In the period after that, envoys from other countries also came to Chang'an one after another. None of the emissaries of the Great Food Country, Japan, or Silla came to visit Li Shan.

However, the Turkic Don Valley came to Li Shan's mansion on the first day of arriving in Chang'an, but he came late at night, presumably to avoid people's eyes, and he did not give Li Shan very expensive gifts, but only asked Li Shan some questions about gunpowder very respectfully.

Before leaving, Dunyugu took out a scimitar from his waist and gave it to Li Shan, the knife was very short, only a foot long, as if it was a knife used by the Turks to cut meat. However, the scimitar has a wolf's head carved on it, which is lifelike.

Donyugu told Li Shan that this was a gift from Viga Khan to Li Shan, which meant that Li Shan would be an eternal friend of the Turks.

And the other who came to visit Li Shan was an envoy of Nanzhao. didn't say much, just a polite greeting, and gave Li Shan some souvenirs, which made Li Shan a little baffled.

When the envoys of various countries arrived, Tang Xuanzong was finally going to summon them, and Li Shan was ready to display the firearms.

Early in the morning, Li Shan put on his official uniform and came to Danfeng Gate, and hundreds of civil and military officials were also waiting here, and the envoys and ministers of various countries were all dressed in costumes.

The palace gate of Danfeng Gate slowly opened, and the eunuch said in a loud voice: "The emperor has a decree to order hundreds of civil and military officials and envoys from various countries to meet him." ”

On the royal bridge, the forbidden army was waiting in formation, and the eunuchs were also respectfully lined up on both sides, and the atmosphere was solemn and serious.

This is the day to meet foreign envoys, and the highest standard of honor guards are used, and the location is also selected in the Hanyuan Palace.

Entering the main hall, the emperor sat high on the dragon chair and looked at His Royal Highness's ministers.

Gamal, the envoy of the Great Food Country, stepped forward and said: "On behalf of King Yezid of the Great Food Country, Gamer, the envoy of the Great Food Country, has met with the emperor of the Tang Dynasty, and wishes that the two countries will always be close to each other, and hereby present a letter written by King Yezid." ”

Tang Xuanzong took the letter and took a cursory look at it and said: "I, Datang, accept your kindness, as long as you keep your own boundaries and don't act beyond the boundary." The Tang Dynasty would never face the Great Food Country. ”

Don Desire Valley also stepped forward and said: "The Turkic envoy Don Desire Valley on behalf of the Viga Khan visited the Tang Emperor and worshiped the Tang Dynasty Emperor as the Heavenly Khan, and wished the Turks and the Tang Dynasty to coexist in mutual benefit and get along amicably." Hereby offer tribute, here is a detailed list of tributes. ”

The Turks once called Li Shimin the Heavenly Khan during the period of Taizong of the Tang Dynasty, representing the Turkic submission to the Tang Dynasty, and with the increasing strength of the Tang Dynasty, the Turks also successively called Tang Gaozong, Wu Zetian, Tang Zhongzong, and Tang Ruizong as the Heavenly Khan.

Now it is natural to call Tang Xuanzong the Heavenly Khan.

Tang Xuanzong asked Gao Lishi to receive the detailed list of tributes.

Kim Ji-hyun, the envoy of Silla, said: "Kim Ji-hyun, the envoy of Silla, met with Xuanzong of the Tang Dynasty on behalf of King Seongdeok, and King Seongdeok was very concerned about the small grinding of the land boundary between the two countries because of the blurred land boundary before. This time, he sent a minister to discuss the matter. ”

Tang Xuanzong snorted coldly and said: "There is nothing to discuss in this matter, for the land of the Tang Dynasty, the Tang Dynasty will never give up an inch of land, as long as you give up the land, I can promise not to blame the past." ”

The Silla envoy didn't expect Tang Xuanzong to be so tough, and he didn't even give a chance to discuss in front of the public, so he had to retreat.

The Japanese envoy stepped forward and said: "The Japanese envoy Otomo Yamamori on behalf of the Japanese empress Emperor Motomasa met with the emperor of the Tang Dynasty. A detailed list of tributes is attached. ”

Tang Xuanzong said with a smile: "I have a lot of resources in the Tang Dynasty, and my culture has a long history and is broad and profound. Welcome visitors from afar to learn. However, if someone thinks that my Datang is weak and can be bullied, then it is an enemy of my Datang. ”

"Japan admires the culture of the Tang Dynasty and is willing to always be friendly with the Tang Dynasty and never be an enemy of the Tang Dynasty. ”

The envoys of Nanzhao also stepped forward and offered a detailed list of tributes. In the end, the remaining envoys of Tibet, as the defeated side, naturally had to lower their profile and present a letter of surrender. And read out the meaning of the reparations for the defeat already in the article.

