In this blue sky and white clouds, such a black ancient tower looks very abrupt and strange.

Wu Yu was now in front of this black ancient pagoda.

At this time, he was looking for a safe place, and the appearance of this black ancient pagoda undoubtedly attracted his attention and attention.

However, in fact, he also understood that judging from the prominence of this black ancient tower here, it was more likely that this place would make him more conspicuous and easier to find.

He circled around the black ancient tower, and when he looked closely, he found that the style of this ancient tower was very simple, and the appearance was pitch black, as if there were no magic circles and patterns.

However, you don't have to think about it to know that there must be a lot of mystery in this interior, and even, maybe all the mysteries of the entire blue sky and white clouds are in this black ancient tower.

"No matter how many of these towers there are, you should be lucky to see one now. Others may not be able to meet it. "Stykashi.

Her words made Wu Yu feel reassured.

At the bottom of the black tower, he found a door, and it was pitch black, and he couldn't see anything.

But obviously, the mysteries of this whole world may be inside this dark door.

"Can't get in?"

For Wu Yu, this is a relatively important decision.

"If you don't go in, you might miss out on some opportunities. It is also necessary to continue to find a place to hide, not to mention whether there is a safe place to live. Even if I leave for a while, I guess other people will find it too. ”

"If you go in, it's a gamble. However, I've been gambling until now, am I afraid of gambling?"

Thinking of this, Wu Yu smiled.

Indeed, he could see something at all now, and he went there.

Before entering, he still studied the black ancient pagoda and made some preparations.

The part of this black ancient tower under the clouds, Wu Yu had already seen clearly, there was nothing. On the other hand, the part above the clouds, the position of the spire, is not the traditional sharp spire, the top of the ancient tower is flat, there is a small platform, and above the platform, there is an ancient, stone sundial.

Wu Yu was certainly familiar with the sundial, which was a timekeeping instrument used by mortals to keep track of time, and the sundial was usually composed of copper hands and stone discs. The hands are called sundial needles, which pass vertically through the center of the disc and act as a neutral rod in the table, and the stone disc is called the "sundial face" and is placed on the stone platform.

There are scales on both sides of the sundial, and there are 12 hours of molecule, ugly, yin, mao, chen, si, noon, wei, shen, unitary, xu, and hai, and each hour is divided into "the beginning of the time" and "the time is positive".

Through the sundial, mortals know the time of any moment of the day.

Styx said that this sea of clouds is a change in time, and on the top of this black ancient tower, there is a sundial that records time, which undoubtedly shows that this tower may have something to do with time!

"Look, what's so peculiar about the shadow of the sundial needle?"

Mortals record the passage of time through the change of this shadow on the scale.

Wu Yu has those fiery eyes, and he can actually see the subtle changes in this shadow.

Since he said it, he looked at it carefully.

"You mean, this shadow has nothing to do with the sun in the sky?"

The position of the sun in the sky has not moved, in the middle of the sky, but there is a long shadow on the sundial, and it is obvious that this shadow has nothing to do with the sun in the sky.

"That's one of them. ”

Wu Yu looked at it again, but he didn't understand it.

In the end, Styx said proudly: "Stupid, the change in the time of this sundial is twice as long as the normal time. ”

Wu Yu was taken aback, he went to pay attention to the very subtle changes in the shadow, and sure enough, it was twice the speed he expected!

In fact, the shadow became very slow, but Wu Yu could see the slightest change.

"What does this mean?" Wu Yu asked.

Stytaki rolled his eyes and said, "Who knows, didn't you decide to go in, go in and see." ”

Wu Yu didn't dare to stay on this sundial for too long, it was estimated that it wouldn't be long before everyone knew that he had snatched the ancient crystal of the Yanhuang Ancient Kingdom, and they all knew that he had a heavy treasure in his hand, that is, a rat crossing the street, and everyone shouted and beat him.

Until then, he has to have some changes and means to protect himself.

Perhaps, in the midst of this ancient black tower.

Thinking of this, Wu Yu directly pinched the ancient immortal talisman and landed in front of the door of the black ancient tower, without saying a word, he stubbornly walked into the gate of the black tower.

The moment I stepped through the door, the originally dark world suddenly lit up.

The Black Tower is not big, and the door is not big, but what is surprising is that there is a fairly large area inside the door.

The space in front of him was circular on the ground, and the diameter was estimated to be about hundreds of miles, although it was also a sight to see the end, and the surrounding walls could be seen, but such a huge space was enough for several people to fight here and play to their heart's content.

In fact, looking at the diameter of this black tower from the outside, the thickest part is only half a mile, which is definitely not so big.

