Datang: Destroy Tang Taizong Li Xiao at the beginning

Lantian Villa, in the study.

"Your Highness!"

At this time, Li Junxian was reporting the internal situation of the villa to Li Xiao.

"Two red cannons have been cast, and the inventory of other weapons and equipment has increased by about [-]%."

"According to the drawings provided by His Highness, high-explosive grenades, smoke bombs, tear gas bombs and other throwing weapons have also been successfully developed, but due to insufficient materials, the total number is less than a hundred."

"There is also a land tank, and one has also been built. Would you like to have a look at it, Your Highness?"

"Created?"

Li Xiao was a little surprised.

Speaking of this land tank, it is a vehicle-mounted weapon designed by him for war based on the tank model of later generations.

It is specially used to counter the Turkic cavalry charge.

Although the defensive strength of the villa is enough.

But you can't be locked inside and be beaten.

As long as people besiege and don't attack, they will cut off your food and grass, and the game will end directly.

Therefore, after the construction of the city defense was completed, Li Xiao began to prepare to build an army that could rush out and kill all directions.

And the core is this land tank.

"Go, go and see!"

Li Xiao got up and couldn't wait to walk in the direction of the craftsman's workshop.

At this time, a guard came over and whispered something in Li Junxian's ear.

After Li Junxian heard this, his face suddenly changed.

"what happened?"

Li Xiao was puzzled.

"Your Highness, the national war has broken out!"

Li Junxian looked solemn: "The news just came that the Turkic army went south a few days ago and rushed to attack Youzhou. The battle situation is not optimistic!"

Chapter 250: Land Chariot

"The Turkic army invaded the country?" Li Xiao frowned, "Why is the capital still peaceful and peaceful?"

"Perhaps the news has just arrived, and it hasn't had time to spread." Li Junxian said in a deep voice.

Li Xiao shook his head slightly: "Probably not, the imperial court should have received the news earlier than us. It is estimated that the situation is extremely urgent. In order not to shake the hearts of the people, everything was temporarily covered up."

Speaking of this, Li Xiao suddenly remembered Li Er's expression in the imperial study.

The outbreak of war is urgent.

And then there was the paddock assassination.

He didn't need to guess to feel the anxiety in Li Er's heart.

Compared with Li Er, Li Xiao's heart is heavier.

Historically, when the Turks went south this time, they would fight all the way to Chang'an, and then there was the Weishui alliance.

But now, many things have changed.

In addition to the Turks, Japan also joined the war.

Datang has almost no chance of winning.

And he, although he knew the result a long time ago.

Also working hard to prepare for this.

But after all, the development time is too short.

With his current strength, it is simply not enough to sweep Turks and Japan.

It can only guarantee that Lantian Villa will not be breached.

Of course, he had thought of this a long time ago, so he designed the land tank.

Thinking of this, Li Xiao hurried to the artisan workshop.

In the yard, a chariot with a dark body and a cold light was parked there.

"Your Highness!"

Seeing Li Xiao coming, several blacksmiths and craftsmen who had been waiting here for a long time saluted together.

"According to your order, the core skeleton of the land tank is made of iron wood."

The chief blacksmith began the introduction.

"The outer layer of the chariot is a heavy-duty alloy exoskeleton device, and the wheels are made of special rubber, which has good wear resistance."

"Ahead, here are the two longest spikes, which can effectively resist the charge of the enemy's horses."

"Except for the exit above the chariot, there are these barbed spikes all around."

……

Li Xiao knows best about the chariot designed by himself.

Due to the failure to solve the power, manpower is still used to move the chariot.

The principle is to learn from the pedal braking mode of bicycles.

But on its basis, a little improvement.

The chariot is divided into two parts.

At the front of the car, there is one person in the main driver's seat.

The rear of the vehicle, which is the main body of the chariot, has four positions for power supply.

The outlet of the main carriage, borrowing from the tank, is arranged above the carriage.

