Isu stared, "You're Xue Ling?"

"I'm sorry, teacher, I'm late. ”

"I was late for the first day of class, ...... you" Yi Su suddenly remembered something, looked at Xue Ling a few times, and said softly: "You find a seat to sit!"

"Yes. Xue Ling hurriedly looked left and right, and walked quickly to the middle row.

"Trouble let's go. ”

The cold voice woke up Mo Lun, and he came back to his senses from the information fed back by the chip, and found a young girl standing beside him, with a pair of clear and beautiful eyes, as if a clear spring flowed, flowing past Mo Lun, and landed on the seat next to him without stopping.

In the middle row, where Moren sits, is a long table and bench that can accommodate three people to study, and he is the only one sitting at the whole table. The girl came over, apparently intending to sit here.

Moren got up and let the other in.

In fact, he could let the girl go through from the other side, but he had to pass the podium, and the girl who was already late was reluctant to go. Mo Lun didn't care, just got up, what could this be? He quickly invested in the information fed back by the chip, and his heart was a little excited.

After its first unexpected success, the Elixir failed again, because he didn't have many materials to bring, so he didn't dare to waste them. Recently, I have been letting the chip analyze the reasons for failure and success, constantly summarizing and analyzing various factors, and just now, I finally got a complete set of refining methods.

According to the chip's prompt, as long as Mo Lun does not make mistakes, then the success rate of the 'Rebirth Elixir' is close to forty percent. That's already a high success rate. Although the 'Cleansing Elixir' has been formulated many times, the success rate has only increased to 42% so far.

Compared with the Qingling Elixir, the rebirth elixir is undoubtedly more difficult, but the chip combined with the refining data of the "Tuojing Elixir" and the knowledge of the medicine collected in the academic area in recent days has solved several difficulties in refining the "Rebirth Elixir", and the success rate has increased instantly.

Having experienced the effects of the "Elixir of Rebirth", Mo Lun was already a little impatient. If it weren't for the fact that classroom knowledge was equally important, he would definitely go back to the tavern to refine potions.

Xue Ling looked at the podium with a serious face, as if she was waiting for Teacher Isu to give a lecture. Teacher Isu wanted to speak and stopped, his lips opened lightly a few times, and he was stunned and didn't speak.

It's a huge classroom, and it's a little weird quiet.

Mo Lun couldn't help it, and kicked the girl with a serious face next to her, the girl looked at her coldly, and her good-looking eyes flashed with a hint of anger.

Looking at the girl, who was about fifteen or sixteen years old, Mo Lun had to give up his silence and said loudly: "Should you go to the podium to get your textbook?"

Xue Ling was stunned, her eyes widened, and she looked up at the podium. Sure enough, the teacher was looking at her, his mouth slightly open, as if he was about to call her up.

Hula, the girl stood up and walked quickly to the guide of Yisu, "Teacher, I want to get the textbook." ”

Isu recalled the girl's personality introduction, smiled bitterly, picked up the last set of unfinished textbooks, and said warmly, "Go! ”

After Xue Ling came back, her delicate body writhed unnaturally for a while, glanced at Mo Lun with her peripheral vision, and whispered, "Thank you!" The sound was smaller than that of a mosquito, but Mo Lun heard it, looked at her, and brushed it, and the girl's neck turned red.

"The contrast is too great. Mo Lun was a little speechless, shook his head secretly and continued to flip through the textbook.

Fortunately, at this time, Mr. Isu, who was on the podium, finally gave a lecture.

"Now that you can enter the elite class, you should understand the basic ninjutsu knowledge. In order to improve the learning progress, let's go straight to the main lesson! Please turn to the seventh page of "Microscopic Ninjutsu". ”

"See that symbol?" asked Izu.

Someone raised his hand, "It's the protective pattern, the protective pattern that maintains the seal." ”

Izuku nodded, "That's right, it's the Guard. But this one is different from the one you've learned before, it's a high-level one. The primary guard can only maintain three seals, and the advanced guard can maintain twelve, once the guard is broken and the ninjutsu collapses, then whether it is the ninjutsu sealed in the scroll or the ritual engraved in the formation, it will completely collapse, and even cause serious consequences. Do any of you know about the flooding of the Water Nation three years ago?"

