How to break into a math book

A flash of inspiration suddenly flashed in Tu Hua's head. It turned out that this numerical problem of finding patterns was the same as the previous ones, and needed to find another way.

The first line is a number [1], and the second line is [11]. The two 1s in the second line are not a continuation of a certain law, but a description of the number in the first line.

The two 1s in the second line, the first 1 represents the quantity, and the second represents the content.

In other words, the real meaning of [11] in the second line is to describe the number in the first line: one 1.

According to this rule, the number [21] in the third row makes sense, which means that the number [11] in the second row is two 2s.

那么第四行数字的【1211】则是按顺序描述第三行的两个数字：1个2和1个1,正巧就凑成了1211。

第五行则是在描述第四行的数字,1个1、1个2、2个1正好就凑成了【111221】。

所以他要填的第六行的数字应该描述第五行的内容,按照顺序应该是：3个1，2个2和1个1。

Combined and written as numbers, it is [312211].These numbers are not some ready-made rules, but the description and statistics of the previous row of numbers.

The light in the trap was still dim, but Tu Hua's eyesight had gradually adapted. He quickly picked up a stone from the ground, brushed away the moss attached to the wall, and wrote the answer under the five rows of numbers.

Although the sound of stones sliding on the wall was faint, it was actually a bit harsh in this quiet environment.The second after Tu Hua finished his answer, cracks suddenly appeared on the originally solid wall, as if the whole earth shook.

Su Gechi quickly pulled Tu Hua behind him, and the two hid in the corner, watching the changes in the wall in front of them.

The wall did not collapse as expected, but instead formed a cavity as tall as a person. The hole seemed to be a long tunnel leading to the outside of the trap.

Sure enough, there is an exit!

When the shaking stopped, the two quickly got out from the hole.After passing through an uphill tunnel more than 100 meters long, Tu Hua finally saw the light and they came out.

This exit is on the hillside next to the Tyrannosaurus rex just killed, just overlooking all the scenery below the mountain.Standing here and taking a look, I realized how poorly the trap master who let Tu Hua fall into the trick was. The fallen leaves placed at the trap were obviously different in color from the fallen leaves next to them.

Tu Hua was about to find the trap master and kill him, but although he found that he had already left the trap, he and Su Gechi never let go of their clasped hands.

His blood volume had already reached full point, Tu Hua looked up at Su Gechi, and found that he was also looking at him.At this time, what came from his palm was not the energy in the game, but the sense of security of companionship and protection.

Tu Hua secretly thought, if only he never let go.

But Su Gechi suddenly took his hand away, and then the hand that had been transmitting energy to him suddenly touched his cheek. Su Gechi had a green skin on his face, his eyes were hesitant to speak, and he said in a low voice : "You look at me like that, it makes me want to commit a crime."

Tu Hua quickly realized what he meant by "crime". After blushing for a while, he said, "I'm an adult, you are not considered a crime."

Hearing his words, Su Gechi smiled lightly and rubbed his hair: "It seems that you are looking forward to it."

Tuhua's face turned even redder.

Fortunately, Su Gechi didn't tease him any more, and pointed down the hillside and said, "The trap master who set the trap is right there."

Tu Hua looked in the direction of his finger, and sure enough, he saw a crooked man hiding behind a tree with his waist bent, his eyes darting all over the place.

Regardless of whether it was the trap master who framed him or not, this person is also an enemy anyway.Tu Hua took out his gun. His marksmanship was extremely accurate. The moment the trap master probed his head, he shot his head with a "bang."

The trap master is eliminated directly.

Tu Hua checked the number of people in the checkpoint. He had already killed 3 people, the gunman at the beginning, the Tyrannosaurus rex, and the trap master just now, and the others were also fighting at the same time.There were originally 100 people in the checkpoint, but now there are only more than 30 people left.

Tu Hua is ready to launch a blanket search and launch an attack.The high ground he has occupied now, the hillside is very suitable for the gunman to hide and snipe.So he followed the crevice of this hillside to other places on the island that he had never been to.

About half an hour passed, and Tu Hua killed 2 healers and 1 invisible man during the search process. He killed 6 people in total, and there are still 4 challengers left in the level.And the hill where he is currently crawling has just had a fierce gun battle, in which a Tyrannosaurus rex, a gunman and a healer were killed.

Tu Hua hadn't made a move just now. On the one hand, he was afraid of revealing his position, and on the other hand, he was observing the positions of others.

The winner of the scuffle just now was obviously the gunman. According to Tu Hua's observation, there was a gunman ambushing in his southeast direction and due west direction respectively.

Counting him in the game, there are still 4 people left, but he has never found out who the last remaining person is.

Tu Hua hid in the grass, covered with leaves, and Su Gechi lay beside him. His green skin was hidden in the grass, making it difficult to be found.

