Lu Zheng woke up in an ordinary farmer's house. When he woke up, Doctor Wang was checking his pulse. Seeing that he was awake, he seemed to be relieved and asked, "Sir, are you feeling any discomfort?"

Lu Zheng shook his head in confusion, thinking of Zhang Lin and Niu Da. When he spoke, he found that his voice was hoarse, "How is Brother Zhang?"

Doctor Wang's expression immediately fell. He sighed, "Niu Da went to collect Old Zhang's body..."

Lu Zheng opened his mouth, but no words came out. He knew that under such circumstances, the probability of Zhang Lin surviving was very slim, but he still held the mentality that a miracle would happen. Now that Doctor Wang said so, he didn't know what else to say. He knew that Zhang Lin originally lived in the backyard, and if he wanted to escape, he would definitely be able to escape. He turned back to save them.

Lu Zheng whispered, "I'll go see Brother Zhang for the last time."

Because the posthouse was burned, Zhang Lin's body could only be left in the wild next to the posthouse. Some nearby villagers helped to build a mourning shed. Niu Da, wearing mourning clothes, knelt in front of the coffin in despair.

Lu Zheng burned incense. Although his legs were very painful, he still insisted on performing the complete worship ceremony. In the past, he sneered at these things, thinking that when people die, there is no need to do those formal things. But when he really traveled through time, he felt that perhaps there really were gods above the nine heavens. If so, please make sure these good people get good rewards.

Niu Da returned the gift and knelt there stupidly.

Lu Zheng walked out of the mourning tent and asked Doctor Wang who was waiting nearby: "How could this posthouse catch fire out of nowhere?"

Doctor Wang sighed: "It's dry here, and it's almost summer, so it's easy for fires to happen. Before I left yesterday, I advised Lao Zhang to be more careful, but I didn't expect..."

Lu Zheng asked: "Do you know where the fire started?"

Doctor Wang took him through the ruins to a courtyard and said: "It should be here. All the houses here are burned down. "It's clean."

Lu Zheng squatted down and used his fingers to pick up the dust on the ground, then stood up and walked around the yard, and then asked: "Doctor Wang, do you know what this yard was originally used for?"

Doctor Wang nodded: "I know, this was originally used by Lao Zhang to store grain. You see, there are two granaries here."

Lu Zheng pondered for a while before saying: "Since it is used to store grain, there can't be an open flame here, how could the fire start here?"

"I find it strange, too." Doctor Wang was also a little puzzled. "Old Zhang has always been a steady person. Every night before going to bed, he would check whether the fire in the stove was out. There used to be an old tree in the yard. He was afraid that the tree would attract lightning and burn the food, so he cut down the tree."

Lu Zheng also said, "Yes, a fire usually starts in the room or in the kitchen. How could it start in a warehouse?"

Lu Zheng stood there looking at the charred ground. Although it was a mess, the original layout of the house could still be seen. This courtyard is some distance away from where they live. Although the house is made of wood, the courtyards are separated by walls made of earth bricks. Now in this ruins, only half of the wall is left to reveal the original appearance of the courtyard.

Doctor Wang was still mumbling, "There was no thunder last night, how could a fire suddenly start... Alas, Lao Zhang is so unlucky..."

Lu Zheng shook his head, "He is indeed unlucky, but it's not because of God, but because he offended a villain."

Doctor Wang was shocked, "Sir, how can you say that?"

Lu Zheng pointed to the broken earth where they were standing and said, "Even if it was a thunderstorm, the fire should have fallen directly on flammable objects. Last night the wind was blowing from the southwest, and the fire should have gone to the southwest."

Doctor Wang nodded, "That's right."

Lu Zheng then went on, "But you see, the wall on this side has been completely burned and cracked, the entire wall is gone, and this side is The southwest wall of the courtyard is still half intact. Isn't this very strange? Moreover, this wall is an outer wall, which must be much higher and thicker. Soil and stone are not easy to burn, so why is it that something that should not be burned by fire is burned more thoroughly? "

Doctor Wang looked in the direction of his finger and took a breath of cold air: "This... Could it be..."

Lu Zheng pointed to the land near the outer wall again: "Although the grass and trees nearby are a little charred, they have not been ignited. This shows that the fire did not burn from this side, and it also shows that the wind direction last night did not change at all. In this case, it is extremely suspicious that this wall was burned like this." He paused, and said, "You said that you persuaded yesterday "But Brother Zhang should be more careful. Why? Even if there are frequent fires here, you can't suddenly say such a thing to him."

Doctor Wang shook his head and said, "I don't know what happened recently, but there have been several fires in the surrounding areas. The mayor sent people to visit every household to let us pay more attention to fire prevention. I thought that Brother Zhang lived far away and might not have heard the news, so I told him by the way. How come... Alas!"

