A letter from his mother was an unprecedented experience for Zhang Zhao.
He suddenly remembered his mother before time travel. She was a pungent and attentive rural junior high school teacher. Most of her energy was given to his school and students, so that the relationship between mother and son was relatively weak.
Zhang Zhao has never eaten a few meals cooked by his mother since he was a child. He basically cooked it in the school cafeteria. When he grew up, there seemed to be fewer words between mother and son, and all communication was settled with a few words on WeChat. .
That's fine, at least she should be able to bear the pain of her son's sudden disappearance.
As for this letter from Zhang Zhao's biological mother, the Song family, he read it back and forth many times, and an unknown feeling lingered in Zhang Zhao's heart.
The content of the letter was very simple. Mrs. Song said that she had not seen her son for five years. Now Cao Yuanzhong, the governor of Shasha, was acting as a guarantee, allowing Zhang Zhao to return to Dunhuang so that mother and son could be reunited for a while. She also attached a handwritten copy of the letter. And he often recited the "Prajna Paramita Heart Sutra" to him.
"Avalokitesvara Bodhisattva, walking in the deep Prajnaparamita for a long time, saw that the five aggregates are all empty, and survived all the hardships. Relic, color is not different from emptiness, emptiness is not different from color, color is emptiness, emptiness is color, and the same is true for feelings, thoughts, and consciousness."
Zhang Zhao took out the "Prajnaparamita Heart Sutra" handwritten by Song and kept chanting it. A woman's kind face flashed in his mind.
"My son, since ancient times, when emperors were in trouble, it was difficult for their descendants to have a good death. From now on, you must listen to the words of the loyal man. If you miss your mother, just recite the meaning of my Buddhist scriptures! You must remember that if your mother hand-writes the Buddhist scriptures and gives them to you, she will definitely There is a catastrophe coming, so be careful!"
Be careful! Zhang Zhao sighed, and a teardrop suddenly appeared in the corner of his eye.
In fact, he and the Song family had never met. It turned out that Zhang Zhao had no deep impression of the Song family and was even a little resentful.
But at this moment, thousands of past events suddenly came to mind, and the loving face that had been blurred for a long time suddenly appeared in front of him.
Yang Kongmu looked at Zhang Zhao with tears falling from the corners of his eyes and felt happy. As a close confidant of Shasha Governor Cao Yuanzhong and the chief official of the Kongmu Academy who was in charge of the household registration album and personnel secrets of the Guiyi Army, he certainly knew what Cao Yuanzhong was planning. .
As long as Zhang Erlang goes to Dunhuang, he will have no chance of escaping. The little boy dared to have someone stab him. Master Kong Mu almost fainted from the pain. You deserve to suffer the pain of being cut into pieces!
As for Cao Shishi, he is Cao Yuanzhong's man. The life and death of Cao Yuande's son cannot be said to be unimportant, but King Tuoxi doesn't care about it, so he can only leave it to fate.
"Ma Yaozi!" Zhang Zhao shouted to Ma Yaozi in the distance with tears in his eyes.
When Yang Kongmu heard the word "horse kite", his anus tightened, but when he looked at Zhang Zhao's red eyes, he felt a little more at ease. He was crying like this. He must be going to Dunhuang, right?
"Hurry up and give Mr. Kong Mu another blow on his right shoulder. How ugly it is! One side is bandaged and the other is not bandaged. It's not coordinated at all." Zhang Zhao pointed at Yang Kongmu's uninjured shoulder and said.
"Erlang Junrao...!
oops! Kill me! "
Yang Kongmu's face was twisted in pain, what kind of person is this! Even before the tears dried on his face, someone stabbed him.
"Yang Kongmu, go back and tell my brother Yuanzhong to stop causing trouble and ask him to send someone from the Cao family to talk to me. If Cao Shisi wants to survive, he must show his sincerity quickly.
I will leave for Khotan in ten days. I can’t guarantee what will happen if I delay it any longer. "
After Zhang Zhao waved his hand, Dunzhu took a piece of four-layer linen cloth and tied it around Yang Kongmu's eyes. Then the deputy of the third team, who was promoted from the herdsman, picked up the thin Yang Kongmu. and went down the mountain.
