So the second one is like this:
It's about a demon that got kicked out from his kingdom,and wants revenge. The bad thing is that the MC is crippled and can't cultivate or train his body to get any stronger than the body of a normal human.
Because of these reasons, the MC decides to go to a human kingdom, but there they don't accept demons becoming kings so he decides to become a great merchant.
The MC starts working on a farm, doing labor work and with the money he gets in one year, the MC actually starts buying ingredients for cooking. He can cook very well because ever since our protagonist started working on the fields, he secretly ate some of the plants and started researching on how to make them taste good. One can imagine how many types of food one eats in a whole year working on a farm that grows 7 different types of food each month(the time for crop growth there is faster)
After cooking the food there is an arc of the story on the battlefield where he chose to sell the food(soldiers are usually hungry after fighting, and after going to battle the soldiers there are usually paid a little of their wage) the money income is great and like that our merchant starts growing.

The MC takes a long time to get enough money and hire an army, getting his revenge right after.Problem is, now he offended the demons and has to fight against them.
The enemies are generally the demons and his competitors.
About world building: there are 2 continents, on MC's continent there are 5 big kingdoms and 15 small ones, he lives in one of the big ones, the Khalifa kingdom.
There are 4 rational and civilized races:humans, elves, demons and dwarves, although there are a lot of races like trolls, griffons, ogres, etc.
Cultivation is divided into the levels: Human, Material, Spiritual, Soul Ponderer(can feel one's soul), Soul Controler(can use soul energy), Purified,Saint, Divine and King.
One of the production type cultivation is to use talismans for various effects depending on the stone and the rune one uses on it.
The MC actually finds a way to fight later, and that is to use 5 special talismans that he finds and have characteristics of a dragon temporarily,with each of the talismans giving a new characteristic and more power. These talismans require a lot of energy to be used so he has to use expensive energy crystals.
The name of the story would be THE STRONGEST DEMON MERCHANT or THE RICHEST DEMON MERCHANT
