Acid, an extremely domineering mass of biological acid was launched from Mei Jun's body and splashed on the old banyan tree.

In an instant, a fierce chemical reaction occurred on the trunk of the tree, and the hot white smoke rose from the "zilazila", and the wisps floated into the clouds.

In less than a moment, a layer of charred charcoal was revealed, and the bio-acid continued to penetrate into it, emitting a scorching heat in a violent reaction.

This reaction continues, perhaps only when the biological acid is depleted.

This terrible high concentration of acid is much more domineering than the mixed acid in the acid sea, it is made by Mei Jun integrating all the devoured mushroom genes, and then compressed by his hands at a certain concentration, which greatly increases the corrosiveness and oxidation.

If a living person touches it, he will definitely be able to expose his white bones and rot into charcoal, which is simply terrifying!

"Boom!" the trunk finally broke after being corroded by biological acid, and the old banyan tree crushed it by its own weight, and it was about to fall to the high wall.

"Bang!" the metal wall seemed to have been hit by a heavy hammer, and with a muffled grunt, it caved into an oversized crater, and the wall burst into metal cracks, but it still stood.

Mei Jun looked at this effect and said happily: "Enough." ”

He didn't have much hope for this method, just a few cracks in the metal wall.

Immediately, his body secretes acid out of the body and stores it inside, using compressed biological acid to increase the concentration.

"Poof!" a cloud of viscous bio-acid landed on the high wall, but he didn't spray it on the crack in the metal.

"Shhhh

Sure enough, the concentration of biological acids was too high. He sighed inwardly.

It is because the oxidation is greatly increased, and in the process of corrosion, the metal also generates a dense oxide film, resulting in passivation.

The mixture of mushrooms that used to corrode these four walls was not partly the reason.

Mei Jun saw a mixed acid that had no effect, but it was also expected by him.

Because "passivation" is a common knowledge point in high school chemistry.

Although he has been out of school for more than ten years, he is still familiar with this common-sense knowledge of chemistry.

Just like the chemical reaction between concentrated sulfuric acid and iron, because the oxidation of concentrated sulfuric acid is too strong, it will directly form a dense oxide film on the surface of iron, so that iron passivation can not continue to react.

"It looks like we need to adjust the concentration of the acid. ”

Mei Jun had just tried to test whether the high concentration of acid she had produced could erode the metal wall.

He was once again tinkering with his body, producing or recovering the bioacids whenever he wanted to.

Immediately, he flew to the crack in the wall, and his body squirted the freshly mixed acid, which flew into the crack in the metal.

As soon as the "zilazila" was splashed up, the metal without the oxide film instantly reacted violently, bursting out of dazzling white smoke.

Soon, the metal wall was corroded by biological acid and made a small hole.

He knocked down the banyan tree to see how strong the metal wall was, but the wall was not strong enough, and it was squeezed by gravity, and immediately burst into several cracks.

"What a clever slime mold... Then the capture begins. ”

The woman was on the screen Mei Jun was amazed at the IQ of "this slime mold", but when she saw that he wanted to escape from prison, she immediately sent a command on the console.

More than a dozen blackened drones flew out of a room in the villa, all made of steel, flapping propellers made of metal and flying into the courtyard in a neat array.

These dozen drones are loaded with smart chips, which can analyze the distance and adjust the position in the array on their own.

"Whew~ I'm tired, let's call those two little brothers first. ”

Mei Jun breathed a sigh of relief, and he didn't forget the two little brothers when he was about to escape from prison.

It had just taken him a lot of energy to make a small hole of about 5 centimeters in the solid metal wall.

"Ah, human society, Lao Tzu is coming back..."

Mei Jun flapped his wings behind him, and flew to the scorched earth of the yard with the excitement he couldn't wait.

The two younger brothers were also waiting for him.

"Big brother, we can get out of this ghost place!" Su Powan said very excitedly, and the two small compound eyes on the cone were about to cry.

If he hadn't had tear ducts, he would have burst into tears now.

Since that awakening, he has been here for many days, and every day he is either chased by bugs or beaten by bugs, and the real feeling makes him understand that this is not a dream at all... It's all bitterness!

"Ahh

Stag Armor Aji was originally a native of this place, but it was not sad, and there was a faint excitement.

It used to be basically invincible in this place, and it felt lonely when it stood at the top all the time, and it was very much wanted to go out and see the outside world, and Mei Jun also said that there was a chance to make it a legendary terrifying Homo erectus.

"Let's go!"

Mei Jun almost cried, counting from the day he was reborn, he hadn't touched his mobile phone and computer for many days.

"I just want to be a person~"

He suddenly raised his head to the sky and roared, shouting out the unhappiness of being reborn.

But in the eyes of a woman, this becomes a signal of some kind of prison escape.

"Let the old lady's dozen special treasures kill you all!"

She pushed her black-rimmed glasses with her index finger, and immediately pressed a red button on the remote control, and the propeller on the head of the drone suddenly accelerated.

The steel propeller cut through the surrounding air currents, stirring the sound of the howling wind.

More than a dozen execute this command at the same time, because this remote control can control this drone platooning at the same time.

Then, the power grid in the yard suddenly stopped, and they were put in the future menacingly.

"Big brother, it seems... Something is not good!"

Su Pofu was tied to Aji's back by Mei Jun's mycelial hand, and his two small compound eyes stared at the dozen or so drones that were desperately chasing them.

"Got it, don't talk nonsense. Mei Jun changed his voice again and knocked on the back of the spade armor, "Aji, speed up, hurry up!"

"Yes, Lord Fungus. "The stag armor flew faster again.

There was no way, Su Pofu couldn't fly long distances, but he couldn't leave him alone.

Immediately, Mei Jun clasped the spade armor with more than a dozen mycelial hands, and several hollow round pipes were simulated behind him.

"Air compression, jetting!"

He sucked air into his body, but did not compress it into a liquid state, just a counter-force propulsion by firing an air cannon.

Aggie's speed picked up again, and he was about to fly to the entrance of the cave.

"Hmph, there's no way I'm going to get you out of prison. ”

The woman snorted coldly and pressed the red button on the remote control.

The dozen or so drones that received the command were faster, and became a dozen blurred black shadows.

"Shoot sticky glue. ”

The woman controls the direction and presses another functional button.

"Puff~Puff" As they were about to approach Mei Jun behind them, the first of the three round tubes at the front of the drone emitted a cloud of white mucus glue.

And a dozen UAVs, that's a dozen regiments.
