A crisis

Xiao Yuanshi thought deeply for a moment.

He instructed his trusted aide, "Continue to send people to keep an eye on Zheng'er. It's best to create an opportunity to destroy his reputation."

He acted as if he was thinking of his son. "The capital is too complicated with bloodshed and the glint and flash of cold steel. It's not suitable for a village boy like him. He should just stay in Nanxi county and be a rich man."

Since he had opened a few workshops, he should manage them well and better not take the imperial examinations.

He couldn't manipulate him. Yet, he might even backstab him. 

He had to be ruthless and cut off his son's path to success.

His trusted aide nodded. "Understood. You are also thinking for your eldest young master's sake, Sir."

Xiao Yuanshi thought for a moment and emphasised, "Don't leave any evidence behind. Do things cleanly. Don't let Zheng'er know about it and discover anything."
