The little train clattered along the wooden tracks, and it couldn't stop at all, as if it had eaten Xuanmai.

"Whoa, whoa, whoa." The students, including several gentlemen, sat on the stools, staring at the trotting train in the square with their mouths wide open and their eyes wide open, not knowing what the thing in front of them was, let alone how the monster was running.

"We already knew that my brother had made this little train last year, and he had run it several times at home." Fang Yuan said proudly to his classmates beside him.

"Brother Jing is the most troubled, we have met several times before, but he just doesn't let us play." Lizhi also said to her classmates beside her.

"You don't know how this thing in front of us is going to run on its own, right? Actually, this is an experiment I did when I was teaching you before, and then I made this thing, relying entirely on charcoal and water, to drive this little train forward, steam to generate power, do you know? Fang Jing shouted loudly to the students and gentlemen sitting there, and the voice of the small train was a little too loud.

"Mr. Fang, we know about this steam experiment you did before, but can steam alone push this thing to run all the time? Forgive me for my ignorance, can I ask Mr. Fang to explain the knowledge in this? Yu Li stood up from the stool and asked Fang Jing loudly.

"Yes, Mr. Fang, can you explain to us how this steam experiment can propel this thing to run? We haven't understood much about the knowledge, so please let Mr. Fang know. Qin Shu also stood up and asked loudly.

The soldiers not far away, as well as the villagers of Fangjia Village, stretched out their heads, stared at the small train in the square, the horror in their eyes naturally appeared on their faces, their ears erected, waiting for Fang Jing to answer.

"This steam experiment, you have also seen me do, the heat generated by steam is very large, I believe you also know, it is hotter than boiling water, the kinetic energy generated by steam, through some devices, and then drive the wheels of this small train, you can make this small train run forward, of course, the locomotive made of steel, and the furnace that boils water, must be sealed to prevent this steam from leaking, I say this, can you understand?" Fang Jing shouted and explained to everyone.

"I see, it just takes some special device to push the steam into the device to make this thing run." Yu Li suddenly realized, and after listening to Fang Jing's words, he finally understood why this little train could run on its own.

"I've been making this little train since last year, and I've experimented with it many times at home, and if the charcoal can be supplied and the water can be supplied, then the little train can run until it is damaged." Fang Jing had never experimented with what the ultimate limit of this little train was, let alone how long it could run, maybe a few days, maybe a few months, but who knows.

"Mr. Fang, may I ask, what is the use of this little train?" Zhang Ze had a lot of doubts in his heart, he was originally a student of Confucianism, so he naturally didn't have much sense of identity with these strange and obscene skills, but he just came to the Fang Family School and listened to some of Fang Jing's classes, but he also began to change his concept.

"Mr. Zhang's question is good, then I will ask you to take a look at it, Chen Dachu, Li Ju (Xiaoshu), you come up and sit in this carriage." Fang Jing shouted loudly to Da Chu and Xiao Shu, and then ran close to the little train and pulled the valve, causing the little train to slow down and stop.

After the two climbed into the two carriages, Fang Jing told the two to grasp the edge of the carriage, and Fang Jing opened the valve again, only because of the increased weight this time, which made the operation a little slower.

"Nourish...... Click...... Bang dang...... "Clang......" The little train quietly pulled down the acceleration gear again, and officially trotted along the track.

"Wow, wow, wow, I'm going to sit too, I'm going to sit too." Fang Yuan and Lizhi were like stars, it turned out that the little train made by Fang Jing could still sit on people, and now it made the little babies in the family speechless with excitement.

"This ...... The soldiers and villagers standing not far away from this ...... also began to have stars in their eyes, and they didn't know how to describe it at all, it turned out that this monster could still sit on people.

"Quiet." Fang Jing shouted loudly to everyone.

"Let's see, this small train is not big, but it can still carry Chen Dachu and Li Ju on their backs, and the weight of the two is added together, and it is also one hundred and fifty pounds. Or maybe you want to ship some goods? Fang Jing continued to explain to those present that this was a powerful witness.

"Mr. Fang, with the little train in front of you, it's still too small, after all, it's not of much use." Zhang Ze opened his mouth and shouted at Fang Jing.

"Mr. Zhang, everyone, maybe you just see that this little train is still too small, so have you ever thought about building a locomotive as big as a house? How many things and how many people can they carry? And this train only needs to be fed with water and charcoal, and does not need to be fed like cows and horses, and if there is this track, he can run all the way, from east to west, and that is not a dream. Fang Jing shouted at them, hoping that everyone could open their minds and think about it.

Everyone was quiet and didn't say anything more, the students stared at the small train, and the big chu and the little tree in the carriage, while the three gentlemen, the soldiers, and the villagers, each had their own ideas.

The whole afternoon of the little train experiment has not stopped, one by one the students are rushing to sit on it and run once, so as to experience the flying effect brought by this little train, maybe this little train can become the most fun toy in their minds.

After class, Fang Jing didn't take back the little train and went home, it was placed in the square for the time being, and waited until the evening, until there was no charcoal fire, it stopped, Fang Jing held the small train and other things, and put them in a classroom in the school to store, and when they were free in the future, they could also be placed in this square for the little babies to play, anyway, the function of the little train fire also needs to be used to open the brains of the little babies, as well as their exploration ability.

