The aura cover completely enveloped Zhang Hao, squeezing through the water, opening up a passage for Zhang Hao to walk into the pool.

When he completely walked into the water, Zhang Hao breathed a sigh of relief and could breathe normally.

And the consumption of aura in "Water Avoidance" is not continuous, that is, when the aura cover is first formed, it consumes a hundred weeks of aura energy, and then as long as the aura is constantly running, the existence of the aura mask can be maintained.

Therefore, using "Water Avoidance", Zhang Hao can stay underwater for a long time.

Regardless of the "Water Condensation Technique" and "Water Control Technique", Zhang Hao felt that "Water Avoidance Technique" alone was worth four low-grade spirit stones.

Subsequently, Zhang Hao walked under the water and walked towards the location of the abandoned mine in his memory.

The deeper you go into the water, the dimmer the light becomes, but fortunately, you have the night vision ability of your eyes and can see your surroundings clearly.

This is also the reason why Zhang Hao has always practiced "Danshu Outer Dao Spiritual Eyes Part I", although the night vision ability is only an incidental mystery of "Danshu Outer Dao Spiritual Eyes Part I".

Seeing that the terrain under the water was completely destroyed, Zhang Hao guessed that the waterhole might have been formed by the waterfall.

Walking step by step, Zhang Hao saw a magical place, and walked over quickly.

This is the stone monument pedestal?

Zhang Hao saw that all the steles of the steles had been destroyed, and only the pedestals of the steles remained. Miraculously, the pedestal of these steles is still protected by a ban that separates the surrounding pools from the water.

Zhang Hao was a little puzzled, the monument was all destroyed, how could the pedestal survive? Look at the concave ground around it, you can see how powerful the force that bombarded this place was at that time!

Or, the prohibition left by those immortal cultivators at the beginning was not to protect the entire stone tablet, but only to protect the pedestal.

Thinking about it this way can explain why the comprehension +1 attribute comprehension exercise can be used on the collapsed stele in the first place, because the pedestal of those collapsed steles is still there, and the comprehension +1 attribute is the exercise comprehended from the pedestal, not in the broken stele body.

Of course, these are just Zhang Hao's self-righteous understandings, and they are not the most important.

The most important thing is that at this moment, a line of text inexplicably appeared in Zhang Hao's mind: Do you use the comprehension +1 attribute? It means that these pedestals can continue to comprehend the exercises!

Zhang Hao immediately thought of "yes", and a line of text inexplicably appeared in his mind: "Haotian Sect's Eleventh Layer Extension Exercise of Qi Training" is comprehending, 2/20.

At first, Zhang Hao didn't pay attention, he walked a few steps away, and then he reacted, the progress of this comprehension was not 200, but 20!

Zhang Hao watched it again, it was really 20 progress!

What's going on here?

Could it be that his golden finger ability has been enhanced? Zhang Hao shook his head, the three attributes of the golden finger have been used, and they are all +1+1+1.

It's not your own problem, it's the problem of the stele.

Could it be that the stele is only better understood after it is completely destroyed?

Or is it that the existence of the stele increases the difficulty of comprehension?

Zhang Hao couldn't figure it out, but this was a good thing for himself, he didn't comprehend the exercises in these stone tablets at the beginning, just because the comprehension progress was too scary.

Nine thousand, ninety thousand, nine hundred thousand, nine million! How many years will it take to comprehend!

Now that he has changed from 200 to 20 with one less zero, Zhang Hao feels that he can comprehend a few exercises in the stone tablet while looking for spirit stones.

Leaving the pedestals of the stone tablets standing one after another, Zhang Hao continued to move forward.

After walking for half a day, Zhang Hao saw a huge black hole under the water.

According to the location of the stone stele, this should be the Thousand Cave Cliff, and this huge black hole should be the abandoned mine road.

Zhang Hao walked in directly and saw the familiar main vein ore road, and then as he went deeper, he saw the holes of the branch vein ore road.

Among them, Zhang Hao is still very familiar with several cave entrances, and it was in this cave that he found three lower grade spirit stones.

Then Zhang Hao continued to walk forward, these holes had been screened at the beginning, and Zhang Hao still remembered it vividly.

Then I saw the entrance to the cave where six lower-grade spirit stones and one high-grade spirit stone were found!

Then I saw that I found twelve lower-grade spirit stones, three high-grade spirit stones, and a cave with even more high-grade spirit stones!

It was with these spirit stones that he broke through from the third layer of qi training to the seventh layer of qi cultivation before!

