Yan Aohan glanced at Yi Yunfei and said, "I plan to have you set up a formation here starting tomorrow."
"What kind of formation?" Yi Yunfei asked.
Yan Aohan explained, "There are few people left here. Some are under Yan Zuo’s training. I will have Yan Zuo take the rest out to adapt to life outside. Once Qingyun returns from the Saint Academy, you can contact him. Those people will be entirely at your disposal.
The ones staying here will patrol and guard the Tianshui River."
Yan Aohan picked up a piece of roasted rabbit meat, took a bite, and continued, "You know the situation with the Tianshui River. Countless divine souls are nurtured beneath it.
We are not forbidding these souls from waking up. It is just not the right time for them to awaken. Most importantly, we do not want them wandering around randomly after waking, which would disrupt the natural order.
Therefore, I want the remaining people to patrol the Tianshui River. However, this place must remain hidden. Although there is currently a barrier, you know it is getting thinner. Eventually, the barrier will collapse. If we are not here when it collapses, this place will be exposed to the world. This could attract people with bad intentions, disturbing the divine souls here. I cannot predict the final result of that."
Yan Aohan took a sip of wine. "So, I want you to work together to set up a large concealment formation. Even if the barrier collapses, no one will be able to discover anything here."
After stating his purpose, Yan Aohan continued drinking from his cup.
Ouyang Tianyun nodded slightly after listening. "Hearing you say that, this is indeed a major project."
Setting up a small formation does not take much time, but a large formation requires considerable effort.
"I have thought it through. Ani is most familiar with this aspect. She will lead, and the four of you will cooperate with her." Yan Aohan had planned everything carefully.
Regarding formations, Zhu Yanyi’s experience was indeed the richest. The other four had no objections to this.
Zhu Yanyi took a sip of mushroom soup and said, "I will draw a complete map of the formation, then divide it into five parts. The four senior brothers will set up the east, south, west, and north sections according to my instructions. I will handle the center. Once everyone completes their section, I will adjust and connect them. This method is effective and fast."
"As long as it does not affect the formation, we have no problem," Yi Yunfei said.
"It will not have any negative impact. You just need to bury the corresponding items in the marked locations. Do not get the positions wrong, do not get the order wrong, and do not get the items wrong. Then there will be no issues," Zhu Yanyi said with a smile.
As long as the separate formations are not activated, there will be no problems. Even if there are mistakes in the middle, Zhu Yanyi will check everything when connecting them at the end. Basically, this formation will not have major issues.
Hearing Zhu Yanyi’s words, everyone agreed. This straightforward method was relatively the best, so they were not in a hurry and planned to follow Zhu Yanyi’s approach.
After finishing the celebration meal, Zhu Yanyi returned to her room and entered the Ruyi Space.
Drawing a formation map is not a simple task. Zhu Yanyi had to calculate the ratios based on the entire barrier’s range. Formations cannot be handled carelessly; even a slight distance error could create a trap. Therefore, Zhu Yanyi needed absolute clarity.
So, Zhu Yanyi drew slowly in the space. She stayed in the space for a full month, which was only one day and night outside. When she came out, the blueprint was complete.
Zhu Yanyi handed the blueprint to Yan Aohan for him to review first.
Yan Aohan took it and looked closely.
Zhu Yanyi’s blueprint was very clear. It clearly marked how many meters apart items should be, the quantity, height, and distance. It specified where to plant a tree, where to plant a flower, and where to bury a stone. Every aspect was very clear.
"These are the required materials." Zhu Yanyi handed the material list to Yan Aohan. Such tasks needed Yan Aohan to assign people to complete.
Yan Aohan looked at the material list. Although preparing some items on the list would take time, there were no major difficulties. He said, "I will have people deliver these items within a week at most."
Zhu Yanyi nodded. "I will discuss the formation with the senior brothers these days. This way, when you deliver the items in a week, everyone will not be flustered."
Zhu Yanyi gave Yan Aohan a complete blueprint. She also needed to divide this blueprint, so she specifically drew another copy and divided it into five directions: east, south, west, north, and center.
Then Yan Aohan sent people to find the materials, while Zhu Yanyi began discussing the formation with Sikong Xuran and the other four.
As doctors like them, they needed to learn medicinal formations.
To learn medicinal formations, one must first learn formations. So, even Yu Qingyun, who only understood a little about medicinal formations, knew the mysteries of formations. Therefore, she took advantage of these few days to learn from Zhu Yanyi, essentially cramming knowledge about formations.
Zhu Yanyi explained everything they did not understand very seriously and carefully. After all, they would need to complete parts independently later. So, while there was still time, she made sure they understood the specific details of this formation, especially the fine points, which could not be handled carelessly.
"You must also look clearly at what items are needed for each location. I have prepared the relevant sizes for the tree seedlings needed, including what kind of seedlings to use, the planting distance, and how many stones to bury underground. I have written everything clearly. You must not make mistakes, and you must not mess up the order.
Later, you cannot plant locust trees where banyan trees should be planted, or pine trees where locust trees should be planted. If that happens, the formation will not only fail to work, but it might also cost us our lives."
Zhu Yanyi was very clear and strict about the details.
"Since they are trees, do we need to be so specific about which tree to plant?" Yu Qingyun asked. He was the weakest among the four men in terms of formations, which is why he asked.
"Of course there is a difference. Each type of tree has its own characteristics.
For example, the function of a banyan tree is fusion. Its role in the formation is to use the formation’s operation to lock and fuse all the spiritual energy within this barrier. Even if the barrier collapses later, the spiritual energy will not disappear due to the collapse."
