Later, Lu Cheng walked around the city's markets and saw many shops with a rich variety of spiritual herbs and demon pills.
However, his current level is too high, and it is not easy to find the elixir suitable for Tianwu to take.
He has completed the practice of "Phoenix Twelve Postures" and will next practice "Qinglong Seven Postures", mainly practicing the seven cervical vertebrae. For this stage of training, there are several good elixirs. For example, using "Dragon Beard Grass" together with Chilong's inner elixir can speed up the training of Tianwu masters.
Lu Cheng kept a piece of Chilong's inner elixir in his hand, but he never put it to use.
He bought two more Chilong Neidan and several bundles of asparagus grass in the city.
Then, he found "Ren Ya Xing", a place where people are trafficked.
"Phoenix Continent" is not a peaceful and peaceful place, nor is it a society governed by democracy and rule of law in later generations. Instead, it is a semi-slave and semi-feudal society, and human trafficking is normal.
The Xiaojiu clan belongs to a clan second only to the Feng clan. In order to maintain the clan's leading position, it needs to purchase some girls from time to time to continue the bloodline of the Xiaojiu clan.
If there is demand, there will be supply. So some people robbed the girls outside, snatched away the girls from scattered small clan families, and sent them to the Renya Shop in Xiaojiu City for sale.
Lu Cheng took a look around and found that the children in Ren Ya Xing were mainly girls, with relatively few boys. After all, women are weak-minded and easily accept their fate, while boys, if they remember, will turn against each other in the future. The Dove Clan is also unwilling to spend money to cultivate enemies.
He saw a pair of twin sisters curled up among the hundred or so girls. Although they were unkempt, they had regular features and relatively long Qi on their heads, so he took out the jade coins and bought the sisters.
He led the sisters out of Ren Ya Xing, and after leaving Xiaojiu City, he quickly hurried back to the valley with one person in each hand.
Qingmei met the sisters, took them to a nearby small lake to bathe, changed their clothes, and then brought them back.

Lu Cheng asked: "What are your names?"
One of the girls said: "My name is Ji Si, and I am the elder sister; her name is Ji Wu, and she is the younger sister."
"How old?"
"Ten years old."
A ten-year-old is a little girl in the later world, but she is no longer young in another world, and she gets married at the age of twelve or thirteen.
Lu Cheng said: "Ji is a common surname, how could you fall into the hands of Ren Yazi?"
Sister Ji Wu said: "My father is a branch of a large family. He took dozens of people to open up wasteland in distant places and lived in the mountains. I didn't expect to encounter robbers."
"Are your parents still alive?"
"My father is dead. My mother was sold in Xiaojiu City."
"Are your parents both monks?"
"My father is a junior spiritual warrior, and my mother is at the fifth level of innateness."
"In that case, you follow Qingmei and listen to her instructions. If she is satisfied, I will consider redeeming your mother after five years."
The two sisters prostrated on the ground: "Thank you, Master."
That's what I say, but five years is too long, and many changes will occur. It's hard to say whether it can be redeemed.
Lu Cheng doesn't want to be the savior, he needs buffer time.
Five years later, although "Lu Chan" is only five years old, she can use her 500-mile-long spiritual consciousness to turn into a sword and have a certain ability to protect herself.
Before the age of five, there is no room for mistakes.
The ten-year-old girl is relatively simple-minded. But it's hard to say what their mother's character is like. What if Qingmei is not paying attention and hurts Lu Chan?
Lu Cheng has high hopes for the clone "Lu Chan", which is the key to his attempt to escape being buried as a sacrifice.
Since splitting his soul, his skill has declined and he can barely maintain the realm of the Heavenly Witch. The one-third of the separated consciousness has become an independent individual, and he cannot take it back. If you want to take back your soul, you must practice the "harmony" method. However, the skills left by Yin Changsheng did not include this part.
According to Lu Cheng's understanding, it is possible that one has to cultivate to the level of the Witch King to have the ability to "integrate the Tao" and merge two separate souls at will. Before this, they could only communicate with each other, but could not truly integrate together. If either party's body is destroyed, they will be in great trouble.
For example, if the spiritual body Lu Chan's physical body is destroyed, he needs to find a new physical body. The physical body cannot be found casually. If the physical body found in a hurry is not suitable for use, he must continue to search for it. Every time he takes the body, he will If you lose a little bit of soul and struggle a few more times, your consciousness will be seriously damaged and you will be shaken by the wind and rain and disappear between heaven and earth.
Therefore, Lu Cheng strictly ordered Qingmei to take good care of her and never let Lu Chan get hurt.
He also asked Ying Chu, Yao Shi and Si Ping to strengthen supervision.
The days passed, and in a blink of an eye, Lu Chan was 8 months old and could speak.
Lu Chan's voice was clear and loud, and could be heard from a long distance away. As soon as he opens his mouth, green plum blossoms will appear in an instant.
So Lu Cheng felt relieved a little, and took advantage of the night to return to modern times with his mind wandering.
The spring of 2058 was particularly bright. Because of the revival of spiritual energy, there were birds singing and flowers fragrant everywhere.
On March 20, CCTV broadcast a news: "After cracking the Riemann Hypothesis half a year ago, my country's young mathematicians Lu Qingyan and Ling Shiqi recently collaborated to publish a 300-page monograph, which completely cracked the Solved Goldbach's conjecture, one of the world's three major mathematical problems."
After the news was broadcast, many people felt strange: "What is Goldbach's conjecture? Wasn't it already solved by Chen Jingrun?"
There are expert interpretations behind the news, and major media have reported continuously.
"Goldbach's conjecture originated from a 1742 letter between the German mathematician Goldbach and the legendary Swiss mathematician Euler, and is considered one of the greatest conjectures in the history of mathematics. To this day, mathematicians still cannot prove all numbers It's all conjecture. It's one of the oldest open questions in all of mathematics.
In 1920, Brown of Norway proved "9 + 9". In 1924, Germany's Ratmacher proved "7 + 7". In 1932, the British Esterman proved "6 + 6"...
In 1950, Hua Luogeng returned from the United States and organized a number theory research seminar at the Institute of Mathematics, Chinese Academy of Sciences, choosing Goldbach's conjecture as the topic of discussion. Students participating in the seminar, such as Wang Yuan, Pan Chengdong, and Chen Jingrun, have achieved very good results in proving Goldbach's conjecture.
In 1956, Wang Yuan proved "3+4"; in the same year, the former Soviet mathematician A. Vinogradov proved "3+3"; in 1957, Wang Yuan proved "2+3"; Pan Chengdong in In 1962, "1+5" was proved; in 1966, Chen Jingrun proved "1+2".
Lu Qingyan and Ling Shiqiu stood on the basis of their predecessors and completely proved the entire Goldbach conjecture. This is a step forward for natural science and a step forward for mankind to trudge hard, unswervingly, and continue towards glory..."
In the next half month, news continued to come from abroad. The proofs of Lu Qingyan and Ling Shiqi were recognized by many top mathematicians around the world.
After more than a month of fermentation, on May 7, at the Great Hall of Beijing, Lu Qingyan, Ling Shiqiu, and two other scientific researchers received this year’s Medal of the Republic.
The Medal of the Republic is the country's highest honor, and every recipient is a remarkable figure, such as Yu Min, Shen Jilan, Sun Jiadong, Li Yannian, Zhang Fuqing, Yuan Longping, Huang Xuhua, Tu Youyou, Zhong Nanshan, etc.
