Bao Lian wasn't planning on killing Han Sen in front of the Very High, but he wanted to use this opportunity to teach him a lesson. There was nothing the Very High could say against that.
But Bao Lian was aware that Han Sen had the Shield of the Medusa's Gaze. Even Meng Lie had been frozen by Han Sen and left to dangle in the sky. The Extreme King had spent a great many resources resuscitating Meng Lie after that gross defeat. In addition, Bao Lian was just a primitive deified. He wouldn't dare try to take on the Shield of the Medusa's Gaze if it was used against him.
"We have brought Han Sen to the god area for practice. I hope you can teach him a thing or two, sir," Li Keer said.
"If you are both asking this of me, then I would be remiss not to help out. But if we use weapons, someone might get hurt. I suggest we don't make use of treasures. What do you both think of that?" Bao Lian said with a smile.
