The reason why Ji Yen let the mortal hunter die is because he doesn't want them to spread the news of five petal tree. One Li clan is enough. He does not want another Li clan searching for the tree. It will be too troublesome.
And they were not some good people. Ji Yen could see from their aura that their hands are tainted with bloods. Not just animals blood but also with human bloods.
And he killed the masked man to take out some pawn, incase he needs to take down the whole clan.
After killing one of them, Ji Yen still did not showed himself.
The two remaining men gathered near and stood back to back, looking around solemnly.
The two men did not even look at the dead man clearly. If they did, they would have notice the blade that killed the man was just a feather.
The remaining masked man thought someone was following them. So that was why he shouted earlier.
He is right, except the one following them was not a human, but a bird.
Ji Yen stayed hidden on a branch, waiting for the right time to kill the other cultivator.
The two men kept circling around and looking.
When the masked man's back was at Ji Yen direction. Ji Yen shot out a much faster feather blade.
Shoosh....
The blade flew very fast. Then it passed by the hunter, aiming for the masked man.
This time the man was prepared. As soon as he felt a subtle danger from his back direction, he rolled on the side quickly.
Even though he was fast, the blade still pierced his shoulder. Then it pinned him to the ground.
The man could not move. He tried taking the blade out. But all those small feather threads stuck inside his body, making him unable to pull out the blade.
Taking the advantage, another blade came flying out the tree line. This time, the blade struck the man's throat and split it open.
Glu..glu....
Blood came pouring out of the man's throat, making him unable to breath.
Slowly and painfully, he died.
Seeing that, Ji Yen turned his attention to the last hunter.
To his surprise, the man was not there anymore.
So, Ji Yen spread out his sense.
Surprisingly, he found the man was running towards his territory.
"Good, that will save me some time." Ji Yen murmured.
Then he flew up in the air and reverted back his normal size.
Boom....
The sound of something hitting the air spread in the surrounding.
It was Ji Yen flapping his wings so fast and flying towards the hunter.
As the last hunter was running, he heard the sound of air splitting.
And when he turned around to look, he saw a large bird flying in his direction at a very fast speed.
Seeing that, he turned and ran as fast as he could.
As he ran, he kept looking back at the bird. And he could see the distance between them getting smaller and smaller.
The man desperately tried to outrun. But luck was not on his side.
Very quickly Ji Yen caught up to him.
When Ji Yen was just above the man's head, Ji Yen dropped down his whole body heavily.
His feet landed right on the man's shoulders.
Thump...
The man hit the ground with his front side and Ji Yen stood on his body.
He turned his face to his shoulder and looked up at Ji Yen's large body.
Swishh....
Ji Yen's wing blade cut his throat.
The man died with a horrified look on his face.
His last thought was, 'How did I not see such a large bird at the jungle...?'
Those were his last thought.
And how did Ji Yen manage to do it?
He simply changed his forms so fast that even the twocmasked men cultivators could not see him. And Ji Yen simply just shot his feather blade during that instant. Hence, Ji Yen was just too fast for them to react.
After killing those humans, Ji Yen did not touch the mortals.
But the cultivators, Ji Yen simply absorbed their energies. And when he finished absorbing the energies, their body simply turned into dust. Spreading in the air.
And he only got like 15 energy points from them.
For the mortals, Ji Yen simply left them at their own place.
Anyway, some wild beast will eat them and scatter their remains. Or whatever.
Ji Yen did not feel any burden for killing those lives. They were some bad people. And in his past life, those were his duty to kill. Now he is in this world, where dog eat dog world.
With all those exercises, Ji Yen was done for the day.
So he left the place and head back to his cave. And like usual, Ji Wen was inside cultivating.
Seeing Ji Yen coming, he asked. "Anything?"
He was asking about the discovery of the human traces.
Ji Yen simply said. "Some human cultivators appeared, but I killed them. So no need to worry for now."
"But we will have to face some trouble in the near future." He added.
Ji Wen simply nodded.
As Ji Yen sat down, he remembered something and said to Ji Wen. "It seems like a hail storm is coming, in 2 to 3 days. So we you better collect some foods for yourself. And after the storm, winter will be arriving soon."
Hearing that Ji Wen nodded and asked to Ji Yen. "How about you?"
"What about me?" Ji Yen looked at him, confused.
"I mean what about your food. Don't you need to eat?" Ji Wen said. Then he added. "Well I will also collect some for you too."
"No need. I still have many energy left in my body." Ji Yen simply waved it off.
Puzzled, Ji Wen looked at Ji Yen.
"Ohh I mean I can store excess energy in my body. So, I don't need to eat for days. Don't worry it's one of my abilities." Ji Yen clarified.
