There weren't many people that Lin Jin respected a ton in this world, but Tianzun was definitely one of them. For one, Lin Jin had been worshiping Tianzun like an idol ever since reading about him. Also, Tianzun had a prominent reputation among the other immortals and was considered a distinguished senior.
Hence, Lin Jin respected him so, so much. As for other immortals who had committed wicked deeds, Lin Jin couldn't be bothered with them no matter how experienced they were.
Tianzun chuckled before scanning Lin Jin up and down and then nodding his head. "Hello, mere mortal, haha. I'm a mere mortal too. I may be much older but I surely can't compare to young folks like you."
As he spoke, he glanced at Xiao Huo with admiration in his eyes. Then, he looked at the immortals with their pet beasts and nodded too.
