The battle of Anshi Castle had not yet begun, but the lord of the castle had lost confidence in victory, and if this was known to the defenders and the people of the city, the outcome would not have been known.

But will Yu Rongchang let Yemei and Yang Yuxin leak the news? The answer, of course, is no. So after that night's conversation, there were inexplicably more than a dozen Goguryeo soldiers outside the courtyard, and in the name of serving the 'Ma' prince at any time, the two people in the small courtyard were closely monitored.

And aside from the side of Anshi City, let's talk about Li Chengqian's department outside the city, because of the strong support of Xuan Xunxue Xiaodaogu, the current Tang Army camp has been shrouded in a thick fog at all times, and people who don't know can't think that in the middle of the fog, there will be an army of 60,000 people entrenched in it.

"Brother Prince, do you really want to lock down the entire Anshi City? Don't let one out? It's a huge task, and it's impossible to accomplish it in a month or two. Xiaodao Gu Xuanxue Xun has been dutifully helping Li Chengqian during this time, and after using the Qimen method to cover the camp, when she heard that someone was planning to surround Anshi City again, she finally couldn't help but start complaining.

"Then take your time, anyway, we don't have all the equipment now, and there are still many soldiers who don't have winter clothes, rather than being idle like this, it's better to put some psychological pressure on the Goguryeo people and let them mess up." Li Chengqian didn't feel how unreliable his whimsical idea was, fiddling with an inconspicuous triangular arrow, but people fell into the so-called YY in later generations.

Qimen Dunjia was originally passed down from the Hetu Luoshu, and the legendary Zhuge Liang's Eight Arrays are also from the Hetu Luoshu, which means that if Xiao Daogu has no accidents, she should also know a lot about things like the Eight Arrays.

In this way, Comrade Xiao Li can basically be invincible for this Eastern Crusade. To see who is not pleasing to the eye, you can use the Eight Array Diagram to trap Ya and let her fend for herself in the big array.

Just like the Anshi City in front of him, if he can lay out the Eight Formations outside, then he has no need to attack it at all, as long as he waits outside, and goes in to collect the corpse in three years and five years.

Anyway, there are eight arrays, the people inside can't get out, the people outside can't get in, and after the food in the city is eaten up, the most faceted people have no other way but to starve to death.

"Brother Prince, Brother Prince! What are you thinking? The saliva is all out, it's disgusting! As the leader of Xiao Daogu, Cheng Lin has always been by her side, and where Xiao Daogu appears, there must be a little girl like Cheng Lin.

"Hiss......" As if reflexively, Li Chengqian sucked his saliva and touched the corner of his mouth with his hand.

"Haha......" As a result, a burst of laughter like a silver bell immediately erupted in his ears: "Brother Prince, you have been fooled!" ”

"Little girl, I fatten you!" Li Chengqian also realized that he had been deceived, glared at Cheng Lin fiercely, turned his head to Xuan Xunxue and said: "Xunxue, if you need anything, you can ask Siwen directly, if he can't solve it, you come to me again, in short, you must fence Anshi City for me within two months, so that it will become a lonely city, can you do it?" ”

"I'm afraid it's a little difficult, Anshi City is too big, it's not like our camp, and Qimen is quite particular about the terrain, and besieging a city is by no means as simple as imagined." Xuan Xunxue shook her head and did not directly agree to Li Chengqian's request.

Qimen Dunjia is a science, it involves many things in all aspects, and the important point is visual error. Of course, in the era of Datang, the word visual error has not yet been invented, and the only person who knows this word is difficult to find an opportunity to express himself because he does not understand the principle.

And since it is a science that uses visual errors, the focus is naturally on the vision, in the wild, according to different natural conditions, to create a special environment, such a thing may be something that Xiaodaogu can do simply.

But for a city is not so simple, after all, for the convenience of travel, the city is renovated all around, and the surrounding environment has become simple and single.

As a result, there are very few things that can be used, and there is less chance of visual errors.

This is just like a modern sniper chooses a sniper position, the more complex the environment, the more conducive to the sniper's concealment, and if it is an open concrete floor, then it is difficult for the sniper to find his own hidden position.

Li Chengqian didn't know how Xuan Xunxue used visual errors to make people misunderstand, but this did not affect him to know the simplest part of the principle, so he arranged for Xuan Xunxue to have as many as 20,000 auxiliary troops, and launched a crazy construction activity outside the empty Anshi City.

The Tang people are crazy!

This is the hottest topic of discussion in Anshi City, countless Goguryeo soldiers stood on top of the city, watching the Tang auxiliaries digging ditches below, stacking soil, and some people holding ropes to measure something on the ground, and then nailing wooden stakes on the ground.

What are these Tang people doing? Is it dividing the land? Or is it building a water conservancy? Yu Rongchang looked at the strange movement outside the city, and the whole person fell into deep confusion.

The city hasn't been beaten yet, and it's even thinking about development? Isn't that funny? If Anshi City is not fought in the future, the work being done outside will become the biggest joke of Datang.

Another point is that Yu Rongchang suspects that this is Datang covering up people's eyes and ears and preparing for the attack. However, no matter how he looked at the work going on outside, he could not see anything related to the siege.

Even if he pulled the guards to the city, the guy shook his head firmly after watching it for a long time, insisting that the work carried out by the Tang army outside the city had nothing to do with the siege of the city.

In the end, Yu Rongchang had no choice, so he personally ordered the 'Ma' son to be invited to the city, intending to let the 'he' from the Tang Dynasty come to see what the Tang army was doing and why it was carrying out such futile work.

"Lord of the city, please forgive me for being incompetent!" After seeing the busy state of the Tang Army outside the city, the whole person also fell into ignorance.

The army outside the city is the army of the Tang Dynasty, and the military uniform is indeed subordinate to Li Chengqian's team, but no matter how she thinks about it, she can't figure out what His Royal Highness is doing.

However, it is obvious that Li Chengqian must have done this for a purpose, although Night Charm can't figure out what his purpose is, but this does not affect her denial that she does not know the current situation.
