Back on the shore, Hans began to ask Sheila, "The water pressure down there is too much, I wonder if we can turn all the water into ice, and then open a passage to go down?"

Before Sheila could reply, Alpha said, "This will not work, if you turn this place into ice, I don't know what will happen to the Tree of Life, which is the foundation of the Shadow Song Forest and cannot be damaged." ”

"You said there's an ancient ruin down there, isn't that underwater?

"There is air, I don't know why this is happening, at a depth of more than 100 meters, there is a passage, and after walking through the passage, you can return to the water. ”

Hans frowned and said, "That's strange, you mean that the water level inside is different from here, and it stands to reason that the water surface on both sides should be in a balanced position, unless, the space inside is closed and the air cannot be discharged, but this will cause the air pressure inside to be very large." ”

"We've been down before, but the air pressure you talked about doesn't seem to feel any different from here, and I don't know why. ”

"It's not necessary to go if it's too dangerous," Sheila said. ”

Hans said, "I'll think about it again, maybe there's a secret of how the Shadow Song Forest came to be." ”

Hans pondered for a while, he began to emit the fire of the black wolf, and then condensed a small magic circle around him, and let this magic circle move with him, which should be able to support the consumption of continuous use of wind shields underwater.

Then, Hans also condensed two stone locks, one in each hand, opened a ring-shaped wind shield and jumped into the water!

It worked, and the weight of the stone lock was a little more than the buoyancy of the wind shield, and he began to slowly sink down.

Every time he falls a little distance, he increases the stone lock a little more, so that he can control the buoyancy of the stone lock by controlling the size of the stone lock. And because of the storage of the Restoration Magic Array, he can always maintain the wind shield against the water pressure, but the deeper the place, the greater the water pressure, and his consumption has also begun to increase, if he can't reach the destination faster, it is possible that this Restoration Magic Array will not be able to hold on to his consumption.

But it didn't take long for him to reach the bottom, and in the pitch darkness, Hans followed the direction of Bercy's illumination magic, which was a horizontal passageway, and as he walked forward, he noticed a strange thing, in this relatively balanced passage, the further he went, the less the water pressure became.

After walking about two hundred meters, Bessie began to walk upward. Hans also shrunk the size of the stone lock, and began to float up to it, and in a few moments it was out of the water.

He jumped ashore and felt that the air pressure here was no different from that on the ground, and the air was fresh, just like in the forest.

Ignoring him for a moment on something he couldn't figure out, Hans turned on a lighting spell and looked at his surroundings.

It's still a stone cave just near the water, but as you keep going, you find that it's an underground base.

Alpha and Bessie didn't bother Hans, and let him observe everywhere, the ancient ruins in the eyes of the elves turned out to be really the technological products of the ancient earth era.

Unlike the underground real yàn room that Hans found in the Marin Snow Mountain, it is quite well preserved, and some real yàn instruments can be found in many rooms, but due to the long time, those instruments are basically unusable, and even some more sophisticated machines are broken when touched.

Hans found a book in front of an instrument, but he didn't dare touch the bare book, and it was probably something that would break if he touched it.

Hans said to Alpha, "This is supposed to be a book, is there a way to remove the pages from the surface without destroying him?"

Alpha said: "It should be possible, but the pages in the book usually have two sides, take the front page, and the back will not have a chance to see it." ”

"That's no way, it's better to be able to read part of the content than not to be able to open it. ”

Bessie said, "Wait until I try it." ”

Bessie walked over to the book, then waved her staff and began to cast a spell.

I saw a small magic array condensed above the book, and then the book began to peel off a little bit, and the fragments were sucked into the magic array.

The book was peeled off evenly, until the time it was time to discover the text, and Bessie stopped.

When Hans saw it, it turned out to be the instruction manual of a device called "Microbial Accelerated Incubator".

He told Bessie to scroll down to see if there was anything valuable.

Under Bessie's magic, another page was peeled off of the book, and Hans suddenly shouted, "Stop!"

Hans screamed at close range, blowing some of the pages apart. However, a signature still came into his eyes, "Tang Qiang". It's that biologist Tang Qiang, could it be that this is his real room?

Hans told Bessie to continue scrolling, but after many pages in a row, he found no useful clues.

At this point, Alpha said to Hans, "There are many things here that are easy to break, but there is one place that is peculiar, it seems to be a room, but we have tried many times and have not been able to open the door. ”

"Where?"

"I'll take you to see it. ”

Hans then followed Alpha to a room, where there was a door, and traces of the door being attacked.

It's not that there are marks on the door, but that the original walls around the door are broken, revealing the metal structure inside, and it feels like it's a small house made of thick metal, and there is an old mechanical combination lock on the door.

A thought crossed Hans's head: "This is the vault?"

Hans touched the switch of the combination lock, and the vault, along with the switch, was made entirely of some special alloy, which was so hard even if all the other equipment was broken.

It seems that in order to prevent hacker incursion, the mechanical password lock was chosen, although I could think that this might be Tang Qiang's thing, but I don't know this person, how can I guess his password?

This is an eight-digit digital password lock, since Tang Qiang and his father are good friends, then try it on his father's birthday.

After the defeat, Hans thought that many people should know about their friendship, and it was normal not to use this password, but it would be even more difficult if he used a password that had nothing to do with people.

With the idea that it would be okay to try, Hans tried his own birthday and his brother's birthday in succession, but to no avail.

Hans held his head and pondered for a while, and his mother's birthday was not tried, April 3rd, but what year was it? He had no memory of it, but remembered that there would be a memorial every year on April 3rd.

I was born in 2020, so let's push forward 20 years and keep trying, anyway, I didn't say that failure would explode.

Since 2000, 1999 and 1998 have tried like this, but it was not until 1988 that the door suddenly clicked and opened!
