The new plan is as follows:

[2:40-4:30 paused; time has been automatically allocated to .]

[2:40-5:30 is the time for .]

Chen Yi's expression brightened with joy.

That's great! As long as I skip breakfast, I can have almost three and a half hours to study formations...

With more than three hours of practice every day, plus the effect of "calm mind", your formation skills will definitely improve by leaps and bounds!

"Not enough! System, let me see your limits!" Chen Yi shouted.

Please speak your mind!

Chen Yi's eyes flashed with madness as he said, "Give the body-tempering time and spell study time to the formation as well!"

Since his two body-refining methods are already highly accomplished and difficult to improve to perfection in a short time, he might as well use the time to quickly complete the formation.

The same applies to magic. Although he has just acquired a new magic, this new magic requires both refining the sword pellet and mastering the knowledge of formations. The former can be completed in the dream space, which is more efficient, while the latter is exactly what he wants.

[Under investigation...]

[Approved.]

[Today's 15:00-17:00 time slot and 17:30-19:00 time slot will be automatically assigned to the plan.]

"I refuse to believe that I can't handle the array patterns on your tiny sword pellet like this?"

Chen Yi chuckled wickedly, then decisively pulled out his phone and began studying.

Although it was in the dark campus, with only faint moonlight shining down.

But his eyes shone like a blazing sun.

The unfamiliar knowledge in the book flowed smoothly into my brain, but it didn't slip away. Instead, it was transformed into my own knowledge and solidified over time.

An hour later, he finished reading the book on formations.

Fortunately, he had the foresight to borrow some books on formations from the library a few days ago while preparing for the monthly exam.

In addition, he also asked Wu Lingyao for the remaining array books.

She was completely bewildered. Wasn't it just a matter of learning about it?

One book wasn't enough for you, so you asked for several more. How can you possibly read them all?

Chen Yi simply made up an excuse to brush it off, and Wu Lingyao didn't press him further. She just told him to remember to prepare for the secret realm and not to spend too much time on other things.

"How can becoming stronger be considered something else?"

He was engrossed in reading the borrowed book on array formations...

[Through your efforts, your formation skills have improved; proficiency +6]

[Through effort...]

The increase in proficiency meant that Chen Yi was constantly accumulating knowledge about formations.

He was like a dried-up sea, freely absorbing nourishment from the ocean of array knowledge!

Those array patterns that once left him bewildered have now become fascinating and mysterious designs.

"Qian, Kun, Zhen, Xun, Kan, Li, Gen, Dui, Jia, Yi, Bing, Ding, Zi, Chou, Yin, Mao..."

At this moment, Chen Yi felt as if he were reciting the periodic table of elements.

"The way of formations is truly profound. Astronomy, geography, stars, earth veins, spiritual energy, blood and evil spirits can all become part of a formation."

During the day today, besides attending regular classes, he also went to see Liu Qing during the break.

Generally speaking, with a schedule in place, Chen Yi wouldn't waste even a five-minute break between classes; instead, he would use it for cultivation.

But he had important business to discuss with Liu Qing, which also aligned with the grand plan of "building a foundation in a hundred days".

Because he was going to the secret realm, according to the requirements of Xiande Middle School, he had to obtain the school's consent and sign various waivers before he could go.

After all, the secret realm is different from the school grounds. If you fight with someone here, it will at most be a minor skirmish, and the probability of someone getting killed is very low.

But things are different outside of school. Xiande is known for its "simple and honest folk customs" from the city center down to the towns, and the school won't care if something happens.

"Your vacation... I can't approve it." Liu Qing scratched his shiny bald head and said with a serious expression.

Chen Yi asked, puzzled, "Why?"

Liu Qing looked at Chen Yi: "Some of the loans you're carrying are related to the school. It might be difficult for you to leave the school until you've paid them off. This is also for your safety..."

Chen Yi's eyelids twitched violently.

Good grief, you're protecting me because you're worried I'll die and become a bad debt, right?

“Then I have to go?” he asked.

Liu Qing pondered for a few seconds and then offered his suggestion: "You can go to the principal's office yourself. If you can persuade Principal Ma, then I have no objection."

"Why do you have to go to the secret realm so early? With your grades, it wouldn't be too late to go after the Immortal Examination, would it? At the very least, you can take out a loan after you go to the Immortal Cultivation Academy and buy the Foundation Establishment Pills together, wouldn't that work?" He persuaded Chen Yi a few more times.

But the latter remained adamant.

The 100-day foundation-building plan won't even last until the immortal exam is over.

Moreover, he is now about to establish a Heavenly Dao Immortal Foundation, and such a foundation requires a great deal of preparation and planning, so he must start preparing as early as possible...

A moment later, Chen Yi went directly to the principal's office.

"Knock knock knock!"

"Enter!"

The restriction on the door was lifted, leaving a gap just wide enough for one person to enter.

As Chen Yi entered the large office, memories from the past flooded his mind.

The tea room, antique calligraphy and paintings, and antique decorations, accompanied by a refreshing sandalwood scent, reached Chen Yi's ears as Principal Ma's voice said, "Come here."

But Chen Yi couldn't see the other person.

Because the office occupies more than 1,000 square meters and is divided into various areas, for a moment no one knew where the principal was.

The voice just now was the principal's spiritual transmission, as if he were speaking into Chen Yi's ear, and it was incredibly clear.

Chen Yi walked along the passageway filled with antiques for a long time before finally seeing Principal Ma at a table.

The other person is drawing a talisman.

Who knew this old man could draw talismans?

In fact, as the principal of Xiande School, he is capable of much more than just drawing talismans.

It is no exaggeration to say that he knows almost all six arts of cultivating immortality, only his mastery of them varies.

Just from the act of drawing talismans, Chen Yi could tell that the talismans drawn by the principal were not simple and were definitely not level 1 talismans.

"Chen Yi, I heard you want to ask for leave to go to the secret realm?" Principal Ma asked.

Chen Yi was slightly surprised. Did Liu Qing tell him?

Or is the entire school under his surveillance?

He nodded, feigning composure: "Mm."

"But your debts..."

The principal raised his head with a smile, revealing deep forehead wrinkles.

"You did very well on this monthly exam, so I don't intend to make things difficult for you. Let's get straight to the point."

“The secret realm you’re planning to go to has a spiritual herb called Nine Nether Grass. If you can find one for me, I’ll pay off all the money you owe. You can also sell me any extras; I’ll buy them all.”

The principal stared at Chen Yi, waiting for his answer.

"Nine Nether Grass?" Chen Yi murmured.

Since Principal Ma was able to mention it, it proves that this is an extremely rare herb, perhaps only found in that secret realm.

That secret realm can only be entered by cultivators at the Qi Refining stage...

After a moment's thought, he nodded and said, "Okay."

He didn't ask why. If the principal wouldn't say, then he shouldn't ask any more questions. He had that much insight.

Moreover, by investigating what the Nine Nether Grass is used for, it's easy to guess some things.

"Hahaha! Very good! You can have this talisman."

The principal put down his talisman brush, flicked his finger, and the talisman he had just finished drawing on the table quietly floated up...
