Chapter O33 The Wonderful Use of Thermite

Before Fang Jinyan could return, he used a highly toxic chemical agent to kill a thug.

This made the other three thugs sweat profusely, but at the same time, it also deepened their vigilance against each other!

"You must not let that man come back!" Liu Haidong said categorically, "I'll continue to stay at the window, you guys will deal with that little first~, and then the three of us will work together to stop that person with all our might!" We have the advantage of numbers and terrain, no matter how strong that person is, he will definitely not be our opponent! ”

Originally, in addition to the window, there was another exit in the room, which was the security door near the corridor, but the security door was very strong, locked from the inside, and was blocked by several test tables of hundreds of kilograms, even dozens of zombies couldn't hit it, and it was impossible for people to open it, so they didn't have to worry too much.

He didn't think that Fang Jinyan's strength would be stronger than dozens of zombies!

"Understood, Brother Liu!"

Chen Yang and Yang didn't dare to slack off at all, although they originally saw that these two girls were not bad, and they were ready to deal with them after a good time, but Zhang Zhifei's death just now gave them a huge sense of crisis and fear, and naturally they couldn't take care of these anymore, they planned to kill these two girls first and solve their worries!

The two of them lifted the steel rod as thick as two fingers, and without saying a word, they rushed up to kill the two girls!

Originally, they thought that two girls, even with an axe in their hands, were not their opponents at all

But the result was a little surprising, the combat effectiveness of these two girls was not much worse than them

It can even be said that their combat skills are even above them, if it weren't for the big gap in strength and size, their combat effectiveness would still be above them!

This made Chen Yang and Yang extremely surprised: no matter what they said, they were all born of sports, and their combat effectiveness was considered the top level among the students, but they didn't expect that in the face of these two girls, they couldn't take any advantage for a while!

In fact, even Liu Yun and Xu Xiaoyao themselves didn't know that they already had such strong combat power at first, they were frightened by the other party's ferocious momentum, if the other party didn't want to kill them, they wouldn't dare to resist at all.

But after the fight, the strength of the current opponent is no more than this, and it is not much stronger than the zombies with heavy defects

In fact, it's not because the other party's strength is not strong, but because they are making progress so fast that they don't even realize it.

The reason for this is naturally because of Fang Jinyan's training of them, and more than once he took them out to fight with zombies, in such a battle of life and death, their potential was all stimulated, and their progress was naturally fast.

And the two thugs on the opposite side, although they have the best physique among ordinary people, they don't have the courage to fight zombies, and they don't have a master with strong combat experience like Fang Jinyan to guide them, so their combat effectiveness is still at the level of fighting with people in peacetime, all relying on their own brute strength

"Xu Xiaoyao, their strength is not good, we fought with them!"

Liu Yun instantly gained confidence and said to Xu Xiaoyao.

"Okay" Xu Xiaoyao replied, although she was still very nervous, she was no longer as overwhelmed as she used to be.

After fighting zombies, fighting the thugs is naturally much calmer psychologically.

When the two HKSI boys heard their words, they immediately felt very humiliated.

"I don't know if I'm alive or dead! Do you really think we can't beat you?! ”

The two of them instantly strengthened their offensive, picked up the steel rod, and slashed at the two girls frantically.

They are tall and have long arms, which makes them a big advantage in hand-to-hand combat!

However, Liu Yun and Xu Xiaoyao were not too flustered, but responded calmly, seeing the moves, dodging left and right, and did not fall behind for a while!

In fact, if it was hand-to-hand combat, they would have been subdued a long time ago, but the fire axes in their hands were very handy and very skilled, which made the two thugs very jealous

A powerful weapon that can also reduce the disadvantage of the body!

Seeing such a situation, Liu Haidong couldn't help but scold: "You two are bad goods!" I can't even handle two little ~~ sons! ”

"Brother Chen, don't blame us, the two of them are really evil! It's not easy to deal with at all."

Chen Yang hurriedly complained.

Yang added: "But Brother Chen, don't worry, they just give us a little time, and we can kill them immediately." ”

Liu Haidong actually saw it, he wanted to come forward to help, but he didn't dare to abandon the window, otherwise with that person's climbing degree, he might throw a rope and climb up in a few seconds - they had seen this person's strong climbing ability before!

However, he didn't worry too much, because he could see that Yang didn't brag, although the combat power of those two girls was unimaginably strong, but the physical disadvantage was still a little too great, and the endurance was even worse!

So after holding on for a while, Xu Xiaoyao was almost thrown off the fire axe in Yang Yi's hand, and her entire tiger mouth was torn! Blood gushing!

"Ahh

Xu Xiaoyao snorted, but she endured the severe pain and held the fire axe tightly, not letting it really be knocked away!

Because Fang Jinyan had warned her that if she lost her weapon in battle, she would almost die!

In this way, the two thugs regained their advantage and were bent on killing Liu Yun and Xu Xiaoyao, while Liu Yun and Xu Xiaoyao were struggling to support and fight!

On the other side, Liu Haidong hid in the shadows, staring at the grass where zombies roamed below

As soon as that person appeared, he would be fully prepared to fight, and he felt that even if he was the only one, he should be able to defend it, after all, the drain pipe had been destroyed by him, as long as he prevented the person from throwing the rope up!

