It is a huge mountain cave.

Traces of explosives can also be seen on the rock walls, which were left by the blasting carried out during the mining of the cave.

There are many pores in this huge cave, and there is a glass-paved skylight on the top, so the lighting is also excellent.

Many members of the urban management team were already stunned when they looked at the busy scene in the cave.

I saw hundreds of people dressed in strange white costumes busy in the mountain, huge iron tools, all kinds of metallic objects, as if everyone entered another world.

Biao Daguang straightened his special uniform, and said to Xu Yang in a happy tone: "Master Hou, according to your instructions, since you went overseas, the progress of the Guigu Research Institute has not stopped for a moment, and now according to the information you gave, Zheng Wen is leading the team in the real room to carry out the final processing and manufacturing of the pistol, and I heard Mr. Meng, who is in charge of the manufacture of precision instruments, say that the first sample of this pistol will come out soon." ”

Xu Yang looked at Biao Daguang, with a satisfied smile on his face, and patted him on the shoulder, "Hard work, Daguang." ”

"Hehe, it's not hard." Biao Daguang touched his bald head embarrassedly, as if he remembered something, and sighed in a tone, "Master Hou, the members of the original Flying Tigers plus the newly recruited heroes of the rivers and lakes are now twenty-three people left, and the elimination rate of training is really too high." ”

Xu Yang's eyes also flashed, and he nodded lightly: "There are not many soldiers, but they are fine, what about the remaining hundred or so people?" ”

Biao Daguang's tone was a little declining, and he said: "According to Master Hou's instructions, they are not qualified to continue special training now, so I directly arranged them to be guards in the real room, and for the sake of secrecy, I didn't let them out." ”

"Hmm" Xu Yang nodded slowly, "Next time they don't have to continue to be guards here, there is a team of Flying Tigers here, wait for them to join this team." ”

Biao Daguang's eyes lit up, and he said gratefully: "The last general will obey the order." ”

Xu Yang glanced at the huge mountain a few times, and said with satisfaction: "Take me here for a casual walk, I haven't been here for more than half a year, and I don't know if the things I explained to Zheng Wen have been done." ”

"No!"

In the huge caves, there are small caves one after another, and inside them are one real yàn room after another.

"Assistant, assistant! Bring me my pliers. A young man with some yellow hair and a white real yàn suit held a book in his hand, and stood next to the real yàn instrument in a small cave without raising his head and shouted something.

A plier was handed to him, and Zheng Wen frowned and muttered, "Why is it so slow." Then he stopped talking, and began to twist with his pliers a strange iron object on the table, which was the flintlock striker of a pistol.

"My hair is a little yellow, which is a symptom of lack of sun exposure and iron deficiency in the body." A voice suddenly came to Zheng Wen's ears.

The movements in his hands suddenly stopped, Zheng Wen slowly turned his head, and saw Xu Yang looking at him with a smile.

"Master Hou!"

Xu Yang's sudden return made the researchers in the entire real room enthusiastic, and the cult of personality had reached the point of no increase among the people at this time, for no other reason, the more science went up, the more they would find their ignorance and lack of knowledge, and the higher they went, the more they would find out how profound the scientific books Xu Yang gave them were, enough to destroy the world.

Therefore, all the researchers in the real room, whether they were Taoist priests recruited from those Taoist temples in Youzhou, craftsmen from Youzhou, or professionals from all walks of life recruited from Chang'an, they all regarded the books that Xu Yang gave them as treasures.

At the same time, the things that Xu Yang ordered them to study were also the same thing that they suddenly felt that their value was so great.

"Master Hou, would you like to see the results of our research?" Zheng Wen looked at Xu Yang with excitement on his face, he was the first batch of old people to follow the Ghost Valley, so he was the first to speak.

"Okay, turn out all your research results and show me, the research is good, and this marquis will be rewarded." Xu Yang said with a smile, he didn't have the slightest timidity standing in front of everyone now, but had a special aura, as if he should have been the protagonist among these people.

"Hehe, then you're welcome, everyone, I'll come first." Zheng Wen smiled and trotted all the way to his real room, opened a small cellar, and took out a small wooden box from it.

