After he had finished looking around, Mo Yunhan finally arrived late with Ye Qi.

Ye Qi looked around but didn't see anyone.

"Old Luo, where's that amazing girl?"

Luo Jiu had just finished bowing and didn't want to say that Mo Yunhan had arrived too late, so he simply handed over the drafts respectfully.

"My lord, that girl didn't want to stay any longer and has already left. This painting is even more exquisite than I imagined. Take a look here..."

He leaned over and pointed at the drawings, explaining them with unusual excitement.

Mo Yunhan, however, smelled a very faint fragrance emanating from the blueprints.

"Jinshan".

"What?"

Luo Jiu didn't understand and looked puzzled.

Mo Yunhan snapped back to reality.

"fine."

"Make the product as soon as possible. Once it passes the drills and is confirmed to be error-free, it can be handed over to the Ministry of War's Manufacturing Department for mass production."

Luo Jiu nodded, then, as if remembering something, ran to a pile of items, pulled out a box, and handed it to Mo Yunhan.

"My lord, these are the crossbows and hidden arrows and boot arrows I modified. You may try them out to see their power."

Ye Qi happily moved closer.

"Old Luo, has our Dark Guard Battalion got something new again?"

Luo Jiu still felt a little regretful.

"If that young lady is willing to help, our Great Zhou's military reserves will surely become even stronger."

He looked out the window with a sorrowful expression.

Ye Qi stopped joking and patted his shoulder.

Luo Jiu's brother, nephew, and nineteen members of the Luo family were all generals in the military corps. They followed the army to conquer the Sui Dynasty, but were brutally crushed by the Sui Dynasty's military forces, and none of them survived.

When Luo Jiu heard the news, he was working on a mechanical box. He lost focus and destroyed one of his eyes. He then retired from the mountains and never came out again.

"Old Luo, the Sui Dynasty has been destroyed, and their souls will rest in peace."

Luo Jiu looked away, her eyes still a little red.

"I only hope that the Luo family's family learning can help the military and political affairs of the Great Zhou Dynasty, so that the soldiers and officers will suffer fewer casualties."

"My lord, you are the God of War of the Great Zhou, you will protect the Great Zhou, won't you?"

Looking into Luo Jiu's eager eyes, Mo Yunhan nodded solemnly.

"I will certainly do it."
