'Explorer 2' successfully passed through the spatial barrier at the boundary between yin and yang, and entered the spatial passage on the side of the underworld.

White Night was very happy. However, after only a moment, his brow couldn't help but furrow slightly.

He found that the spatial passage of the underworld was filled with a rich yin qi, and these yin qi was slowly eroding the 'Explorer II' puppet!

It's slow, but you can feel it!

I'm afraid this 'Explorer II' will not be able to survive in the underworld for long!

Frowning slightly, Bai Ye continued to urge the puppet forward, walking in the rich yin qi.

From the cracked round mouth, various sound waves, rays, and spiritual lights continue to be shot, detecting and probing the situation on this side of the underworld in the spatial passage.

Then all the information and information obtained are stored in the puppet's heart.

This is the role of the exploratory puppet, the puppet heart forbidden.

In the winding spatial passage, the puppet moved forward at a uniform speed, probing the surroundings, and after most of the day, it finally reached the end of the passage and entered the underworld.

On the top of the black mountain, in the black water of the secluded pool, a silver ball suddenly appeared, sinking and floating in the black water.

There was a snorting sound, and the black water quickly eroded the ball, and green smoke rose, and the silver surface on the ball quickly became pitted, and even began to crack and fall off.

This black water in the underworld is unexpectedly strong in terms of erosion and corrosiveness!

In the heart of the 'Explorer 2' puppet, the idea of white night differentiation immediately controlled the puppet and changed the puppet's preset detection mission.

Originally, the mission of 'Explorer 2' was set up by White Night to fly out of this secluded pool and explore near the black mountain in the underworld.

It's best to also collect some things from the underworld, such as netherworld, skeletons, ghost fire, and the like.

But now looking at the corrosion speed of this black water, Bai Ye immediately canceled all these tasks, and took the black water of the hidden pool as the first priority!

The ball puppet in the black water, which was constantly corroded and eroded, opened a crack, stretched out a round pipe, and began to suck up the black water of the dark pool.

In just a moment, the black pipe that stretched out was damaged by the black water.

The surface shell of Explorer 2 has also been corroded and peeled off!

White Night did not delay any longer, and immediately drove the puppet back.

A potholed puppet with a peeling surface. Quickly sink to the bottom of the pool and enter the yin and yang channel.

Along the winding passage, 'Explorer 2' staggered forward, and the erosion of the black water in the dark pool had corroded and destroyed the puppet's shell, and even began to erode the golem's interior.

The heavily protected puppet heart in the center is still intact and has not been eroded, so it is still able to control Explorer 2 to move forward.

However, this progress has inevitably been affected and slowed down.

At the same time, it is also slowly being eroded by the rich yin qi in the channel.

Bai Ye was a little worried about whether 'Explorer II' would be able to hold on to coming back.

Fortunately, although the speed was slow, the puppet finally reached the boundary between yin and yang again.

The space barrier ahead is once again blocking the way!

The White Night Control Puppet tried, but found that it could not directly pass through the spatial barrier.

It shows that his previous guess was wrong, and the spatial barrier at the boundary between yin and yang is aimed at both sides of yin and yang.

As for how those skeletons crossed the spatial barrier, it was an unsolved mystery.

Maybe there's something special about it?

Bai Ye controlled the puppet and urged the 'Kunlun Mirror' legal ban, and the invisible power of space tore the space barrier again.

Explorer 2 passed through the spatial rift and entered the yang side of the spatial passage.

Without the erosion of the rich yin qi, Bai Ye finally came to his heart.

'Explorer 2' advanced slowly, and after more than half a day, it finally came out of the passage and flew out of the Yin Yang Spring.

Bai Ye immediately caught the puppet and inspected it, and found that the puppet's body was nearly half damaged, and all kinds of exploration devices installed inside had been damaged.

The puppet heart is still intact, there is no damage, and all kinds of information and information recorded in it are intact.

There is also a jade bottle containing black water, which has been specially refined and has not been eroded by black water.

Bai Ye looked at the jade bottle in his hand, and his face was thoughtful.

This jade bottle is made from the waste jade left over after the spiritual jade used by the foundation building monks for cultivation has exhausted the spiritual energy, and it has been specially refined.

"Could it be that the puppets who explore the underworld in the future will not be able to refine with these waste spirit jades?"

Bai Ye shook his head, this was a bit unrealistic, even if it was a spirit jade without aura, it was impossible for him to obtain a large amount.

"It seems that we have to find some materials that can withstand black water and yin qi, and refine special puppets to explore the underworld!"

"So where is such material?"

Bai Ye pondered for a moment, and suddenly thought of the Qiyun Ghost Town mentioned by Senior Sister Xie Jing!

There are ghosts and things rampant, and the yin qi is pervasive, and it is inevitable that many of my abnormal materials can withstand the erosion of yin qi.

"It seems that the trip to the ghost town in half a year will also pay attention to collecting some materials for refining puppets!"

Bai Ye decided in his heart, and opened the jade bottle again to check the black water in it.

Sure enough, there was a terrifying cold, yin, and dead air rushing in.

The natal spirit weapon in the white night sea dantian was immediately shocked, and the side of the yang mirror lit up, and the white golden light came out of the body, protecting the white night.

Bai Ye looked at the black water in the jade bottle, felt the cold and dead silence in it, and nodded with satisfaction.

Such a terrifying cold and dead air is just opposite to the true fire of the sun!

