The Tian family was also a family that was set on fire, but it seemed that the Tian family was in much better condition than Zhang Shi's family. At least they were ready to start building a new house.

When Lu Zheng and his team went there, only the two elders were at home. The other two sons were out cutting trees. When they heard about Lu Zheng and his team's purpose, the two elders immediately poured tea and invited them to sit down.

Lu Zheng took the teacup and smiled: "You're welcome. I just want to ask you something."

Old Man Tian said "ah" twice in embarrassment: "You say... say..."

Lu Zheng asked: "How long ago did your house catch fire?"

Old Man Tian thought for a moment and said: "About twenty days..."

Lu Zheng and Doctor Wang looked at each other. According to the time, this was probably the second house to catch fire. He asked again: "How did the fire start?"

Old Man Tian sighed: "I think the fire in the stove was not extinguished, so it burned the firewood pile next to it..."

Old Mrs. Tian on the side spat at him: "I remember it very well, the fire in the stove was basically extinguished."

Old Man Tian glared at her again: "Maybe you forgot? If it wasn't for the stove catching fire, Where did this fire come from?"

The two were about to quarrel, and Doctor Wang came over to act as a peacemaker: "Come and take a break, this young man also thinks that this fire is a bit strange, so he came to ask." Old Mrs.

Tian glanced at him and said to Lu Zheng: "Young master, this fire is really strange, it can't be put out even with water, and the more water you pour, the more fiercely it burns. Don't you think it's strange?"

Her words verified Lu Zheng's previous assumptions about flammable materials. If it was an oil fire, it would not be put out with water. Lu Zheng had a clue in his mind, and asked Mrs. Tian again: "Auntie, have you ever seen a kind of black water that smells bad and is easily ignited?"

As soon as Lu Zheng asked, he found that Mrs. Tian's face changed instantly, and it was old man Tian who smiled and said: "What are you talking about? What black water?"

Lu Zheng could tell at a glance that old man Tian was lying, but he pretended to know nothing: "In that case, we'll take our leave first..."

The two elders hurriedly saw them out.

On the way back, Qingluan couldn't help asking, "Master Lu, they were clearly lying just now, why didn't you expose them?"

Lu Zheng shook his head and asked Doctor Wang, "I saw a lot of prey in the yard, which shows that the Tian family is living a good life. At least the other two sons of the Tian family are capable. Since there are people willing to marry someone like Zhang Shitou, why don't they want to marry someone from the Tian family?"

At this point, Doctor Wang's face looked a little ugly, but he still said "The Tian families moved here almost thirty years ago. At first, the villagers had no prejudice against them and were even kind enough to help them build houses. But who would have thought that there would be three consecutive years of drought after they arrived. Later, several families went hunting in the back mountain together, but they didn't catch any prey and were left in the mountain by the mountain god. The only one who came out alive went crazy, so Li Zheng ordered people to seal off the back mountain. Later, rumors spread that the Tian family was unlucky, and the villagers gradually stopped wanting to associate with them."

"So what happened in the mountain?" Lu Zheng asked.

Doctor Wang shook his head: "I don't know much about this. It is said that Li Zheng once took a few young men from the village to the mountain to have a look, but everyone who came out kept their mouths shut.

Li Zheng then ordered the mountain to be closed. Now, thirty years have passed, and no one has entered the mountain again even if the situation is very difficult." Lu Zheng seemed to be thinking about something, but Qing Luan narrowed his eyes and said: "Could it be that the Tian family has entered the mountain?"

Doctor Wang was shocked: "How is this possible?!"

"I think Qingluan is right." Lu Zheng suddenly said, "Just now the two elders of the Tian family said that their two sons went out to cut trees. Given their relationship with the villagers, I'm afraid they can't go to the village woodland to cut trees. Where else can they go except the back mountain? Besides, the dried meat and furs in their yard are obviously very skilled. Where else can they hunt so many wild game?"

Doctor Wang frowned and said, "No, I have to tell Li Zheng about this."

Lu Zheng shook his head and said, "They are not liked by the villagers. I think they have to go to the county to buy many daily necessities. If they don't have hunting to supplement, I'm afraid they would have died long ago. This is also helpless."

"But..."

"Doctor Wang, I am very concerned about what happened in the mountain. If possible, I want to go into the mountain to take a look."

Doctor Wang's face suddenly changed: "No, no! Master Lu, Li Zheng once said that no one is allowed to enter the mountain, otherwise there will be punishment from the gods."

Lu Zheng said: "I saw that the Tian family should have been there more than once, and they are fine. And I think the key to this case should be in the mountain."

Doctor Wang could not persuade him, so he could only sigh: "In that case, ask Master Lu to come to Li Zheng's house tomorrow morning. I can't make the decision on this matter."

"Of course."