Looking at Zheng Wen who was trotting all the way, Xu Yang was also full of smiles, "What treasure is hidden so deeply?" ”

"Master Hou, you will know it at a glance." Zheng Wen said with a smile.

Slowly opening the small wooden box, Xu Yang glanced at it with a smile, but he was almost so frightened that he threw the wooden box in his hand.

"Grenades?!"

"Exactly, Master Hou, is this a surprise?" Zheng Wen's mouth was almost grinning to the root of his ears.

Xu Yang's heart has already been flooded with turbulent waves, and even the super killer weapon of the grenade has been made out, in this world, who else can stop the footsteps of Datang? Now he just wants to ask, who else?

Holding Zheng Wen's hand, Xu Yang said with a straight face: "How much is this grenade?" ”

Seeing Xu Yang's stern face, Zheng Wen also replied respectfully: "Back to Hou Ye, this kind of thing about gunpowder is not very stable, so we didn't dare to make it in large quantities, and only made about five hundred pieces, which were placed in a damp cave far away from the real room, but if Hou Ye needs it, this kind of wire-drawn grenade Our craftsmen can make a large number of them, as long as the gunpowder is sufficient, five hundred pieces a day is more than enough." ”

When Xu Yang heard this, his face was overjoyed, and he waved his hand, "From tomorrow, the whole line will start work, and you can make as many grenades as you can!" "Xu Yang has already begun to fantasize about standing on the city of Silla and throwing grenades at the soldiers besieging the city below, this kind of lethality, tens of thousands of grenades thrown out, the Goryeo stick will definitely pay the price of blood!

When Zheng Wen heard this, he was also curious, "Master Hou, are we going to fight in the Tang Dynasty?" ”

"Hmm." Xu Yang nodded, "Goryeo united with Baekje and Wa to form an alliance, the main alliance of the lord of Asia, planning to attack Silla, the queen of Silla is still in the palace to ask Her Majesty Xià to send troops to aid Silla, the expeditionary force of the Tang Dynasty will probably be able to fight to Silla soon." ”

Everyone was indignant when they heard it, after all, this Goryeo had invaded the Central Plains many times, and the Sui Dynasty sent 100,000 good men from the Central Plains to conquer Goryeo, but they were all slaughtered.

"Master Hou, since it is an attack on Goryeo, the firearms invented by our craftsman department will definitely be able to show their skills!" Zheng Wen's face flushed a little from excitement.

"Oh? What firearms? Xu Yang asked curiously.

"It is an improved version of the flintlock musket, there are long guns and short guns, the long guns were invented a long time ago, but they are easy to jam, and the starting range is not long enough, according to the deeper drawings we found that as long as the starting device and the length of the gun body are slightly improved, as well as the shape of the bullet, we can get a longer range and more powerful firearms!" The foaming stars in Zheng Wen's mouth were about to squirt out.

"Quickly bring the improved firearm to this marquis!" Xu Yang also said in surprise

Mobei, an endless grassland.

Jieli Khan looked at the cattle and sheep grazing in front of him with satisfaction, and spent this year's winter, the Turks are steadily recovering in strength, but when he looked in the direction of Youzhou, his face became a little gloomy, his nephew Tuli Khan has always had a relationship with the Tang Dynasty, and Li Shimin of the Tang Dynasty has a very good personal relationship, and now he is even more worshipful of Youzhou culture, often disguised and dressed up to go to Youzhou to play, which is a shame for the arrogant Turks, but he is happy to do it.

With a cold snort, the Khan of Jieli planned to wait for another two years to come to Chang'an and earn a vote to go back.

"Khan, I heard that the queen of Silla is asking for help in Chang'an, and the Tang Dynasty wants to send troops to Silla to fight against the three-kingdom alliance of Goryeo, Baekje, and Wa, this is simply a godsend, and after this year's cold winter, my Turks can take the opportunity to send troops to the Tang Dynasty, and then go to Chang'an to plunder!" A priest with a pattern on his face said with a wicked smile.

"The building of Moda is very much in line with the Khan's wishes." The corners of Jie Li Khan's mouth also showed a cold smile R1152
