Openly an Undercover Agent: He Gave Me Far Too Much

Lin Han was originally a disposable spy sent to the Great Abyss by the Tongxuan Kingdom. But after activating the Gift-Giving System, he decided to become an open spy, deliberately revealing his identity and using gifts and money to bind others to himself.

The protagonist joins the Demon Suppression Bureau, an institution with extraordinary status. Using his own methods, he learns cultivation techniques and wins over many people, gradually becoming a major force within the Bureau.

In the Great Abyss, he wins over numerous high-ranking officials and also makes secret deals with people from Tongxuan. Eventually, neither the Tongxuan Kingdom nor the Great Abyss Kingdom can do anything about him.

In the end, intentionally or otherwise, he helps the Great Abyss defeat Tongxuan, then uses the power he has built to defeat the Great Abyss and found his own kingdom.