Next, as long as he separates another ball of Sun True Fire, he can practice the spiritual techniques of 'Xuanyin Water Method' and 'Xuanyang Fire Method'.

There is also the spiritual technique 'Thunder Urn', as well as several spatial spiritual techniques recorded in the 'Cave Xuan True Scripture', which are about to start cultivating.

In preparation for a trip to a ghost town in half a year.

"Huh?" Just as Bai Ye was about to put away the lid of the jade bottle, he suddenly sensed that something seemed to be beating in his storage bag!

His spiritual sense reached into the storage bag and searched for it, and finally locked on a jade box.

The jade box contained the black lotus seeds he had intercepted from the Heavenly Ghost Sect!

Or according to the Ghost Sect Jindan Female Cultivator that day, that lotus seed is called 'Netherworld Lotus Seed'!

Bai Ye thought about it, unsealed the jade box, and took out the 'Netherworld Lotus Seed' in it.

I found that the lotus seed was agitated more and more, and I almost jumped.

The spiritual consciousness of the white night lingered around the black lotus seed, vaguely catching some thoughts and information.

'thirst', 'water', 'thirst', 'water'......

He couldn't help but be stunned and looked at the lotus seeds in the jade box.

This lotus seed is actually conscious? Calling 'thirsty' and 'water' is asking me to water it?

He couldn't help but look at the black water in the jade bottle, the lotus seed didn't have these reactions before, and it wasn't until he obtained the 'black water' in this jade bottle that he had such a violent reaction, obviously he was going to use this black water to water it!

After thinking about it, he poured the jade bottle, and the black water dripped onto the black lotus seeds. was quickly absorbed by the lotus seeds, and the black lotus seeds instantly bloomed with brilliant black light, and quickly agitated.

Seeing this, Bai Ye immediately removed the jade bottle and cut off the black water for watering.

The black light gradually faded, and the lotus seeds vigorously agitated, and the thoughts of shouting 'thirst' and 'water' suddenly became stronger!

Bai Ye shook his head, re-sealed the jade box, and put it in the storage bag.

Obviously, this Netherworld Lotus Seed is a living creature, and it can be planted and grown in the black water of the dark pool of the underworld. As for what will grow in the end, not necessarily!

He can't control this lotus seed yet, so naturally he can't let it absorb the black water and grow, otherwise who knows what will come out in the end.

Put away the black water of the jade bottle, and dispose of the 'Explorer 2', which was nearly half destroyed by erosion, and put it away.

At this point, the first exploration of the underworld is over.

The first goal is to get the black water in the secluded pool.

A further goal, to explore the situation of the underworld around the hidden pool, but failed.

Overall, the exploration was a success.

In the time that followed, Bai Ye did not explore the underworld again, but began to cultivate spiritual magic with all his might.

The Xuanyin Water Method, the Xuanyang Fire Method, with the dark water of the hidden pool and the true fire of the sun, the cultivation is very smooth.

Thunder is a kind of thunder magic. The so-called '箓' is a book of heaven-given talismans, which can lead to the power of heaven and earth, and lead the power of heaven and earth down!

Cultivating the 'Thunder Urn' Spiritual Technique, the White Night uses the 'Yin and Yang Thunder Method' to form the 'Thunder Jar', which can lead to the power of heaven and earth to bombard down, and the power increases sharply!

Moreover, the 'thunder basket' can be formed in the Zhihai dantian first, and when needed, it can be directly excited, and there is no need to make thunder marks, turn thunder methods, and delay time.

Time passed slowly in the process of practicing all kinds of spiritual arts in the white night.

Three months later, the kitten demon built the foundation, and the white night protected it.

It took 100 days to successfully complete the foundation building.

When the kitten demon came out, Bai Ye noticed at first glance that behind the kitten demon, one tail had become two.

"Meow ......" saw Bai Ye staring at its two tails, the kitten demon seemed to be a little embarrassed, and the tail flickered, and the two became one again.

"White ...... White Night ......" Suddenly a crisp voice sounded, it was the little cat demon who spoke.

After the demon builds the foundation, he can refine the horizontal bones and speak human words.

"Seven snows!" Bai Ye called tentatively.

"White Night!" The little cat demon seemed to be familiar with speaking human words, and spoke more and more smoothly, "White Night, I have finished building the foundation and am going back to the mountain to find my grandmother." ”

"Learning the Heavenly Machine Technique with my grandmother, I estimate that I will have to practice in retreat in the sect for a period of time!"

"So, you can't go to the ghost town with me?" asked Hakuya.

The kitten demon retreated and practiced for three months to build the foundation, and it was another three months to build the foundation for 100 days, and at this time it was already half a year, and it was about to come to the day of departure to the ghost town agreed with Xie Jing.

The little cat demon nodded and said, "My grandmother and I are afraid it will take at least half a year to learn the Heavenly Machine Technique." ”

"It's best if you can postpone your visit to the ghost town for another half a year!"

Bai Ye frowned slightly, shook his head and said, "Forget it, I have already made an appointment with Senior Sister Xie, so it's not good to postpone it temporarily." ”

"Then without me by your side, you have to be careful in the white night...... "The kitten demon said with some concern.

Bai Ye smiled and nodded: "Qixue, don't worry, I am full of life-saving things all over my body now, and the last thing I have to worry about is safety!"

He had already told Qixue about the Yin and Yang Tribulation, the establishment of reincarnation, and the various treasures given in the door.
