Please recommend a soul novel that traveled through another world. Thank you!

I'll first tell you the outline that I've memorized.
The protagonist's soul transmigrated due to an accident-Fusion with two other souls-Possession of a child's body-Opening a restaurant-Becoming a feudal lord-Making a spatial ring transmission array-Opening a forbidden paradise-Hiding from war and bringing his people into the forbidden paradise.
Because he accidentally passed through a child in another world, he fused with the soul of the child and another sword cultivator who failed to transcend the tribulation in the Immortal Sword World.
Because he had the memories of a Swordsman, he was also a Swordsman. At least he had started to be a Swordsman.
Later, he opened a restaurant. Alchemy was taboo in this world, so there was no soy sauce. The protagonist created soy sauce and distilled white wine, so the restaurant was very popular.
For some reason, he was given a title of nobility and a territory, and he gave the restaurant to a good friend to become a lord.
Because he had a flying sword, this guy used his spatial equipment to transport food from faraway places to the territory to sell. The super cheap subjects were very grateful to him.
That's right, there were no spatial equipment in that world, but the protagonist accidentally obtained a spatial box because it was the Swordsman Group Leader who made the spatial ring and teleportation array. They also made gunpowder and bombs
He spent money to use the space box to transport the people to develop a new territory in the forbidden area for him and use the mountain protection array in the Swordsman's memory to protect it.
Later, he led the people who were willing to follow him to the forbidden area to avoid the war.
Gods, help me think. Please, please.

I recommend " Killing the World in a Different World ". This is a fantasy novel about a different world. The main character, Gu Hongzi, is the remnant soul of a cultivator. He transmigrated to the body of a trash whose soul had burned out in the Utopia Continent and started a new journey. I hope you like my recommendation.
