Li Shimin waved his hand impatiently.

Go!

"When we set up camp tonight, come to my central command tent and give me a good talk about this grandson's military training strategy!"

"promise!"

Cheng Yaojin quickly finished handling the military affairs, sent out scouts far away, and selected a campsite for the night. He then eagerly awaited nightfall so he could go to His Majesty's tent to discuss the eldest grandson's military training strategy.

Although he only glanced at it briefly during the day, that one glance was enough to shock him.

He had a premonition that the strategy drafted by his eldest grandson might concern the military and political affairs of the Tang Dynasty for the next hundred years!

As long as one can be one step ahead and know the contents of the strategy, the prosperity of the Cheng family for generations can be guaranteed!

Cheng Yaojin finally made it to nightfall and, after urging his men to finish setting up camp, rushed to Li Shimin's central command tent.

At this moment, Li Jue had already written down the strategy for training troops and was lying on the bed drinking sour plum soup. When he saw Cheng Yaojin arrive, he hurriedly handed the strategy to him as if presenting a treasure.

"Uncle Cheng, you've come at the perfect time! Quickly take a look at my military training strategy!"

Upon hearing this, Cheng Yaojin first looked around, and seeing that His Majesty was not there, he immediately asked in a low voice.

Where is His Majesty?

"His Majesty has gone to visit Changsun Wuji..."

Seeing that His Majesty was not present, Cheng Yaojin immediately began to earnestly advise Li Jue.

"Eldest grandson, could you please tone down your temper a bit in the future?"

"You know perfectly well that His Majesty is notoriously petty. You criticized him in front of so many people, making him lose face. You're just asking for a beating!"

As Cheng Yaojin finished speaking, Li Jue coughed.

"Your Highness, even if you cough, I will still speak!"

"You cannot act recklessly just because His Majesty favors you..."

"One must know that serving a ruler is like serving a tiger!"

Just as Cheng Yaojin was about to offer his earnest advice, he suddenly heard a sinister voice behind him.

"Who are you calling a tiger?"
