If this method can be widely adopted, countless people will benefit from it.

Although he watched all of this from the sidelines, and Qu Qingxi's actions seemed very simple, Gu Liangsheng knew in his heart that there must be some skill involved.

The bamboo tube is thin and sharp; if used improperly, it can easily injure a patient's throat.

Gu Liangsheng turned to look at He Liufeng, who was standing quietly to the side. Seeing no surprise in his eyes, he knew that He Liufeng must know everything.

He Liufeng, whom he considered a friend, had kept it a secret from him for so long. If he had known earlier that Qu Qingxi was such a skilled doctor, he would have become friends with Qu Qingxi long ago and discussed medical techniques together, Gu Liangsheng thought angrily.

After feeding Qingzhu the medicine, Qu Qingxi carefully took out the bamboo tube and gestured for Qingdai to help Qingzhu sit for a while before she lay down, so that she wouldn't vomit up the medicine that had just been given to her.

"Alright, the situation has stabilized now. Qingdai, just take good care of her. Tomorrow morning, cook some thin porridge, remember it must be very thin. Scald this bamboo tube with boiling water and then feed it to her using the method I just described."

Qu Qingxi patiently instructed Qingdai. Seeing Qingdai looking at the bamboo tube in her hand, Qu Qingxi carefully taught Qingdai several times how to use it without hurting anyone.

Gu Liangsheng also took the opportunity to come closer and carefully learn how to use it.

Qingdai was very clever. After Qu Qingxi explained it to her briefly, Qingdai nodded in understanding.

"Your Highness, I understand. Thank you, Your Highness." Qingdai looked at Qu Qingxi gratefully.

"Okay, take good care of her. If you get tired, find someone to take your place." Qu Qingxi instructed, glanced at He Liufeng, and then got up and left, with He Liufeng following her.

Once he was sure that Qu Qingxi and He Liufeng had gone far away, Gu Liangsheng stepped forward, grabbed Qingzhu's hand that was hanging by the bedside, and began to take her pulse. Sure enough, Qingzhu's condition had improved a lot.

Qu Qingxi remained silent the whole way, and He Liufeng didn't say anything either. When they returned to their room, the two lay down to rest.

After an unknown amount of time, Qu Qingxi gently got up, turned her head and glanced at the person next to her. He Liufeng's breathing was even, indicating that he had entered a deep sleep.

Qu Qingxi tiptoed out of bed, walked to the cabinet, changed her clothes, and saw the black cloak hanging next to her. On a whim, Qu Qingxi picked it up, tied it around her waist, and turned to leave.

Not long after Qu Qingxi left, He Liufeng, who had been fast asleep on the bed, opened his eyes, glanced at her in the darkness, and then got up and dressed. It was obvious where Qu Qingxi had gone.

Upon arriving at the Crown Prince's residence, Qu Qingxi made no attempt to conceal herself, swaggering in through the main gate and slowly walking further inside.

Qu Qingxi's appearance instantly attracted the attention of the Crown Prince's secret guards. The person in the courtyard was dressed in black, with a high ponytail and a black mask covering her face, making it impossible to see who she was.

"Who is so bold as to break into the Crown Prince's residence at night?" someone shouted.

However, the figure in the courtyard did not stop walking and continued to walk forward, as if he had not heard what was said earlier.

Seeing that the man did not speak, the leader slightly raised his hand, and soon two people flew down to block Qu Qingxi's path.

Qu Qingxi looked up at the two people in front of her, her eyes extremely cold, like the silent ice of a ten-thousand-year-old iceberg.

The two men were startled by Qu Qingxi's gaze, but they quickly recovered and charged at her with their swords drawn. Qu Qingxi flicked her sleeve and threw the two men in her direction, and they instantly fell to the ground, lifeless and bleeding profusely.

The others were also stunned by what they saw, not expecting this person to be so skilled.

The leader of the secret guards then signaled for a few more people to go down.

Qu Qingxi had only taken five steps forward when she saw about ten more people flying towards her. Qu Qingxi's expression remained unchanged, but she instantly conjured several poisoned hidden weapons in her hand.

Having witnessed the scene just now, these men saw the other party raise his hand and immediately prepared to use their swords to block the hidden weapon.

Who knew that while they were fast, Qu Qingxi's hidden weapons were even faster, and in an instant, five more people fell to the ground, losing their breath.

The remaining men gasped, exchanged glances, and without hesitation stepped forward, intending to kill the person in front of them before he could throw a hidden weapon.

However, they still underestimated Qu Qingxi's strength. In just one move, the arrogant group of people were also lying on the ground, unable to get up.

Upon seeing this, the leader of the secret guards immediately sent someone to inform the Crown Prince of the situation, and then signaled the archers to prepare.

He refused to believe that the man below could dodge all the arrows in the Crown Prince's mansion.

The leader of the secret guards pressed down with his right hand, and instantly, arrows from all directions flew towards the person in the center of the courtyard, densely packed and carrying killing intent as they approached Qu Qingxi.

Qu Qingxi remained completely calm. Only when the arrows flew close to her did she raise her cloak with her right hand. Instantly, all the arrows that had just flown past disappeared, and Qu Qingxi showed no signs of injury.

The guards were shocked and didn't know what was going on. The archers were even more stunned. If they hadn't shot the arrow themselves, they probably wouldn't have believed what they were seeing.

Where did those arrows go?

Everyone present was confused.

The leader of the secret guards refused to believe it and ordered the archers to shoot arrows again. This time, they didn't just shoot one arrow, but each of them shot all the arrows in their bodies at that person.

A continuous stream of arrows flew towards Qu Qingxi. Those who saw it felt their scalp tingle. Anyone hit by an arrow would surely be riddled with holes.

But to everyone's astonishment, all those arrows mysteriously vanished when they were presented to Qu Qingxi, as if they had never existed.

Everyone present was terrified, staring intently at the person in the middle of the courtyard. They even began to suspect that the person in front of them was not human at all, but a ghost.

Dressed in eerie black, he walked forward silently with measured steps, and could even make arrows disappear. Everyone was startled; this was something no human could do.

The leader of the secret guards was also somewhat flustered. What was going on? Was it a human or a ghost?

Before anyone could figure it out, the man flicked his cloak, and instantly, a dense barrage of arrows shot towards the guards present.

They were so shocked that they were completely unprepared and never expected that these arrows would appear and shoot back at them. Moreover, these arrows were faster, and a large number of people were directly hit and died with their eyes wide open. They died without ever understanding what those arrows were.

Some of the more skilled and quicker-reacting guards managed to dodge the arrows that were shot at them.

The leader of the secret guards was both shocked and furious as he looked at the large number of corpses lying on the ground. He was shocked by the strength and fear of the newcomer, and furious because so many people had been dispatched, yet the newcomer was unharmed, while his side had suffered heavy losses and countless casualties.