Of course, you should also beware of the other party throwing thunder ~ tube up, but he is not a zombie without IQ, the other party puts thunder ~ tube

Throwing from the first floor to the third floor, this time was enough time for him to hide, so it wasn't really a big problem

On the contrary, he himself can throw something down and kill him!

What's more, Fang Jinyan must not dare to stay downstairs for too long, otherwise the zombies will definitely surround him soon

So he felt that he had done everything he could, as long as Fang Jinyan dared to come, he would definitely be able to stop him outside, or even kill him directly!

He was even a little looking forward to Fang Jinyan's arrival, waiting a little anxiously.

However, Fang Jinyan never appeared

"It doesn't make sense, according to their practice a few days ago, they come back at three o'clock in the afternoon every time, and now it's been a lot, why haven't they come back?!"

Liu Haidong felt a little bad, and felt that something was wrong, but after thinking about it, he couldn't find out what was wrong

He never expected that at this time, Fang Jinyan and Ye Suxue had actually quietly walked around to the door of the real room!

He underestimated Fang Jinyan's caution and carefulness, and every time Fang Jinyan took a step, he would observe any clues ahead, so before he reached the grass, he had already seen that something was wrong with the real yàn room on the third floor, the window panes were smashed, and the drainage pipe was also broken!

So he sensed the danger at the first time, and then grabbed Ye Suxue, not giving Liu Haidong a chance to see them come back at all!

Then he and Ye Suxue decisively threw away all the food on their bodies - these foods were collected by them at risk, they were very precious, but they had to throw them away at this moment, in the last days, sometimes they had to make such a choice, and they had to be decisive, otherwise if they hesitated, they might die because of it!

Fang Jinyan took Ye Suxue and went around in a big circle, unexpectedly through the corridor of the Guò Shi Yàn Building, and quietly sneaked back to the third floor.

Only a strong man like Fang Jinyan would dare to do this, there were zombies everywhere along the way, otherwise it would be impossible for him to do this if it weren't for his amazing combat power.

However, after arriving, there was an all-steel security door blocked in front of him and Ye Suxue!

An anti-theft door that dozens of zombies can't break through!

"It seems to be locked inside, and it's blocked, we should be able to hit it open," Ye Suxue said with a sad face.

She had already heard the fighting inside, so she was very worried.

"You don't have to bump at all."

Fang Jinyan replied, while taking out a paper bag about the size of a fist and a roll of wide tape from his arms, and then with an incomparably large number of sharp degrees, he pulled out a long strip of wide rubber and pasted it horizontally on the groove in the middle of the security door!

However, it is not completely attached, but only the sides and the bottom are attached, but the upper edge is not attached, so that a wide pocket is formed

Then Fang Jinyan opened the paper bag again, and evenly packed a red powdery substance inside this "wide pocket".

His hand was so fast and accurate, and this qiē movement was completely done in one go!

Immediately, he took out another silver-white metal strip, inserted one end into the tape pocket, fully contacted the red powder substance, and then used a lighter to heat the other section of the silver-white metal strip, and it was directly ignited!

Fang Jinyan hurriedly pulled Ye Suxue away and stepped back four or five meters away as fast as possible!

At this moment, a whole strip of powder held by the tape was instantly ignited, like fireworks, sparks flew everywhere, and an incomparably bright and dazzling light appeared!

Ye Suxue only understood at this time: this is thermite!

Thermite is a pink mixture of aluminum powder and ferric oxide powder in a certain ratio (1:2.95), when ignited with an ignition agent, the reaction is carried out violently, alumina and elemental iron are obtained and a large amount of heat is released, the temperature can reach 3oooc, far beyond the melting point of steel, so it can melt the generated iron!

And the silver-white metal strip in Fang Jinyan's hand before was naturally the ignition agent of thermite - magnesium strip!

It is mentioned in middle school chemistry that magnesium is a relatively active metal, which can be burned at room temperature and releases a large amount of heat, which can further fuel thermite!

Obviously, Fang Jinyan is planning to use thermite to directly fuse the entire security door from the upper middle!

Fang Jinyan waited for a moment, and suddenly ran on the spot, jumped high, kicked in the air, and kicked the upper part of the security door fiercely!

The all-steel security door was broken in two from the middle under his kick!

The lower part is still locked, but the upper part has been kicked open by him!

Of course, this is not because Fang Jinyan's power is infinite, but because the thermite has almost blown the security door, and he kicked it so vigorously that he just separated it completely before it cooled down and solidified again!

As for why you want to kick it, it's because it has neither a door lock nor a real table, and it doesn't take much force to kick it open!

If he kicked it below, then even if Fang Jinyan's strength was four or five times greater, it would be impossible to kick it away!

Fang Jinyan's violent kick was like a bolt from the blue to everyone inside!

Even the four people who were originally fighting stopped and were stunned to see the security door suddenly kicked in half!

Then they saw Fang Jinyan easily jump in from it, like a divine soldier descending from heaven!

Everyone was stunned, this is too exaggerated, isn't it?!

He can even kick the security door with one kick?! Is this still human?!
