When Lei Changye sailed back to Chang'an Jinchangfang, it had been seven days since the trial run of the camel cart. During this time, the Baiyinyi army in the southern camp of Chang'an increased by more than 10,000 people, plus more than 50,000 people who came off the ship of Feiyu Da Niang and the original army of Chang'an, the Baiyinyi army has expanded to 100,000 people.

Lei Changye unified the political envoys who came with the ship and the political envoys of Chang'an, and handed them over to Dongfang Shuo and Mao Sui for intensive training. Together with Xuanjin, he temporarily managed the 100,000 soldiers in the southern camp of Baiyinyi.

As soon as Xuan Jin arrived at the Protector's Mansion, she found the old members of the Martial Arts League who had a tacit understanding with her in the past, mobilized them all, and assisted her in leading troops to the southern camp for training. She herself is the main character, especially able to unite the indigenous members of the Martial Alliance, and the big players also have a deep affection for her and are willing to help her lead the army.

As soon as she appeared, the training efficiency of the entire Bai Yinyi Battalion was much higher than when there were fewer people before, sharing a lot of pressure from Lei Changye, allowing him to free up his hands and feet to focus on solving other problems such as logistics and supply and troop planning.

At this moment, Lei Changye's mind is planning the overall deployment of the Western Expedition, and what needs to be contributed here is the body of Emperor Kaicheng controlled by his divine sense. At this time, the news of the abundance of food and grass for the soldiers had already reached the Zichen Palace, which was particularly morale-boosting.

Although most of the officials of the Southern Government were not optimistic about the Western Expedition, now above the imperial court, the Military Machinery Province and the Commander of the Shence Army strongly supported the Western Expedition. And Bai Yinyi's military training in the southern camp every day shook the sky, and it also ignited the ambition of the ministers of the southern government to restore their homeland.

Taking advantage of this opportunity, Emperor Kaicheng, with the support of Cui Xuan and Wei Fu, the two new prime ministers, began the general mobilization of Jingluo Hexi, and ordered Fengxiang Jiedu to make Li Wei assist in attacking Qinzhou, Jingyuan Jiedu to make Kang Jirong attack Yuanzhou, Lingwu Jiedu to make Li Qin attack Anle Prefecture, and Shannan Xidao Jiedu to make Zheng Ya attack Fuzhou, so as to respond to the western expedition of Baiyinyi's army.

At this time, the Xihu army had heavy troops in Xiaoguan in the southeast of Yuanzhou, echoing the Yuanzhou defense area. Xiaoguan has been the Xiongguan of the North since ancient times, and there is a saying in the historical records: "Donghan Valley, South Kunwu, Xisanguan, North Xiaoguan". Xiao Pass is one of the four major passes in Chinese history, connecting the Great Wall of Qin and the old road of Xiao Pass, and is also the gateway to the north of the Tang Dynasty.

Since Xihu occupied Xiaoguan, the Xihu cavalry could release horses to the southeast when they left the pass, and arbitrarily attacked the northern border of the Tang Dynasty. At the same time, Xihu also opened up a communication channel with the Northern Barbarians, and the envoys often went in and out of the Northern Barbarians, promising high-ranking officials to lure the Northern Barbarians to attack the Tang Dynasty and weaken the Tang Dynasty's rule over the north.

Lei Changye led the army to the west, the first thing to knock out was the defense of Xiao Pass, as long as Xiao Pass was occupied, which had been choking the throat of the Tang Dynasty, the vast pastures of the northwest prairie would be open to the Tang army.

Therefore, the Battle of Xiaoguan was the most important battle of the Western Expedition. Xihu not only stationed tens of thousands of strong soldiers in Xiaoguan, but Master Wanzang also established a Yuanling Temple in Yuanzhou, stationed 500 Buddhist soldiers and several heads of Wanzang Temple in the top of the seven grades. These leaders and Buddhist soldiers were stationed on Xiao Pass, completely cutting off the possibility of a sneak attack on Xiao Pass.

