After walking around the Li family's villa, Fang Tianyou also had a general understanding of the Li family's guardian formation. Although Zhou Chang strongly admired how hard his master had worked to set up the formation back then, how magical this formation was.

Fang Tianyou knew that this was just a crude spirit gathering formation, because it could gather the spiritual energy of heaven and earth, so people would feel refreshed when they walked here. And because the aura of heaven and earth is rich, it is naturally difficult to gather evil qi and yin qi, so it has a trace of purifying the body and mind. These were all regarded as evidence of the Li family's supernatural guardian formation.

This kind of formation, placed in the world of cultivating immortals, is the formation that some junior apprentices put down when they first learned to set up the formation, just like the model of the house built by children with building blocks, although it has its shape, but it has no god.

In the eyes of a true immortal cultivator, such a formation has no practical value at all. It's just that in a situation where cultivation resources are scarce and cultivators are low in cultivation like the earth, people who can really set up formations are already considered powerful people.

"The terrain here is good, and it's easy to gather the aura of heaven and earth. Chen Juzhai also added sixteen array eyes, which seemed a little cumbersome, and it was suspected of adding to the snake. If you want me to set up the formation, only eight formations are enough. Fang Tianyou secretly weighed himself in his heart, but he didn't break these things in front of Zhou Chang.

"Mr. Fang, can you see that there is something wrong with this formation of our Li family?" Seeing that Fang Tianyou was silent, Li Mengjia couldn't help but step forward and took the initiative to ask.

"Yes, how could there be a gathering of evil qi in the Li family's main mansion before Mr. Fang, could it be that there was something wrong with this formation laid by my master?" Zhou Chang then remembered that he only cared about praising his master's formation, and completely forgot that there was a loophole in this formation.

"To be able to arrange such a spirit gathering formation, only your master should be able to do it on Hong Kong Island. However, he also ignored a detail when arranging the formation, so he was caught by others and easily changed the formation, so that he was invaded by the evil qi. Fang Tianyou replied.

"What, my master's formation has really been changed?" Zhou Chang exclaimed. If he hadn't seen Fang Tianyou's methods, he would definitely scold Fang Tianyou for talking nonsense.

Now he is already convinced by the other party's Tianyou, Fang Tianyou's words, of course he believes it. What's more, Fang Tianyou's first sentence also seemed to fully affirm the status of his master Chen Juzhai's Hong Kong Island and the extraordinaryness of this formation.

Of course, he didn't know that Fang Tianyou specifically pointed out that it was not bad on Hong Kong Island, implying that if it was in the Immortal Cultivation Realm, such a formation was simply not worth mentioning.

"When your master arranged the formation, he didn't hide the formation eye, and ordinary people couldn't find it, but those who knew the formation could find it, and once the formation eye was broken, or the formation eye was changed, the formation would also change. Fang Tianyou said.

"Is there any way to remedy that?" asked Li Mengjia eagerly. Zhou Chang also looked at Fang Tianyou expectantly.

"Yes, but I need some materials. Fang Tianyou said.

"Then let's go to the underground secret room of our Li family. There may be materials that Mr. Fang needs. When Li Mengjia heard this, she hurriedly said.

The three of them immediately walked back to the main house and contacted Li Shicheng. Li Shicheng didn't say much, and immediately took Fang Tianyou to the basement of the Li family.

This basement can only be opened by Li Shicheng, Li Yingyu, and Li Yinghuan. Li Shicheng once gave Chen Juzhai the key, but he didn't ask for it, anyway, as long as he needs it, the Li family will definitely be successful, what is the use of the key.

The basement is divided into three floors, the first floor is some high-end household items, and the second floor is more valuable, in addition to gold bars and nuggets, there are also a lot of jewelry and antiques.

As for the third floor, it was built very hidden, if it weren't for Li Shicheng leading the way, Fang Tianyou would have found that there was still a floor in the basement without using his divine sense.

"Inside are some items that the Li family has collected over the years for Chen Tianshi and other cultivators to use, except for me, only Chen Tianshi knows about this third-layer mechanism. Li Shicheng introduced as he tapped three times with his cane at the foot of the wall in front of him.

Fang Tianyou's eyes were sharp, and he saw that Li Shicheng was not random and messy. The three points are regularly distributed in the three corners, and if they are connected, they are exactly the three vertices of an equilateral triangle, and under the unfolding divine sense, Fang Tianyou further discovered that in that area, there is exactly a triangular switch button.

With Li Shicheng's tap, the wall in front of him retreated to both sides, revealing an instrument like an ATM, Li Shicheng stepped forward, clicked a string of numbers on the keyboard, and opened a door three meters to the right of the instrument. Fang Tianyou knew that this was the Li family's underground secret room.

"Mr. Fang, please!" Li Shicheng gestured to Fang Tianyou. Fang Tianyou was not polite, and walked inside first.

Walking into the underground secret room, I found that the things here are really dazzling, which can be roughly divided into various types such as elixirs, medicinal materials, ores and metals, weapons and armor, jade, etc., and there are other things that are placed casually, and perhaps even the Li family themselves can't distinguish the categories.

