"Uncle, open the door quickly, I'm Cao Ying."

Early in the morning, Cao Ying appeared in Yunzhong City and knocked on Lin Jiang's door. Lin Jiang looked outside with his spiritual sense and found that it was indeed Cao Ying, but there was someone beside her, so he quickly put away the sand sculptures.

"Cao Ying, why are you back?"

"Senior Qin, you are here too."

Lin Jiang opened the door and saw Qin Yan beside Cao Ying, and hurriedly saluted.

"My little sister is clamoring to go home to see her, and my master is worried, so I came to look after her."

"Senior Ouyang is thoughtful, please come in."

Lin Jiang hurriedly greeted the two people to come in. Cao Ying really needs someone to protect her, otherwise, with her talent and understanding, she doesn't know how much jealousy she will suffer, and maybe someone will do something dirty.

Qin Yan walked into Lin Jiang's house and frowned slightly. It was such a small and shabby house. She was a little uncomfortable. She had an independent cave in Zhongxing Sect. With her Jindan cultivation, her cave could be built to a size of ten acres. Lin Jiang's place was at most seventy square meters, and it couldn't be bigger.

"I'm sorry to have embarrassed you, Fellow Daoist Qin."

"You can move to the north of the city in the future."

"I'll definitely go there if I have the chance."

Lin Jiang nodded. The north of Yunzhong City is the rich area in the city. The buildings there are much more sparse than in the other three places, and the per capita residential area is very large. Naturally, the price is much more expensive.

However, Lin Jiang will definitely go there, because if he wants to break through the foundation-building period, he needs an environment with sufficient spiritual energy. The spirit gathering array can solve this problem, but the spirit gathering array needs to continuously install spirit stones. Lin Jiang is alone and cannot replace spirit stones during his retreat. He can only rent a cave with sufficient spiritual energy. The cave in the north of the city is his goal.

"Uncle, I miss your meal."

"Okay, I'll make it for you right away. Wait a minute and entertain your senior sister."

Lin Jiang said with a smile. He still dotes on Cao Ying. After all, he is over a hundred years old and likes to see children.

Lin Jiang tied an apron, went into the kitchen, cooked a few dishes, and brought them out for Cao Ying to enjoy. Cao Ying smiled and ate.

"You have good skills. You can work in the dining hall of Zhonghang Sect."

"Sister, can you get my uncle to work in the dining hall?"

"No, he is not a disciple of our sect."

"Ah, can you ask Master for mercy?"

"Master can't do it either. The dining hall is an important place of the sect. Not everyone can come in."

Tan Yan shook her head. Many disciples of Zhonghang Sect still need to eat. If a bad guy enters the dining hall, it will be terrible. They can kill all their low-level disciples. Therefore, the dining hall of Zhonghang Sect must be staffed by people with clean backgrounds, which means that they have been members of Zhonghang Sect for generations.

"Cao Ying, I don't want to go to Zhonghang Sect either. I am used to being a casual cultivator and free. Don't bother me, senior."

"Okay, uncle, I came back this time to give you something good."

"What good thing?"

"Foundation Building Pills, look..."

Cao Ying took out a jade bottle and poured out the Foundation Building Pills from it.

"Five?"

Lin Jiang was shocked when he saw the Foundation Building Pills. Five Foundation Building Pills at once?

"Yes, five. My master's grandfather Chen Mingyang is the head of the sect's Alchemy Hall and he has five disciples. I asked each of them for a Foundation Establishment Pill. Unfortunately, two of my master's disciples are not good enough to refine Foundation Establishment Pills, otherwise I could have asked for two more."

"Xiaoying, this..."

Lin Jiang was a little confused. Is Cao Ying so powerful? Aren't these Foundation Establishment Pills very expensive?

Tan Yan, who was listening, shook her head and said, "Fellow Daoist Lin, please keep it. This is a piece of filial piety from the little junior sister."

"This is too expensive."

"It's not expensive. You casual cultivators need 20,000 or 30,000 spirit stones to buy a foundation-building pill, but it's not for us. The total cost of a furnace of foundation-building pills is only 20,000 spirit stones, but our senior brothers have very good alchemy skills and can make at least eight pills."

Tan Yan said that the retail price is different from the cost price. The retail price includes various expenses. Their alchemists only spend 2,000 or 3,000 spirit stones to make a foundation-building pill. Chen Mingyang's disciples are at least in the late stage of foundation-building. What are 2,000 or 3,000 spirit stones for them?

"This, Lin is unworthy of it."

Lin Jiang waved his hand, but his eyes could not leave the foundation-building pill. After participating in these auctions, the final cost of each foundation-building pill was about 40,000 spirit stones. Five pills would cost nearly 200,000 spirit stones, which is a huge sum of money for casual cultivators.

Lin Jiang can guarantee that more than 95% of the Qi training cultivators in Yunzhong City cannot earn 200,000 spirit stones in 20 years, and most of them are in extreme poverty. Just

look at the housing conditions around you and you will know that it is common for three to five people to live in a house of 50 to 60 square meters, and in extreme cases, there are seven to eight people. If you don't know, you might think you have come to a black factory. Is this still cultivation?

