Lu Yuan and Xiao Shan continued diving underwater.
When one's feet are on the ground of the fortress.
Lu Yuancai finally got a clear look at the city that had been submerged by the flood.
The water was covered with murky mud, and every time Lu Yuan swung his flippers, the nearby water became even more murky.
Lu Yuan carefully determined his location, then pointed to a building in the distance that was half-submerged by water.
Xiao Shan nodded immediately, and the two swam towards the building.
The place Lu Yuan was referring to was Chen Yan's previous biological laboratory, which contained many animal embryonic stem cells and various plant seeds for research.
However, after Lu Yuan resigned, he was not very aware of the changes here.
The two swam towards the building, and soon they arrived in front of it.
However, just as Lu Yuan was about to enter the laboratory, he was suddenly stopped by Xiao Shan.
Lu Yuan quickly glanced at the other person.
Through Xiaoshan's diving mask, it was clear that her complexion looked a little off.
They seemed very tense and worried.
So, Lu Yuan looked in the direction the other person was pointing and saw that there were more than a dozen people underwater retrieving things in front of the building in the distance.
The diving suits they were wearing looked like the same ones they had produced when they were in charge of the fortress.
These diving suits are of very good quality, made from special silk, with a soft fabric and good water-repellent properties.
More importantly, at depths of about ten or twenty meters, the water pressure is very high and the temperature is very low.
This type of clothing can withstand underwater water pressure if a protective shell is added to the chest area.
When Lu Yuan saw these people, he had a feeling that they were definitely not ordinary refugees.
After all, there aren't many people in the fortress who have diving suits.
These people were all wearing diving suits, clearly indicating they were from important departments within the fortress.
Then, Lu Yuan pointed to a spot in front of a building in the distance.
Xiao Shan immediately understood what Lu Yuan meant.
So the two swam toward a corner of the building.
This place wasn't far from those people in the distance. Although it was impossible to speak underwater, Lu Yuan wanted to see what these people were doing there.
So the two of them quietly hid in a corner and watched these people busy at work.
Several people were seen shining their flashlights at one spot.
The remaining men, each holding a pair of iron chains, dragged the chain to the wall of a laboratory.
Next, the group found various tools and secured the ropes to the wall.
After it was secured, someone reached out and tugged at the rope in their hand, as if there were other people waiting above.
The rope was quickly taut, and then the group of people moved away into the distance.
Even from a distance, Lu Yuan instantly understood what these people were up to.
These people dived to such depths in order to gain access to the laboratory.
However, the protection level in the laboratory is extremely high, and without certain skills and tools, it is simply impossible to enter the laboratory.
Immediately afterwards, Lu Yuan saw the wall in the distance suddenly collapse, and a large amount of mud made all the water nearby muddy.
Seeing this opportunity, Lu Yuan immediately nodded to Xiao Shan.
The two swam quickly toward the gate.
When Lu Yuan designed this laboratory, he had already explained to Lu Yuan how to unlock the main door.
Several hybrid unlocking methods are used here. The first is fingerprint and facial recognition unlocking, which has the highest security level.
However, the area is now flooded and without power, the fingerprint and facial recognition unlocking devices are unusable.
The second method is swiping a card. Of course, this method of power control can no longer be used.
Another method is the oldest way of picking locks, but to ensure the safety of the laboratory, they deliberately hid the lock very deep inside.
Very few people know where the lock is hidden; only the person who designed the laboratory knows.
Lu Yuan led Xiao Shan to the side and began counting the bricks on the wall.
Lu Yuan quickly located the lock, then took out an axe from his waist and smashed it hard against the wall.
One, two, and soon the bricks were smashed into pieces. After Lu Yuan sifted through the debris, he immediately discovered the lock inside.
So, Lu Yuan took out a key and inserted it directly into the lock.
With a "click," the lock was opened.
The lock that Lu Yuan had was something that Jock had specially asked his friend to get for Lu Yuan back when they were in the underground fortress.
This key can open about 80 percent of the locks on the market.
Of course, these are just common locks; you can forget about locks like those used in bank safes.
After the door opened, Lu Yuan and Xiao Shan tiptoed inside.
To avoid being discovered, Lu Yuan and Xiao Shan turned the lights down very low.
Continuing along the dark corridor, the laboratory was eerie and sent chills down my spine.
Once Lu Yuan was certain that they wouldn't be discovered, he quickly led Xiao Shan towards the seed warehouse.
