Li Yong, the leader of the arms dealers, constantly sold inferior armor and long knives to Datang, and let the peace messenger continue to instigate the contradictions between their countries, constantly launching border frictions, so that his weapons are sold on sale, and he makes a lot of money, and he doesn't have to worry about these countries threatening Datang at all, whether it is weapons and equipment, or personnel combat, it is impossible to compete with Datang, as for why not sell weapons to Li Er, because Li Yong's neck is not as hard as Li Er's steel knife, In just two months, Li Yong's wealth was rich and rivaled, because there was no bank at that time, his backyard specially vacated a place, and built a warehouse covering an area of more than 100 acres, which was full of gold, silver and copper coins, how much, only Zheng Liwan, who was in charge of money, knew that Li Yong would take care of these, everything was developing in a good direction, and a delegation was set off from Tubo, and their purpose was Chang'an of the Tang Dynasty.

"Sage, the Tibetan mission has passed through Shu and will soon arrive in Chang'an."

"What do you say about Tubo coming to my Tang Dynasty this time?"

"The land of Tibet is vast and sparsely populated, and their Songtsen Gampo has just unified Tibet, and under my powerful Tang Dynasty, this time I sent an embassy to probably form an alliance with us and seek our protection."

Li Er looked at the ministers in the hall who were tall and talking, and his heart was also beautiful, what about the powerful Turks, their Jieli Khan was not wearing women's clothes to dance to a certain person, and now he is not obediently retiring in Chang'an, a newly unified Tubo, how can it be the opponent of my Tang Dynasty, as long as he is disobedient, he will be destroyed casually, in the entire Taiji Palace, except for a few ministers, it is because they are more sober than those ministers who have been complacent and filled their brains, but there are only a few of these people, Among them, there are Du Ruhui, Fang Xuanling, Li Jing, and Xu Shiji, but which one of them on the golden chair is as overconfident as the ministers in the palace, and these famous ministers and generals all choose to keep silent and wait for the arrival of the Tibetan delegation to decide.

Therefore, people can't talk, the Tubo mission soon arrived in Chang'an, Emperor Li Er confidently only arranged for the Honglu Temple Shaoqing to be responsible for the reception work, Honglu Temple Shaoqing Cui Yong arrogantly took the Tibetan delegation to the embassy, and then arrogantly let a few of his subordinates accompany the Tibetan delegation to have a light meal, the Tubo mission saw such an arrogant attitude of the Tang Dynasty, they were all angry, and even wanted to draw a knife to cut those Tang officials who despised them, let them know that the Tubo knife is also very sharp.

"Da Lun, these Han dogs are so hateful, they are simply unsightly."

But their messenger reassured them, saying.

"Along the way, you have seen the strength of the Tang Kingdom, as well as those rich lands, this time here, in addition to forming an alliance with the Tang Dynasty, there is also to promote Tang Fan and relatives, so that we can get the book craftsmen of the Tang Dynasty, and I can also get time to recuperate, and when we have enough strength, I Lu Dongzan will lead you to occupy here, all of this will be ours, now why fight for a moment of righteousness, you are obedient, this time to the Tang Dynasty, you must not cause trouble, do you understand?"

If Li Yong is here, he will be careful when he hears Da Lun and Lu Dongzan, because Lu Dongzan is not an ordinary person, he is the first generation of Da Lun in Tubo, that is, the first prime minister of Tubo after unification, history says that his talent is like Yi Yin of the Shang Dynasty, Huo Guang of the Han Dynasty, Zhuge Liang of the Shu Kingdom, Wang Meng of the former Qin, and Zhao Pu of the Northern Song Dynasty. Such a great god was ignored by Li Er and others, and it is conceivable that they will deal with it more passively in the future, that is, if they don't die, they won't die. Ludong Zanli Ri expressed to Honglu Temple that he wanted to meet Li Er, but Li Er and his ministers planned to dry this group of Tubo missions first, suppress and suppress them, but where is Lu Dongzan so easy to deal with, not only did he not get angry, but also restrained the personnel of the mission, there was no need to go out in the embassy, and with the help of the Tubo merchants in Chang'an, he privately met with several ministers of the court, including the eldest grandson Wuji, he had a secret meeting with these ministers of the court and China, and bribed them with a large amount of gold, silver and jewelry, They naturally take people's money to eliminate disasters for others, within a few days, Li Er announced Lu Dongzan's Tubo mission to meet, Lu Dongzan, who came to the palace for the first time, and Li Yong's expression was similar, but what he thought in his heart was completely different from Li Yong, he thought that everything here in the future would be their Tubo, before coming to the Taiji Palace, he tidied up his clothes and waited outside the palace for the order, and waited for nearly half an hour before announcing him in, how could he not know, this was the intention of the Tang Emperor, it was nothing more than to give him a dismount and enter the Taiji Palace, Looking at the splendid hall, which was full of civil and military officials, he didn't dare to look more, and immediately walked forward to the main hall just the people on the golden chair to do the Tubo salute, the whole hall of civil and military people looked at this strong, but very elegant middle-aged man, Lu Dongzan's complexion was like a plateau person, his complexion was dark, and his face was obviously plateau red and very eye-catching.

"Tubo Dalun Lu Dongzan, see His Majesty the Tang Emperor."

Li Er was wearing a black dragon robe, with a crown on his head, and looked at Lu Dongzan below majestically, but Lu Dongzan couldn't see Li Er under the crown clearly.

"Excuse me, Lu Dongzan, why did you come to my Tang Dynasty this time?"

Lu Dongzan put down his right hand on his chest and said respectfully to Li Er, the emperor of the Tang Dynasty above.

