“Ah, what’s the difference? Aren’t they all the same?”

Chen Mobai’s knowledge of formations was limited to what he learned in class. As for the Azure Water Formation, he just thought it was slightly more advanced than the ones explained in the usual classes, but there was no fundamental difference.

How could they be two different systems?

“On Earth, all the resources for cultivation have been nationalized. All the spiritual veins of the thirty-six heavenly caves and seventy-two blessed lands have been unified by the Deification ancestor using supreme treasures.”

“Therefore, on Earth, people generally don’t study formations that require the insertion of formation flags into spiritual veins. However, this knowledge is the foundation of formations, so we, as formation teachers, will explain it in high school classes.”

“But in reality, formations that require the extraction of spiritual vein power and are above the second order have become dust in history. The direction of formation development supported and guided by the Immortal Gate and various Taoist academies is to borrow the power of natural phenomena and the sun, moon, and stars.”

After Chan Si finished speaking, Chen Mobai finally understood. It turned out that the Azure Water Formation, which needed to be rooted in water veins, was extremely rare in the entire Immortal Gate.

It wasn’t that the formation was difficult, but it was hard to get permission from the Immortal Gate’s Department of Natural Resources to extract the power of the spiritual veins within the Immortal Gate’s territory for formation.

“Perhaps the private tutor my mother hired was a cultivator who had participated in the opening of the sea area, so he was quite persistent in formations that required water veins.”

Chen Mobai tried to explain, Chan Si looked at him suspiciously, but did not delve into it.

“Give me your phone number.”

“Huh?”

Chen Mobai didn’t expect Chan Si to suddenly ask for his number, and he was a little taken aback.

“I only have a slight understanding of formations. In recent years, teaching at your school has made up for my foundation in this area. This Azure Water Formation is a bit beyond my ability, and I need to go back and ask for advice. There is a senior professor in the field of formations at Danzhu Academy for exchange, I will go back and consult him. Give me your phone number, we can add each other as friends, and I will forward you the answer as soon as I have it.”

Chen Mobai didn’t expect Chan Si to be so modest. He was clearly a teacher who taught formations, but he said he only had a slight understanding.

“Thank you, Teacher Chan.”

After saying that, Chen Mobai immediately took out his phone and added Chan Si as a friend.

Just as he was about to leave, he felt a bit embarrassed. He scanned the thirty pages of detailed explanations of the Azure Water Formation stored on his phone into a text document and sent it to Chan Si, saying it was reference material given to him by the private tutor.

“Okay, with these, I should be able to give you an answer in a couple of days. After all, the way of formations, myriad changes all come from the same origin.”

Chan Si’s eyes lit up when she saw the document Chen Mobai sent over. She took out her own paper and pen and began to calculate and simulate the operation of the Azure Water Formation, seemingly intending to first use her own ability to see if she could deduce all the mysteries of the formation.

Seeing her immersed in her work, Chen Mobai didn’t dare to disturb her. He left and closed the door for her.

He originally wanted to give Chan Si the original copy of “Detailed Explanation of the Azure Water Formation” for reference, but considering that the origin of this thing might be outside the territory of the Immortal Gate, and it was evidence that he might be a murderer, he decided to be cautious.

So after thinking it over, he decided to go back and scan the content of the entire book into a document, one word at a time, eliminating all possible traces of exposure, and then send it to Chan Si.

After leaving the office, Chen Mobai planned to go straight home.

He now had a second-order mid-grade spiritual vein treasure land, and he looked down on the school’s first-order spiritual energy cultivation room.

But after thinking about it, it’s better not to attract attention.

The Fifth High School of the Immortal Gate is a national school. The students who study here are basically from ordinary families. Even geniuses like Song Zheng and Yan Bingxuan, who are in the late stage of Qi Refining, cherish the two hours of free time every afternoon.

There are three students who have reached the eighth level of Qi Refining and have given up the school’s cultivation room time. The top-tier first-order spiritual energy is somewhat insufficient for them. Their parents have helped them rent a second-order lower-grade single cultivation room outside, and they leave school directly after morning classes.

So, if Chen Mobai doesn’t use the school’s cultivation room, it will definitely attract attention if people find out.

Qi Refining cultivators can’t cultivate for more than eight hours a day, otherwise their meridians and dantian won’t be able to bear it. Chen Mobai doesn’t plan to waste time here.

So in the school’s cultivation room, he took out the handbook of the Flying Probe Sect disciple dropped by the brown-robed youth to read.

It was only twelve pages thin.

It spent a lot of space introducing the history of the Flying Probe Sect. The founder was a disciple of the Flying Sand Sect in the Ten Directions Hall. After successfully establishing his foundation, he left the sect because he had no hope of forming his golden core.

The last two or three pages were all about how the founder of the Flying Probe Sect came to the Eastern Wilderness and established a foundation that lasted for three hundred years, and his story of dominating the eight directions.

Then, there were the rules that all major sects have, such as not deceiving the master and destroying the ancestor, not doing evil, etc.

These were of no use to Chen Mobai. Only the page about the sect’s benefits let him roughly know the origin of the spirit stones.

Joining the Flying Probe Sect, apart from the responsibilities of the sect, naturally also comes with the annual distribution of spirit stones.

Disciples in the early stage of Qi Refining can receive five spirit stones a year; those in the middle stage of Qi Refining can receive ten spirit stones; and those in the late stage of Qi Refining can receive twenty.

This brown-robed youth was at the sixth level of Qi Refining, already at the peak of the middle stage. Ten spirit stones were hardly enough for his cultivation. He must have been trying to earn extra income, conspiring with the old man to open this underwater mansion, hoping to make a fortune.

However, he didn’t expect that he would be killed by the old man in the underwater mansion before he had a chance to show off his skills.

The last page was the signature of the brown-robed youth and the stamp of the Flying Probe Sect.

This sect manual was printed in the year 6478 of the Yuan Era.

The Yuan Era?

It must be the local calendar of the Eastern Wilderness!

At this point, Chen Mobai had a vague idea about the location of the underwater mansion.

This place called the Eastern Wilderness should have plenty of spirit stones.

If he could achieve a high level of cultivation in the future, he would definitely leave the underwater mansion and explore the land.

After reading the disciple’s manual of the Flying Probe Sect, Chen Mobai took out the needle box, gently opened it, and tried to refine it.

There were twelve earthy yellow flying needles neatly arranged inside. He infused his spiritual power into them, and one by one, the flying needles rose. In the end, with all his effort, a total of ten flying needles combined with his spiritual power and slowly ascended.

It seemed that at the sixth level of Qi Refining, one could control all the flying needles?

Chen Mobai thought so. He was at the fifth level of Qi Refining and could control ten needles. If he fully refined them, it would be just right to use.

However, he had never controlled a magical instrument before. After only three minutes, he found that most of his spiritual power had been consumed, and the ten flying needles fell uncontrollably.

“No wonder he always launched them three at a time.”

Chen Mobai recalled the scene of the brown-robed youth casting spells, realizing how wrong he was. Even if one could lift twelve flying needles at the sixth level of Qi Refining, to control them smoothly, one would probably need to be at least at the seventh level of Qi Refining.

After he meditated to recover his spiritual power, he tried again to control three flying needles. Although he managed to keep them in the air for a quarter of an hour, the earthy yellow long needles were incredibly stiff and unresponsive.

Wouldn’t it be nice if there were a matching refining mantra?
