Li Ke lay on the bed, tossing and turning, unable to sleep.
His hand had been wrapped with a strip of cloth. Sun Simiao, the king of medicine, had wrapped it for him personally. The best wound medicine was used in it. At this moment, he felt a burning pain, as if someone had cut it out bit by bit with a knife.
My whole body aches, as if my body is no longer my own.
Li Ke swore that this was the most difficult day he had experienced in the more than ten years since he was born.
But when I thought about it, this was Du He's test.
He gritted his teeth and said, "Du He, I will never give up."
…
It's still dark.
Du He went to the laboratory to check out the situation. Yuan Qingfeng mentioned yesterday when he came to ask for advice that the amount of electricity discharged by the big sulfur ball seemed to be less than before. He planned to go and find out what went wrong.
Holding a lantern, Du He came to the laboratory entrance of the R&D center.
But I found that the laboratory door was unlocked.
Du He muttered: "Isn't the breeze blowing a little bit lately? The door is not even locked..."
He opened the door gently and was about to walk in.
Suddenly, a white shadow appeared in front of him.
Even though Du He had a good psychological quality, he was also shocked.
Taking a closer look, I saw an unkempt guy appearing in front of me.
It was Li Ke, the king of Shu.
Li Ke's hair was messy, his eyes were red and swollen, his face was pale, and his lips were chapped. He looked miserable.
Du He said in surprise: "Damn, you...you didn't stay in this laboratory all night, right?"
Li Ke shook his head: "No, I can't sleep. I want to come here to have a look. I have already figured it out..."
"What do you understand?"
Li Ke said seriously: "The principle of this motor, I don't know what electricity is, is it something like a fire? But I know that this motor relies on friction to produce electricity. I heard Qingfeng say this
Sulfur balls. Rubbing sulfur balls with animal skins will generate electricity. Rubbing them with silk can also work, but the effect is not as good as animal skins. Moreover, animal skins are cheap and silk is expensive... It seems that this big sulfur ball can store electricity, but it will not be used after it is discharged.
But I didn’t understand what the use of this thing is. Qingfeng said it can be used to study thunder and lightning, but what is the use of thunder and lightning? I thought about it for a long time, and finally found that it has a function. If thunder is discharge, then we are
Isn't it possible to put a very tall copper or iron object on the tower, and then use copper wire to lead it underground, so that the tower will not be struck by lightning? Du He, this must be feasible, right?
"
Li Ke is very excited now.
My mind is full of questions.
He is like a child who has fallen into a treasure house and finds everything new and strange.
Du He was stunned.
Isn’t this the original lightning rod?
Li Ke actually thought of it?
Du He asked: "Did Qingfeng tell you this?"
"No, I thought of it myself! I remembered the Tai Chi Hall. There are copper things on the roof of the Tai Chi Hall. I asked the craftsmen why they put copper things here. The craftsmen said they were for sacrifice to heaven.
To avoid being struck by lightning, they don’t understand science at all. This is to trigger thunder, not to sacrifice to heaven at all. This is science..." Li Ke became more and more excited as he spoke.
Du He looked at Li Ke's miserable appearance and said, "Okay, you kid is worth training, but looking at you like this, I can't help you today. You go back and rest. Even if you pass this first question,
Now, when you recover, come see me again."
"good!"
Li Ke turned around and left excitedly.
…
Du He originally thought that Li Ke could calm down for a few days.
Unexpectedly, when Du He got up early the next morning, he saw Li Ke standing in the yard, staring at a mini waterwheel in the yard, fascinated.
Li Ke saw Du He, turned around, and said with a smile: "Du He, I have been here a long time ago. I knew you were sleeping, so I didn't disturb you!"
"What's the matter?"
Li Ke waved his hands wrapped in white cloth and said, "I'm here to become a disciple. Please give me the second question."
Du He took a closer look and saw that Li Ke's complexion was better than yesterday, but his face was still pale and there was still medicine on his hands, a typical sign of an injury.
But seeing his interest and expectation, Du He didn't know what to say, so he said: "Okay, for the second question, you first go to Taoyuanju to learn how to build a fireplace with Lu Yuan, and I'll give you two questions.
If you can learn it in two days, then there is no need to ask the third question, I will accept you as my disciple directly."
"Okay, Du He, just wait, I won't let you down." Li Ke said with confidence.
…
Two days later.
Li Ke's performance made Du He very satisfied.
This kid is not only able to endure hardships and is not afraid of tiredness, but he is also very smart. It only took one day to learn the principles of fireplace heating. With Lu Yuan's help, he also formed a study note with drawings.
Appropriate.
Du He decided to accept this disciple.
Du He put away Li Ke's study notes and said: "King Shu, according to our agreement, now that you have completed the two tests, you can become my registered disciple."
"Named disciple? Not a formal disciple?" Li Ke asked curiously.
Du He nodded: "Who gave you the status of a prince? I already have three disciples. If you want to be my official disciple, you can only be the fourth. Are you willing? If you are willing, His Majesty is not willing yet.
Okay, this matter has been decided."
In fact, Du He still resisted getting too close to the royal family.
In real history, Li Ke was not an honest guy. He was involved in Fang Yiai's rebellion and died miserably.
When His Majesty is still young and powerful, the one Du He is looking for is His Majesty Li Er, and everyone else is a scumbag.
Therefore, being a registered disciple was Du He's limit.
Hearing this, Li Ke could only nod helplessly, and then asked: "Teacher, I heard from Qingfeng that there is a ceremony for apprenticeship, which is very solemn. Why is it not here with me?"
Du He stood in the yard, a gust of wind blew, and the only dead leaves on the trees fell lightly.
He said in a deep voice: "What is the difference between apprenticeship ceremony and apprenticeship ceremony? I have said that the Tao is simple. The real apprenticeship ceremony is inner obedience. It is internalized in the heart and externalized in the heart. There is no need to care about those etiquette."
Li Ke instantly felt that Du He was too tall.
Then I heard Du He say: "Of course, the apprenticeship ceremony can be simplified, but the cost cannot be saved. You must pay the apprenticeship fee today, a total of five thousand guan."
Li Ke: "..."
…
The seventh year of Zhenguan, the fourteenth day of the winter month.
Li Ke, the king of Shu, became Du He's apprentice and became Du He's registered disciple. He also paid 5,000 coins to become his disciple.
I don’t know how the news spread. In just a few days, it spread throughout Chang’an City.
The people were talking a lot, and they all felt that Du He was so powerful that even the princes worshiped him as their disciples. It was not new for a prince to become a disciple. Which prince did not have many teachers, but Du He was different. This boy was only seventeen years old, and he was better than the King of Shu.
