In the spring of 236, Yue Feng sensed the urgency of the form and decided to go south to pacify Huaikong Erzhou on the same day. As for the impossibility of attacking Western Shu, not only is it difficult to enter the Shu Road, but there are several Xiongguan seats, isolating the path to Shu in the west. Entering Wu from the sea is also unreliable.

Yue Feng ordered Ma Chao to lead 20,000 cavalry, Zhang Liao to lead 20,000 cavalry, and he took Green Butterfly, Zhuang Zheng, Zhang Feiyun, Tuoba Gui, Guo Jia, and Diao Chan led a total of 90,000 infantry and 30,000 siege troops, as well as a large number of trained civilian officials and newly promoted intermediate generals, and went south with all their might. A total of 160,000 troops attacked Huaizhou and Kongzhou respectively. Be sure to make it a success!

Yue Feng left Zhang Yi, Qing Zhi, Guo Qing, Yue Lei, and Dian Wei to guard Yan Zhao. And Diao Chan also replaced Yu Ji and grasped the temporary control of the assassin spy. Yue Feng officially divided the siege troops into infantry, they carried troops with armor, good at defense, good at attacking cities, good at digging pits and ambushes, good at making materials and equipment. Yue Feng felt that his two years of vigorous selection of training siege troops had not been in vain.

According to the intelligence, Wei Changzhi Huaizhou and Kongzhou originally had 150,000 troops, and it was only in the last one or two years that they had accumulated this by vigorously recruiting troops, and not only was their combat strength much worse than before, but in addition to the troops guarding the south and the prefectures and counties, the available troops for the northern defense were only 80,000.

Moreover, Tongzhou is very large and narrow, with as many as 120,000 troops, and it is extremely dangerous for Wei Chang to transfer his troops from the south to the north for defense.

The situation in the two states of Huaikong is like this, and Wei Chang has no choice but to seek an opportunity to win with one blow, because if Yue Feng divides his troops into three ways, then each road may be defeated one by one, although the final outcome may be a defeat for both, but it is better than being conquered by all.

However, Yue Feng changed his usual marching style, not only attacking the city step by step, but also striving to completely control the county seat and make it a solid Qin territory for each county he occupied. On the one hand, it is necessary to refine the new army with this battle, on the other hand, the past wars have also told Yue Feng that it is impossible to fight without damage, if you exchange two for one, even if you lay Huaikong, you will not be able to prevent Tongzhou. On the other hand, Yue Feng hopes to confuse Shu Wu with a more stable style. Now it is the safest way to reduce the meeting, and it is more risk-free.

Wei is often compressed by the army step by step, all kinds of wisdom are frequent, most of Yue Feng ignores it, and a small part is dismantled one by one, anyway, the performance of the siege equipment is improved, which is enough to conquer any county, city and state capital. His own troops also far exceeded Huaikong, and after occupying a county, Yue Feng would mobilize the Qicheng brothers and the original four counties to come to the new county and expand the southern border of the Qin army one by one.

Wei Changzhi's general Wen Bu wanted cavalry to raid the rear defense of the Qin army, but was caught by scouts all over the place, not only the gates of various county towns were closed, but there were catapults, and Wen Bu Wangcheng sighed with a small number of troops. Ma Chao and Zhang Liao also chased after him with 40,000 cavalry, and after Wen Bu lost a lot of troops, he could only retreat back.

During the southern offensive, Yue Feng took the application of catapults to the extreme, not only carrying the burden of people, but also moving around to chase the army. The earth and rocks are also dug wherever they go, and there are pits everywhere. In the siege of the city, Yue Feng was not satisfied with the siege of the city and the wall, the soldiers killed the enemy and occupied the city, but were not afraid of ink, and advanced meter by meter with catapults, until they occupied the entire city wall, full of catapults, with depth, there were guard troops, and then they ate away at the strength of the city step by step, not that the defenders saw that there was no way out, so they led the army to surrender. Yue Feng and the generals did not talk nonsense, and all of them were collectively brought to the military headquarters for training for one year and brainwashing.

In this way, Huaikong's forces were gradually compressed, and there was no opportunity to fight with a large corps.

Two months later, only 50,000 of Wei Chang's 80,000 troops remained, and 30,000 were consumed in endless tug-of-war. Yue Feng collected and surrendered the army, and continuously transported new soldiers from the rear to practice. Wei Chang finally knew that if this continued, he would have no way to retreat, he would not surrender Tongzhou or surrender Yuefeng, if he could not calm the world, what was the use of staying alive? ;
