Emperor of the Tang Dynasty

However, for the current situation, the four generals can only hold back.

Because this scene is similar to the previous time when His Royal Highness the Crown Prince researched how cement and concrete are similar to Mo Dao and Sanleng Army stabbing, they were suddenly unable to find anyone, and they didn't dare to disturb Li You at all! .

Chapter 815 Epoch-making

After all, the similar situation shows that His Royal Highness is holding back his big move again!

And at such a time, if he hastily disturbed His Royal Highness, what would it be?

Thinking back to the big moves that His Highness the Prince had made a few times before, they all gave them a huge surprise. Li Xiaogong and others kept reminding themselves in their minds that they had to hold back, they had to hold back.

Anyway, when His Royal Highness the Prince is pointing the way, he can also send someone to pass a note to them, which is not in the way at all.

As the four generals thought, Li You is indeed busy developing new weapons now.

In other words, he had thought of this weapon a long time ago, but he had no time to build this large-scale weapon because he was making the Mo Dao and the Three-Edged Army Thorn.

"Crack! "Three Twenty""

Right behind the army, Li You took the drawings in front of a group of craftsmen brought by Songzhou.

"Your Highness, is this...?"

The head of the craftsman asked suspiciously. After going through the previous process of manufacturing the Mo Dao and the San-Ling Army Thorn, they did not dare to underestimate this Highness even in the professional field.

After all, who would have imagined that the dignified Crown Prince would actually appear more professional than them all in this regard?

"The weapon made by this blueprint is called the three-bow crossbow. You can also call it the eight-bow crossbow. It is mainly used to siege cities." Li You explained.

That's right, it is precisely because these three-bow crossbows are mainly used to siege cities, which are epoch-making siege weapons, so Li You put it behind the Modao and the Sanleng Army thorn.

In the previous attack on Nyingchi City, Li You expected that Songtsan Gampo and the others would not stick to Nyingchi City, so in this case, there was no urgent need for powerful siege weapons.

However, after leaving Nyingchi City, the situation was different.

Songtsan Gampo and Lu Dongzan will eventually lead the army and arrive at the capital of Tubo, Luase City. Now that they have already arrived at Luose City, the rest of the Tubo army is of course defending the capital!

After all, they can no longer retreat, and there is no need to rush back.

At this time, it was the turn of the big killer of the three-bow crossbow to shine!

"Three-bow crossbow?"

Hearing what Li You said, the craftsman leader and several main craftsmen gathered around curiously and studied the blueprint of the three-bow crossbow carefully.

The arrows of the three-bow bed crossbow are made of hard wood as the arrow shaft and iron as the feathers. It is called "one gun, three swords and arrows" and the three-bow bed crossbow can also fire "treading arrows", which is spectacular when fired. .

Those arrows are like javelins, and they can be directly nailed into the city wall when fired at close range. When firing salvos, rows of arrows are firmly nailed into the city wall, and the siege soldiers can even climb up by this!

Originally, the three-bow crossbow only appeared in the Song Dynasty and gradually developed to its peak. Li You directly took out the perfect version of the three-bow crossbow in advance.

"This... it seems that the principle is not complicated, but the effect is amazing!"

After watching for a while, several craftsmen exclaimed in unison.

With their knowledge, it is natural to see that the three-bow crossbow is not difficult to achieve, and with their experience, they can immediately imagine how powerful and terrifying the three-bow crossbow will be after it is completed!

"His Royal Highness, did you design and invent this weapon?" the craftsman leader asked excitedly, "Its terrifying power and exquisite structure are definitely a work of genius!"

No wonder they are so excited. After all, these three crossbows are equivalent to the design of the future spanning hundreds of years. It is definitely an epoch-making invention!

Li You shrugged noncommittally, and said, "Okay, if you have time to talk here, why don't you hurry up and build it! If you want to play the most perfect siege effect, you need a lot of numbers."

"Yes! Caomin will mobilize everyone!"

……

When Li You was making three crossbows, Tang Jun also fought against the Tubo army countless times.

Under such a situation of fighting and retreating, Songtsen Gampo and Lu Dongzan finally got out of the way, and they saw the shadow of the city in the distance!

"Finally... it's finally here!"

Even Lu Dongzan almost burst into tears when he saw the shadow of Luoseicheng...

Along the way, they were suffering from sin and torture all the time, everyone was exhausted, and the price paid for it was extremely heavy.

As Li You speculated at the beginning, in fact, the total force currently possessed by Tubo is about [-] people. After Songtsan Gampo took [-] people from Songzhou, there are only [-] remaining in Tubo. Soldiers and horses are not enough to suppress the chaos.

However, Songtsen Gampo really wanted to bring reinforcements back to send more manpower, and he actually tried his best to do so, but he always killed Li You along the way!

All the way down, the Tubo army was at a disadvantage all the way, plus the losses on the Songzhou side, the Tubo has now suffered a full [-] casualties!

On the other hand, according to the visual estimates of Songtsan Gampo and Lu Dongzan, there were only about [-] or [-] casualties. This ten-fold difference in casualties was simply engraved in the depths of their souls. The greatest shame!

The worst thing is that there are only more than [-] Songtsen Gampo left who can be mobilized. How can they support the domestic suppression of chaos?

It is true that Songtsen Gampo had to send more manpower, otherwise it would be meaningless for him to come back in time for 2.4. But after sending manpower, how many people would they have left to deal with Tang Jun?

If you want to completely fill the vacant force, at least [-] more troops must be sent out, right?In this way, there may only be hundreds of thousands of people left to fight in the cities!

"Damn! Where did their supplies come from? Why does it seem to be infinite!?"

As long as he thinks of this, Songtsen Gampo's liver hurts with anger.

Fortunately, everything has now become history, and they have successfully returned to the city!

"Let's go! Let's enter the city!" Songtsen Gampo took a deep breath, "With the power of the city, I must make that Li You look good this time!"
