At the beginning of January, Wen Yi stayed in Chang'an for more than half a month and finally completed the task satisfactorily, bringing back the materials needed for literature and art. It seems that Li Shimin now attaches great importance to scientific and technological research on the side of literature and art. And Wen Yi also brought back a sentence of milk tea, the original words were: "This is what I told Wenyi, Miss doesn't know." He didn't know how to give a gift to Miss during the New Year, so Miss Vain also made him a lucky bag. ”

Wenyi looked at the lucky bag in his hand and smiled bitterly, he actually forgot about this girl, and after thinking about it, he went into the house and made a "big white" silk doll about the same height as Shu'er, which was stuffed with sponges. Hold it up and look at it, quite satisfied. picked it up with a cloth, called Wen Yi and asked him to go to Chang'an again quickly, and give this rag doll to Shu'er. Let's just say that he worked hard to make this rag doll, and he didn't sleep for dozens of days, so it could be completed. Wen Yi despised in his heart: He only came out after entering the house for most of the day, and he exhausted his efforts, and the young master was too good at fooling people.

Because Wenyi wanted to teach Wang Erxuan to read and write, he never "hoped", but just gave them materials and smelting methods, and let them explore by themselves. The members of the special combat team were assigned by him to the old men in "Hope" one by one, so that they could help and familiarize themselves with the new weapons and equipment on the side. Their physical fitness does not need to worry about literature and art at all, and they are all men who can tear tigers and leopards alive. It is simply the most perfect hard labor for literature and art.

Wang Erxuan learns quickly, and literature and art are taught in a hurry, and the literature and art here on the stone side let him go to "hope" to study first, and then the literature and art are ready to let the stone be in charge of the affairs of "hope", so that he can engage in scientific research with peace of mind. In less than two months, "The Condor", "Three Kingdoms" and "Romance of the Sui and Tang Dynasties" have all been taught to Wang Erxuan, and he has also recognized all the words of these three books. Literature and art sent him back to his great storytelling career.

In the middle of April of the fourth year of Wude, spring sowing ended. Zheng Guo was killed because of Wang Shichong, and the crown prince Wang Xuanying ascended the throne as emperor but could not control the situation, causing Zheng Guo to be divided and weakened. Li Yuanji took the opportunity to lead his army to attack Wang Xuanying. Li Shimin strongly objected, because Datang is now becoming more and more powerful, and all forces are very jealous, if they send troops to destroy Zheng now, they will be united, and a large force will be formed to fight against Datang, and Datang may not be able to win. Unexpectedly, Li Yuan actually agreed to Li Yuanji's request to go on the expedition, and also took Li Shimin's position as the generalissimo of the world's soldiers and horses, and let him stay at home. Li Yuanji commanded 150,000 troops to attack Wang Xuanying, and he must eliminate Wang Xuanying's forces in one fell swoop and recover Luoyang and other places. The prince was spurned by the generals because of the last battle of Tianshui, so he is now very low-key, and he no longer competes to do things, and honestly starts a clay sculpture Bodhisattva in the East Palace. Li Shimin's Tiance Mansion was split by Li Yuan, and generals such as Cheng Yanjin, Qin Shubao, Li Jing, and Xu Shiji were all sent to Li Yuanji as marching vanguards. Li Shimin was helpless, drank all day to kill his sorrows, and no longer asked about anything.

Li Yuanji reorganized his troops and horses and marched to Luoyang in early May. One route was Xue Wanche as the main general, Li Jing and Qin Shubao were the vanguards, and led 20,000 people out of Changshui to the south to recover Songxian and Luhun; One route was led by Xie Shufang as the main general, Xu Shiji and Cheng Yanjin as the vanguard, and led 20,000 people out of Yucheng to the north to recover the Xiashi and Xin'an line. He led an army of 110,000 from Changshui to Luoning to Luoyang.

**The momentum is high, and Wang Xuanying's people have no fighting spirit and have no intention of resisting. Everywhere you went, you either opened the city and surrendered, or you turned and fled. Li Yuanji's army fought all the way to the city of Luoyang, ready to take Luoyang in one go, but was met with desperate resistance from Wang Xuanying. The high walls of Luoyang City are strong, Wang Xuan should have expected that ** would come, and he had already started to store grain, and now the food in the city is enough for his 80,000 troops to eat for two years. When he received the news of **'s expedition, he had already sent someone to contact Dou Jiande and others and asked them to send troops to rescue. Those heroes also understood the truth of cold lips and teeth, so they began to assemble a large army and march towards Luoyang. When Li Yuanji besieged Luoyang for three days, the armies from all walks of life were killed. Engage in a life-and-death battle under the city of Luoyang. Dou Jiande's army attacked from the left and led 50,000 troops; Xiao Xian led 30,000 troops to attack from the right side; Zhu Cang led 20,000 troops and Xu Yuanlang led 30,000 troops to attack from the rear; Wang Xuanying sent 80,000 troops out of Luoyang to be responsible for the frontal attack. Li Yuanji was full of confidence, and despite the persuasion of his subordinates, he ordered the whole army to assemble and prepare for a head-on confrontation with the local chickens and dogs in his eyes. He said: "This king's view is all rats, and my Tang Dynasty soldiers are wide, and a war can determine the world!" ”

As a result, after a day and a night of fighting, only 8,000 cavalry were left with Li Yuanji who fled. Qin Shubao was seriously injured and fell into a coma, Li Jing and Xu Shiji couldn't get out of bed, and Wei Chi Jingde was slightly injured, protecting the generals of Tiance Mansion to escape from the chaos, and he is currently missing. Cheng Yanjin, Xue Wanche, Duan Zhixuan and others were captured, Li Yuanji's generals suffered countless casualties, and there were only two or three unknown people left around him.

