Jiang Xinyu transmigrates into the 1950s without parents. In a time of famine with nothing to eat?But she just wants to live the life of a happy-go-lucky slacker...So she has to roll up her sleeves and fight!Carrying space, full of blessings!Heaven's favor, what you think is what you get.While others starve, she gains weight, determined to live out the luck she didn't have in her previous life.

For the sake of his family, Ren embarked on the popular VRMMORPG, COVENANT, that used real-time in-game currency. But being a mediocre player who only knows how to gather information, he was put in a supporting role.

As the game explodes in popularity and every multibillion-dollar company invested in the game, things have turned for the worse for Ren. Due to the amount of information he gathered, the cheats, secrets, quests, and bugs he discovered, he was silent in fear of selling the information to the other guilds.

But given a second chance, he went back in time when his father was still alive and COVENANT was just in its starting phase.

This time . . . he wouldn’t be that guy on the side who gathered information from day in and day out for ten years.

Equipped with the games knowledge he accumulated, he will become . . . an Alchemist!

Chrono Mage? Djin Master? Summoner? Necromancer?
Chaos Lord?

What good are those?

Sure they’re powerful and rare classes and sought after by guilds, but it’s the alchemist who forged artifacts and concocts rare items and potions that gets the most coins at the end of the day!

It was better than being a blacksmith or a crafter! Plus, he could use all sorts of magic without limit to race and class!

It was the ultimate class! And no one even knows it!

When he woke up, Ji Que traveled to a dangerous world where fairy mountains collapsed and temples were abandoned.

Fortunately, he has a supernatural ability, which allows him to save his understanding and use it like banknotes.

The more understanding you accumulate, the more miraculous you can realize.

Comprehend “swimming”, you can swim as fast as a fish in the water, and you can swim up and fly on the ground.

After comprehending “The Analects of Confucius”, the knowledge will be integrated, and the muscle strength will increase exponentially.

After comprehending “The Book of Benevolence”, I have learned one more combat technique of “dividing people into two”!

After comprehending “Yi Xue”, I accidentally mastered a skill of “smashing the head into the body cavity”!

Comprehend “Xiaoyaoyou”, “Mozi”, “Taoist Tibetan”…

Afterwards, Ji Que started holding back his big move, wanting to see what effect it would have if his comprehension reached its limit.

Until one day, he couldn’t bear it any longer, and he kept wishing for a certain stir-fried dish that he had always wanted, so he used all his understanding on “stir-frying and tossing spoons”.

Later, there were rumors in the rivers and lakes that not long after a terrifying plague god came to the world, he was thrown to death by a passing cook…
