Later, He Became A Royal Healer - Chapter 130 - He means what he says.

The Empire's forces retreated in desperation—trampled by faceless horrors bringing darkness and death to these once beautiful lands.Only the most courageous stood in defiance, forming a last defence to buy the people time to flee—fighting until the final embers of hope burned out.A man stands with a silver sword, like a beacon of hope to those around him. He roared with all his might drawing his blade against the overwhelming enemy!“You face Lancelot, Sword of the Empire! ”These horrors tested the Lord's grit and loyalty in the final moments.“Should my blade break, I will use my body!”The knights had fallen, broken swords for their tombstones, and lords fled, betraying the Empire to survive.“If my body breaks, I'll use my Soul!”Lancelot, the sword of the Empire, fought alone.All hope seemed lost.“And if my Soul fails...”What could a single man and his army do?He fights against the dark tide, blade in hand, heart on sleeve.“I will sell myself to the devil for revenge!”But he was too weak, too fragile.The last Lord of humanity stood against the enemy.Lancelot was a master of the sword, a mortal, neither a God nor a Saint.Miracles were beyond his reach.Now only a broken man impaled on his own destroyed throne.His blade shattered—now, like rose petals, it was scattered across the charred ground.Lancelot's soul was fated for the abyss as the light faded from his eyes.His last ounce of resistance used staring at the man who betrayed the Empire.Now with only the desire to kill, crush and seek revenge smouldering inside him.Now unwilling to die and desperate to fight once again.He desired to fight for the people who supported him.Lancelot refused to surrender, to fall like this.As quietly in the abyss, a voice whispered to him.It tried to entice the Lord, ignite his desire to win and fight again.“If given a second chance, to relive your life with a different choice... Would you Accept?”Blood gathered in his throat, forcing him to reply in his mind.A frail and broken voice'There is no reason to ask, of course!'“No matter the cost?”'Even if I were to lose everything...''If my people can live on. I would sacrifice everything I have!'“You will no longer be the same, a monster, twisted and vicious.”“Will you still accept?”The Lord's heart ached, taking great pride in his humanity.To lose that caused his mind to falter.Finally, out of power, unable to speak or reply with a trembling arm.Lancelot reached out.Towards the raspy voice.Towards the abyss.Towards a new future.[So you would accept after all...]'I must accept.''I must stand tall.''I must not break.''Because...''I am the Lord of humanity![Nay, you are the king of demons]

What are you going to do when you pass through another world?

Yalin(MC): Perhaps, many of those seniors who passed through another world would like to use violence to solve their problems, but I like to control the fate of a country with economics and races with faith, I use benefits to instigate others so that I profit, and even making them take risk for me without them even knowing. In each country the highest is the king and behind the king is a string that is attach to my hand, for I am their puppeteer.

Yalin(MC): Certainly the credit does not only belong to me, I must give my thanks to the great knights and their leader Zero(Code Geass). The supreme master of blood, the moon princess(Tsukihime), the black and white princess, and also my ‘good friend’ called by his title the ‘God’s left eye’, president of the neutral autonomous city. Finally I must give thanks to my loyal and competent subordinates!

This is the right version of the story on my account the other one had some problems on webnovel.A story about traveling through a system! Incest, multiple blood relatives, harem, pony cart, and light training. The protagonist's soul traveled through time and space to a newborn baby, and he was sent to Xia City when he was just born. At first, he didn't know that he was Liu Ruyan's son! The most important thing is that he was bound to a very bad system called the money exchange system, so after he could speak, he showed a melancholy temperament! Others thought he was sad about something, but every time someone asked him, he shook his head lightly and said no! But only he knew the pain in his heart! He guarded a system, but the system asked for money. It gave money for intelligence, but I still gave money for strength! Unfortunately, Liu Xuan, who was thrown into the welfare home, lacked money! Otherwise, he wouldn't have been hungry every day and bullied. Until Liu Ruyan came and handed over a 10 billion black card, the world finally changed. The beautiful mother's soft breasts that made people linger, and the long black legs that were longer than his life, yes, that housekeeper, the loose maid clothes, weren't they just waiting for him to fuck them? At this moment, Liu Xuan, who had been single from the previous life to this life, immediately notified the dog system after receiving the black card handed over by the beautiful mother, and directly blessed his bird gun that was growing well into a thick cannon...

“Welcome to Perfect Life Simulator!”

“You can choose to simulate your own life or someone else’s life to find solutions to many life problems!”

…

A watch handed down from his deceased parents allowed Su Wu to start a future life simulator.

He thought that he could really use this simulator to lead a perfect life without regrets, but unexpectedly things developed in another direction.

In the future, as long as there is light, there will be evil spirits that kill people;

Hanging in the sky and covering a city, it leaves a city without red lanterns of living people;

The scarlet eye that can use a mobile phone to spy on the specific location of others…

Will such a future really come?

…

“you are dead.”

“This simulation is over.”
