After reviewing three memorials, Huang Banban reminded him that the blacksmith arranged by the Ministry of Works had arrived.

Xuanren entered the warm room.

The three blacksmiths were all elderly and well-informed, but they had never imagined they would one day be summoned by the Emperor. The status of a craftsman was only slightly higher than that of a merchant.

As soon as the three men saw His Majesty, they knelt and kowtowed, chanting, "Long live the Emperor! Long live the Emperor!"

"Get up!"

Zhao Huan handed the blueprint to the craftsman. Could he understand what it was?

Three or five minutes later, a craftsman who was frowning in thought seemed to have understood something and said excitedly, "Your Majesty, I understand one thing."

"Which one?"

"This one is truly exquisitely designed."

Zhao Huan looked at the craftsman holding the blueprint of the handmade honeycomb coal machine and saying something about how exquisite it was. The corners of his mouth twitched a little. He must have gone off track.

"This is definitely a weapon that can be used for both offense and defense. This shield has nine protruding spikes on it, allowing it to be used for both offense and defense. It also has the ability to camouflage. When you think it's a blunt weapon, just push hard and the spikes will pop out, capable of piercing a person's body."

Zhao Huan was stunned when he heard this. He knew you had gone astray, but he didn't expect you to be trying to catch fish in a tree.

In addition to proving Song Zhaohuan's amazing drawing skills, this incident also shows that it would be useless for Song Zhaohuan to just stay in the office and not go to the scene, and he had to be there and see the objects.

Zhao Huan did not explain and simply took the three craftsmen to the imperial garden.

The two guards were still making honeycomb coal seriously. They had already made about 70% to 80% of it, with only a small part left. The honeycomb coal was piled up in the sun.

"Stop for a moment, you two, teach these three blacksmiths how to make honeycomb briquettes."

Half an hour later, Zhao Huan asked the blacksmith, "Do you know what this blueprint is now?"

The blacksmith was so embarrassed that he wanted to hide himself in the coal pile. He lowered his head and said, "I know. It's used to make honeycomb coal."

"Can you do it?"

"Yes, with the blueprints, we can make it tomorrow."

"It's all about honeycomb briquettes. A stove, a briquettes holder, and a kettle. Do you understand now?"

"I understand. I understand."

The blacksmith who was trying to catch fish in a tree concluded again, saying that this design was truly exquisite.

Zhao Huan was very upset.

"Go down and bring it up when it's ready."
