At the same time as approaching the chameleon, the chameleon did not give up the chance to survive, it seized the opportunity in an instant, and with the last strength of its strength it turned its stomach towards Zhang Xu, a black-green liquid attacked Zhang Xu as quickly as a crossbow arrow, and now he almost didn't react, his chest was sprayed by the chameleon's powerful corrosive saliva, and the golden dragon armor couldn't stop it, making a hissing sound.

Just this Zhang Xu also dodged most of the attacks, an old tree behind him was directly corroded, black burn marks remained on the tree, and it was still melting the old tree, and soon, the tree looked like it had been bitten off by a fierce beast.

Zhang Xu was shocked, fortunately he walked slowly, thinking that the dying chameleon had no attack power, but he didn't expect to be able to continue to launch such an attack, the chameleon stared at Zhang Xu with hundreds of big eyes, and the other eye was bleeding a mixture of black blood and the whites of the eyes, but the chameleon relied on smell and hearing to judge Zhang Xu's location, and if he was still close, then the chameleon would also attack with corrosive saliva.

What it wants to do is not to kill Zhang Xu, but to restore energy and repair its own wounds, it just wants to delay time!

Zhang Xu also saw it, did he just give up the attack and let it return to normal?

Zhang Xu didn't want to see such a good opportunity being lost, if only he had a gun, if there was no gun and a grenade to blow up this chameleon, it would also be revenge for Yu Hongda's little brothers, although Zhang Xu couldn't get used to them, but they were just humans......

Grenade...... Grenade...... Well? Gas canisters in the canteen? This method doesn't work, corroded gas canisters are not easy to explode, and it is easy to hurt themselves, so Zhang Xu is fighting against time, and his brain is running rapidly.

Potassium chlorate sugar can explode......

However, potassium chlorate requires too much dosage to be advisable, and there is a lot of sugar, and a small explosion cannot take the chameleon away in a wave......

Super corrosive ...... of concentrated sulfuric acid

Concentrated sulfuric acid is not advisable, after all, the chameleon's saliva is the same as sulfuric acid, will it be immune and harmless......

Manganese heptaoxide burns when it hits organic matter......

The school does not have a large amount of manganese heptaoxide, if time allows Zhang Xu to configure it by himself, it is still very simple, but the key is time......

Cesium metal with water will explode......

The cesium metal school is also only an experimental supply, and there is not much stock......

Liquid nitrogen and water are only a violent reaction, like smoke bombs......

But there was no real damage, let alone killing the chameleon......

That's right! forgot about this, so Zhang Xu didn't think about it, and immediately ran to Zhang Xu's school, looking for it from room to room......

"No, it's not ......"

"That's it, diethyl zinc!"

Although diethyl zinc is used in superconducting materials or other nano experiments, it also has other functions such as dopants and catalysts, for doping other samples or to accelerate the role of catalytic chemicals!

This diethyl zinc is very dangerous, after all, this is a high-level experimental product in the third year of high school, it can be burned when it encounters oxygen, and extinguishing the fire with water will only increase the burning, so only a special fire extinguisher can be used......

"These chameleons are dead!" Zhang Xu said confidently, knowledge changes fate, if Zhang Xu is a poor student without a grenade pistol, it is estimated that he can only give up this chameleon and let it harm the survivors, but it meets Zhang Xu, who is at the level of science and science!

In fact, many daily necessities can extract explosives, as long as the chemistry is good, the home is full of weapons, don't ask too detailed, come on and learn!

At this moment, Zhang Xu put an exclusive container of diethyl zinc more than half a meter high, which was stored in a vacuum, and contained about half a cubic meter of diethylzinc......

The extraction port is like the sprinkler head of a fire extinguisher, which can be used in combination with other vacuum or oxygen-free appliances, and now it can be like a flamethrower as long as it is sprayed against the air, and adding water can also greatly increase the fire......

Zhang Xu rushed to this moment and found that the chameleon had slowly moved towards the water's edge, the chameleon was already crawling slowly in the middle of the road, it saw that Zhang Xu had been absent for a long time, thinking that it was afraid of itself, and now it wanted to recuperate in its lair with peace of mind!

Zhang Xu would give it a chance to escape, picked up the car fragments on the ground, and quickly slashed through the chameleon's front paws like a flying knife, the sharpness of the car fragments greatly increased under high-speed movement, although it did not cut off one of the chameleon's front paws, but it was embedded with this piece of fragments on its front paws, and as long as it crawled, it was in severe pain!

"Shhh

The chameleon hissed in warning, it wanted to run away now, and if the human dared to stop it from going home, it would squirt its own saliva and melt the human!

Seeing that the chameleon did not continue to escape, since it did not run......

I'm not afraid that you won't leave, so take it now!

Zhang Xu held up the container of diethyl zinc and opened the nozzle, a flash of fire rushed to the sky, directly covering the chameleon's body, the chameleon also spit out a saliva, Zhang Xu used this jar to a gear, this container is to prevent corrosion and explosion, if the jar is broken, the leakage of diethyl zinc is estimated to be the entire laboratory and even a laboratory building will catch fire......

You can imagine how powerful this diethyl zinc burns is!

Diethyl zinc encountered the oxygen in the air like a fire burning the prairie momentum, quickly occupied the chameleon's whole body, the chameleon rolled, rolling in place, trying to remove the burning sensation on the back, but the chameleon's belly was facing the sky, just what I wanted, another fire scattered in all directions, and the flame stuck to the chameleon's abdomen, at this moment it was all charred black but the fire still did not have a tendency to dissipate, just like the leeches of the tarsal bones have been burning the chameleon, let you kill humans, this is to avenge our human beings!

The virus in the chameleon's body is looking for a solution to the flames, and the DAN stores the lizard's approach when it encounters a forest fire, and its body enters the water, so the chameleon ignores Zhang Xu and runs into the water quickly, like a lost dog......

However, the more water is used for this diethyl zinc, the more intense it becomes......

At the moment when the chameleon burrowed into the water, it may be the reason for too much water, Zhang Xu's previous experiments were to use a little water and diethyl zinc, and put it into the water at once, it is estimated that it is a violent reaction, and the water splashed, and a charred chameleon corpse floated in the water and burned violently......

Isn't it, I remember the use of concentrated sulfuric acid dilution experiments in junior high school, and you have to slowly stir along the glass rod to dilute it, if you pour it into the water at once, then you have the potential to be disfigured, young man...... The violent reaction will cause the water to explode and bloom, spraying sulfuric acid......

The chameleon still burns at a distance after death, and the flame on the corpse blooms a beautiful flower in the water like an unquenchable flame of death......
