It was late autumn again. When Rong Xi woke up in the morning, he saw the rain falling like a curtain under the eaves, and he couldn't help but smile.
"Where does Dalang's happiness come from?"
Chen Chuangu shook off the water stains on his umbrella and asked with a smile.
"It's raining, which is good." Rong Xi replied.
Chen Chuangu was puzzled, "Where does good come from?"
On rainy days, clothes get wet easily, shoes and socks get dirty easily due to muddy roads, which really ruins one's mood.
Rong Xi stretched out his hand to catch the raindrops. The water drops swayed in his palm for a few times and then disappeared between his fingers.
"Last year on a rainy night, Brother Chen and Sizhi stayed at Rong's house. I can still remember the scene vividly."
When Rong Xi first met Qin Sizhi, he only felt that this man had an extraordinary appearance, nothing else.
However, in just one year, he had fallen deeply in love with someone's tenderness and couldn't extricate himself, but he was willing to do it.
Chen Chuangu agreed with this and joked, "When I first met Dalang, he was twice as big as he is now. In just one year, he has become a handsome man."
He spoke from the bottom of his heart.
Rong Xi's skin color was originally extremely fair, and even after being scorched by the summer sun, it did not change at all.
The sky was hazy, and he was wearing a dark robe, which made his jade-like skin and picturesque features stand out even more.
"Thanks to Brother Chen's help..."
Chen Chuangu waved his hands quickly, "Da Lang, there's no need for us to be so formal. You've helped me a lot, so there's no need to mention the past."
"Haha," Rong Xilang laughed out loud, "I was just thinking, if it weren't for Brother Chen, Sizhi and I wouldn't have..."
He chuckled and didn't finish his words.
Chen Chuangu knew what he meant and said hurriedly, "It has nothing to do with appearance. Qin Sizhi has never cared about appearance."
Seeing the puzzled look on Rong Xi's face, he said, "You must not know that he cared about you very much when you were still fat. He was the one who asked Si Wen to investigate the matter of you bullying Si Wen. Otherwise, your grievances would not have been cleared so quickly."
Rong Xi's heart skipped a beat, "Really?"
"Why would I lie to you?" Chen Chuangu said solemnly, "Da Lang, he is with you because he likes your personality and talents, not anything else."
Rong Xi's face suddenly brightened, "Yes, I know."
His eyes were curved like a crescent moon, and he seemed extremely happy.
Qin Ke searched all over the grass to find the purse left by his biological mother. He washed it carefully and returned it to him after traveling thousands of miles.
Thinking of this, Rong Xi felt even more moved. Every little bit is filled with deep affection.
He just talked about appearance just joking with Chen Chuangu, but after Chen Chuangu's explanation, he felt that he liked Qin Ke even more.
"Da Lang, can you tell me how effective the medicine is?" Chen Chuangu suddenly asked ambiguously.
Rong Xi was confused, "What medicine?"
Seeing that his expression was not fake, Chen Chuangu was shocked, "Da Lang, you and Qin Sizhi haven't..."
"Chen Chuangu," Qin Ke's cold voice suddenly appeared, "If you have nothing to do, why not go and take a look at the leaves."
Ever since he last saw a microscope, Chen Chuangu would study it whenever he had nothing to do and was quite interested in it.
He was quite tactful. He smiled heartily, stopped disturbing the two of them, and walked along the corridor to the laboratory.
Rong Xi turned around, made eye contact with Qin Ke, and asked with a smile: "I was drunk last night, did I say any nonsense?"
The boy was extremely quiet and well-behaved after getting drunk, Qin Ke thought to himself, but replied, "Yes."
Rong Xi suddenly became interested, "What nonsense is this?"
"It's not nonsense," Qin Ke suddenly moved closer to him and said in a low voice, "It must be the truth spoken after drinking."
"What's the truth?" Rong Xi realized that he was teasing her and was joining in the performance.
Qin Ke put his lips close to his ear and whispered something. Rong Xi's face suddenly turned red and he blurted out, "Impossible!"
