Under the attack of Hou Junji, Hemar and Harold, Delamb's strength was finally exhausted, and he was confined to a small area in Syria, centered on Damascus.

Later, he saw that there was no hope of dispersing the battle, so he took the several cities around Damascus and the young men in the surrounding area, carrying various supplies such as food, and took the initiative to retreat into the city of Damascus.

In the city of Damascus, there are 250,000 Damascus troops, and more than 600,000 people, and food and various supplies can support at least more than a year.

The walls of Damascus were extremely strong enough to withstand the attacks of the Tang artillery, and as for the city gates, they had been sealed with sandbags, and even if the city gates were blown up, they would not be able to enter the city.

Dramb is going to fight the trapped beasts, and the reason why he doesn't leave himself a way out is because he is waiting for an opportunity. If this opportunity is grasped well, he may still have a chance to live.

However, the premise of everything is to hold Damascus.

As Delamb gave up resistance from the rest of the region, the armies of all sides marched straight to the city of Damascus.

Hou Junji personally led an army of 500,000 men and occupied the southeastern part of the city of Damascus.

Hemar's 300,000-strong army and Harold's 320,000-strong army occupied the western and northern regions, respectively.

After decades of expansion, the Arab Empire has robbed a large number of gold and silver treasures, mainly hoarded in Damascus, and the three forces surrounding Damascus are now staring at these gold and silver jewels.

All three want to enter Damascus first, and if the relationship is not handled well, it is inevitable that there will be conflicts between the three companies, which will require negotiations.

Hou met with Hemar and Harold.

Hemar proposed that after the invasion of Damascus, Damascus would be divided into three zones, and no one else would be allowed to enter someone else's zone.

He took a map of Damascus and divided Damascus into three parts, with the main streets as the dividing line,

He demanded that the division be based on the direction in which the three are now controlled.

Harold did not do it, because in Damascus, the wealth and poverty in the various regions were uneven, and the original Arab palace was located in the west of the city, that is, in the area that Hemar had set aside for himself.

Hou Junji proposed that each of the three families attack the city, and whoever attacked Damascus first would not be allowed to enter the other two. His heart is very big, and he wants to swallow it alone, and he has artillery in his hand, and his ability to attack fortifications must be greater than that of the other two.

Hemar and Harold were well aware of the strength of the Don Army, and they immediately vetoed the proposal.

In the end, the three reached such an agreement.

First, Damascus was divided into four parts, with the southwestern two being the richest regions, and the rest being essentially the same in the east and north.

The agreement stipulated that the three would take turns attacking Damascus, and whoever attacked Damascus first would own the richest southwest. The remaining two outer two in the west and north are divided equally.

With a cycle of 10 days, each family plays for a total of 10 days, and if it can't be beaten, it will be replaced.

The city of Damascus was strong, and there were hundreds of thousands of troops in it, and it was very difficult to take it in a short time, and it was usually impossible to defeat it in a few months. Therefore, the first to attack Damascus will certainly not take advantage.

Hou Junji proposed to draw lots to determine the order of siege. Hemar and Harold said that the Don army had sharp artillery and might be able to storm Damascus in ten days, and they were willing to give this opportunity to the Don army.

Hou Junji disagreed, saying it was unfair.

Hemar and Harold desperately touted Hou Junji, saying that he was the god of war of the Tang Dynasty, and suggested that the Tang army should give the defenders a dismount first.

Hou Jun gathered great joy, and under the praise of the two, he nodded and agreed, and the Tang army took the lead in attacking the city.

The two brothers, Hemar and Harold, were on the same page when dealing with Hou Junji. But when they left Hou Junji's headquarters, they glared at each other and left.

After Hemar and Harold left, Gao Xianzhi said worriedly:

"Sir, you shouldn't say yes to them easily. The two brothers, Hemar and Harold, are obviously tricking us and consuming the strength of the Tang Army first.

I'm sure that even when it's their turn to attack Damascus, they'll grind and wait to drain someone else's strength. ”

Hou Junji said with a smile: "Brother Xianzhi, these two monkey cubs, playing clever in front of the old man, can they still hide it from the old man?"

You don't have to worry, I'll let you meet someone first. ”

When he said this, he shouted outside, "Captain Li, come in." ”

With the shout, a dark and thin young man entered, this person was Li Hou, the captain of Duhe's guard.

Li Hou stepped forward and saluted, saying, "See the two marshals for their humble duties." ”

Hou Junji said: "Li Hou, tell General Gao, what good things did you bring?"

Li Hou invited Hou Junji and Gao Xianzhi to his camp to watch the new weapons he had brought.

This is a strategic weapons unit secretly formed by the Tang Army: the Tang Air Force.

The Datang Air Force is a hot air balloon and airship unit. The principle of making hot air balloons and airships is very simple, it is a replica of the large Kong Ming lantern.

Since Datang has long had the upward power of gasoline, hot air balloons and airships, it is easy to solve. But the horizontal power is more difficult to do, the principle of gasoline movement, a post-era junior high school students understand, but the current process manufacturing level of Datang is not up to the level, the earliest Li Su wanted to use manpower, the use of pedal windmills to solve, however, manpower is limited, in the mouth can not compete with the wind.

He later came up with a solution and made a fire-breathing motive. The principle is to connect a thick empty pipe on the sealed gasoline barrel, and a row of slender nozzles stretches out from the other end of the empty pipe, when the gasoline flows through the empty pipe, it is heated outside, so that it is vaporized at high temperature, sprayed from the nozzle, and is manually ignited to generate power, and the effect is good. It is possible to fly 10 kilometers in an hour.

???? Speed control can be solved by adjusting the amount of gasoline flowing through the gasification pipe. An engine was also installed on the opposite side for deceleration and hovering.

Now Datang's steel industry exhibition is very fast, and the steel rolling process has also made great progress. Using windmills to provide power, Datang has a large rolling mill that can produce steel plates, copper and iron wire. All these provide conditions for the production of large hot air balloons and airships.

Li Su designed a large airship, 7o meters long, all steel structure, installed with six horizontal motors, and the load capacity can reach 5 tons. This airship became Li Su's landline.

Datang has now produced 5o hot air balloons with a load of 1.5 tons and 12 airships with a load of 2.6 tons, forming Datang's strategic air force.
