Now he didn't know the password, Shangguan Yu carefully studied this air corridor, he counted, and went to the front cabinet There are 13 rows of floor tiles, and each row has a total of three floor tiles, so there are 39 in total.

If the trigger conditions are determined based on the route, then it can be judged that one or two floor tiles in each row are safe. There must be a safety tile in this row that is connected to one of the safety tiles in the next row in a straight line, not diagonally.

Shangguan began to explain his reasoning: "You see, these 13 rows of floor tiles, we will number them, the row in front of 01, and so on, the last row is 13, which of you will remember it." ”

Spice took a pen and paper and began to draw and record.

Shangguan Yu continued, "From left to right, these three bricks are ABC. As you saw just now, I threw the zombie to the location of 02B, and the route I threw passed through 01A, so 01A, 02A, and 02B can be determined to be safe, while 01B is dangerous, and 01C and 02C cannot be determined. ”

"Wait a minute, Brother Yu," Zhao still pointed to the first floor tile on the left side of the second row and said, "That 02A, how can you be sure that it is safe, and you didn't pass through there." ”

Shangguan Yu smiled and stepped over.

"Ah......" Zhao still screamed in fright, she didn't want to see Shangguan Yu split in half by the light curtain, and Sena and the others were also so frightened that they held their breath.

"It's okay, trust me!" Shangguan said that, he was already standing on 01A, and put his foot on 02A, and nothing happened.

"See," Shangguan said, already standing on 02A, and continued to walk to 02B, where the zombie corpse was.

"Okay then, what's next?" Senna asked, clasping her hands over her shoulders.

Shangguan Yu said: "According to my speculation just now, since 02A and 02B are safe, then 02C is dangerous. ”

Senna asked again, "yes, what's next?" With these three bricks in row 03, you can't tell which one is good and which one is bad. ”

"Then it's just guessing."

"Guess? Brother Yu, are you crazy? Sena asked, and Zhao still shouted: "If you guess wrong, you will die!" ”

Shangguan Yu retreated from the original path, walked out of the patio, and searched outside.

"Looking for what?" Both girls asked.

There was an iron pipe more than a meter long not far away, and Shangguan Yu walked over and picked it up. He walked back with an iron pipe, and everyone understood what he meant, he was going to use the iron pipe to test it, although it was a good way, but it did not deny that there was a certain risk.

Zhao still asked worriedly, "Can this work?" ”

"At present, it can only be like this, I don't know the password, so I can only give it a try."

Shangguan Yu took the iron pipe to the position of 02B, took a deep breath, and put the vertical iron pipe horizontally towards 03B close to the front.

"Brother Yu," Zhao still shouted nervously, clenching the hand of Sena beside him, who was also very nervous.

The iron pipe stretched out to the top of 03B, and in the next second, he saw a light curtain flashing, and then he heard a bang, and the iron pipe in Shangguan Yu's hand was broken into two sections, one was still in his hand, and the other had fallen to the ground.

The light curtain flashed in front of Shangguan Yu, and then disappeared, and Shangguan Yu could feel a hot breath coming from his face.

The two girls in the back screamed in fright, and the two soldiers and Spice were also frightened.

"Brother Yu, Shangguan Yu!" Zhao still shouted in the back.

Shangguan Yu didn't say anything for a long time, and Zhao was still about to rush up, but was stopped by Sena.

Shangguan Yu stretched out his hand and made a "V" gesture in the air.

Zhao still said in the back, "Shangguan Yu, you scared me to death!" ”

Shangguan Yu didn't answer, and began to concentrate on the next step of judgment. 03B is a trap, so according to your own guess, 03A should be good.

Although it was such a guess, Shangguan Yu still didn't dare to go over in person, he felt that it was better to test it.

So he stretched the iron pipe to 03A again, and sure enough, there was no response, indicating that his guess was correct.

Shangguan Yu came to 03A and began to continue the next step of the test, first test 04A, it is good, since it is good, go over first, so Shangguan Yu stood on 04A again.

As for 04B and 04C, which one is a trap, it can't be deduced now, so I can only continue to test the fifth row, first test the first tile in the fifth row, which is 05A.

Shangguan Yu stretched the iron pipe to the front tile, and it was a good one.

Then he should set foot in 05A, he stood up, turned around, and said to the people behind him, "So, isn't everything OK?" ”

Zhao Yi and Sena were about to step on Shangguan Yu's footprints and come over, but they were stopped and said, "Don't come here, when I am all done and arrive at the opposite side safely, you will come again!" ”

Just as Shangguan Yu was about to continue to step into the sixth row, suddenly, he saw a blue light light above the patio at three o'clock on the right, and a light curtain was drawn down, at a speed visible to the naked eye.

Zhao was still scared and screamed, and Shangguan Yu was also confused, why did this "bad girl" suddenly not play according to the rules of the game?

Shangguan Yu stood in place and did not dare to move, and from the position where the light curtain appeared, it could be judged that it would cross the sixth row.

Shangguan Yu asked, "Spas, what's going on?" ”

Spice spread his hands and said, "I don't know!" ”

"What should I do next?" Shangguan Yu asked.

Just as he was asking, the light curtain had already crossed in front of his eyes, carrying with it the scorching heat from the pavement.

The light curtain did not disappear immediately, and after crossing the direction of nine o'clock on the left, it returned and changed direction, heading towards the fifth row, which was the one where Shangguan Yu was.

At the same time, in the direction of three o'clock, another light curtain lit up, and quickly crossed from the fourth row, and it was constantly swiping left and right.

This means that the fourth row cannot be returned, and the light curtain of the fifth row is rapidly approaching, which means that Shangguan Yu must immediately make the decision to go to the sixth row and settle on the first few bricks.

"Brother Yu!" The two girls, Zhao Yi and Xena, exclaimed, and their hearts rose to their throats.

If he doesn't make a decision, he will be cut in two by the approaching light curtain! Although he Shangguan Yu is now very bad in all aspects, he doesn't dare to guarantee that his physical body can resist this domineering and incomparable light curtain at that time.

Seeing that the light curtain was about to approach, Shangguan Yu immediately picked up the iron pipe and tested it on the 06A in the sixth row, and a light curtain cut down, cutting off the iron pipe, and with a bang, the broken part fell to the ground.

Shangguan Yu planned to test 06B again, but the iron pipe in his hand was already very short and could not reach the right position.

"Brother Yu!"

The sixth row can't be detected, and the light curtain in the fifth row has already arrived, if you don't make a decision, the consequences will be unimaginable!

"Ah, I'm fighting!" Shangguan Yu raised his feet and was about to step on 06B.

"Brother Yu!"

"No!" Shangguan Yu is really not sure, I can't bet my young life on it, so ......

Shangguan Yu turned sideways......