This time, Emperor Kaicheng mobilized so many troops and horses to attack and harass the states, but also to distract the attention of the Xiaoguan defenders and lay the foundation for this crucial battle.

After Lei Changye arranged this series of dispatches, he finally gathered his mind back to the camel cart that was still wandering around the city.

Now that the camel cart has finally returned to Wang Mang's hands, he obviously saw Lei Changye coming back, and immediately ran over to drive, so as to show Lei Changye that he was not lazy. In fact, the rudder of this camel cart has passed through the hands of many people.

However, what made Lei Changye happy was that this camel cart was still running for so long, which showed that the operation efficiency of the Heavenly Pivot Spirit Array was extremely high.

Lei Changye found Wang Mang and asked him to drive the car back to the craftsman's bureau. He needs to study with him how to improve the camel cart into an armored vehicle similar to the armored vehicle to attack the city.

Originally, to attack Xiao Pass, Lei Changye didn't need many siege equipment such as donkey carts. His Flying Fish Lady ship could have flown to the top of Xiao Guan's head to bloodied the Xihu Army.

However, this time, the Baiyin volunteers of the Western Expedition came from all over the country, and they would also return to various places to recuperate after the battle. Showing the magic of the camel cart in front of their eyes is just the right time to promote the camel cart rental business for the future development of the Western Regions. When these silver righteousness returns to various places, the prestige of the camel cart will also spread.

When Wang Mang heard that there was something new to study, he naturally became more and more excited, leading Lei Changye to give him the new drawings and running away.

This new drawing was made up little by little by Lei Changye during the seven days of sailing, relying on the inspiration one after another.

This time the camel cart was modified, and Lei Changye comprehensively strengthened the camel cart according to the model of the armored car of later generations. Not only was the wooden defensive compartment designed around the carriage, but also a treasure wooden man holding a thunder sword.

This treasure wood bearer is not a new design of Lei Changye, but a battle doll that he conceived at the same time when he designed the royal housekeeper.

The outer layer of this Thunder Sword Man is wooden armor, and the inner layer is a skeleton made of a hundred steels, which is linked to the Five Thunder God Xiao Small Array in the core. Each doll needs to be activated by the Exorcism Talisman attached to 5 jade talismans in the Thunder Long Night, and once activated, only one Heavenly Thunder Talisman needs to be provided, and the Thunder Spell can be continuously fired 500 times.

Lei Changye also set up three buttons on the wooden man, corresponding to different thunder methods, which can be switched to hand-born gold thunder, water rolling mine and spiral fire mine at any time. It's just that because this Wuxiao God Thunder Array relies on the spirit exorcism talisman to maintain its operation, and relies on the contained Heavenly Thunder Talisman to stimulate the thunder method, the power is naturally not as powerful as the power driven by the thunder long night divine sense, so the grade of these thunder methods is only the power of the small three grades.

Because these five Thunder God Xiao Small Arrays were all designed by Lei Changye himself and activated with exorcism talismans, he could also invalidate the formation according to his own will. With this extra layer of protection, Lei Changye was not afraid that the Thunder Sword People would fall into the hands of foreign clans, and would turn around against the Tang people.

Lei Changye designed this Thunder Sword Man so that when selling camel carts in the future, he could also sell a bodyguard-type puppet, so that traders walking in the Western Regions could feel safer. And this time, when Xiao Pass is played, these thunder sword people and donkey-style camel carts can show their skills and increase their value.

Lei Changye's drawings to Wang Mang have already drawn the formation and design drawings, and he only needs to manufacture the parts and engrave the formation, and then he can assemble it, and he doesn't need to continue to bother.

After watching Wang Mang leave, he returned to the duty room of the Military Aircraft Provincial Administration and sat down cross-legged. At that moment, he suddenly saw the medicine man enter the room.

