Rise of the Demon God

The old man simply looked at Long Chen weird, surprised at the change and confused about the reasoning behind. 

He stepped closer to Long Chen and looked deep into his pitch black eyes. 

"Fine. We shall begin the training again. Get ready. I'm putting you on battle training." 

He clapped his hand once, sending Long Chen to a different space where ten powerful monsters were surrounding him. All the monsters were slightly stronger than Long Chen. 

"Now that's what I missed... Powerful enemies." Long Chen cracked his knuckles. 

The beasts started running towards Long Chen to attack him. 

At the same time, Long Chen's figure flickered as he appeared above the beast and simply stabbed his bare hand inside the beast. 

Even though the beast had a defensive skin, his hand acted sharper than the sword and managed to pass through. He grabbed the spine of the beast and pulled it out, killing the beast more brutally. 

The beast roared in pain before falling to the ground. Long Chen tossed the bones of the beast away. 

"You're slow," he commented before appearing above the next beast. 

In just the next two minutes, Long Chen killed the beasts that were against him. 

Even the old man was surprised at the speed of Long Chen. 

'He looks to be stronger. But even more than that, he looked bloodthirsty. It's as if he just doesn't want to defeat the beasts, but he wants to kill them. It's as if killing them is a game for him which he enjoys.'

The old man was observing the actions of Long Chen from the start. In fact, he even gave this test especially to observe Long Chen. 

"Old man! Come on! Give me some strong opponents!" Long Chen called out, knowing the old man was watching him. 

The old man rubbed his chin before deciding something. 

This time, he sent ten human looking cultivators. Five of the cultivators were women, while three were men. And there were two who appeared to be teenagers.

He wanted to see if Long Chen was going to hesitate in killing the teenagers who were weaker than him in cultivation. However, that wasn't the case. 

Long Chen didn't hesitate even a little bit. He saw all those who stood against him as their enemies without caring about their age. 

He attacked everyone in the same old fashion with the intention of destroying them. 

"Come on! Stop sending such weak opponents! Send me stronger! And send thousands or millions! It's boring!" Long Chen exclaimed after finishing up all the opponents. 

'Sigh.' 

The old man sighed in disappointment as he watched Long Chen kill the cultivators without any consideration. Even though he knew that Long Chen had an idea about these enemies being fake, but that didn't matter. He knew that there was something inside Long Chen which had changed. 

He wondered if it was the same thing that caused his eyes to turn black. Or was it something that happened before that?

Despite that, he didn't just abandon Long Chen. So what if Long Chen was slightly more ruthless... He was still his student. He couldn't abandon Long Chen. 

He just needed to train Long Chen and guide him towards a lighter path. 

...

Through the next couple of centuries, the old man trained Long Chen like usual while also throwing some calming skills in the mix. 

However, nothing worked. Long Chen's eyes remained pitch black. They didn't return to normal. And he was still a ruthless person who enjoyed killing the enemies. 

It certainly made him a better warrior though. Long Chen was a powerful opponent for anyone, even if the person was way above his cultivation level. 

Moreover, to the old man's surprise, Long Chen's cultivation speed had also increased at this point. He didn't know that it was because Long Chen's bloodline had grown even more. 

Before long, the promised thousands of years were gone. 

The old man had finished all the cultivation resources that he had prepared for Long Chen. He had nothing left anymore. Moreover, he also taught Long Chen all the skills that he knew and even the ones he didn't know. 

The training was finally finished. 

Long Chen stood before the old man, looking more mature and slightly older. He looked like a person who was in his mid twenties. His long dark hair was tied to a ponytail. His eyes were still black for the most part, but somehow it suited the careless look on Long Chen's face. 

He was also wearing different clothes now. His clothes were all black, matching his eyes. 

"And with that, we are done. Your training is over. How do you feel?" The old man asked Long Chen. 

"I feel the same as I did before, just a bit stronger," Long Chen replied. 

"Hahaha, you little boy, you call that just a little bit stronger?" The old man asked. "You are more than a little stronger. And you're not the only one."

"Want to meet your family? See how they have grown in the last thousand years?" The old man asked. 

"Sure. Let me see your magic, old man." Long Chen smiled. He was slightly excited to see his family. How much had they grown? And who grows strongest amongst them? He had a feeling that it was going to be Ji Shan.

"Alright. First, let's start with the oldest. I honestly didn't expect him to grow so much at that age, but he was certainly talented."

The old man clapped his hands once, bringing out a portal under him. 

As the portal opened, a man flew out of it. 

"Grandpa Ren," Long Chen said, smiling.

He could see Long Ren flying above him. 

"You've broken through to Saint Realm. Now you're at the peak of the mortal world. Nice," he said. 

"Hahaha, yeah. I didn't know I could grow so much despite my lack of talent and at this age. Who knows, a good teacher can help someone so much." Long Ren said before bowing to the old men. 

Even though Long Chen's growth wasn't much for this level, but reaching the peak of a mortal world at that age was certainly good. Moreover, it also gave him a long lifespan to live many years. Long Chen was pleased.  

"Next." The old man clapped his hand. 

With a single clap, another portal opened up. And this time, a lady came out of the portal. 

"Mother," Long Chen commented. 

His mother had also reached the Saint Realm. This was somewhat disappointing for him.. He had expected his mother to grow more than his grandpa.
