This story focuses on a person named Lou Yi. He is an ordinary human who performs activities that ordinary humans do. However, his true identity is the savior of the world when the world is on the verge of collapse. When the world is on the verge of collapse, someone saves the world and makes the world peaceful again, but after that incident, the unknown savior becomes the most mysterious person in the world and that person is Lou Yi.

Lou Yi was also not an ordinary human, he was an immortal human who could not die, he obtained that immortality after meditating and cultivating for decades. because of his immortality, he became a witness to history for hundreds of years. Once upon a time, the world was on the verge of collapse again and needed Lou Yi's power as the savior of the world again and her adventure as a savior begins again. Lou Yi started his adventure today and the first step he took was to pick up his equipment such as swords and other tools. Lou Yi's sword is the oldest and strongest sword in history.

Then, the second step he took was to enroll in a special Academy for magic and physical strength?? Yes, because it turns out that after the world is on the verge of collapse again, the countries of the world are working together to establish special academies around the world to solve the world's problems. When someone enrolls in this academy, they will take a special test before entering the academy to determine their respective classes and strengths. Classes in this Academy are divided into three, there is a high class consisting of students with S and A grades. Then, the middle class consisting of students with B and C grades. Then, the lower class consisting of students with D and E grades.

Lou Yi's goal of entering the academy is different from others, he entered the academy in order to form good relations with many people and also know developments and information about this world.

The day of the exam to determine Lou Yi's strength and class began, he took the exam that included physical strength, magic power, and duels with instructors. Lou Yi successfully passed the physical strength and magic power test with perfect marks, it was time for the dueling test.

Lou Yi duels with the strongest instructor in the school. The strongest instructor in that school is named instructor the strongest instructor in the school was named instructor Wen Guang and it turned out that Wen Guang was Lou Yi's friend and student. it turned out that previously Lou Yi was a world-renowned teacher and he was the strongest teacher, but his career had been ruined due to being slandered by teaching his students evil magic, but it was just a lie so that Lou Yi couldn't produce a strong disciple who could protect the world from all the bad things that would happen so that those who had slandered Lou Yi could carry out their evil plans for world domination.

Wen Guang was surprised when he met his teacher again and Wen Guang apologized that he couldn't help anything when Lou Yi's status as a teacher was about to be destroyed. Lou Yi who saw that his student could become a successful person was proud and he said that the student doesn't have to apologize because it wasn't his fault.

They finished talking and they started the duel test, this duel became one of the most powerful duels in the history of the academy, but the victory of the duel could not be determined. While the duel was in progress, Inspector Wen Guang said to Lou Yi: "Teacher, what is your current level of strength?", Lou Yi replied: "I don't know because I haven't used magic in a long time." The duel continued, everyone there was shocked and amazed when they saw the duel between teacher and student (they didn't know that Lou Yi was Inspector Wen Guang's teacher).

Not long, Wen Guang's magic power and Qi were exhausted and Lou Yi took advantage of this opportunity to win the duel and Wen Guang lost. The people who saw it started to wonder, who was the person who had defeated the strongest inspector in the academy and how he did it. Then, Lou Yi helped Wen Guang to stand up and said: "Wen Guang, you have become a stronger person now." Wen Guang finally couldn't hold back his tears at the last moment and hugged Lou Yi, Wen Guang was happy to finally meet the person who had helped him to stay alive.

However, their happiness stopped there after they met again with the leaders of the organizations who had dropped Lou Yi's status as a teacher. They laughed at Lou Yi who was now a weakling who enrolled as a student in a special academy. Wen Guang who wanted to beat them up was stopped by Lou Yi because that would only make things worse. The leaders of the evil organizations also said that they wanted to see the ruined Lou Yi as a student in that special academy. The leaders of the evil organizations went and gave gifts to everyone present, namely the 5-star spiritual beast, the nine-tailed fox.

Those who were there were evacuated as soon as possible by the school's security officers, but there were a few people who didn't go for the evacuation, namely Wen Guang, Lou Yi, Ye Wan, and Ye Wu. They worked together to stop the movement of the nine-tailed fox, but it wasn't easy considering that the summoned nine-tailed fox was a five-star spiritual beast. They were getting more and more overwhelmed as they fought with the fox, but hope had not been lost. Lou Yi, who previously wanted to look like a weakling, finally let out a bit of his strength and after Lou Yi used one of his weakest moves, the fox immediately lost.

The fox's defeat also made Lou Yi get the 5-star nine-tailed fox card and the fox turned into his human form and made Lou Yi its master. Lou Yi could make the fox his servant if Lou Yi made and signed a contract with the fox for a token fee. Lou Yi who had never used his token in his life also had a lot of tokens so he could make a contract with the fox easily. Lou Yi who had a contract with the fox gave him the name "Tama", Tama was happy to get a good name.

Back to the story, after they defeated the fox and Lou Yi made the fox his servant. The fox that had been Lou Yi's servant was turned into a card again so as not to attract attention. However the news quickly spread and soon made them famous in all circles. This news also spread to the leaders of the evil organization that summoned the fox, they were annoyed that their plans had to be ruined. They didn't expect that the strength of the five-star fox couldn't beat the might of the world's strongest former master. Those who can't accept that are again planning something that is definitely more dangerous.

Returning to our main character, Lou Yi and the three people who had fought together against the fox became acquainted with each other. Ye Wu and Ye Wan, the two twin girls of the Ye family who helped fight the fox were amazed by Lou Yi's strength even though she was someone who applied to become a student at the academy.