"Mr. Yao, why are you here?" Lei Changye hurriedly stood up and greeted him.

When the medicine man saw him, he walked over with excitement on his face: "Lord, good news!"

"Huh?" Lei Changye was slightly startled. Recently, the pharmacist has been acting for him in the palace for military affairs, and it has not been his turn to be on duty at the front line or in the southern camp, what good news will he need to tell himself?

"That's right, my lord, after I disperse, I often spend a while wandering around Loulan City in the painting box, chatting with the Qihu undercover agents inside, and inquiring about the war situation in Shazhou. Yesterday, a Qihu undercover agent came to announce the news, and I happened to hear it. I took it upon myself to inform Brother Jia and Brother Pang and asked them to arrange everything, and the Lord probably didn't have time to receive the news, right?" said the pharmacist with a smile.

"I see. Lei Changye suddenly realized. Yesterday he was designing the donkey-style camel cart and the Thunder Sword Man, and really didn't pay attention to what was happening in the painting box.

"Congratulations to the Lord, Shazhou Baiyinyi finally caught Achai and the ten Gui Dongdai cavalry of Subi raided the farmland in Shazhou, intending to attack the people of Shazhou for spring sowing. The Baiyin Yi army was led by Brother Kuang, one man and two horses killed on all sides, surprisingly encircled and suppressed, cooperated with the Guiyi army, and fought a beautiful battle of annihilation, the more than 10,000 cavalry who attacked were wiped out by 3,000 dead and wounded, and the rest were captured, and none of them ran away. The pharmacist said happily.

"Is there such a thing?" Lei Changye was overjoyed. Xihu's cavalry is the most troublesome type of troops, with strong combat power, fast maneuvers, attacking and plundering like fire, coming and going, and extremely difficult to capture. At the same time, raising a group of cavalry also requires Xihu to pay a lot of costs. If more than 10,000 Xihu cavalry can be annihilated, this will be a heavy blow to Xihu.

The only thing that is a little regrettable is that it turned out to be Achai and Subi cavalry, and the main force of the Xihu headquarters did not lose.

"The art of war has clouds, and ten rules surround it. I didn't expect Kuang Zhang and them to encircle and annihilate 10,000 people with less than twice the force, what is going on?" Lei Changye asked curiously.

"Brother Pang had a clever plan to let the Guiyi Army pull out a batch of mares and put them on the edge of the farmland. Many of Achai and Subi cavalry rode horses, and they were in estrus in the spring, and they didn't want to die when they saw the mare. hugged the horses together, and Achai and the Subidian cavalry couldn't run away if they wanted to, so they could only be led into the ambush circle before their eyes. Some Hu people thought that the gods of heaven blessed Baiyin and obeyed, and the whole team surrendered. The medicine man clenched his fists excitedly as he said this.

Obviously, Pang Hengyi's beautiful horse trick made the pharmacist like it very much, and he was really envious of him. As strategists, it is their destiny to be able to apply what they have learned and create results with their own wisdom on the Hanhu battlefield.

Although Qiu Shiliang has a sense of accomplishment following Lei Changye's calculations, the real sense of accomplishment really comes from the battlefield.

Lei Changye smiled slightly. Pang Hengyi's beautiful trick is exactly the same as Li Guangbi's trick against Shi Siming, which is really the same as what a hero sees.

Jia Xu and Pang Hengyi, one waited for Xihu to throw himself into the net, the other used a beautiful horse to trap the Xihu cavalry, and Kuang Zhang operated perfectly as the executor. The three of them have found their place in Shazhou, and it seems that Shazhou should have nothing to worry about under their care.

"Mr. Yao, Bai Yinyi can go into battle from another month of training, and when I go west, I also need you to serve under my account to break through the Xiao Pass together. Lei Changye said in a deep voice.

"Your subordinates should serve wholeheartedly!" the pharmacist bowed and saluted with his eyes shining.
