Qin Yang calculated, if the mountain gate was opened, it would take more than three years to accumulate aura. If you borrow the spontaneously generated aura from the second layer, it may be about the same in less than two years.

But the question is, do you pat your ass and walk away after opening the door? Leave a door open for others to enter and exit?

Although there are bodyless demon soldiers guarding the door, any Emperor Realm powerhouse can enter freely, even a Saint King-level powerhouse can enter. Once outsiders enter freely, something may go wrong.

The most terrifying thing is, where is the bastard of the Demon Emperor? That guy is floating in the sky all day long, almost everywhere, will he be eyeing the Ten Thousand Demon Cave with the mountain gate wide open? If the Demon Emperor invades and occupies the Ten Thousand Demon Cave, and one person controls the two ancient holy lands, the fun will really be great.

Moreover, although the Demon Emperor's current strength is not very strong, if you want to talk about the ancient secret method, you must know a lot. Even if he can't control the Ten Thousand Demon Cave, he will definitely mess up Qin Yang's control.

Therefore, you have to close the mountain gate after leaving. But if you turn it off, you need to consume the same aura again. That's about four years to be in it!

I miscalculated, I miscalculated, I'll it...... Qin Yang was a little big.

Four years have become more and more difficult.

Of course, if Qin Yang decided not to take control of this Ten Thousand Demon Cave, and let outsiders come to snatch it, he should be able to get out in two years. But, is this possible? How great is it to be able to control the primeval holy land in your own hands?

You must know that the Ten Thousand Demon Cave and the Demon Emperor's Starry Sky City are the same name, and they are big treasures!

And if it is obtained by the Demon Emperor, will it have unpredictable and terrible consequences?

Qin Yang looked at this deep wellhead a little tangled, and helplessly tried to pull the heavy throne back and cover this wellhead.

At this time, he was about to return to the second floor, and of course he accidentally looked at the mutilated body of the holy ape. Forget it, there's no place to place it anyway, it's the same everywhere you throw it, just stay here. But seeing the hand of the holy ape lying on the ground, Qin Yang's eyelids jumped.

Warn...... Finger!

This guy is wearing a ring, and it looks very special!

Moreover, the demon clan has never refined such a thing, could it be that it was obtained in this ten thousand demon caves? Moreover, even if it is an ancient demon clan, it is estimated that there are enough to choke a few people who can refine high-grade treasure weapons, maybe the ancient demon clan forced the human refiner to refine it.

Qin Yang immediately ran over and took off the ring. This ring is not very large, so the big hand of the Holy Ape can only be worn on the little finger, and it can't even be worn to the base of the finger. And Qin Yang wears it on his finger, which is just right.

Well, there's one more, and that's pretty fancy.

Then, Qin Yang input his soul power into it, trying to see if he could react. As a result, it didn't matter if I tried it like this, and I was stunned -

Star Ring!

And it is a complete top-level star ring, a real star ring, and it is definitely not this kind of residue refined by Zhou Xinghe. This kind of star ring, which the current refiner can no longer refine, should be similar to the palace master ring on Zhou Heling's hand!

Because it is a top-notch star ring, after the previous owner erases his own characteristics or dies, it will automatically become an ownerless ring, which can be used by future generations. It's as if Zhou Xinghe gave the palace master ring to Zhou Heling, and it has been passed down from generation to generation.

Now that the holy ape is injured and dead, this ring has become ownerless, and Qin Yang will be able to open it.

And the scene after opening, Qin Yang didn't know how to describe it - a spherical space with a diameter of about one zhang, one zhang, like a house!

Qin Yang's broken star ring only had a square space about five feet in diameter, and the gap between the things that could accommodate it was too big and too big.

And this spherical space was empty, and only three jade bottles were placed in one corner of the space. Each bottle is the size of a child's fist, crystal clear and cute to look at.

Qin Yang took out the three bottles one by one and found that two of them were empty, and only one seemed to contain some liquid. Since the bottle is a bit translucent, you can see that it contains about a third of the thick liquid.

Somewhat familiar, this liquid looks familiar.

Qin Yang carefully unplugged the stopper on the bottle, and that familiar breath came to his face. This guy resisted the urge of his heart to beat violently, and immediately plugged it, bursting with joy - leyline refining liquid!

I'll it, how much is this?

You must know that the thumb-sized jade bottle of Emperor Rouran at the beginning could store a hundred drops of earth vein refining liquid. It's just that when Qin Yang got it, Emperor Rouran had already used a lot, so there were only a few dozen drops left.

Such a small bottle can hold a hundred drops. And the bottle in front of me is the size of a child's fist, I'm afraid it can hold a thousand drops, right?

Therefore, even if this bottle of leyline quenching liquid is only one-third, there are at least three hundred drops or more!

More than three hundred drops, if the first layer of the Ten Thousand Demon Cave is running at full capacity, it will be enough to use it for four or five months. If you use it sparingly, it doesn't matter if you use it for a year.

It's a pity that this has to be used in conjunction with the star marrow. Only by putting the two into it at the same time can it produce the kind of aura that the Ten Thousand Demon Caves need.

Therefore, even if the Holy Ape Wound had these leyline refining liquids, even if he knew the demand and effect of the aura, he could only sadly say that he would not be able to open the mountain gate after three years. There is no way, he only has this one resource in his hands, but he has no star essence.

And now, Qin Yang still has the star essence in his hands!

At the beginning, I got a lot from the Kunyuan World and the Void of the Universe, and after I came back, I handed over a hundred catties to Uncle Su, and I spent some when I continued the Starry Sky Ancient Road, but now there is still no less than 150 catties of stock.

It stands to reason that every time the mountain gate is opened or closed, it takes thousands of catties of star marrow. If Qin Yang's 150 catties are put in, of course, it will not be enough, but at least it can save a lot of time.

Moreover, Qin Yang further thought: Where did this ring come from? The Holy Ape Wound must not have it, so it should have been obtained from the Ten Thousand Demon Palace. Perhaps, this ring was used to collect and store the star essence and leyline quenching liquid for the Ten Thousand Demon Caves ten thousand years ago. At this point, the more than three hundred drops of leyline refining liquid stored in the ring are a strong evidence.

So, there is such a ring in the first floor, but what about the second floor? Does the second floor also need this kind of inventory? If there is, then it should be in the Demon Emperor Palace, or even near the throne. After all, the deep well beneath the throne is where these supplies are filled.

Previously, Qin Yang really hadn't searched carefully there, but simply pushed the throne away and looked at it once. Now we must go back and do a good search.

If...... It would be nice to find some star essence, I hope so.
