The black line on Ge Jingyi's forehead, what kind of eyes does the little girl have, is the poor road like a demon? Depressed, he said: "Girl, has the poor road ever harmed you? Why do you call me a demon? ”

Zheng Lin was a little frightened, and took a few steps back, "On the moonlit night of the last yuan, you threw out a black bump and blew up His Highness's friend into black charcoal, isn't it like those demons and monsters in the book?" So, isn't it a demon or something? ”

Ge Jing asked Cangtian speechlessly, although he has never been heard of by the world, but he is also at the foot of Sanqing Mountain and is praised by the local people, and the virtuous and respected Ge Immortal Master, has become a demon in the mouth of this little girl? Outrageous!

Consciously filtered the old often took apprentices down the mountain, shamelessly stealing the green vegetables in the people's vegetable fields, and then ran to cheat the villagers to eat and drink in the name of eliminating demons, and then cheated some money to go out to visit the famous mountains and rivers. Since then, www.biquge.info has won the honorific title of Ge Xianshi in the mouth of the local people.

"Don't see the same little girl!"

Ge Jing, whose personality was insulted, spat out, shook his sleeves and snorted coldly, and walked past Zheng Lin towards the hall.

Zheng Lin grimaced at Ge Jing's departing back, and muttered in a low voice: "What's the spirit, I want that Cheng Wuzhong to see you and have to pick up your skin." ”

"Giggle......" Thinking of the night of the last lunar month, the drunken Cheng Wuzhong was blown up by the black bumps thrown by the old way, and he was extremely angry, chasing after him in the crowded crowd with his legs, Zheng Lin couldn't help but snicker.

Li Yu put away the official document on the table and looked at Ge Jing who was striding forward with a smile.

This old Taoist spirit is really not ordinary, delicious and delicious for more than a year, but in the end he said goodbye without saying goodbye, leaving only a few vague gunpowder formula codex, and the promised date of the first moon night did not come as promised.

Now that he is here, he has no sense of self-shame, which makes Li Yu angry for a while!

Nuo is not entangled in everything, Li Yu doesn't have much energy and wastes manpower to pay attention to this old boy, otherwise, he has to send someone to search the whole world to arrest this old guy.

Ge Jing arched his hand and said with a smile: "Your Highness has not seen you in March, and your demeanor is becoming more and more prosperous!" ”

"Immortal Master, have you come to do it repeatedly?"

"A cultivator keeps his promise all his life!"

Ge Jing said solemnly, Li Yu frustrated his teeth, has he kept his promise after almost four months? Li Yu didn't bother to bother with him, the most important thing was gunpowder, did this old bastard find the best formula?

I'm still waiting for the explosives to blow up the city, and I'm going to blow up the strong walls that Silla has built on the border!

"In that case, I don't know how the Immortal Master's gunpowder is going?"

"Your Highness attaches so much importance to gunpowder, I wonder where Your Highness will use it after getting it?"

Ge Jing's expression was serious, and his inquiring tone was firm, which surprised Li Yu.

And where is gunpowder used? In addition to the fact that war is the greatest use for it, is it also used to make fireworks for fun?

It's just that this old Taoist suddenly asked this, I don't know what it means? Listening to his tone, Li Yu guessed that he must have made powerful gunpowder with the scriptures, and knew very well the power of gunpowder and its best destination. But with this question, could it be that his universal values are overflowing, and he is worried about the lives of Yidi Hulu around Anton?

Li Yu replied casually: "It depends on the power of the gunpowder, if it is small, it can only be made into a gadget to replace the firecrackers, and it will be blown up on holidays." ”

"What if it's powerful? Big enough to open mountains and crack rocks, killing and injuring people and animals within a radius of two feet! ”

"Then its best use is war!"

Li Yu replied categorically, and Ge Jingdu was stunned by his domineering momentum, and sighed: "It seems that His Highness's understanding of gunpowder is no worse than that of Poor Dao, and even looks farther." ”

"This is because you are just a cultivator, self-cultivation and pursuit of the Heavenly Dao Immortal Path, and the mundane in the world has little to do with you. And I was born into the royal family, and it is impossible to leave the ordinary from the moment I was born. The moment I was born, I assumed part of the responsibility for the fortunes of the Tang Dynasty and the rise and fall of China. Now that you are in this position, you have to learn to raise your head and let your eyes look farther. Isn't it too unfortunate for Nuo to have a muddy life? ”

"Hahaha! It seems that His Highness's ideals must be very ambitious! ”

Ge Jingshuang laughed and said, how many princes and grandsons of all dynasties will associate their birth with the dynasty and the rise and fall of China? Those who have a heart to win the throne are just greedy for the supreme imperial power, maintaining the world of their own surname, how many people have mentioned the rise and fall of China?

Today's Li Yu's answer is to convince Ge Jing's heart, but he has such a state of mind at the age of a young man, and it is difficult for him not to achieve a great cause in the future.

