One must make a simple oath: Never Lose.

By definition of 'Lose' it mainly meant that one shall never die during he process of a battle however if you pass out, one shall receive a minor punishment.

Your cultivation level would be on hold temporarily.

Meaning to 'win' was to kill the opponent without mercy

You were guaranteed to have an easy time cultivating for the first few realms however the only way to advance to a higher realm was pure fighting skill.

If at anytime you have lost a battle, you're cultivation will completely shatter and will die a painful death via separation of tendons; all 5 orifices bleeding; trauma to the nerves; pores ripping; bones turning inside out and the genital being mutilated.

Your soul will be roasted over a flame that will never end until the very essence of yourself will cease to exist in so called 'Glory'.

Each breakthrough will follow with pain and temporary weakness.

The one good thing about this was that it was unable to be cultivated with Qi or Mana meaning it was useful for those with poor talent.

He remembered the days so vividly when he asked his father why this wasn't available to the public.

As long as they gave it to a strong willed commoner, would they instantly have a strong warrior.

What's more, given that the warriors would grow in a controlled environment with the resources they have at hand, they could essentially create a powerful soldier.

At the time, his father laughed out loud for a long time until he gave a cold glare.

"Let me tell you of a story where we got this manual from.."

"Once there was a young man who grew up in a rural village, during a special night, he found a cultivation manual in the deep woods. Thinking he had won life, he was ready to show it off to his family and friends but instead kept it for himself."

"One day challengers appeared one after another and just like magic, he won. Years soon passed and he became the strongest person within the village and made sure to be filial child by doing the crops."

"Soon a messenger from the kingdom came 'Our king would like to see you'. He met the king and was recruited to become a soldier. However disaster struck as their capital was soon filled with famines, plagues, natural disasters and wars"

"A line soon carved in blood at the end of the book wrote 'Fate is not meant to be played with'."

The child was without patriotism and was filled with ignorance about the outside world.

Although that was a point that could've been brought up, the story suggested that if he hired a person to fight and purposely won, his life would be gone.

Ultimately, his goal was to become 'Undefeatable'

Although very unlikely, Christian would wander around the world and hope that luck would be on his side.

Compared to being a sitting duck, he would rather still choose this choice even with such a heavy price.

He did not necessarily have to fight anyone but he wanted to test out whether enlightenment about 'fighting' itself would present any improvements.

Dean was starting to get worried at the fact that Christian was muttering and in deep thought for a long while now.

It was abnormally long for a simpleanalysis of who this person was

He was starting to be afraid that Christian found out about his lie even though he made sure to try and be as vague as possible yet also blunt with facts.

Another was that he would skimp out on his part of the information.

Rose had just arrived and placed a tray with two teacups and a kettle.

She first poured out the tea for the two of them before taking back the tray and entering into the kitchen once more to make some medications for Christian.

Dean realized that this sudden invasion with a kettle of tea made him get into a very dangerous situation.

He definitely saw Rose enter a herbal store meaning that she could've simply placed some paralyzing herbs into the tea and made him unable to fight.

Leonard was able to show him how deadly poison can be just by processing it a little or turning it into a pill.

Cautious he looked back to Christian but saw that his mind was blank.

'I wasn't cautious enough!'

Christian could have given a signal to Rose that suggested to put poison into the tea.

Sweat began dripping down his clothes as he tried to ignore the tea and force Christian into a position of answering

"Who killed Leonard!?"

"Huh, oh."

There was a slight surprise in his voice as he tried coughing to clear his mouth and proceeded to drink a cup of tea.

Dean was concerned what he was doing but in the end face palmed.

It was very unlikely that he would take medicine before meeting as it would be unusual for him to do that.

Soon he also took a drink but it was less bitter than he thought

"You have more important information so I'll tell you a different one instead."

He frowned at that news but was interested in things he spurted during his fight.

"In this world, there are more dangers than you can expect. Artifacts capable of destroying countries, Conjurers able to take apart time and space, gods watching over mortals, etc. Higher, Lower, Middle and Lost Worlds"

"Xuan Beasts terrorize the Lower Worlds and create breeding grounds to create little monsters. Middle Worlds just like this one, allow a single race to live on and eventually evolve with enough help or devolve with raids."

Dean was ready to tell Christian to stop with his nonsense but his hand was telling him to just listen.

"Higher worlds where geniuses gather where different races are able to reach peace or utter war with each other. Organization built to destroy or create order within these worlds while Lost Worlds... are just forsaken lands."