"You raised the little junior sister, this is the little junior sister's filial piety to you, how can you say that you are unworthy of it, fellow Daoist Lin, please keep it, don't waste the little junior sister's

filial piety." Qin Yan knew what Lin Jiang meant, she was just being polite, and immediately gave Lin Jiang a way out.

"Yes, uncle, you should keep it quickly, you have to succeed in building your foundation, I also hope to eat the food cooked by your uncle in a hundred years"

"Okay, I just need the foundation building pill, then I'll keep it"

Lin Jiang said reservedly, hypocritical to the point that he was embarrassed, he obviously wanted it so much.

"I haven't been to Yunzhong City for many years, I'm going to go for a walk, you stay at home and don't let Xiaoying go out, understand?"

"I know, don't worry"

Lin Jiang nodded, very seriously, Ouyang Qing asked Qin Yan to come to report to protect Cao Ying, there is no reason, Lin Jiang is not that stupid.

After Qin Yan left, Cao Ying could say some personal words to Lin Jiang. Lin Jiang also reminded Cao Ying that in Zhonghang Sect, it was different from home. She should be careful about what she said and did. She could be sweet-mouthed but not mean. She could do more things and it was okay to suffer a small loss, but when it came to the bottom line and core interests, she had to not give in.

······

Cao Ying did not stay at home overnight and left on the same day. Disciples like her who had just joined the sect for a few years were generally not allowed to leave the sect for their safety. This time, Ouyang Qing gave her special approval.

After Cao Ying left, Lin Jiang was excited for a long time when he looked at the five foundation-building pills. He had lived for more than a hundred years, and raising Cao Ying was his highest-return investment. He made a lot of money from this foundation-building pill

alone. He went to Yingchun Tower to reward himself in the evening. Ten days later, Lin Jiang went to the auction of Juxing Tower again. He still had to pretend. He couldn't be too extravagant after having the foundation-building pills.

It was just that for the foundation-building pills at the auction, as long as they were over 30,000 spirit stones, he would not bid anymore, and he was just a runner-up.

After the auction, Lin Jiang came to the north of the city. After entering the north of the city, his senses were immediately different. The buildings here were no longer crowded, short and dilapidated, but luxurious courtyards one after another, with three, five, and eight entrances.

The pedestrians on the road, the level of cultivation also immediately improved. There were very few people in the early and middle stages of Qi training, and the foundation-building stage was everywhere, and occasionally even the golden elixir stage could be seen.

The north of the city not only had luxurious buildings, but also had mountains. There were mountains in other places before, but they had long been razed to the ground and turned into dense buildings. Is it to maximize resources? Moving mountains and seas is not a difficult task for cultivators.

The mountains in the north of the city are the birthplace of the spiritual veins of Yunzhong City, and they cannot be destroyed, but Yunzhong City has opened up caves on the mountains for rent.

Lin Jiang asked around and found out that the caves in the north of the city were divided into four levels: heaven, earth, black and yellow. The heaven-level caves could even be used by Yuanying stage ancestors for daily practice. The Yuanying ancestors of Zhongxing Sect and Yunjian Sect who guarded Yunzhong City lived in the heaven-level caves.

The earth-level caves were enough for Jindan stage to live in. Most of the high-level people in Yunzhong City also lived in this area. The black and yellow levels were enough for daily practice in the foundation building stage. The concentration of spiritual energy in the black and yellow levels was similar, but the area was different, the decoration inside was different, and the price was also different.

The rent of the caves in the north of the city was high. A yellow-level cave with an area of ​​less than 20 square meters cost 5,000 spirit stones a year. This price could rent a house of nearly 100 square meters in the most crowded South City, and a house of 150 square meters in the West City.

But even so, the caves in the north of the city were in short supply. There were no empty caves in the yellow and black levels, which made Lin Jiang sigh that the gap between the rich and the poor in this world was so huge. Ordinary casual cultivators were still struggling on the poverty line, while the casual cultivators here were already so rich.

Lin Jiang left a deposit and booked a cave residence that he would return after eight months. After living in it for eight months, Lin Jiang was ready to start his breakthrough.

After returning home, Lin Jiang began to collect some information on breaking through the foundation building stage. Before, his cultivation was still far from the foundation building stage, and Lin Jiang did not pay attention to it. It is not too late to prepare now.

The most important thing for the Qi training stage to break through the foundation building stage is to compress the spiritual energy absorbed into the Dantian in the body from gas to liquid. This process requires the use of foundation building pills to provide strong spiritual pressure, which may damage the meridians, so the auxiliary pills for foundation building include some pills for reporting and protecting the meridians.

If conditions permit, you can also find an elder to protect you. Once the meridians are disordered, there is a danger of going crazy, but Lin Jiang cannot find a reliable foundation building stage to protect him, so he can only prepare more pills.

The foundation building pills sent by Cao Ying helped Lin Jiang a lot, saving him a lot of spiritual stones and making adequate preparations. Otherwise, Lin Jiang really had to find a way to raise some more money.

Eight months later, Lin Jiang celebrated his 163rd birthday and successfully moved into the yellow-level cave in the north of the city, preparing to build his foundation.
