Twenty years ago, he was in a much worse situation than he is now.

At that time, the senior brother Nong Qingshan was recognized by everyone as the next heir to the palace master. Among the three senior brothers, the master disliked him the most and distrusted him the most. But he finally got the position of the palace master of Shennong Palace.

Now that he is already a highly respected and respected palace master of Shennong Palace, how can he not be able to deal with a person who was once a defeated general and is now powerless?

He repeatedly thought that Nong Qingyun had captured Nong Qingshan's only weakness - his daughter.

But it is not easy to find a person who has been missing for seventeen or eighteen years, and if he cannot be found for ten or eight years, he must wait forever? No, he was never a waiter.

After a night of hard thinking, he had a perfect plan hatched in his mind.

Nong Qingshan also closed his door, eagerly waiting for the night to come. He will confirm a question that has plagued him for twenty years - how did Li Yulu get poisoned?

This question had gone from a sharp thorn to a part of his body over the years, into his blood, into his flesh. He didn't know where this thorn was, but as long as he thought of Li Yulu, Nong Qingyun, Master and Shennong Palace, he felt that ten thousand pierced his heart.

Nong Qingshan had doubted all the people in Shennong Palace, including his master Nong Pingfeng.

After all, Shennong Palace and the Jiuli clan have always been opposed, Nong Pingfeng turned Li Yulu away, in order to prevent his favorite big apprentice who wants to pass on the position of palace master, he is deeply trapped, and it is not impossible for Nong Pingfeng to poison Li Yulu.

The third junior brother Nong Qinghai has always been loyal and honest, and he persuaded Nong Qingshan to listen to his master and give up his relationship with Li Yulu; While in front of the master, he begged the master to forgive the senior brother for going astray for a while. Nong Qingshan ruled out the possibility that Nong Qinghai poisoned Li Yulu.

The second junior brother Nong Qingyun City Mansion is extremely deep and ambitious, and he has never shown any thoughts about Nong Qingshan taking Li Yulu back to Shennong Palace, and no one can see through his heart.

However, Nong Qingshan is the biggest obstacle for Nong Qingyun to take over as the palace master of Shennong Palace, so there is a great possibility that Nong Qingyun poisoned Li Yulu in order to drive away Nong Qingshan.

The poison in Li Yulu seems simple, but it is not.

What she has is a poison that is very similar to a poison called "Heavenly Maiden Scattered Flowers" in Shennong Palace. Although the name of "Heavenly Maiden Scattered Flowers" is beautiful, its toxicity ranks third in the poison list of Shennong Palace, and it is a poison that seems to be soft, but can torture the poisoned person to death.

It slowly erodes the internal organs of the poisoned person, and every noon and child, it will swim all over the body of the poisoned person, sometimes extremely itchy, sometimes cone-hearted. Poisoned people often scratch their skin because of itching, and self-harm because of the pain that penetrates into the bones.

In addition to the characteristics of "Heavenly Maiden Scattered Flowers", the poison in Li Yulu also has the characteristics of blistering lips and tongue, violent muscle contraction, and loss of consciousness.

Nong Qingshan had never seen this kind of poison, and he had no idea where to start, so he begged the master to help detoxify it, but was ruthlessly refused.

He had no choice but to refine the antidote based on his own experience, and several attempts ended in failure. The toxicity on Li Yulu's body continued unabated, and he didn't dare to test Li Yulu easily.

After Li Yulu's death, Nong Qingshan never stopped searching for all kinds of poisons, especially in foreign neighbors outside the Central Plains, hoping to find poisons with the same symptoms as Li Yulu's poison.

In the Mid-Autumn Festival this year, a Tatar came to Haihui Temple to travel, because of his love for the Central Plains culture, he was obsessed with it, and he spent three days and three nights sleepless discussing Buddhism, martial arts and Chinese herbal medicine with Nong Qingshan.

Nong Qingshan was very proficient in martial arts and Chinese herbal medicine before he became a monk, and after he became a monk, he studied Buddhism, so he had a very pleasant conversation with this Tatar.

During this period, the Tatars mentioned a plant called "Black Black Sea", which is extremely poisonous.

Its toxicity is mainly in rhizomes, but also in other parts. It only takes a few moments for the poisoned person to develop foaming lips, general spasms, confusion, vomiting, red skin, and blue complexion.

The Black Sea is most toxic in late autumn and early spring, and in the Mobei grassland, livestock often die due to accidental ingestion of the Black Black Sea.

Hearing this plant, Nong Qingshan was shocked.

Is there any connection between the poisoning symptoms of taking Black Wuhai and the poison in Li Yulu?

He recalled that more than 20 years ago, Master had sent three of his disciples to various places to explore herbs. He went to the southwest region, and the second senior brother Nong Qingyun went to the Mobei region.

Did Nong Qingyun bring back the Black Wuhai Sea from Mobei? But all the people in Shennong Palace didn't know about the existence of the Black Black Sea, could it be that Nong Qingyun secretly planted it elsewhere?

Why did Li Yulu not die immediately after being poisoned, but delayed for nearly a year until she gave birth to her daughter? Did Li Yulu fall victim to the poison of the Black Black Sea?

