Although he knew in his heart that it was a virtual world in the game, the fully immersive simulation still made Qi Lin's heart beat faster.

"This road shouldn't be that simple......"

As if to confirm what Qi Lin was thinking, just when Qi Lin had just marched into the middle of the entire corridor, the faint blue light suddenly changed, instantly turning into a dazzling blood red, and a buzzing sound from weak to strong also sounded in the corridor.

If it weren't for Qi Lin's big enough heart, otherwise, the moment the light changed color, I was afraid that the assault rifle in his hand would have gone off......

"Huh", two metal partitions that came out of nowhere blocked the space in front of and behind Qi Lin respectively, turning this metal corridor into a square column-shaped enclosed space two meters high, two meters wide, and ten meters long.

"I'll go! There's no mechanism at the door, waiting for me here! Qi Lin scolded secretly, and immediately kicked on the metal partition that fell in front of him, however, as a second-level evolutionary with a strength of up to 19 points, Qi Lin stepped down with all his strength, but nothing happened except for leaving a footprint on the metal partition.

According to the force of kicking back and the dull voice, Qi Lin's face suddenly turned ugly - the metal partition in front of him was probably no smaller than the round airtight door.

Although he didn't know how such a thick metal partition came out of the corridor without a single gap, there was no doubt that he had fallen into a trap, and with the power that Qi Lin possessed, he was afraid that he would not be able to break this trap through brute force.

Even if you can cut through the walls of the metal corridor, you will not be able to escape, you know, this is not on the ground, but in the rock formations dozens of meters underground.

"Can't get out...... It's just that the effect of this trap is to trap me here? Doesn't that make sense? If you want to take out the intruders, automatic fire control machine guns, strong acids, poison gas, ...... It's much more effective than that......"

Qi Lin was still frowning and thinking about a way to get out, and at this moment, the dazzling red light that had been refracting back and forth in the metal tunnel suddenly converged in front of him, forming a virtual projection in the shape of a Rubik's cube.

"What is this?"

Qi Lin was stunned for a moment, and was about to stretch out his hand to the Rubik's Cube projection, when a mechanical voice suddenly sounded in the corridor.

"Welcome to Base 404."

"404 base? What is that? Qi Lin asked subconsciously.

However, the voice did not answer Qi Lin, but said to himself: "It has been detected that the intruder is carrying a gray card...... Invincibility of the intruder...... External environment judgment ...... Time is being calculated...... It's 27,451 hours, 57 minutes, and 11 seconds post-war...... Rubik's Cube system, restarting the ......"

After the mechanical voice said a bunch of words that made Qi Lin confused, it suddenly fell silent, as if it had just appeared suddenly and then disappeared suddenly, except that the red laser cube projection in front of him slowly turned into a chessboard similar to chess.

In the sky above the chessboard, a text appeared in Chinese and English at the same time: "Please crack the chess game, remaining time: 120 minutes." ”

“…… Play chess? ”

Qi Lin was a little dumbfounded, could it be that this Yongdao trapped himself here, is it because of this 404 base's mastermind AI has been idle for more than three years, too lonely, and wants to find someone to play chess with it? ?

But...... Let's play chess, but the problem is ...... This kind of chess, Qi Lin has never heard of it, he has never heard of it!

It is not the traditional Chinese chess, military chess, and Go, nor the shogi of Dongying, or the chess of the West, nor the entertainment chess of flying chess or beast chess...... The chess in front of him is a brand new chess game that Qi Lin has never seen before!

On a checkered board similar to chess, each square is filled with pieces, except for an empty square in the corner of the board.

"Excuse me, what are the rules of this kind of chess...... What is it? Qi Lin spoke up, but did not receive any response.

"Hey, that's shameless, isn't it? I don't even know the rules, how do I solve this game? ”

Still no response...... It's just that Qi Lin seems to feel that the space of the corridor seems to have become a little smaller......

"Grass...... Isn't that ......?"

Qi Lin stared at the corner where the wall and the ground of the corridor met for five minutes, and finally confirmed a terrifying guess in his heart: the walls, floor, and ceiling of the corridor were constantly shrinking inward!

At this level of reduction, after two hours, the space would disappear completely, and Qi Lin in the middle of it would be squeezed into a puddle of fleshy mud......

No, Qi Lin may have less than two hours left, and after two hours, the space will disappear completely, and there is no need to wait until then, as long as Qi Lin can't bear the space that is getting smaller and smaller, he will be squeezed to death!

"I'm ......!"

After recognizing the reality, Qi Lin had to force himself to calm down, and then sat cross-legged in front of the laser-projected chessboard.

Glancing at the space in the corner of the chessboard, Qi Lin tried to reach out and pinched a chess piece that was located on the edge of the space and was projected by a laser.

Qi Lin raised the hand holding the chess piece a few centimeters, and the virtual chess piece was also raised, but when Qi Lin wanted to drop it on the space, he was depressed to find that this time, the chess piece was not obedient at all, no matter how many times Qi Lin's hand fell on the piece, the chess piece was always hanging in the air and could not land on the space.

“…… Isn't that how you go? ”

Qi Lin moved the chess piece hanging in the air back to its original position, staring at the chessboard with his eyes fixed on it, holding his chin and thinking.

If the piece cannot be moved directly to the space next to it...... That's the rules of action for checkers?

In a different way of thinking, Qi Lin picked up another chess piece, and there was another chess piece between this chess piece and that empty grid, but when Qi Lin landed the chess piece on that empty space, the chess piece that was "skipped" disappeared directly from the chessboard!

"I see!"

Qi Lin tried a few more times, and found that the chess piece could cross a neighboring piece in a straight line and fall into the space, while the chess piece that was crossed disappeared directly, but no matter what, it could only cross one piece at a time.

Moreover, it can only be spanned vertically or horizontally, not diagonally.

Qi Lin kind of understands the gameplay of this game of chess, as long as he uses checkers to eliminate as many chess pieces on the board as possible, and when there is only the last chess piece left, it should mean that the game has been completely cracked!
