"When oxygen is burned, carbon dioxide forms in the air, and if it is not burned completely, carbon monoxide is formed. The smoke contains carbon monoxide, so it can poison people, and although my flame burned the smoke, completely turning carbon monoxide into carbon dioxide, it also incinerated most of the oxygen in the air, which caused them to be hypoxic and comatose. ”

Ye Mu had a lot of them, and several of them were still confused. Ye Mu was not surprised, because even the most technologically advanced pharmacist empire had not yet involved chemistry class. Perhaps the current chemical principles are only in the hands of a small number of arms dealers

"So what do we do now?"

Several people questioned him.

Although they don't understand it very well, they can hear it a little - oxygen is very important, and without oxygen, a few people will die of carbon dioxide poisoning just like the group of people on the ground.

"Marentha, you can control the five elements, right?"

"Theoretically, yes. I can use gold, wood, water, fire, and earth with ease. ”

"Very well, you come here......"

Ye Mu and Marensha spoke to each other, and after finishing, Marensa looked at him suspiciously, "Can this work?"

"Well, trust me. ”

Ye Mu nodded.

"Okay. Marensa agreed, and with a gesture of her hand, a part of the ocean rose up, crashing into the wall under her control. At this moment, Ye Mu saw that there was also an invisible barrier under the sea, and several people were locked in a glass ball by one person.

The sea water hits the wall, but no matter how much it hits, it can't be broken.

Stone transformed into a three-headed demon dragon and slammed his three long heads into the barrier, but instead of breaking it, he broke his head and bleed.

"Master, there's no point in doing this. ”

"But you have to do it, sit back and wait, there is no point in it except death. ”

"Yes. ”

After Xiong Bingwei nodded, he rushed to the invisible barrier with his trident, and under the attack of several people, he did not receive any results.

The oxygen gradually became insufficient, and it became difficult to breathe, and finally everyone, even Stone, slowly landed on a boat, gasping for air, but unable to breathe any oxygen.

Suddenly, a few skirts were on the lin, and it seemed that he had fainted.

Time passed minute by minute, and after about five minutes, several people were completely unconscious.

At that moment, a man hiding in the shadows burst out with an inaudible laugh, "Uh-giggle, hand-to-hand, hand-to-hand!"

The man carried a large bottle on his back and had two tubes held in place with rope in his nose, which were connected to the bottles. He smiled ugly, walked into the barrier with a large bottle on his back, and he didn't seem to be able to fly, and took a boat and came to Jirao's side.

"Tut-tut, these are all money, money!"

He pulled out a stack of wanted warrants with several sketches of Rao drawn on them.

"Grev Luffy, a bunch of pirates...... There are also a few people who are working against the Order, as well as this traitor. This time, I made a big deal and made a lot of money, hahaha!"

The man smiled up, but was stunned to see a ball of water suspended in the air, surrounded by a cloud of thunder.

"What's that? a pearl celebrating my victory? ahahaha-"

The man laughed loudly, and the balloon of water fell and landed in a large expanse of water.

Then he heard a thunderclap, and then the man heard a crackling sound, he raised his eyes to look, and saw countless fish and shrimp jumping out of the water, or directly rolling their eyes, and dying on the surface of the sea.

"What is this?"

There was an inexplicable sound of "hiss......", and a steady stream of white mist flew out of the sea. Just when he didn't know why, Ye Mu suddenly moved.

"How could he wake up!"

The man was startled, jumped on the boat and turned around to run, but Ye Mu had already woken up.

"You're behind it. ”

Ye Muba, the whole person disappeared in an instant, and the next moment he came to the man, grabbed his neck, and lifted him into the air

"You're lying to me! You're cheating, cheating!"

The man shouted loudly and struggled twice, but he was punched directly in the face by Ye Mu, and he was beaten to the ground, and his eyes were full of stars.

"Don't give me too much to talk about. ”

Ye Mu shook the blood on his fist, turned his neck, and suddenly the sound of crackling bones colliding came out.

"I'll admit, you're a vicious move. If I hadn't happened to know a little bit about chemistry, I would have died at your hands. ”

"Chemistry, what chemistry?" the man asked again.

"Electrolysis of water produces oxygen. Ye Mu smiled contemptuously, "You know that carbon dioxide is used to kill people, but you don't know that oxygen is produced like this...... Should I be smart or stupid?"

"You ......"

After the man's words were finished, Ye Mu gave him another hard punch.

Slowly, several people and pirates woke up, and when they raised their eyes to look into the sky, they saw Ye Mu beating a strange man.

After a while, Ye Mu knocked the man unconscious and threw him on Gref Luffy's boat. Flicking his wrist, he looked at a few people and said, "Everything is going well, the enemy has been dealt with." ”

"I can't believe that you can get rid of him, Captain...... I really have so much admiration for you. Louis looked at Ye Mu with admiration.

"Don't worship me, you should worship science. ”

Ye Mu stretched his waist and said, "Xiong Bingwei, tie him up and hand him over to Greif Luffy to dispose of." ”

"Okay. Xiongbei agreed, and went to tie up the man.

After Glevy Luffy woke up, he looked at the enemy who burned his ship, and he was anxious to clean up his subordinates, viciously cleaned him up, and then killed him and threw him into the sea to feed the sharks.

After a period of drifting, we finally came to the edge of the north coast.

On the eve of landing, the target of Glive Luffy and his party was too big, and in order to reduce the difficulty of being found and talking, several people and Glive Luffy took the action of going ashore separately.

Ye Mu and his party went ashore first, and Gref and his party went ashore on a later day. When they left the ship, they left behind the food, water and other necessary survival materials in their hands, and then went ashore.

The north coast is different from the south coast in that it is still a fishing village in a port city. The villagers live in yurts and other buildings, and they are a group of tiger people, all of whom do not look strong, but they are all lean and lean, with little muscle.

"Welcome to Mr. North Coast Village. ”

The tigers found out that a few rao were coming, and a half-old man who looked slightly older and had a higher status came forward to talk to a few people.

Ye Mu stepped forward and arched his hand and said, "Hello, this tiger brother." ”

The tiger man squinted his eyes, looked at the group, and finally stopped his gaze on Ye Mu. He was a little surprised and puzzled, and asked, "Where is your orc Peugeot?"

The so-called orc Peugeot, just like Louis's rabbit ears, the bear ears and bear nose of the bear guard, and the elf ears of Marentha, belong to a kind of symbolic thing that can distinguish the difference between orcs and humans at a glance.

Remember that I have a permanent address for a bronze tripod
