I saw many where confused so breif version, MC will create Spirit Pagoda and Tower of Babel.

Spirit Pagoda will sell artificial soul rings, by creating artificial soul rings through formations. They will sell Elixirs, enchanted weapons...etc

In Original timeline either you become genies with an exceedingly fast cultivation speed can obtain the first Soul Spirit free of charge from the Spirit Pagoda.

Ordinary individuals can purchase a Soul Spirit for a fee proportional to the Soul Spirit's age.The price of a 10 years Soul Spiritis 70,000 coins and 100 years Soul Spiritcost 1 million coins. There are also random Soul Spiritthat cost 30,000 coins. You can try your luck in a lottery to get a 10-year Soul Spirit, or a 100 year Soul Spirit. There's a very high chance that the Soul Spirit gotten won't be suitable for the user's Spirit. It's also possible to obtain a defective Soul Spirit. The Price is too much, right.

Make a contract with a spirit beast with mutual agreement.

Do the Tower Attack. Which was basically a Dungeon, my plan is to change it to Tower of Babel from Dan Machi.

So ordinary people cannot buy artificial spirit rings at such huge prices, so we MC will create Tower of Babel (Danmachi), where People can got to fight monsters. These monster will drop spirit stones, which can be either used to boost Soul power or give to Spirit Pagoda to get Artificial soul rings, Elixirs and weapon..etc

Last is Soul Tattoos with Pokemon spirits, which similar to Twin Martial Spirits. But although they are powerful,there powers are limited and could evolve them.
