"Just like these two in heaven, they also want to live a hundred years and be immortal!"

"But now, look at what they are doing?"

Li Chengqian's voice suddenly rose, and he pointed at the helicopter hovering in the sky, with a crazy light in his eyes.

“They are enjoying the joy of flying and being watched and cheered by everyone.

And I can only stand here, leaning on a cane, like a useless person!" His voice was full of jealousy and resentment.

Chengxin looked at Li Chengqian, and an inexplicable fear surged in his heart.

Ever since he broke his leg, the prince has changed completely.

Not only does the behavior become abnormal, but the personality also becomes moody and even crazy.

He knew that Li Chengqian was no longer the calm and composed prince, but a madman blinded by jealousy and anger.

"Your Highness, please calm down." Cheng Xin tried to comfort him. "Your body still needs rest. You shouldn't get too excited."

"Calm down? How do you expect me to calm down?"

Li Chengqian turned abruptly and glared at Chengxin, "My position as Crown Prince is in jeopardy. How can I remain calm?"

"What did Sizi and my father promise me? They promised me to research that gene as soon as possible so that I could heal my leg injury?"

"But look at them now, what are they doing? They are enjoying themselves, enjoying the admiration of the people!"

Li Chengqian's voice was trembling, anger and disappointment intertwined in his heart.

"My legs are broken just like that. I've become a cripple forever!"

Chengxin silently endured Li Chengqian's anger. He knew that any words would be pale at this moment.

The prince's leg injury was an eternal pain in his heart and the root cause of his drastic change in personality.

"They promised solemnly that they would develop a treatment as soon as possible."

Li Chengqian continued to roar, "But what about now? The Sizi is flying in the sky.

My father is lost in the cheers. Who still remembers me, the crippled prince?

Chengxin was frightened by Li Chengqian's crazy eyes and took a step back, but he still tried to remain calm.

"Your Highness, your position is not as precarious as you think. The Empress is still here, and she will always support you."

"Mother?" Li Chengqian sneered, "Ah! Mother won't live long!"

"Not to mention that my mother has respiratory disease, I even caught someone putting drugs in her medicine a few days ago!"

"It's obviously Qingque, absolutely Qingque! He can't stand seeing a loser like me occupy the position of Crown Prince."

"He didn't hesitate to send people to kill my mother, just to take my place as soon as possible."

Li Chengqian's voice became increasingly cold, and every word seemed to be squeezed out from between his teeth, filled with hatred.

Chengxin was speechless, he knew that what Li Chengqian said was true.

The Queen was indeed attacked by evil people, this is an unavoidable fact.

"What I want is a lasting legacy, the great Tang Dynasty!"

Li Chengqian suddenly roared, his voice echoing in the empty courtyard, "I can't just sit there and wait for death, I must act!"

"If I don't take action now, not only will my position as Crown Prince be in jeopardy, but my mother will also be killed!"

Chengxin looked at the crazy Li Chengqian, his heart filled with helplessness and worry.

He knew that Li Chengqian had been blinded by power and hatred at this moment, and was no longer the prince he once admired.

"Your Highness, what are your plans?" Chengxin asked cautiously, although he was full of uneasiness in his heart.

But he knew he had to stand on Li Chengqian's side, no matter what his choice was.

A hint of madness and determination flashed in Li Chengqian's eyes.

He slowly approached Chengxin and whispered, "Of course I will follow your majesty's example and stage another Xuanwu Gate Incident!"

"Didn't Qingque want the position of Crown Prince? I'll send him to hell and let him fight with the King of Hell!"

Chengxin was startled when he heard this.

He knew that Li Chengqian was on a path of no return, and if he failed, he would be doomed.

However, he also knew that Li Chengqian would not listen to any advice at this moment.

"Your Highness, I am willing to serve you, even if it means going through fire and water!" Chengxin took a deep breath and said solemnly.

Li Chengqian looked at Chengxin, a glimmer of satisfaction flashing in his eyes.

He patted Chengxin's shoulder and said, "Okay, with your help, I will definitely accomplish great things!"

Chengxin felt a chill in his heart, he knew how heavy the burden on his shoulders was.

He took a deep breath and said in a deep voice: "Your Highness, since we have decided to embark on this path, we must make all preparations.

I have a plan that may be able to help us."

"Hurry up and tell me!" Li Chengqian said anxiously.

"We can use firearms." Cheng Xin slowly uttered these words, with a gleam in his eyes.

"Your Highness, have you forgotten the firearms battalion in the hands of His Highness Jinyang?"

Upon hearing this, Li Chengqian's eyes flashed with confusion, then suddenly realized. "You mean, the Firearms Battalion controlled by Sizi?"

"That's right." Chengxin nodded, "The firearms battalion under His Highness Jinyang is equipped with many sophisticated firearms with enormous power.

If we can gain the support of these firearms, it will greatly increase our chances of victory."

Li Chengqian pondered for a moment, a gloomy look on his face.

He knew that the firearms battalion in Sizi's hands was indeed a powerful aid, but it was not easy to obtain this aid.

Although Sizi and he are siblings, Sizi has gradually distanced herself from him since he broke his leg.

"Sizi is now alienated from me. How could she easily hand over the Firearms Battalion to me?" Li Chengqian said with a frown.

Chengxin smiled slightly, with a cunning glint in his eyes.

"Your Highness, this is indeed not easy, but it is not impossible. I have a plan that may allow the Firearms Battalion to be used by Your Highness."

"Oh? What's your idea?" Li Chengqian asked curiously.

Chengxin leaned close to Li Chengqian's ear and whispered his plan.

After hearing this, Li Chengqian's eyes flashed with surprise. He patted Chengxin's shoulder and praised:

"Chengxin, you are indeed a wise man! If this plan succeeds, I will definitely reward you handsomely!"

Chengxin smiled modestly, but was secretly proud of himself.

He knew that if his plan succeeded.

Not only can it help Li Chengqian, but it can also bring him great credit.

…

On the other side, the gyroplane, under the control of the little princess, landed again in the square in front of Ganlu Palace.

The moment the wheels of the plane gently touched the ground, Li Shimin felt an indescribable excitement in his heart.

He stepped out of the gyroplane, his feet firmly on the ground, but he seemed still immersed in the shock of flying in the sky just now.

The ministers waiting around came forward one after another to pay their respects, each of their faces filled with excitement and awe.

They witnessed with their own eyes the emperor soaring in the sky on the magical "fairy boat".