"Why not?"
Rong Xi suddenly laughed out loud and fought back: "Qin Sizhi, even if you are lying, I still like you very much."
Rong Dalang became more and more shameless, and he spoke love words without any shyness.
Qin Ke admitted defeat and said with a smile: "You didn't talk nonsense last night. I was lying."
The autumn rain was drizzling, and today was a day off, so the two had nothing to do and played chess in the study.
A year later, Rong Xi's chess skills have improved greatly. Unlike Qin Ke's strong and domineering style, his chess style appears gentle and reserved, but it hides murderous intent.
Even though Qin Ke had been through hundreds of battles, he often found it difficult to guess what the other party was doing. It was not until he was trapped and died that he realized that the hunters had set traps for him just a few dozen steps ago.
It is quite rare to find someone who can deceive him.
A person's chess style is like his personality. After spending a long time with Rong Xi, Qin Ke realized that Rong Dalang was not as gentle and harmless as he appeared. He has a bottom line in mind, and if anyone infringes upon it, he will fight back with all his might.
However, chess and reality are different after all. When playing chess, Rong Xi could kill Qin Ke without leaving a single piece of armor behind, but if he were in reality, it would be difficult for him to do so. Just like when faced with the person who broke into Rong's house last year, Rong Xi did not take his life.
But precisely because of this, Qin Ke admired it even more.
"You lose."
When the young man gave birth to a child, his indifferent features suddenly became lively and a little proud, which was completely different from how he looked in front of others.
Qin Ke sighed lightly and said jokingly: "Teach the apprentice and starve the master to death."
"How could that be?" Rong Xi pretended to be surprised and asked, "You called me your senior disciple that day, and you seemed to enjoy it."
"Lanzhi," Qin Ke turned his head away, tightly grasping the chess piece in his hand, not daring to look at him again, "Don't do this again."
Dalang loved to tease people more and more. If he had not had extraordinary self-control, he would have taken advantage of the young man long ago.
Rong Xi chuckled, and asked obediently, "Brother Chen just asked me about the efficacy of the medicine. Your Highness, can you help me solve this puzzle?"
Qin Ke's ears suddenly turned red and his long eyelashes trembled violently.
He was silent for a few breaths, then whispered, "My mother gave me the secret recipe of the palace. Chen Chuangu left earlier to prepare this medicine."
"Where is the secret medicine used? What are its effects?" Rong Xi asked with a smile.
It is also a kind of pleasure to appreciate someone's shy expression.
Qin Ke knew that he was teasing him, and thought he was naughty, so he turned the tables and said, "You will know in the future, there is no need to rush."
Rong Xi showed no shyness at all and said with a smile: "I wonder if the effect of this medicine will disappear after a few months."
"It can be guaranteed to remain unchanged for ten years." Qin Ke responded seriously.
Seeing that he kept turning his head away and didn't dare to look at him, Rong Xi finally felt guilty, so he picked up the chess pieces and said, "Another game?"
Qin Ke nodded, and the two continued to play chess in the rain.
However, in the next few games, Qin Ke's moves were extremely chaotic, and Rong Xi couldn't help but suspect that someone was distracted and no longer suitable for playing chess.
Qin Ke was upset. No matter how strong his willpower was, he couldn't resist Rong Xi's constant stirring of his heart.
He stood up suddenly, walked out of the study without saying a word, and even ignored his rain gear. He stepped into the yard and let the cold rain fall on his body, then disappeared from Rong Xi's sight.
Rong Xi: “…” His anger seemed to be getting bigger.
The next day the autumn rain stopped and the sky was blue and cloudless.
When Rong Xi and Qin Ke returned from prison, they saw Rong Mo squatting in front of the door of the new house, scratching on the ground with a branch, while Guo Yao beside him was watching him very seriously.
"Are you giving your third brother some special treatment?" Rong Xi leaned close to Qin Ke and whispered teasingly.
In school, Guo Yao often competed with Guo Zigui for the top spot.