"Brother, I still want to sit." Fang Yuan followed behind Fang Jing and complained to Fang Jing.

"Brother Jing, we still have to play, you didn't let us play before." Lizhen took two little female bodyguards to protest towards Fang Jing.

"Let's play again in a few days, you can only play once a week, you have to go to class when you should go to class, go home on vacation, how can you play this little train every day, go, go home for dinner, I don't know if my aunt has made dinner." Fang Jing took the little baby at home and began to walk home.

Seven or eight days later, Fang Jing was working as an old lady at home, and at this time, in the big banyan tree camp, Wang Yanren's mother had just been picked up.

Wang Yanren looked at his skinny mother on the bed frame with distressed eyes, this illness has tormented his mother for nearly a year, from a rich old woman, to a skinny patient, Wang Yanren as a son, but can not share the pain for his mother, his heart is extremely sad.

"Big brother, you wrote to bring your mother over, what should I do now? What about the miracle doctor? Please come and heal my mother. Wang Yanren's second brother Wang Zhongren was so anxious that he shouted loudly to Wang Yanren as soon as he arrived at the camp, and even his little sister Wang Chuyu, who was standing beside him, was also anxious.

"Second brother, little sister, don't worry, when your mother arrives in Fangjia Village, then you will be saved, I will go and ask my husband to come over, and you will take good care of your mother." Of course, Wang Yanren hopes that his mother can get better quickly, but as the eldest brother, things still have to be in order, and besides, the family has just arrived, so the family has to settle down.

"Sir." After Wang Yanren left the camp, he quickly ran to Fang Jing's house, but fortunately, Fang Jing was working as an old lady at the gate of his home.

"What's wrong? Something? Fang Jing was lying on the recliner without opening his eyes, and when he heard someone running quickly, he only opened his eyes slightly and saw Wang Yanren, and continued to close his eyes and pretend to sleep.

"Sir, my mother has taken it, and please ask my mother to save me." Wang Yanren made a big salute to Fang Jing and waited for Fang Jing's reply.

"Then let's go check it out." Fang Jing opened his eyes and looked at Wang Yanren who was bowing, before he stood up and spoke.

Fang Jing raised his legs and walked towards the big banyan tree, not in a hurry or slow, Wang Yanren followed behind, wanting to urge Fang Jing to go faster, but he didn't dare, so he had to follow Fang Jing's steps.

Coming to the gate of the camp, Fang Jing took a casual look, and then stepped into the camp, this can be regarded as Fang Jing's first time entering the camp, he had never entered before, for Fang Jing, the military camp is sacred, so for a long time, he never thought of entering this camp to see, this time, it is also a special case.

"This way, sir." Wang Yanren walked in front at this time to lead Fang Jing.

"Second brother, little sister, I invited Mr. here, don't talk too much, just listen to Mr." As soon as he entered a residence, Wang Yanren told his second brother and younger sister to get up.

"Wang Yanren, go and call the doctors and doctors in the army to come over." Fang Jing looked at the old woman on the bed, observed it casually, and shouted at Wang Yanren.

Wang Yanren ran away from his residence, and after a while, a doctor and two military doctors came, and the military doctors were also known to Fang Jing, and the doctor came later, so naturally he didn't know each other.

"The three of you will see what Mrs. Wang's illness is, it is best to diagnose it clearly, and I will watch from the side." Fang Jing said to the doctor and the military doctor.

said that Fang Jing didn't know how to see a doctor, and called this doctor and military doctor to come over for diagnosis and treatment, just to let them diagnose what kind of disease this old woman had, so that he could use medicine or surgery according to the situation, in fact, Fang Jing also played a drum in his heart, if he killed someone, his reputation would be ruined by half.

After hearing this, the doctor and the military doctor quickly checked the pulse of the old woman on the bed, and asked Wang Yanren for the doctor's medical examination book from the past.

"Big brother, why does this miracle doctor look so young? Big brother, you won't be deceived, will you? Wang Yanren's second brother looked at Fang Jing and asked Wang Yanren softly.

"Big brother, I also think that you may have been deceived, we have to go to Chang'an quickly and find a famous doctor to treat my mother." Wang Yanren's younger sister Wang Chuyu also agrees with her second brother Wang Zhongren's statement.

"You don't have to say much, it's not easy to ask Mr. to help my mother heal, if Mr. doesn't treat my mother, it is estimated that it will be useless to go to Chang'an, don't say it again." After listening to the words of his second brother and sister, Wang Yanren was very angry and stopped the two of them sharply, but Fang Jing listened to it on the side and didn't care.

"Sir, it's an intestinal carbuncle, and the time is not short, fortunately, there are many doctors who use medicine to suppress it, otherwise this old woman wouldn't be able to last so long." A quarter of an hour later, the doctor finished his examination and opened his mouth to Fang Jingshu.

"Sir, it's a carbuncle." Military doctors Liu Feng and Liu Pei also confirmed to Fang Jing at the same time.

"Okay, I know, the doctor can go back, you two stay, Wang Yanren, be sure to clean this place for me today, cover it with a dry cloth boiled in boiling water, in addition, your mother's bed frame should also be replaced with a very clean one, the two military doctors will tell you how to do it, and come back tomorrow for treatment." Fang Jing opened his mouth to give a few orders, and then raised his legs and walked out of the camp to go home, leaving the two military doctors to start lining up.