Li Yu smiled and said, "Immortal Master, can you tell me now, how is your gunpowder?" ”

It's a blessing or a curse, and it's a disaster that can't be avoided. If Li Yu disturbs the world for his own selfish desires, even if there is no gunpowder, it will not matter.

Ge Jingwei sighed: "The best formula for gunpowder that Your Highness wants is here. Then he took out a silk book from his sleeve and handed it to the maid and presented it in front of Li Yu.

"The geometry of the materials used to make the powerful gunpowder, and how to make it produce the power of opening mountains and cracking stones, are described in detail in the silk books. There are also three self-made fire thunderbolts with different charges, different sizes and different powers, and His Highness can learn from them. ”

Describing the silk book made of gunpowder and the fist-size, black iron lumps, Li Yu saw a little excitement in his eyes.

In ancient times, the ratio of potassium nitrate, sulfur and charcoal in the preparation of black powder was 15:2:3. However, Li Yu's description of the production ratio of black powder only stays in the description of the time travel novel he read in his previous life, and his impression is very vague, and he is not very clear about the specific ratio and what raw materials are needed, and he only remembers that the gunpowder must be granulated to make it exert its maximum power. No, after meeting Ge Jing unexpectedly and learning that he could make gunpowder, he was entrusted with this unreliable old task.

Clenched fist-sized iron bumps, the feel is still a little heavy, a lead is pierced out, the feeling of a primitive grenade.

"Then go to the school field and test the power of the fire and thunder!"

When the group arrived at the school field where Wang Fuxiu Yiwei was training, Li Yu had a trench five feet deep, three feet wide, and 15 feet long dug in the school field for the testers to lie down to avoid danger.

Then some chickens, ducks, geese, and pigs were tied with ropes and fixed in turn within a radius of three zhang to test the explosive power of fire and thunder.

Li Yu's strange behavior on the school field attracted a large number of curious maids and Xiuyi guards in the palace to stop and watch.

In order to prevent accidents, Li Yu called Xing'er and ordered her to take the left guard in Xiuyi to stop those curious maids thirty zhang away.

This test was of great significance, and Li Yu specially sent several close generals in Pyongyang, Xue Ne, Zhang Shi, Li Yesi, and others to watch.

Two clever guards were selected to stand in the trench dug in the school yard, and under Li Yu's nod, one of them held a fire thunder and lit the fuse, and the other person next to him was responsible for keeping an eye on him, in case he couldn't throw the fire thunder out and picked it up as quickly as he could.

After the fuse was ignited, the guards threw the fire and thunder in their hands among the livestock as fast as they could, and the two immediately lay down in the trench.

Thirty feet away, the beautiful maids gathered together whispered about what His Highness was doing in such a big battle in the school field today?

"Bang"

With a loud bang, it was like a thunderclap on the ground. The fire on the school yard flickered and a large amount of smoke and dust burst out, and then the neighing of pigs and the fluttering of undead chickens and ducks were heard.

The maids who were watching from the thirty feet were startled, and the flowers and branches trembled and attracted people's attention.

A pungent smell of sulfur came towards Li Yu and the crowd watching.

Ge Jing was very confident in the fire thunder he had developed, and his expression was natural. Now that the gunpowder recipe and fire thunder have been handed over, there is nothing to worry about. The affairs of the world are still to be worried about by the people who should be worried, and the people in my monastic path intervene in it to make jokes and talk in vain.

Li Yu couldn't wait to run to the school yard to check how powerful it was, only to see that all the livestock were dead within six feet, and all of them were injured within two feet, although the power was far less than the grenades in later generations, but it was enough in the world.

Li Yesi looked at the tragic situation of the livestock at the scene, and said with a moved expression: "This fire and thunder is so powerful, so isn't it an excellent weapon to defend the city in the future?" ”

"Nuo is an improvement, and you can also use trebuchets to throw them into enemy walls and military formations to inflict heavy damage on enemy troops." Xue Ne also agreed and put forward his own opinions.

Zhang Shihaha laughed and said: "Your Highness, when you immediately order the craftsmen to make thirty or fifty thousand, our Andong Army can immediately go south to destroy Silla." ”

How could Silla be able to destroy with a bullet with a new weapon?

Li Yu couldn't help but shake his head at Zhang Shi's nonsense, turned to Ge Jing and said: "The immortal master is Huaxia, and adds a sharp weapon to the survival of the Tang Dynasty, which will be remembered by future generations, and this king will thank you again!" ”

Ge Jing said abruptly: "Whether future generations remember it or not, Poor Dao doesn't care, I just hope that His Highness will make good use of this thing!" ”

……

"This matter is over, and the poor road will go!"

"Immortal Master ......"

Ge Jing refused Li Yu's retention, and left Pyongyang on the same day, saying that he wanted to have a good trip to the mountains and rivers of Andong!

Only Li Yu felt regret in his heart, but such strange people could not be used for themselves.
