The current Datang Shenwei Cannon, no, has become the Datang Shenwei Cannon version 1.0 in Li Tai's mouth.

The firing range is about 300 meters, and it takes about five minutes to fire a shot due to the cooling of the barrel when loaded.

In fact, at the beginning, Tang Ping didn't think about letting them directly engage in the Fran machine gun.

The so-called Furlong cannon is a rear-loading gun that can be disassembled.

The charge is like a jar, and then the jar can be installed in the back half of the cannon, and after a shot, the jar is taken out and replaced with a new canister.

In this way, whether it is reloading or cooling, the speed can be greatly increased.

And the mobility is also better, but later, considering the forging ability of Datang, now to make the Furlong cannon, if the airtightness is not good, it is better to do this kind of front-loading gun.

After all, the best opponent of the Fran cannon is also the cavalry rather than the city wall, and if it is really a blow to the city wall, it has to be more powerful than this front-loading gun.

However, now this experimental base can no longer be used, firstly, Tang Ping's opinion is very large, and the experimental artillery here has seriously affected Shanghe Village.

Postpartum care for sows is not easy to do.

Second, it is not far from here to Xiahe Village, and there will be more and more people at that time, and it will be easy to mix in as soon as there are more people.

So it's better to find a more closed and remote place.

In this way, when Li Shimin left, he took Li Tai back, saying that the eldest grandson hadn't seen this fat son for many days, and he had to take it back to show the eldest grandson.

Then soon this year's spring festival ended, although these students were given a turn by Li Bai before the spring festival.

But I have to say that in the end, the students who stayed to participate in the Spring Festival basically had real talents, and through the literary meeting with Li Bai, their studies were still improved.

So in the end, although there are fewer people, it is not unacceptable.

Then Chang'an ushered in batches of guests.

Because Tang Ping and Wang Qingluan's wedding is coming.

This time, it was both Datang and Dongyue who posted, one is the country with the strongest military strength, and the other is the country with the strongest economic strength.

The other neighboring countries naturally wanted to save face, so soon one team after another

The envoy group came to Chang'an.

Northern Yan, Turkic, Tubo, Tuyuhun, Goguryeo, Buyeo, Fusang, Dongyue, Ximan, and more than a dozen small countries in the south came.

Everywhere in Chang'an City, you can see outsiders in strange costumes.

The most low-key estimates are the Turks and the East Vietnamese.

Because the Turks are now the Shu Kingdom of the Tang Dynasty, and Gu Xiaotang used the excuse that the Turks had only experienced a big war, there was really nothing good, so he only sent a shabby ten-person envoy group.

And Dongyue is because of the ambiguous relationship between Wang Qingluan and Dongyue, although nominally she is still the princess of Dongyue, and this time she is married to the Tang Dynasty, but now Dongyue is Zhen Xiong, and he knows that the contradiction between himself and Wang Qingluan is impossible to reconcile.

So he sent an envoy group, that is, to save face, what he needed was the support of Datang.

This time, the East Vietnamese envoys were not so much here to send congratulatory gifts, but to see if there was any change in Datang's attitude or strategy towards East Vietnam.

Now that Dongyue has built several new seagoing vessels through Tang Ping's drawings, they are still very dependent on the export of tung oil from the Tang Dynasty.

Only a new-scale navy can enable the East Vietnamese, which is close to the sea in the east, to open up overseas markets and thus obtain a larger economy and equal resources.

After all, there is too little steel produced in East Vietnam, and almost all the countries on this continent have iron that is not for sale, so they can only go overseas to find enough iron to strengthen their military strength.

So they can't let Wang Qingluan affect the relationship between the Tang Dynasty and Dongyue.

"Childe, some Turks are looking for you, saying that you owe them something!"

Tang Ping, who was wandering around the village, suddenly received a call from Xiaoluo.

"I owe them something?" Tang Ping was a little unsure, but since he was from the Turks, he should go and have a look.

When I returned to the convenience store, I saw a big man standing at the gate of his courtyard.

"Begging!" This is also an old friend, when he was in the Turks, Qihuli was chased and killed by other Turks, and he was rescued by Tang Ping, and then they were not separated until Tang Ping and they returned to Chang'an.

"Yin Shanhou, hello!" Qihuli came up enthusiastically and hugged Tang Ping: "It's been a long time!" ”

"Yes!

Tang Ping nodded, although it had only been a few months in fact, but when he suddenly saw Qihuli, he really felt that it had been a long time since he left him to go to the Turks.

"How? Are you in the Turks now? Tang Ping looked left and right, and said in a low voice: "Hou Junji is not embarrassed for you, right?" ”

He knew that Hou Junji was a greedy person, and it was not a good thing, so he sent Hou Junji to the Turkic side to manage the capital and protect the palace, and there was nothing else, he was afraid that Hou Junji and his Turkic friends would not get along.

"Nope!" "Actually, we haven't seen him much, and I heard that he drinks in the Metropolitan Protectorate most of the time, and he probably doesn't like the bitter place of our Turks." Now everyone is doing well, and many of our people who were separated at that time have returned. ”

"And what about you Great Khan?" Tang Ping asked.

"Great Khan...... It's also pretty good, but I've recently been pregnant and don't have much appetite. ”

Tang Ping was stunned for a moment, then looked at Qihuli and asked, "Pregnant?" Gu Xiaotang is married? ”

I asked what I meant, and then I reacted before I changed my words and said, "You Khan are married?" ”

Beggar shook his head and said, "I didn't get married." ”

Tang Ping didn't know what to say, after all, this was someone's business, so he patted the beggar on the shoulder and asked, "Okay, I also said that I would go to Chang'an tomorrow to see who the Turkic mission is, since you are here today, I will let you taste our good wine here!" ”

Qihuli nodded, then took out a piece of paper from his arms and handed it to Tang Ping: "This is the Great Khan who said that you owe her, and asked you to return everything to him this time." ”

Tang Ping opened the note, on which was his own handwriting, an IOU written by himself to hire Gu Xiaotang, and then learn to ride.

It adds up to a total of more than 60 pieces of chocolate, but I didn't expect Gu Xiaotang to be a mother, and she specially called someone to come and ask for chocolate.

Looking at the contents of the note, Tang Ping actually had a different feeling in his heart, and he couldn't explain it clearly.

Carefully folded the note again and slapped it in the palm of the beggar hand.

"Don't you just want to eat chocolate? You don't need her to bring an IOU, I'll bring you a box when you go back. As for this IOU, next time I will ask her to change it herself! ”
