Transmigrated into Li Chengqian, he effortlessly ascended the throne and became emperor.

Iron hooves kicked up yellow dust, and banners obscured the azure sky above Renzhi Palace.

With the ruthless determination to "never return until Loulan is conquered" and the fanaticism to obtain the position of crown prince, Li Shimin led his army to march towards Qingzhou.

His father went to the front lines to earn military merits and seize the throne, so he, as the son, couldn't just sit here and wait like a salted fish.

Although Li Yuan is now forced to rely on Li Shimin and may have made a solemn promise to establish a crown prince, the old man is easily swayed and is a typical stubborn mule.

Historically, Li Jiancheng and Li Yuanji's greatest skill was their "pillow talk" diplomacy.

If they can't handle something, they just let the concubines in the harem spread rumors.

Especially Consort Yin and Consort Zhang, who were inseparable from Li Yuan and often caused trouble for Li Shimin.

Now that Li Shimin is gone, the Renzhi Palace is in a power vacuum.

If those women were allowed to take advantage of the situation and constantly complain to Li Yuan that "the King of Qin is too murderous" and "if the King of Qin ascends the throne, my son and I will likely die," then history would repeat itself.

He can't compete with his father's connections or his military achievements, but when it comes to charming others and providing emotional value, Li Chengqian's current body has a unique advantage.

After all, it has the inherent succubus attribute; if not now, when?

"Your Highness, the sun is too strong. Let's go back inside." The little eunuch beside him carefully held up the umbrella, afraid that the precious young master would get sunburned.

Li Chengqian turned around, and the scheming in his eyes vanished instantly, replaced by a pool of clear water about to weep.

"I'm not going back inside."

"I'm going to keep Grandpa company."

……

Li Yuan's sleeping quarters.

The ice cubes in the ice jar emitted a cool breeze, but it couldn't quell the restlessness in Li Yuan's heart.

Although Li Shimin had been dispatched, Li Yuan still felt like he had a sword hanging over his head.

Can Yang Wengan really quell the rebellion? Did Dalang really participate?

If Erlang wins, will he really depose the eldest son and establish the younger one in favor of the younger?

Just then, a series of light footsteps came from the entrance of the palace.

Li Yuan frowned, about to reprimand which ignorant servant dared to disturb him, but when he looked up, the curse that was about to come out of his mouth got stuck in his throat.

In the backlight, a small figure was seen struggling to carry a sandalwood food box over the high threshold.

Because the threshold was too high, he stumbled and almost fell, but he held onto the box in his arms tightly.

It was Li Chengqian.

The gloom in Li Yuan's eyes dissipated almost entirely in an instant. He beckoned, "Yu Nu? Why did you come alone? Where are your servants?"

Li Chengqian raised his head upon hearing the sound.

"Grandpa..."

Li Chengqian walked quickly to Li Yuan's side, and without bowing, placed the slightly heavy food box on the table, then hugged Li Yuan's knees with his two soft little hands.

"Aye is gone."

Li Chengqian pouted: "When Father left, he specifically pulled Yu Nu's ear and gave her some instructions."

Li Yuan's heart softened. He reached out and stroked the silky black hair, asking, "What did your father tell you?"

Li Chengqian sniffed and rubbed his cheek against Li Yuan's palm, like a cat trying its best to please its master.

"Father said that he went to fight bad guys for the Tang Dynasty and could not stay by his father's side to fulfill his filial duties."

"Father told Yunu to take good care of Grandfather. He said that Grandfather has been in a bad mood lately and has not been eating well. He asked Yunu to bring Grandfather his favorite cheese to try."

As he spoke, Li Chengqian opened the food box as if presenting a treasure.

Inside was a bowl of chilled cherry shortbread, its red and white colors translucent and glistening, making it incredibly appetizing.

Li Yuan was stunned.

He looked at the bowl of cheese, then at his well-behaved and sensible grandson, and his eyes welled up with tears.

In fact, he knew that with Li Shimin's rough and unrefined personality, his mind was full of military strategy before he set off, so how could he have thought of such a detailed matter?

This was clearly the child's own filial piety, yet he still wanted to attribute the credit to his father, who was probably eating sand somewhere at the moment.

What an understanding and heartbreaking child!

Li Yuan said "good" twice, his voice a little hoarse, "Second Brother is thoughtful, but our Yunu is even more thoughtful."