When Lu Zheng came back, Rong Zhen was playing chess in the room. Lu Zheng walked over: "It's not boring to play chess alone. Let me play with you."

Rong Zhen stopped and curled his lips slightly: "I didn't expect you to play chess."

"I can't." Lu Zheng denied it confidently, and then smiled and said, "But I know another way to play chess. I'll teach you."

Rong Zhen raised his eyebrows: "Is the case solved?"

"Not yet, but there are some clues." Lu Zheng didn't even raise his head, and concentrated on tidying up the chess pieces on the board, "Okay, then, I'll take the black and you take the white."

Rong Zhen took the chess box and made a gesture of invitation.

Lu Zheng placed the black piece directly at the Tianyuan position, and then said: "This game is called Gobang, and it depends on who can connect the five pieces in a line first. How about it, easy, right?" Lu Zheng's smile was a little cunning. He thought about when he was in high school, he and his desk mate drew a chessboard and chess pieces on draft paper. At that time, he was invincible in the class. It should be easy to beat an ancient man who had just learned it.

Rong Zhen played a few moves with him, then nodded and said, "I understand."

Lu Zheng crossed his hands under his chin and said maliciously, "Since you know how to play, how about we make a bet?"

Rong Zhen leaned back slightly, playing with a white piece in his hand, and smiled playfully, "Oh?"

Lu Zheng spread his hands, "How about three games and two wins? I'll let you play black."

Rong Zhen dropped the white piece in the chess box, and raised his lips, "Okay."

However, a quarter of an hour later, Lu Zheng looked at Rong Zhen in disbelief as he casually dropped a black piece next to the four connected pieces, and then said to Lu Zheng, "Thank you."

Lu Zheng said unconvinced, "This is only the first game, let's play again!"

Rong Zhen handed over the black chess box in a good-tempered manner. Lu Zheng choked, but Rong Zhen said, "Isn't this fair?"

Lu Zheng was like a cat with its fur standing on end: "I told you to play black, so you play black. A real man should stick to his word!"

"You are quite courageous." Rong Zhen smiled softly and put the black chess piece back.

Lu Zheng stared at him fiercely: "I will definitely not lose this time."

Rong Zhen raised his eyebrows and slowly put the black chess piece down.

Looking in through the open window, the incense burner on the table was burning with curling green smoke. A man in a wide robe with wide sleeves was leaning on the pillow with his forehead supported, looking at the boy opposite him who was thinking hard. A faint smile at the corner of his lips softened the coldness between his eyebrows, just like the gentle breeze in this weather. The crisp sound of chess pieces falling echoed in this small courtyard, and suddenly there was a sense of peace and tranquility that people couldn't bear to destroy.

However, after two quarters of an hour, no matter how careful Lu Zheng was, he could only admit defeat helplessly. He stared at the chessboard and muttered to himself: "Impossible! This is absolutely impossible!"

Rong Zhen stood up and dragged him away from the chessboard: "Eat first."

Although the food was not rich, it was delicious. However, Lu Zheng had no intention of tasting it. He was still thinking about the game just now. When a piece of food was brought to his mouth with chopsticks, he ate it. After eating, he realized something was wrong. He raised his head and saw Rong Zhen taking the chopsticks back. His face suddenly turned red.

"You, you, you...what are you doing!" Lu Zheng stammered, "Eat...eat well!"

"You are the one who is not eating well now." Rong Zhen said calmly, and continued to pick up the food with the chopsticks without any hesitation.

Lu Zheng felt a little aggrieved. To be honest, he had never taken advantage of Rong Zhen. He blurted out, "Can't you just give in to me?"

Rong Zhen turned his head and raised his eyebrows slightly, "Is that so? I'll remember it next time."

Lu Zheng was stunned. He knocked his head on the table in despair and muttered, "Let me die..."

Rong Zhen picked up some food for him and said, "Okay, just eat your meal. Tomorrow I will send a team of guards to accompany you to the mountain."

Lu Zheng raised his head suddenly, surprised. "How do you know?"

Rong Zhen smiled lightly: "It's not that hard to guess. If you want my help, why don't you just say it directly? Why beat around the bush?"

Lu Zheng felt a little uncomfortable and said: "This... This kind of thing, it's better to win it by yourself."

Rong Zhen sighed and looked into his eyes: "You should know that I'm not the kind of person who would fight to the death regardless of other people's wishes. These things are just a piece of cake for me. I don't want you to take it as a heavy burden and let it affect your true feelings."

Lu Zheng was stunned.

Rong Zhen reached out and patted his head gently: "Eat quickly, it's getting cold."

"Hmm..." Lu Zheng came back to his senses and quickly lowered his head to eat. He didn't want Rong Zhen to notice the sudden blush on his face. Doing this is a foul, Your Highness the King of Chu! !
