Chen Jinghao is now 20 years old, and he has spent seven years in Wanjiao Mountain. Ten Thousand Tribulation Mountain was his home before he went to Thang Long.

After the rain, the sky is clear, raise your head and look at the sky, the sun is like a fireball hanging above your head, the fire is scorching, there is no way to look directly, the air is boiled, the air waves are swept by, like steam, the surroundings are very quiet, there is no sound of birds and beasts chirping, such a hot weather, even these little things are hiding at home and do not want to go out.

Chen Jinghao gently wiped the beads of sweat on his forehead, and the rhythm of his breathing was obviously much faster than before.

He found a shade to rest for a few minutes, looked at the faintly visible mountain in the distance, a smile appeared at the corner of his mouth, and he couldn't help but be a little anxious in his heart, the last time he came back, it was two years ago, two years later, the Ten Thousand Tribulation Mountain still looks so majestic.

After just a short break of a few minutes, he got up again, patted the dirt behind him, and continued to walk forward, his pace was much faster.

At the summit of Chaoyang Peak sits a very elegant courtyard, surrounded by white mist, which should be scorching sunlight is offset by the cold of the mountain, and it becomes very bright.

The bluestone floor is very clean, and the steps on it are very crisp, the room is made of mahogany, so you don't have to worry about getting damp, and there are many beautiful pink flowers planted in the center of the courtyard.

"See the flowers?" Xiao Tiantian pointed to the flowers in the courtyard and said.

"See, it's pretty good." Wang Linlin replied, she obviously didn't understand what Xiao Tiantian meant.

"Those are big fireworks. Linlin. Du Lili laughed.

"Huh?" Wang Linlin suddenly understood, "Vietnam planted this so early? ”

"There are also in the Great Song Dynasty, and there are quite a lot of them, but they are only used as medicinal materials." Sun Hui said, "Many celebrities like Su Zhe have also used it." ”

Sun Hui told the girls that poppies have been cultivated in China for thousands of years. Many people think that opium was a product of imperialist colonial aggression imported into China in the late Qing Dynasty, but this is not the case. When it comes to opium, it is certainly inseparable from the cultivation and popularization of opium poppy, and the Diye Jia recorded in the "Tang Materia Medica" is a compound medicine introduced from Xirong and made from opium poppy, but such an imported product cannot be equated with opium poppy or even opium.

As early as the end of the seventh century and the beginning of the eighth century, the opium poppy has formed a small range of cultivation in China, and by the ninth century, the Hanzhong and Chengdu basins have begun to grow opium poppies. Thousands of miles of customers are sad today, and they first saw rice bags in front of the horse. ”

The rice sac flower is another name for the poppy, the poet is a native of Chengdu, he arrived in Hanzhong through the oblique oblique, saw the poppy, and produced a sense of intimacy at home. In the late Tang Dynasty, there was also a sentence in the "Thirty Miscellaneous Songs of Jiangnan" that "the blue draws the book with grass, and the red section of rice sac flowers", which shows that the opium poppy was planted in Jiangnan at that time.

However, at that time, the opium poppy was only blooming as an ornamental flower in everyone's field of vision, and there was no record of the opium poppy in the "Qianjinfang" of the Tang Dynasty and the "Cranial Fontanelle" of the late Tang and early Song dynasties, so it can be inferred that the doctors at that time had not fully recognized the medical value of the opium poppy.

In the Northern Song Dynasty, the planting range of opium poppy was further expanded, and the common people fully carried forward the excellent quality of "how to do it", and the poppy seedlings were used in vegetables and poppy seeds to satisfy hunger, and the "Buddha porridge" boiled into could nourish the lungs and stomach.

Su Zhe, one of the eight masters of the Tang and Song dynasties, once wrote "Two Songs of Planting Medicine and Seedlings? Planting Poppies": "In the west of the city, there are books. Outside the window, pine and bamboo are sparse. Pull out the thorns and open the furrow, and use Yujia vegetables. The furrow told him that the poppy could be stored. The poppy is as small as a poppy, and the corn is as thin as a poppy. It is planted with wheat and ripened with sacrifice. Miao Kan spring vegetables, really than autumn valley. It is made of milk and cooked as Buddha porridge. The old man is weak and has little to eat. Eating meat does not disappear, and eating vegetables tastelessly. Willow mallet stone bowl, fried with honey water. Defecate the mouth and throat, nourish the lungs and stomach. Three years of Dumen, Mo Shi repaid. The ghost monk is relatively forgetful. Drink a cup and smile happily. I came to Yingchuan, like visiting Lushan. ”

In the Southern Song Dynasty, the cultivation range of opium poppy was further expanded, and the common people continued to apply it, and found out the simple but practical information, and so on in the Jin and Yuan dynasties, the scope of application of opium poppy in medical treatment expanded a lot, in addition to being used for lung and stomach diseases, it also began to be used for cough, dysentery and other stubborn diseases, and used to relieve the poison of Jinshi. At this time, opium was still a precious drug, but because of its wide range of applications, it buried the hidden danger of abuse.

Because of this, in fact, Sun Hui was not particularly surprised to see poppies appear in Vietnam.

Chen Jinghao entered the courtyard and walked from a small door to the south of the east wing, he carefully looked at the steps of the verandah, and recalled everything before as he walked.

Walking to the door of the main house, I gently pushed the door open, the door was a little heavy, but there was no sound, he closed the door when he entered the house, and stood at the door without his eyes getting used to it for a while.

"Chen Jinghao?"

When he heard it, it was his junior brother Cheng Yijing.

"Is that you?"

"Oh, yes." Chen Jinghao reacted.

"You're also back to find the Secret Passage?" Cheng Yijing asked.

"What did you say?" Chen Jinghao was stunned.

"No wonder I came back so quickly, I seem to be really curious." Cheng Yijing laughed softly.

After laughing, Cheng Yijing said, "Why don't you arrest me?" ”

"......" Chen Jinghao was speechless for a while, not understanding why he said that.

Cheng Yijing cleared his throat and said, "Since you are also here, let's look for it together." Master must have gone to the secret room through the secret passage, and now he is likely to have left, so let's go find him. ”

When they were looking for the secret passage, they were very quiet, I don't know who came in to search before, the traces are still there, Chen Jinghao groped again, and almost tested the floor tiles with his waist. I don't know how long later, his back was so sore that he couldn't do it, so he found a place to sit on it, and happened to see a game of chess on the table.

Could it have something to do with chess? He carefully picked up the chessboard, but he didn't expect to pick it up as soon as he took it, and there was no reaction, it seemed that he was thinking too much. But...... This game seems to be interesting, so let's take a break. It is not easy for white to eat and rob, but white must win the robbery to live, and the loss will be great. Looking at the tricky chess game, he unconsciously fell into it, until Cheng Yijing's hand picked up the chess pieces and fell, and I immediately flew to block, this is a good chess! He was so excited that his heart was beating, and Cheng Yijing used the upper right as a robbery, he immediately dissipated, and he didn't want Cheng Yijing to dig in the air and play chess partially!

Chen Jinghao stared at the chessboard and was entangled, Cheng Yijing smiled in a low voice and sat on the table where the chessboard was originally placed, the table was not high, he was really relaxed and comfortable when he fell gently, Chen Jinghao glanced at him and continued to entangle, who knew that before his head was turned, the table turned silently.