There are so many strange things, placed together, fortunately, the ventilation in the secret room is quite strong, so there is no peculiar smell.

"Mr. Fang, you pick slowly, and you can take anything away. Li Shicheng is very satisfied with his collections, and even Chen Juzhai often visits here to get a lot of things.

He believed that as a fellow cultivator, Fang Tianyou would definitely be surprised by the abundance of the Li family's secret room collection, but when he peeked at Fang Tianyou, he found that this young man actually looked very calm, and there was even a little disappointment in the corners of his eyes, which made Li Shicheng feel even more unfathomable about Fang Tianyou.

"Okay, I'll take a casual look first. Fang Tianyou replied indifferently, and then walked towards the middle of the secret room. He was indeed a little disappointed in his heart. originally thought that with the family background of the richest man on Hong Kong Island, he would definitely be able to collect a lot of good things, but in fact, although there are many things here, there are few things that Fang Tianyou can look at.

"Even if the Li family is the richest man, it is only a secular family after all, and it has only risen for a hundred years, in terms of cultivation resources, where can it be compared with the cultivation family and the various sects of Daomen martial artists. Fang Tianyou sighed secretly in his heart, it seemed that he had too high requirements for the Li family's underground secret room.

Although he was a little disappointed, Fang Tianyou was not in a hurry to quit the secret room. Just now, he used his divine sense to probe, but he only knew the contents in general, and he wanted to explore more carefully and try to get as many useful things as possible.

Even if you can't find anything of great value, you have to take a few things that are barely eye-catching, and under the lack of cultivation resources, many Eastern and Western Heavenly Blessings have to retreat to the second.

Fang Tianyou walked to the medicine cabinet containing all kinds of flowers, leaves, fruits, and even dead branches, and did not take the centuries-old wild ginseng, nor did he touch the elixir in the jade bottle, but chose an inconspicuous nameless root and a tuberous rhizome, which were good medicinal materials that could be used as alchemy condiments.

As for those weapons, armor, and jade, they were directly ignored by Fang Tianyou. Those weapons and armor may be very tough and sharp for ordinary people, but for Fang Tianyou, who is an immortal cultivator, they are nothing.

And those few pieces of jade, Fang Tianyou didn't find any spirituality in them, this may be a valuable jade in the world, or even a good jade recognized by ordinary cultivators, but it is useless to Fang Tianyou.

However, among the metal ores, Fang Tianyou found three pieces of black ore. Although these three stones are not precious stones, they should come from the 10,000-meter deep sea.

Under the bottom of the 10,000-meter seabed, after tens of millions or even hundreds of millions of years of seawater extrusion, the ocean current washes out, even ordinary stones, they will become extremely hard, and contain a trace of water spiritual charm, which can be used as formation materials, especially formation materials related to water and relations.

In addition, under Fang Tianyou's careful investigation, he actually found another thousand-year-old Yin Accumulation pine wood in the ore pile. This thousand-year-old pine wood looks like a long strip of ore, so it was placed in the ore by the Li family and Chen Juzhai.

Fang Tianyou only thought it was a little weird when he first looked at it, but after careful investigation just now, he found that this was actually not an ore, but a piece of thousand-year-old pine wood. Pine wood is originally yin, and the yin building blocks that have become after being buried underground for thousands of years can be completely comparable to the Yin Xuanshi, the superior material of the formation in the immortal cultivation world.

In order not to arouse Li Shicheng's doubts, after Fang Tianyou picked these things, he did not immediately put them in the storage ring, but threw them in an empty bag next to him and took them out.

Li Shicheng saw that Fang Tianyou was taking some inconspicuous things, thinking that Fang Tianyou was embarrassed to take more, and persuaded Fang Tianyou not to pick others, especially the pills in the jade bottle.

The pill in the jade bottle, Fang Tianyou had already probed, and the best one in it was a gray pill with the same effect as a quenching pill and a bottle of small replenishing yuan pill.

Fang Tianyou felt that he didn't need it, so he didn't take it, and told Li Shicheng that it was enough for him to have these, but he just hoped that the Li family would help pay more attention to similar things he chose in the future.

In this regard, Li Shicheng of course agreed, he knew that the cultivator's actions were unfathomable, so he didn't force Fang Tianyou to take anything else.

After leaving the Li family's underground secret room, Fang Tianyou walked around the Li family's villa alone, repairing and changing the Li family's spirit gathering formation.

The reason why there was a gloomy aura in the sky above the Li family's main mansion was because someone moved the eye of the Li family's formation and tore a hole in the Li family's spirit gathering array.

Not only that, but the person who destroyed the formation also arranged a small gathering array in the yin place on the high ground north of the Li family, and teleported a wisp of yin and evil qi to the sky above the Li family's main mansion with a high and low momentum.

Fortunately, the arranger did not have a deep knowledge of the formation, and the arrangement of the gathering evil array was extremely rough, and the yin and evil qi transmitted was limited, otherwise the disaster suffered by the Li family would be far more than that.
