Bai Cangdong also wanted to ask the Underworld Reaper why he wanted to kill the Holy Demon King, but he saw the tears of death on the forehead of the underworld Reaper flying towards Bai Cangdong.

Bai Cangdong had just caught the tears of death, but the body of the god of death in the underworld suddenly exploded, leaving nothing behind except a holy light undead egg.

"What message does the Underworld Death want me to kill the Holy Demon King? This doesn't make sense at all, the Death Realm is forbidden to be entered by the King of the Nine Sequences, and it is impossible for the Holy Demon King to enter the Death Realm, let alone have an entanglement with the Underworld Death, but for what Underworld Death not only knows the Holy Demon King, but also kills the Holy Demon King?" Bai Cangdong was full of doubts in his heart, but unfortunately the Underworld Death God blew himself up too early, and no one could give him an answer.

Leaving the Death Realm with a lot of questions, this time the harvest is also extremely rich, not only got the light of life, but also got two kingly weapons, one is the conch-like instrument of the demon, called "The Note of Mirage", which is a sound system of the king's weapon, and the other is the "Tears of Death".

The Tears of Death were originally holy things, but after returning to the body of the Grim Reaper, they turned the Grim Reaper into a holy white, but it itself turned into a gray-black color that shimmered with a ghostly light.

And the introduction of the tears of death is also very simple, just say that it is the master of the underworld, the tears of the god of death, and in addition to this, there are only four words of the king's armament, and I don't know what the use of the road is.

There is also a huge harvest is the undead egg of the god of the underworld, but the price required to hatch this egg is extremely high, and several of these materials, Bai Cangdong has never even heard of it. I don't know when I will be able to hatch it.

"What kind of immortal is the Holy Demon King?" Bai Cangdong played with the tears of death. The curiosity about the Holy Demon King in my heart is getting heavier and heavier.

The Sword of the Underworld in the Sword Emperor space suddenly emitted waves of thoughts. It turned out to be the tears of death in Bai Cangdong's hands.

"I forgot that you are also an immortal of the underworld, and this Tears of Death should be of some use to you. Bai Cangdong casually sent the Tears of Death into the Sword Emperor space, anyway, this thing is useless to him, if the Sword of the Underworld can borrow this thing to ascend to the king level, it will be of great help to him.

The potential of the Sword of the Underworld is undoubted, but it is only because the title has always been too low that it has not been able to play a powerful role. Bai Cangdong has been thinking of a way, hoping to make the Sword of the Underworld be promoted to the king level.

After the tears of death entered the Sword Emperor space, as if they were attracted, they flew towards the underworld sword, and landed directly on the hilt of the underworld sword, which was closely connected with the hilt, as if it should have been embedded there.

A stream of ghostly light flowed out from the tears of death, surging into the whole body of the underworld sword, gradually wrapping the underworld sword in a dark light, making the underworld sword enter a state of transformation.

"It was a bonus. "Bai Cangdong doesn't know how far the Dao Underworld Sword can transform. However, it needs to be an eighth-sequence Underworld Reaper, and nine times out of ten, it should be able to directly top the Underworld Sword to the king level.

In addition to these gains. Naturally, there are also Mei Yanfeng and the Buddha Destroying King, Bai Cangdong sent him to Yujiatian first, and then returned to the Rebel King City alone.

Bai Cangdong hesitated again and again, but still gave the light of life to the peerless killing sword to use, although giving the light of life to the demon of the sword mound or hooking away the jade demon may create another king of the ninth sequence, but a forcibly promoted ninth sequence, how can it compare to the peerless killing sword, the strongest person in the world.

The most important thing is that Bai Cangdong also needs the immortality technique of the peerless sword killing.

The peerless killing sword in the transformation absorbed the light of life, and the light cocoon suddenly flashed with a strange brilliance, and the sword light burst out from the light cocoon like a thunder python electric snake, causing cracks to appear on the light cocoon one after another.

Rumble!

A long sword with an earth-shattering murderous aura broke out of the cocoon, and the once invincible peerless killing sword finally reappeared in the world again.

Bai Cangdong was secretly delighted, so much energy was finally not in vain, the peerless killing sword was born, and he could finally get the immortality technique of the peerless killing sword as he wished.

The immortality technique of the peerless sword killing is called "The Sword Sutra of Absolute Killing", after Bai Cangdong got it, he immediately began to study it, and turned over and over a sword scripture and studied it for a long time, Bai Cangdong felt that there should be no problem, except that there were some small places that needed to be modified, which should be able to be used to cut off the chain of order.

However, when Bai Cangdong really went to cultivate, he found that although the "Killing Sword Sutra" did not require a lot of modifications like the "Chaos Sword Sutra", it was not so easy to get started, after all, his foundation was completely different from the peerless killing sword, and at least three or four percent of it had to be modified before he could turn it into an immortal technique that was truly suitable for him.

