The inheritance system of Sassanthemum Persia was exactly the opposite of the Tang Dynasty's "establishing chiefs but not establishing wise men", that is, "establishing wise men but not establishing wise men". Under normal circumstances, the emperor would choose a person among his offspring whom he thought he could inherit the throne, write down his name and seal it in a designated place. After the emperor's death, the ministers and the emperor's sons took out the secret letter together, and after the seal was opened, they immediately announced that the nominated prince was the new monarch.

But this secret model of establishing a crown prince has become useless after two palace coups launched by Kawad II and his son, especially the latter Kawad II, who acted more than his father.

After Kuss II's death, perhaps because he knew that the secret book was not his name, Kawad II immediately did something similar to that of Qin II and Hu Hai - ordered all his brothers to be killed, and even the hungry babies were not spared.

As for the handling of the daughters of Kuss II, Kawad II did not kill them like Qin II. He held a grand Zoroastrian saint marriage in Taisifon. Apart from a few women who had already married others, the rest, including Puran, Azami, and Esti, were all included in the harem, regardless of whether they were adults or not.

Then, after the plague that took the life of Khawad II and affected the palace, as well as the "Shahbalez Rebellion", the vitality of the Persian royal family was almost completely lost, and the ministers took over the power of the state and could even abolish the emperor at will.

According to Li Yao, the current Persian emperor Yi Si'ai III was just the product of Kussel II's love affair with a common woman. Since there were very few people who knew and were loyal servants of Kusel II, he escaped the inhumane killing of Kawad II. Although he was born among the people, he was raised by the hands of a woman's slave, and he did not undergo any hardship before ascending the throne. In the original history, Yi Si'ai III did not show any praiseworthy talents in his entire life, let alone let him turn the tide. From killing Rustam, the last pillar of the Persian Empire, to ending up casually dying at the hands of a miller, his speechless micro-work was almost endless.

In comparison, his sister-in-law, Estien, who survived the dangerous environment, had already passed the test of crisis and difficulties. She was able to escape from Taixifeng from the noses of powerful officials and safely travel through the Western Turkic territory in a state of war, and thus come to Chang'an, thousands of miles away from her hometown, which is enough to prove that she is not an ordinary person.

Therefore, although Estiva is still just a little girl under the age of 28, Li Yao did not underestimate the other party at all. She lowered her eyes and pondered for a long time before looking at Estiva again and asked, "In this way, are you planning to compete with your nephew?"

Seeing that she seemed very interested, Estien couldn't help but cheer herself up in her heart and immediately admitted: "That's right!"

"Well...it's interesting."

A faint smile appeared on the corner of Li Yao's lips. He gently raised a weak boneless index finger and pointed to the potted fruit tree placed in front of the soft couch.

Yu Xuanwei, who had always served as the background, only thought that his master was calling him. Just as he was about to make some move, Estien had taken the lead, picked a previously washed fig, cut it in half with a knife on the short table, and distributed it to Li Yao and Princess Jiujiang each, and then respectfully retreated back to his original position. Waiting for inquiries.

Li Yao's lips couldn't help but curl up two points. She was very satisfied that Estiu could still keep his posture low when showing his true identity. She swallowed a bite of the flesh and said with a faint smile: "You are indeed a sensible, but the distance between our two countries is really far, and the Western Turks are too big. I think you should know that getting a new territory always requires some time to stabilize the foundation. So I think with the benefits you just mentioned, it may not be enough to want my Tang Dynasty laborers to mobilize everyone to help you achieve your wish."

Estien bit her lower lip and said nothing for a long time, as if she was in a battle between heaven and man. After Li Yao finished eating, she slowly raised her head and asked softly: "What else do I have to do? The princess will help?"

Li Yao said: "I hope Persia can gift Marchianna to the Tang Dynasty."

Estien felt a stern, and she could see that this world's leading strong woman had a very strong desire to expand.

But before the other party put forward this condition, he also explained something to her in advance that even if he was as powerful as the Tang Dynasty, the control range of territory was limited.

Anyway, Persia has lost a lot of territory in recent years. Compared to preserving the Sassanian Empire, it seems that there is no big problem to cede a province.

Thinking of this, Estien nodded heavily: "Yes!"

Li Yao immediately smiled, his eyebrows and eyes curled like two crescent moons: "Okay! I'll help you with this."

When Estien heard this, she felt very happy and had a faint illusion of heart crying. However, she automatically ignored this feeling in a flash, because Li Yao had already taken the initiative to walk down the soft collapse, grabbed her hand, and smiled and said, "Don't stand all the time, come and sit next to me."

Seeing Li Yao suddenly become amiable, Estien forced himself to smile and bowed to her body: "Thank you Princess Long!"

As late autumn arrived, the Tang Dynasty's Western Expedition Army sent another good news.

The Tang army went out to fight the valley, and Murong Fuyun, the king of Tuyuhun, personally led the army to fight. The two sides fought against Haoshui. The Tang army won three battles. Murong Fuyun saw that the autumn grass was yellow, and while sending people to set fire, he fled west along the Qilian Mountains.

Li Jing ordered the chief marching commander of Qiemo Road, Li Daliang, the chief marching commander of Qiemo Road, Li Daozong, the chief marching commander of Shanshan Road, and the chief marching commander of Chishui Road, An Xiuren, the chief marching commander of Chishui Road, to jointly encircle and suppress Murong Fuyun.

Afterwards, Li Jing led the main force of the Tang army to move his troops to approach the West Sea. He encountered tens of thousands of cavalry of King Tianzhu in Niuxindui. Facing the highly morale Tang army, the Tuyuhun people were defeated in a battle. King Tianzhu led the remaining defeated generals to flee south. Li Jing and others did not stop, and soon the troops were approaching the Tuyuhun king's capital, Fuqi City.

King Tianzhu decided to clear the land and destroy all the pastures and farmlands around Fuqi City in advance, and tried to rely on Jiancheng to resist stubbornly.

Although the Tang army was in a hurry to supply, Li Jing was not in a hurry at all. He just built siege equipment and surrounded it without attacking.

After a few days of confrontation at the city, Chai Shao, the marching commander of Jishi Road, Li Shenfu, the marching commander of Yanze Road, Qi Daishuang, the governor of Yanzhizhou, and other troops arrived one after another, and also brought a large amount of livestock and food.

Seeing that the time was ripe, Li Jing immediately ordered an attack on the city. Because the Tang army was well prepared, they concentrated their elite soldiers and generals to attack a city wall. In just half a day, they were defeated. King Tianzhu escaped several miles outside the city and was beheaded by the general Su Dingfang of the Zhuangwu.

In this battle, the Tang army beheaded more than 19,000 ranks and captured more than 100 royal ministers including Tuyuhun's heir Murong Shun, the former Sui royal family prince Guanghua, and other royal ministers, 36,000 soldiers, and 170,000 men and women, which was a great victory.

However, just as the entire Chang'an City was immersed in the joy of victory, a cry sounded from Chengxiang Palace in the palace. The biological mother of King Xu, Li Yuanxiang, Yang Xiurong, "died due to illness". With the permission of the emperor and Concubine Wan, the princess of the Guru adopted King Xu in Xiande Hall. The news spread like wildfire and immediately attracted discussions from the government and the people...