She has a good talent for learning, is serious and hardworking, and has a very pure mind, so it is natural for her to achieve good results.
Fortunately, Guo Yao helped Rong Mo when he was sewing the cloth wings. From then on, Guo Yao assisted every time a new flight mold was made.
Both of them are taciturn, but when they are together, no one can break the atmosphere.
Qin Ke did not answer. He did not care what the others thought.
Rong Xi walked closer and saw the ground was covered with algorithm formulas. He couldn't help but smile. It turned out that Rong Mo was really giving him some special treatment.
The arithmetic courses in the school are still simple. Rong Mo has learned far more than the students. He teaches Guo Yao arithmetic and he does have the ability to do so.
Rong Xi's steps were very light, and the two of them were focused and had not noticed anyone approaching.
The arithmetic on the ground is extremely concise. If Guo Yao was not very smart, he would not understand what it meant.
Rong Mo wrote a question on a branch and waited for Guo Yao to answer it to check Guo Yao's learning results.
Guo Yao also answered using tree branches and got the answer.
The two of them did not say a word during the whole process, but they cooperated well and the teaching was successful.
Rong Xi was extremely pleased, so he took a step forward to attract the attention of the two people.
When the two heard the noise, they hurriedly stood up and turned around. Guo Yao saluted respectfully, and Rong Mo's eyes lit up slightly.
"The teaching is good and the learning is good." Rong Xi praised.
Both of them looked delighted.
Rong Mo took a piece of paper from his arms and handed it to Rong Xi, his eyes full of anticipation.
"Any progress?" Rong Xi took it and asked in surprise.
Since the success of the last flying mold, Rong Mo has been persevering in striving to make the flying mold go further.
He continues to make improvements and record detailed data to this day.
After reading it carefully, Rong Xi couldn't help but be shocked by Rong Mo's talent and tenacity. According to what was written on the ink paper, after continuous improvements, the flying mold could use the power of the wind to glide in the air for dozens of feet, which is about three hundred meters in later generations.
This is simply like a magical skill.
At the beginning, he only casually mentioned kite flying just to pique Rong Mo's interest. He never expected that he had such perseverance and talent.
I really found a treasure.
"Third brother, you have been researching for several months, do you know the reason?"
Upon hearing this, Rong Mo nodded and shook his head.
Rong Xi smiled and said, "From the records, it can be seen that the more perfect the curvature of the wing cross-section, the stronger its flying ability, right?"
Seeing the young man nod seriously, Rong Xi continued: "If you know why the wind is generated, you will know the principle of mold flight."
Qin Ke and Guo Yao both listened quietly and were stumped by what he said.
Why does wind arise? Nobody knows.
Rong Mo's eyes were filled with desire, he looked straight at Rong Xi, as if begging him to clear up his doubts.
"Come with me."
Rong Xi smiled and waved. Seeing Guo Yao hesitated and dared not enter, he said gently, "You come too."
The four of them entered the laboratory together, and Rong Xi took out a glass container with a very strange shape.
There is no lid, and there is a round hole on the bottom and one side wall of the vessel, which is about the length of a thumb.
He lit a candle, left it on the table, and asked, "Does the flame move?"
The doors and windows of the laboratory were closed, there was no wind inside, and the flames burned vertically naturally.
All three of them shook their heads.
Rong Xi smiled slightly, then covered the candle with a glass container with the round hole at the bottom facing upwards. He took an iron pipe as a chimney and connected it vertically to the round hole, with the candle flame just aimed at the round hole.
"Watch the movement of the flame carefully." Rong Xi gave an order, and the three of them looked intently, not daring to blink.
At this time, the circular hole in the side wall is located at the right end and the candle is on the left.
In a moment, Guo Yao's eyes lit up, "It's moving!"
Qin Ke couldn't help but look at Rong Xi, asking with his eyes what the reason was.
There was clearly no wind in the room, so why did the candle flame lean to the left?
All six eyes showed anticipation, so Rong Xi stopped keeping them waiting and explained in a serious tone, "The candle burns and generates heat, which creates a temperature difference between the inside and outside of the glass, generating wind. The wind enters from the right hole and blows the candle flame."
