In the Sutra Library at Yuqing Temple in Penglai, Luo Yan finally thought of his words and started to explain them to Shi Liuli in a long speech.

There are different levels of cultivation, and each level has its own special significance.

The Qi Refining Stage refers to the process from opening up the Qi Sea to completely filling the Qi Sea, which requires a lot of time to draw Qi into the body for refining.

The marrow cleansing stage refers to the process of, after the Qi sea is filled, penetrating the true Qi into the limbs and bones, cleansing the meridians and channels, and refining the bones and marrow. This stage can greatly enhance the cultivator's physical fitness and prolong his life to about 200 years.

The Huafu Stage refers to transforming the Dantian around the Qi Sea into the Purple Palace, and condensing the true Qi in the Qi Sea into true essence, thus laying a good foundation for the subsequent key "true essence condensation".

Generally speaking, the Qi Refining stage takes the longest time, ranging from more than thirty years to more than sixty years.

The marrow cleansing stage takes the shortest time and can usually be completed in less than ten years.

As the most critical step in foundation-building, the timing of the Huafu Stage is very flexible.

Theoretically, it only takes an average of five years to build the Purple Palace, and the remaining time is only used to further improve the Purple Palace and purify the true essence.

But if the latter is omitted, and one attempts to form the elixir right after building the Purple Palace, there is almost a 100% chance that one will not be able to withstand the elixir-forming tribulation.

There are nine grades of elixirs, with good and bad grades clearly distinguished.

For those who are at the Huafu stage for less than a hundred years, even if they can survive the golden elixir tribulation, the highest golden elixir they can form can only be of the lower seventh grade. They will never be able to form an infant in the future, which means their lifespan is locked.

So everyone should invest as much time as they can in the Huafu Stage...

"So what exactly do you want to say?" Shi Liuli asked impatiently.

Luo Yan smiled slightly and said:

"Sister, that's why some people would definitely want to skip the Qi Refining Stage and go through the Marrow Cleansing Stage as quickly as possible, thus saving more time to go through the Palace Transformation Stage and improve the quality of the final Dan Formation Stage as much as possible."

"If my calculations and analysis are correct, this Li Palace should be a secret place that allows people to jump from Qi Refining to Marrow Cleansing, or directly enter the Transformation Palace from Marrow Cleansing... In this way, it makes sense why Senior Brother let this word slip."

"Your guess makes some sense." Shi Liuli thought about it carefully and it did make sense. He looked at him in surprise and said, "I didn't expect you to be so smart, Junior Brother."

"I'm not smart, I'm just used to thinking a few steps further than others." Luo Yan immediately said modestly, his squinting expression making him look extremely harmless.

[Hypocritical personality, synchronization value +1. ]

"Really?" Shi Liuli said innocently, "Never mind, I'll use your conclusion first, and then try to get the senior brother to say something!"

After saying that, she got up and ran away excitedly.

Luo Yan looked at her back, his narrowed eyes just covering up the brilliance in her eyes.

This Miss Shi is not stupid, she even knows how to use tricks.

She's smart, but she's also innocent and cute.

She is indeed a good fat sheep...well, I mean, a lovely young lady.

After seeing Shi Liuli off, Luo Yan returned to the workshop and continued to refine his cauldron-making technique and complete the assignments assigned to him by Elder Shi Ding.

The so-called tripod is a bronze utensil with three legs and two ears. It was originally a cooking utensil used for cooking meat, and later evolved into a magical instrument for setting up formations.

It is recorded in myths and legends that in the past, the earth veins cracked and connected directly to the Nine Springs, and countless ghosts broke into the world from the Netherworld. Finally, Shennong collected gold from the Nine Provinces to cast Nine Cauldrons, and set up a great formation for the world, using the Nine Cauldrons to suppress the Nine Provinces, thus separating the Netherworld and the human world again.

The Shennong Ding here is an innate spiritual treasure of the same level as the Nuwa Stone and Fuxi Sword, and is used to suppress the core of the Jiuzhou Formation.

This time, the assignment that Elder Shi Ding gave Luo Yan was the "Quicksand Net" that Lou Zhizheng had used before, a kind of portable tripod used to trap enemies.

First, you need to cast a small tripod, about the size of a palm.

