"Alas!" Adulyadej Dawlai did not expect things to turn out like this, so he had to give up his efforts to persuade, he knew that Cai Lang was a descendant of the emperor of the Tang Dynasty, according to Ebu, the bloodline can be traced back to the period of the great four caliphs, he was able to serve as a deputy envoy in the Eastern Mission at a young age, and his talents must be good, as long as this marriage does not disgrace his lintel. So Aduly Daulai sent his attendant Ebu to ask Zhang Zhongyao about Cai Lang's family history.

The eunuch Ebu had a good relationship with Cai Lang, and after receiving this task, he first revealed a little bit of information to Zhang Zhongyao before he began to ask. Zhang Zhongyao didn't expect Cai Lang's envoy to make this trip, it was actually like the Tang general Xue Dingshan and Fanbang girl Fan Lihua in the play, obsessed with the princess of Fanbang, after careful consideration, if it is successful, the alliance of the two families will become a marriage, Wu Yingying has an extra guarantee in the river, and Cai Lang married the princess of Fanbang, Wu Yingying is magnanimous, loves and cherishes talents, and for the sake of the country, he must also be careful to beware of him. The important task of envoying to the Eastern Roman Kingdom could be done by the shrewd and capable Ann Sidao.

"Lord Waiter, this Cai Lang's father is the former benefactor of His Majesty of our country, he is the prince of the Tang Dynasty in the past, and he is also the only student of His Majesty of our country, and the future is great and limitless. Zhang Zhongyao said with a smile, and skillfully explained the relationship between the Tang Dynasty and the Xia Kingdom, and the tongue was bright lotus, and later Ebu reported to Adulyd Dawlai, becoming a long-lasting, noble Tang Empire was destroyed by the evil enemy, and the loyal and unparalleled general fought bravely to establish the Xia Kingdom, and also raised the orphan of the old emperor, that is, the Tang prince who was loved by Princess Sang Luzhuo.

"Your Highness Princess," Doyad flew into Sanrudro's chamber, as cheerful as a bird in the morning, "thanks to Allah, a miracle has happened, he is really a prince!"

The news that the king of kings was going to marry the prince from the east spread like wings, and just when Cai Langwei had no news of Sang Luzhuo for several days, the sudden happiness almost stunned him. Hurriedly followed Naebu's instructions and asked the matchmaker to propose marriage. In order not to lose the face of the big country in the marriage, Zhang Zhongyao made his own initiative and set aside more than half of the gifts given to Wu Yingying by the countries along the way as a dowry. After writing a marriage book and choosing an auspicious day to get married, the wedding was held in the Eternal Palace in the northern suburbs of Baghdad.

After the wedding, Adulyard Daulai felt sorry for his daughter, and left him and his wife to live in Baghdad for a month, Zhang Zhongyao did not urge, and secretly said in his heart that this Cai Lang was really a lucky general, and this envoy promoted marriage and alliance, which was no less than the merit of killing generals and capturing the flag in the battle array.

"Husband, is that beautiful song really taught by your master, His Majesty the King of Xia, and what kind of person is he?"

"Yes," Cai Lang replied in a deep voice, "Your Majesty will be in the middle of the soldiers every time he fights, and if the enemy is strong and needs to retreat, he will let go of his horse and walk with the heavily armored soldiers." ”

"Then he must be a stern king, will he reprimand you for taking a wife without his consent? ”

Cai Lang shook his head with a smile, "Never, whenever the war is over, he will ensure that every wounded sergeant is properly cared for, never forget to show mercy to the innocent people, and he often asks the priest to help the poor and the elderly." ”

He stroked Sang Luzhuo's silky black hair, and sighed: "He treats people kindly, and his subordinates and people regard him as if he were a parent to rely on, but he is not self-conscious, he always teaches others to point out what is wrong, he likes strange stories and objects the most, and the stories of Sinbad, which I told you in the past, were all told to me by my master when I was a child, and he will definitely be very satisfied if he ever sees you." ”

"Is he a kind elder?"

"Kindness?" Cai Lang couldn't help but laugh dumbly, and said in a deep voice: "Your Majesty, he started from scratch, fought thousands of miles of rivers and mountains, millions of people sincerely prayed for him, and tens of thousands of soldiers wholeheartedly supported him, but he was only in his early thirties. "The procession back to the East was extremely large, not only did the king of kings, Adulyd Dawlai, give Wu Yingxing a gift of one hundred camels, but also five hundred Mamluk cavalry escorted Her Royal Highness Princess Sangludro. Zhang Zhongyao bought more than 500 Arabian horses and Turkmen horses as stallions according to Wu Yingying's instructions, and hired ten horse breeders to return to Hexi with the team at a high price. In addition, the princess's dowry procession included a blacksmith who made Arabian swords, a pharmacist who made various potions, and a craftsman who served the princess, who is said to be the descendant of the architect who built the Hanging Gardens of Babylon.

