At the time of the fierce battle, the women and children, who could not help, had already begun to cook. At this time, as soon as the fighting stopped, the women and children carried baskets on the city wall to deliver food to the young men who had just finished vomiting. There is rice, but there are few real foods, and everyone's head can't get rid of the blood that happened, and they are in a trance holding their nest heads, looking at the sky in a daze.

Li Mu and Li Siwen didn't eat either, they really didn't have an appetite. Li Siwen leaned on the arrow stack, looked at the Turks from a distance a stone's throw away, and saw that they were also cooking on a fire. Suddenly, he had a lot of emotion, and said: "Brother Xian, look at these Turks, they know that once the reinforcements arrive, they have no chance of winning at all, why are these people still attacking the city without fear of death?" If they win, they are not the ones who enjoy the glory, and if they lose, they will die...... I really can't figure it out. ”

"What do you want to do with these useless things." Li Mu took a sip of water and said, "With the war, everything can't be paced with common sense. Maybe they have been blessed by the princess? Or maybe their relatives lost their lives in the Tang Dynasty campaign, and all kinds of reasons are possible, nothing strange. ”

Li Siwen sighed and said, "Actually, these people are all warriors. ”

Li Mu smiled dumbly and said, "Now is not the time to praise the opponent, let's think about how to deal with the next wave of siege." I think they're done eating, and they're supposed to continue, because there's not much time left for them. ”

Li Siwen suddenly said: "Brother Xian, there is one more thing I don't understand. Why do you say she wants to pass on the jade seal of the country, isn't that just a piece of jade, the Emperor Taishang and His Majesty don't have that piece of jade, and they have also laid down this huge country, if she can really help the previous dynasty, she can do it without this thing. Is it really worth it to spend hundreds of lives here for the sake of such a dead thing? ”

"If your majesty is allowed to choose, maybe a thousand lives, he is willing." Li Mu said a word, stood up with the city wall, and said: "But you reminded me just now, if we can find the heirloom jade seal, maybe we can use it as a threat to make her throw a rat bogey." ”

Li Siwen nodded, and then frowned again: "This city is so big, where can I find it." ”

Li Mu thought for a while and said, "Such an important thing is absolutely impossible to hide casually. Looking at Princess Yicheng's posture, things should not be on him, so they can only be in the hands of Queen Xiao. But when you search, you don't find it...... Where can she hide her things? Li Mu thought for a while, and suddenly a flash of inspiration flashed in his mind, and said, "Huh? Have you searched the house where they lived? ”

"Not really." Li Siwen suddenly furrowed his brows and said, "I remembered what you said, it seems that there are no names on the list of displaced people." ”

"Don't have a register of displaced people?" Li Mu hurriedly asked, "Didn't register?" Are you sure? Who did they place without registering? ”

"This ......" Li Siwen tried hard to recall, thought for a long time, and didn't remember, and said: "It should not have been registered, the register of displaced people was registered by me personally, and every name was written by me by hand, I don't remember the situation when my ancestors and grandchildren came to register together, besides, Queen Xiao's temperament is different from that of mortals, if I had ever seen her, when she had a dispute with the cooking woman that day, I wouldn't be surprised to see her." Well, not registered, I'm sure. ”

"Let's go to the yamen and read the booklet!" Li Mu suddenly thought of a possibility and urgently needed to be confirmed.

The two of them returned to the Yamen, found the book of displaced people, and looked through the end from the beginning, and sure enough, there were no names of Empress Xiao and Yang Zhengdao. Because each name was written by Li Siwen himself, he could correspond to a person for each name. After reading it from the beginning, there was no one who did not match the number, indicating that it was not a case of reporting a fake name, so that it could be determined that Empress Xiao and Yang Zhengdao really had not registered.

Li Mu confirmed what he thought, closed the list of displaced people, and said: "There is no registration, and people still appear in the city, which means that in addition to the city gate, there is also a way to enter the city." And Empress Xiao and Yang Zhengdao have not appeared on the street before, so there is only one possibility. That is, there is another secret room in the city, and when Wei Guogong broke the Xiangcheng, Empress Xiao and Yang Zhengdao hid in it, and hid in it for more than two months, until we found them, Xu had no food, and had to come out of the hiding place. The more Li Mu thought about it, the more he felt that it was possible, and said, "Does anyone know where they live?" ”

Li Siwen frowned and thought about it, suddenly patted his head, and said: "That cooking mother-in-law, she said that she followed Yang Zhengdao and saw Yang Zhengdao give the nest head to Queen Xiao, she must know where they live!" ”

"Go find him!"

The two of them hurried back to the city wall, looked for two gates, and finally found the cook at the south gate. After careful questioning, it was learned that Empress Xiao and Yang Zhengdao lived in the north of Dongfang, very close to the gathering place of Turkic nobles in North Street. Li Siwen recalled that when the Tang Army camp was stationed here before, the place where Empress Xiao and Yang Zhengdao lived was used to house the wounded soldiers. Later, the wounded soldiers left, and it was used to resettle the displaced people. They must have come out of the hiding place at that time, and the official in charge of the resettlement of the displaced people saw that there were people in the house, and thought that it had been arranged earlier, so they changed to the next one, so that there was a situation where they were counted as displaced people, but their names were not registered in the list of displaced people.

The two of them took people to the place where the cooking lady said, looked inside and out, and didn't see anything abnormal. But Li Mu was sure that there was a problem here, and said: "There must be a secret room, look for it, dig three feet into the ground to find it, even if the house is demolished, you have to find it!" ”

The crowd answered, using the knife in their hands as a shovel and tempted it everywhere. Li Muye and Li Siwen were also looking around, and suddenly heard a young man shouting: "There is a cellar here!" The two of them hurried over, and saw an open cellar by the stove, and the entrance was a square plank, which had been lifted to the side. The entrance to the cellar was only for one person to pass through, and Li Mu took the torch from the person next to him and went straight in.

Entering from the entrance, it was a space about two meters square, Li Mu looked around and saw a lot of rotten vegetable leaves, but the truth was a cellar for storing vegetables. But he didn't believe that Empress Xiao and Yang Zhengdao could live in such a closed environment for two months, Li Mu raised his hand and stroked the wall of the cellar, and suddenly touched a place with a different texture. The cellar was made of brick and stone, but here it was cold to the touch, like iron. Li Mu approached the torch, dusted off the dust, and found that it was an iron ring.

Li Mu grabbed the iron ring and tried to pull it, but he didn't pull it, he tried to twist it again, but it didn't move clockwise, and then he pressed it counterclockwise, and this time the iron ring moved.

As the sound of the machine sounded, a gap cracked in the wall from the middle, Li Mu continued to rotate the iron ring, the gap became bigger and bigger, and a secret passage appeared in front of his eyes!
