In the central layer of the forest.
Theo's was closing the cave, as today he plan to go to his shed to get his stuff like clothes and utensil, as well as gather some food and water.
For 1 week he didn't went out of the cave in fear of some other cultivator or beast might attack him or discover this place and find the all knowing fruit, he doesn't want to take the risk. so he stay for 1 week only eating the black panther meat and that only last for 2 days. as his body tempered went further his stomach ask for more food. So he was hungry as well as thirsty. he didn't drank for 1 week, only get to lick the water drop inside the cave wall.
His body became so thin and he can't no longer wait anymore, so he plan to get necessary item and went out for search of food. He still didn't plan on going to the town, for might trouble come.
As Theo was closing the cave, when his six sense alert him for danger, so without thinking about anything he dodge to the left. When he dodge he saw the beast. It was golden fur monkey, and it was the same beast who didn't went away with other beast that day.
When he saw the beast Theo didn't think of anything and kick it. He kick it lightly but the force in it was huge, so huge that the monkey slam in tree and the tree broke. Theo was surprised with this new found power. He never got the chance to check his strength, the day he massacre the hunter was the matter of life and death and didn't twice to check his strength. Even he thought of checking his strength, they were too weak. And as for Gunther, in his mind never in once he thought that, because for him, his life matters most, so he plan out, how to kill Gunther.
But now, when he found out, he regretted not facing Gunther 1v1, who might knows, he can kill without that much. Even if he can't win him in Qi but physical, now he was sure he can kill him.
Thats how confident he was, now instead of running or planning to kill the Golden fur monkey. He thought of practicing and testing out his strength. So he put the sword back into the sheath throw it in the ground, as for not disturbing his movement while fighting.
Theo readied himself in a basic combat position that almost all people use while fighting, i.e. street fighting style. Theo never learn any fighting techniques except for sword technique and his sword technique won't come in handy while fist fighting.
The Golden fur monkey got up and the two start brawling. At first Theo was at losing position, he was getting beaten up monkey, but slowly and surely Theo was able to comprehend the fighting style and was imitating it against the Golden fur monkey. His fighting style was getting better little by little with each brawl, the two was having.
The Golden fur monkey was only able to notice it when both as neck to neck in equal. At this time we can assume that he was regretting his decision of not finishing it early. But what can he do, it was not his mistake, Theo was monster own his own. A monster who can learn very fast and as well as his body was strong, too strong as if he have infinite amount of stamina, with each breath his stamina recovers.
Theo too notices that, he was able to recover his stamina too fast, but still there was mental power drainage, that he can't solve easily. How much stamina does he have, does not matter in a fight, mental strength determines, and how much mental strength a person has does not matter, stamina determines. Both are polar opposite but in a battle this two factors decide how long a person can fight.
As the fight drags on, Theo was having problem concentrating, because of mental strength. He used all his mental power, learning the fighting style and using it on the battle at same time. He losing the battle, so he decided to end the battle. he hit the beast in the abdomen with the knee and punching it in the facing, making it roll in the ground unconscious. He smile at beast and went to pick up the sword to finish it once for all.
Theo was smiling cause he got to know his strength as well as got a good fighting style from the beast. Theo learn about the beast from the book he brought with the herb book, from the library. Because he have to hunt as well as gather herb, so he needs to extra careful that's why he bought that too.
Theo didn't fight with the beast because he have to gauge his strength, he fought it because he learn from the book that. The Golden fur monkey is one the beast, who said to have heaven equals strength, when they reach immortal stage. And Its one of the rare beast, whose fighting style can be learn by human beings. Humans and Beasts have different cultivation and fighting style, humans can imitate the fighting style of beast and can create it on that basis but can't learn the fighting style of the beast. But Golden fur monkey are different, there cultivation are different but there fighting style are similar to human.
As well as Golden fur monkey are very dangerous when they become intellectual beings.
