Yexi: "Yes, in fact, fire and water are compatible under certain conditions, fire can lift water, and water can also help fire. ”

Xiao Baobao heard for the first time: "Oh? How so? ”

Yexi: "Well, senior brother come with me." ”

The two returned to Lingzhou, called Kongkong and Jin Feng, and thought about it and called the red line real person as well.

Yexi sat at the table, holding a pen in one hand, and the table was covered with white paper.

"Just remember what I said, don't ask me why."

The red line real person looked at her rare serious appearance, and couldn't help but wonder: "Shouldn't you have done something again?" Can't hold it anymore? ”

Night Creek: "... Master, you just listen. ”

The four sat up straight.

Yexi began to say: "Fire, burning, needs three conditions, one is combustible, the second is combustible, and the third is combustible. ”

Write three lines on the paper and draw a horizontal line after the three conditions: "Combustibles, such as wood, strips of cloth, oil, etc., etc., etc." The flammable point is that the temperature reaches a certain level, for example, if it is too hot in summer, the oil tree will burn on its own, right? ”

The oil tree is a very light and loose tree, which secretes an unpleasant smell of oil all year round, and when the air temperature is high, this kind of tree will spontaneously combust.

The four nodded, understanding.

Yexi drew a circle on the combustible in the middle: "The combustible is oxygen." "Write down the chemical formula of oxygen.

The four of them began to be circled, which was... Runes?

Yexi took a low-level fire talisman and threw it on the ground, the flames jumped, and then took a small transparent cover to cover the flames, and the flames shook and slowly extinguished.

Xiao Baobao's eyes lit up: "It's extinguished so soon?" This fire talisman will burn for at least a quarter of an hour. ”

Yexi nodded: "Because the hood isolates the air outside, and the oxygen that can support combustion in the air inside is exhausted, the flame will naturally be extinguished." ”

Everyone was still confused.

Yexi: "Just remember, the air we breathe is actually the oxygen in it that sustains our lives. The air is not all oxygen, and oxygen, in addition to sustaining life, also allows fire to burn. Without oxygen, the fire cannot burn. Don't ask me why, rote memorization. ”

The four of them nodded dumbly, is this the family inheritance of Yexi?

Yexi nodded with satisfaction: "Now, let's talk about water." "Write the chemical formula of water on the other side of the blank paper.

"Do you see anything?"

Empty raised his hand: "This half is that and that... Oxygen, well, doesn't seem to be quite the same either. "There's a little symbol missing.

Nightstream: "Very smart. Water, hydrogen dioxygen, can be separated. "I drew a vertical line in the middle of the chemical formula, and a vertical line at the bottom to write the chemical formulas of hydrogen and oxygen.

Xiao Baobao's eyes lit up: "Water can separate oxygen, can... Combustion? ”

This is also a top student.

Yexi nodded: "Oxygen can help combustion, while hydrogen can burn, that is, under certain conditions, water can burn, and the power is huge." ”

Jin Feng was studious and asked: "What conditions?" ”

Night Creek: "The simplest, high temperatures, thunder and lightning." Senior brother, you put a high temperature fire. ”

Xiao Baobao raised one hand flat, and a beam of fire rose in his palm, turning from orange to red and blue.

Yexi used her spiritual power to take a layer of water from the teacup next to her, and pressed it thinly and thinly wrapped in Xiao Baobao's flames.

With a stabbing sound, a burst of mist rose, and the flames suddenly became larger and more intense, and slowly returned to normal.

Startled Xiao Baobao.

Yexi smiled, that is, the monk, dared to do this experiment.

"Senior brother's palm flame outer layer is high enough to separate the water vapor and turn it into hydrogen and oxygen, so the fire is big."

Looking at the expressions of the four people, he simply said, "Just remember it." ”

Four: "Oh~"

Jin Feng asked again: "The thunder and lightning that my sister just said..."

"Thunder and lightning can also separate water. In fact, thunder and lightning are high-altitude water vapor masses, that is, clouds, which are produced by extremely fast friction. ”

Four: "Gah? "Isn't it the mutated spirit root of the golden spirit root?

