Under the pressure of He Meng, who became Chong Du, the guards guarding the underground maze followed Yang Yu's command and conducted a guide to the ninth floor in an orderly manner.

On the way, Yang Yu mastered the ninth level one rule after another.

For example, if you keep pressing the square on the red box, there will be no forced displacement.

After stepping on the first red box, Yang Yu and the others started the timing. A few minutes before forced displacement occurred, Yang Yu asked everyone to withdraw from the chessboard. As a result, the blocks on the chessboard remained motionless and everything remained the same.

After confirming safety, Yang Yu led the team back to the chessboard and continued the previous strategy.

In fact, before evacuating, Yang Yu found that his first assumption was correct.

The first one found the red box emitted a dim light, and the second one was a little brighter than the first one.

But this is not because the number of red boxes has increased, but because the red boxes are exposed to the air.

In order to verify his conjecture, Yang Yu did several experiments.

For example, when encountering a grid that kills monsters, ask the guards who push the block to stop on the spot and ask the other guards to find grids that can summon monsters and stop them separately. After five or six grids with fixed positions, Yang Yu asked another person to push a red box away.

The newly opened red box is only a little brighter than the previous one, and it has not become brighter because of the larger number.

As the red box continues to be exposed to the air, the box becomes brighter and brighter.

Pushing open a red box will reveal that the brightness of the two red boxes is the same.

Whether a forced movement will occur is not determined by one box, but by all boxes.

After knowing this, Yang Yu quickly adjusted his strategy, first someone pushed to stop the blocks on different paths one by one, and found the first red box on the path. Then, Yang Yu used the blocks without red boxes on the moving path as a pathfinder, and conducted a detection on areas where the path had not been explored.

If you encounter a monster call point, stop and do not reveal the red box below. If you do not encounter a monster call point, keep the square relatively independent so that you can fill the possible red box in the new unknown area.

Adjusting some strategies will reduce the speed of the strategy, but it is safer.

Fortunately, the monsters that were brushed out were not strong, and the location was pseudo-random. They brushed three at a certain rhythm on the five other blocks closest to the pusher.

Yang Yu's strategy is to push it one by one, which leads to at most three monsters being produced each time.

With Bai Jin and the others' current strength, even if Yang Yu doesn't take action, he can easily clean up the monsters.

If you want to blame, you will blame the underground maze monster level for only one hundred, and the average attribute is rarely more than two thousand. Only the guardians of each level may have a little difficulty.

But then again, why can ordinary underground maze monsters only reach level 100?

Yang Yu remembered that his current stage was overload level. Although he did not redeem the answers about the overload level in the dragon and did not know what the overload level represents, Yang Yu vaguely felt that ordinary underground maze monsters could not enter the overload level and had only reached the top of the level 100.

The strategy was carried out in an orderly manner, with countless scattered scattered cubes, one after another, and the cubes became increasingly difficult to move.

Yang Yu once again asked Bai Jin to fly into the sky to draw a situation map.

Before they knew it, they arrived at the final stage of scheming the board.

The blocks are wound into an irregular closed pattern. As long as all the red boxes inside are found and filled, they should be able to pass the level.

At this point, you must be careful in every step next. Once the block is pushed into a blind spot, you have to start over. Moreover, when moving certain blocks, the red box will inevitably be exposed. When the red glow becomes brighter to a certain extent, a strong movement will occur, which will also waste all previous efforts and may even make people pay the price of their lives.

Yang Yu took the picture drawn by Bai Jin, sat on the block and fell into thinking, constantly making plans.

In the end, Yang Yu numbered all the peripheral blocks, let everyone stand on the edge of different blocks, and recorded the position where each of them was.

Then, Yang Yu stood in front of a block and opened his voice, his sonorous and powerful voice echoed in the space:

"Thank you all, and finally this moment, success or failure is here.

None of you wants to waste your efforts, and then do it again?

Then listen to my instructions and execute my orders seriously."

Others made loud noises one after another. After a long period of joint struggle, their hearts were completely twisted together. They were extremely eager to successfully defeat the ninth level, and at the same time they were extremely afraid of failure and would be unable to bear it mentally.

"I'm going to start, please hold your breath and listen to every command of mine."

Yang Yu said as he pushed the huge block in front of him.

Bai Jin, Oias, and Loloth sat on his block, ready to face the challenge at any time.

Lotkar turned into a giant wolf and wandered around Yang Yu.

Yang Yu pushed the block very quickly, which would inevitably cause countless monsters to refresh from the block. If Yang Yu was affected by several fish that had escaped the net, his speed would slow down and his strategy would also be affected.

Therefore, Lotkar, who has thick skin and flesh, must stay by Yang Yu's side and clear out the fish that have missed the net.

Lotkar stayed by Yang Yu's side. When others pushed the blocks to evoke monsters, Bai Jin and the others could also give priority to the fire to solve the problem, protecting the safety of others, and not worrying about Yang Yu's safety.

As for He Meng, in order not to expose his identity, Yang Yu specially used the excuse of "he is injured and cannot fight at will" to let her stand aside to supervise the battle, allowing He Meng to taste the taste of the melon for a long time.

With his palms fitting into the square plane, Yang Yu pushed the square in front of him into the closed area bit by bit.

When you reach the red box, you will feel blocked for two or three seconds, but Yang Yu completely disagreed and continued to push his blocks to quickly find out where the red box is.

After determining the location of the red box, Yang Yu immediately arranged personnel to push other blocks to fill and shrink inward.

In the empty area outside, Yang Yu and others placed the blocks where they wanted, and immediately asked the person to fill them with the activity blocks.

As Yang Yu quickly discovered the location of the red box, a large number of monsters surged out from different blocks.
