The whole family is obsessed with love? The princess woke them up one after another.

"You, you..." After figuring everything out, the Crown Prince completely lost his composure.

He reached out and pointed at Qi Zhiyu, his whole body trembling so much that he couldn't utter a complete sentence.

Qi Zhiyu smiled slightly and kindly poured the Crown Prince a cup of tea: "Take a sip and calm down."

The prince grabbed the teacup and drank it all in one gulp.

He closed his eyes and took several deep breaths to calm himself down a little.

"The martial arts skills that the princess displayed were a trap for Prince Ning." The Crown Prince stared intently at Qi Zhiyu and stated his thoughts.

"You know Prince Ning's temperament; he certainly won't let the soldiers train exactly as you wrote."

"The technique you gave me, in the eyes of ordinary people, completely eliminates the need for those previous steps."

Qi Zhiyu looked at the Crown Prince with a smile, her eyes full of encouragement, urging him to continue.

Her attitude made the Crown Prince feel extremely uncomfortable.

Qi Zhiyu is old enough to be his daughter.

Now, standing in front of Qi Zhiyu, he felt as if he were facing a senior.

"The prescription you presented today will not be used by Prince Ning immediately. Unless something happens to those martial arts soldiers." As he said this, the Crown Prince's eyes were filled with the pain of helplessness.

"If I'm not mistaken, within three days, the soldiers who practice martial arts will run into problems and will need the medicine you gave them to treat their illnesses."

Qi Zhiyu smiled slightly and held up two fingers.

The prince understood. Two days, only two days.

Even if Prince Ning hadn't invited everyone to the army today to see how well the soldiers were improving their martial arts skills, problems would still arise for the soldiers practicing martial arts two days later.

Prince Ning had no choice but to seek help from Qi Zhiyu.

The process may be slightly different, but the result is the same.

"Are the soldiers really alright after taking the medicine you prescribed?" the prince pressed.

Those are all people from northern Yunnan, and he doesn't want anything to happen to them.

Qi Zhiyu laughed: "I wouldn't ruin my own reputation."

The Crown Prince had just breathed a sigh of relief when he heard Qi Zhiyu continue, "However..."

"But what?" The prince's heart jumped again.

"However, they will never be able to cultivate the second level of martial arts," Qi Zhiyu said. "Don't worry, their lives will not be in danger."

"So, that's why the princess doesn't teach the soldiers of Da Rui." The crown prince was extremely certain.

"Using such a prescription would consume too much money."

Putting aside the question of whether it's worth spending that much money to build a group of highly skilled warriors, the amount of medicine in that prescription is truly painful to bear.

Too expensive! Too expensive!

"Princess, have you already considered the soldiers of my Northern Yunnan as your subordinates of the Great Rui?" the Crown Prince questioned coldly.

Qi Zhiyu went to such lengths to train that group of people, and in the end, she would definitely recruit them for her own use.

The feeling of spending your own money to please others is just too frustrating!

Unfortunately, apart from him, his father and the others were completely unaware of the truth.

Qi Zhiyu applauded the Crown Prince: "The Crown Prince is indeed clever."

The Crown Prince, his face cold, stared at Qi Zhiyu: "Is Northern Yunnan already in the princess's grasp?"

Qi Zhiyu smiled and said, "I came to Northern Yunnan to take it back."

"Doesn't the Crown Prince already know?"

The crown prince gritted his teeth, "Let the wolf into the house!"

"Actually, Your Highness, you're quite naive sometimes," Qi Zhiyu said with a smile. "I've already told you the plan clearly, yet you still dream of turning things around."

"Actually, you only have one path to take now, don't you?"

"You know what kind of road it is, but you just won't take it."

"Think about it."

After Qi Zhiyu finished speaking, she stood up, took two steps, stopped, and advised, "Also, don't use those little tricks. It's pointless."

The crown prince suddenly looked up, almost in a daze, as Qi Zhiyu's figure disappeared through the door.

The door was wide open, and the wind blew in, taking away the warmth from his entire body.

She knows!

She knew he had prepared a play for her father to see, intending to remind him that Qi Zhiyu hadn't taught the Da Rui soldiers martial arts, so how could he be so kind as to teach them the Bei Dian soldiers?

He prepared so much, yet he never even had a chance to use it.

He thought Qi Zhiyu would gradually win people's hearts and help Prince Ning sit on that throne, but now it seems... that's not the case.

The crown prince left dejectedly; he needed to think things through carefully.

Qi Zhiyu returned to the Ning Prince's Mansion, but Jiang Tinghao had not yet returned, presumably busy with the martial arts and medicine prescription.

With such a huge bait placed in front of him, Jiang Tinghao would definitely be eager to participate.

Improving the strength of the Northern Dian soldiers is not something that the Northern Dian king can decide on his own.

After all, the medicine in that prescription wasn't cheap.

"Princess, you seem very happy?" Luo Yu asked curiously, looking at the princess who always had a smile on her face.

"Of course I'm happy." Qi Zhiyu stretched. "I'm really a thrifty person."

"Using the money from northern Yunnan to build a highly elite team for Da Rui is truly a good idea."

Luo Yu: "..."

"Princess, what if Prince Ning and the others realize what's happening?"

Qi Zhiyu looked at her amusedly: "Will it be too late then?"

Luo Yu: "...Princess, are you using Northern Yunnan as fertilizer?"

"Don't say that," Qi Zhiyu shook her head. "We are all subjects of Da Rui, it's too formal to say that."

"All I can say is that we need to give them a sense of belonging. If they want to return to Da Rui, they have to show some sincerity."

Luo Yu didn't know what to say.

Just as Qi Zhiyu had predicted, those soldiers who hadn't followed the proper training methods did indeed run into trouble.

The imperial physicians were at a loss, and in the end, they could only follow the prescription given by Qi Zhiyu and force-feed them the herbal medicine.

After taking the medicine, their lethargic and near-death symptoms all disappeared.

They even felt better.

Only now did Jiang Tinghao truly believe that what Qi Zhiyu said was true.

"Father, it seems that those soldiers really can only learn the first level of the technique."

When Qi Zhiyu wrote the prescription for him, she noted this in the prescription.

She indicated that if they forced themselves to practice the later martial arts techniques, and something happened again, she wouldn't be able to save them.

Seeing that his father remained silent, Jiang Tinghao said, "Actually, we can also have them follow Qi Zhiyu's suggestion and practice breathing exercises before martial arts."

Since it has been confirmed that what Qi Zhiyu said was true, then the martial arts manual she wrote at the beginning was also true.

If I really practiced according to that... wouldn't it be possible...?

"Practicing martial arts can lead to qi deviation and even demonic possession," the Crown Prince said in a deep voice. "This is especially true for the more advanced the martial arts."

"Soldiers are here to fight on the battlefield, not to roam the world."

"There's absolutely no need to take that risk."

Jiang Tinghao felt uncomfortable upon hearing this.
