That's right, the old man who tailed Shen Tang was only in the seventh-grade.
Shen Tang had even personally asked Zhang Zaiyue before.
Why did he take in such a low-grade martial artist as his follower?
At that time, Shen Tang had even mocked Zhang Zaiyue.
He took in anyone.
Now he understood that he ought to be the one being mocked.
The old man's ability to conceal himself was too impressive.
So impressive that even he, a fourth-grade martial artist, could not detect it.
Zhang Zaiyue was lucky to have the old man as his follower.
"Huff… Huff…"
Shen Tang panted and looked up at the old man in Su Jingxing's arms with difficulty. He questioned through gritted teeth, "Zhang Zaiyue told you to follow me, what are you monitoring?"
The old man kicked his feet and grabbed Su Jingxing's arm with both hands. He kept struggling, but it was useless.
Shen Tang's question was ignored.