However, Lou Yi didn't care about it and tried to get acquainted and establish good relations with the two twin girls. The three of them easily became friends, but Lou Yi looked at Wen Guang who didn't say a word. Lou Yi also asked Wen Guang and Wen Guang said that he was an inspector and he was afraid that the two women would be afraid to talk to him. Lou Yi also helped Wen Guang introduce himself and said that Wen Guang wanted to be friends with the two girls, they accepted the friendship and the four of them became friends. Then, because it was too late, they decided to go back to their respective homes and meet again during the new student acceptance ceremony.

On the day of the new student acceptance ceremony, Lou Yi, Ye Wu, Ye Wan, and Inspector Wen Guang caught the attention of the academy. They were surrounded by many new academy students who were amazed by their strength that could defeat the five-star fox, but there was one thing that intrigued them the most. Who got the five-star fox card? They were curious about it because the five-star fox card was very hard to get. Lou Yi, Wen Guang, and the two twin girls from the Ye family also chose to keep it a secret in order to avoid any trouble that might occur. The four of them said that the nine tailed fox card was swept away by the wind so that no one got it.

"Who is Lou Yi here?", someone suddenly appeared

It turned out that that person was the vice president of the academy, Yun Kang. Yun Kang was a person who was greatly feared in the academy due to his strict attitude, but his attitude changed when he met Lou Yi.

"Master, how did you get here as a disciple?" said Yun Kang

Everyone there was also surprised to hear Yun Kang addressing Lou Yi as his master because everyone knew that Yun Kang master was a former famous and strongest teacher in the world.

After all, the famous and strongest teacher came out of the world of magic and martial arts for more than 200 years. Many new generations also don't know the name of the strongest and most famous teacher because it is the world's number 1 secret so that the security of the secret need not be doubted.

The new generations are also actually not allowed to know about the famous and strongest teacher, but many families tell the story to their descendants in secret. The news that Lou Yi was the master of vice president Yun Kang quickly spread to all circles, from commoners to world leaders. People from organizations that want to rule the earth also heard this news which made them shocked and frightened. Those bad guys didn't expect that Lou Yi would come back to save the world again. Then, the leaders of the evil organizations began to plan large-scale meetings.

There are 3 big evil organizations that will come to the meeting, namely the Black Sand Organization, the Illuminati Organization, and the Freehouse Organization. They would discuss the topic of Lou Yi's return which would bring disaster to them. Even though the three organizations didn't have a good relationship with each other, they decided to make a temporary alliance to face Lou Yi.

Returning to Lou Yi, Lou Yi knowing that he would soon be targeted by his enemies and decided to take Yun Kang and Wen Guang to a hidden place in his former Sect, namely the Wuda Sect. The Wuda Sect itself was the former strongest sect in the world and this sect always held the number one rank before being destroyed because Lou Yi had to leave the world of magic and martial arts. Yun Kang and Wen Guang themselves had never come to that hidden place because only Lou Yi knew.

Lou Yi brought the two of them there because it was a very safe place to discuss. After they felt safe, Lou Yi asked a few questions about the things that happened after Lou Yi left the Wuda Sect and the world of magic and martial arts. Yun Kang and Wen Guang explained that their friends were scattered all over the world, many of them holding high positions in well-known organizations.

Yun Kang and Wen Guang said that some of them held high positions in the world protection organization and other organizations. For example alchemy organizations, swordsmanship organizations, magic organizations, etc. There are also those who go on adventures all over the world to gain a lot of fighting experience and there are also those who stay in the forests to meditate for decades.

“Master, what did you do for 200 years?”, They both asked

"Doing the activities that an ordinary human would do.", Lou Yi said.

The two of them were shocked that the former leader of the world's strongest sect had only carried out ordinary human activities for 200 years.

"Hey, don't underestimate the activities I do, the activities I mean are making pills, making new magic, cultivating, etc.", Lou Yi said.

"F*ck, that's not an activity carried out by an ordinary human, Master, could it be that master's judgment has only gotten worse during these 200 years!?”, replied Wen Guang and Yun Kang.

Lou Yi said: "Maybe it's because I haven't seen my beautiful female disciples in a long time."

"Master, you look very lonely without your female students...", they said.

"I want to meet them as soon as possible, I miss them", said Lou Yi sadly.

After discussing other topics, Lou Yi and his students began to discuss about the problems they would face. Lou Yi's two disciples tried to find a safe way, but Lou Yi didn't want that. Lou Yi didn't want to find a safe route if it would only cost them. Lou Yi then asked them if there were still other students in the school or the city and they both said that there were only the two of them in the city.

The two of them said that almost all the disciples left the city because they were all trying to make achievements to protect the world that Lou Yi had protected. They all also try to restore Lou Yi's position so that he can be accepted again by the world even though it is not easy. However, this has not yet been fully realized. Why? Because the evil organizations that hate Lou Yi are also blocking Lou Yi's disciples so that their greatest threat doesn't destroy their plans a second time. Some of those evil organizations also arrested the female disciples of Lou Yi, some of them were imprisoned for decades, some were tortured, and some were enslaved. Lou Yi who heard this was very angry and the two disciples tried to calm him down. They said that the students who were treated like that weren't too many because most of them had already attained high positions in the world's most important factions.

"Oh, don't I also have some male students, how are they?"

"Sorry, Master, we don't know about all of them, we only know about Li Guang, Li Ge, and Shi Wuran", they replied.

Lou Yi also felt calmer because the news of his five male disciples was known, the remaining two were unknown.

Lou Yi: "So how are the three of them?"

Wen Guang and Yun Kang: "Emmm.... The three of them went to war against the Black Sand Organization, but the outcome of the battle is unknown."

Lou Yi was immediately shocked and didn't know what to say. It was natural that Lou Yi was shocked and didn't know what to say because the Black Sand Organization was one of the strongest evil organizations in the world.
