"Kaio-ken draws out the maximum power of body and mind to amplify the power and speed of the user. Now I will tell you the more technical aspect of the technique and you try performing it." King Kai added.

15 days later, Rayhan's Ki exploded for a second but after that, he slumped to the ground.

Months passed like that Rayhan managed to master kaio-ken time 2. Initial activation of Kaio-ken enhanced his powers drastically whereas kaio-ken times two outright doubled the power. and speed.

According to King Kai, He could only activate Kaio-ken times 2 with a 9,000 power level. To activate kaio-ken times 3, he would at least have to have a power level of 20,000 without actually damaging the body. Although Rayhan had the Senju beans, he didn't intend to cross the limit as of yet.

Rayhan found out that trying to keep kaio ken's red aura in check did wonder for ki control.

Two months later and Rayhan was able to look like a normal person while using kaio-ken times two.

8 months later, he was able to keep the ki restrained within his body.

His power level had already become 16,000 by the end of the year.

His days started to pass with endless training. King Kai didn't send him back after 3 years. King Kai had probably forgotten or King Kai was just lonely up here. So, Rayhan stayed for a total of 10 years. During this time, whenever he missed his family he would request to talk to them through King Kai. King Kai didn't mind his occasional requests. So, he would connect Rayhan to them.

His power level had reached 64,000 which allowed Rayhan to go Kaio-ken times 4. Naturally, Rayhan had already perfected the kaio-ken time 4 to the point where he could hide his ki somewhat while using it.

When he reached 90,000 he would be able to use kaio-ken times 5 without really harming the body. It would just exhaust the body faster.

One day, Rayhan took the chance and asked King Kai about god ki.

"God ki, you say?" King Kai thought and replied, "God ki is an exceptionally pure quality of ki used only by divine beings. Because of this, it is impossible to sense by beings in possession of ordinary ki."

"Is it possible for me to gain god ki?" Rayhan asked hopefully.

"Of course but you will have to become the guardian of someplace or be like kami of your earth. These people have the tiniest amount of god ki which enables them to sense god ki from higher-level deities. However, most mortals are unable to sense god ki" King Kai said.

"So I need to become Kami to gain god ki, huh?" Rayhan mumbled to himself.

"It won't make you any more powerful than you already are. It will just give you the ability to sense its presence in other beings. Kami's of planets have this ability. But is he powerful?"

'Damn even if I could just get the ability to sense god ki. It would be beneficial in the future. I already know the rudimentary way of trying to get god ki. But I can't tell that to King Kai, can I?' he thought.

"Hey, King Kai. If a vacancy for Kami or something similar pops up. Can you recommend me? Also, can Kami retire or is it for life?" Rayhan asked.

"Yeah sure. If you just want the ability to sense god ki then why become a kami and be restricted. The best way would be to become a special envoy and work for the other world." King kai said.

"There is such a good thing?" Rayhan asked.

"Yeah. Special Envoys have become a thing of the past but that doesn't mean you can't become one. But you will have to travel around some time to do some jobs for me in the mortal world. You will be considered as god's agent in the mortal realm." King Kai said.

"Can you make me one now?" Rayhan asked.

"Of course not. This will have to go through multiple procedures first and after grand kai approves of it. You can come here to sign a contract." King Kai said.

"Hmm, can you apply for it now?" Rayhan asked in a hurry.

"Sure," King Kai said.

After a ten-year-long stay at King Kai's, Rayhan had returned to the mortal world. He came out on Kami's lookout. So, he naturally met Karin first. After drinking tea with Karin he bade him goodbye and returned home.

In the serene valley, a small kid about 5-6 was playing around with a beautiful lady. A handsome young man suddenly appeared in front of them.

"Honey!" the woman exclaimed and ran into his arm.

"Hehe, I am back." Rayhan said.

"You are not going anywhere for another 100 years," Annin whispered with venom in her voice. Rayhan suddenly felt dread in his heart after listening to his wife's words.

"Okay," Rayhan replied.

After being berated by Annin he met his little son who looked exactly like him.

"Hey little guy, guess you don't remember me, do you?" Rayhan carried him on his shoulders.

"Hmph! Who is the little guy? I am already so big." Andy replied.

Rayhan remembered Annin from a long time ago and laughed looking at her.

Rayfan was away at the academy. So, he was not able to meet Rayfan.

After that, he met Fanfan and his parents. His parent's power level had reached 500 but they were incredibly old. So they would not be able to hold on much longer.

His father had elevated the super-human transformation to times 3.

He first asked his parents again, if they wanted immortality but they wanted to pass on to the other world. So, he proposed the idea of them living a new life in the other world. The other world was another journey altogether. It was like a fresh start. Also, the other world was an incredibly interesting place where one would get to see different things. His parents naturally agreed to this.

He stayed home for 2 years during which he used multiform techniques and send half of his clones to train in the demon realm. Of course, the other half would create other clones and train using the weighted clothes there which would be effective for his training at this point. If he wanted to train to higher heights. Either the next step was a gravity machine or using clones to train in higher gravity of the demon realm with weighted clothes.

He kept a clone at home at his parent's beck and call. He accompanied them for 2 years.

He told them that it was better for them to enter the other world together. So, he suggested taking them to Kami and following him to the other world rather than passing away from a natural cause. They agreed. Rayhan's family gathered along with Okami and Zabra to celebrate his parents going into another world. Rayhan had pulled some strings and King Kai had promised to give his parents comfortable jobs in the other world.

After reaching the lookout, Rayhan said one last goodbye to his parents, and after that Kami disappeared with them.
