Grandpa Ji glared at him and said, "You don't trust me? Why would I lie to you?"

"Sure." Ji Shiting nodded. "However, since you're willing to bring this sample for a test, you have to admit that this hair is indeed Little Zheng's. If the results don't meet your expectations, don't say that Shengge got it wrong."
"Don't worry, Grandpa. It's really Little Zheng's hair." Ye Shengge looked at Grandpa Ji solemnly.
Grandpa Ji sighed and nodded. "Okay. If the test results show that Little Zheng isn't your son, I won't bother about it anymore. Is that okay?"
