Gu Yi took a cold look at these "filial" good sons of his family.

Knowing that they are really thinking about Gu Nuoer.

Otherwise, Gu Yihan would have taught them a lesson one by one.

He asked the eighth prince to check Mu Yuan one last time.

Gu Yihan said domineeringly and decisively: "Don't talk nonsense, I have already thought it through."

"This flying kite can help you enter the city, but the distance is too short to fly into the palace, so after entering the city, I will find the highest landing point and jump down."

Except for the Eighth Prince, the others couldn't help being surprised.

Father is really courageous.

The Eighth Prince took basic security measures for Gu Yihan.

After checking, he took out the colored paper in his arms to measure the wind direction.

"Father, wait for a while, and when the wind direction is stronger, you can set off."

Taking advantage of this time, Gu Yihan confessed to his sons again.

"After I left, the second child and the third child returned to Zhang Xuhu's side. After entering the city, they might use his connection to enter the palace. You said that the barracks exploded, and my other two sons and I disappeared."

"When I'm not around, you all have a good relationship with Zhang Xuhu, and help if you can."

The second prince and the third prince bowed their heads: "Yes."

Gu Yihan said again: "The fifth and eighth think of a way to sneak into the city within two days and join me."

The Fifth Prince and the Eighth Prince nodded.

At this time, the wind was howling, and the Eighth Prince looked at the swaying colored paper.

He hurriedly said: "Father, the time has come!"

Gu Yihan nodded: "Let's go."

The Fifth Prince and the Eighth Prince, one on the left and the other on the right, grabbed the wooden kite and started running.

After reaching the steep steep hill, the two brothers let go at the same time.

The wooden kite flew steadily towards the city with the wind.

The second prince squinted and watched Mu Yuan leave straight and quickly.

He turned to look at his three younger brothers.

"From now on, we will fight on our own. When we gather together, we are like a ball of fire, and when we are scattered, the sky is full of stars."

"The dark guard came to report earlier that the interior of Xili has become a mess. Third brother, fifth brother, and eighth brother, protect yourself."

He stretched out his hand: "Rescue my sister as soon as possible, let's go home together!"

The third prince, fifth prince and eighth prince also stretched out their palms, overlapping each other.

The four brothers have serious faces, majestic momentum, and firm eyes—

"Take my sister home!"

Next, the four brothers discussed and assigned countermeasures.

The third prince rushed back to the barracks first, rescued Zhang Xuhu, and won more trust from him.

The second prince helped count the wounded and contacted all the barracks in Liuzhou.

The fifth prince wanted to follow the dark guards to check the terrain, and they wanted to enter the city as soon as possible to cooperate with Gu Yihan.

The Eighth Prince stayed on this backside hillside and used the remaining materials to assemble gunpowder in case of emergency.

They proceed methodically.

But at this moment, Gu Yihan's wooden kite flew over the high city walls of Kyoto.

A soldier stationed above was startled when he saw this scene in the cold snow and strong wind.

Then he took a closer look and immediately shouted: "Come on! Someone is going to break into the city with a wooden kite!"

At this time, the wind was blowing heavily, and Feiyuan was already shaking unsteadily.

Gu Yihan tightened his cold eyebrows, he made a decisive decision, took out his dagger, and cut the rope wrapped around his body.

Jump directly towards the highest stand on the city wall.

Almost the moment he landed, Feiyuan crashed into the opposite observation deck with a "bang".

Such a violent noise attracted the attention of patrolling guards around.

"Something jumped from the sky, go and see!"

Hearing their shouts, Gu Yihan's eyes flashed coldly.