"Since it needs to be modified, let's solve it all at once. Bai Cangdong took the "Killing Sword Sutra" as the basis, and added some of the things he had learned from the "Chaos Sword Sutra" and the immortality technique of the Demon of the Sword Shrine to the "Killing Sword Sutra", which naturally caused many problems, Bai Cangdong found some other sword immortality techniques as a reference, and gradually modified the "Killing Sword Sutra" into an immortality technique that really only belonged to him.

It took Bai Cangdong more than two years to revise and complete the basic part of the "Killing Sword Sutra", in fact, this long life technique can no longer be called "Killing Sword Sutra", because the part that belongs to the "Killing Sword Sutra" can only occupy forty percent, and the part of the "Chaos Sword Sutra" also occupies two percent, the immortality of the demon of the sword mound accounts for one percent, and some other sword immortality techniques that Bai Cangdong uses for reference also occupy one percent, and two achievements are modifications made by Bai Cangdong's own foundation, and after completion, they are the same as the original "Killing Sword Sutra" It's a big difference.

"This long life technique can no longer be called the Sword Sutra of Absolute Destruction, it should be given a new name, what is the name?" After Bai Cangdong completed the basic part, he was in a very happy mood, and even had a great interest in such inconsequential details.

It's just that Bai Cangdong thought of a lot of names by himself, but he didn't feel very satisfied, and he had to give up for the time being.

"What kind of name can be obtained by this kind of longevity technique, it also depends on chance, and now I can't think of a satisfactory name, it should be that the opportunity has not yet arrived. Bai Cangdong let go of the idea of naming the Immortal Technique and began to cultivate this Immortal Technique.

Bai Cangdong was still a little reluctant at first, after all, the immortality technique in the world is not very common that can coexist, not to mention that it is such a first-class immortality technique in the world, it is more likely to be cultivated at the same time, if this longevity technique is cultivated, I am afraid that the "Bayeux Sutra" will also be abandoned.

However, when Bai Cangdong really began to cultivate, he was pleasantly surprised to find that while he was running the new immortal technique, the Bayeux Sutra could still operate freely and was not affected in the slightest.

"Now that the cultivation time of the new immortal technique is still short, I don't know if there will be any impact on the Dao in the future, if it can really be cultivated dually, it will be really great. Bai Cangdong was pleasantly surprised, but he was a little worried that it would have an impact in the future.

The benefits of the Bayeux Sutra are so great that if he is not really unable to find the follow-up part, he will not abandon the Bayeux Sutra.

After the foundation of the Immortal Technique is completed, all that remains is to modify and explore when cutting the Order God Chain, which can only be carried out when the time comes, but there is no way to modify it now.

Bai Cangdong cultivated the new immortal technique with peace of mind, and at the same time had free time, only then did he remember that he still had a lot of things to do.

He hadn't gone to the mysterious ancient city left by the first king of the world that the Heavenly Calamity King had said, and the even more mysterious cloud castle on the first order of darkness, Bai Cangdong had never had time to explore it again.

In other words, Bai Cangdong has always been a little wary of the mysterious cloud castle, and even if he had time before, he didn't dare to go to the cloud castle easily.

"Let's go to the ancient city left by the first king of the world first, I don't know what the male lord of the Lu Dao generation left in that ancient city, and dare to leave the person who wins this city to win the world, such arrogant words. Before Bai Cangdong left, he still went to the Council of Elders first.

For more than two years, he would often go to see the little girl who looked very much like Xixi, but now he can be sure that the little girl is by no means Xixi, because she has not always maintained the appearance of a little girl like Xixi, but like an ordinary person, she has grown up slowly over time, and now she is eleven or twelve years old, just like Bai Cangdong.

It's just that Bai Cangdong has not been able to find out why the Great Elder would raise this girl in a bamboo house, and also gave her the name Xixi.

What made Bai Cangdong even more puzzled was that although the Great Elder was very kind to this girl, it could be said that as long as the girl wanted something, even if it was the moon in the sky, the Great Elder would not hesitate to take it off and give it to her, but he had never taught the girl anything like immortality and martial arts, and it seemed that he had no intention of letting the girl embark on the path of cultivation.

"Wouldn't it be sad if this girl died after only living for two hundred years?" Although the girl is not really embarrassed, but over the years, Bai Cangdong has seen her as if she had seen a miserable person, although he had never said a word to the girl, but he couldn't treat the girl as a real passerby.

Bai Cangdong hesitated in his heart, whether to take the girl away from here, now that the Great Elder has left the Rebel King City, it is a great opportunity for him to take the girl away now.

It's just that Bai Cangdong is worried that the girl will treat the Great Elder as a real mother back then, and may not go with him.

"What the hell is it like outside?" the girl sat in front of the window, holding her chin with her hand, and her eyes seemed to be looking at the flowers and plants outside the window.

"Xixi, do you want to go out and take a look at the world world outside?" Bai Cangdong's heart moved, and he appeared and walked into the bamboo house. (To be continued......)
