On this day, Lu Chen's mood was a little depressed, and he wanted to impact the foundation building period, but no one taught him that he had read the method of how to build a foundation issued by the sect several times, and he had no clue, so with the idea of trying his luck, he found Luo Ling'er.

"Senior sister, do you know how to hit the foundation building period?"

"You know, isn't it easy to build a foundation?" Luo Linger obviously knew how to build a foundation.

"Please teach me!" Lu Chen solemnly bowed, this is a kindness to teach karma and solve doubts.

"Okay! Aunt Xue just taught me when I built the foundation the year before last!"

"The year before last, you built the foundation, junior sister, you have already built the foundation?" Lu Chen was stunned, Luo Ling'er was only fifteen years old this year, and building the foundation the year before last, which means that the foundation was successfully built at the age of thirteen, the geniuses in the Dongzhou region of the mortal realm recorded in the Qingxia Sect's classic "Dongzhou Chronicles" were the earliest to build the foundation at the age of fifteen, and it was obvious that Luo Linger's true cultivation aura was hidden by the magic weapon on her body.

"What's all the fuss about, the children of those families I know have built a foundation for about the same time as me!"

"Don't talk about this, senior brother, listen carefully, I'll tell you everything I've heard about foundation building. Afraid that Lu Chen would continue to ask about his identity, Luo Linger quickly diverted the topic.

Lu Chen knew that everyone had their own secrets, and since Luo Linger didn't want to mention his identity, Lu Chen naturally wouldn't continue the topic.

"To put it simply, qi refining is the process of self-cultivation, the qi refining period monks will absorb the external spiritual energy into the dantian, and then run the spiritual energy throughout the body, although it can also strengthen the body, but it will make people live a long life and not invade all diseases, like the life span of the monks in the mortal realm qi refining period is mostly about 100 years old.

However, building the foundation is a process of washing the marrow of the I Ching, which not only excretes the meridians, but also the impurities of the bones, tendons, and medullary organs from the body, and eventually turns the spiritual energy of the dantian and the whole body into a liquid state, covering the whole body, so as to lay the foundation for the subsequent cultivation, so it is called building the foundation.

Only when the foundation is successfully built can it be regarded as truly stepping into the door of cultivating immortals.

From refining qi to building a foundation, it can be said that it is extremely difficult for monks below the qualification of the heavenly spirit root, because what is needed to build a foundation is to press the gaseous spiritual power of the whole body into a little bit of liquid spiritual power, and finally cover the whole body, and even penetrate deep into the bone marrow.

Therefore, for most Qi refining stage disciples, if they want to succeed in building a foundation, they must take Zhuji Dan, and sometimes they need more than one Zhuji Dan, which is the reason for their qualifications.

This is the reason why many disciples of the Great Perfection of the Qi Refining Period in the inner sect of the Qingxia Sect have served the Foundation Building Pill twice, but they still have not succeeded in building the foundation.

Moreover, in Dongzhou, refining Zhuji Dan is not an easy task.

First, the level of alchemists is average, so the rate of becoming a pill is very low, and if dozens of herbs are thrown into a furnace, only a dozen pills will be obtained, and sometimes even a furnace of waste pills will be refined.

Second, among the materials for refining Zhuji Dan, there is the main medicine Ning Xian Cao, which not only requires a hundred years of age, but also this medicinal herb currently only grows in Jiuzhi Mountain in Dongzhou, and cannot be transplanted to survive.

However, at present, the mountain range here has been jointly controlled by the Guiyuan Sect and the Royal Beast Sect, which are the strongest in Dongzhou, and sects such as Zimen Valley, Xuanyin Pavilion, Wuji Gate, Tianxuan Sect, Qingxia Sect and other sects need to pay a great price to exchange for this grass.

If the outer disciples of the Qingxia Sect want to get the Zhuji Dan, first, those who have made outstanding contributions to the sect can be rewarded with one, and the second is to be among the best in the outer gate competition, like this outer door competition, the sect gave an exception to the thirty-nine disciples who entered the inner gate to issue the lower grade Zhuji Dan, which was exchanged by the sect for the price of 390,000 lower grade spirit stones and the Guiyuan Sect. Thirdly, you can go to Qingyuanfang City to try your luck, but the probability of encountering it is very small, because as soon as Tsukidan appears, he will be robbed in an instant. ”

"Thank you for your advice!" Lu Chen bowed to Luo Ling'er.

"Senior Brother Lu, don't be so polite, we are neighbors, I wish Senior Brother an early foundation!" Luo Linger returned the salute.
