The fear of cultivating immortals comes from insufficient firepower

Without wasting any time, Li Xiaofan immediately turned into an afterimage and moved quickly inside.

After passing the first hall, Li Xiaofan didn't stop and immediately headed towards the square staircase.

Then he passed the three stone gates, but Li Xiaofan still didn't stop.

He didn't lie before. There was indeed danger behind the other two stone gates.

This should also be used by Master Mu Xingyao to deal with greedy monks.

Continuing to walk down, they soon came to the statue hall. Li Xiaofan jumped out of the pool without saying a word.

Finally, he returned to the main hall where Master Mu Xingyao was enthroned.

After arriving here, Li Xiaofan slowly walked to the futon where Master Mu Xingyao was sitting.

First sweep aside some walnut-sized stones around the futon, and then pick up the futon very carefully.

After the futon was completely removed, a very delicate disc with runes engraved on it was hidden under the futon. .

In other words, this is not a disc at all, but a cover protecting something.

Yes, Li Xiaofan actually discovered this thing before.

Including the cover below and the walnut-sized stones around the futon, they are not ordinary things.

The reason why he stopped Mu Xingyao from taking the futon was because he wanted to deceive others. Don't let this thing be discovered.

In fact, Li Xiaofan has been thinking about a question since he first entered the underground palace.

It is such a large underground palace, although the outer defensive restrictions, that is, the defensive formations that prevent others from entering, have completely collapsed.

However, some facilities in the underground palace are still operating normally.

For example, those stone gates, mechanisms, and guard statues.

In fact, all of these things can be regarded as one of the facilities of the underground palace, and if you want all of these things to operate normally, you must have an energy source to provide power.

For example, this underground palace is like a laptop.

Although the laptop's firewall and security system were down, anyone could break in.

But the computer can still be turned on, and some stand-alone games can still run.

Then it means that the battery of this computer is still charged, otherwise this laptop cannot even be turned on.

The energy source in this underground palace is equivalent to the battery of a laptop.

Now, Li Xiaofan has found the location of the "battery".

After a little research, Li Xiaofan immediately took out the secret book of talismans that Mu Xingyao had given him before, and started to read through it.

After a short time, Li Xiaofan's eyes lit up.

This secret book indeed contains something related to it.

After comparing them with each other, Li Xiaofan began to move the runes on the lid.

Not long after, there was a flash of light and the lid opened directly.

Then, Li Xiaofan saw under the cover a precise formation core, which could also be called the formation eye, emitting a strong aura.

The diameter of this thing is about one meter. If you look down, it looks like a compass.

The only difference is that there is a walnut-sized groove next to some very important runes at the core of this formation.

And in these grooves, there are dazzling spiritual stones, and these spiritual stones are the energy source of the entire underground palace.

The reason why Li Xiaofan went all the way back was for these things.

When he entered the treasure house before, Li Xiaofan saw three boxes of different sizes.

But among the three boxes, only one contained low-grade spiritual stones, and the other two boxes were empty.

Li Xiaofan felt strange at that time. Why are the boxes containing middle-grade spiritual stones and high-grade spiritual stones empty.

Li Xiaofan also thought that maybe Mu Xingyao's master needed a lot of spiritual stones to heal his injuries.

Therefore, I left the high-grade and medium-grade spiritual stones to myself, and the low-grade spiritual stones that were of little use to future generations.

But after arriving here, Li Xiaofan overturned this idea.

Because he saw those stones around the futon.

You know, those are not ordinary stones at all, but spiritual stones after the spiritual energy has been sucked out.

Li Xiaofan took a look and found that there were two types of spiritual stones that had lost their spiritual power, namely middle-grade spiritual stones and high-grade spiritual stones.

But the two stones look completely different.

The middle-grade spiritual stone was obviously quickly absorbed by the spiritual energy, causing the stone to crack slightly.

The stones left behind by high-grade spiritual stones are different and have no cracks, which means that the spiritual energy inside is slowly being consumed.

Later, Li Xiaofan discovered something different under the futon, and then made a bold guess.

Under this futon must be the location that provides the power source for the underground palace.

And those high-grade spiritual stones that have lost their spiritual energy were taken out and thrown here after their spiritual energy was used up.

Now it seems that Li Xiaofan’s guess is really right.

Looking at the spiritual stones at the core of the formation at this moment, although a lot of the spiritual energy in each spiritual stone has been used up.

But it is still thicker and purer than the middle-grade spiritual stone.

Just because the core of this formation are all genuine high-grade spiritual stones.

After counting, there were a total of eighteen high-grade spiritual stones.

"Haha, get rich, get rich."

Li Xiaofan shouted excitedly. He had won [-] low-grade spiritual stones before, and now he had obtained [-] high-grade spiritual stones.

Although these eighteen high-grade spiritual stones were somewhat discounted, they were already very good supplements for Li Xiaofan who was in the Qi training realm.

Quickly taking out the knife, Li Xiaofan began to pry out the high-grade spiritual stones one by one.

After each spiritual stone is taken away, its corresponding rune loses its light.

Not long after, all eighteen high-grade spiritual stones were in Li Xiaofan's hands.

Standing up slowly, Li Xiaofan really wanted to sing a song to express his inner joy.

However, as the old saying goes, when things go to extremes, they will be reversed, and when happiness becomes extreme, sadness will arise.

Just when Li Xiaofan was about to open his mouth to sing, the ground suddenly shook, and then cracks began to appear under his feet.

At the same time, the ceiling began to collapse, and even the statues above fell down.

Li Xiaofan was stunned: "Isn't it right? Without the spiritual support of the high-grade spiritual stone, will this underground palace completely collapse?"

After complaining, Li Xiaofan quickly put three life-saving charms on himself.

They are the divine walking talisman, the golden armor talisman and the divine power talisman.

Then, like a ghost, he quickly returned upwards.

I have walked back and forth several times, and I am very familiar with it.

Just after passing the three stone doors at the stairs, Li Xiaofan suddenly saw the stone doors on the left and right opened.

First, a beast-like roar came from the stone door on the left, and a zombie-like person walked out of it.

Behind the stone door on the right, some black mist began to float out.

Li Xiaofan was shocked: "Oh my god! There really are big rice dumplings! Uncle Jiu, help me!"

Perhaps because he smelled the breath of a living person, the big rice dumpling actually looked at Li Xiaofan.

Then a blood-red rune lit up on his forehead, and he chased after Li Xiaofan.

"Nima, you are dead, and you still come out to harm others, I will send you to a long sleep!"

Cursing angrily, Li Xiaofan opened his storage bag and took out hundreds of talismans.

He took out fifty sheets first and threw them towards the passage.

Fifty talismans erupted together. The terrifying explosion and scorching fire instantly completely collapsed the rear passage.

Not only did he sell a few big rice dumplings, but he also blocked the black poisonous smoke flying over...
