Maybe absorbing a million spirit stones, the total amount of spiritual energy can also be comparable to spirit crystals, but here's the problem.

Which is more efficient, absorbing millions of pieces or absorbing one piece?

For example, at a critical juncture, when the battery life is insufficient and 'needs to be charged urgently', still slowly suck a piece of spirit stone?

Even if it is to directly burst a large piece of spirit stone, the efficiency of crazy absorption is far less than the pleasure of directly absorbing a piece of spirit crystal.

Therefore, the aura in the spirit crystal may only be equivalent to a million ordinary spirit stones, but this thing is not at all qualified by low-level cultivators.

Generally, the big guy after the third order of Sendai will prepare a few pieces for himself in case of emergency!

It's a rare thing in the world of cultivating immortals, let alone the earth?!

After determining that the core of the formation was the spirit crystal, Lin Zixiao couldn't help but feel a lot of emotion in his heart: "It seems that the earth in the past is much more brilliant than I imagined. ”

"It seems that a planet that is far inferior to the Eastern Wilderness actually has the existence of spirit crystals, does this prove that there were also super spirit stone veins on the earth back then?"

"If there is a super spirit stone vein, it should be ...... At least it's enough to pile up a few Sendai high-level powers?"

"So, where did these people go?!"

It's weird!

Lin Zixiao frowned.

She couldn't figure out these questions.

First of all, the Earth is really small.

Of course, for ordinary people, the earth is incomparably huge, but for immortal cultivators...... You don't need to be invincible in cultivation, as long as you are above the Tribulation Period, you can master the method of teleportation by cultivating.

At that time, a teleportation can be carried out from one side of the earth to the other side of the earth.

Is this a planet big?!

But on such a planet, there have been top-level spirit stone veins, and there should even be several Sendai high-level and even true immortal existences?!

Although Lin Zixiao had never seen these 'powers', it was enough to see a lot of problems by calculating the spiritual energy content of the earth at the beginning through the spirit crystal.

So, where did these people go?

Why did the earth become less powerful more than 2,000 years ago, and even gradually deplete its aura?

Could it be that they are all gone?

But here comes the problem again!

If those great powers are gone, how can the spirit crystals in front of them be left on the earth? This is a very useful existence for the big guys after the third order of Sendai.

From the cultivation realm outside of the earth or from other cultivation worlds?

Then the problem arises again.

Judging from these reliefs, the First Emperor was an ordinary person before he ate the 'elixir', how could he be able to get the spirit crystal?

Powerful under your hands?

Again, how awesome are ordinary people's subordinates? Can they get spirit crystals back from outside the territory???

Why did he submit to the First Emperor if he was so awesome?

Personal charisma?

It can't be that the first emperor is a pyramid scheme, right?

At every turn, he said 'understand the applause', and then the immortal cultivators at that time were very 'simple', and they were brainwashed by the First Emperor without warning?

It's unlikely!

There are too many mysteries in this, which makes it difficult for Lin Zixiao to understand at this moment.

Fortunately, at this time, Zhou Chuan's voice came from the walkie-talkie in Lao Chen's hand: "Lao Chen, we have all come out." ”

"Stay away!"

Lin Zixiao spoke.

"Stand away. Old Chen Tou repeated: "By the way, how far to retreat?"

"A hundred feet away. ”

"Three hundred meters away!" Old Chen nodded and said to the walkie-talkie.

"Okay, we'll get back right away. ”

......

Outside the dungeon.

Zhou Chuan quickly retreated with a vote of people, and Liu Gang also beckoned the people from the Residents' Happy Life Department to fly back, while closely protecting Zhou Chuan and his party.

As for whether it is 'protection' or 'care'...... Is there a difference?

After exiting more than 300 meters away, they gradually stopped, but Liu Gang still felt unsafe, and said directly: "Retreat another 200 meters!"

"I always feel like it's going to be a big move!"

“...... Good!"

Zhou Chuan was silent slightly, and then led the people back again.

It wasn't until they exited about 500 meters that they stopped and informed Lao Chen Tou through the walkie-talkie.

The news is out.

Zhou Chuan looked at the shadow of the dungeon in the distance, and couldn't help but sigh: "Alas!"

"It's a pity that a place like the Mausoleum of the First Emperor has only been seen for less than a day, and it will be completely reduced to a historical ......"

"It's a pity!"

He thumped his chest.

When Liu Gang heard this, his eyes were firm, and he said casually: "The past does have research value, but the future is our destination!"

"For a better future, a dungeon that has been emptied, what about destroying it?"

"Besides, you've already recorded what should be recorded, haven't you?"

After Zhou Chuan heard this, he stopped talking.

The past and the future, which one should be more emphasized, he can still distinguish clearly.

But as a person who has dedicated most of his life to the cause of archaeology, it is impossible to feel comfortable when encountering this kind of thing.

......

Inside the coffin.

Lao Chen put the walkie-talkie into his trouser pocket: "Okay, I'll break the formation now!"

"Don't say it, these two formations are really interesting......"

