This means that the age of these stone milks is very likely to be close to 10,000 years.

Hiss~~~~

Such a discovery suddenly made Zhou Feng couldn't help but gasp.

This is a 10,000-year-old stone milk that is about to become the leyline gold liquid, and it can easily create a terrifying elixir for the innate powerhouse!

Just imagine, in the entire Chu State, it is estimated that there are tens of thousands of martial artists whose strength has reached the peak of the tenth layer of internal qi, but almost 99.9999 percent of these people are impossible to go further.

So many people have worked hard for almost tens or hundreds of years, all of them are working hard to break through the innate nature, but this few drops of leyline gold liquid can be easily completed, and the gap can be imagined.

If these leyline gold liquid appeared in the Lichu Kingdom, I am afraid that the entire Lichu Kingdom would be a mess, and countless people would be killed in order to fight for it.

And it is this leyline gold liquid that is about to be completed, but Zhou Feng is now at his fingertips!

Trembling, Zhou Feng slowly stretched out his hand to those white and golden stone milk, the excitement in his heart could not be expressed in words, if all the transformation was completed, it would be a huge wealth that the world did not dare to imagine.

This is not as simple as one drop or two drops, but a whole small half of the pool, if this is converted into drops, it is estimated that it will be tens of thousands, how many innate powerhouses can this create!

Zhou Feng's mood at this time was really excited, there were only dozens of innate masters in the entire Chu Kingdom, and there might be some innate powerhouses hidden in the dark, but this innate powerhouse must be a handful.

If all these leyline gold liquids are used to create innate powerhouses, even if the success rate is low, it will be enough to create no less than dozens or hundreds, so I am afraid that the entire Chu Kingdom will tremble.

Airplanes~~~

But just when Zhou Feng was excited and wanted to touch the leyline gold liquid, suddenly an invisible faint halo flickered, and Zhou Feng only felt that his hand seemed to be blocked by an invisible diaphragm, so that he could not move in at all.

"What's going on?"

The expression on Zhou Feng's face froze instantly, and the little joy that had just flashed disappeared without a trace in an instant.

"Protective Formation!"

His reaction was not too slow, and he immediately understood what was going on.

This leyline gold liquid is so precious, and this cave shows a lot of man-made traces, obviously this leyline gold liquid has long been discovered and protected.

Zhou Feng didn't dare to say that no one had really come in this cave for many years, but this leyline gold liquid had always been placed there safely, not only did it not decrease, but it accumulated more and more, which already showed the strength of this protective formation.

Zhou Feng had the intention to attack, and wanted to try the power of the protective formation, but he was a little worried that this formation was not a simple protection, and it was very likely that he would fight back.

Judging from the layout of this cave, I am afraid that the former owner here was at least an innate powerhouse, so how could the protective formation that the innate powerhouse could crack by a small martial artist of the tenth order of qi.

Zhou Feng didn't try, although he felt a little pity, but he still chose to give up, although the leyline gold liquid was precious, but Zhou Feng didn't feel that he couldn't break through the innate nature, so he gritted his teeth and forced himself to forcibly retreat, walking towards the depths of the cave.

For the first time in the darkness, those cold eyes fluctuated slightly, and it was unknown whether they were surprised, contemptful, appreciative, or whatever.

Zhou Feng naturally didn't know this, and still walked to the depths of the cave.

The area of this cave is very large, except for the small pool where the leyline gold liquid is stored, there is nothing too conspicuous, when Zhou Feng walked a few steps deeper, he entered a small compartment, this compartment is not large, but it is empty, except for a stone table, two stone benches are placed in it, there are some cold and hard stone walls all around.

Zhou Feng slapped it a few times, making a dull sound, feeling that the stone walls were all solid, as if there was no secret room behind the stone wall.

On the stone table, there is a chess board of Go, and this game is an endgame.

"Endgame?"

Zhou Feng looked at this endgame, and then looked at everything around him, except for the stone wall, there was a stone wall, and this endgame was extremely abrupt, obviously this problem should appear in this endgame.

Zhou Feng knew a little bit about Go, but he was not proficient in it, and after a brief observation, he found that white chess had an absolute advantage, and was about to kill the big dragon of black chess and completely lay the victory.

Similarly, looking at this black chess, even a stinky chess basket like Zhou Feng can see that there is almost no chance of survival, and he will definitely lose!

This...... What's so funny?

Zhou Feng smiled bitterly, what metaphor can be in a chess game that has already been doomed?

Zhou Feng felt a trace of suspicion in his heart, there was nothing else around, and this endgame was obviously placed here for someone to crack, but the ending was doomed, what else was there to crack?

"How many tricks to try?"

