Guided by the white beam of light emitted by the bright flashlight, Xu Luo kept moving forward.

The passage is a little stuffy, and it seems that the air circulation is not very smooth.

After walking for about five minutes, another stone gate appeared in front of Xu Luo's eyes, but Xu Luo's face showed a touch of joy.

This distance is very close to Zhu Cheng's Taoist villa.

Sure enough, it's the same entrance.

Xu Luo had already made a decision in his heart.

The stone door didn't have much of a trick, and it quickly found the black button.

Pressing the button, the stone door slowly opened, and another passage appeared in front of me, but there was no musty smell.

Xu Luo understood that the passage he had just taken must have been blocked.

After entering the passage, he felt a breeze, and the ventilation facilities of this passage were obviously in good condition, but Xu Luo felt a faint smell of zombies.

After walking for less than fifty meters, there was an obvious stone gate on the left side of the passage, and the smell of zombies came from behind the stone gate.

Xu Luo stopped and sighed faintly.

If there is no miscalculation, this zombie smell is emitted by the zombies that Zhu Cheng's wife has become.

Without thinking too much about it, a map of the passage of the underpass came to mind.

It's not the one that Hu Ankang gave him.

Instead, in that blank portrait, I found a map of the underground passage on the white paper, which was far more detailed and accurate than the drawings given by Hu Ankang.

It's just that these two pictures are extremely disappointed by Xu Luo.

The drawings are all mutilated.

If Xu Luo is not mistaken, it is an incomplete treasure map.

In a word. The reason why Hu Ankang himself has not entered is that he has no way to enter the breakpoint marked at the end of the drawing.

Xu Luo was also unsure.

It's just that. In this case, he can only try.

The passage is neatly repaired. It doesn't look like some ancient depth, a sinister passage with countless mechanisms.

Aside from a slight twist, nothing thrilling happens.

A thought flashed through Xu Luo's heart.

This passage was only built by later generations to cover up the entrance to the dragon's lair.

Moreover, this practice definitely has a lot to do with his grandfather Xu Donghao.

He suddenly thought, if Zhu Cheng died, who would be sent here to take care of it? Zhang Quanhai? It shouldn't be, he's not one who wants to stay here all the time.

After constant speculation, we finally reached the end of the passage.

Another stone door appeared in front of me.

This place is the breaking point of the drawings given by Hu Ankang, and the drawings obtained from the blank portraits. There should also be a boxy room inside.

Xu Luo began to carefully examine the stone gate.

Completely different from the stone gate seen before, this stone gate has a chessboard, a nineteen-way Go chessboard.

There are only thirty-seven pieces on the board, black and white.

Each piece is the size of an egg.

Outside the chessboard, there are black and white pieces.

This is the beginning of a game of Go, and if you are not mistaken, the black and white pieces outside the board are the key to opening this stone door.

A grim smile appeared on Xu Luo's face.

His previous speculation should not be wrong, this passage must have been the handiwork of his grandfather Xu Donghao.

Just because Xu Donghao has taught him Go since he was a child, and at this beginning, Xu Donghao has let him practice countless times. Xu Luo didn't need to recall at all to know how the black and white chess pieces should be played.

Didn't pick up the black pieces that should have been played.

Xu Luo picked up the white chess that should have been played later, and put it in the center.

Then black is on a dead spot.

"Rumble" with a loud bang.

The stone door slowly moved to the left, and a boxy stone chamber appeared in front of me.

This should be the reason why Hu Ankang never went in. Who would have thought that the last two moves of this game of chess were the masterpieces of Xu Luoxiao after deliberately messing around.

And Xu Donghao deliberately placed such a game of chess here, indicating that only Xu Luo could enter this stone room, and others could only open the stone door unless they used violent means.

It's just that who knows what other means Xu Donghao has arranged.

Use violent words of destruction. Who can guarantee the existence of this stone chamber.

Xu Luo suddenly understood why Hu Ankang only gave him two hours, and it was estimated that Hu Ankang would not be able to open this stone door in two hours. Then Xu Luo's final result was also a failure.

There are no five fingers in the boxy stone room.

Under the illumination of the flashlight, there are no furnishings inside.

Not even a pebble could be found.

But what surprised Xu Luo was. The smell in the stone chamber is not unpleasant, and there is only one possibility.

This stone chamber is not hermetically sealed.

It's just that. In the empty stone room, without any lights, how could Xu Luo find the mechanism in the stone room.

His brow furrowed.

Strive to begin searching for memories of Xu Luo in this life.

All the memories were like a series of numeric codes running quickly, which was not a very difficult thing for Xu Luo's current mental power.

It's just that after all the memories have been searched through.

The answer was disappointing.

Clueless.

There is no trace of the arrangement of this stone chamber.

Time is slowly ticking.

Xu Luo, who had always been extremely calm, finally began to get agitated.

If he knew that this was the case, he should have found a way to talk to Xu Donghao on the phone first, and directly ask about the secret of this stone room.

However, the most important thing now is that after one out and one in, is it too late?

More importantly, how much time is left for Xu Luo to explore the rest of the Dragon's Lair Passage, which no one knows.

The left hand hangs down.

The white beam of the flashlight hit the floor of the stone chamber.

Xu Luo lowered his head in contemplation, and his eyes suddenly lit up.

There are numbers on the ground floor of the stone chamber.

Xu Luo squatted down and carefully surveyed the ground with a strong flashlight.

The extremely light boxy grid, not every grid has numbers, but there are numbers in the ten squares near Xu Luo's side.

Ten numbers, zero to nine.

This is supposed to be the mechanism that unlocks this stone chamber.

But what kind of number combination would it be? You know, there are endless variations in how these ten numbers are combined.

For Xu Luo, he can only find it from the people in the family.

Your own birthday? Grandpa's birthday? Paternal? Uncle and Uncle Three?

It seems possible.

Xu Luo walked through the numbers he had just thought, but there was no response, none of these numbers were a combination of numbers to open the stone chamber mechanism.

What other number combinations will there be?

If it is connected to the chessboard on the stone gate just now, this string of numbers must be related to him, but what other numbers are related to himself?

Xu Luo once again entered a state of sorrow. (To be continued......)