Continuing to walk forward, Zhang Hao began to use the Fortune +1 attribute, preparing to sift through all the holes in the mine!

It's a pity that after using the Fortune +1 attribute on the three holes in this place, all of them dimmed.

Zhang Hao walked to the next cave and sat down cross-legged, waiting for tomorrow to continue screening, there are still more than one hundred and fifty Bigu Dan and he is not in a hurry at all.

Every day after that, Zhang Hao continued to use the Fuyuan +1 attribute to screen the hole, and then went to the stone tablet pedestal to use the comprehension +1 attribute to comprehend the "Haotian Sect's Eleventh Layer Extension Exercise".

Until it took eighteen days to comprehend all the "Haotian Sect's Eleventh Layer Extension Exercises", Zhang Hao did not find a mine with spirit stones.

So Zhang Hao then began to use the comprehension +1 attribute to comprehend the "Haotian Sect's Qi Cultivation Twelve Layer Extension Exercise", 2/40, and the comprehension progress changed from the original 400 to 40!

It was also after so many days that Zhang Hao discovered that one of the shortcomings of "Water Avoidance Technique" was not a shortcoming, that is, the aura cover formed each time could only be used for one day, and the aura cover would slowly disappear after one day. Zhang Hao needed to consume another hundred Zhou Tian Spiritual Qi to form a new Spiritual Qi Cover.

In this way, the amount of spiritual energy for a hundred weeks can only last for twenty-four hours.

On this day, Zhang Hao finally made a discovery, after using the Fuyuan +1 attribute on the three adjacent caves, he saw that the hole on the left faintly emitted a faint white light.

Zhang Hao made a mark in front of this cave entrance and didn't go in, because this faint white light meant that the harvest was not large, at most a few low-grade spirit stones!

What Zhang Hao needs now is a high-grade spirit stone, especially a more advanced spirit stone, which is equivalent to a thousand days of penance when used once!

Zhang Hao wanted to quickly improve his cultivation! This was not something that a few or dozens of low-grade spirit stones could meet.

When you have nothing to do in the future, you can slowly find these low-grade spirit stones.

Next......

Sometimes the openings of the branch vein mine are relatively scattered, and Zhang Hao can only screen the cave entrances individually, not wanting to miss every opportunity to obtain spirit stones, maybe there are hundreds of more advanced spirit stones in this cave!

It's a pity that the harvest is still not very big, and three more holes that faintly emit a faint white light were screened out, Zhang Hao just made a mark, and still didn't go in to look for it.

So thirty-eight days passed unconsciously, and Zhang Hao comprehended the "Haotian Sect's Twelve Layers of Qi Cultivation Extension Exercises".

Subsequently, Zhang Hao began to use the comprehension +1 attribute to comprehend the "Haotian Sect's Thirteen-Layer Extension Exercise", 2/80, and the comprehension progress changed from the original 800 to 80!

Finally, on the next third day, Zhang Hao screened a hole and bloomed with dazzling light!

This dazzling light means that there are even more advanced spirit stones inside!

Zhang Hao was overjoyed, and immediately walked in, and when he came to the first fork, he saw the corpses of two thousand-eyed demon spiders in the water!

Zhang Hao was stunned for a moment, and then thought that all the thousand-eyed demon spiders in the mine should have been drowned alive!

With the momentum to move forward, Zhang Hao began to use the Fuyuan +1 attribute to screen and advance every day, and finally determined the location of the spirit stone before Bigu Dan finished eating, a mine road more than fifty meters long.

Zhang Hao immediately began to clasp the white spot material on the stone walls on all sides, looking for spirit stones.

The bottom stone wall was not found! The left stone wall was not found! The right stone wall was not found either! Finally, a white spot in the top stone wall was buckled, and it was a big lump!

In this big lump, there are twenty-four lower-grade spirit stones in the outermost layer alone!

Zhang Hao gently pulled down the twenty-four lower-grade spirit stones one by one, and saw six high-grade spirit stones. After gently pulling off these six high-grade spirit stones, he saw two more advanced spirit stones.

Zhang Hao returned to the pedestal of the stele with these thirty-two spirit stones, preparing to practice there well, and at the same time comprehend the exercises every day.

Of course, it is better to use two more advanced spirit stones first, and absorbing them once is equivalent to a thousand days of penance!

Zhang Hao had already seen that he had broken through to the eighth layer of Qi cultivation right in front of him!
