Mu Chen has been familiar with this Dan recipe more than a thousand times, and he knows every detail well.

After all, it's a matter of foundation.

Half an hour later, the first furnace of wood dust built the foundation to restore the pill was baked, nine pills, each of which was full of color, faint purple light appeared, and the danxiang overflowed and filled the entire alchemy room, and the Dan pattern emerged, slowly absorbing the aura of heaven and earth, and the breath of heaven was rich, exuding a faint oppression.

The best foundation to restore the Dan......

Under the best, only one can become a Dan, and only the best can become nine Dan.

The first furnace was successful, and the puppet boy next to it put it into the Dan bottle and sent it to the outside world.

The outside world caused a sensation:

"Nine? How can it be nine? Doesn't it mean that one furnace can only become one?"

"I don't know what the effect is, will it be inferior to Lingyun refining. ”

"Whoever comes first to test the properties. ”

"I'll do it. ”

"Why don't you wait for a while, let's wait for the spirit rhyme to be successfully refined, and then draw conclusions after comparing the two. ”

Half an hour passed again, and Lingyun's one Abutment Restoration Pill and Mu Chen's nine Abutment Restoration Pills were sent out together.

After comparing the two, Mu Chen won completely, and the nineteen foundation restoration pills were snatched up.

Wood dust is one furnace every half an hour, nine pieces of Cheng Dan, and each refining eight furnaces rests for two hours.

Lingyun has one furnace per hour, one Cheng Dan, and rests for two hours for each refining furnace.

At the moment of rest, the concentration of aura in the alchemy room is extremely high, ensuring that wood dust and aura can recover as quickly as possible.

Twenty-four hours a day, except for the recovery of aura, the rest of the time was spent refining the Restoration Pill, and in one day, Mu Chen refined two hundred and eighty-eight pieces, each furnace was successful, and each furnace was nine superlative.

The best restoration pill, each one can restore a complete layer of foundation.

On the second day, Lingyun still wanted to continue refining the Restoration Pill, but was stopped by the Dan Master of the Spirit Master Pavilion and forcibly let him rest.

The three furnaces of Lingyun refining and restoration pill will fail two furnaces, and there is only one Chengdan, which is completely disproportionate to the efficiency of rainy nights.

In other words: it's a waste of material......

The materials are so expensive, so nervous, how can the Spirit Master Pavilion let Lingyun go to waste.

Lingyun walked out and knew the success rate of Mu Chen, Cheng Dan rate, and was embarrassed for a while, and after saying goodbye to Ye Lao, he went to the Demon Beast Mountain Range to look for Niu Er and the others.

At the end of the two days of refining, Mu Chen walked out of the alchemy room with a pale face.

Originally, it was thought that the number of monks outside the alchemy room would decrease, but now instead of decreasing, there are more of them.

Looking at these eyes in front of him that were eager to penetrate and shimmer with the light of hope, and glanced at Ye Lao, without the persuasion of the Spirit Master Pavilion Dan Master, Mu Chen resolutely returned to the alchemy room and continued to refine the Restoration Pill.

There are too many monks who need to restore the abutment, but only Mu Chen can refine the Abutment Restoration Pill......

Wood Dust is their only hope, and Wood Dust doesn't want to disappoint them......

After refining more than 200 foundation restoration pills, Mu Chen's spirit was not good, his spiritual sense was exhausted, his muscles trembled slightly, and he fell to the ground and fell into a coma.

Ye Lao's eyes were filled with tears, and he returned to Canghai Academy with the unconscious wood dust in distress.

This kid, no one asks you for anything, why do you fight so hard?

At five o'clock in the morning of the second day, Mu Chen woke up from his coma.

"Brother Muchen, you've finally woken up. ”

"We're scared to death. ”

"Brother Muchen. ”

The opening of the second class of Niu in the dormitory is concerned.

Looking at the faces of Niu Er and the others, a smile appeared on the corner of Mu Chen's mouth:

"I'm okay, how are you?"

"Brother Muchen, they are all minor injuries, and they are not in the way, Brother Muchen, this time we have harvested ten foundation building peak demon cores, more than a hundred foundation building late stage demon cores, and a total of nine hundred and thirty high-grade spirit stones. ”

Niu Er reported what he got this time, and he harvested 900,000 low-grade spirit stones in three days.

"So much? How did you do that. ”

"It's the same as last time, the formation is lured, there are two puppets who build the pinnacle of the foundation and are tireless, and they have the greatest meritorious service, the only drawback is the Fei Ling Stone, after deducting it, Brother Muchen, you can still get thirty high-grade spirit stones. ”

"So good. ”

"Uh-huh. ”

"Cultivate with all your might, and strive to be able to advance to the late stage of foundation building within a year. ”

"Uh-huh. ”

Everyone replied in unison.

"What time is it, is it time for class?"

"At ten o'clock, it is estimated that it can catch up with the Ten Minutes Spirit Gathering Array. ”

"So what are you waiting for? Hurry up, don't be late. ”

Mu Chen got up with a grunt, and a group of sixteen people ran outside.

At the end of the morning class, Mu Chen went to the Alchemy Department to apply to Ye Lao to continue refining the Foundation Restoration Pill.

Mu Chen's pain of broken base has been experienced personally, and Mu Chen can't go any further, although seven days is not long, Mu Chen doesn't want them to continue to wait.

"I'll plan a secret room for you, and you can refine it in the academy. ”

Ye Lao pondered for two seconds and came up with a compromise solution.

Frequent visits to the Spirit Master Pavilion are not a solution, and they will always be discovered by those who have a heart.

"Uh-huh. ”

After waiting for two minutes, the first batch of materials arrived, and the wood dust began to be refined.

