Since this heavy blow to the enemy, the opponent has been cowering in the camp under the city, and has never taken the initiative to attack. Although Li Yi also wanted to go out of the city at night to attack the enemy, he was later denied by himself.

Although the enemy was greatly intimidated, the strength was still extremely strong, and the enemy army outside the city was at least more than 20,000 men.

The strength of Yunnan's defense was already insufficient, and in the absence of foreign aid to echo it from afar, even if the whole army attacked, the attack power would not be able to achieve the desired effect, and I am afraid that it would be a pity to move the enemy with superior numbers.

And if there is a loophole, the enemy takes the opportunity to break through Pingyang Pass, then he will not be able to atone for his sins, and now in this situation of disparity in strength, he should still take steady defense as the first priority.

In addition, Li Yi is also thinking about a very important question. Originally, Yunnan has been committed to developing the economy, promoting the circulation of commodities, and increasing the income of the people, but now it has also seen initial results. However, in this turbulent and troubled world, it is absolutely impossible not to vigorously develop the application of military technology and to fully enhance the combat effectiveness of the armed forces.

Without the guarantee of strong military strength, the situation of stability and prosperity cannot be maintained, and long-term peace and stability are just empty words. Therefore, in the next step, while developing the economy, it is necessary for Yunnan to set up a firearms bureau and, under the guidance of Lin Qingliang, vigorously train firearms technical personnel, expand the technical application of firearms, and manufacture some practical and effective firearms to be used in future wars.

It's just that Li Yi is very troubled by the selection of candidates. Nowadays, people are accustomed to the confrontation of cold weapons, and they simply do not know anything about the use of firearms, so it is undoubtedly too difficult for them to learn to develop firearms. After all, he and Lin Qingliang have limited energy, and it is impossible to do everything, so it is still very necessary to find a capable person with certain expertise in this area.

Alas! Leave it alone for now, let Lin Qingliang and Li Hui preside over the establishment of the Firearms Bureau first, and then say, as long as we look for more malleable aspiring young people, gradually train them, and give full play to their initiative, there is nothing that cannot be done.

The cold night was long and difficult, especially since the enemy had not launched an offensive since then, and the defense of Binh Duong Pass did not dare to relax in the slightest. Idle and boring nights are even more difficult.

Li Yi and Yi sat on the Taishi chair on the city tower, thinking hard for a while about the bizarre experience of these two nights and a day, and gradually unable to open their eyelids, plus they have been personally leading the charge during the day, and the physical consumption is really not small, after persisting for a while, finally it can't hold on, and before you know it, Li Yi has fallen asleep with clothes.

I don't know how long I slept in a daze, but a rapid shout woke Li Yi from his sleep. Li Yi opened his eyes only to find that the sky had already dawned, and Yin Quan, Wei Jing and Lian Jun leaned over in front of Li Yi and were looking at him anxiously.

Li Yi hurriedly stood up and asked, "What's the situation?" Could it be that the enemy is attacking again? ”

Wei Jing's face was full of doubt, and he tried his best to suppress his excitement, and said softly: "Dashuai, the enemy doesn't know when he has withdrawn, although the camp is still there, but there is not a single soldier or horse in it, I don't know if the enemy has done some tricks." ”

"Oh!" Li Yi couldn't help but be stunned, the enemy actually withdrew? No way? Seeing that Pingyang Pass has been surrounded and has an absolute advantage, how can it be so easy to withdraw?

Li Yi Huoran got up and came to the lookout platform of the city tower and used a telescope to observe the enemy's camp.

Dayi Ningguo's attack on Yunnan this time was originally intended to be accomplished overnight, and there was no preparation for setting up camp at all, so the camps and tents were also erected in a hurry, only a row of sparse piles and 100 tents at the front.

But Li Yi carefully observed for a long time, except for the flags fluttering in the wind in the empty camp, there was no sign of human activity. Even the sights within a few miles of the vicinity were carefully searched, but not a single enemy soldier was found.

It seems that the enemy has been unable to attack for a long time, and has lost the confidence to break through Pingyang Pass in a short period of time. Moreover, in order to prevent the Yunnan side from taking advantage of the situation to pursue, they rushed away in the night, and they did not even have time to demolish the camp.

Li Yi immediately ordered Yue Wei to personally lead a cavalry team of dozens of people to intensively search for traces of the enemy within several miles of the vicinity. When necessary, the search area should be expanded, and it is necessary to carefully and carefully probe to prevent the enemy from sneaking up on the enemy.

After a morning of searching and reconnaissance, the cavalry team led by Yue Wei rushed back to report that not only was the camp of Dayi Ningguo under the city empty, but also within five miles of the vicinity, there was no trace of the enemy, it seemed that the enemy had indeed fully retreated, and it was obvious that he was in a hurry, and he did not even carry some of his baggage.

Li Yi was in doubt, and a message came from the scout team. After interrogation, the enemy commander did not know the specific situation of the retreat, but only heard that it may be that the army of Tonghai attacked Shanxian Mansion from several directions, and because the defense along the line was weak, he had to return to the defense, and it was not very clear how it was.

After getting this information, Li Yi didn't believe it at first. Oh, yes! How can there be such a coincidence in the world, Yunnan was suddenly attacked by the enemy, and it was only a little more than a day before the Tonghai side had already attacked Dayi Ningguo, which was really a bit of an amazing efficiency.

The only thing that can be explained is that Tonghai must have received the information of Dayi Ningguo's sneak attack on Yunnan in advance, so as to take the opportunity to move the Shanxian Mansion and want to make a profit.

But he didn't expect that Dayi Ningguo would not be able to succeed for a long time, and after getting the news of being attacked by a sneak attack, he withdrew his troops overnight, so that the two sides were evenly matched, and it was inevitable that they could not hold each other.

However, this move by Tonghai is extremely beneficial to Yunnan, which not only greatly reduces our positive pressure, but also indirectly supports Yunnan's tight situation. No matter what the situation is, Li Yi has to thank Duan Siping for this seemingly unintentional but effective plan to encircle Wei and save Zhao.

Although the enemy has definitely withdrawn, there is no room for relaxation here at Binh Duong Pass, and we should always be on guard against the enemy's return. In today's plan, we must send out people to carefully check the arming situation of each pass, and we must be foolproof.
