From that day on, Qu Lian and Yan Changge lived in the old house. This old house, which was carefully decorated by their grandfather, has a retro feel and modern facilities.

The old house is very large and is divided into two courtyards, the east and west. The east courtyard has been renovated, but the architecture has an ancient style, and the living is no different from the modern one. You can often see refrigerators, washing machines and other household appliances placed in the antique houses. The combination of ancient and modern times looks particularly interesting. The west courtyard retains the original ancient architecture and has not been renovated. According to Qu Yi's design, everyone usually lives in the east courtyard, but when the children of the Qu family need to practice martial arts, cultivate their character and patience, they will live in the west courtyard for a period of time. Everything needs to be done by themselves, even eating has to be done by chopping wood by themselves.

Qu Lian discovered that Yan Changge liked the old house very much. He often looked at the old house with a look of... a close friend, and sometimes muttered to himself at the beams and pillars of the east courtyard, which made Qu Lian very puzzled.

"You seem to like this house very much?" Qu Lian asked suddenly.

Yan Changge smiled and said, "That's right, I think this house is very similar to me."

Qu Lian: "...Why do you think an inorganic building is similar to your organic structure? Please give me a scientific explanation."

Under Yan Changge's training, Qu Lian would unconsciously speak with scientific rigor.

Yan Changge said: "Of course, it is not similar in terms of atoms and molecules, but... a similarity in feeling. It and I both come from the ancient times. After entering the modern society, we gradually removed the dross and retained the essence. While retaining the advantages of the ancient times, we also absorbed the progress of modern times. We are neither ancient nor modern, but a combination of the two, representing the fusion of two eras."

When he said this, Qu Lian felt a sense of distance from him. This person was clearly in front of him, but he seemed very far away from him, close in front of him but out of reach. They were standing together, but Qu Lian felt that Yan Changge did not seem to belong to this world... no, he did not belong to the human world, as if he was the same kind as the pillars in front of him and the shadow in the basement.

Qu Lian didn't have that much of the melancholy and sad literary air. He felt that Yan Changge was far away, so he hugged Yan Changge's waist from behind without hesitation and said, "What do you mean by the fusion of two eras? The pillars from the Song Dynasty have long been rotten and replaced countless times. This beam was replaced by my grandfather more than 30 years ago. It is covered with wood veneer on the outside and is full of steel bars and cement inside. It is not an ancient thing at all. And you, you just didn't understand the knowledge of modern society before, but now you have learned to abuse us mentally every day by relying on your academic tyrant status. When it comes to math, physics and chemistry, you are more fluent than university professors. Tell me, how are you like this pillar?"

Yan Changge was originally worried about what to do with the calamity tomorrow morning. After seeing the renovated East Courtyard, he recalled the little things in his human life for the past six months and felt a little bit touched. He knew that this faint sadness was actually sensitively detected by Qu Lian, a careless guy. Qu Lian was born rich. Even though his parents died in a disaster when he was young, his uncle took good care of him. Such a child who was raised in such a way never cared about the feelings of the people around him. Yan Changge was introverted and rarely showed his emotions. Unexpectedly, the careless Qu Lian could always feel his emotions.

Only if you care about someone and keep your eyes on him/her all the time, can you feel it.

Thinking of this, Yan Changge's sword felt warm in his heart. It seemed to have returned to the time when it was still the black iron from outer space. He had no intention of being forged into a weapon like ordinary iron in the human world, standing still in the flames. However, when the hot blood merged into the flames, his heart softened all of a sudden, slowly began to melt, and began to transform according to the will of the blood master.

He was born out of the expectations of two swordsmiths. He has experienced countless lives and deaths over the past two thousand years, but what he can't stand the most is the expectations of the sword masters.

When the sword master holds the hilt of his sword expectantly, he will respond to the sword master's expectations and unleash his power as an ancient divine weapon, making him invincible.

Now, he could clearly feel Qu Lian's expectation that he could be with him forever. Qu Lian did not desire to be with Yan Changge for the rest of his life. He just wanted to be with Yan Changge for the rest of his life. It was that simple.

However, for the first time, Yan Changge was unable to respond to his expectations.

Feeling that Yan Changge's usually steady palm was actually trembling slightly, Qu Lian grabbed Yan Changge's hand from behind and asked, "What's wrong with you recently? It seems that you always seem to be worried after returning from the reality show recording."

Yan Changge turned around and said nothing.

"Can't you tell me?" Qu Lian looked at Yan Changge with a sad look in his eyes. Although he tried hard to catch him, he still felt that this person was getting farther and farther away.

"I..." Yan Changge was having a hard time speaking, but he didn't know where to start. It was too embarrassing to tell his lover that he was a sword, but facing Qu Lian's eyes, a responsible person like Yan Changge couldn't just disappear without saying anything.

Qu Lian lost his parents and brother in two major disasters at the age of five and fifteen. If he loses his lover again in this disaster at the age of twenty-five, will he still be as strong as he is now?

