Cao Jiao also sighed helplessly: "Yeah, I can only barely recite it. As for whether it is right or wrong, it is really hard to judge."

The reason why Jin Linlin wanted to prepare for a rainy day was because she knew very well that her husband, as a military general, would have to go to the battlefield sooner or later.

In this dynasty without "The Art of War", if he could write it out by heart, he and Xia Heng would take a good look at it. With his intelligence and talent, Xia Heng, as a counselor, would also have an important life-saving skill no matter where he was.

Cao Jiao naturally understood the thoughts of this eldest daughter, so she racked her brains and memorized "The Art of War".

With the concerted efforts of the two sisters, "The Art of War" was finally completed with some difficulty.

Both of them memorized the Thirty-Six Stratagems. These two books, which were like rare treasures to soldiers, were now presented before their eyes.

The two shook their sore arms, picked up a cherry from the fruit plate, put it in each other's mouth, then smiled at each other, and the smile was like a blooming spring flower.

Jiang Zhixu walked in and saw how close they were. He couldn't help but feel a strange feeling in his heart, as if he had come at the wrong time. No wonder his third brother was jealous.

"I need to go on a business trip these few days and will probably be back in three days."

"Well, take care of yourself when you are out there." Jin Linlin walked up to him and gently straightened the crooked jade pendant for him.

At this moment, Jiang Zhixu suddenly remembered the situation in the court, and his expression became serious, like a calm mountain. "The situation is tense now. You must be careful at home and don't go out easily."

Jin Linlin and Cao Jiao looked at each other and nodded. Just as they were about to hand the two books to Jiang Zhixu, they found that he had disappeared.
