After Zhu Yuanzhang occupied Jiqing, he changed his name to Yingtian as the base of his army. At this time, Zhu Yuanzhang already had more than 100,000 troops. However, the current situation is still not optimistic. The Yuan Dynasty army was stationed in Zhenjiang to the east of Yingtian, Zhang Shicheng was entrenched in Pingjiang in the southeast, Zhang Mingjian's rebel army was stationed in the northeast, Yuan general Basil Buhua was stationed in the south, and Xu Shouhui was located in the west.

Among these people, Zhang Shicheng is the most intolerant of Zhu Yuanzhang. Zhang Shicheng was originally born as a salt dealer, and then made a fortune, entrenched in Jiangsu and Zhejiang for a generation, treated the people in Jiangsu and Zhejiang with generosity, and exempted these places from harsh taxes and miscellaneous taxes, so the people in these places have built shrines to worship Zhang Shicheng. Zhang Shicheng was proud, he originally thought that Yingtian was already in the bag, but he didn't expect that he would be taken away by Zhu Yuanzhang so easily, he was very unwilling, so he repeatedly attacked Zhu Yuanzhang.

Although Zhu Yuanzhang is the weakest, he has brave generals under him, and Li Shanchang and Chu Liuyan give him advice, so that Zhang Shicheng has fought hundreds of battles, large and small, although Zhu Yuanzhang did not win, but he did not suffer any big losses. It's just that it's definitely not a good thing for him to go on for so long. He frowned on this matter.

Recently, he has fought three battles in a row, but he often loses, and Zhang Shicheng seems to have known the arrangement of each of his battles, and he can catch Zhu Yuanzhang off guard every time, which makes Zhu Yuanzhang very depressed. These three battles caused Zhu Yuanzhang to lose more than 5,000 soldiers.

So, Zhu Yuanzhang quietly called Chu Liuyan and Xu Da into the camp tent to discuss countermeasures. Zhu Yuanzhang said: "In these three wars, each time we have arranged, it seems that Zhang Shicheng already knows about it? ”

Zhu Yuanzhang was thoughtful, Xu Da and Chu Liuyan already knew his intentions. Chu Liuyan then asked: "Marshal, do you suspect that some generals in our army are traitors and report to Zhang Shicheng?" ”

Zhu Yuanzhang nodded and said, "That's exactly what I thought." I wonder what you two think? ”

Xu Da pondered for a while and said slowly: "I don't dare to make assertions until there is no factual evidence. If you wronged your brother, it will inevitably make people feel cold. ”

Zhu Yuanzhang saw that Xu Da was cautious, which was his usual style, and he never blamed him, he said: "Ding Pulang, Fu Youde and Feng Guosheng came to take refuge from Xu Shouhui, could the traitor be one of them?" ”

"Marshal, instead of us being suspicious here, let's find a way to find out the traitor." Chu Liuyan tilted his head and thought for a while, and said, "I have a way to find out who is a traitor." It is better to raise the account tomorrow, and the marshal said that he would personally lead his troops to Langya Slope to rob and kill Zhang Shicheng's army. Then send men to guard the gates, and whoever goes out of the city will prove that it has something to do with it. If you start from the generals who went out of the city, you can get twice the result with half the effort. ”

"Okay, that's it!" Zhu Yuanzhang said earnestly: "Among so many people, I believe that the two of you are just Yuchun." Yuchun is more reckless, so I didn't let him come. Tomorrow we will see who will go out of the city, and I will leave it to the deputy marshal. ”

Xu Da immediately agreed. Between Xu Da and Zhu Yuanzhang, there were slowly some contradictions and suspicions. It's just that, but it's not clear. It is not only related to Xu Da's status and talent, but also related to Xu Da's affection for Chu Liuyan. It's just that at such a critical juncture, Zhu Yuanzhang was the first to think of Xu Da, which shows that he still believes that Xu Da is a person who is above board and has the same heart for him. This made Chu Liuyan quite reassured, after all, the allusion she saw from her mother's diary about Xu Da eating goose meat turned into her inner demon from time to time.

On the second day, Zhu Yuanzhang announced that he would personally lead his troops to Langya Slope to fight in accordance with the agreement that had been discussed. After they dispersed, Xu Da and Chu Liuyan came to the gate of Yingtian City to observe the generals who went out of the city. The two of them watched for a long time, but they didn't see each other.

Xu Da said to Chu Liuyan: "Liuyan, I think that person is going to go out of the city to ventilate the news, and I am afraid that he will not go out in this blue sky and daylight." Let's wait until the evening to come back. ”

Chu Liuyan shook his head with confidence and said, "Brother Xu, don't worry." If I hadn't guessed wrong, the man wouldn't have gone at night. There are so many people coming in and out of the city during the day, and it is not easy to attract attention when mixed in with the flow of people. It's different at night. The city gates are closed at night, and if you want to get out of the city, you have to use light exercises or think of other methods. And such a high city wall, unless it is light and strong, it is not easy to get out. I am afraid that it is impossible for the man to go out of the city by day, but by night. ”

After listening to Chu Liuyan's words, Xu Da agreed with her words. The two men continued to look down from the city walls. After a while, I saw Chang Yuchun striding out of the city. Chu Liuyan's expression was calm, and Xu Da was not in a hurry, Chang Yuchun was a brother who shared hardships with them, so naturally he would not betray them.