"No! Ouch~! No! Ouch!" The smell of sweat and irritation that can kill people, coupled with Dunzhu deliberately pushing his shoulder against Yang Kongmu's stomach, and even jumping up and down when going down the mountain, directly caused Yang Kongmu to side I vomited while calling for help, and by the time I got down the mountain, I would probably have vomited out the gall.
. . . .
"Second cousin! It's burning! It's burning! Oh! Just some charcoal, sulfur and ground stones can really burn!"
Cao Shishi, who was said by Zhang Zhao to not guarantee what would happen, shouted with joy when he saw Zhang Zhao coming in.
This silly boy! His face was blackened by smoke, and the hair on his forehead was almost burnt, but he was still enjoying it, as if he had discovered a new world.
"What kind of ground stone? You don't even know saltpeter? I really wonder what your Cao family taught their descendants? They don't all teach you to worship Buddha and chant sutras, right?"
Zhang Zhao was speechless, but he was really not pretending, he was really surprised.
The thing Cao Yanming is working on now is gunpowder, one of the four famous inventions in Chinese history. As one of the three most powerful weapons for time travellers, Zhang Zhao of course has to 'invent' gunpowder, but his invention should be called Improve.
Don't think that gunpowder in the Tang Dynasty is a very strange thing. In fact, it is not strange at all.
Gunpowder had already been used when Yang Xingmi of Huainan attacked Yuzhang more than 20 years ago. Of course, the gunpowder at this time had insufficient burning speed and weak reaction, so it could not be used for blasting, but could only be used for arson.
But no matter what, it’s an exaggeration to say that Cao Yanming, a member of a distinguished family, doesn’t even know saltpeter! Zhang Zhao walked up to him unceremoniously and grabbed his ears.
"Have you never seen the secret of the golden elixir of the Supreme Saint Ancestor? Haven't you heard of the essentials of the true essence? Don't you know the method of subduing the fire?"
"Ouch! It hurts! Cousin, these things you are talking about seem to be Taoist classics, right? But our Dunhuang is a Buddhist country! Where can I find Taoist classics?
But if my second cousin can name it, there must be one, so bring it to my nephew to observe! "
Damn it, forget about this. Why can't those eminent monks also learn how to make alchemy? At least they can cultivate some chemical talents!
Looking at Cao Yanming and Zhang Zhao who looked expectantly, he spread his hands and said, "I have only heard of these. Where can I get the book for you to read and learn?"
"Cousin, please remember some of it and tell your nephew about it!"
"I don't remember, I don't want to know the meaning of reading!" I really don't remember. He, Zhang Zhao, can only remember the names of these two Taoist classics. It was when he went abroad to play full-armor combat that he was told by Asan who insisted that gunpowder was invented in India. I wrote it down after I suffered internal injuries due to anger.
He was going to use this as a retort when he met that stupid Asan again, so he wrote down the name, but he really hadn't read it.
However, Zhang Zhao still remembered the proportions of black powder, which were 10% sulfur, 15% charcoal, and 75% saltpeter.
But the idea was good, but when it was put into practice, Zhang Zhao found that it was not that difficult.
First of all, he did not have precise weights and measures, so the proportions were inaccurate.
Secondly, the purity of the sulfur and saltpeter are different, and the thickness and degree of carbonization of the charcoal are also different. I know the ratio of black gunpowder, but the things that come out are all strange.
What the hell, when mixing gunpowder with love, you need to first standardize the purity of sulfur, saltpeter, and charcoal. But how can Zhang Zhao have the time? He is currently busy winning the hearts of his subordinates and has no time to do research.
"Cousin, you don't ask for a thorough explanation of such a world-famous classic? It's simply a waste of resources!"
Cao Yanming tilted his head and looked at Zhang Zhao with an "I really despise you" look. He was so angry that Zhang Zhao gave him a kick on the butt.
