"Put on a horse and test it to see if it rolls over if it gets into a hard stone." Li Dedao.

The carriage is also easy to overturn after hitting something, and the Turks have obviously used the bearing of the constitution as the key to the finale, using their own weight to avoid overturning when impacting.

But then the speed decreases, and the number of horses needed increases, but in this way, the horses run without the arms extending from the bearings of the rooks, and the armor is enough to make it difficult for the opponent to parry.

Since the Turks have developed this kind of thing, they have to guard against it.

Li De was also afraid that the vanguard soldiers who went out on the expedition would suffer, so he wanted to study a way to crack it as soon as possible.

The Lu brothers prepared a number of stones, forage and other obstacles in the open field, and after the chariot was ready, let the heavily armed warriors drive the chariot to rampage through the field.

After a while, the venue was in shambles, and those stones were all shattered after impact, and the power was terrifying, and it was definitely a sharp weapon for charging into battle.

"What an amazing impact, is this the chariot of a hundred years ago?" Li Shimin exclaimed.

Li Shimin is well-read and still knows a little, but the ancient chariots are no longer suitable for the battlefield, and he didn't expect the Turks to use this chariot tactic again.

In this way, the destructive power and importance of the chariot have not diminished at all, and the speed of the cavalry alone cannot be bargained for in a melee.

Li De observed that the damage of the chariot is not to see a stone or to rush into it, but to rely on the driver's consciousness and the strong bearing to inflict powerful damage.

The disadvantage is not nothing, the chariot is very heavy, even if there are two horses the speed can not catch up with the cavalry, but it is precisely because of this that the chariot is not easy to overturn when it hits.

If this chariot is applied to the charging battle, it is definitely a nightmare for the infantry, through the description of Cheng Zhijie and You Junda, Xue Liang was in charge of the pursuit of 2,000 people at that time, which is counted as 30% of the combat effectiveness.

Even Wei Chigong's men were lost as much as 10%, which shows that the power of these chariots is very suitable for fighting with life and death, and the Turks have been planning to enter the hinterland of the Sui State for a long time.

"Governor, do we want to make this chariot?" The Lu brothers asked questions.

Li De was thinking about things, but was interrupted by the other party's voice, reacted, and asked: "Of course, but you can't just do it, since it is a chariot, you have to play more roles." ”

Li De picked up the pen as he spoke, widening the size of the chariot, since the impact depends on the inertia after the speed rises, it is better to make the chariot bigger and have more horses, anyway, it is prepared for the charge.

In order to avoid getting the chariot into a melee and being especially taught by the enemy, then in terms of tactics, it is necessary to pay attention to rampage, like a vanguard and a horse to rush directly to the end.

But how to ensure the lethality of the enemy in this way, this is where Li De wants to improve, since the bearing can be extended, why can't the weapons on the field be installed with something powerful.

For example, the oil car, such as the cluster bow and ballista used on the city wall of Youzhou City, can resist the arrows of the previous bow and arrow team in one salvo.

If these things are installed on combat vehicles, then they are an absolute killer.

"Yes, that's it." Li De was holding a brush and was in a daze on the table, and what everyone saw on the side was Li De smirking there alone.

Don't know what's going on.

"Brother-in-law, are you alright?" Li Shimin asked softly when he saw it.

"Oh, nothing, I just came up with something good, I'll draw it for you to see."

After Li De finished speaking, he began to draw, there was a big box on the chariot, and everyone saw the weird, and then he talked about the picture inside, in fact, there were water spray trucks in ancient times, spraying water.

They are all simple pressure devices made of lever principles, used to extinguish fires, but the era of emergence is later than now, Li De painted the installation of spray trains on the chariot, the principle is very simple is to fill the box with oil, and then use a similar pressure to ensure the attack range of the oil.

The flame is not burning on the inside, but on the outside, as long as you do a good job to prevent backfire, as for the internal structure, it is pressurized by using skin pockets and various gas empty pockets.

It took him a long time to draw it, and it took several sheets of paper, each of which was marked with details of the overall and internal analysis.

"Brother-in-law, can this thing breathe fire?" Li Shimin asked suspiciously.

This kind of super bold thing, anyone will be surprised when they see it, and the Lu family brothers on the side will directly enter the state of discussing technology when they see this thing, and others can't understand what they say at all.

Li De finished drawing the drawings, and whether it can be realized or not depends on the Lu brothers to make it.

"Of course you can, you see that there is a fire guide outside, as long as the principle of compressed air is used to make the fire oil spray out, and the pressurization only needs two people in front of the chariot, and two more drivers can achieve it."

Li De began to explain that the fire outlet of the oil cart was at the back of the car, and there were three ports on the left and right sides and three at the back, which could ensure that as long as the carriage moved forward, it would not be affected by the oil oil.

The explanation is very detailed, the tactics have been thought out, in order to ensure that the oil truck ensures maximum lethality, there will be a pair of cavalry in front of them to open the way, and the route taken is to move forward.

"Brother-in-law, if this oil truck really succeeds, it will be a nightmare for the enemy." Li Shimin said in surprise.

Li Shimin is really very interested in this new weapon, and once it is used, it will definitely be able to gain the upper hand.

Before it was over, Li De began to draw again, this time it was easy for people to understand, and directly drew a bow and crossbow cart on the chariot, and a bow and crossbow team worthy of one or thirty people on the chariot.

The point is that this ballista can be moved at any time, if there are a hundred or ten such chariots, then with the excellent killing range of the arcista, it is definitely a sharp weapon on the battlefield, and its role is even more important than the Spitfire chariot.

Li Shimin watched from the side, thinking that if he was really equipped with hundreds of such fast bow and crossbow carts, he could not only continue to load arrows, but also be able to carry supplies for soldiers and horses, and he would simply have a logistics army with strong combat effectiveness.

He imagined that in front of the array of millions of soldiers and horses, tens of thousands of arrows flew through the sky with a single wave, and that scene seemed to have the momentum of a million Qin soldiers destroying the Six Kingdoms.

When Li De designed this mobile bow cart, he considered it to be a cluster battle, so the angle of all the bow carts was heightened and could be adjusted.

As long as it is tested, these ballistas can be used to play their role.

This is a mobile ballista, and the process may be more sophisticated, because the arrows are replaced through the gear and then reloaded at one time, which can ensure continuous combat, so the design process required is more difficult than the existing ballista on the city wall.

"Brother Lu, whether you can make it depends on the two of you." Li Dedao.
