Chu Chen has been processing gunpowder.

The materials here are very complete, saltpeter and sulfur can be dug directly, and the only thing that takes a little effort is charcoal. In the past few days, he has gotten everything he can burn to burn.

The obtained charcoal is ground into powder with saltpeter and sulfur, mixed according to the proportion, and it becomes the most traditional black powder.

Yu Hanyan is very quiet these days, basically Chu Chen said what she did, never said much, and never asked more. Everything started from that time when Chu Chen teased her, and she returned to that cold appearance, which made people feel cold.

"It's finally good, I'm exhausted." Finally, Chu Chen finished using the last materials and stood up.

"Is that enough?" Looking at the large pile of black powder, Yu Hanyan asked the first question in the past few days.

Chu Chen scratched his head and said with some uncertainty: "It should be about the same, these black powders are thirty or fifty thousand catties, and if they are all detonated, they are equivalent to hundreds of missiles, and it should be no problem to blow up this mountain." ”

Although he is not a full-time explosive, Chu Chen still remembers the basic power of gunpowder very clearly.

"Missiles? What is that? Yu Hanyan was suspicious in his heart, but he didn't ask much, just said, "What now?" Direct ignition? ”

Chu Chen fell down in an instant, and just hurriedly pulled her aside, "It's not stupid, do you think your body is harder than this mountain?" You won't die if the mountains blow up? ”

"Oh! I don't order it. ”

Listening to Yu Hanyan's unconscious words, Chu Chen was instantly speechless.

In the next time, Chu Chen was busy in the mountain with Yu Hanyan like a pangolin.

Everything went on quietly, and they carved a circular passage in the belly of the mountain, surrounding the belly of the mountain where the pool of blood was. After careful calculations, the two found a place to bury the gunpowder and arrange the leads.

Chu Chen's plan was a series of explosions, the first ignition, eighteen points in the annular passage would explode at the same time, and the gunpowder buried at each point was a thousand catties.

This round of explosions will inevitably collapse the mountain, and all the passages in the cave will be blocked, so that even if the people and monsters inside are not dead, they will become turtles in the urn, but they will not be able to escape.

After the first round of explosions, the lead will continue to burn in the center of the mountain, and at the end of the burning, there will be no less than 30,000 catties of gunpowder buried there. This is the real killing move that destroys the world, once it explodes, the people and monsters inside will definitely not be spared.

"I hope it happens!" Everything was ready, Chu Chen smiled tiredly.

This project is huge, but he is mainly the one who contributes, he is not at ease to let Yu Hanyan do these things, in case he accidentally makes a spark or something, wouldn't he die before he can get out of the school?

"It will be done, definitely!" Yu Hanyan finally didn't hit Chu Chen again, but clenched his fists and encouraged. As he spoke, he took out a white silk handkerchief from his waist and handed it to Chu Chen.

Chu Chen smiled as a result, sniffed it, and put the silk handkerchief into the storage bag in his intoxication, and in Yu Hanyan's angry eyes, he directly wiped his sleeve on his face.

"Scoundrel, give it back to me!" Yu Hanyan said coldly.

"What to give you back?" Chu Chen blinked and said cutely: "Be good, don't make trouble." Go and prepare and prepare, and soon the fire will be lit. ”

Yu Han's smoke snorted, and Chu Chen carried a bag of explosives and climbed through the gap to the top. Carefully dug down a square stone, without alarming anyone.

"Hopefully it will bring them all back!" Taking a deep breath, Chu Chen ignited the explosive bag and threw it directly through the hole dug out, and if nothing else, this heavy explosive bag would eventually fall into the pool of blood.

Without waiting to see the results, Chu Chen hurriedly blocked the hole with a square stone, and then looked down through the tiny gap.

Sure enough, the explosives bag sank into the pool of blood smoothly, and before the guards could understand what was happening, there was a sudden "boom", and the ground shook.

Hundreds of catties of explosives directly exploded the blood pool, and the blood rain was sprinkled all over the sky, and Chu Chen could smell the smell of burnt and gunpowder smoke from afar.

The sudden appearance of the situation caused chaos below, and various sirens continued to sound.

People kept coming from all over the place, all carrying swords and swords, and their faces were full of vigilance. Not long after, Yu Wei's figure also appeared in the crowd, but unfortunately, in the end, Chu Chen didn't see the masked man.

"How's it going?" At this time, Yu Hanyan also came over, saying that he was preparing, but in fact, there was nothing to prepare at all.

"It looks good, I guess it won't be long before anyone who can feel it in Black Wind Ridge arrives. I don't know if the masked man is in Blackwind Ridge now! Chu Chen replied.

Yu Hanyan didn't say a word, just pulled Chu Chen away, and looked down through the gap with a pair of wonderful eyes. After a while, he turned his head and said, "Prepare to light the fire, that masked man is no longer in Black Wind Ridge at the moment, there should be something going back to the Royal Beast Gate." ”

After speaking, he ignored Chu Chen's reaction and walked away alone.

"Spirit! Isn't it just that you can read lips? What's so great that I can still make gunpowder! Staring at Yu Hanyan's unconscious writhing hips, Chu Chen was guilty in his heart.

The first round of detonation had long fuses and elaborate ignition devices to buy enough time for a safe evacuation.

