Hua Bao solved it in a few moves.

Soon, storage racks with various kinds of seeds neatly placed appeared in front of them.

"I'm a little worried now. If these seeds leave such a temperature-appropriate environment, the germination rate may be affected." Song Haitao looked at the densely packed seeds and frowned again:

"But if they are kept here, there is a high probability that we will never be able to come again in the future."

No one can say for sure about natural disasters.

It is not impossible for this land to be completely destroyed and turned into wasteland in the future (end of this chapter)
