After exiting the cave with the teleportation circle, Bai Yan and Huo Lie went to other caves to explore one by one.
There is basically nothing left in the other forked caves.
Some of them have disappeared under the erosion of time.
After walking through so many side holes, Bai Yan could see that this mine, including all the side holes inside, could not have been dug by miners from outside.
It has been here for countless years.
Perhaps this entire black iron vein appeared because of these things that were originally hidden here.
By chance, this mine was discovered.
Except for Qin Song, perhaps no one has ever reached the end before.
Even those who walked by force were dead!
On the way out, Bai Yan was still shocked.
However, his strength is still too low, and he still doesn't know what kind of secrets are buried here.
"Husband, you can't go out yet."
At this moment, Yuechan suddenly spoke.
"The innate cold air behind that stone door is leaking out more and more.
It must be sealed first.”
Hearing this, Bai Yan immediately stopped.
"Does anything else happen to the Son of God?" Huo Lie asked with some confusion.
"Elder Huolie, please go out and wait for me first. I have to go back." Bai Yan looked a little serious.
Then he said: "You don't have to follow me this time."
After saying that, without waiting for Huo Lie to say anything, he turned around and returned.
"Son of God..."
Huo Lie shouted and was about to follow, but thought about it and gave up.
He could tell that Bai Yan wanted to get rid of him deliberately.
He knew that Bai Yan had many secrets, some of which he didn't want him to see.
With a hint of worry on his face, Huo Lie didn't go out and chose to wait on the spot.
On the way back to Shimen, Bai Yan also keenly discovered that the cold air had become much stronger in such a short period of time.
"Why is this happening?" Bai Yan looked solemn.
"Maybe it has something to do with you taking away the black blood on the stone door."
Yuechan's voice was slightly deep, and she added: "Do you still remember what we told you about the horror of the congenital cold body?
If the innate cold body cannot control the innate cold energy in the body, it will be a disaster.
I just remembered that the cold energy of the innate cold body that died here has most likely exploded.
It's just that it was forcibly sealed by this tomb, so it didn't cause disaster."
At this point, Bai Yan understood what Yuechan said.
His expression became more solemn.
The blue stone door has cracked and the cold air is leaking out. If it is not dealt with, the innate cold air inside will break out sooner or later.
But then it will still be a catastrophe.
Yuechan added: "The innate cold body here is approaching perfection. If the cold air is allowed to burst out, the entire Xihuang State and even the lands beyond will be devastated."
If you haven't met, forget it. Now that you have met, Yuechan, as the Lord of the Moon and the one who controls the power of the lunar calendar, will not just sit idly by.
Facing the increasingly strong cold, Bai Yan once again came to the end.
This time, before he even got close to the stone gate, he had to use the True Sun Fire to protect his body.
"Sure enough, without the obstruction of the black blood, the cold air can penetrate more smoothly."
After getting closer, Bai Yan could clearly see the cold air seeping out along the cracks in the stone door.
If he was directly hit by the cold air that had just seeped out, the true sun fire on his body would dim directly.
"So strong!"
Bai Yan said to himself in surprise.
But at this time, there were no outsiders present, and Yan Xi and Yue Chan flew out directly.
Yuechan looked at this situation with some solemn eyes.
If she was in the heyday of her physical body, these would naturally be child's play, but now it's a bit tricky.
"Madam, is it possible to follow the sealing technique in the "Taiyin Manual"?"
When she sealed Jiang Xiaoyu's cold energy before, Yue Chan had already imprinted the method on Bai Yan's mind.
He wanted to do it by himself, after all, the last time Jiang Xiaoyu was sealed, Yuechan slept for a year, and he didn't want to let this happen again.
However, Yue Chan shook her head: "No, the cold air is stronger this time, and what's sealed this time is not the person, but the door.
With your strength, you cannot exert the true power of the True Fire of the Fierce Sun and the Extremely Cold Ice, so we need to take action ourselves."
After saying this, she looked at Yan Xi: "You and I join forces."
"good."
Yan Xi didn't say much.
The matter is serious and it is not the time for bickering.
"What about me, what can I do for my husband?"
After hearing Yuechan's words, Bai Yan immediately became worried.
I once again hated myself for not being strong enough.
Although he has only practiced for nearly two years, he has become invincible in a county. He is already a truly peerless genius.
But in front of the two ultimate boss ladies, he always felt like a waste.
But at this time Yuechan smiled and said: "Of course, the matter of sealing cannot be separated from my husband.
We are just soul bodies, and we cannot perform many secret techniques, so we need to use your body."
"But this time my husband will have to endure pain."
Hearing this, Bai Yan's eyes immediately lit up.
"Okay, okay." He nodded immediately.
As long as I can protect the two ladies from falling into a deep sleep.
It's just a little pain, but he, a big man, can bear it!
After saying this, the two Yanxi girls returned to Baiyan Dantian.
"Husband, relax your mind and let me control your body." Yan Xi's voice sounded.
The possession was successful the next moment.
Two sacred and ancient breaths suddenly rose up from Bai Yan's body.
This time Yan Xi and Yue Chan were possessed together, and each of them occupied half of Bai Yan's body.
Trinity!
"This time, the three of us, husband and wife, joined forces. Yuechan and I activated the Lieyang True Fire and the Extremely Cold Ice.
Husband, it’s up to you to fuse the two powers together." Yan Xi said.
Bai Yan is a fierce yang body of ice, and he has long been proficient in the fusion of ice and fire.
"good."
Bai Yan was slightly nervous.
Immediately, two powerful rays of true sun fire and extremely cold ice suddenly rose up from his body.
Yan Xi and Yue Chan took action personally, and this scale was no longer the petty fight he had used before.
The level is much higher than the ice and fire he can control.
The powerful power of ice and fire surged through his body, and the pain hit him instantly.
But then he concentrated all his efforts and merged the two forces together.
When Yan Xi and Yue Chan took action in person, the power of ice and fire was too strong for him to control.
Then the two women controlled Bai Yan's left and right hands and quickly performed seals, guiding the power of ice and fire fused by Bai Yan to flow towards the stone gate.
After the fusion of ice and fire, its quality and power more than doubled.
Under the influence of the two women's secret skills, they were engraved on the stone gate like an inscription.
"Chichi!"
When it comes into contact with the cold air, it makes a hissing sound.
Immediately, red and blue patterns were printed on the stone door.
As time went by, Bai Yan's body continued to tremble, and he was really suffering a lot.
If Yan Xi and Yue Chan weren't controlling his body, he wouldn't have collapsed.
But he still insists on integrating the power of ice and fire.
After a long time, the two girls finally channeled the power of ice and fire to carve the entire stone gate with patterns.
The next moment, the lines on the stone door suddenly lit up.
The red and blue light condensed on the stone door, creating a virtual shadow of the word "Feng" in ancient seal script.
Then the shadow dissipated, and the cold air on the stone door no longer leaked.
"Finally, are you okay..."
Those two sacred auras disappeared from his body.
Fatigue and pain came flooding in.
Bai Yan murmured, and his eyes fell into darkness.
