Li San saw that Lu Tong's face was slightly melancholy, and he didn't know how to speak, so he could only slowly follow behind Lu Tong, and then, the two of them went shopping for a long time, and they also encountered many rare materials and spiritual flowers and spiritual grasses, but Lu Tong didn't buy them, not that Lu Tong lacked spirit stones, but that he didn't lack any materials at this time, to be exact, he didn't encounter any materials that he lacked, all the materials for refining Qibao Dingtianding were too cherished and in huge demand, it was not at all such a scale, what would appear at the level of the trade fair, even the auction of zuihou could not appear。

In the blink of an eye, Lu Tong had visited most of the fair, except for the unknown dark yellow smooth stone that he bought at a low price, he didn't encounter anything that could make him happy, Lu Tong was looking for a place to rest for a while, but suddenly saw a mortal young man running quickly in the direction where he was.

"Li San, the poison on your mother's body has flareed up again, what are you still doing here......?" The young man came to Lu Tong's side and shouted at Li San, and when he saw Li San standing beside Lu Tong respectfully, he immediately stopped his words abruptly.

"What? What are you talking about? The poison on my mother's body has flare up again, didn't she just take medicine yesterday?" Li San was also anxious when he heard what people said, and his face was full of embarrassment.

"Li San, since your mother is sick, let's go home and have a look! Lu Tong listened to the words of the visitor, looked at Li San's anxious expression, and spoke.

"Thank you, Immortal Master, let's go. When Li San heard Lu Tong say this, he bowed to Lu Tong as if he had been amnestied, turned around and ran.

But after running a few steps, he suddenly quickly turned back, knelt in front of Lu Tong with a "plop", and held the two spirit stones that Lu Tong gave him yesterday with both hands.

"Li San, what are you doing here?" Lu Tong saw Li San like this, thinking that Li San was going to return the spirit stone, his face sank, and he asked coldly.

"The immortal master is above, and I also asked the immortal master to save Li San's mother, these two spirit stones are not enough, Li San is trying to find another way. Li San hurriedly replied.

"What's going on? Lu Tong frowned and said to Li San.

But Li San knelt on the ground to make a long story short, and quickly said his mother's condition, it turned out that Li San's mother was accidentally bitten by a poisonous insect the year before last, although many treatments, but still did not improve, I don't know why, every once in a while, will be poisoned, life is worried, if it is not for Li San is quite capable, looking for herbs in many ways, and even through some channels to buy some monks used elixir for his mother to detoxify and cure the disease, his mother may have died of poison.

It was this time that Lu Tong got two spirit stones, and Li San also wanted to find an opportunity to buy some elixirs used by monks to treat his mother's illness, but he thought that his mother was suddenly poisoned, Li San was also in a hurry, and he wanted to go home to take care of it, but he thought that Lu Tong was a bold and kind-hearted immortal master with a good temper and a high rank, and for his mother, Li San had the courage to pray.

"Alas, it's rare that you have a filial piety, lead the way in front of your head, I'll go and take a look!" After listening to Li San's introduction, Lu Tong sighed, and unconsciously thought of his mother, I don't know if she is okay?

"Thank you Immortal Master, thank you Immortal Master, thank you Immortal Master...... , this spirit stone also asks the immortal master to accept it. Li San kowtowed like garlic, and at the same time raised the two spirit stones in his hand and handed them to Lu Tong.

"Keep it for yourself, let's leave quickly!" Lu Tong didn't even look at the spirit stone, and said.

Li San got up directly, didn't even have time to pat the dirt on his clothes, and quickly led the way in front.

It didn't take long for Lu Tong to follow Li San to a nice courtyard, and when Li San came back, a young woman and a boy about four or five years old quickly came out of the main house, with tears on his face, and the boy hugged his mother's thigh tightly, looking at Lu Tong with a look of surprise.

"How is my mother? Didn't you just take the medicine yesterday?" how could this be?" asked Li San to his wife.

Li San's wife didn't speak, just shook her head and hugged the boy tightly.

