When the Second Prince Huyan Bie was five years old, he suddenly had a strange illness and his body became worse and worse. In the desert, Huyan Bie had already lost the possibility to ascend to the throne.

When the Second Prince was fifteen, he took the initiative to ask the Emperor to send him into the army and conceal his identity as the Second Prince. This stay of his lasted thirteen years.

And in these thirteen years, Huyan Bie had never returned to the Imperial City once, never seeing his royal parents or royal brother again.

However, she did not know why Huyan Bie did not know that she was poisoned. However, she was certain that the murderer's intention for poisoning her was related to the highest level of cultivation.

Since ancient times, there had never been anyone who did not wish to be the son of an Emperor. As long as there was enough temptation and benefits, even brothers could instantly turn hostile. This was human nature.

In this world, what could be more tempting than a superior position?

When he was five years old, the already fifteen year old First Prince had already seen through everything. Letting him deal with a five-year-old child, was that as easy as flipping his hand?

As for why the Emperor and Queen of the Desert would allow this matter to happen, it was very simple. They only had two sons, Huyan Bie, and the First Prince was already an adult, so even if it was a normal person, they would choose to protect the murderer of the poison, let alone the always most heartless family.

It was a pity that Huyan Bie had been kept in the dark for so many years. For the past 13 years, he had been diligently guarding the border for the desert. While living an extremely miserable life, he still had to endure the pain of the poison.

Gu Shiyi could think of it, but he of course wanted to as well. It was just that he did not believe that her royal father and mother, as well as her elder brother, who doted on him the most, would treat him like this.

However, when they thought of the inhuman torture he had endured for the past 13 years, a strong sense of unwillingness and hatred arose in Huyan Aobo's heart. He did nothing, he even had no intention of fighting with his brother.

If he was wrong, he could only be born in the royal family.

Seeing the flames of hatred in Huyan Bie's eyes, Gu Shiyi's lips unconsciously raised upwards, and she slowly walked to Huyan Bie's side and sat down. She took out a needle bag from her sleeve, and had Huyan Bie place her hand on the table.

Seeing Huyan Bie's arm that was as thin as a match, Gu Shiyi's eyebrows could not help but jump. If it was not for Huyan Bie's exceptional perseverance, he would not have been able to live until now.

The poison that Huyan Bie was infected with was a chronic poison called Jiu Li. Just two years ago, when she first arrived here, she already heard that the general had recruited a doctor. Although she did not intend to save him, she was exceptionally interested in this general's illness.

Furthermore, once, when the moon was dark and the winds were high, Gu Shiyi had disguised herself and entered the army camp, sneaking into Huyan's other tent, and took a pulse for the sleeping Huyan. Furthermore, outside the tent, he heard the symptoms of Huyan Bie's cough, and immediately determined the poison that Huyan Bie was infected with.

Most of the poisons in this world were extracted from poisonous plants and animals, but there was a small part of it that was extracted from various poisonous natural substances, such as mercury, or sulfur, and this gradual separation was one of them.

Gu Shiyi was good at detoxifying, but what she was good at was detoxifying poison from plants and animals, and this was exactly the kind of poison Silver Snow Snake would restrain.

That was why she dug a cellar and raised this poisonous substance, wholeheartedly developing this Antidote. Just a few days before Gu Morou appeared, this Antidote had only just been developed.

Gu Shiyi then inserted a row of silver needles into all the acupuncture points on Huyan Bie's body, and this silver needle was not even a silver needle, the last method Gu Shiyi researched was to use poison as an antidote, thus the tip of the silver needle had already been painted with poison that could restrain the poison from leaving.

After Gu Shiyi pierced all the silver needles, in just a short moment, Huyan Bai felt a tingling sensation spread to his limbs and organs from where the needles pierced. After about half an incense stick of time, the tingling turned into a sharp pain, and in that time, the tingling and the sharp pain alternated, and continued for an entire day and night.

To an ordinary person, their life would be worse than death, but to Huyan Bie, it was just a small piece of food. The pain brought by this acupuncture was far from the pain he felt when he was free from the poison.

After twelve hours, Gu Shiyi's eyes were unmoving as she stared at the silver needles on Huyan Bie's body. Just as the end of the silver needles started to release traces of black blood, Gu Shiyi pulled out all the silver needles and pierced them into Huyan Bie's other heart veins with lightning speed, using her acupuncture to gather the poison from Huyan Bie's body and guide him to the next location. After finishing, Gu Shiyi took out an antidote pill for Huyan Bie to consume.

As such, the poison on Huyan Bie's body was treated, and the only thing that was left was to properly recuperate and heal his body. Gu Shiyi wiped the sweat off her forehead with her arm, and looked at Huyan Bie's sleeping face, and her heart finally heaved a sigh of relief.

Although she had been very relaxed while performing acupuncture, only she understood the nervousness in her heart. The poison that was used to detoxify the blood seal throat was highly toxic. If she had been slower by a moment, Huyan Bie would have died from the poison.

It was fortunate that she had the acupuncture and gathering technique that Sun Jinxing had taught her. Otherwise, she would not have the confidence to use such a risky method to cure Huyan Bie of his poison.

The desert was desolate, the land was barren, and ordinary people did not even have food to fill their stomachs, let alone those valuable medicinal herbs. Although there were many merchants at the border, none of them sold medicinal herbs, and even if there were, Gu Shiyi did not want them. Gu Shiyi could only use those poisonous substances, but fortunately, she knew all of these things like the back of her hand.

If it wasn't for Situ Jing, how would she have known about acupuncture and moxibustion gathering?

She would take revenge for the Gu Family and she would find Situ Jing. But now, she had already taken the first step.

Before long, she would return to the Capital Xia and make those people pay with their blood!