After another while, Fu Youde went out of the city. He was dressed in a weird way, very different from his usual clothes. If it weren't for Chu Liuyan and Xu Da fine, maybe he wouldn't have found out that it was Fu Youde. Seeing this, Xu Da glanced at Chu Liuyan, and Chu Liuyan was also looking at him. The two men looked at each other and smiled, continuing to monitor the people out of the city.

Fu Youde can't be the one who whistleblows. He really wanted to report the news, there was really no need to disguise himself and behave strangely to arouse the curiosity of others.

It was almost evening, and no suspicious person appeared, and Chu Liuyan was even wondering if he was mistaken, when Xu Da suddenly sighed: "I guessed that it was him a long time ago, and I really didn't guess wrong." ”

Chu Liuyan looked downstairs in the city, and saw a person making a walk and walking out of the city leisurely. This person is Guo Zixing's son Guo Tianxu. Chu Liuyan and Xu Da got down the city wall, followed Guo Tianxu far behind, and followed him all the way out of the city. All the way, he was very leisurely, walked for a long time, and when he came to a stone house where Orion rested, he stretched his waist, looked around, and walked in.

Chu Liuyan and Xu Da, performing light skills, followed behind. They hid under the eaves of the porch behind the stone house and looked through the small window. I only heard Guo Tianxu muttering to himself: "Grandma's, it turned out to be a deserted stone house." I was looking for something to eat, but now I'm going hungry. After Guo Tianxu finished speaking, he sat on the chair and complained for a long time.

Chu Liuyan almost thought that they were mistaken. Guo Tianxu was originally just a wild boy who couldn't eat enough to eat, but later recognized Guo Zixing, but it couldn't be a big deal. Chu Liuyan didn't take him seriously, until Xu Da saw him out of the city, and then they were almost certain that it was him. But in fact, now he sits in the stone house completely like a resting person, and no matter how you look at it, he doesn't look like a traitor.

Xu Da and Chu Liuyan looked at each other, but Guo Tianxu walked out. He walked a long way along the woods, and then followed the avenue to meet the celestial city. Chu Liuyan and Xu Da were still following from a distance, and Chu Liuyan said blankly: "Brother Xu, I think we are probably following the wrong person." This Guo Tianxu doesn't seem to be spreading the news. He hadn't seen anyone and hadn't done anything....."

When Chu Liuyan said this, his heart moved, and at the same time, Xu Da was also looking at her, and the two of them said two words almost at the same time: "Stone House!" ”

They no longer cared about Guo Tianxu, who disappeared into the vast twilight, and turned around and ran towards the stone house. The stone house in the distance was still in sight, and Chu Liuyan whispered: "I hope it's not too late." The two of them walked to the door of the stone house, and just about to go inside, Chu Liuyan looked down and saw that the two trees at the door were in a slightly wrong direction. Xu Da's feet were about to hit the ground, and he was pulled back by Chu Liuyan. As soon as they retreated, a Hidden Arrow was fired along the place where the two had just been.

"Who?" Xu Da asked in a deep voice.

Chu Liuyan pulled Xu Da's clothes and said, "Brother Xu, it's not a person, it's an organ." Someone has arranged formations and mechanisms in this stone house. If we don't follow the correct direction, we will be trapped and ambushed at any time. ”

Xu Da didn't know anything about the formation. Chu Liuyan pulled Xu Da, came to the back of the room, looked at the furnishings in the room from the small window for a while, and understood the formation of the cloth. She had originally seen the record of the Five Elements Bagua Array from her mother's notes. Her mother, Chen Sixi, is too lonely in this era. So he wrote down everything he knew. When Chu Liuyan was very young, Chen Sixi disappeared, and in order to miss her mother, she read the notes every time. I read each book dozens of times, but I didn't expect that the content in the notebook would slowly come in handy.

Chu Liuyan said to Xu Da: "Brother Xu, this formation is called the Tai Chi Bagua Array, and it is the simplest of the formations. He used the five elements of gold, wood, water, fire, and earth, as well as the eight trigrams of Qian, Kun, Zhen, Xun, Kan, Li, Gen, and Dui to set up arrays. The gossip of the five elements is constantly changing, as long as we find the right door and walk in, we will be fine. Although Chu Liuyan said it easily, he still carefully pulled Xu Da in.

Chu Liuyan followed the birth gate she found, and took Xu Da inside, and sure enough, she didn't encounter any danger. Chu Liuyan and Xu Da, in the room, walked around, but found nothing. Chu Liuyan remembered that after Guo Tianxu came in, he was sitting in front of the stone table. She went back to the stone table and looked at it.

Now, she finally got a glimpse of the mystery. It turned out that Guo Tianxu's hands were stained with paint in advance, and there was water on the stone table. At that time, he was scolding vigorously, Chu Liuyan and Xu Da only cared about him scolding, and they didn't pay too much attention to it, so that they didn't find the mystery in it.

Now that I can see it, Chu Liuyan and Xu Da suddenly realized. They cautiously stepped on the raw position and walked out, returned to Yingtian City, and reported the situation to Zhu Yuanzhang. On the other hand, they did not destroy the information in the stone house, hoping to use the information transmitted by Guo Tianxu to kill Zhang Shicheng by surprise.