Li Chengqian knew when to stop. Instead of continuing to emphasize Li Shimin's virtues, he clumsily picked up a silver spoon, scooped up a spoonful of cheese, stood on tiptoe, and brought it to Li Yuan's lips.

"Grandpa, eat this. It's cool and refreshing. It will make you feel better."

Li Yuan opened his mouth and took it in. The sweet milky aroma, along with the tartness of the cherry, exploded on his tongue. The heat that surged from the bottom of his heart was actually suppressed by this spoonful of cream cheese.

"Is it delicious?" Li Chengqian blinked his big eyes and asked expectantly.

"Delicious! This is the best cheese I've ever had." Li Yuan smiled from the bottom of his heart, and the wrinkles at the corners of his eyes even smoothed out a bit.

In the days that followed, Li Chengqian remained quiet and stayed quietly by Li Yuan's side.

When Li Yuan was reviewing memorials, he would kneel on a small table beside him and grind ink with an ink stick in a very professional manner.

Occasionally, ink would splatter on his face, turning him into a little kitten, but he wouldn't even notice. He would just smile foolishly at Li Yuan, making Li Yuan laugh so hard that he would personally take a handkerchief to wipe his face.

When Li Yuan took a nap, he would take a large palm-leaf fan and kneel by the couch to gently fan himself.

When Li Yuan was upset, he would run around with his short legs, serving tea and water, and occasionally uttering a funny remark he had heard from somewhere, which would make Li Yuan laugh heartily.

Sure enough, this physical shielding method was extremely effective.

On the afternoon of the third day, Consort Zhang, who was usually the most favored, brought a bowl of lotus seed soup that she had personally cooked to the palace gate.

"Your Majesty, I heard that you have had a poor appetite these past two days, so I specially..."

Before he could finish speaking, he saw Li Yuan lying on the ground, playing a novel game called "Flying Chess" with Li Chengqian without any regard for his image.

"Hey! Grandpa, you cheated! How come you skipped again!" Li Chengqian pointed angrily at the chessboard, his rosy face turning bright red.

"Hahaha! All's fair in war! I call this speed the key to war!" Li Yuan laughed so hard his beard trembled, completely losing his imperial majesty and looking exactly like an old man next door teasing his grandson.

Hearing the commotion at the door, Li Yuan didn't turn around, waving his hand impatiently: "Take it away, take it away. Can't you see I'm busy? Don't disturb Yu Nu's enjoyment!"

Zhang Jieyu's meticulously painted face froze instantly as she stared in disbelief at the old woman and the child, the lotus seed soup in her hand seeming to have turned into a hot potato.

Normally, His Majesty would be half-hearted if she just acted cute, but today, because of this little brat, he didn't even glance at her?

Li Chengqian poked his head out from under Li Yuan's armpit and gave Zhang Jieyu a big smile.

The smile seemed innocent and pure to Li Yuan, but to Zhang Jieyu it was full of provocation and mockery.

"Your Highness, please return. Your father-in-law said he will be fighting with Yunu until dawn today."

Zhang Jieyu was so angry that she gritted her teeth, but she could only force a smile and leave.

Having chased away the flies, Li Chengqian continued to diligently work on increasing his favorability rating.

He not only played along, but also took charge of brainwashing Li Yuan.

But he never directly mentioned Li Jiancheng or Li Shimin; instead, he told stories.

He talked about how Emperor Yang of Sui killed his brothers and how Emperor Wu of Han doted on his crown prince, but he always spoke in a childlike, innocent tone.

"Grandpa, why does the book say that the man named Huhai wanted to kill all his brothers and sisters? Wouldn't it be better if everyone ate cheese together?"

At such times, Li Yuan would fall into a long silence.

Looking at his innocent and carefree grandson, who only thought about "the whole family eating cheese together," and then thinking about his eldest son who was going on a hunger strike in the wheat rice pavilion and causing chaos, Li Yuan's heart swayed more and more.

Yes, if Jiancheng had half of Yu Nu's obedience and understanding, if Jiancheng could be like this child, with affection in his heart, how could the Tang Dynasty have come to this?

Before we knew it, seven days had passed.

During those seven days, it was as if Li Yuan was making up for all the time he had spent with his children in his entire life.

He even had the illusion that there was no mutiny or rebellion in Renzhi Palace, and that he and his precious grandson were enjoying family bliss together.

Unfortunately, there are no "what ifs" in this world.
