MTL - Start with Psychologist - Chapter 781

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

He died in an accident and was reincarnated into another world. The Gundam works he had read before his death and the techniques in various military novels could be brought to another world.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?

Upon awakening, Lu Xuan found himself as an ordinary spirit plant cultivator, tending to an acre of land merely scraping by in the realm of cultivation.

Fortunately, he stumbled upon an unexpected revelation: with each maturing spiritual plant, he received additional rewards.

Harvesting a The Firefly Grass yielded a Golden Sword Technique.

From the Blood-Devouring Vine, he obtained a Purification Talisman.

And the Phantom Spring Flower gifted him a prescription for the elusive Luminous Flame Pill.

Henceforth, he contentedly tended to his own spiritual fields, observing the tumultuous tides and shifts in the world of cultivation.

“Duels and clashes, expeditions into secret realms, immortal fortunes, obtaining mystical treasures… None of it concerns me!”

“I simply wish for peace and quiet to tend to my fields.”

Chen Shen traveled to a world of immortals and became the corpse collector of the Xianzong, burying the dead disciples every day.

To bury the disciples of the seventh level of Qi training, to obtain their immortal skills and experience, and to obtain part of their spiritual roots.

To bury the disciples of Daofeng’s inner disciples in the array, get the spirit-gathering array, the killing array, and the experience of the array.

Bury alchemy masters, get Peiyuan alchemy recipes, build foundation alchemy recipes, and get alchemy master experience packs.

Bury super geniuses, complete spiritual roots, and achieve heavenly spiritual roots…

Twenty years later, Chen Shen, the body collector who has grown into a Jindan Zhenjun but is still low-key, discovered that the corpses sent this time were unusual, as if they were from the whole sect!