"I don't know the time, but the space has changed, and it is estimated that this space is the same as the Nazi array diagram of the bag of Sumeru. ”

As soon as Wu Yu came in, he quickly took in the surrounding environment.

The ground is flat and pitch black, carved with many strange lines, and there is no change or movement for the time being, I don't know if it is a magic circle.

The same is true of the surrounding walls, with many pitch-black, ripple patterns like water waves, wave after wave, temporarily dim, with Wu Yu's level, it is still impossible to see whether this is a magic circle.

However, the sky is very strange, because when you look up, you can see the blue sky and white clouds, and you can see the scorching sun at that moment overhead.

As if the top of the tower did not exist.

The sun's rays burned on the body, and there was a burning sensation that did not exist outside.

"That's it in there, nothing?"

Wu Yu just thought about this, when there was a sudden change behind him, I don't know when, the gate he came in had disappeared without a trace.

He's stuck here.

Although there is the sky above your head, you don't have to think about it to know that it is not a place where you can go out, and the reason why you can see the sky may also be a change in the magic circle.

He clenched the Ancient Immortal Talisman and looked around vigilantly.

Blacktower didn't let him wait long either.

Just after the door behind him disappeared, on the opposite wall, the carvings on the wall began to change, and finally converged into a vague human face, which said indifferently and mechanically: "Ninety-three 'Time Ancient Tower'." Change time, twice as much. Conditions: Defeat the guards and stay for 10 days. After 10 days, if someone challenges, if they win, they will stay for another 10 days, and if they lose, they will be replaced. If there is no one to challenge, you will need to fight again. ”

The face and voice of this person were obviously set up a long time ago, and they sounded very old, and their speech was very boring.

However, this information is important to Wu Yu!

"Ninety-three Time Pagoda, meaning that the change time is doubled, and there are still conditions?"

Obviously, the name of this place is the Ancient Tower of Time.

Who took the name and who built it, nothing is known.

But Wu Yu's personal experience, coupled with the change of the sundial before, he guessed that the speed of time flow here should be twice as fast as outside! That is to say, ten days have passed outside, and twenty days may have passed here.

I just don't know if this face can stay for ten days, whether it is ten days outside or ten days inside.

"Conditions?Defeat the guards?Where are the guards?" Stytaki also looked around curiously, as if there were no guards.

Wu Yu was pondering what the face said, and at this time, the face had disappeared.

"It's like an abandoned place, but the circles are still in operation, and the Ancient Tower of Time is also in operation. I'm supposed to be the first person to enter this Tower of Time in a long time, so I have to defeat the guards to stay for ten days. ”

"It means that after ten days, the door that was closed just now will be opened, and then if someone comes to challenge, then the winner will be divided, and if I win, I can stay for another ten days, and if I lose, I will be replaced and stay here. If there is no one to challenge, I will still have to fight the guards, once every ten days!"

The other party said it relatively simply, and Wu Yu understood it.

"If you can stay in this ancient tower of time all the time, it is indeed very rebellious, because at least this way, the lifespan will not increase, but in the same period of time, it still has twice the time advantage over others. For example, if I cultivate for ten years, others will cultivate for ten years!"

It's a pity that it's not easy to stay in this time, not only will others come to challenge, but also challenge the guards every ten days!

What is the strength of the guard, Wu Yu doesn't know for the time being.

However, he knew that he would soon find out, because the guards would definitely appear.

Sure enough, at this moment, the ground lit up, and in the center of it appeared, a magic circle with a diameter of about ten zhang appeared, the magic circle was complex and shining, and in this light, a figure gradually appeared from it, and finally the magic circle disappeared, and a figure with a height of one zhang appeared in front of Wu Yu's eyes.

However, this is not a human, but a silver-colored steel golem, and every part of its body, its head, torso, hands, and legs, is made of precious metal materials, which are obviously Chaos Treasure-level materials.

On his body, if he doesn't look carefully, it seems that there is no magic circle, in fact, the magic circle is all hidden in the body, and there are tens of thousands of magic circles in that body, there is no doubt that this is the most powerful puppet Wu Yu has ever seen.

The magic circle on it was also something that Wu Yu had never seen before.

The strongest person he had ever seen in the Organ Circle was the Xuanji Sword Saint, but the Xuanji Sword Saint obviously didn't have the legal system to make the ancient, cold silver puppet in front of him.

At this moment, the silver puppet opened its eyes, and its tens of thousands of magic circles were operating at the same time, like a flood beast, staring at Wu Yu.

"It's so strong!"

Wu Yu realized that this was a difficult challenge......

However, he had already come in, and he didn't want to slip out like this, at least in this interior, he had ten days, or twenty days, to safely exercise the 'Dragon Venerable King Buddha is not bad'.
