"Yes, armor made of iron, including Mingguang armor." Li Ke nodded, Sassanid Persia and other Middle East countries actually do not have many iron weapons, of course, as an empire of several hundred years, Sassanid Persia does not lack armor, the problem is that now Sassanid Persia has not been killed by Arabia on the peninsula, and then lost a lot of armor.

On the whole, the iron-making technology of the West is far lower than that of the current Datang, not to mention compared with the Datang after Li Ke's improvement, the two sides are very different, they can't even compare with the previous Datang, so Sassanid Persia has armored cavalry troops similar to the Xuanjia Army, but there are not many of them.

"In that case, have you ever thought about a question?" Li Shimin frowned.

"What's the problem?"

"According to your thoughts, since you want to consume the living power of Arabia by selling weapons to Persia, then you know that the Arabia in your mouth, that is, the Great Food, is stronger than the Persian soldiers! Weapons and equipment are important, but winning a battle does not mean that weapons and equipment will be crushed. ”

"In such a situation, once we provide them with weapons and equipment, arm them, but they still lose the battle, it means that the enemy will get more weapons and equipment, and Persia will be destroyed faster." Li Shimin opened his mouth and said.

As an emperor on horseback, Li Shimin knows very well that weapons and equipment are important, but they are not absolute, and morale and other aspects are also very important.

Li Ke nodded, worthy of his father, looking at the problem is really tricky, Li Ke really ignored this problem, think about the combat effectiveness of the camel army after the armed in later generations...... It's still hard to say.

This is indeed a problem, but if this opportunity is missed, the rise of Arabia will be difficult to stop.

The most crucial battle of Kadihya will be fought in October of this year's Tang calendar (November of the Gregorian calendar).

"How's that, do you still sell it?" Li Shimin looked at Li Ke and asked.

"Otherwise, we will also drag the Western Turks into the water?" Li Ke suddenly raised his head and asked.

"Huh?" Li Shimin looked at Li Ke.

"Arabia has already fought with the Byzantine Empire, and if they defeat the Byzantine Empire and take Sassanid Persia at this time, they will have a full border with the Western Turks. If it's a slightly discerning Khan, it should be normal to intervene at this time, right? Li Ke said.

"In the seventh year of Zhenguan, I sent Liu Shan, the Shaoqing of Honglu Temple, to the Western Turks, and canonized the Ni He as the Xi Li Lu Khan of the Western Turks, Zhenguan died of illness in the eighth year, and his younger brother succeeded to the throne with the goose, last year, with the goose set up 500 horses, and the marriage proposal on the table was rejected by me."

"At this time, if you want to let them go to war, the other party may not be in the war." Li Shimin looked at Li Kedao.

Li Ke scratched his head a little, is Datang so strong at this time? The Western Turks are not good, but he forgot that the Western Turks were actually in constant civil strife at this time, and he did not dare to provoke the Tang Dynasty.

Looking at Li Ke scratching his head, Li Shimin suddenly felt a little happy, I thought you kid could solve everything, but now it's not good, right?

A Western Turk with civil strife is good for the Tang Dynasty, and the Western Turks started from the current civil strife, until the Tang Dynasty freed up their hands to clean it up, and the Western Turks did not rise again, so the Western Turks in this period are only countries that seem to have a vast territory, but in fact, they are weaker.

Since the death of the Tongyehu Khan, the Western Turks have no longer been able to command the strong khans of the various tribes, and each tribe is almost fighting on its own, although there is no civil war yet, but this has little to do with the Western Turks' demand for land contention.

At this time, in fact, even if Li Ke wanted to let Tong Goose participate in the war against Arabia, the other party might not be willing. Because there are only so many Western Turkic armies he can control, what if he participates in foreign wars at this time, and those tribes who do not follow him directly rebel?

"Do you support this strategy of mine, Father?" Li Ke pondered for a long time before raising his head and asking.

"Is it useful if I support it?" Li Shimin was a little helpless.

"Of course, if you support me, I have a way." Li Ke thought for a moment, and then said with a serious face.

"Then I support you, what can you do?" Li Shimin said directly without saying a word, in fact, Persia and Da Shi have nothing to do with the Tang Dynasty, so Li Shimin naturally agreed, if you talk about things with Goguryeo, it is impossible for him to agree like this.

The main Li Ke is too good at tossing, and the ghost knows what he can do.

"By sea!" Li Ke took a deep breath and said!

"By sea? It is possible to travel by sea, but it will take at least five to six months to travel from the Tang Dynasty to Sassanid Persia, are you sure you can do it in time? Li Shimin looked at Li Ke strangely and asked.

Now Datang Guangzhou Port has become the first port of Datang, the continuous development of the Maritime Silk Road, so that the land Silk Road of Datang has actually begun to decline from prosperity, although the sea ships of this era are still flat-bottomed sea ships, but also its cargo capacity is not comparable to the land caravan.

Hundreds of tons of cargo are enough in this day and age for even five months to make them a lot of money.

"Just in time." Li Ke is very confident.

The reason why it took 5-6 months from the port of Guangzhou to the vicinity of the Persian Gulf in later generations in this era was because the sea ships of this era were walking close to the coast, so the whole journey was more than 20,000 miles, and the speed was naturally slow, and there were constantly replenishment of supplies along the way, as well as trade with the kingdoms along the way. Oh yes, ships generally don't move forward on a moonlit night.

Such a time is naturally long, if you go straight to the Persian Gulf, and only replenish supplies along the way, you can arrive in about 3 months.

But Li Ke now has something better in his hands! A pointed-bottomed sailboat that has been proven by modern science! The advent of modern jibs allows sailboats to sail against the wind, with a pointed bottom, which means that the speed of the boat is much faster than the hard sails of Datang!

What's more, the ancients did not have sea charts and could only rely on the shore, but Li Ke had it! He has a complete chart of the entire sea area, and this chart alone is a valuable piece of information, and even he has meteorological information!

The most important thing is that the sextant for sea navigation, the telescope, and Li Ke can directly provide the finished product.

As a fleet with a special mission, it is also appropriate to provide the finished product directly.

The steady improvement of the underlying technology is extremely important, but when it is time to produce the finished product, it is also necessary to produce the finished product.
