It's not a perfect power system, but it's a complete system, at least more complete than the simple steam engine that passed by. There is a bellows, there is a stove, the stove is made of bricks, and the outlet at the other end is a ceramic piston, the piston is connected to the connecting rod, and at the end of the connecting rod is a crank shaft, but the crank shaft is not connected to the large waterwheel outside, and it hangs in the air.

Passing by picked up the crank shaft and looked at the waterwheel system very closely. Zhou Chongyang followed him, stretched out his hand to shake the waterwheel, and it took a lot of effort to push the waterwheel to spin, and asked suspiciously, "What is this?"

Ping Ah Si replied with some embarrassment: "I don't know. But Ah Huo said that when the fire burns, it can push this thing. As he spoke, he pointed to the part that Zhou Chongyang was fiddling with, and said, "This little thing can step on the waterwheel instead of us, but he has been fiddling with it for several years, and he has stepped on it, but it ......."

"But how?"

Ping Ah Si was a little embarrassed, didn't know what to say, compared for a long time, and said, "We don't know either." Ah Huo said it couldn't be used. So, everyone still needs to step on it. Xiaohu, go, call Brother Ah Huo. In the last sentence, he said to a child who was watching the excitement next to him.

The child let out an "oops" and ran away. Passing by and listening and watching, it seems that this Ah Huo did not succeed, so he gave up halfway. He thought carefully about the fact that the fire would produce hot gas, and someone later used it to make a hot air balloon, which was the precursor of the airplane. But with fire as a motive force -

"I'll go! it's actually an internal combustion engine!" he slapped his thigh and scolded. He didn't study physics and mechanics, and he could remember the steam engine because he was too famous, but the later internal combustion engine was limited to junior high school, and he would have been thrown into the corner where he didn't know it, and if it weren't for this weird device reminder, he wouldn't have remembered that there was such a thing. It's more high-end than the steam engine, isn't it?

Passing by, he wiped his face, turned around and asked, "Who is Ah Huo?"

Ping Ah Si replied: "Ah Huo is a young man I picked up on the road a few years ago. He was burned beyond recognition, and the people of the village were afraid of him. I brought him back. Master Lu, does this thing work?"

"Useful, of course useful. But it will take some time. "He wants to write a letter to Chen Jialuo, this person named Ah Huo is definitely a talent, and he must be cultivated well.

"Fourth Uncle......" A very rough voice sounded behind him. When I turned around and saw someone coming, I was startled, and I took a few steps back very rudely.

This is such an unrecognizable person. From head to face to neck, it was not in the coat he was wearing, and there was no skin intact, it was all hideous red flesh. He had no eyebrows, only a small part of his ears and nose, and his lips turned up, so that he could not even cover his teeth. He was wearing a coat, sweaty, and dusty, which added to the horror. Seeing that someone was frightened by himself, he didn't react much, just turned sideways slightly, and lowered his hand to face Ping Ah Si.

"This ...... I'm really sorry......" Passing by, he wanted to make amends quickly with a very sinful heart, and stepped forward to hold Ah Huo's hand and said, "I...... Too surprised, didn't mean anything else. ”

Ah Huo's hands are also the same as his face. What kind of fire is it that burns people like this? Because they have been burned by fire, they know the energy of fire?

"It's okay, it's me who's too scary. Seeing that he shook hands with him instead of fear, Ah Huo was also warm in his heart, but he uncomfortably retracted his hand and wiped it on his coat. He had just come from the threshing floor, and his hands were sweaty, dusty, and dirty.

After Ping Ah Si introduced the people passing by again, he said, "Ah Huo, Lu Ye is very interested in this, I can't say anything." ”

Ah Huo's eyes, which didn't even have full eyelids, suddenly lit up, and asked, "What does Master Lu want to know?"

After talking to Ah Huo, passing by learned that he was from the north. Once there was a fire in the house, he locked himself in the house to study, and when he realized it, he wanted to rush out, but as soon as he opened the door, he was blown out by the anger of the shop, but he also picked up a life.

"That scene is so impressive, why is the fire so powerful? The fourth uncle saved me, and I couldn't help with all my limbs, so I pondered this problem. He put the crank shaft on the waterwheel with his hand, pulled the connecting rod, and drove the crank shaft to rotate, and said very regretfully: "Unfortunately, I still can't figure it out." ”

I can't figure it out, no one understands, and I need to make ends meet. Ah Huo couldn't let himself be immersed in it, so he had to give up.

