Although he had the intention to enter the underworld, Bai Ye would not come up and enter by himself, but would first try and probe with a puppet to ensure that it was safe before entering.

And this time, entering the underworld with a puppet and taking the dark water of the black pool is the first temptation.

At that moment, Bai Ye took out a puppet heart from the storage bag, and only opened a trick, and the prohibitions on it belonged to the exploration category, which were all refined when he was researching the five kinds of puppet heart prohibitions. I haven't used it all the time in a storage bag, and now it can come in handy.

He also took out some materials for refining the puppet body, such as pure gold and silver refining, and began to refine the puppet body.

Hesitation This is just a temptation, just passing through the yin and yang channel and going to the opposite underworld to get a piece of black water.

Therefore, Bai Ye did not refine it very finely, not even in human form, but a small round ball, which could be suspended in the air, and a jade bottle was placed in it for the black water of the secluded pool.

After placing the puppet heart in it, after thinking about it, he split another thought and merged it into the puppet's heart.

"The first exploration of the underworld, let's call you 'Explorer One'!"

Casually giving the ball puppet a name, Bai Ye activated the 'Explorer One' puppet, brought it to the entrance of the cave, and threw it directly into the yin and yang spring below.

'Explorer 1' immediately sank to the bottom, the puppet heart ban was activated, a round mouth was cracked on the ball, and a light wave shot out, probing the surroundings and determining the location of the spring's 'yin and yang channel'.

Then, Explorer 1 rolled past the bottom of the spring, submerged into the spring, and entered the spatial passage.

Bai Ye immediately urged the 'Kunlun Mirror' spirit ban and observed the situation in the 'Yin and Yang Channel'.

I saw the puppet of 'Explorer No. 1', constantly advancing in the twists and turns of the 'Yin and Yang Passage', slowly heading towards the underworld.

At the same time, in the cracked round mouth, various lights, sound waves, and spiritual light are constantly emitted, which are the settings added by the white night to detect and explore various situations in the 'yin and yang channel'.

In order to collect information and accumulate experience for more explorations in the future, real body entry, etc.

'Explorer 1' continued to move forward without any accidents in the early stages.

However, when the puppet advanced to the middle of the 'Yin and Yang Passage', which should be the boundary between the Yin and Yang worlds, it suddenly stopped, as if something was blocking it in front of it, and 'Explorer 1' could not continue to move forward!

Bai Ye frowned slightly, and immediately urged the thought that melted into the puppet's heart, instantly controlled the puppet, and urged the 'Explorer One', the cracked round mouth forward, all kinds of light, sound waves, and spiritual light, scanning and probing forward.

Gradually, the obstacle ahead became clear in Bai Ye's mind, and he judged that it should be a spatial barrier!

Maybe it was because the distance was too far, or maybe it was because Bai Ye's power was not enough, and when he urged the 'Kunlun Mirror' spirit forbidden, he didn't see this spatial barrier.

This spatial barrier should be the boundary between the two worlds of yin and yang.

"It's just that how did those skeletons pass through the spatial barrier and come to this secret realm from the underworld?" Bai Ye suddenly remembered the skeletons that were raging in this secret realm before, and couldn't help but be a little puzzled.

It's a pity that after he found that there were skeletons entering the spatial passage, he immediately shook the spatial passage and killed all those skeletons.

I couldn't see how the skeleton passed through the spatial barrier at the boundary between yin and yang!

Could it be that under the Yin and Yang Tribulation, the spatial barrier of the boundary between Yin and Yang is only aimed at the Yang World, not the Hades?

Bai Ye's thoughts flipped over, and he couldn't find any reason, so he could only put it down first.

What he needs to solve now is how to get the puppet to pass through that spatial barrier and enter the underworld to explore!

"If a puppet wants to enter the underworld, it will undoubtedly have to tear through that spatial barrier...... And if you want to tear through the space barrier, the puppet must master the power of space!" Bai Ye turned around in his heart a few times, and gradually had some ideas, "To let the puppet master the power of space, there are two ways, the first is that I refine a 'Kunlun Mirror' magic weapon and install it on the puppet!"

"The second way, maybe I can add the legal ban of the 'Kunlun Mirror' to the puppet heart ban?"

Of the two approaches, the first is undoubtedly simpler and more feasible.

But the second method kept coming to Bai Ye's mind, making it difficult for him to let go!

The master said that the real puppet master can design the puppet heart ban by himself. On top of the most basic puppet heart prohibitions, add various prohibitions so that the puppets have all the abilities they want!

At the beginning, the master asked him to study the five types of puppet heart prohibitions, find out the commonalities, and find out the most basic puppet heart bans, isn't the purpose to design the puppet heart ban by himself later?

The light in Bai Ye's eyes became brighter and brighter, and he gradually made a decision in his heart, and he decided to try the second method first. Design a set of puppet heart bans by yourself, and add the 'Kunlun Mirror' legal ban to the 'puppet heart' ban!

If you really fail in the end, choose the first method and add a 'Kunlun Mirror' magic mirror to the puppet.

This is the pursuit of a puppeteer.

With a decision in mind, Bai Ye immediately summoned back 'Explorer One'.

Soon after, the ball puppet emerged from the Yin-Yang Spring, flew out of the hole in the ground, and landed on the ground.

The puppet of 'Explorer One' has declared a failure in its first exploration of the underworld!

