After unified deliberations, the Northern Qi court could be regarded as reaching an agreement on the general strategy. Dugu Yongye sent troops first, took Hangu, Kehongnong, although since the establishment of Tongguan, Hangu natural danger has not been enough to fear, but Hongnong is still an important town.

Hongnong is the heart of Hedong, and since the East and West Wei have competed, its geographical advantages are particularly important. Yuwentai used this place as a springboard many times to attack the vicinity of Luoyang in the Eastern Wei Dynasty.

In the second year of the Eastern Wei Dynasty, the Western Wei Dynasty expected that the Eastern Wei Dynasty's troops in Hebei far exceeded that of Henan, so after the Battle of Heqiao, Wang Sizheng was ordered to carry out Hongnong, echoing with Yubi, and resisting the pressing situation of the Eastern Wei Dynasty together.

Compared with the jade bi standing abruptly in the strategic location of Fenqu in the Eastern Wei Dynasty, Hongnong's threat is obviously much smaller, but it cannot be underestimated.

Therefore, Murong Yan sent Dugu Yongye out of the first time and made it drive straight into Hangu, even if he couldn't take it, he would have to make it suffer heavy losses.

Dugu Yongye is a general, how to march and fight, no need for others to mention, moreover, Dugu Yongye has been guarding Luoyang for a long time, and he knows even more about the situation in Hedong and Henan than Duan Shao, he is the best candidate.

Under the situation of the Northern Qi army's pressure on the border, the defense of the northern periphery was tight, and in a hurry, many loopholes came out in one go, Dugu Yongye led the army commander to cross the Hangu one by one, and the Zhou army that came out to intercept was not decent.

Most of them are pretending, first sneaking open the side door, a loose horse rushed out like a thief, and quickly slipped away after a hundred or so steps with their eyes closed and a unified arrow, which is considered to be the completion of the task...... This kind of situation, even Dugu Yongye has never seen it, when did Zhou Jun become so disrespectful?

However, if you think about it carefully, the current situation in the Northern Zhou Dynasty is extremely bad, the population has decreased sharply, and many strategic places have been encroached upon by the Qi State.

Zhou Zhuyu Wenyong heard that he was an inspirational figure who wanted to revitalize the country, but his reform had not yet improved, and in a blink of an eye, the old enemy broke in...... Obviously, it is not given the rhythm of life at all.

Not to mention that there were still Chen Xin and Han Xiong, but these people beat Duan Shao a lot of times, look at their records:

"Duan Chen, the assassin of Yangzhou Prefecture in the Eastern Wei Dynasty, pulled out the city and fled. Xin led the righteous disciples to invite him in Jiuqu Dao, killed and injured many people, and captured Zhang Yi, the new order of Xin'an......

The Eastern Wei Dynasty sent the native Niu Daoheng to assassinate the history of Yangzhou, and Xin led his troops to break it......

and Li Yuanying Gao Zhongmi, still from the battle of the mountain. And the army returned to the west, regained the situation with Han Xiong and others, broke the three cities of the Eastern Wei Dynasty, and beheaded the defender of Kinmen County. 600 households. Looking for Yiyang County affairs. The Eastern Wei Dynasty reinstated Liu Pensheng as the county guard of Kinmen, and Xin beheaded him again......"

In the past, when Yaoxiong was in the Eastern Wei Dynasty, the Eastern Wei won more and lost less, and Hou Jing also won and lost half against the Western Wei, and when Hou Jing rebelled into the Southern Dynasty, the Northern Qi side basically couldn't pick out what they could fight with, so there was a huge army for a long time, but it was at a disadvantage.

Duan Shao can have today's level, thanks to the tireless sparring of others, it is conceivable how strong the strength of the Western Wei Dynasty and even the Northern Zhou Dynasty was in this area in the past...... But now that these people are gone, Dugu Yongye shook his head.

At this time, although the ministers in various places still had illusions about the Zhou State, they also had to plan for the future. If Dugu Yongye sends people to persuade him to surrender now, maybe they will all surrender......

However, the goal of Dugu Yongye's trip is not here, the soldiers are fast, and he has to quickly push to Hongnong City before the Zhou army reacts!

Counting the distance to be traveled along the way, Dugu Yongye couldn't help baring his teeth, and secretly scolded Yang Su for standing and talking without disgusting his back pain.

This long-distance run is really not something that he, a half-footed old man, can bear. Dugu Yongye turned his horse's head, broke away from the horse team, looked at the rolling iron horseman, raised his whip and shouted:

"Speed up, before dawn tomorrow, you must arrive in Huayin, and you can't keep up with the military law!"

Yang Su's bold plan made Dugu Yongye anxious, but it went all the way, and it was quite smooth, and soon after dawn, it was successfully pushed to the bottom of Huayin City.

The Zhou army defending the city was unguarded, and when they saw hundreds of cavalry soldiers descending from the sky, they were so shocked that they flew out of the sky, but they rushed like headless flies, and forgot to close the city gate......

Compared with the rapid progress of Dugu Yongye, Yang Su is unable to move forward in Xiaoguan, and if he wants to attack Xiaoguan, he must pass through Yiguan, which stretches through the valley, and there are many rivers cutting and east and west horizontal valleys...... And the road is extremely narrow, and the narrowest place can only accommodate one horse-drawn carriage to pass through.

Yang Yan used to guard the small pass, the Northern Zhou Dynasty has such a dangerous place, he can attack and retreat, he can come and go freely, if it weren't for his too floating, he can't say that there is no way for the Qi State to take him now, how could Lou Rui catch him? And now Yang Su is facing this problem, how to win the small pass?

Reserve is not lacking, the basic plate also has, in March of the second year of Heqing, Hu Luguang had built the military tun and the Great Wall near Yiguan (Xiaoguan) to fight against the Northern Zhou, in April, and levied 20,000 soldiers, Zhuxun Zhangcheng in the west of Yiguan, built two hundred miles of the Great Wall, placed thirteen Rong, Wuping two years, now on a big stroke of the pen, this place was renamed Huling Pass. There are 7,000 standing soldiers, all of whom are strong troops.

However, cavalry cannot be used to fight in this ghost place, and infantry is too slow, and the pass is too long, and no one dares to guarantee that there will be any variables.

Therefore, for more than ten days, Yang Su stopped outside the pass, and refused to move, but only sent a small number of sentry horses to investigate the route to see if there was any possibility of a surprise attack, but he did not dare to expand the momentum, lest he disturb the Zhou army stationed at Xiaoguan.

The generals also complained a lot because of this, and proposed to replace Yang Su, but they were not approved. In fact, Duan Shao and Murong Yan also had doubts in their hearts, the danger of Xiaoguan was that even they who were extremely experienced and experienced did not dare to say that they could win it, let alone Yang Su, a young man......

Although Yang Su is good at fighting and is an upstart in the army favored by His Majesty, after all, he has less experience. Therefore, they also had the idea of changing generals for a while, but somehow, the emperor had a tolerant and optimistic attitude towards Yang Su, even if he let thousands of troops go around in place, he didn't care at all.

The emperor's statement also put their doubts in their stomachs for the time being, after all, they are not idle and have nothing to do and stare at Yang Su every day, and there is a copper pea-like Wei Xuan on the opposite side to deal with, just pay attention to Xiaoguan's movements all the time.

Whether or not Xiaoguan can be won is related to the overall situation of the war.

Yang Su observed for a few more days in Yiguan, and found that there was really no shortcut, so he gradually calmed down and prepared for a bloody battle, but on the day he made up his mind, things suddenly took a turn for the better.
