Rayhan reached the entrance to another dimension after flying for 3 hours. He took off his weighted clothes. He meditated for 1 hour. He readied his stock of Senju beans and finally entered with a huge vat. It was a tunnel that went underground. He walked for 3 hours in darkness using his ki sense. Finally, there was a light source. When he reached the end of the tunnel, he saw a large hall. In the middle of the hall was a fountain. In front of it was a black panther, quietly sleeping. He would not want to wake it up needlessly. If he could he would not want to fight that monstrosity. He had determined its power level to be around 310. Since the cat was sleeping, its aura was not restrained. So, it was pretty easy for Rayhan to gauge its battle strength.

He slowly entered the hall. Rayhan was bad at sneaking around but he could hide his ki to the extent where another martial artist with ki sense might think of him as a normal person. Although mind-calming tea had helped him a bit in this aspect. The greater contributor was his innate gift in this area. He could simply fly without making any sound on the ground but that would expose his ki signature. He slowly took steps toward the fountain but due to his inadequacy in sneaking around, the cat opened its eyes. The cat stared with bafflement because it had not expected a human to come.

"Mortal, This is not a place that likes of you can enter. Go back and this lord shall forgive you." The panther spoke in a high and mighty manner.

Since Rayhan had restrained his ki to the level of a normal person, the panther could not detect that he was a martial artist. He was quite amused with this panther's way of talking.

"Naturally, I am here for that water. I will drink some and get lost. How about it?" Rayhan would not want to fight uselessly against a dangerous foe.

"That is not possible. If you don't go back. I don't mind eating another human." The panther said in a bit of a threatening manner.

"Oh. Hehe. Why don't you try? Let's see who eats who." Rayhan said in a mocking tone.

"You didn't listen to me. Now, face the consequences." growled the panther and slowly stood up and pounced toward Rayhan.

When the panther was 1 meter near Rayhan, He slightly crouched and punched with all of his might. The panther had not expected Rayhan to be a martial artist. So, the cat was taken by surprise. Thus, the full power punch supplemented with is gloves that had steel spikes connected with the panther's chest. The panther flew away like a broken kite and hit a wall 50 meters away.

It stood up and accused, "You liar. You are a martial artist."

"I never said I was not" Rayhan smirked. He had done quite severe damage to the panther in the first hit. Now, he was 100% confident that he could take out the panther from the fight if he went all out.

So the confrontation began and it ended after 10 minutes. Surprisingly, the panther had pushed Rayhan a bit too much in this fight. the panther was knocked out in a corner. Rayhan took out a small 50 ml container and drank 100 ml. Immediately, his appearance started changing and he looked like he was 20. After that, he filled the vat, sealed it tight, and left the hall.

After Rayhan left, the panther automatically healed in 30 seconds. He went to his sleeping spot and silently slept waiting for another worthy human to come.

7 hours later. He was sitting with his family members.

He scooped 50 ml of that water and gave it to his mom, "Mom, drink it. It will help you get younger."

He had previously told his parents about the fountain of youth. So they knew, what its function was. She drank it and after not seeing anything change, she was confused but after some explanation from Rayhan, she drank another. Her appearance slowly turned 10 years younger. After that, she drank another 9 glasses of that water and her appearance changed back to her early thirties. Seeing this was like a miracle. Everyone opened their mouth in amazement despite knowing the result beforehand.

"Dad, you should drink some" Rayhan said.

"No. No. I am fine." He was saying but Hanhan, the young mother, gave him a hateful stare. Thus, he ended up drinking 11 glasses.

"Annin, you drink now." He passed her the glass. Her appearance didn't change a bit but from now on her physical appearance would age 5 times slower.

"Fanfan, You can drink 2 or 3. It is up to you." He said.

Fanfan ended up drinking 3 glasses of it. Fanfan looked younger than Annin. It was quite strange. Nonetheless, Rayhan was happy about this.

He kept the remaining water in a vault.

That night he had a threesome with 2 girls. It was one of the best nights of his life.

If Rayhan was only planning to live for another 50 years, he would not mind getting wrinkly and old but he would probably live for another thousand years. So, it was natural for him to want to look young a bit longer.

The next day, he woke up and started learning "Demon killing fist" from his father. He had a feeling that if he trained hard for this next month he would be able to see good improvement in his combat strength. The fight against the panther had helped him in this aspect a bit.

Since Karin had said that the other beast was much stronger than the first one. He would not go in there without sufficient preparation. In his mind, he had already assumed the beast to have a power level of 350. He would not go before he reached the range of 350. Since he was stimulated by the pressure of the next guardian beast and due to the fighting experience with the cat he reached the power level of 320 after a month of intense training.

Another two years passed. His mother didn't seem to have too good of martial arts aptitude. But again she was in her sixties. It was not the ideal time for growth. She had just reached a power level of 100. She had started nagging about grandchildren. So, he agreed to her demands but he said that he would father a child when he ate paradise grass and it might take 2-3 years. Surprisingly, she didn't nag this time.

His father had taken the cue and encouraged his mother to train a bit more. Annin had reached 210 and Fanfan had reached 130. He urged Fanfan to train harder because he was going to impregnate her in a few years. Naturally, he wanted her to become stronger.

It was rather difficult to increase after crossing the threshold of 300. However, Rayhan had used the guardian beast as motivation and he had rigorously trained to reach a power level of 345.

His 'Demon killing fist' had come a long way but the pale ki had yet to be invisible.

He was waiting for the day when he reached 350. He had decided to go to the forest of light after that.
