After the son finished telling his experience in Xiangxi, he begged Lu Fang to save himself, and he also wanted to honor his mother and give his mother a pension.

However, all this can't be achieved after all, the Gu worm's toxin has completely invaded his brain, and the return of light is the last function of his body, allowing him to fight to the death, but this time cannot last forever.

After Lu Fang learned the important news he wanted, he asked the old woman to spend more time with his son, and he already knew through his pulse that this young man had now run out of gas, and he was afraid that he only had one breath left.

The old woman hugged and wept with her son, who even wanted to untie the chains and help his mother in the fields.

It's a pity that such happiness is always short-lived, and this young man still didn't hold on after all, and suddenly spurted out a mouthful of blood from his mouth, the color of the blood was like mixed with ink, red and black, very terrifying.

Under Lu Fang's gaze, the young man finally died in his mother's arms.

When the old woman saw that her son was still gone, the huge gap made her faint crying on the spot.

When Lu Fang saw this scene, he was very worried but couldn't do anything, after all, practicing medicine to save people and rejuvenating him with his magic hands could not save everyone.

Life and death are also situations that they often need to face.

However, Lu Fang remembered the Gu worm in Xiangxi, which made him quite interested in it.

Later, Lu Fang traveled all the way south, and met more and more people who were bitten by Gu worms on the way, these people had different symptoms, but they had all been to Xiangxi and had the experience of being bitten by insects.

All those who have survived, without exception, have all died, and none have survived.

This made Lu Fang shudder at the harmfulness of Gu worms, and he finally decided to go to Xiangxi in person to study the poisonous insects of Gu worms and understand that this incurable disease could not be allowed to spread further in the Central Plains.

Hundreds of years ago, the Xiangxi region was far from developing now, and there were no roads in and out of Xiangxi, so all people had to cross mountains and mountains, cross dense forests and streams and rivers in order to enter the mysterious and barbaric Xiangxi.

Before entering Xiangxi, many people nearby, including the senior brother who heard about this incident and came in person, also persuaded him that Xiangxi is a place where the barbarian clan lives, and many places are not civilized, and there are poisonous insects everywhere, and there is miasma, and those who enter it will die for life.

Even the princes were secretive about this land, and they were unwilling to set foot on it easily.

But Lu Fang had already made up his mind, he said goodbye to his senior brother, took the jade pendant given to him by the master brought by his senior brother, and personally wrote a letter to the master.

At that time, the roads in Xiangxi were closed, and the connection with the Central Plains could only rely on camel caravans to transport some silk and spices, and transport some gold, silver and herbs.

Sometimes I walked for seven or eight days in a row, and there was not a single house nearby, but poisonous insects and beasts, and poisonous miasma swamps could be seen everywhere, and if I was not careful, I would die on the side of the road, and there was not even a person who collected the body.

Those caravans that entered the land of Xiangxi were all outlaws or fantasists who wanted to get rich overnight, but reality finally taught these people a vivid lesson, and most of these people died in it.

On both sides of the rugged mountain road leading from the Central Plains to Xiangxi, you can see white bones exposed everywhere, some of which have been eaten by vultures, which is extremely tragic.

In this case, Lu Fang dared to go alone, and had to admire his courage and his dedication to treating diseases and saving people.

He wants to go deep into Xiangxi to find out where the Gu worms are and find a way to cure the Gu worms.

After Lu Fang entered Xiangxi, there was no news, after all, there were few people who went to Xiangxi, and it was not easy to find someone in the 100,000 mountains.

In this way, it was three years since Lu Fang disappeared, and in the past three years, many people have forgotten him except for his senior brothers.

In the past three years, the battles between the princes of the Central Plains have increased significantly, the etiquette has collapsed, and the world has sought change. The princes also asked for the previous policy and accelerated the annexation war, and the world was full of gunsmoke, the people were in exile, and the people were struggling to make a living.

During this period, in order to speed up the progress of the war, the princes used witchcraft and directly used it against the enemy, resulting in an increase in the number of deaths due to Gu worms year by year.

At this moment, Lu Fang, who had been in the land of Xiangxi for three years, walked out of the barbaric land.

Everyone was surprised by his sudden appearance, because after years of silence, not many people could recognize that the bearded and barbarian man in front of him was a master disciple of Guiguzi.

At that time, the two Qin and Jin countries were at war, and Lu Fang's senior brother served for the Jin State, and the Qin State, as an opponent, got a national teacher who knew witchcraft out of nowhere, who could call the wind and rain and was powerful.

Before the war, he put Gu worms in the water source of the Jin barracks, so that countless soldiers of the Jin State fell ill.

In addition, as the main combat force, many warriors fell ill, and the Jin State could not withstand the attack of the Qin State, and the battle line completely collapsed.

The battle situation on the front line was critical, but the barracks, which were the main fighting forces of the Jin State, were infected with unexplained diseases, and in the face of the aggressive attacks of the Qin State, the Jin State could only retreat again and again, and the situation was very critical.

Senior Brother Lu Fang, as the Minister of State, was also very busy in the face of this tricky situation.

He took the opportunity to lose his head at any time, and ordered the entire Central Plains to find a famous doctor, as long as he could treat the symptoms of the Jin soldiers, he would be rewarded with a thousand taels, and only by restoring the combat effectiveness of the Jin soldiers could they have the opportunity to retreat the Qin soldiers and regain the lost territory.

Unfortunately, despite the heavy reward, although a person claiming to be a famous doctor came to treat him, the soldier's symptoms did not improve in the slightest, but the condition became worse and worse, and the soldiers in the entire barracks vomited and diarrhea, and their bodies were paralyzed and weak, and their skin was black.

The barracks were stinking, mosquitoes and flies were everywhere, and all kinds of soldiers who could not be treated in time died in the barracks, like purgatory on earth.

The king of Jin received the edicts of impeachment from the ministers one after another, and in a fit of rage, he dismissed Senior Brother Lü Fang from the post of prime minister, abolished him as a concubine, and sent him to cure the diseases of the Jin soldiers within three days, otherwise he and all his relatives would be executed.

Senior Brother Lu Fang didn't dare to slack off, and hurried out of the city to find a countermeasure.

If you want to solve the situation within three days, it is not easy to talk about, the cause of this strange disease is unknown, and after the onset of the disease, it is like being cast by some spell, the whole person is paralyzed and decadent, and he can't get up again.

Time passed day by day, and in a blink of an eye, it was the last time requested by the King of Jin, and the forbidden army that was walking with him to prevent him from escaping had already shackled him and was ready to escort him back to the capital of Jin to be executed.

The road to heaven is endless, perhaps fate should not be extinguished, Senior Brother Lu Fang met Lu Fang when he was escorted back to Beijing.

Faced with this familiar and strange person, it took a long time for the senior brother to recognize the person in front of him as his junior brother.

When the brothers met, the two did not hug each other and cry, but had a tragic atmosphere of saying goodbye before they died.

The senior brother asked Lu Fang to help him bring a message to the master as a dying farewell.

But what the senior brother didn't expect was that this junior brother, who hadn't seen him for a long time, actually said that he had a way to treat these soldiers.

The junior brother entered Xiangxi and disappeared for three years, and this time he returned suddenly, and the senior brother couldn't take care of chatting with each other. Maybe this is just a delaying tactic by the junior brother.

However, with the attitude of trying, he was escorted to meet the king of Jin, and under Lu Fang's arguments, the king of Jin promised to give him a chance, if he couldn't do it, both of them would be executed.
