Drink a cup of Ganges river water and be reborn as an Indian in the next life

Was it the heavenly tribulation? Had his modernized and fully automated heavenly tribulation finally come?

This was the first thought that came to Song Shuhang's mind.

Lately, he had constantly been thinking about about that modern heavenly tribulation of his that could befall at any time. Therefore, when he saw the cannon appear, he first thought about the heavenly tribulation.

However, he immediately returned to his senses and concluded that the cannon couldn't possibly be part of his heavenly tribulation. After all, which heavenly tribulation of the Fourth Stage would drill out of a space crack? If the heavenly tribulation from the Third to the Fourth Stage was this powerful, cultivators would have ceased to exist long ago.

Besides, his current strength was still far from reaching the point where the heavenly tribulation would commence.

So... who had brought this cannon here?