Somewhere in the belly of the mountain, Chu Chen lit a stick, inserted it directly into the center of the ignition device, and then evacuated with Yuhan's cigarette butt without looking back.

"What if I don't ignite?" During the evacuation, Yuhan flue.

"Then come back again." Chu Chen shrugged his shoulders and said with a smile: "Don't worry, that situation shouldn't happen." It takes at least two pillars of incense to burn the stick, and when it burns underneath, it will burn the rope holding it in place, and then it will fall and ignite the gunpowder underneath. At that time, the flames will rapidly extend in eighteen directions at the same time until the first round of detonation ......"

"What if the stick breaks in the middle and falls directly to ignite the gunpowder below?" Yu Hanyan said again.

"I knew you would ask this, but I had already thought about it, and that is...... Hurry up and run! ”

Chu Chen's voice suddenly became high-pitched, he is not a god, not everything can be solved, in case the gunpowder ignites in advance...... Well, hopefully it doesn't come to pass.

Quickly came all the way to the waterside of the cave, and without saying a word, Chu Chen directly grabbed Yu Hanyan's hand and jumped into the water that smelled of blood.

Following the undercurrent under the water, the two swam out against time. In the darkness, the two suddenly felt that the mountains were shaking, as if the sky was about to fall.

"Crow's mouth, sure enough, it exploded in advance!" Chu Chen couldn't wait to slap Yu Hanyan's ass twice, who told her not to read the good and miss the bad?

The danger was approaching, and Chu Chen had to try his best to increase the speed of swimming. In the darkness, the feeling of the mountain shaking is getting stronger and stronger, as if it will collapse at any time.

It was extremely difficult to swim along the way, and many times there were cracks in the rocks that had just swam through, and large stones fell to block the waterway.

It's a race against death, and they must get out before the mountain collapses completely, before the second big explosion hits.

Just as Chu Chen saw a light not far ahead, suddenly a huge mountain fell down, blocking the waterway, and his vision was dark again.

"Damn it!"

Chu Chen's heart tightened, if he didn't get out as soon as possible, the situation would become more and more dangerous. He didn't think that he was a monkey who could be crushed under the mountain for 500 years without dying.

Yu Hanyan also felt chills in his heart, he didn't expect to prepare so much, but in the end he couldn't evacuate safely.

"Are you really going to die here?"

A frightened thought came to her mind, and Yu Hanyan was surprised to find that she didn't seem to be too afraid, as if there was a reassuring power constantly injecting into her heart.

She subconsciously clenched Chu Chen's palm, and secretly looked in the direction he was in the dark. Admittedly, she couldn't see anything, but she knew exactly where he was, and he wouldn't leave her alone.

It's a strange feeling, but it's real. She even weirdly thought that it might be nice to die here, at least not alone in the ice and snow.

In the midst of this scattered thought, Yu Hanyan suddenly found that the surroundings lit up. She saw that Chu Chen had already drawn out his long sword, and the blue flames burning on the sword could not even be extinguished by water.

"It's amazing!"

Yu Hanyan sighed in his heart, but Chu Chen was already roaring in his heart. The star source of Xingfu flickered rapidly, and the rich star power was like an endless stream of surging river water, rushing and flowing in the meridians.

A powerful aura emanated from his body, and a purple cloud quietly appeared above his head, and the giant beast in the cloud quietly probed its claws.

"Biluo Burning Flame!"

With a roar in his heart, Chu Chen suddenly took out his sword. The first sword of the Xuan-level top-grade Zhu Heavenly Hell Flame Sword, Biluo Burning Flame, with the blessing of the fifth-grade flame origin, showed the edge of destroying the heavens and the earth.

The sword fell from the blue, and the flame came out of the yellow spring.

It should be an incomparably hot flame, but at this moment, there is a strange coldness, which is immortal in this underground tunnel.

With an indomitable momentum, the flame sword blasted directly towards the boulder that blocked the way.

The moment it hit, a huge force exploded, and the rubble exploded, and in an instant, even the cold water around it boiled.

Chu Chen stiffened against the jet of water and didn't close his eyes, because of his persistence, he successfully captured the first ray of light after the boulder was penetrated.

"Let's go!"

With a burst of applause in his heart, he shook his hand violently, and with huge force, he directly threw the jade cold smoke towards the light. Like an arrow from the string, Yu Hanyan quickly left the dark passage and entered the main trunk of the river.

Everything just happened in an instant, Yu Hanyan didn't have time to react at all, and his body was already moving forward rapidly. In her panic, she glanced back, and it was a face of great determination, with an uninhibited smile on it.

It's just that the smile is gradually moving away and fading. Because of her advance, because he is retreating, and because of the collapse of the mountain, the waterway has been completely sealed.

"Why ......"

Yu Hanyan's heart was very blocked, as if there were a thousand words, and in the end it was only condensed into three words.

Why? Why is that? She was asking herself, asking Chu Chen, more like a helpless interrogation of the sky.

At this moment, there was another earth-shattering loud noise, the mountain collapsed, and a huge mushroom cloud soared into the sky, covering the sky and the sun.

The second big bang finally sounded!

The violent shock wave swept through, and Yu Hanyan was sullen for a while, and the reverse blood spurted out, and he almost fainted. Looking at the falling rocks, she finally knew that it hurt.

When you feel distressed, you will cry.

The first tears of her life quietly melted into the water, she couldn't see it, and he couldn't see it.
