What Yuan Tiangang said is like a fantasy story.

When Du He heard this, he was a little surprised.

It can only be said that the lives of these two masters are too big, so they can escape.

Especially Qingfeng, the huge Uzi steel is a little more off, and he will not smash his legs, but his whole body.

Saying that, Yuan Tiangang walked up to Du He, took a deep look, and said with a serious expression: "Du He, you saved Qingfeng's life, and it is I, Yuan Tiangang, who owes you a life." ”

Saying that, Yuan Tiangang actually wanted to kneel down for Du He.

Du He couldn't stand this, and quickly helped Yuan Tiangang up.

"Lao Yuan, between you and me, there is no need to say this, it's just that after the breeze recovers in a few days, where will you go? Is it necessary to build a Qingfeng Temple? Du He asked curiously.

When Yuan Tiangang heard this, the corners of his mouth twitched, and he pointed at Du He and said, "My Yuan family's old mansion has been deceived by you, and I am now homeless." ”

Du He smiled: "You can't say that, you were willing to sell it to me at the beginning, why don't you point to gunpowder and smelt iron, why don't you stay and do things for me?" ”

Du He took a fancy to Yuan Tiangang's ability to smelt iron, this guy was obsessed with alchemy, but he had no intention of inserting willows, and mastered a large number of iron-smelting and steel-making skills.

Yuan Tiangang shook his head like a rattle, and said that he would not agree to anything.

Du He suddenly smiled mysteriously: "Young Master Ben never makes it difficult for others, no matter what, when Qingfeng is injured, you can leave, but, I'm afraid it won't be long before people in the world will know that you have a son, named Yuan Qingfeng." ”

Yuan Tiangang's eyes suddenly widened, and he looked at Du He incredulously: "You...... How do you know? ”

"No comment!"

"You're threatening me?"

Du He shrugged helplessly, "Did I say that I spread the news?" ”

Yuan Tiangang really wanted to beat Du He, but unfortunately he was not Du He's opponent.

After a while, Yuan Tiangang nodded helplessly: "Okay, I promise you to stay, but what can I do?" ”

Du He thought to himself, Young Master Ben likes the way you hate me but can't kill me.

He smiled and asked, "How did you get the iron I asked Lu Bu to bring back?" ”

Yuan Tiangang nodded hurriedly: "I spent more than ten years and paid a high price to buy the iron from the Persian merchants, and I originally wanted to build a Dan furnace, but I didn't expect it, and it almost hurt the breeze." ”

Duhe said: "The iron, or Uzi steel, is used to make the Dan furnace, but it is too wasteful, it is better to use it to make something more fun." ”

"What's that?"

"Cannon!"

Du He smiled mysteriously and said: "Old Yuan, you happen to be able to smelt iron and make gunpowder, it just so happens that I have an idea to build a cannon, are you interested?" ”

"What is a cannon?" Yuan Tiangang looked confused.

Du He pointed to a dirt mountain on the opposite bank and said, "The worst cannon, put it here, can blow up that small dirt mountain at once, what do you think?" ”

Yuan Tiangang didn't dare to imagine it at all.

"Is there such a powerful thing in the world?"

Duhe said: "There are no cannons in the world, but when I came to Duhe, there were." ”

Yuan Tiangang was a little curious and said, "Okay, Du He, since there is such a divine object, how can I not agree." ”

Du He smiled slightly: "Lao Yuan, don't be busy agreeing first, I have conditions, first, you and I must sign a confidentiality agreement, within five years, if you dare to leak the secret of the cannon, I can kill you at any time, second, your majesty joins the Datang Furniture Factory, in the future, I will build a high-tech laboratory for you to do all kinds of research, even if it is used for alchemy, it doesn't matter." ”

Hearing the second one, Yuan Tiangang's eyes lit up.

At this time, this old way still hasn't forgotten alchemy.

He agreed without even thinking about it.

Immediately, a confidentiality contract was signed, which can be regarded as a life and death contract, and Yuan Tiangang risked his life.

Early the next morning, he asked the workers of the furniture factory to build a house on the bank of the river as a base for making cannons.

……

A few days later.

Palace.

Li Er asked: "Zhao Yang, I asked you to invite Yuan Tiangang into the palace, I want to allocate money to build a Qingfeng Temple for him, and by the way, predict the fortunes of the country for me, why haven't you seen any movement for a long time?" ”

Zhao Yang hurriedly said: "Your Majesty, the slave went to the Datang Furniture Factory a few times, and also saw Yuan Tiangang's big event, he said, ......"

"What did he say?"

"Master Yuan Tiangang said that he is now busy exploring the truth of science, and he has stopped predicting the fortunes of the country!" Zhao Yang whispered.

Syllable.

Li Er threw the brush in his hand and smashed it on the ground: "...... Yuan Tiangang must have been bewitched by Du He, this bastard ......"

……

Meanwhile.

The Qingfeng Guan incident has spread all over Chang'an City.

Everyone is saying that the famous veteran Yuan Tiangang has practiced the Flying Ascension Pill and ascended to the Immortal, and when he left, he accidentally let out a fart and blew up the Qingfeng Temple.

Of course, many people don't believe it.

Near the West Market, a huge mansion suddenly appears on the corner of the street, this mansion has a luxurious and imposing courtyard, which contrasts sharply with the low buildings around it.

The most conspicuous were the four guards standing at the gate, all of them rugged, with a beard, wearing armor made of animal skins, and carrying a scimitar at their waists.

But anyone who passes by will avoid these fierce men when they see them.

Deep in the courtyard, in a room.

"Prince Gongsong Zanbu, we have inquired clearly, Duhe, the son of Lantian County, is the inventor of explosives, he presented the method of making explosives to His Majesty the Emperor, and obtained the title of the prince of Lantian County, and recently, there was an explosion in a Taoist temple outside the city, which became flat overnight, which made Chang'an City feel shaken, and it was also because of the explosives...... Prince, we can't wait any longer, now the Tang Dynasty is sharpening its knives at our border, just to occupy our land, take away our cattle and sheep, and rob our women! ”

A middle-aged man in a leather jacket with pigtails said respectfully to the young man sitting on the revolving wooden chair.

I saw that the young man was in his twenties, with a round head, a round face, and a pair of eyes that were small and exaggerated, as if two small beans were embedded in his face, and the hair around the head was shaved, only a handful of the top of the head remained, but it was messily scattered around.

The young man's real name is Gongsong Gampo, but his origin is not ordinary, but he is now the prince of Tubo, his father is the famous Songtsan Gampo, of course, at this time, the Tubo led by Songtsan Gampo, the strength is not strong, there is friction with the Tang Dynasty at the border, and occasionally there will be wars.

In his life, Songtsen Gampo admired the Central Plains culture the most, and he sent one of his sons, Gong Song Zanbu, to Chang'an City to learn Han culture.

After a while, Gong Song Zanbu stood up and said solemnly: "Du He is extremely cunning, if you want to kidnap him to Tubo and make explosives bags for us, there is only one chance, the more night the Datang Furniture Factory is, the more strict the guards, the best opportunity is in the evening, when everyone goes to dinner!" ”