Isu didn't wait for the students to answer, and said to himself, "After investigation, the cause of the incident was a flaw in the formation protection pattern engraved on the dam. At that time, the fifteen protective patterns of the 'Daqu Water Array' were not properly maintained, and there was a rupture, and one hundred and twelve seals lost the circulation of Zhuoluo, causing the formation to collapse completely, and the great river flowed backwards, flooding a nearby city and three small towns. At last count, 150,000 people drowned. ”

This shows the importance of pattern protection. ”

"In the past, the protection of the pattern was only slightly mentioned in the textbook, which was easy to ignore, but after this incident, almost all countries have regarded the 'protection of the pattern' as a key knowledge. Today, the first thing we want to learn is the knowledge of pattern protection. "Micro Ninjutsu", the so-called Microcosm, is to let you know that when Ninjutsu is dissected, it is like the human body, there are countless subtle but very critical 'organs'. ”

"...... below"

......

Teacher Isu's explanation was subtle, and although there were many things that Mo Lun didn't understand, he recorded them all and left them to find the answers after class.

This class lasted for four hours, and when the class director Yisu announced the end of the class, he could go through the knowledge of advanced pattern protection, and many details have not yet been explained, so I can only wait for the afternoon class to explain again.

As soon as he got out of class, he left the seventh class, and after leaving the 'church', he hurried out of the school and went straight to the tavern.

During the day, there are only a few people eating at the tavern, and if he usually returns, Morun will order a steak with a glass of sour lemon and enjoy it leisurely.

But now is not the time.

As soon as he entered the room, Moron closed the door and took out a prepared copy of the materials from the box where the materials were placed. The beaker is propped up, the material that has been ground into powder is poured in grams, the potion is prepared, and the soaked 'Nguyen's flower' is put into the medicine pestle and mashed, and then it is put into the beaker and gently poured in the potion.

The flames appeared, slowly heating up.

When the temperature rose to 60°C, Mo Lun picked up a gray stone the size of a soybean on the table and gently put it into the beaker. The stones melted into the water, and a mushroom-like gray cloud rose and dissipated with the wind.

When the liquid in the beaker was completely boiling, Morun poured the liquid into the silver bowl on the table, and the sound of rain came from the silver bowl. Moren took out a test tube, and there was a long red worm in the test tube, a bit like a leech, which was wriggling dishonestly at this time. Moren shook it hard, and the worm fell into the fluid, spreading like blood.

The silver bowl was lifted, and a cluster of flames appeared, and the fire began to heat the silver bowl, and in just a moment, the liquid inside boiled.

The water vapor evaporates, the liquid evaporates at a speed visible to the naked eye, and when it is thin to a certain extent, Mo Lun pours in a bottle of blue 'butterfly juice', and a strange scene appears, only to see the thin liquid in the silver bowl suddenly emerge dense with tiny red worms. These insects are exactly the same as the previous long worm, it is a refined version that has been reduced by a hundred times, countless fine insects greedily suck the butterfly juice, and the insect body quickly turns from red to blue with the swallowed juice, and when the whole body is blue, there is a small sound of "pop", and the blue insects explode, turning into a puddle of water droplets that are extremely fine, and the broken blue water droplets will hit the silver bowl with a snapping sound.

Like an effect, as the first bug exploded, the other small blue insects that smoked it also exploded, and one by one the blue water droplets bloomed in the silver bowl like fireworks.

"Poof... Bo Bo ......"

"Smack... Bang ......"

As if holding an instrument that played on its own, Mo Lun's eyes showed a slightly intoxicated look, and it lasted for five minutes before the sound in the silver bowl completely subsided.

Mo Lun's eyes recovered in an instant, and he picked up the last material, which was a silver crystal, the Half Moon Flow Crystal.

This small box of spars obtained from the Bauhinia caravan turned out to be one of the core materials of the "Rebirth Elixir", a half-moon flow crystal worth 80,000 world coins. This surprised Mo Lun at the same time, but also a little happy, you must know that this material is a rare one.

Mo Lun gently put the silver crystal into the silver bowl, and saw that the half-moon flow crystal had just touched the fine blue water droplets, and suddenly turned into a pool of liquid liquid, and in an instant, all the water droplets were submerged, and they flowed slowly like living creatures.

About ten minutes later, a moonlit silver glow emerged from the silver bowl, accompanied by a tempting fragrance.

Mo Lun jumped up in surprise, "Hahaha, it was successful, last time it was a fluke, this time it was really successful." This success was of great significance, and he had always been worried that he would not be able to master the refining of the "Elimination Elixir" in a short period of time. His time was short, only a year, he would be twenty years old, and by that time the meridians would be fixed, and all the potions would be greatly reduced or even completely ineffective.

In the end, he relied on the assistance of the chip, and after months of calculations and many attempts, he was finally sure that the refining was successful.

Calming his mind, Mo Lun poured the liquid from the silver bowl into a wooden bottle, screwed the cap, and all the silver glow disappeared in an instant.
