Looking at the little cat demon's sad face, Bai Ye couldn't think about it, he didn't know anything about the cultivation of the Heavenly Machine Technique, so he could only comfort: "Since my mother-in-law said that when the time comes, she will naturally understand, you don't have to worry, practice slowly, eat, drink and have fun, I will accompany you until the time comes!"

The sorrow of the little cat demon came and went quickly, and when he heard Bai Ye's comfort, he suddenly turned to joy, and screamed softly: "Meow! Bai Ye, you are right, whenever the time comes, eat, drink and have fun...... In order to celebrate your success, we will have a big meal at the last seafood feast again, and we will have a big meal and celebrate!"

When Bai Ye heard this, he immediately cried and laughed: "Qixue, is this my success in marrying Dan, or is it your success in marrying Dan, how do you feel like celebrating you?"

The little cat demon raised his head and said: "We are contract partners, don't you celebrate as I celebrate!"

Listening to the little cat demon's reasonable words, Bai Ye suddenly laughed, shook his head and said, "Okay! By the way, my mother-in-law passed on to me the 'Tibetan Heavenly Machine' treasure technique, and I also want to ask Qixue for advice. ”

Although Bai Ye broke through the Jindan Realm and completed the main purpose of this retreat, he was not prepared to leave the retreat immediately.

Instead, he continued to retreat and get started with the few treasures he was now mastering.

These treasures include the two treasures of 'Hidden Heavenly Machine' and 'Borrowing Things for Form' passed down to him by Elder Fox, as well as the inheritance of space treasures he obtained from the 'Cave Xuan True Scripture', which are: Teleportation, Space Slash, Space Shield, and Space Seal!

With the improvement of his cultivation, the control of the power of space has become an instinctive talent, and the space treasure techniques that can be mastered have become more and more space means, from the offensive 'space slash', to the defensive 'space shield', to the escape 'teleportation', and the auxiliary 'space seal', the ability has begun to become more and more comprehensive and diverse.

As for the 'yin and yang' and 'life and death' treasures, he needs to wait for him to go to the sect after he gets out of the customs and look for them from the door to see if there are any suitable treasures.

After a good celebration with the kitten demon, Bai Ye asked the kitten demon for advice on the 'Hidden Heaven Machine' treasure technique, and finally figured out how to practice.

After that, Bai Ye continued to practice retreat, but this time it was for the sake of practicing treasure arts.

The first choice of treasure is naturally the technique of 'borrowing things for the form' that he has coveted for a long time, and the 'borrowing of things for the form' that the fox elder passed on to him needs to rely on his natal magic weapon to refine a 'sub-treasure' for the 'substitute' and 'substitute for death'.

This 'sub-treasure' is naturally not something that can be refined at will, and it must be in harmony with his natal magic weapon.

Just like Bai Ye's natal magic weapon is a combination of 'Yin-Yang Mirror' and 'Kunlun Mirror', which contains the power of yin and yang, life and death, and space, then the sub-treasure and sub-mirror he refined, if you want to be compatible with the natal magic weapon, the materials you choose must naturally contain the power of yin and yang, life and death, and space.

Moreover, the higher the grade and better the quality of the spiritual material of the refining sub-mirror, the better the effect of 'substitute form' and 'substitution of death' of the refining sub-mirror will naturally be better.

Because of the natal magic weapon, Bai Ye has also collected some spiritual materials that contain the power of yin and yang, life and death, and space over the years.

It's just that most of these spiritual materials are only low-level spiritual materials of the Yellow Rank and Xuan Rank, and there are only one or two kinds of Earth-level spiritual materials, and there are no Heavenly Rank spiritual materials.

After all, whether it is yin and yang, life and death, or spatial attributes, spiritual materials are all rare attributes, and spiritual materials are already scarce.

If Bai Ye hadn't practiced the way of yin and yang, life and death, and space, and had the intention of collecting these spiritual materials, I am afraid that it would be difficult to even have a few of these low-level spiritual materials.

brushed the spiritual materials in his hand, but Bai Ye frowned slightly, a little dissatisfied.

Although it is mainly based on those low-level spiritual materials of the Xuan and Yellow ranks, it can also be refined into a secondary mirror of 'substitution' and 'substitution of death', but the effect can naturally be imagined.

This is a life-saving thing, naturally there is no room for compromise and sloppiness, in case the effect of 'substitution for death' is a little worse and fails to fully work, then it will be too late for him to regret it.

The low-level spiritual material made Bai Ye unsatisfied, and his gaze couldn't help but turn to look at the Fusang tree on the side.

This is a spiritual root, and the branches on it are all earth-level spiritual materials, and even the heart of the tree is a heaven-level spiritual material, and it contains two attributes, yang and sheng, which naturally meets his requirements.

You only need to find the corresponding Yin and Death attribute ground level spiritual materials, as well as some space attribute spirit materials, and you can refine the 'secondary mirror' based on the ground level spiritual materials, so that the 'secondary mirror' can even reach the level of magic weapons.

This level of 'secondary mirror' is temporarily enough for the white night.

As for the earth-level spiritual materials of the Yin and Death attributes, Bai Ye did not have them in his hands, but he believed that there would definitely be no shortage in the hands of the Dark Night, and the other party had conquered almost the entire 'Skull Plains' in the underworld, and there must be a lot of high-level spiritual materials collected, especially the spiritual materials of the Netherworld were all Yin and Death attributes.

At the beginning, when refining puppet cannon fodder, most of the low-level spiritual materials used were yellow-level and Xuan-rank, after all, what was refined was only cannon fodder puppets with foundation-building strength, and they didn't use too good spiritual materials.

And the dark night can provide so many low-level spiritual materials, and it is natural that it will not be good for the high-level spiritual materials of the earth level or even the heaven level in his hands.

As for the spatial attribute spiritual material, Bai Ye's first thought was to take out the shattered 'White Bone Cave Heaven' on the Skull Plain.

Although most of the shattered 'White Bone Cave Heaven' had been condensed into the 'Pure Yin Boundary Bead', allowing the White Night Ascending Natal Magic Weapon to be used, there should be some space fragments and scattered Cave Heaven Origin there, which would be enough to collect.

Therefore, it is better to go to the underworld first!

At the moment, the white night opens the yin and yang channel, and passes through the space passage to the underworld.

This was the first time he had crossed the spatial passage after advancing to the Jindan Realm, and the power of the space around him was all under his control, as if he was walking in an ordinary world, without the slightest abnormality or discomfort.

Even, Bai Ye could be sure that even if there was a small shock in the spatial passage at this time, he could quickly calm it down and pass it safely.

The power of space is already an instinct that he is proficient in.

When he arrived in the underworld, Bai Ye had already informed Yu Ye through the 'puppet mark' that the other party had also prepared the spiritual materials and waited for him to arrive.

Even, even the space fragments and the origin of the cave heaven scattered in the 'White Bone Cave Heaven' had already been collected by her, and in her hands, there was no need to waste time in the white night to find and collect.

After handing over the prepared spiritual materials to Bai Ye, Yu Ye asked again: "Bai Ye, when exactly are we going to the puppet realm?" You have been delayed for more than a year, and Wuxiang and Seven Kills may be able to recover from their injuries at any time!"

"When the time comes, this foundation can't stand it, and this spatial passage is exposed, it's not my fault!"

Bai Ye nodded, he naturally knew that time was pressing, and said, "I have broken through the Jindan Realm now, and when I have completed the few treasure techniques I need, I will immediately go to the puppet realm, there are still three months at most!"

Hearing this, Yu Ye immediately nodded and agreed: "Okay, just three months!"
