Qing Yu felt this strange state of his body, and he was speechless in surprise, but he didn't want to stop this state, he didn't like this state, but he was afraid that his slightest movement would interfere with Bai Ling's actions.

So, he began to seriously watch Bai Ling's various operations.

Bai Ling was worthy of being a real immortal before her death, although she never said that she was a true immortal, but through her various words and deeds, it could be seen that she was a true immortal.

All kinds of operations flowed smoothly, as if she had refined this magic weapon countless times, no matter when to add materials, when to increase the flame, when to decrease the flame, it was all flawless.

Qingyu was amazed, and for a while he forgot that it was Bai Ling who controlled it, oh no, it was affecting his body to do these things.

This magic weapon is so thick that it was created by Bai Ling according to the refining method on the fragment of the "Tianque Jade Book", and it is strictly an imitation.

However, the magic weapons recorded in the "Tianque Jade Book" are all super magic weapons that the true immortals in the sky may not be able to refine, and the success rate of imitating such magic weapons with alternative materials that can be found in the human world is really pitiful.

Fortunately, Bai Ling had already deduced the refining method in her mind countless times, otherwise even she would not be able to do it so skillfully.

Bai Ling's operation speed was getting faster and faster, Qing Yu could clearly feel that his mana was being consumed in large quantities, a large amount of sweat beads were flowing from his forehead, and the light of those spirit stones on the surrounding magic circle was getting dimmer and dimmer.

Bai Ling also released the ice scorpion and asked it to help replace those used up spirit stones, in just two hours, dozens of spirit stones had already been spent, and these spirit stones were all medium-grade spirit stones with good quality and fineness.

Time passed minute by minute, and in the blink of an eye, another two hours passed.

Finally, Bai Ling couldn't hold it anymore, sat cross-legged on the ground, and exchanged the control of his body to Qing Yu to let him recover his mana, but he returned to the Yin Death Space and tried his best to absorb the Yin Ghost Qi to recover some soul power.

Yin Ghost Qi was helpful for Bai Ling to recover his soul power, but it wasn't very big.

The temperature of the Yin Flame has now reached several thousand degrees Celsius, and the temperature of this secret room has also reached a high temperature of nearly seventy degrees, if it weren't for Qing Yu's use of the "Human and Ghost Combination", Bai Ling applied a layer of ice shield to him, he would have been scalded to death.

Although the ability of immortal cultivators to withstand the environment is far beyond that of mortals, this temperature is not something that ordinary foundation building period monks can withstand.

......

In this room, a few hundred meters down, there is a separate house, this house is still a few hundred meters away from the secret room above, yes, the secret room that Qingyu is now in is the deepest place that can be lowered in the usual way during the entire foundation building period.

And this house is surrounded by a yin flame, but it can't be burned out, you know, the yin flame at this temperature has reached more than 7,000 degrees, and the steel will be turned into thick water, and the dock stone can't withstand such a high temperature.

This place, this depth, is not only dangerous because of the temperature of the Yin Flame, but also because of its instability, the temperature is slightly lower than here for the monks of the Yudan Period, but it is stable and usable, and the flames here are of no use value.

This house is still very large, more than 300 square meters, and it is also a wonder in the yin flames, but unfortunately no one can see it.

Inside the house, the decoration is very good, and the building of the Ghost Spirit Sect outside is a style, and it is more luxurious, and the most important thing is that the various things used are quite precious.

In the hall of the house, a middle-aged man with a masculine and handsome appearance is drinking the green tea in his hand.

This is the legendary "Lingming Green Tea", which only grows in the Lingming Terrace, that is, the most dangerous place where the spiritual world and the underworld are handed over, it is very precious, a cup of such tea, in the eyes of those in need, this is a priceless treasure, it is immeasurable, if you really want to compare, this cup of tea is comparable to half the value of those materials in Qingyu's hands now!

The man looked at a mirror in front of him with interest, this mirror was different from ordinary copper mirrors, more like that kind of glass mirror, but how could there be glass in this world.

But it happened so strangely, and no one could explain what it was in the man's hand.

What appeared in this mirror was not his own, but the scene in Qingyu's room now, this little guy was so interesting, it was the first time he had seen such an interesting little guy since he was sealed in this ghost place.

Of course, this fun does not mean that it is really interesting, but that Qingyu's chance is really not small, in the world of cultivating immortals, if you want to succeed, that is, to ascend to immortality, then the most critical one is chance, the greater the chance, the greater the possibility of your ascension.

The man's hand rested on the mirror, but as if it had some kind of magic circle, a bolt of lightning burst out of it and reached his finger, and he withdrew his hand as if he had been electrocuted.

The man smiled bitterly, shook his head, and muttered, "I really didn't expect that this seal is still so powerful after so many years, it really deserves to be your masterpiece, hehe." ”

......

Bai Ling and Qingyu rested for a while, and then continued to start refining, and after another two hours, the two of them rested again, and then refined again, and there was a rest.

It wasn't until a week later that Bai Ling completely returned to the Yin Death Space, and Qing Yu looked at the thick water in the furnace, not knowing what to say.

It's not that Bai Ling doesn't want to continue, it's that his and her soul power and mana are not enough to support it, if one of the two people can reach the knot stage, they can refine it, but now they can only stare dryly.

However, Bai Ling came up with another idea, that is, to let this thing continue to be roasted here, and before leaving, he put spirit stones in various places where the spirit stones were injected, which was enough for this magic circle to scorch for three months according to the temperature of the flame that Qing Yu wanted.

After three months, even if the two of them have not reached the stage of knotting, they can still refine it, so now there is only one question left, how to make this room belong to them within three months?

Qingyu can't stay here for three months, he still has his own things to do, so there is only one way left, find a way to rent this room.

He remembered that Li Fa shouted a senior at that time to activate the teleportation circle, so this place was managed by people.

So Qingyu shouted to the sky, "Senior, I have something to discuss with you, please meet!"