The bottom should be square and the mouth should be round, which means "round like the sky, square like the earth". It should be shaped like a pot or a human body.

Then cut out three layers from top to bottom, symbolizing the upper, middle and lower dantians.

Finally, engrave the formation in it, connect the lower and upper parts, draw the lines carefully, and infuse spiritual power steadily.

In this way, the tripod is completed.

Huh! Luo Yan let out a long breath and began to examine the tripod in his hand.

This thing is called Quicksand Net. After activating it and throwing it on the ground, the tripod will sink into the ground and a nine-foot-long formation area will immediately form around it.

Once falling into the area, the enemy will continue to sink and be trapped, as if the ground has turned into a quagmire and can no longer move.

Of course, as a very low-level formation, the weakness of the Quicksand Net is its water-based magic.

"Xiang" says: A marsh without water is a trap.

If the Quicksand Net encounters water-based magic, the formation image of "water under the marsh" will be reversed, and its ability to trap people will be destroyed.

After reviewing the production process again, Luo Yan confirmed that there was really nothing that could be improved on this thing.

After all, he has the talent of "understanding a thousand things after hearing one thing" added to his physique. He can understand all kinds of scriptures at a glance and remember them all. It is naturally not difficult for him to make this kind of low-level cauldron perfectly in one go.

Well, in this way, I can make a few tripods and give them to Qiu Changtian and Ling Yunpo so that they can carry them with them.

Taking it out for self-defense at critical moments is like having an extra trump card.

Just as Luo Yan began to silently calculate what kind of cauldron formation was needed to coordinate Qiu Changtian and Ling Yunpo's battle system, he heard Shi Liuli's excited voice from a distance:

"Junior Brother! Junior Brother! Senior Brother has admitted it! There really is such a palace, just as we guessed!"

"Oh." Luo Yan said very calmly.

Of course, under the hypocritical character's magic tricks, this kind of calmness gives people the feeling of being as stupid as Guo Jing.

"Task two! Task two!" Shi Liuli rushed into the workshop, grabbed his shoulders and shook him, "Help me find out what secret realms there are in the palace, and how to pass the trial!"

Luo Yan: ...

So I am neither Doraemon nor an encyclopedia. Miss, you come to me for all your questions. Am I thinking too highly of me?

"Do you think the palace was built in flames?" Shi Liuli sat carelessly on his desk and speculated, "So do we need to prepare some fireproof magic tools?"

"Well, it's very likely." Luo Yan thought to himself that according to Xu Changqing's statement, this Li Palace used the spiritual power of the underwater volcano, so there must be some fire levels.

"When will the palace be opened?" Shi Liuli asked again, "Next month? At the end of the year? Next year?"

Luo Yan thought for a long time after hearing this, and then under Shi Liuli's expectant gaze, he slowly said:

"I think I should ask the senior brother about this."

"Idiot!" Shi Liuli patted his head. "If Senior Brother would answer so honestly, why would I come to you?"

"So in Senior Sister's heart, I am just Senior Brother's backup?" Luo Yan immediately acted sad.

[Hypocritical personality, synchronization value +1. ]

"Ah, that's not what I meant!" Shi Liuli immediately felt a little embarrassed and quickly explained, "No, Junior Brother."

"Because my senior brothers and sisters know the answer, and my father told them not to answer, I came to you for help. You will definitely help my senior sisters, right?"

She moved her pretty face closer, blinked her big eyes at Luo Yan, clasped her hands in front of her chest and shook them back and forth vigorously, making an expression of "please!"

Luo Yan suddenly blushed and quickly looked away awkwardly.

He is not a novice who has never seen a beautiful woman. No matter whether it is Xu Yinglian, who is as cold as a snow lotus on an iceberg, or An Zhisu, who is as gentle as a water lily by the lake, they are not inferior to Shi Liuli in terms of appearance and temperament.

But the girl's innocent and lively personality was really hard for him to resist - he felt like he was dreaming back to his youthful high school years, and had an ignorant feeling of falling in love with his cute female classmate.

Um, wait!

Luo Yan was suddenly awakened from his beautiful thoughts.

I actually fell for it, this Miss Shi... could it be that she has an aura that lowers her intelligence?
