What does TVB's dramatic ending mean?

The protagonist's ending: In order to get rid of the devil and turn it into a crystal, Shi Gandang relies on Ma Ji's help and uses all his spiritual strength to die with the devil. Ma Ji finally got into a taxi and drove away the demon, but he didn't stay with Zhire because of the devil's last curse. Zhiruo is ready to accept Ma Ji, but their relationship has also declined because of Ma Ji's alienation. Beer has become a ghost but has remained in the world. In fact, he didn't want to leave Ma Ji.

In the end, although Ma Ji shouted Shi Gandang loudly, the ghost of Xiaohao finally appeared, in fact, in order to satisfy Ma Ji's initial heart ~

I hope there will be a second film, because Ma Ji's natural magic has not been explained clearly, and the last pregnant police sister should also be possessed, maybe it will be a new demon ~