Yexi shrugged: "I don't know how the spirit root mutates, but that's what I learned at home." ”

The red line real person muttered: "Water, it can be burned, and it can also produce thunder and lightning, how do you feel that the water spirit root is the most powerful spirit root?" ”

Yexi: "I don't know if the water spirit root is powerful or not." But water is the source of life, and without water there is no life. ”

Therefore, in the last days, all the water resources are polluted, and the daily life of human beings is so miserable that they can't drink water.

Xiao Baobao pondered for a long time: "Can you use your sword?" ”

"Do experiments, you can." Yexi took out the Chidian Sword and threw it to Xiao Baobao: "Find a place where no one is and try again." ”

He actually popularized science for the monks. I don't know if Tiandao will go crazy if he knows it.

Swallowing the sky: "I have gained knowledge." ”

Huobao's eyes kept rolling, and he didn't know what he was thinking.

Puzzled: "What did you learn in that world?" ”

Night Creek is deep: "Many, many, many, from protons to universes." ”

No return: "... It's all fur, right? "It sounds amazing, but why haven't you even comprehended the law?

Yexi: "..."This king just didn't enter the Academy of Sciences.

The four people who were stuffed with a head of new knowledge went back in a daze, looking like they wanted to comprehend, but it was estimated that it was difficult.

The ten major sects were about to disperse, and they said goodbye one after another, and many buildings and ships flew into the sky and flew in different directions.

This time, Yexi did not use his own spirit boat and lived on the building boat. After walking for a long time, I said hello to Xiao Baobao, and quietly got off the stairs and returned to the secret realm of Ruodu.

The square laid out by the Hidden Family was still there, and Yexi stood on top of a pillar, hiding her figure. She just blends in with her surroundings, does not emit spiritual power, and has no life characteristics, unless someone happens to bump into her, it is impossible to be discovered.

This wait was ten days and half a month, and when Yexi felt that he was about to turn into a stone, he saw a dark shadow coming over in the sky.

"Oh my God, I thought I was doing something wrong."

There was a building boat, there was no mark, the people on it were very cautious, the people didn't come down, several divine senses swept down first, and they patrolled countless times, and the place where the night stream was located was also swept, but the divine consciousness did not find her. After checking the cracks in the stones on the branches, someone came down.

Tianxuanzong, Xiaoyao Sect, hidden family. Among them, the hidden family standing close to Shui Zhenzhen and Zhuo Yan.

Yexi hooked the corners of his mouth, sure enough, they got it, thief God.

It is estimated that the negotiation has been discussed on the road, and when they arrived at the square, Shui Zhenzhen and Zhuo Yan stood up, and the two of them played a set of mysterious tricks together, and slowly opened a hole in mid-air, and there was a rich aura at the entrance of the cave.

Yexi went to see the hidden family, although all of them looked indifferent, but there were still some resentment and dissatisfaction in the eyes of a few people... Eat one's heart out.

Yexi's heart moved, and the group chatted: "You said, that dove magpie moving the sky array, is it known to all the hidden families?" ”

Those few people were a little too jealous, if they knew that they still had a chance to get the Ruodu Secret Realm, they could always take some.

Can't get closer, the three little ones can only stare wide-eyed.

After reading it, Swallow Tian said: "Those stinky faces are not from Yuhe's family, and the marks on their clothes are different from Yuhe's brothers and sisters." ”

Yexi smiled: "It seems that the Dove Magpie Shifting Heaven Array is just the hands and feet of the Yuhe family. The hermit family is not monolithic. Hee-hee, that's great news. ”

Swallowing the sky: "Wait a long time before spreading the news, and don't give Yuhejia a chance to explain." ”

Yexi nodded, watching the people below begin to enter the secret realm, Tianxuan Sect and Xiaoyao Sect also had people enter, and the two sect masters followed up, but the combined number of people was comparable to the number of people in the Hidden Family.
