I have already established my power and prestige, so how did Li Shimin come back to life?

His eyes were fixed on Li Ji, revealing his expectation for the answer and his concentration on the march.

"Your Majesty, the army is almost at Qingshui. After crossing Qingshui, we will be out of Shaanxi Road."

Li Ji answered respectfully, his eyes looking firmly ahead, his eyes revealing his familiarity with the marching route.

Li Ji was well aware that this march was a heavy responsibility and that every step could not go wrong, so he remained vigilant at all times, determined to justify the huge military expenditure of His Royal Highness the Crown Prince.

He silently recalled the marching route map in his mind, checking whether there was any missed link.

Every landmark and every stretch of the journey was crystal clear in his mind. He knew that he was carrying the trust of His Majesty and the lives of the soldiers, and he could not slack off in the slightest.

Li Shimin nodded slightly, but couldn't help feeling emotional in his heart.

During the twenty days of marching, he felt deeply that he was indeed not as good as he was in his youth.

Although his crotch was not worn out due to long hours of riding every day, he could see the inside of his thighs were red every time he took a break. The burning sensation was like being on fire.

He looked at his swollen thighs, feeling a little helpless. Time is merciless, and the tireless self who once fought all over the world seems to have gradually faded away.

He felt a sense of powerlessness spreading in his heart. He was an emperor, but he could not resist the erosion of time.

There were makeshift tents all around, swaying slightly in the wind. The campfire outside the tents was still emitting wisps of green smoke, which were traces left by the soldiers boiling water and cooking.

The ground was covered with a mess of footprints and horse hoof prints, showing the busy passage of the army.

He looked at all this and knew the hardships of war, but for the stability of the Tang Dynasty, he could not retreat in the slightest.

He told himself that even if his body was not as good as before, his will must be as strong as steel. For the people of the Tang Dynasty and for the dignity of the country, he must persevere.

Every pain is a test of his will, and he must overcome these physical discomforts as if they were enemies.

However, Li Chengqian was extremely well prepared for this expedition. Li Shimin was pleased with his son's attentiveness and was full of confidence in this expedition.

He knew that his son had made a lot of efforts in the rear for this expedition, which made him feel comforted that there was someone to carry on his legacy.

The army is equipped with a variety of novel medicines, which are neatly placed in the military doctors' medicine boxes, emitting a faint medicinal fragrance.

There was also a group of military doctors coming from Xianyang. Their tents were in a corner of the main camp, and the surroundings seemed exceptionally quiet.

Military doctors are usually taciturn. They are obsessed with studying medicines. The tables in the tents are filled with bottles, jars and various herbs, as if that is their whole world.

Li Shimin had had brief contact with them, and just from this brief exchange, he keenly realized that the medical skills of these military doctors might have surpassed those of the imperial doctors in the palace.

He had a plan in mind at that time. These military doctors were really capable, and Cheng Qian must make good use of them in the future to train more medical talents for the Tang Dynasty.

But after thinking about it, he felt that he was overthinking. Cheng Qian was so smart, and Xianyang Chen's medicine must have reached a new level.

The Tang Dynasty needs such talents who can save more soldiers' lives and make the Tang Dynasty's army stronger.

Outside the military doctor's tent, several unknown wild flowers swayed in the wind, as if adding a touch of vitality to these mysterious doctors.

Li Shimin looked at the wild flowers and felt that they were like the military doctors. Although inconspicuous, they had unique value.

After a full twenty days of marching, surprisingly, not a single soldier fell behind due to illness, which was unthinkable in the past.