When the news reached Chang'an, the world was shocked. Li Shimin disregarded his identity, broke into the palace with a disheveled dress and a scruffy beard to make trouble in the Taiji Palace. Hundreds of civil and military officials stepped forward to dissuade him, Li Yuan also knew that things were going wrong, and now Luoyang has gathered nearly 300,000 troops, and now that Li Yuanji has been defeated, the next step is likely to attack Chang'an. Now that Datang only has 200,000 troops left, and it still has to be stationed in various places, and there are only more than 80,000 troops that can be recruited, how can it prevent the attack of 300,000 coalition troops? Li Yuan had no choice but to use Li Shimin again, the general of Tiance, and the whole army was under his control, and immediately organized troops to defend Chang'an.

Li Shimin returned to the palace and beat the drum to raise the account, but only a few people came, most of them were civil officials, and there were only one or two military generals left. Li Shimin sighed deeply, this battle is difficult. How to lead the army in battle if there are not enough generals? Although the eldest grandson Wuji, Du Rumei and others can also carry guns on their horses, they are not military generals after all, and they cannot command flexibly. In desperation, he had to assign the task of transferring troops first.

After the task deployment was over, Li Shimin hurriedly came to the study, took out the walkie-talkie and began to contact literature and art.

Wen Yi has been staying in "Hope" since the beginning of March, presiding over the construction of the "fusion energy reactor" and the training of special combat teams. The foundation of the large reactor is still under construction, and the material requirements are too high to be completed in a short time. But he first built a small reactor himself, and learned from Tony to make himself a set of mechs. The use of martensitic aging steel as the shell, which is the highest strength material that literature and art can make at present, can basically defend against the attack methods of the cold weapon era, except for the big killing weapon of the eight-bull crossbow. It took nearly a month to install the propulsion device, and it took nearly a month to get art, without the assistance of robots, Xiaomi is just an artificial intelligence for life assistance, and it can't provide much help to literature and art in this regard. I can only test it slowly, but fortunately, there are many people in "Hope" now, and all the mecha parts of literature and art are handed over to them to make them, so that I can free up time to study the propulsion system. It took three and a half months to complete the production of the literary mecha - Xiaomi No. 1.

The whole body is silver-gray, with dragon's head-shaped shoulder armor, a radio on the face, and can be connected to a walkie-talkie. There is a miniature reactor on the chest, two movable cuirasses on the chest, and the waist is spliced together by eight slender steel plates to ensure the flexibility of the waist. The back is forged in one piece, up to the waist, and the front and back of the leg part are fastened with screws. As a result, if Wenyi wants to put on and take off his armor, someone must help, otherwise it will be difficult for him to take a bath, but fortunately, he is very witty and makes a mechanism for his buttocks, so that he can solve the three emergencies at any time~

There is no infrared sensor; Without intelligent assistance, you can only use Xiaomi for some simple controls; There is no 360-degree camera without dead ends, and you can only rely on the two lenses on the mask to see the outside. It is only equipped with two miniature **, which is not very powerful, and the explosion range is thirty meters; Without lasers, energy is too scarce now, literature and art are reluctant to waste, and he can't build a laser emitter. Wenyi had to play a Fangtian painting halberd, two meters long, five centimeters thick, and the use of martensitic aging steel, in this era is enough to be called the world's first divine soldier. He used the remaining materials to make a Longquan sword for Li Shimin.

Literature and art put on Xiaomi No. 1, holding a Fang Tian painting halberd, hanging a Longquan sword on his waist, combining technology and cold weapons, majestic and full of mystery. Command Xiaomi to start the thruster, he wants to go to the sky! White flames erupted from the soles of his feet, and literature and art rushed into the sky in amazement. Inserting Fang Tian's painting halberd in his back, controlling the direction with his hands, literature and art flew arbitrarily in the sky, and performed various flying stunts for the hundred turtles below, which made everyone dizzy and fascinated. Just when Wenyi was preparing for a 360-degree Thomas spin and eight backflips, Xiaomi prompted: "Master, Li Shimin is calling you on the walkie-talkie." ”

Wenyi smiled and said, "Connect it." ”

Immediately afterwards, Li Shimin's eager voice came from his ears: "Xiaoyi, how is the training of the special combat team?" Something big is wrong. I want the special operations team to come back immediately. ”

Wenyi said strangely: "What's wrong?" They are now just getting acquainted with the operation of vehicles and helicopters, and are training in the combined use of various weapons, but they are still somewhat unproficient. ”

Li Shimin told Wenyi about Li Yuanji's defeat and the disappearance of the generals of Tiance Mansion. Wenyi frowned and said, "Your Highness, don't worry, I'll let them go now." You can give instructions directly with the walkie-talkie. After saying that, he immediately returned to "Hope". Everyone just wanted to step forward to compliment them, and Wenyi directly said to the special combat team: "His Royal Highness King Qin urgently needs your help now, go back and prepare immediately, each team will adjust the walkie-talkie to the first frequency band, and I want His Highness to report when it is ready." There's an urgent mission. ”

Everyone put away their smiles and said nothing, and immediately ran back to the room to prepare weapons and equipment. Wenyi also arranged for the people in the base to immediately start manufacturing a large number of ammunition and do a good job in logistical support. After everyone was assembled, Li Shimin asked them to find Wei Chi Jingde and them as soon as possible and bring them back to Chang'an safely.

The fifty members of the special combat team were divided into five groups of ten people by Literature and Art. Wenyi asked a group of three people to drive a helicopter to search with him, and the rest of them took a special military off-road truck made by Mengshi No. 2 to Yiyang to stand by. Wen Yi stayed at the base, Wen II was responsible for ammunition replenishment, and Wen San led ten men to follow behind the special combat team, ready to support at any time.