Li San was startled and looked at Lu Tong with pleading eyes.

"Lead the way in front of the head. At this time, Lu Tong didn't dare to delay in the slightest, and said directly to Li San.

The two quickly entered the inner room, Lu Tong observed slightly, the entire inner room was well organized and spotless, and there was an old woman in her fifties and sixties lying on the bed, with a black face, obviously poisoned.

"Immortal Master?" Li San opened his mouth and called Lu Tong.

Lu Tong waved his hand, signaled Li San not to speak, and then slowly walked to the side of the bed, slowly picked up Li San's mother's palm and looked at it, as a person who cultivates immortals, Lu Tong still has the ability to treat ordinary mortals, and after a little checking, Lu Tong took out a low-grade Qinghan Pill and sent it into Li San's mother's mouth, waited for about a dozen breaths, and then motioned to Li San to help his mother sit up, and then patted Li San's mother lightly behind her back, Li San's mother opened her mouth and spit out a small black beetle the size of half a little thumb, as soon as the little black beetle landed, she was about to run away quickly, Lu Tong sneered, stretched out his hand, and pinched the little black beetle in his hand, shook in front of Li San's wide eyes.

"This insect is called the black leech blood worm, after biting people, it will burrow into the human body, attach to the heart to suck blood, for itself to grow slowly, and at the same time spit out toxins and eventually kill people. Then the fire flashed in Lu Tong's hand, and the black leech blood worm turned into ashes.

"This immortal master has taken a detoxification elixir for your mother and removed this poisonous insect from your mother's body, I believe that in less than two days, your mother will be restored. Lu Tong looked at Li San's mother, whose face had turned ruddy, said casually, and then walked outside the house.

Li San slowly put his mother on top of the bed, turned around quickly, came outside the house, and bowed down with his wife and son.

"Immortal Master's great grace, Li San is toothless and unforgettable, dog, hurry up and thank Immortal Master, thank Immortal Master for saving your grandmother's life. Then, pressing his son and wife together, he kowtowed his head with a bang.

When he heard Li San call his son 'dog egg', Lu Tong smiled slightly, thinking in his heart, this world is really big and small, I can't imagine that the word 'dog egg' can be heard among mortals, and when he saw that Li San's son didn't understand the world and just kowtowed, Lu Tong hurriedly stopped Li San and said: "Okay, Li San, the child is still young and ignorant, don't scare the child, let them go into the house to see the old man!"

"Thank you, Immortal Master. Li San cried with joy, stood up, and commanded his wife, and then, Li San's wife led her son slowly to the back room, and Li San's son didn't know why Weishenme, his eyes flashed, and he kept turning his head to look at Lu Tong.

"Okay, Li San, your mother's illness is no longer serious, the immortal master has gone back, you don't have to follow me these days, stay at home and take good care of your mother!" Lu Tong said to Li San after seeing Li San's wife and son leave.

"Immortal Master, wait a minute, there is a small thing here that may have some effect on you, Li San will go and get it, please take a look." Seeing that Lu Tong was leaving, Li San hurriedly spoke, and then turned around and ran towards the back room.

Lu Tong smiled slightly, and sighed in his heart, this Li San is indeed filial, this leech blood insect bites people and enters the human body, it will take people's lives in less than two years, ordinary mortals will die of poisoning unknowingly, I didn't expect Li San's mother to live for three years, I think it took Li San a lot of effort to extend his mother's life to the present.

As for what Li San said would be useful to him, Lu Tong just smiled in his heart, just a mortal, even if he is a human spirit among mortals, what else will Lu Tong need now, I think Li San didn't want to go, and found some slightly spiritual family heirlooms to give to Lu Tong, all of which were grateful.

Lu Tong was about to leave, Li San hurriedly came out of the house, holding an unknown animal skin in his hand, caught up in a few steps, handed the animal skin to Lu Tong, and said, "Please take a look at the immortal master and see if this thing is useful to the immortal master." ”