Lu Zheng said very calmly, "I don't know what happened to those fires, but I can be sure that this one was man-made. The murderer splashed a flammable liquid on the wall and then set it on fire. Although this place is next to the official road, it is closer to other residents. "It's farther away, and the murderer chose to set fire to this side where no one lives. He should be familiar with Brother Zhang, or he knows Brother Zhang's living habits."

Doctor Wang frowned and said, "But Lao Zhang is the kindest person on weekdays. He won't even scold beggars who come to his door to beg for food. Who would have such a big hatred for him and treat him like this?"

Lu Zheng shook his head: "I don't know. The murderer planned it in detail, it doesn't seem like a spur-of-the-moment idea, so this person may have had conflicts with Brother Zhang for many years, which prompted him to commit this crime."

Doctor Wang pondered and finally said helplessly: "I really don't know who would hate Lao Zhang so much. Young master, why don't you ask Niu Da."

"I think so too." In fact, even if Doctor Wang didn't say it, Lu Zheng would also ask Niu Da, because although Doctor Wang and Zhang Lin have a good relationship, they are not together every day after all. Niu Da will definitely know a lot more about these things if he asks him.

The two returned to the mourning shed and told Niu Da about it, but no one expected Niu Da to react so strongly. He jumped up with red eyes and said, "Which bastard did this! I must cut him into pieces!"

Lu Zheng pressed his shoulder and said softly, "I understand your hatred, but now the most urgent task is to find the murderer. Think carefully, does Brother Zhang have any enemies on weekdays?"

Niu Da was shocked by his words. He calmed down a little after hearing what he said, but he still shook his head after thinking for a long time: "The postmaster is a very kind person on weekdays. No matter whether he is a neighbor or a guest, he always greets everyone with a smile. Although he sometimes has a bad temper, he is a man with a soft heart. He usually feels bad for scolding me. He and his wife are both good people. They are not rich, but they still help some poor people. Who would be so cruel to set him on fire..." At the end, Niu burst into tears.

Lu Zheng sighed in his heart. What Niu Da said was almost the same as what Doctor Wang said. But this was the most troublesome thing because the murderer's motive could not be determined. Trying to find such a person was like looking for a needle in a haystack.

Lu Zheng was not giving up, and said, "Think about it again, it's okay even if it's just a quarrel."

Niu Da cried and said, "There were... quarrels. There are a few scoundrels in Zhangjia Village. They like to take advantage of others. They were taught a lesson by the postmaster once or twice. And... and there's Wu Damazi. The postmaster used to buy vegetables from him, but later he found out that he was shortchanging us, so he changed to another store. Wu... Wu Damazi also threw feces on our wall... and..."

Niu Da said a lot of nonsense, but these were just trivial matters. Would they really make someone so crazy as to set fire and kill people? But no matter what, this is the only clue that can be found at present.

Lu Zheng was thinking about it, and was about to call Bao Zheng and others to go to the suspects' homes for questioning, but suddenly found that they were not with him, and this was not Qingxi County. Lu Zheng

smiled bitterly and asked Doctor Wang: "Doctor Wang, which department is responsible for this?"

Doctor Wang said: "This is still the territory of Guning County."

Lu Zheng nodded. No matter what, he had to go to Guning County. No matter whether the county magistrate was in charge or not, he would find the murderer to comfort Brother Zhang's spirit in heaven.

But now the horses of the posthouse had already gone to who knows where, and Juanyu had not returned yet. It seemed that he could only wait for Juanyu to come back here.

Lu Zheng was thinking this, Juan Yu said that he would probably be back around noon, and it would take about three or four hours. As he was thinking this, his stomach started to rumble.

Doctor Wang slapped his head and said, "I forgot that you haven't eaten yet, so why don't you eat first?" He said to Niu Da, "You should also eat something. Old Zhang certainly doesn't want you to get sick for him."

Niu Da shook his head and whispered, "Doctor Wang, you can go eat with this young master. I can't eat."

"You have to eat even if you can't eat. In case Old Zhang was really murdered, you have to take care of yourself and catch the murderer that day!"

These words seemed to ignite some fighting spirit in Niu Da, but he still shook his head: "I want to stay here to guard the post station chief."

Doctor Wang sighed: "Forget it, I'll bring you some food later." As he said that, he motioned Lu Zheng to go forward, "Young Master, let's go."

Lu Zheng nodded, and was not in the mood to be humble with him. He lifted the paper curtain on the mourning shed and walked out first. Who knew that as soon as he came out, he was embraced into an embrace that still carried the fragrance of dew and grass.

Rong Zhen's tense heart finally relaxed when he felt the intact body in his arms. He couldn't help but touch Lu Zheng's ear with his lips and said in a low hoarse voice: "Don't worry, I'm coming."