He was sure that the other three were also looking for each other, and they had to find out where everyone else was before they could find a way to make a move.

Tu Hua squinted his eyes and searched, and finally there were only four people left, but the fourth person was never found. There was only one possibility—he was an invisible person who was good at hiding.

The invisible man does not mean that his body can disappear, but that he can become the same color as the surrounding scenery and become homogeneous with the environment.So he is not impossible to find, as long as you observe carefully, you can detect the outline of his body.

Sure enough, Tu Hua's prediction was correct, the fourth person was an invisible person.

And he happened to be lying on a branch just to the northeast of Tuhua, one part of his body turned into the color of the leaves, and the other part turned into the color of the trunk. If it weren't for the branches shaking for no reason, Tuhua wouldn't have been able to found him.

Tu Hua didn't want to make a move at first, and wanted to strike late at this time, but the invisible man lying on the tree obviously saw Tu Hua, holding a hidden weapon in his hand, and was moving forward bit by bit.

So he had to make a move.

Tu Hua looked at the right time, one of the other two gunmen hid in the due west direction, and the other hid in the southeast direction, so as long as he quickly moved behind the tree in the northeast direction, the two gunmen would not find him.

Tu Hua skillfully and slowly moved his body backwards, then quickly climbed up and hid behind the tree. Almost at the same time, he aimed at the invisible man on the tree and shot him in the head.

The invisible man was eliminated, leaving only the last three challengers in the level.

But Tu Hua hadn't had time to be happy when suddenly someone shot a shot from behind him in the northeast direction, hitting his left chest.

Tu Hua glanced towards the southeast one second before he fell, and found that the gunman who had been hiding there had disappeared, which meant that the moment he aimed at the invisible man, the man had already moved behind him quickly.

It seems to have run into Gao Wan.

Tu Hua fell to the ground in pain, the bullets pierced his heart and head, he could be killed with one shot.Although the bullet had penetrated into his left chest, it was obviously deviated from his heart.

But he still lost a lot of blood, and his blood volume dropped sharply. With 400 blood volume, only the last 30 were left to survive.

Seeing this, Su Gechi quickly pulled him aside, and after the two of them hid, they frantically began to supplement his blood.

Although the shot just now knocked out Tuhua's 370 HP, but the last 30 will not decrease any more, so even if Su Gechi's healing is slow, as long as there is enough time, Tuhua can recover his vitality.

At the moment when the arrow was on the string, a system buzzer suddenly sounded in the empty sky.

【Ding--】

【Welcome to the fun cannibalism level. 】

The scene has not changed, it is still the scene of "Desert Island Royale", and Tu Hua's blood volume has not yet been replenished. He looked at Su Gechi strangely, thinking what kind of supplementary level is this?

But Su Gechi said in a low voice: "Virus program."

really!The cannibalism set by the virus program is not as simple as replacing the NPC with a challenger!

The other two gunmen didn't move either, as if they were quietly waiting for the system's verdict.Soon, the rules were promulgated:

[Rules: There are currently three gunners left in the level. Gunner A has a 100% hit rate, Gunner B has a 50% hit rate, and Gunner C has a 30% hit rate. The three gunners are asked to take turns to shoot, and each person can only shoot once Gun, live till the end wins. 】

Soon, each of the remaining three people had a flashing letter above their heads. The person who has been hiding in the due west direction is B. He has a 50% hit rate. The gunman who just shot at Tu Hua happened to be It's Gunner A, who has a 100% hit rate.

And Tu Hua is the unlucky shooter C, with only a 30% hit rate.

After the letters floated above their heads, the positions of the three people were clear at a glance, and the other two people obviously noticed this too, so they didn't continue to hide.

At this time, Tu Hua's blood volume has been covered by Su Gechi, and he has returned to the original appearance of the gunman. The three gunmen who look exactly the same look at each other.

Everyone has the possibility to shoot first, and since the system stipulates the hit rate, this proves that even if their marksmanship is accurate, people with a 30% hit rate will have a 7% chance of missing, and once they are hit, they will not hit the target. There is no problem of healing therapists, and they will be eliminated directly.

Tu Hua looked at the two gunmen A and B. Although he was very nervous, his brain was spinning rapidly.

His hit rate is only 30%, A's hit rate is 100%, and B's hit rate is 50%.If A chooses to shoot first, he will definitely kill B with a higher hit rate first, then his chance of death is only 30%; but if B shoots first, he will definitely kill A with the highest hit rate , but he is only half likely to kill A. Once A is not dead, A will kill him directly in the next round.

If he has only a 30% hit rate, should he choose to kill A first or kill B first?

Shooting in turn... one person at a time...

Tu Hua shuddered suddenly, and immediately raised his pistol and pointed it at the sky. With a bang, he was the first to shoot. He didn't aim at anyone, but fired empty.
