It took him 7 days to recognize all the objects. Every object had a bit of ki in them. But living had much more in amount. Rayhan was quite gifted in this department.

Next Karin trained him to be more nimble and fast. This got him started on the 'After image technique'. Rayhan was asked to increase his training weights by 2 times. It took him 1 week to create a single after image and after a month, he was able to leave 3 after images.

Lastly, He learned to do telepathy. It was relatively easy.

9 months later, Rayhan left Karins' tower with 100 Senju beans. He had exchanged 10 kilos of fish for a single Senju bean.

9 months of abstinence from sex had made Rayhan desperate during his stay at Karin's after tasting the forbidden fruit first time in his life but he could not miss this golden opportunity. So, he endured. After getting off the tower, he zoomed toward a particular town. He had fucked a 16-year-old girl name Fanfan previously there. He reached that town in 4 days and pounced on her like a hungry beast. Finally, after filling her with his sperm 10 times, he felt satisfied. The girl was shaking due to weakness after the sex. He stretched her ass the next day and enjoyed himself for a month with her. After much thinking, he decided to bring her back to Blackstone town

After reaching his hometown, he first arranged a place for her to live behind his mother's tailor shop. Fanfan was tasked to help his mother in the shop. His parents were happy that he had brought back a girl for himself and Fanfan would be beneficial for more business.

Life resumed its previous rhythm and months went by. During this period, he would occasionally go to the town and pound Fanfan whenever he was mentally fatigued with training. Fanfan helped his family make more money that in turn helped him buy medicinal baths. So, he was glad that he had brought her back. He had acquired pussy and wealth at the same time. This tranquil life continued for 4 more years when the peace was suddenly shattered.

One fine morning, Rayhan was having tea with his master. His master looked at the far distance and suddenly frowned.

"What is it? Master" Rayhan asked. He had a gut feeling that something bad had happened.

"Something bad is probably about to happen. We should hurry to the northern capital as soon as possible. We probably don't have more than 15 days. Every 50 years, the seal that closes the way to the demon realm weakens. This time it has weakened a year earlier. Something must have gone wrong" His master explained with a worried expression.

'Holy Shit! This is dangerous. I can not stay behind if my master goes. It would be morally incorrect. But thinking about fighting demons gives me the chills. As far as I remember if someone is killed by a demon then they won't be able to reincarnate and will be eternally doomed.' He thought.

"Master, What should we do then?" Rayhan asked.

"Naturally, We depart in 2 hours. We are among 10 big schools. We have a reputation to keep and also as martial artists we are the primary force against evil. Go and inform all the instructors and strongest disciples. Your senior brother will meet up with us in the northern capital." The master said.

"Okay. Master, I will gather everyone." Having said that he zoomed to the practice courtyard.

Half an hour later everyone had gathered.

"Demons have invaded. It's time to go to the northern capital. I won't say much. If you want to back out. Now is the time. Those who are going pack up your food and water for this journey. We need to reach within 15 days." Tiger hermit said in a single breath.

Not a single person backed out.

'Damn. These people are unexpectedly righteous. They are usually cranky and petty. But when it counts they seem dependable.' This thought ran through Rayhan's mind. He was rather impressed with these instructors. His father was also among them. This made him a bit worried but his father was at the very least as strong as him. So, he believed that he could stand on his own.

Their journey started after 1.5 hours and they zoomed through mountains and rivers. They were taking the fastest route possible. They traveled day and night. They ran for 10 hours a day at maximum capacity. Finally, after 13 days, they reached their destination. A strange type of aura had pervaded this place.

'It must be Demonic Ki' He concluded.

"Father, if you are ever seriously injured or heavily fatigued in a battle. You should eat one of these. It will fully restore you. This is a magic medicine. I brought it from Karin's sacred land. No matter how critical the injury is this will heal you up in seconds." He said to his father.

"Okay. I will keep these. You and I have to stick together. Don't veer off from our team. Soon 8 great families and 10 great schools will all arrive. Don't start a fight with anyone from another school. Lastly, remember our family has a long history in the martial arts world. Each of our ancestors has died for a just cause. My father, your grandfather died last time the seal had opened. If I die in this battle take care of your mother. But of course, I won't die that easily." He explained and smirked.

Rayhan was a bit surprised to learn that he came from a long line of martial artists.

"As long as you have those beans, even Yama won't be able to take you to the afterlife. Dad, there is no need to worry about Mom." He said.

"Okay. Okay. I got it. Since you have already reached the stage of ki externalization, I will teach you our family's martial arts. It is effective against demons. It was created to fight demons in the first place. It will probably take 10 days for the seal to fully weaken. With your talent, you will probably grasp this technique within 10 days. Let us find a quiet place and train." Ray said.

After that under his father's instructions, Rayhan started to train on "Demon killing fist". The concept of this martial art was simple. However, fully mastering it would take decades. The basic idea was to slightly alter the nature of your ki and make it paler. When it became sufficiently pale, the lightning spark would be infused in the ki. This lightening nature and the pale-colored ki were extremely effective against demonic ki.

Rayhan started training non-stop. When his father asked him to not overdo it. He showed him the miracle of the Senju beans. He trained non-stop for 7 days with the help of 14 Senju beans and was finally able to infuse his ki with lightning sparks.

Almost all the top martial artists in the world had come and encircled the capital of the northern region. Their goal was very simple. It was not letting a single demon invade earth. There was another line of defense 20 kilometers behind the front lines where 1st class and 2nd class martial artists were stationed.

The stage was set and the madness was about to descend.
