Later, Lu Cheng walked around the city's markets and saw many shops with a rich variety of spiritual herbs and demon elixirs.
However, his current level is too high, and it is not easy to find the elixir suitable for Tianwu.
He has completed the practice of "Phoenix Twelve Postures", and next he will practice "Qinglong Seven Postures", mainly practicing the seven cervical vertebrae. For this stage of practice, there are several good elixirs, such as using "Dragon"
"Xucao" combined with Chilong's inner elixir can speed up the training of Tianwu masters.
Lu Cheng kept a Chilong 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 for human trafficking.
"Phoenix Continent" is not a peaceful and peaceful place, nor is it a democratic and legal society 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.
Since there is a demand, there is a supply. So some people robbed 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 the human teeth were mainly girls, and there were relatively few boys. After all, women are weak-minded and easily accept their fate, and if boys remember, they will turn against each other in the future. The Jiu people are not willing to spend money.
Money breeds enemies.
He saw a pair of twin sisters huddled 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 his jade coins and bought the sisters.
He led the sisters out of Renyaxing, and after leaving Xiaojiu City, he held one person in one hand and quickly hurried back to the valley.
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 are you?"
"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 this 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 crawled on the ground: "Thank you, Master."
That's what I say, but five years is too long, and there will be many changes. 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 any mistakes.
Ten-year-old girls are relatively simple-minded. But it’s hard to say what kind of temperament their mother has. 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 from being buried.
Since splitting his soul, his skill has declined, and he can barely maintain the realm of celestial witch. And one-third of the split soul has become an independent individual, and he cannot take it back. If he wants to take back his soul, he still needs to practice.
The method of "integrating the Tao". However, the exercises left by Yin Changsheng do 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 fuse two separate souls at will. Before that, they could only communicate with each other, but could not truly merge.
Together. If either party's body is destroyed, they will be in big 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 your soul and struggle a few more times, your spiritual 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 their supervision.
The days passed, and in a blink of an eye, Lu Chan was 8 months old and could speak.
Lu Chan's voice is clear and loud, and can be heard from a long distance away. As soon as he opens his mouth, Qingmei will be there 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, and 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, completely cracking the hypothesis. 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 this already solved by Chen Jingrun?"
There are expert interpretations behind the news, and major media have reported continuously.
"Goldbach's conjecture originated from letters between the German mathematician Goldbach and the legendary Swiss mathematician Euler in 1742. It 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 that "9
9". In 1924, Germany's Ratmacher proved "7
7". In 1932, 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 who participated in the seminar, such as Wang Yuan, Pan Chengdong and Chen Jingrun, etc.
Achieved very good results.
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 proved it 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.