Bai Ye didn't care, took out the puppet heart, collected the idea of integrating into it, and took out the 'Yin and Yang Channel' collected inside, as well as the information and materials that were blocked by the space at the boundary between Yin and Yang, and stored them for special storage.

These are all important research materials for the continued exploration of the underworld and the improvement of the puppet after the White Night.

Then, he began to play with the puppet heart, researching how to add the 'Kunlun Mirror' legal ban to it.

The first thing that comes to mind must be to directly brand the 'Kunlun Mirror' legal ban on the puppet's heart.

Bai Ye knows that this will definitely not work, but if you don't try it, you won't know where the conflict is, where the mistake is, and you won't know where to start, to study and improve!

So, he took a puppet heart in his hand, and entered his mana and spiritual sense into it at the same time, and began to brand the 'Kunlun Mirror' forbidden.

This is the imprinting forbidden, you can use mana and spiritual sense to imprint, and if you want to brand the spiritual forbidden, you must use the power of the soul.

One legal prohibition, two legal prohibitions, and three legal prohibitions...... It has been imprinted until the fourth 'Kunlun Mirror' legal ban, and finally this legal ban inevitably has a handover, overlap, and collision with the original prohibition in the puppet's heart.

There was another click, and the original prohibition on the puppet's heart was directly broken, and this puppet's heart was directly cracked and damaged.

"Three 'Kunlun Mirror' Law Bans?" Bai Ye frowned and shook his head, there are only three 'Kunlun Mirror' Law Bans, which can disturb a little bit of space ripples at most, and it is impossible to tear the space apart.

With Bai Ye's experience in using the 'Kunlun Mirror' forbidden during the Qi refining period, if you want to have the power to tear through the space, you need at least eight 'Kunlun Mirror' forbidden laws.

After thinking about it, Bai Ye didn't take out the 'puppet heart' that had been refined, but took out a piece of spirit wood.

He wanted to start by branding the 'puppet heart' ban, and try to integrate the 'Kunlun Mirror' magic mirror into it.

The first imprinted 'puppet heart' prohibition is the incomplete 'basic puppet heart prohibition' that he summed up from the five types of puppet heart prohibitions.

Although it is broken, this set of prohibitions is the foundation of the puppet heart, and it is a must!

Then, he began to add prohibitions to this set of broken 'puppet hearts' basic prohibitions.

Explore the prohibition of puppet-like hearts and the legal prohibition of 'Kunlun Mirror', two sets of prohibitions, each in one, but both are connected to the most basic 'puppet heart' prohibition.

A little bit more, one by one the law ban brand, Bai Ye focused, the thoughts in his heart were very active, he only felt that his mind was extremely clear, his mind was extremely transparent, every puppet heart prohibition, every 'Kunlun Mirror' law ban, he successfully found the best imprint.

When the last 'Kunlun Mirror' forbidden law was successfully imprinted on the puppet's heart, Bai Ye let out a sigh of relief, holding the 'Stone Heart' that had just been successfully refined, and he only felt extremely happy in his heart!

Nine Kunlun Mirror Law Ban, he has successfully added it to this exploration class 'puppet heart' ban!

He didn't expect it to be so smooth, and he would succeed at one time, if God helped! It was as if the connection and fusion of these prohibitions had already been in his heart, just waiting for him to imprint them out at this time!

Or, it's also a thick accumulation!

The prohibition of the 'puppet heart' and the prohibition of the 'Kunlun Mirror' have long been familiar to him. He has spent four years studying the integration of the 'Yin-Yang Mirror' and the 'Kunlun Mirror' legal ban, and he has long been experienced.

Now, the 'Kunlun Mirror' legal ban is integrated into the 'puppet heart' ban, but it is extremely smooth.

The ban brand is successful, and the next step is to get the hang of it.

Bai Ye looked at the 'Stone Heart' in his hand, measured the distribution of the seven stars, and successfully found the location of the 'Shaking Star'.

The mind sensed the 'Shaking Light Star' in the sky, and the corresponding rune was thought of in the Zhihai Dantian, and the starlight flashed on Bai Ye's fingers, and he successfully opened a trick on the newly refined puppet heart.

Another success, and White Night feels that today's state is surprisingly good!

At the moment, without delay, he picked up the round puppet body of 'Explorer 1' and made some changes.

The puppet heart has been improved and integrated into the 'Kunlun Mirror' legal ban, so this puppet body naturally needs to be improved.

Half an hour later, everything was ready, and Bai Ye put the puppet heart that had fused with the 'Kunlun Mirror' legal prohibition into the improved puppet body.

The improved puppet shell is still spherical.

White Night casually named it: "Explorer II".

Explorer 2 activates and throws itself into the Yin Yang Fountain again.

The puppet successfully found the spring and entered the 'Yin and Yang Passage'.

The first half of the journey was still very smooth, and the 'Explorer 2' soon arrived at the boundary between yin and yang, the place where space is blocked.

Now, it's time to test the success of this puppet improvement!

Bai Ye directly controlled the puppet with the idea of integrating into the puppet's heart, and personally urged the 'Kunlun Mirror' legal ban.

The next moment, from the cracked round mouth on 'Explorer 2', an invisible space-tearing force shot out, crashing into the space barrier in front of it.

In just a few moments, the 'spatial barrier' was torn out of a crack, and Bai Ye immediately urged the 'Explorer II' to break through the crack!

"It's a success!" Bai Ye's heart was overjoyed!
