MTL - My Father in Law is Lu Bu - v2 Chapter 892 main idea?

Ukei Kaito fought a desperate struggle in order to fulfill his role as a summoned hero. He defeated the Demon Lord and saved the very world, only to meet an end filled but with betrayal. The companions that he’d trusted throughout his journey betrayed him and killed him by sticking a blade through his chest.

If he wanted to boss around, he could do whatever he wanted. I would continue to farm, but if he tried to attack me, then he would not live to see another day.

Zhao Hai was a shut-in until he was transmigrated to another world with a farm and taken over the body of a fallen noble. The land that the noble had was one that could not grow anything. He also had a fiance who was the heir to a principality. To make matters even worse, he was talentless in martial arts and magic where he couldn’t even learn both.

“So what if I can’t do magic? I have my farm. Let’s see you try and attack me! I’ll let my bugs out to devour all of your military rations! I’ll put pesticides in your water source and grow weeds on your land! Let’s see you try and attack me after that!”

“What? You’ll hire assassins to kill me? Try and do that when I’m hiding inside my farmhouse. Once that is over, I’ll rid your country of all your food sources! Your citizens will come after you instead of you coming after me!”

The shut-in had a slightly foul personality. This is a story of how he, and his farm, became a nightmare to the people of a world of swords and magic.

By accident, Lu Zhiyu found the entrance to a low-dimensional world, and thus began a totally different journey!

Free to control everything in the low-dimensional game, Lu Zhiyu felt like a gamemaster, and even God.

Chen Sha came to a world of immortal martial arts and was ordered to take charge of the world’s first sect.

Before his death, the previous chief told him:

“If you don’t become the best in the world for one day, you are not allowed to go down the mountain for one day.”

So he closed himself in painstakingly, crossed the heaven gate in his body, and faced off against the ancient and modern powerhouses…

…

Many years later, Chen Sha recalled the day he went down the mountain,

From the moment he descended the mountain, he was number one in the world.

In the next ten epochs, any gods and demons have returned, immortals and Buddhas have lived in the world, ancient powers and ancient gods have appeared one after another.

No matter how the times change, he has always been No. 1 in the world and has never changed.