In the end, Tang Xuanzong ordered someone to issue an edict, which was nothing more than that Tubo and the Tang Dynasty had always been good friends, and this dispute would not affect the friendly relations between the two countries. And marry a certain princess to Zampu to show the friendship between the two countries.

The Tang Dynasty has never been a genuine princess, at most she is a clan girl, and she will marry if she is temporarily given the title of a princess.

In the end, after all the countries worshipped, Tang Xuanzong began to make a big show, inviting all the envoys to visit the military parade of the Tang army.

One of the main purposes of the envoys from various countries is also to see the power of firearms, and Tang Xuanzong naturally wants to take this opportunity to deter these countries and let them know how powerful my Tang Dynasty is.

This time, Li Shan also made all preparations, although the artillery was not successfully developed, but Li Shan still thought of a way. After reporting to Tang Xuanzong, Tang Xuanzong also felt that Li Shan's method was feasible, so he agreed to Li Shan's strategy.

The envoys of various countries came to the military camp on the outskirts of Chang'an,

Li Shan stepped forward and said: "Li Shan, the secretary of the minister's arms department, enlighten the emperor, all the firearms have been prepared, please give the emperor an order." ”

Tang Xuanzong waved his hand and said, "The review begins." ”

Now the army has gradually begun to learn Shen Shixing's training methods. Moreover, Shen Shixing has also been promoted to one of the sixteen guards of the capital because of his meritorious service in the battle of Liangzhou and his good military training.

The Tang army was neatly organized, the dispatch was orderly, and the whole style was completely new, which amazed the envoys of various countries. It's just that very few people know that Shen Shixing's method of training the army was learned from Li Shan.

The demonstrations of rockets, trebuchets, and thunderbolts made the jaws of the envoys of various countries almost drop, and the prince of Tubo had a gloomy face and whispered to his subordinates who didn't know what he was saying.

"Next, please take a serious look at the envoys, my Datang's latest weapon, the Shenwu General Cannon." Li Shan gestured, and a soldier pushed a huge gun cart to the center of the field.

"The power of this military cannon is huge, and it is the latest firearm developed by my Datang, and it has not yet been officially put into use. The gun has a range of more than 800 meters and can penetrate a one-foot-thick door panel. ”

For the demonstration, a huge wooden target was set up from 800 meters, and the gun was pushed to the fort, and the design of the gun was still in shape, with a barrel, a gun chamber, a bracket, a wheel, and a crosshair on it.

But only Li Shan and Tang Xuanzong knew that this thing was just an ornament.

Li Shan quietly glanced at Tang Xuanzong, and when he saw Tang Xuanzong's inquiring gaze, he made a proper gesture at Tang Xuanzong.

"Ignition." Li Shan gave an order, the red flag here was raised, the artillery ignited the fuse, and with a bang, the target 800 meters away was immediately blown into pieces. The envoys of various countries all gasped, such range and power were beyond the scope of confrontation.

Their strong bows and crossbows, trebuchets, although not as powerful as firearms, still have the ability to fight against rockets and trebuchets, after all, both sides hit each other.

But for artillery, whether it is the enemy's attack or our attack, it is someone who hits you, and you can't hit someone, which is very embarrassing. It has gone beyond the scope of confrontation and has become a one-sided torture.

Just two days ago, Tang Xuanzong made a special trip to summon Li Shan, because the Shenwu General Cannon had not yet been developed, so Li Shan did not join this matter when he reported the review ceremony.

However, in order to enhance the deterrence of this military exercise, Tang Xuanzong wanted Li Shan to show the general artillery in this military exercise.

Li Shan already had a general idea of the production of artillery, which was all in his head, but he didn't want to expose it like this. Because he still wanted to use this excuse to find Long Xueling. But it's pretty straightforward to show it.

"Your Majesty, in fact, there is a method that can still be tried. We only need to hide a thunderbolt on the target, and then fire an empty cartridge on the artillery, as long as the timing is adjusted, the effect of the artillery can be achieved. ”

When Tang Xuanzong heard it, he felt that it was feasible, so he asked Li Shan to direct such a play. (To be continued.) )