From afternoon to evening, Mu Chen refined one hundred and forty foundation platform restoration pills, all of which were handed over to Ye Lao.

The aura in the alchemy room was abundant, and Mu Chen simply did not return to the dormitory, but directly meditated in the alchemy room to restore the aura.

From four o'clock in the morning to six o'clock, the abutment was built for Ye Lao's pregnancy and cultivation to restore his aura; from six o'clock to twelve o'clock, the learning knowledge was confirmed by the experience in his mind; from afternoon to evening, the wood dust disappeared, and no student saw him.

Although refining the foundation building platform restoration pill, Mu Chen's class plan has not been broken.

Every day, every minute, every second is arranged very tightly by wood dust.

Seven days have passed, Niu Er led the team to the Demon Beast Mountain Range again, and Mu Chen was still refining the Foundation Restoration Pill.

The Linghu Lake in the dantian is empty, and when it is restored again, the area of the Linghu Lake will be a little larger.

Half a month, Mu Chen obviously felt that the aura lake was one-tenth larger, and the second foundation had accumulated rhizomes.

As long as the area of the Wood Dust Aura Lake is doubled, the second foundation can be sprayed out, and it will take half a year at the current rate.

The high-intensity days lasted for a month, and the wood dust disappeared for a month.

After a month's effort, Mu Chen will understand the puppet experience in his mind fifty percent, and the puppet refined is stronger, according to the current progress estimate, Mu Chen will be able to fully understand the puppet experience in two months.

After penetrating the experience of fifty percent of the puppets, Mu Chen discovered a secret: the puppet experience recorded a powerful puppet in the foundation building period, which is said to be completely capable of wrestling with the demon beasts in the early and even middle stages of Jindan.

If Mu Chen can be refined, then it proves that Mu Chen's second-order puppet profession is no longer doubtful and reaches the peak, which is a hidden assessment.

Mu Chen was ready to wait for the matter of building the foundation platform to restore the pill and the matter of the natal magic weapon to come to an end, and then he began to refine this puppet.

Today, Mu Chen came directly to the alchemy department after class, entered the alchemy room, looked around and had doubts in his heart, what about the materials for refining the restoration pill?

When he was puzzled, Ye Lao walked in with a smile on his face.

"Mu Chen, let's put aside the matter of refining the foundation building restoration pill for a while. ”

"What's the matter, Ye Lao, I can still hold on. ”

Mu Chen was puzzled.

"The Zhujitai Restoration Pill is enough for the time being, and you can't delay your learning, so let's do it, in the future, you can take the time to refine one day every seven days, by the way, this is the harvest of refining the Zhujitai Recovery Pill this month. ”

"Uh-huh. ”

Mu Chen took the probe spirit sense, huh, nine top-grade spirit stones, three thousand high-grade spirit stones?

"Ye Lao, why are there so many?"

"Mu Chen, compared to your efforts, this little gain is already very little, take it. ”

"Well, then I'll take it, Ye Lao. ”

"Go and get busy with your business, Mu Chen, remember to ask me if you encounter any problems above the alchemy and formation, I have been in the alchemy department. ”

"Okay, Ye Lao. ”

Mu Chen left, and found Niu Er to come to the refining department with him, and it was time to solve the matter of everyone's natal weapons.

"Brother Muchen, I thought you forgot. ”

Niu Er scratched his head and spoke embarrassedly.

These days, Mu Chen almost doesn't go home at night, and when he finally comes back, he falls asleep, and everyone is embarrassed to ask about the natal weapon.

"I haven't forgotten, but you'll have to cooperate with me for a while to make sure that the natal weapon can communicate with your mind and command. ”

"Uh-huh. ”

"By the way, Niu Er, do you want to build the natal artifact in the early stage of the foundation? and then conceive all the way to the peak? Or will I directly build it for you to the peak?"

"Brother Muchen, is there a difference?"

"The natal weapon in the early stage of foundation building, your materials are enough, but if you want to be promoted to the peak, you still need to pay me 200,000 spirit stones for the material fee, as for the difference, it is nothing more than the degree of mental instruction.

There is also a natal magic weapon at the peak of foundation building that is nearly ten times more powerful than the early stage of foundation building, and infusing aura may be able to directly seriously injure a demon beast at the peak of foundation building. ”

"It must be the peak, what else do you want, Brother Muchen, this is all the spirit stones on my body, I will give them to you, and I am thinking of a way to do the rest." ”

Niu Er took out a total of 100,000 spirit stones.

"Here, add my 150,000 spirit stones, and go buy the materials on the paper. ”

As he spoke, Mu Chen handed Niu Er a storage bag and a note.

"Okay, Brother Muchen. ”

......

......

Before refining, Mu Chen recited the secret of purifying his heart, restored to the best state, took out the drawings and materials one by one to check, compare, and familiarize.

An hour later, the wood dust opened to refine the fire wood and the pearls.

The difficulty of the fire and wood pearl is to fuse the fire attribute ore with the wood attribute ore, and if you are not careful, the fire attribute ore may destroy the wood attribute ore, so that it cannot exert its due strength.

Finding the right balance between the two is the most important thing.

The wood dust heart is divided into two uses to smelt the peak fire ore and ironwood ore at the same time to ensure the unified quenching of the flame strength, and remove the impurities as much as possible, and the wood dust is put into the earth crystal, gold crystal, and crystal stone in turn.

The five elements of materials in the instrument are mutually reinforcing, Huoyan and Ironwood carry out preliminary fusion, and then the wood dust keeps placing materials inward, adjusting the flame intensity, and the cumbersome operation makes Niu Er stunned.

At six o'clock in the evening, Mu Chen shouted in a low voice:

"Niu Er, cut your wrist and take nine drops of blood. ”

"Uh-huh.
