I am Lin Fan and I’ve become a jack of all trades just because of a powerful Encyclopedia.
In the first ever competition organised for trolls, all the other contestants lost. The crowd exclaimed, “Brother, you’re so good at trolling.”
Lin Fan replied, “But I’ve never been trolling…”

A young orphaned boy named Mu Yi is saved by an old travelling Taoist Priest. They travel the world ‘scamming’ people by ‘exorcising ghosts’ and ‘slaying demons’, that is until the old Taoist Priest dies and Mu Yi is forced to realise that all is not as it seems. He was told stories of armies of ghosts, hordes of zombies, horrifying demons, and worst of all, the cultivators who controlled them.

Mu Yi takes his first steps towards rising to the top of this dark and cruel new world.

A man who was once called the world’s strongest agent ended up becoming a teacher after his retirement, to train a new generation of agents. After many years of training his disciples, he was killed at the age of 60 by a secret organization’s ruse and was reincarnated in another world with his memories intact. Though he was surprised by the existence of magic and the strange species in that world, he quickly adapted to his condition as a newborn and took advantage of it. He acquired special magic and gained a massive amount of strength thanks to his rigorous discipline, in order to reach his goal: Resume his career as a teacher which he left halfway through in his previous life. This is the story of a man, who, based on the memories and the experiences of his previous life, became a teacher who travels through the world with his students.

As soon as Lu Xuan woke up, he became an ordinary spiritual planter in Sanxiufang City, guarding a one-acre three-point spiritual field, and living in the world of practice.

Fortunately, I accidentally discovered that every time a spiritual plant matures, I can get extra rewards.

Harvest a sword grass and get a sword pill.

Harvest a Xuan Chong vine and get a share of Yin Xingsha.

Harvest a Youquan flower and get a piece of Zhiyan Pill Recipe.

…

From then on, he guarded his spiritual field peacefully, and sat and watched the world of practice turbulent and vicissitudes.

“What about fighting skills, exploring secret realms, seeking immortal fate, obtaining magic weapons…all have nothing to do with me!”

“I just want to farm quietly.”
