The shop owner did not reject Tang Zhen's request.
This was something that would benefit him, so he naturally had no reason to refuse. However, how he did it had nothing to do with Tang Zhen.
This was because what he was going to do next would require him to use the shop owner's resources and trump cards. There was no need to let Tang Zhen know.
After the results were out, he would inform Tang Zhen.
Tang Zhen would not ask too much. If he were to randomly interfere, he might end up making things worse.
Not every God King of the Sorcerer world had the intention to rebel, and even harbored hidden hostility towards the loucheng world.
If Tang Zhen personally came into contact with it, he might end up overreaching himself.
The situation would be completely different if the shop owner personally took action, and the success rate would also be multiplied.