The exit can be equipped with two soldiers who handle weapons.

Outside the entrance and exit, there are two reinforced crossbows.

In the middle, it is also equipped with a reduced version of the artillery.

Because normal-sized cannons are too heavy, the only option is to use small cannons instead.

In order to preserve the agility of the chariot, we had to give up firepower.

This is also impossible.

In Li Xiao's view, this chariot looks like a combination of a tractor and a tank.

"This this……"

Zhao Yuntian looked at the huge iron lump in front of him, hesitant to speak.

"Your Highness, can this be pushed?"

Li Junxian expressed what was in his heart for Zhao Yuntian.

On the side, Lu Li, Xue Rengui, and Wang Qingxue also had weird faces.

Even if they know that Li Xiao likes to research some strange things.

"More than half of the material used to build a land tank is steel, and its weight is between [-] and [-] jins. With such a weight, it may be difficult to move an inch," Lu Li said thoughtfully.

"Push? Hehe..." Li Xiao was immediately happy when he heard the words, "If I can't move, what's the use of it?"

"Let me try!"

Zhao Yuntian rolled up his sleeves and came to the back of the chariot.

He gritted his teeth and pulled all his strength, so the veins on his forehead popped out.

But after working hard for a long time, the chariot still stopped in place without moving a bit.

"A reckless man." Li Xiao was speechless, "Not all cars need to be pushed!"

"Step aside!"

"Is Your Highness going to perform it again?"

Li Junxian couldn't help flashing a trace of expectation in his eyes.

Obviously, Li Xiao was full of confidence.

In other words, this chariot can move completely.

As for what method to use, they don't know.

"Old Zhao, Uncle Li, Xue Rengui, Lu Li, you four climb in through the upper entrance."

Li Xiao rolled the rolls one by one.

The four immediately followed suit.

The space inside is very small, only six people can be accommodated.

Under Li Xiao's guidance, the four of them found a seat and sat down.

"There's a pedal under the seat, see that?"

Li Xiao continued to command: "Step forward!"

At the same time, Li Xiao also climbed into the front cockpit.

Braking is done entirely by human pedaling, and then the chain and gears are connected from the inside, so in the cockpit, only need to turn the steering wheel to change the direction of the wheels.

Following Li Xiao's order, Li Junxian and the other four stomped down hard.

In an instant, under Wang Qingxue's shocked gaze, the land chariot actually moved.

And still rushed forward at an extremely fast speed.

Li Xiao also didn't expect the four of them to be so strong. Seeing that they were about to hit the wall, he immediately turned around.

But still a step too late.

The two long spikes in front of the chariot pierced into the wall in an instant.

The chariot stopped abruptly.

"It actually moved!"

Zhao Yuntian who was sitting in the chariot looked shocked: "And the speed is so fast!"

Beside him, Lu Li had a puzzled look on his face, "What is the reason why the chariot can move forward by stepping on such a small thing?"

"What I care about is..." Li Junxian's eyes were full of confusion, "Such a heavy chariot, logically speaking, it would take a lot of strength to move it, but..."

"Yes!" Zhao Yuntian continued, "I hardly exerted much force just now."

"If you can understand it, it's outrageous!"

Li Xiao came out from the cockpit with a smile on his face.

The performance of this chariot is not bad.

Extremely fast and very lethal.

It will have an unexpected effect when used in flat push flow tactics.

The disadvantage is that the steering is a bit slow and needs to be improved.

"Your Highness, what is going on? How did the chariot move?"

Lu Li was the first to climb out, his face full of doubts.

Li Xiao said with a smile: "Pedaling adopts an ergonomic design concept, and the rest also uses the principle of leverage and poor gear transmission ratio...you can't understand it."

"In short, it's very complicated. You just need to know that you can generate power by stepping on the pedal."

Hearing this, several people immediately looked at each other with wry smiles on their faces.

In Li Xiao's place, even if they saw it with their own eyes, they would not be able to understand any point of knowledge.