"Why does temperature difference generate wind?" Qin Ke asked.
This question involves very broad principles, and he couldn't explain it clearly at the moment.
Rong Xi thought for a few moments and could only jokingly say, "Perhaps the low-temperature side wants to seek warmth, so it invades the high-temperature side. The greater the temperature difference, the more aggressive the low-temperature side will be."
Qin Ke couldn't help laughing.
He knew the reason was not simple, but he stopped asking and said gently: "Since wind power is generated here, what is the connection with the shape of the flight mold wing surface?"
"Flow rate." Rong Xi explained, "When the flame burns, the air around it flees in panic, and the air on the right side chases after it, and the same is true for the flying wings."
"When the flow velocity on a curved surface is higher than that on a flat surface, it will generate a lifting force."
Rong Xi's answer was extremely difficult, and he had no way of explaining many of the terms and principles used in later generations.
Rong Mo's eyes became more and more fiery. He seemed to understand, but also seemed to understand only half of it. However, he was still immersed in the wonderful principle, and his thoughts flew away.
Rong Xi was secretly sweating in his heart. The principles of all things were only discovered after many scholars had studied them thousands of times. For the people of Wei, it was really too advanced.
"Well, let's go have dinner."
Qin Ke noticed that he was in a difficult mood, so he spoke in a gentle voice.
He shouldn't have asked too many questions and put Lan Zhi in an awkward position.
Rong Xi was about to respond when he saw Rong Mo suddenly running out, not knowing what he was going to do.
Guo Yaowei bowed and left the laboratory.
During dinner, Rong Xi was distracted and had no appetite. He suddenly realized that he had been quite naive before.
He is too impatient.
Seeing that he had only eaten half a bowl, Qin Ke was worried and said, "I am too clumsy to understand what you are thinking."
He blamed himself so much that Rong Xidun felt guilty and couldn't help but sigh, "It's not your fault. I'm not good at teaching and I was too aggressive."
In fact, it was because he was too lonely.
Even in later times, he had nothing to say to many people.
For many topics, if two people are not on the same level, it will be difficult to continue the communication.
He often felt a sense of powerlessness.
"Don't worry, Rong Mo has good talent and will understand you in time." Qin Ke comforted.
Rong Xi hugged him fiercely, pressed his forehead against the man's shoulder, and said in a muffled voice: "You are good enough."
It was so good that he couldn't bear to be greedy anymore.
Although there is a gap in their cognition, Qin Ke has been silently trying to understand him and help him realize those ideas that seem ridiculous to the world.
He was too demanding.
"But I want to understand you." Qin Ke lowered his head and kissed his temple.
Rong Dalang didn't know how fiery his eyes were and how excited his tone was when he talked with Cheng Hao, Rong Mo and others.
Because Cheng Hao and Rong Mo understood what he was talking about.
When Rong Xi heard this, his eyes suddenly became moist.
When he was confused and lonely, he didn't know that someone was approaching him cautiously, trying hard to understand him, and blaming himself for not being able to understand.
"Qin Sizhi, it's my fault."
He walked too fast and too hurriedly, without paying attention to the fact that Qin Ke was staggering forward.
Qin Ke patted his back gently, "No need to apologize to me, I just want you to be happy, don't force anything, you and I can still live for decades, don't be impatient."
"I don't understand. You can teach me and I will learn slowly." He continued softly, "One day, I will catch up with you and stand shoulder to shoulder with you."
Rong Xi suddenly raised his head, his eyes slightly red, his expression was both happy and self-blaming, "Sizhi, I'm a little tired."
Because of self-doubt, I feel tired.
Qin Ke picked him up gently and said, "Then take a few days' rest."
Over the past year, Rong Xi has indeed been too tense.
Qin Ke was well aware of Rong Xi's ambition. He was willing to help him realize it, but he did not want Rong Xi to suffer.
"You'll accompany me?"
"I'll accompany you."
