The happiest person is Gao Jingming, who is in charge of finance.

Statistics from the Ministry of Land show that one-third of the country's land is in the hands of a small number of people, and these lands are the subject of land reform.

According to the Fengzhou model and the Yunzhou model, the imperial court could not forcibly expropriate land other than the land share of the equalization system, and must give compensation.

The amount was so large that the imperial court had to take out money to redeem it, and it could not be completed even if the treasury was completely emptied.

This time, the eldest grandson Shunde and others planned a rebellion, and many gate lords and big landlords participated, and their property and land were confiscated by the imperial court because of the crime of rebellion, which saved a lot of money for the imperial court, and Gao Jingming's pressure was greatly reduced.

After this rebellion, the eldest grandson Shunde, Li You and others were killed, Bai Bird Zhixiangzi committed suicide, six of the seven largest gate valve clans were suppressed, and a large number of the children of the gate valve families in the court were killed, exiled, dismissed and investigated, etc., basically eliminating the influence of the gate valve clan on the imperial court.

The only exception was Quan Gai Suwen, who, after receiving the news that the main force of the Tang army had not left, immediately reported Li You and Changsun Shunde and others, and was appointed by the imperial court as the deputy minister of supervision.

Li Ke escaped, and since then he has no dissenting intentions, and he has done things for the court in a down-to-earth manner.

Li Su dealt with it decisively, and the eldest grandson Shunde was killed, without implicating more children of the eldest grandson's lineage. The eldest grandson's vein has been more restrained since then, and for the eldest grandson queen mother, it has also removed a piece of heart disease.

The three main reasons for the fall of the Tang Dynasty in history were the control of the government by eunuchs, the division of feudal towns, and the party struggle.

For eunuchs to control the government, Li Shimin has already taken precautions, and the highest level of eunuchs does not exceed the fourth grade. Li Su even wrote the article that eunuchs are not allowed to interfere in politics into the law.

Land annexation was one of the important pillars of party strife and feudal separatism, and the imperial court held the ownership of land and controlled the land, the most important means of production in an agricultural society, thus eliminating the material basis on which the clan and the clan relied to oppose the imperial court.

Li Su abolished the fiefdom system and implemented the separation of military and political affairs, which greatly strengthened the centralized power system and basically eliminated the soil produced by the division of feudal towns.

As for party strife, all dynasties and dynasties have not been able to completely eliminate it, and the only way to do this is to strengthen the supervision system and weaken this phenomenon as much as possible.

Li Su came to the Tang Dynasty, and so far, has laid the legal system and political foundation for the continuation of the Tang Dynasty.

Having solved the domestic problem, Li Su can now specialize in foreign wars.

Damascus.

The caliph received a report from Harold that the Tang army had mobilized 700,000 regular troops to reinforce the Persian Empire, so that, together with the military strength of the original Persian Empire, the Arab Empire would face a million-strong army of these two countries.

The caliph was not ready for a war of this magnitude, and after thinking twice, he gave the order to withdraw his troops from the Persian Empire.

Persian Province of Ontario.

The caliph's third son, Hemar, was really unwilling to receive the caliph's order to retreat, especially after he heard that it was the caliph who gave such an order because he received a letter from Harold.

On the one hand, he wrote to the caliph, saying that even if there was no large-scale conflict with the Tang army, he would fight a battle in the province of Ontario in Persia, and even if he could not keep the province of Ontario in Persia, he would retreat to the second best thing and strive to keep the kingdom of Potter. He led an army of 150,000 to change into the costumes of the Potter Kingdom army and entered the Persian province of Ontario.

At 9 a.m. on November 24, 642, south of the city of Ahla, Ontario, Persia, Hemar led 150,000 Arab troops and 60,000 Potter Kingdom troops to confront the 80,000 Tang and 120,000 Persian troops led by Xue Rengui.

The Tang Army under Xue Rengui consisted of the 5th Cavalry Division, the 1st Infantry Division, the 1st, 3rd, and 4th Provisional Divisions of the Unu, the 11th Provisional Division of Silla, and the 17th Provisional Division of Goguryeo.

At 10 a.m., the battle officially began.

At the beginning of the battle, a 10,000-strong infantry unit of the Potter Kingdom launched a tentative attack in the direction of the Tang Army's central army.

The Tang army faced the enemy head-on with the provisional 3rd Division of the Unus. The two sides fired a flurry of arrows at each other, and then engaged.

The equipment and training of the army of the Potter Kingdom were all in charge of the Tang Army before the rebellion, and they were not much different from the Japanese slaves of the provisional 3rd Division. The two sides were in a stalemate from the start.

Xue Rengui and Hemar were both in their respective camps observing the situation on the battlefield.

The Japanese slaves joined the Tang army, they had no way out, only to fight desperately on the battlefield and prove themselves was the only way out. Therefore, the will to fight was strong, and a strong fighting power broke out.

On the contrary, the army of the Potter Kingdom is a puppet army, with no clear goal, and is forced to come to fight.

Half an hour passed, and the formation of the army of the Potter Kingdom began to waver, and the whole army began to retreat.

With a wave of Hemar's hand, two infantry teams of the Potter Kingdom were dispatched.

Xue Rengui ordered an attack. The Japanese slaves of the 1st and 4th divisions of the provisional division met them.

The two sides are stuck together again.

Xue Rengui's tactics looked a little clumsy, and he responded passively. He has his helplessness.

The Tang Army and the Persian Coalition Army, the cavalry force was only 15,000 people of the 5th Cavalry Division of the Tang Army, and the Persian cavalry was only 20,000.

The Arabs had 50,000 troops, and the Potter kingdom also had 10,000 troops.

In mobility, the Don Army was at a disadvantage. Xue Rengui could only shrink his forces to prevent the Arabs from scattering. He placed 20,000 men of the Persians on each flank to prevent the Arab cavalry from taking a detour and surprise.

Hemar saw the weakness of the Tang army, and sent two 10,000 troops to outflank the two wings, pinning down the Tang cavalry, and sending infantry to press head-on with all his might.

He concentrated 40,000 cavalry and prepared a frontal assault.

In the wilderness, the two sides continued to throw in troops and fought desperately.

The Tang army had a slight advantage in training and equipment, and the Arabs had relatively rich combat experience, and the two sides were at loggerheads.

The battle lasted two hours, and the two sides were still deadlocked.

Xue Rengui observed the situation on the battlefield, and still maintained the main force of the Tang Army in his hands, with the 5th Cavalry Division and the 1st Infantry Division as reserves.

The battle reached 12 noon, the Don army began to gain the upper hand, and the battle line was moving towards the opposing side.

Hemar had been waiting for the opportunity, waiting for the Tang army's front to be disorganized, and to use the superiority of cavalry to crush the Don army.

The Arabs began to retreat, the Don army began to pursue, the formation of the Don army began to move, and when the formation moved to the south, there would be chaos.

This was the moment that Hemar had been waiting for, and he ordered the cavalry to prepare for an attack.

Xue Rengui did not seem to be aware of the intentions of the Arabs, and commanded the Tang infantry to continue the pursuit.

The infantry of the Arabs retreated to the front of their own cavalry units and retreated to the flanks, and the Don army still continued to pursue.

At this moment, Hemar ordered the cavalry to attack.

"Boom", with the charge of 40,000 iron horsemen, the earth shook violently.
