This time, after more than four months outside, I finally returned safely again.

In fact, before coming back, Yang Dingtian was very worried about seeing the devastated scene.

Because, the tearing space had undergone drastic changes, and at that time, the world of Xiao Xitian also collapsed and fell, and Yang Dingtian was very worried that this would affect Xiao Xitian's movement cycle, which would make the junction between Xiao Xitian and the First Dark Realm advance, and the bloom of the dark rift earlier.

If that is the case, the Demon King Xuyan Wentian will enter the human realm in advance, and his demon fox army will also invade in advance.

That's it!

Fortunately, none of this qiē happened.

Although the entire human kingdom is extremely tense and completely heavily guarded, the destruction has not yet begun!

Naga Frost is reluctant to land in Cloud City, and is unwilling to have any contact with humans other than Yang Dingtian, especially Yang Dingtian's wife.

Therefore, she proposed to go to the First Dark Realm in advance.

Yang Dingtian agreed, this is also beneficial, in case the dark rift blooms early, it will not be defenseless.

So, he didn't enter Cloud City first, and after putting down the Vulture and Poison Sha into Cloud City, he took Naga Frost and continued to fly to the ice and snow.

Then, using the Void Crack, he crossed the abyssal border, and Yang Dingtian and Naga Frost entered the First Dark Realm.

At this time, there are less than ten days left before the bloom of the dark rift.

This time the Dark Rift will be released in the northeast corner of the First Dark Realm, which is about more than 1,700 miles away from the border of the Second Abyss.

Naga Frost, just wait here!

After bringing Frost to the location, Yang Dingtian did not leave immediately, but used his soul sword to dig a comfortable stone chamber, complete with a stone bed and a stone table.

And then. He also brought a lot of different clothes.

When Naga Shuang'er saw Yang Dingtian preparing for this qiē, her beautiful face moved slightly, as if she wanted to say something, but she didn't say it after all.

"Then I'll go back to Sky City first, and I'll be with the Sea Serpent Empress in a few days. "Yangding Heavenly Dao.

"Well, good. Naga Frost said. Then the boat got out of a long golden dress and sat cross-legged on a stone bed.

Yang Dingtian left the First Dark Realm as fast as possible and returned to Cloud City!

......

After returning to Cloud City, Yang Dingtian didn't have time to enjoy family fun with his wife and children, so he entered the energy prison as soon as possible and carried out a cold ice jade coffin.

Inside, is the thousand-year-old fire spirit body of the Demon Spirit Demon Fire, the Ice Spirit, this body that is at least the peak of the saint level.

Yang Dingtian handed the cold ice jade coffin to Queen Poison Sha and said, "Sasha." I'm sorry you just came home and asked you to leave again. ”

Queen Poison Sha pursed her lips and smiled, "I'll go and get back quickly." ”

The vulture on the side said, "Husband, I'll go with Sister Sha." ”

Yang Dingtian nodded.

Then, the two of them, Poison Sha and the Vulture, carried the jade coffin of the ice spirit, using the fastest speed. Fly towards the southeast sea.

At this time, both of them were already saint-level powerhouses. In about three or four days, you can reach the ruins of the Demon Capital and hand over the body of the ice spirit to the Sea Serpent Empress.

Actually, this body should have been delivered by Naga Frost, and she was the fastest, arriving in less than a day.

But now. It's hard to drive the most powerful race of all time.

......

After Poison Sha and the Vulture left, Yang Dingtian immediately found the Demon Fox High Priest who had the deepest research on soul swords in the Demon Fox Clan.

Then, Yang Dingtian said his key.

The Demon Fox High Priest said, "I have indeed seen some of Mr. Void Piaoyan's writings, which mention the theory of the Yin and Yang Dual-System Soul Sword. But in these theories. And it has not been confirmed. ”

Yang Dingtian said: "I know that when Mr. Void wrote these theories, he was actually writing the fourth-order Great Yin Yang Technique of the Pig Killing Sword Technique. The Yin and Yang Dual Soul Sword is also a derivative theory of the Great Yin and Yang Technique. However, after the completion of the fourth-order Great Yin Yang Technique of the Pig Killing Sword Technique, the Void Teacher did succeed in forging the Chaos Emperor Soul Sword. ”

The Demon Fox High Priest said, "How did he do it?"

Yang Ding Tiandao: "In the record, he first forged a Yin Soul Sword of the Near Emperor Grade, plus the original Yang Soul Sword of the Near Emperor Grade. However, the two soul swords are combined into one!"

The Demon Fox High Priest said, "That's okay, it's impossible, isn't it? Even if the two are physically one, they can't achieve the energy of one." ”

Yang Dingtian said: "In the library of the New Naga Empire, I saw the teacher's record. It is to adapt the Great Yin-Yang Technique into a soul technique, and then use the Soul Sword version of the Great Yin-Yang Technique to transform this combined soul sword, and the Chaos Emperor Soul Sword is achieved!"

The Demon Fox High Priest was surprised and said, "This, this is also okay? Void Ancestor, what a genius!"

