The Zheng iron smelting workshop he supervised became the greatest guarantee for the Zheng family in the subsequent hundreds of years of war.

It is said that Huaiwen, a famous forging master in the Northern Qi Dynasty, also used the technology of Zheng's iron smelting workshop when forging the famous Su Iron Sword.

Thinking of this, the purpose of King Yang Liang of Han sent Zheng Chang back was clearly visible.

"Little scholar, why don't you talk? What are you thinking?"

Yan Qing didn't speak for a long time, Duoduo couldn't help but feel a little surprised, so he pushed him.

"Duoduo, we're going to have trouble!"

"What trouble?"

"I always feel that the second master is afraid he has bad intentions when he comes back this time... If he causes trouble, we may be in danger."

Duoduo's face changed, but it quickly returned to normal.

"Since that's the case, just tell the master and ask him to be more careful."

"If you make a mistake in the Lord without real evidence, you will be beaten to death by sticks if you do it." Yan Qing shook his head, "It's better to be cautious."

Duoduo said: "Then what's your idea?"

"this……"

Yan Qing hugged his legs, pondered for a moment, and then whispered: "The most urgent thing is to get evidence. Only with evidence can you remind the master."

"evidence?"

Duoduo looked embarrassed, "Where can you find evidence? The second master stayed in the inner house all day, so it's hard to find it."

"It's hard to find the second master. Maybe the smiley tiger can find clues?"

Yan Qing thought about it, his eyes turned, and he had a plan.

"Duoduo, do you dare to take risks?"