Zhou Feng had such a thought in his heart, and touched the white chess, as long as he destroyed the big dragon of the black chess, he could win, but found that the white chess was ...... I can't take it!

In desperation, Zhou Feng went to try the black chess again, which was easy to pinch, and it seemed that it was time for the black chess to go first.

"Where to put it?"

Looking at the very clear result on the chessboard, Zhou Feng seemed extremely hesitant, it was inevitable that Dalong would be slaughtered, the victory or defeat was already doomed, and any struggle was in vain.

struggled several times, but Zhou Feng never put down this particle, there was really no need to struggle, and then Zhou Feng threw the chess piece back to the chess cup, and the throw conceded!

Click~~~

Almost at the same time as Zhou Feng admitted defeat, the chess cup suddenly sank suddenly, and then Zhou Feng's ears heard such a clicking sound, and the source of the sound was - under his feet.

The bottom of this cave is paved with a hard bluestone, and at this time, the stone table where the endgame is placed is automatically divided into two pieces with the dividing line in the middle of the Go board as the middle line, and the ground under the stone table has cracked a one-person-wide crack at this time, revealing the dark passage below, and only the outermost steps can be faintly seen.

"The ...... of this mechanism"

It's not a clever design, but it's a bit of a surprise.

The stone table is made of two pieces, but the splicing is seamless, Zhou Feng has also observed the stone table, and even tried to push the stone table, but it has never been successful, but he didn't expect that the stone table was separated from the middle.

If this pushes the stone table, it is equivalent to exerting force in one direction, not to mention whether it can be pushed or not, and the wrong direction of the force alone is doomed to make no discovery.

As for the endgame, that's just a simple test!

It is important to judge the situation, but knowing that you are going to lose but still have to struggle, not to mention the futility, and a lot of time is wasted.

The design of the mechanism is very simple, but Zhou Feng believes that there will not be many people who can really crack this mechanism, and he is also lucky, his chess skills are too poor, and he did not deliberately force it, but he got a bargain.

Looking at this swarthy hole, Zhou Feng was silent for a moment, and then walked towards the cave entrance.

This cave is becoming more and more mysterious, refining the heart path, earth vein gold liquid, etc., all show its extraordinary, but these are obviously far from the real core secrets of this cave, and Zhou Feng vaguely feels that the real secret is probably still in this dark cave.

And Zhou Feng has not yet found a way to leave this cave, instead of closing his eyes and waiting for death, it is better to fight, maybe there is a glimmer of life!

Walking cautiously towards the swarthy cave entrance, as soon as I saw it, I could feel a cold chill coming out of the hole, and it felt a bit like the biting chill experienced on the way to refining my heart.

Slightly turned the cold ice internal qi to let the body get used to it for a while.

Zhou Feng didn't hesitate, and as soon as he buried his head, he got into the hole and disappeared into the darkness.

Click~~~

After a mechanical sound, the stone table above his head was closed again, and Zhou Feng suddenly fell into a boundless darkness, and it was pitch black as far as his eyes could see, even if his cultivation of the tenth order of internal qi and his five senses were increased several times, it was useless.

Stretched out his feet and nodded his feet, solid, there are steps!

Zhou Feng slowly groped his way down the steps one by one.

This stone step is quite long, and it slowly winds down with a certain arc, Zhou Feng has walked for a long, long time, and he must not have felt like stepping on the ground.

Fortunately, Zhou Feng has already had an encounter like refining his heart, guessing that this is mostly a test, people are prone to certain emotions such as weakness, irritability, and throbbing when they are in the dark, and being in this environment for a long time is even more likely to make people's spirits collapse.

On the contrary, if you can adapt to such darkness and restrain and guide these emotions, then it is also a very good way to exercise mental power.

This is what Lan Lao once mentioned in passing when he taught Zhou Feng about spiritual power, and when Zhou Feng walked in such an environment for about half an hour, these words of Lan Lao appeared in Zhou Feng's head.

If you don't know anything, it may be easy for a person to collapse, but when Zhou Feng is prepared, he naturally doesn't take it to heart, but slowly groped forward and continued to walk, while thinking about some difficult problems in cultivation, and even danced his hands twice from time to time to confirm whether he had considered it thoroughly, etc.

Adversity~~~

But just when Zhou Feng was a little slack, he stepped on the foot and suddenly stepped into the air, and his body suddenly fell uncontrollably.

Zhou Feng suddenly twisted his body, trying to flip his body that had shifted his center of gravity down onto the steps again.

But......

The stairs are gone!

The steps that he had walked down before instantly turned into nothingness, and disappeared without a trace, Zhou Feng stepped on it even more, and his body was even taller and retreated sharply, but he still didn't touch anything.

Without the support of the physical object, Zhou Feng had nothing to focus on, and could only feel his body constantly falling downward and falling......