Then, the Demon Fox High Priest said, "But Yang Dingtian, I think for you, you already have a sea soul crystal that is nearly a demigod, and you will directly join your masculine soul sword." Not only can your Naga royal sword soul be restored, but it is also more lethal than before. I don't think there's any need to risk forging this Chaos Emperor Soul Sword!"

Yang Dingtian nodded and said, "I know, but if I want to kill the Demon King Wentian, I must use the Dark Xuanhuo to tear apart his qi sea and cause his qi sea to explode." However, my cultivation is too low, and the Dark Flame is not enough to tear through the Demon King's Qi Sea defenses, and I need to use the energy of the soul sword. So, I need to combine the Dark Flame and the Nearly Demigod Sword Soul into one!"

The Demon Fox High Priest's eyes lit up and said, "This, is this what you think of yourself?"

Yang Dingtian nodded.

The Demon Fox High Priest was amazed: "This is also completely genius-like thinking, and it can be completely successful in theory." ”

Yang Dingtian nodded and said, "That's right, however, the Dark Xuanhuo can't recognize the soul sword as the master, so after I channeled the Dark Xuanhuo into the soul sword, its first reaction was to devour a qiē energy, including the sea soul crystal of the soul sword. Therefore, instead of being able to release the sword soul of the dark flame, it will completely destroy the soul sword's sea of qi. ”

The Demon Fox High Priest nodded and said, "That's right, it's true. ”

Yang Ding Tian said: "If you want to change this situation, unless this soul sword, the sea of qi with chaos attributes!"

Suddenly, the Demon Fox High Priest's beautiful eyes lit up!

That's right, once a certain energy enters the Chaos attribute, then it is zero. The dark flames will not be devoured.

In this way, the Dark Flame can be introduced into the Soul Sword, and then the Dark Flame version of the Ten Thousand Swords can be released.

Therefore, in this way, the forging of the Chaos Emperor Soul Sword has become inevitable!

The Demon Fox High Priest pondered the whole process many, many times, and then nodded vigorously, "Theoretically, this is completely feasible. ”

Yang Dingtian said: "It's just that we need to write two scrolls in the meditation world. One is the soul sword version of the Great Yin and Yang Technique, and the other is to introduce the Dark Flame into the Soul Sword, and release the Dark Flame Ten Thousand Swords to return to the sect!"

The Demon Fox High Priest thought for a while and said, "The key is the first scroll, which will take a long time. The second scroll is very short-lived, as long as the Chaos Emperor Soul Sword is forged, and then the Dark Xuanhuo is channeled in, it doesn't even need to change too much to the Ten Thousand Swords Returning Soul Technique. ”

Yang Dingtian said: "We have less than ten days left, is it enough?"

Last time, Yang Dingtian and the Demon Fox High Priest adapted the Ten Thousand Swords of the Naga Royal Clan's Sword Soul to return to the sect, but it took a few ten days.

And this time, it's only been less than ten days!

The Demon Fox High Priest nodded and said, "Enough, it's completely enough!" Last time, we stumbled and stumbled, and we didn't know how many unjust roads we had taken. This second adaptation doesn't take that long at all. ”

Yang Ding Tiandao: "Okay, let's do it again, and then use the martial arts wisdom of the realm of the gods to create a greater miracle!"

"Come!" said the Demon Fox High Priest.

......

After deciding down, Yang Dingtian immediately used the fastest speed to go to the underground world of the Yin-Yang Mirror.

Then he was directly there, using the impact of the Billion Spirit Demon Fire and using 999 10,000-year-old Xuanbing Cold Gold to forge a near-emperor soul sword of exactly the same grade!

Of course, this soul sword only has one shell.

Then, Yang Dingtian was under the Yin-Yang Mirror and collected a Thousand Thousand Miles of Xuan Vein Essence on the spot.

There are tens of thousands of this Xuan Vein Essence.

Yang Dingtian spent a few hours, one by one, into the sea soul crystals of nearly demigods.

Suddenly, a complete energy center was completed.

The Xuan Vein Essence and the Sea Soul Crystal immediately began to flow energy.

Then, Yang Dingtian was carved as if carving, transplanting the Xuan Vein Essence into the Yin Soul Sword one by one.

transplanted the sea soul crystal into the hilt of the soul sword, and regarded it as a sea of qi.

Suddenly, a feminine soul sword that was close to the emperor was completed!

In the end, Yang Dingtian used the dark Xuanhuo to create an isolated space!

Then, in this space, the two soul swords were completely melted, and finally completely fused together.

After fusing together, the two soul swords were twice as thick.

Yang Dingtian used Xuanhuo to bombard, bombard, bombard, bombard!

Hundreds, thousands, tens of thousands, hundreds of thousands!

After countless frantic bombardments.

The two Yin and Yang dual-system Near-Emperor Soul Swords were suddenly completely fused together.

An Emperor Soul Sword appeared in front of Yang Dingtian's eyes.

This is probably the only emperor soul sword in the history of post-martial arts civilization. (To be continued......)