All these questions made him sit like a pinprick and couldn't sleep at night, and the originally painful wound was like being eaten by thousands of ants. Nong Qingshan could not wait any longer and was determined to return to Haihui Temple to find out the truth.

Just as he was about to leave, Nong Qingyun came to Haihui Temple unexpectedly. After a contest with Nong Qingyun, Nong Qingshan was rightfully invited to Shennong Palace by Nong Qingyun as a guest of honor, and unknowingly entered the enemy camp, and his mind to find clues to Li Yulu's poisoning was hidden in a place that no one knew.

When night fell, Nong Qingshan was dressed in black as always, masked with black cloth, and walked to the forbidden place in the back mountain with black cloth shoes.

He came to the place where Nong Qingyun had brought him a few hours ago, in front of a small brown flower.

Standing in the daytime, he looked at the place that shocked him. His heart sank, and the black sea was gone!

He took a deep breath and walked slowly in that direction. In spite of his restlessness, he cautiously crossed the delicate flowers, trembling away from the thorns of his teeth and claws, leaving no trace of his visit.

In a small clearing as black as ink, he stopped. One of the few black black plants that appear during the day mysteriously disappears into the night.

He crouched down, stretched out his hands, and greeted him warmly with a leaf. Heiwuhai, it turns out that you are still there! Nong Qingshan was overjoyed, picked a piece, and put it in front of him.

The moon hid behind the clouds, its faint halo barely giving the earth a little light. Through the faint light, Nong Qingshan saw the dark leaf in front of him clearly.

It was so dark, it was literally part of the night. No wonder every time he passed by at night, he couldn't see it. Nong Qingshan picked another piece and put it in his arms.

The joy receded suddenly, and a heart-rending pain fell from the sky, breaking through the darkness and enveloping him tightly. He let out a low roar and swung his palm in an attempt to destroy all of the Black Seas and make them pay for their blood.

But are they the source of sinful debts? They are nothing but weapons of the wicked.

Nong Qingshan's liver and intestines were broken, and the internal force was forced back to the dantian from the palm of his hand, and his eyes showed a firmness that he had never seen before, and a powerful voice echoed in the fading moonlight.

Nong Qingshan returned to the palace from the forbidden land in the back mountain in despair, although he tried to stay sober and calm, the involuntary panic still wandered in his gestures, running unscrupulously in every pore of his body, and he had to stop from time to time to concentrate his breath.

On the morning glory corridor, as he greedily breathed in the cold watery air, he suddenly noticed that his heavy breathing was mixed with whispering.

He was shocked, and his heart, which had just been calm, beat violently again, and all his efforts were in vain.

He held his breath. The voice was getting closer and closer to him: "Look at it! I have a stone in my hand, and if I stomp my foot, it will grow four feet and run around the corner. ”

Nong Qingshan could tell that it was the sound of the stone, and although they had never dealt with each other, the stone's unobtrusive style had to attract his attention, and besides, Shi Shazhu also accepted him as a disciple.

Nong Qingshan breathed a sigh of relief, in his eyes, Shi Xin had no city, was innocent and simple, and would not pose any threat to him.

Who else is this person? Nong Qingshan didn't dare to show up, and poked his head out near the corner. The stone was walking towards him alone, and there was no one else.

"Stone, it's so late, you still don't go to sleep? Who are you talking to? ”

"Wow!" The stone took a step back and patted his chest, "Zen Master Zhiyin, you scared me!" Why are you here? Do you see my stone? ”

"Stone, I see you!"

"Oh, it's not for you to look at me, it's for you to see if there's a little rock beside you."

The stone couldn't laugh or cry. Although his name is easy to write, it used to make him proud of his peers when he was two years old, but it is so ordinary that it can be seen everywhere, so ordinary that everyone has his name on their lips, so ordinary that everyone thinks that the stone cannot be his name, which annoys him.

"Oh! Little stones! Nong Qingshan glanced down, and a small stone at his feet was lying there quietly with a white light, "I saw it!" He bent down and reached out to pick up the little stone.

"Don't move!" The stone shouted, as if the stone at the foot of Nong Qingshan was not a dull and dull stone, but a poisonous snake staring at him, "Don't worry, I will let it obediently return to my hand by itself." ”

"Huh? It can't be, how can there be such a miraculous thing? "Nong Qingshan's cooperation is seamless. Shi Shazhu has performed countless tricks in front of him, and he knows how to arouse the enthusiasm of the performers.

"Haha!" The stone held its head proud, "I don't even look at the stone, and he will return to my hand." Come! The stone shouted, and the stone emerged from the palm of the stone like a bamboo shoot, and there was nothing at Nong Qingshan's feet.

"Good!" Nong Qingshan clapped his hands and applauded, "Your level is very high, hurry up and go back to sleep!" ”

"Zen Master Zhiyin, my level is really high?"

"Of course, Shi Shazhu is nothing more than that."

"Ouch, I don't dare to compare with Master. Zen master, I'll change another one for you. I can turn what is in you into my hands, believe it or not? ”

Shi Shi only cared about his own interest, stretched out a hand to prepare, and did not pay attention to Nong Qingshan's intention to be a spectator.
