So, if this door is really a technological creation, the designer cannot only design a recognition system for opening the door. According to the intelligent design, there must be manual operation. Su Yin began to fumble around.

Sure enough, I found a box button on the rock next to the door. When I pressed it, the box opened, revealing a combination lock and a lever underneath, but it couldn't be pulled. If you pull it forcefully, it would cause skin damage.

"Are you kidding?" Su Yin recalled the story of deciphering codes in his previous life as an agent. This code lock is an ordinary nine-digit code lock with four numbers on it. As long as you press the correct number, the code lock will be unlocked.

You can pull the lever and open the door.

Su Yin quickly found the logical thinking and began to decipher the code. However, after several attempts, it was obviously wrong, so he tried his best.

Sikong and Qingkong looked at Su Yin who was busy deciphering the code. Sikong, in particular, was shocked more than he had ever been in his life. He did not expect that he, who had read ancient books and thought he had deciphered the method to enter this place, would still be surprised.

It would be better for a girl who has no idea at all and can find the secret mechanism on her first visit.

For some reason, Sikong felt a feeling of jealousy in his heart. This was jealousy towards Su Yin.

The four-digit password is not complicated, but if you test it one by one according to the death method, it will be a huge workload. Su Yin is not sure whether the designer has set a self-destruction method. After she tries it a few times, she will

Automatically destroy, the more this happened, the more careful she became, but she failed to decipher it many times, so when she was a little tired, she pressed one, two, three, four at will.

"You're kidding me." There was a click, and a soft sound was heard from inside. This was a reminder that the combination lock was opened. You can now pull the operating lever to open the door.

Who knows how to use 1,234 as password?

Su Yin was speechless for a while, and couldn't bear to complain, so he pulled the operating lever hard.

With a click, a gap appeared in the metal door, and a small door opened. The door, which had been sealed with dust for who knows how long, was finally opened in front of Su Yin and the three of them. The secret hidden in this mysterious place was about to be revealed.

Su Yin was very excited.

She seemed to see a connection between this world and the technological world before her rebirth. This vague feeling of intimacy, as if she were back in her hometown, made her very excited. She opened the door and walked in first.

Seeing Su Yin open the door, Sikong was still a little in disbelief, but seeing the matter-of-fact look in Qingkong's eyes, he followed him through the door.

It was dark inside the door, filled with the smell of dust. Maybe it had not been opened for too many years, and no one had lived there. Su Yin turned on the flashlight, and there seemed to be debris everywhere, blocking the space, and he could not tell the difference.

Details and facilities here.

Su Yin made a cautious gesture towards Qingkong. In this mysterious facility, a little carelessness might lead to horrific consequences. Qingkong stood still behind her and started to look for the power supply to see if she could open it.

power supply.

As Su Yin fumbled for a while, he found the power source. Maybe it was a generator or something else. When he pressed the switch, the light came on after a brief period of power.

This so-called secret room, where the Human Emperor Sword is hidden, appeared in front of the three people.
