The Yan family is a large family in Shangjing. They are not short of money and status, but they are short of masters of cultivation.
Tao Shuguang was born in the Qingcheng faction and was transferred to Beijing to serve.
Although Yan Zhen has no skills, she was beautiful and wise when she was young. She graduated from Peking University majoring in horticulture. The woman chased the man, and soon after meeting Tao Shuguang, they fell in love and got married.
At that time, Yang Feiqiong was not very satisfied and felt that her son should find a cultivator as his wife. However, when she got the news, it was too late, and she was unable to stop it. Fortunately, among the three children born to Yan Zhen, there is also one Qianqian who has good training qualifications and passed the exam of the Ancient Martial Arts Academy at the age of ten, which did not disappoint Yang Feiqiong too much.
Tao Shuguang is Yang Feiqiong's second son, and he has an older brother, Tao Shuming, who lives in Sichuan.
Yang Feiqiong rarely comes to Beijing on weekdays. After retirement, she has been staying in Qingcheng Mountain to cultivate.
She sees Lu Cheng and Jiang Qiuyun every two or three years and gets a lot of benefits from them.
Lu Cheng has an open-minded personality and is easy-going. He is not stingy with giving advice when he meets friends he likes. He is a fellow practitioner of Wuwu. Although he is not in the same system as the Immortal family, many things are in common, so he can give guidance to low-level monks.
In his opinion, there is still hope for Yang Feiqiong to advance to the golden elixir level when his skills reach the late stage of foundation building. Jindan Zhenren is equivalent to a spiritual warrior, Nascent Soul is equivalent to a low-level Heavenly Martial Master, and Buxu Realm is equivalent to a high-level Heavenly Martial Master.
In recent years, Lu Cheng has greatly improved his skills with the help of a variety of elixirs and part of the "Essence of Mountains and Rivers". He is now a sixth-level Heavenly Witch, one level short of the peak of the Heavenly Witch!
He could clearly feel that this last step was difficult to overcome.
Without "Tears of the Stars" or some kind of special and rare high-level elixir, it would take at least a hundred years to advance to the seventh-level Heavenly Witch.
And from the seventh-level Heavenly Witch to the Witch King, there is an even bigger difficulty.
It's like thousands of troops crossing a single-plank bridge. Among a hundred Heavenly Witches, only one or two can become Witch Kings. Most of the others stay in the realm of Heavenly Witches and cannot break through for thousands of years.
Lu Cheng knew in his heart that the sixth-level Heavenly Witch was already a great monk.
It is now 2080, which is still 2970 years away from the 5050 year calculated by scientists that the nine major galaxies will hit the earth. If the movement of celestial bodies stops accelerating, then the remaining 2970 years will be the time for it to develop peacefully and rise peacefully. Once the heaven and earth merge, the Witch King and the Martial King from the outside come in. If his skill is too low, the Five Laws will protect the "Wuru Villa" and "Qingfeng Villa".
The year 2970 seems to be a long time, but for a great monk, it is good to be able to advance to three or five levels.
Lu Cheng's requirement for himself is to improve his skills to the intermediate level of the Witch King before the fusion of heaven and earth.
The Witch King has a total of eight levels, corresponding to eight skull bones, including 1 frontal bone in the front, 1 occipital bone in the back, 2 parietal bones in the upper part, 1 temporal bone on each side, and 1 ethmoid bone in the center of the front of the skull base. and a sphenoid bone in the middle of the skull base. Among them, the two parietal bones are the most difficult to refine. The sign of successful refining is to open up a small world in the parietal bones.
Witch kings like Xi Zhong and He Shu, although they are only fourth and fifth level wizard kings, have already refined a parietal bone and opened up a small world. Therefore, for Lu Cheng, if he wants to become an intermediate level wizard king, he must also open up a small world. In this world, this difficulty is too high. I don’t know how many thousands of years it will take!