However, compared to the priceless cultural classics, the rare treasure of a hundred camels is as light as a feather. In order to show the culture of Baghdad to the eastern countries, Adulyard Daulai sent a hundred scribes to copy for a month in the Hall of Wisdom, and copied a large number of classics, including more than 100 works by Aristotle, Plato, Hippocrates, Galen, Euclid, Ptolemy, Crodius, Pliny, Plotinus and other philosophers, medical scientists, mathematicians, and astronomers in the ancient Greek era, and more than 20 works on history, language, and literature in ancient Persia. There are more than 30 works on mathematics, and more than 20 books on agriculture and horticulture. These copies were shipped back to Hexi as the princess's dowry. I heard that after the Xia Kingdom Scholars compiled and sorted out the classics of the hundreds of schools of thought in the world, more than 20 scholars from the Baghdad Wisdom Hall were willing to travel to the East as advisors to the princess and exchange knowledge with Oriental scholars.

The envoy Zhang Zhongyao rode on the horse and thought proudly that China and Fanbang have always been more and less to take, and the most disadvantaged is the harmony between Princess Wencheng and Songtsen Gampo, which brought a large number of craftsmen and skills from the Central Plains to Tibet. This time, it seems that Huaxia has taken advantage of a lot of advantages, and the more he looks at Cai Lang and his wife, the more pleasing he becomes, and now if Adulyadej Dawlai wants Cai Lang to stay in Baghdad, Zhang Zhongyao may also agree.

The only regret is that because the wedding of Cai Lang and Sangludro was held with great grandeur, the princes and dignitaries of Baghdad rarely attended, and the surrounding Turkic princes got the news, and the Ghaznavid emir Mahmud, who passed by when the mission came, even declared that he would rob Princess Sangrudruk on the way back from the Eastern Mission and send her to his harem as a concubine. The return route of the mission would then bypass the Ghaznavids, redirect the part of Khorasan under the direct control of the Samanid dynasty, and then turn southeast, cross the Pamirs, and return to Khotan. Although the Samanid Dynasty was hostile to the Baiyi Dynasty, the country's monarch lost power, and the center was the Empress Dowager and the Cheng Dynasty, and the Turkic princes were not convinced, and the country's Khorasan governor Ifu Rahim Simugur was also the commander of the Praetorian Guard, and was busy competing with Prime Minister Utbi for power, and most of his army was stationed near the capital city of Bukhara, and his control over the Khorasan territory was relatively weak.

The last city of the Bailyi dynasty was Kerman, which is located in the southeast of Mount Kuhrud, rich in fine bronze and carpets, and there are large fields and gardens outside Kerman, which is dotted with an elaborate system of wells and canals, consisting of four parts: shafts, underground channels, surface channels and dams. The strong wind causes a large amount of water to evaporate, so the flow rate is stable. Kerman was also an important major center of Zoroastrianism, everywhere Zoroastrians who were willing to pay the faith tax.

After leaving Kerman, he entered the Khorasan region ruled by the Samanid Dynasty, which was a land of abundant water and grass in the desert, and for the ancient Persian kingdom, it was like the Hetao land in the Central Plains, and it was a barrier for the Persians to defend against the invasion of steppe desert nomads.

After entering Khorasan, Zhang Zhongyao, Cai Lang and Ahmod, the leader of Mamluk, all restrained their subordinates and guarded them tightly, Mamluk was not accustomed to riding horses and shooting, but was good at archery or riding horses, these people formed a battalion by themselves, and did not have much interaction with the soldiers of the Xia Kingdom, but they were extremely loyal to Princess Sangluzhuo. When he saw him off, Adulyadej Daulai said meaningfully: "The greatest merit of the Mamluks is not that they are brave and good at fighting, but that they are loyal to their masters and never betray them." ”

Starting from Baghdad, it was midsummer, and it was early autumn at this time, Zhang Zhongyao walked slowly according to the bridle, and as far as the eye could see, there was a scene of high autumn grass growing everywhere, the sunset reflected the returning birds, and the grass ears floated with the evening breeze, wafting with the fragrance. "If it weren't for Your Majesty's stabilization of the northwestern regions, in this season, I don't know how many Saiwaihu people would have gone south to fight the grass valley. ”

Seeing that it was getting late, Zhang Zhongyao was preparing to let the sergeants prepare to set up camp, but there was a horse galloping in the distant sky, Zhang Zhongyao's face was slightly gloomy, and he waved his hand to let the sergeants be on guard, and when he came to ride to see the banner of Daxia clearly, he released a chirp, which was actually the mark of the Chengying battalion, he ran to the front, then dismounted, and shouted loudly: "I am Xiao Heng, the centurion of the Chengying battalion, and I have a military intelligence report to Lord Zhang Zhongyao." This Xiao Heng was personally selected by Zhang Zhongyao into the camp and led a team of people to help protect the Chinese caravan in Samarkand, and Zhang Zhongyao immediately asked the sergeant to bring him up.