"Your Majesty the Emperor of the Tang Dynasty, my Tubo unified Tubo under the leadership of the great Songtsen Gampo Zampu, I Tubo came to the Tang Dynasty this time, and I do have a few things to discuss with His Majesty the Tang Dynasty, the first thing is to discuss the alliance with you."

Hearing about the alliance, the civil and military ministers of the palace, including Li Er, were all happy in their hearts, and many people couldn't hide the joy in their hearts, and began to laugh and whisper to each other, but Lu Dongzan turned a blind eye to all this, Du Ruhui and Fang Xuanling glanced at each other, Li Jing and Xu Shiji also closed their eyes and were silent, Li Er saw that it was almost there, so he coughed and said very pretending to be thirteen.

"Okay, pay attention to the rules of the imperial court, Lu Dongzan for your request, I will arrange someone to negotiate an alliance with you."

"Your Majesty Emperor Xie Datang, in addition to discussing the alliance, we came this time, and I heard that the civil and military officials of the Tang Dynasty are all extremely smart people, all of them are people who have read poetry and books, and warriors with high martial arts, so I have three questions here to test the profound people and the strongest warriors of the Tang Dynasty."

When Li Er heard the second thing Lu Dongzan proposed, he actually wanted to fight with him in the Tang Dynasty, but Li Er was full of confidence in his ministers, and those ministers who boasted of reading poetry and books were not afraid, thinking that what would be the difficulty of the questions that a barbarian wanted to test, Lu Dongzan took the box handed to him by his subordinates on the side, and there was a wooden stick of uniform thickness and a piece of beautiful jade.

"Your Majesty the Emperor of the Tang Dynasty, the ministers of the Tang Dynasty, first of all, the first question is how to distinguish which end of this wood is the root and which end is the tail. The second question is to use a silk thread through the hole in this beautiful jade, and the third question is that it cannot be brought into the palace in the embassy, and when you answer these two questions, we will answer the last question together, I don't know if you dare to accept the challenge? ”

Now the ministers of the entire hall are silent, no one dares to say that they can solve the problem in front of them, that is, the first one they have no choice, how can they look at it is exactly the same, how do you know that one is the front and the other is the back? Can't solve it, it's a loss of national body, it's not as simple as the emperor's punishment, it's being made fun of by the world, and the reputation will be ruined, and the complacent Li Er has a gloomy face, and the ministers below who boast of reading poetry and books, as well as the look of making fun of people just now, are all dejected and lowered their heads, and no one dares to go up to challenge, at this time, fortunately, there are Du Ruhui and Fang Xuanling, Du Ruhui hurriedly came out of the queue and said to Li Er.

"Sage, today's Tibetan envoy wants to challenge our Tang Dynasty, then please let him put down his things, and after three days, he will definitely give him a satisfactory answer, Tubo Dalun, what do you say?"

Lu Dongzan looked at the purple-robed minister, and found the right person in his brain, Du Ruhui, one of the prime ministers of the Tang Dynasty, with unparalleled resourcefulness, so it was not good for him to fight him at the beginning.

"This lord said this, I Lu Dongzan didn't dare to disobey, three days later, please see His Majesty the Tang Emperor in the school, and then we will talk about the rest of the matter, I don't know what Your Majesty thinks?"

Originally, I heard that Lu Dongzan agreed, but when I heard that the answer was to be revealed in the school field, then at that time, the people of the whole city would definitely get the news and come to watch, if the puzzle was not solved at that time, it would be a shame, but now this situation cannot but agree.

"Okay, I promised you, I'll see you in three days."

Lu Dongzan and his subordinates bowed to Li Er and withdrew from the Taiji Palace, because he was very confident that these three questions would stump the ministers of the Tang Dynasty, as long as they were stumped this time, then the next issues of peace and affinity would be much simpler. Li Er looked at Lu Dongzan's two things, he looked at it for a while and then asked the eunuch to hold the wooden basin and put it up for those ministers to look at carefully, Du Ruhui and several ministers first picked up the wooden stick and looked at it, and then picked up the beautiful jade and looked at the small hole, after reading it, they were silent, and soon the two things spread throughout the hall, all the civil and military people looked at it, and found that these two things had no solution at all, the eunuch held the basin and carefully returned to Li Er, Li Eryi would pick up the wooden stick and pick up the beautiful jade for a while, and then asked the ministers below.

"Have you figured out a solution?"

There was silence below, no one answered, Li Er's fire value immediately increased, what about his ministers who knew the past and the present, and read poetry and books? Aren't you usually able to speak well? Drop the chain for me now? You usually tease me, don't you? At this time, the elder of the hundred officials, the elder grandson, stood up.

"Saint, please give us some time, we will be able to unravel it."

Li Er saw that the eldest grandson Wuji stood up, and he could only temporarily do what he said, now he saw that the people below were big, and he couldn't help but want to get angry, and those ministers who retired from the dynasty began to get busy, and went back to the house to ask their staff, looking for ancient books, and they were very busy, Du Ruhui and Fang Xuanling, who witnessed this, shook their heads, and Du Ruhui sighed.

"Alas, I knew that this time the Tibetan delegation must not be so simple."

"Yes, if we are stuck in these issues, the subsequent negotiations will be passive, and the strength of Tubo should not be underestimated, but it is a pity that those people are blind and can't see clearly."

And in the embassy, when they heard that their Da Lun was in the Taiji Hall, they were all very happy.

"Hahaha...... What is the Tang Dynasty and the Tang Dynasty, but so, Da Lun is really the wisest person in my Tubo. ”

Lu Dongzan and his delegation leisurely waited in the embassy to see how the so-called smart people in Datang solved several questions about him.