Passing by, I understand that Newton and Galileo, those who think about nature, belong to those who have time to think when they have eaten and have nothing to do. He didn't know if there was really a fire in the real history, but after having these advanced ideas, he finally had to give up because of loneliness and life pressure. But since he has encountered it, there is no reason to let it go. He couldn't help but solve Ah Huo's doubts, but he could help him find some companions and provide him with a worry-free environment, so that he could think about how to make his internal combustion engine waterwheel spin.

What will become of this Qing Dynasty in this turn? He will wait and see.

When he passed by, he wrote a letter and asked Zhou Chongyang to send it to Chen Jialuo, asking him to come here in person to invite someone in person, and then ask Ping Ah Si about Hu Yidao's relics and Hu Fei's father-killing enemy.

"Fourth uncle, Brother Hu's martial arts have few opponents now, even if he is a powerful enemy, he has the ability to take revenge. You don't have to worry about anything anymore. ”

The enemy is Miao Renfeng, who is invincible all over the world, Ping Ah Si has seen him compete with Hu Yidao, and he is afraid that Hu Fei will not practice well and only take revenge with his blood, and in the end, not only can he not take revenge, but also gave his life in vain, so he concealed it once. Now that Hu Fei has grown up and come back, and he has followed so many amazing companions, he is also relieved.

Because the matter of the relics was too solemn, Ping Ah Si had to tell Hu Fei alone. In Hu Fei's heart, Cheng Lingsu is like her own sister, and there is no reason to reject her. The treasures related to his father's relics were brought up by passing by, and now that Zhou Chongyang is not there, if he only stays with Shi Wanyi and the three of them, he is afraid that if something happens. Therefore, he did not shy away from anything, and the group followed.

Ping Ah Si took them to an inner hall, pushed open the door, and there was a table in the center of the room, the table was covered with white cloth, lit incense table, and offered a spiritual tablet, which read "The spiritual position of the Liaodong hero Hu Gong and his wife".

Hu Fei fell to his knees with a puff and called, "Daddy." Ping Ah Si couldn't help but burst into tears, and said tremblingly: "Master Hu and his wife have spirits in the sky, and when they see the little master grow up, they must be smiling at Jiuquan." ”

Hu Fei was in tears, and Sen Ran said: "Fourth uncle, it was the golden-faced Buddha and Miao Renfeng who killed my father, didn't you?"

"Yes!" Ping Ah Si also spitted fire in his eyes, and said angrily, "It's not just him, it's not just him who killed Uncle Hu!"

As soon as these words came out, in addition to passing by and knowing the inside story early, Shi Wanyi and others had nothing to do with themselves, but Hu Fei and Cheng Lingsu were stunned, gritted their teeth and said, "Who else?"

"It's the thief Yamaki we saw at Fort Merchant's a few years ago, when he was just a bruiser doctor. There is also a large group of Jianghu people with Miao Renfeng, they are all murderers who killed your Uncle Hu!"

Ping Ah Si immediately carefully explained what he saw at the beginning, the cause and result of the accident of Hu Yidao and his wife in the Cangzhou Inn, from beginning to end. When talking about Hu Yidao's heroism, Hu Fei couldn't help but applaud; when he talked about asking Yan Ji to deliver the letter, Cheng Lingsu shouted "terrible"; and said that Hu and Miao were not full of leisurely fascination and hatred for each other. Even Shi Wanyi and the others were fascinated by it; and when it came to Yan Ji smearing poison on the blades of the two, Hu Fei gritted his teeth and wanted to spew fire, and Cheng Lingsu tightened the corners of his clothes; Finally, when it came to Hu Yi's death with a poisonous knife, Mrs. Hu killed herself with a knife, Hu Fei's tears fell like rain, and Cheng Lingsu held his arm and comforted him silently.

Passing by, I was a little bored listening to this well-known story, and I patiently did not correct Ping Ah Si's occasional one-sided words. After all, Ping Ah Si only knew everything that happened in the inn, but he didn't know anything about the reasons behind it and what happened outside the inn. But when he heard this, seeing their eyes full of sorrow and sadness, especially Hu Fei's expression like an outcast, he couldn't help but feel a tug in his heart, thinking of his parents. I don't know if he somehow crossed into the world in this book, and whether there is a person like him in reality. If not, will the parents be sad? Even if there is, his parents can be comforted, but they don't know that he is here alone, and he is lonely and desolate.

He was sighing silently when a doubt suddenly emerged. He stared at the spiritual position of Hu Yidao and his wife, thinking very hard and hard, and then suddenly thought of a question.

What do my parents look like?