As he got started, he said to Lin Zixiao: "I don't know the names of the formations, but according to the effect, I call them the 'Suspended Formation' and the 'Solid' Formation. ”

"The suspended formation can make this Blue Falling Nine Heavens and the 'Sea of Stars', as well as the coffin, the ladder, etc., all suspended in the air. ”

"Stabilize the formation, so that even if more than two thousand years have passed, this underground palace has still not collapsed, and there have never been any structural problems!"

"There's even an effect similar to 'Sumeru mustard seeds' hidden in it, if I can study it thoroughly......"

The corners of Lao Chen's mouth hooked, the work in his hand paused slightly, and he looked at Lin Zixiao: "You say, can I engrave these two formations on my body?"

"If I can, then can I 'levitate' on my own? That is, I can fly on my own, even if my cultivation has not reached that point!"

"At the same time, is my physical body still stable even after thousands of years? Or can I have some of Sumeru's abilities in mustard seeds, such as making my body bigger and smaller? These are not the abilities that monks in the Qi Refining Period, Foundation Building Period, or even the Jindan Stage have, right?"

"If you can......"

Old Chen was a little excited.

He thought these formations were very interesting, but at the same time, he wasn't sure if they would work out!

Although they are all 'cultivating immortals' or 'cultivating truth'.

Judging from what Lao Chen Tou has learned so far, these formations that 'Lin Fan' gave him are somewhat different from the 'formations' in the Mausoleum of the First Emperor...... It's pretty obvious.

However, he didn't think about the direction that these formations came from the two worlds, but felt that it was likely that this was from two different 'sects', or that there was some gap between the 'systems' of the two sides.

So, can the formations of other systems be engraved on the body?

When Lin Zixiao heard this, he couldn't answer for a while: "......"

"It should ...... Is that okay?"

"But you have to be more sure to carve these formations into your body, otherwise if something goes wrong, it's going to be a big problem. ”

"That's for sure. ”

Lao Chen grinned: "I have taken pictures and recorded them, although I only took photos near the core, but the entire underground palace and the Residents' Happy Life Department have taken detailed photos more than once." ”

"When this is over, I'll go back and study it!"

"Now...... You have to be ready. ”

He shook his head: "Although my old man can be regarded as a Taoist, but there is a poor spirit gathering array on his body, once the formation is broken, the underground palace will definitely collapse instantly, but don't let my old man be stoned to death." ”

"Although the feng shui of the Mausoleum of the First Emperor is definitely very good, I haven't lived long enough......"

“......”

Lin Zixiao suddenly wanted to laugh: "Don't worry, you can't die." ”

She couldn't laugh or cry.

This old man really likes to joke.

At this time, what else is there to talk about Feng Shui......

But then again, is Feng Shui really good here?

Logically speaking, it must be good, after all, there are many capable people under the First Emperor, although there is no detailed record, but it will definitely not be bad.

But the question is, no matter how good the feng shui is, hasn't the grave been dug up?

Thundered!

Between thoughts.

The formation was broken by Lao Chen's head, and the entire underground palace began to shake in an instant, the giant coffin fell violently, and the 'stars' in the sky disappeared directly, and the originally amazing ladder also fell down one after another.

The sky is falling apart!

It was as if at this moment, the sky had fallen.

"Let's go!"

Lin Zixiao's face remained unchanged, he wrapped his true yuan around Lao Chen's head, grabbed the spirit crystal with one hand, and then the purple qi spread out!

Syllable!!!

The falling giant coffin suddenly stopped in the air, and then was enveloped by purple qi and turned upside down, shining Lin Zixiao and Lao Chentou in it.

"!!"

With a shout, Lin Zixiao urged his true yuan to the extreme!

The giant coffin was heavy, but it was not enough for Lin Zixiao to be unable to move it today, but the problem was that there was still a large amount of earth and rocks falling on it.

Bang, bang, bang!!

The dull collision sound sounded one after another, and Lao Chen's head was directly shocked to the point of dizziness, and Lin Zixiao clearly felt that the giant coffin was getting heavier and heavier.

Sweeping through the divine sense, one can clearly perceive that a large number of heavy earth and stones fell from the sky and fell directly on the coffin, and at the same time, more and more, more and more heavy......

"Cover your ears!"

Lin Zixiao spoke.

Old Chen was already dizzy, and at this moment, he was obedient and covered his ears.

"Gone!"

At this moment, Lin Zixiao's right fist shone with golden light, and then ......

While!!!!

Hula!

The giant coffin suddenly rose to the sky, breaking through the 'collapse' obstacle!

Lin Zixiao wrapped Lao Chen's head with True Yuan, followed closely under the giant coffin, and rose to the sky.

......

"Collapsed!"

Zhou Chuan watched the mountain in front of him collapse suddenly, and only felt that his heartbeat was paused for a moment.

However, Liu Gang ignored him, and stared at the area where the smoke and dust were billowing up: "That one is not going to be okay, right?"

Bang!

The thought had just risen.

Liu Gang saw that the mountain, which was originally collapsing rapidly, was directly 'blown up'!

Then, a huge coffin rose into the sky.

Immediately after, purple qi permeated out, even if it was covered by billowing dust, it was still dazzling.

"Sure enough......"

"I wonder when I can be so strong?"

Liu Gang is looking forward to it.