No matter what, even if he concealed his true identity, he should give Qu Lian an explanation. He can't just disappear without saying a word.

Yan Changge did not hesitate for too long. After all, he was such a straightforward person. He held Qu Lian's hand tightly and said solemnly, "I am going to survive the tribulation."

"Cross, cross the tribulation?" Although Qu Lian was shocked, he did not show any doubt. After all, everything Yan Changge showed before did not seem like an ordinary martial arts master. It was more like he was a cultivator. "Are those things about cultivation written in novels true?"

Yan Changge nodded and said, "There were some in the past, but now... I'm afraid I'm the only cultivator left in this world. When science replaced superstition and the spiritual energy of heaven and earth became energy for the world, there were fewer and fewer cultivators. And I... I'm probably a special case. I focus on scientific cultivation and found a new way to absorb electrical energy."

"Then by overcoming the tribulation, are you going to ascend to heaven?" Qu Lian had not read many novels and did not know that one had to overcome the tribulation at every stage of cultivation. He thought that as long as one overcame the tribulation, one would ascend to heaven.

Yan Changge pinched his face and laughed softly, "It's not that easy to ascend. I'm just an ordinary cultivator who hasn't even formed a golden elixir. I can only see a little bit of the path of cultivation. I'm still a long way from achieving the right result."

"Is it dangerous?" Qu Lian's mind was in a mess. He had many questions he wanted to ask, but there was always only one most important question.

Whether it is ascension or danger, it means that Yan Changge is leaving him.

Yan Changge looked at his concerned eyes, reached out his hand to cover his eyes, put Qu Lian in darkness, lowered his head, and gently kissed his lips.

It was a light but lingering kiss, without any fierce lip-to-lip entanglement, but like a sweet potato wrapped in sugar water, no matter how many times they separated, they would stick together again. It was as if they were originally one and could not be separated.

After the long kiss ended, Qu Lian heard a word that made him despair in the darkness -

"have."

"How dangerous is it?" He helplessly grabbed Yan Changge's collar, hoping that he could tell him confidently as he had in the past and that this trivial matter would not be a big deal.

"Nine deaths, no chance of survival." Yan Changge sighed, "My previous cultivation method was not tolerated by the Heavenly Dao. Later, I worked hard to do good deeds and accumulate merits, but the merits I earned were not even one ten-thousandth of the sins I committed. Even though the spiritual energy of heaven and earth is scarce now, as long as a little bit of it is gathered, this thunder tribulation is enough to take my life."

Qu Lian pushed Yan Changge's hand away, looked at him seriously and said, "I don't quite understand what you said, but there is one thing I understand, that is, if you do bad things, you will be struck by lightning, and doing good things can make up for it, right? I will do good things now, I will donate all my money, I don't want anything, I will exchange it for you!"

"Don't make a fuss," Yan Changge hugged Qu Lian, who was about to take out his phone to make a call and spend money, and said gently, "Even if you spend all the money, it's your merit, not my fault. And my sins... or the negative energy in me, can't be solved by a few good deeds. Maybe a hundred years, a thousand years, or even ten thousand years... After all, human life is at stake, and this is the greatest sin."

"There will always be a way!" Qu Lian grabbed Yan Changge's hand and said, "You have always been powerful, how can you just accept your fate? Didn't you say that science can solve all problems? You just mentioned the thunder tribulation, can't science solve the thunder? Can't you make a lightning rod with a conductor and conduct the lightning into the earth?"

"This is the thunder tribulation I deserve, and I cannot avoid it." Yan Changge said, "And no matter what, I must be struck by lightning, otherwise I will not be able to be reborn."

"Then, what about taking less?" Qu Lian was a little confused at this time, "Electricity is also divided into so many parts, can't we find a way to take less?"

"If I had a magic weapon, I could resist it. This is within the scope of the Heavenly Dao, but...wait, you just said that conductors conduct electricity?" Yan Changge suddenly had an idea. He remembered that he had seen an introduction to superconductors in a high school physics textbook, but because it was not within the scope of the exam, the textbook only mentioned it in one sentence and did not go into detail. Yan Changge had too many things to learn, so he had to focus on the scope of the exam. He had not studied superconductors in detail.

He himself is a conductor and attracts lightning more than ordinary cultivators. However, this world has already developed completely conductive materials with zero resistance. Isn't this something more useful than magic weapons?

He remembered that among the applications of superconductivity, there were superconducting wires and superconducting transformers, which were used for superconducting power transmission to transmit electricity without loss. Of course, there was no such thing as complete losslessness in this world, and superconductors could not completely withstand such a strong lightning strike. But if superconductors were used to conduct part of the lightning into the earth, and he then bore part of the lightning that had been blocked by superconducting transmission, with his skills, he might be able to withstand the remaining lightning, and in this way, the effect of a complete transformation would also be achieved!

"You're right!" Yan Changge's eyes were full of hope. He held Qu Lian's hand and said, "We can't despair. Science can solve all difficulties. We must believe in science and survive from science!"