Lu Cheng felt a lot of pressure when he thought about the difficulties he would encounter in his future cultivation, so he did not dare to relax at all.
He is the head of the family and wants to hold up a sky for his wife and children.
He felt that his wife Jiang Qiuyun could become a celestial witch and completely get rid of the limitation of life span. She had successfully completed her mission and could relax and enjoy life. However, he himself could not. The road ahead was long and full of thorns. He was far from it. It’s time to stop and rest. As for his children and grandchildren, as long as they are self-reliant and work hard in cultivation, he will be able to accept whatever achievements they will have in the future.
On this day, Lu Cheng called his son Lu Qingshan over and asked, "How far has the research on nuclear fusion reached?"
Lu Qingshan replied: "The problem of large nuclear power plants has been solved, and we are currently doing research on miniaturization."
Lu Cheng said: "If the problem of miniaturization can be solved, I hope to build a spacecraft to visit the nine planets and comets."
"Dad, with your skills, can you fly to the moon without relying on external force?"
"Not yet. Even if I use my magical power, I can only fly five to six thousand kilometers. The distance from the earth to the moon is 380,000 kilometers, and I can't fly up. Even in ancient times, those heavenly wizards and kings of martial arts could not fly up. They all climbed to the sky with the help of Jianmu. Ever since the Great Emperor's 'Jedi Tiantong', there have been very few examples of people ascending during the day."
"What are you going to do on the comet?"
"I heard that large meteors may carry 'tears of the stars'."
"Dad, I think you may be mistaken. Meteors and comets are completely different concepts. Comets are celestial bodies that orbit the sun. Meteors refer to meteoroids running in interstellar space, usually including space materials such as cosmic dust particles and solid blocks. , when approaching the earth, it is attracted by the earth due to the perturbation of the earth's gravity, thereby entering the earth's atmosphere, and causing light trails caused by friction and combustion with the atmosphere.
Comets are mainly composed of water, ammonia, methane, cyanogen, nitrogen, carbon dioxide, etc. The comet nucleus is composed of water condensed into ice, carbon dioxide (dry ice), ammonia and dust particles.
The most abundant elements in meteors are iron, nickel, sulfur, silicon, cobalt, calcium, oxygen, etc. "
"I don't care so much, I just want to go to the major planets and comets."
Lu Qingshan then advised: "Dad, there are a huge number of comets in the universe, but only about 1,600 have been observed. The orbits of comets are different from the orbits of planets. They are extremely flat ellipses, and some are even parabolas or hyperbolas. Orbit. Comets with elliptical orbits can return to the sun regularly and are called periodic comets; comets with parabolic or hyperbolic orbits can only approach the sun once, and once they leave, they will never return. Such comets originally They are not members of the solar system. They are passers-by from outside the solar system. They accidentally broke into the solar system and then returned to the vast depths of the universe without hesitation.
Since a comet is composed of various frozen impurities and dust, when it is far away from the sun, it is just a small cloud-like speck; when it is close to the sun, due to the evaporation, vaporization, expansion, and eruption of the solidified matter, it becomes A comet tail is produced. The tail of a comet is extremely large and can be hundreds of millions of kilometers long.
If you want to find and get close to the comet nucleus, it may not be that easy. "
Lu Cheng said: "When you solve the problem of miniaturization of nuclear fusion, I can invest trillions to build a spaceship. Then I will go around the solar system and see if I can find the 'Tears of the Stars'."
】
Lu Qingshan doesn't quite understand what "Tears of the Stars" means to high-level celestial witches, but he thinks his father's request is quite reasonable. The existing spacecraft technology is already very advanced, and the only thing missing is the power system, which is still chemical fuel. , wrapping kerosene, alcohol, unbiased dimethylhydrazine, liquid hydrogen, etc. as combustion agents, and using oxidants provided by liquid oxygen, dinitrogen tetroxide, etc. to assist combustion. This power system is flawed. Once the miniaturization of nuclear fusion is solved, the spacecraft will achieve a huge leap.
