Akaza was slain, which also meant the mission was successfully completed.
On the way back, Lin Che asked Hestia for the red envelopes to update and upgrade the Blessing.
Then he updated Kocho Kanae's Blessing and upgraded it to Lv2.
Upon returning to the Demon Slayer Corps Headquarters, Lin Che began training the Kocho sisters again.
However, after less than three days of training, the Flame Pillar, Tanjiro, Inosuke, and Zenitsu also arrived, requesting that Lin Che train them as well.
Lin Che did not refuse and readily agreed.
After all, training three is training, and training a group is also training.
Thus, under his rigorous training, the strength of the seven grew rapidly.
Tanjiro, Inosuke, and Zenitsu, the three youngsters, reached Pillar level strength after only half a month of training.
This made the other Pillars of the Demon Slayer Corps unable to sit still, and they all requested Lin Che to train them.
Lin Che also agreed to them and began putting them through devilish training.
If they don't train to death, then train them until they are on the verge of death!
Tired, exhausted, body can't take it anymore.
One healing magic, and continue training!
Just like that, the strength of the Pillars of the Demon Slayer Corps, as well as the three youngsters Tanjiro, grew rapidly.
In addition, Lin Che was not stingy and taught the Fighting Spirit cultivation method from The Dungeon World, along with the three major sword styles, to all the Pillars and the three youngsters Tanjiro.
In his opinion, these guys would all be members of Hestia's Familia in the future, so teaching them in advance was fine.
Moreover, he had already obtained Roxy's permission to freely teach the Fighting Spirit cultivation method and the three major sword styles to others.
The Pillars of the Demon Slayer Corps were all overjoyed upon receiving the new cultivation methods.
They were like tireless ironmen, training their physical strength and developing their potential during the day, and cultivating Fighting Spirit and the three major sword styles at night.
In just one month, the martial arts of all the Pillars reached the highest realm, and their combat power reached the level of Upper Rank One Kokushibo.
The strength of the Kocho sisters, Shinobu Kocho and Kocho Kanae, even reached the level of Yoriichi Tsugikuni.
The strength of Tanjiro, Inosuke, Zenitsu, and Kanao Tsuyuri also reached the Pillar level.
Even Nezuko's strength reached the level of an Upper Rank demon.
The Nezuko here had the strength of an Upper Rank demon without going into a berserk state and losing her sanity. If she were to go berserk, she could even fight against Kibutsuji Muzan.
Lin Che was very satisfied with everyone's improvement over this month, so he spent another 500 points to purchase the magic "Dia Frate" from the Chat Group Mall!
That's right, it's that most abnormal healing magic from The Dungeon World.
This is the magic of Amid Teasanare from the Dian Cecht Familia.
Amid is called the Saint of the Battlefield precisely because of this magic.
This is the highest level of healing magic, possessing the characteristics of healing wounds, restoring stamina, expelling toxins, and dispelling curses simultaneously.
It can also be used to apply recovery, detoxification, and curse removal effects separately, and can affect multiple people with a continuous effect.
Before coming to the Demon Slayer World, Lin Che had accumulated a total of 10460 points.
Purchasing the healing magic "Dia Frate" used 500 points.
Purchasing the resurrection magic "Dia Euhlius" used 1000 points.
Having been in the Demon Slayer World for nearly three months, he signed in for 710 points.
He now has 9670 points remaining.
These points cannot be used carelessly, as bringing people from other worlds to Orario will require points.
100 points per person, ten people is 1000 points!
Although it's a lot, Lin Che doesn't feel the pinch!
When he was still an ordinary person, it was Luo Hao and Hestia who helped him grow.
Now that he has grown, it is time to repay the two women.
No matter how many points he spends on the two women, he will not feel the pinch.
Because without them, there would be no him today.
As for the others in the Chat Group, Lin Che will also help them.
For example, now, helping Shinobu Kocho solve the demon problem.
Poor, one takes care of oneself; prosperous, one helps the world.
Although Lin Che is a very selfish person, he is never stingy towards those who have helped him.
Before, he had no ability, so he focused solely on pursuing strength, using any means necessary!
Now that he has the ability, he will not shirk.
After purchasing the magic, Lin Che had Shinobu Kocho call the Head of the Estate, Kagaya Ubuyashiki.
Then, under the curious gazes of everyone, he began to chant.
"Drops of healing, tears of light, eternal sanctuary, summon the medicinal melody here."
"Three hundred and sixty-five melodies."
"The calendar of healing will save all things."
"Then, come forth, break the evil."
"Bury wounds, send away sickness."
"Send curses to the other shore, send them to the pivot of light."
"In the name of God, I heal."
"Dia Frate!"
As the chant ended, a green light appeared in Lin Che's hand, enveloping Kagaya Ubuyashiki.
The next moment, the curse on Kagaya Ubuyashiki was removed.
Not only that, the injuries on his body caused by the curse were also completely healed.
After the treatment, Kagaya Ubuyashiki's eyes, which were previously blind, opened again.
After adjusting to the slightly dazzling sunlight, he finally confirmed that he could see again.
Not only that, his body had also completely recovered.
"I've recovered, I can see!" Kagaya Ubuyashiki repeatedly looked at his hands and all the Pillars present, weeping with joy.
"Amazing, the Master has recovered!"
"As expected of the magic that kills Pillars, it's incredible!"
"That's right, we should all thank the Pillar Killer."
The Pillars were also overjoyed, then they all turned and bowed to Lin Che.
"No, no, no, you should just call me Lin Che. 'Pillar Killer' sounds awkward, like 'Pig Killer'." Lin Che waved his hand, joking with everyone.
Upon hearing this, everyone also burst into laughter.
To celebrate the Master's recovery, the Pillars decided to celebrate.
Thus, the Demon Slayer Corps Headquarters became incredibly lively that night.
Everyone made a lot of delicious food and happily drank and ate meat together.
Lin Che really liked this atmosphere and also drank a lot.
Although he used Godly Power to expel the alcohol, the Godslayer's physique was incredibly strong, coupled with the skill "Infinite Regeneration," which meant he couldn't get drunk at all.
