Lakis was thrilled when he heard this, Hua Lei was right, although there are many king-level undead powerhouses in the undead plane, many of them belong to the power, and provoking them may have a lot of obstacles to the establishment of their own power. And those free undead powerhouses are basically undead with flying ability or powerful magic, and it is quite difficult to capture and subdue them. Although the golden chariot can give him the ability to fly, because there is no suitable charioteer, relying on the two-headed flying nightmare, it can only be used to bully those monarch undead who do not have the ability to fly, if it is replaced by the king of the ancient bone dragon or the king of the undead wizard, there is no practical use.

The fourth-order dragon was already a monarch-level top powerhouse, and his territory was in need of powerful flying undead, as an undead dragon knight, the practicality was much better than that of the golden chariot.

Although the Golden Chariot has a bonus to his lightning attacks, it is slow unless he can find a two-headed bone dragon as a coachman.

Thinking of this, Lakis couldn't help but ask, "Your Excellency the Holy Magister, I don't know where your undead dragon is, can you see it!"

Hua Lei smiled slightly, looking here, there was still enough space, and released the dragon that had been frozen all along.

He has been killing these two dragons for a long time, but the situation that can threaten him and let him use these two undead dragons has never appeared, and he is afraid of the power of the Holy See, so he has rarely released them, and he simply exchanged them for the golden thunder chariot depicting the ancient magic array.

The fourth-order ice dragon is six meters tall and twenty meters long. It is really not small among the dragon clan, it looks no different from a living dragon on the outside, extremely fierce, with huge claws and fangs, shining scale armor, two cold breaths constantly swallowing in its nostrils, and bursts of strong dragon breath rippling, showing its incomparably strong strength.

Lakis looked at this dragon and liked it very much, but with his strength, he couldn't tell that it was an undead dragon, and couldn't help asking, "Master, are you sure this is an undead dragon?"

Hua Lei nodded and said: "This is what I have refined with the secret method of the Huaxia Continent, I can retain all the skills of the dragon before his death, and it can also automatically repair the injury, because there is no breath of life, the only thing I am afraid of is the light magic, but the undead plane, there should be no light magic!"

Lakis looked at the huge fourth-order dragon in front of him, only such a giant creature was worthy of his Thunder Giant's size, the more he looked at it, the more he liked it, but the Thunder Chariot was a divine artifact inherited from the Thunder Giant Tribe.

Although he has become an undead, he is still very concerned about the tribe, and he thought about it a little embarrassed for a while before saying, "I wonder if this undead dragon can absorb the soul fire and evolve?"

It stands to reason that undead creatures can absorb death energy to evolve, but this dragon is very weird, and Lakis is not sure.

Hua Lei shook his head and said: "I don't know about this, I haven't tried to let him deal with the undead, but he is already a top powerhouse at the king level, and there can be several emperors in the entire undead plane, you are too greedy!"

Lakis thought carefully for a long time, Hua Lei said well, the strength of this dragon is strong enough, although it is not expressed, but the strong aura that belongs to the fourth-order dragon Lakis can still feel it, Hua Lei is a holy demon master, there is no need to lie to him, he has just defeated Tamik, and he needs strong subordinates to suppress and subdue the forces left by Tamik, carefully weigh it, and then he is a little reluctant to say:" The Golden Thunder Chariot is a treasure given to us by the God of Thunder, and there is a soul-burning flame burning on it, and if the master takes it, I'm afraid it won't be able to use it!"

Hua Lei pursed his lips disdainfully: "Don't worry about this, in the eyes of my great Hua Lei, magic has never been a problem, as long as you give it to me, I have my own way to restrain this flame!"

Lakis looked at Jiajing, and suddenly gritted his teeth and said: "Okay, since the master said so, Lakis has no reason to refuse, but I have a request, I hope Jiajing's friend can agree to me!"

Jiajing nodded and said, "I wonder if there is anything that Lakis needs Jiajing's help with?"

Lachis's voice became low: "I was originally the patriarch of the Thunder Tribe of the Thunder Mountain Range, in a plane war that broke out three thousand years ago, entered the undead plane, unfortunately died, became an undead, I really want to go back to the tribe to see, but unfortunately this body, let me go back without a face, when I left the tribe, I took the patriarch token, I hope Jiajing's friend can transfer it to the current patriarch of the Thunder Tribe for me, and ask Your Excellency Jiajing, in case there is any difficulty in the tribe, I hope to help, Lakis is grateful!"

Jiajing nodded and said, "This matter is easy to do, go back to the Western Regions Continent, I will go there in person!"

Lakis gratefully took out a black statue of the Thunder Giant from his armor and solemnly handed it to Jiajing: "This statue is the prayer of the Thunder Tribe, which can increase the birth rate of the Thunder Tribe's giants, and the Jiajing brothers must take it away!"

Jiajing also said with a serious face: "Lachis, you can rest assured, I guarantee in the name of the warrior that I will definitely send this statue to the Thunder Tribe!

At that moment, Hua Lei erased the magic mark between him and the dragon, let Lakis make a contract with the fourth-order dragon, and then put the Thunder Chariot into his spatial ring.

He was a magical researcher, and if he could understand the secrets of the Thunder Chariot's levitation, he would have a solid foundation for building magically powered aerial warships, and he would always be thinking about the huge machines that could fly in the air as described by Jiajing.

After handing over the little skeleton Hua Lei to Lachis, Hua Lei asked Jiajing for a large number of magic cores, and used a different time and space teleportation to send everyone back to the Western Continent.

Originally, they could use the portal to go back, but the question was that after they were all gone, who would bring the portal back to them, Jiajing didn't want to leave the portal in the Annihilation Realm.

Unbeknownst to them, as soon as they were gone, Lakis took out a few hundred dragon bone grasses and distributed them among his loyal men. Although these dragon bone grasses are of little use to the grand duke and king-level powerhouses, they are very effective in quickly cultivating a low-level undead, although the dragon bone grass is a rare medicinal material, but Lakis has been the emperor for more than two thousand years, how can there be only seventy as few.

The coordinates of the teleportation in different time and space are Badaling, although there is a little deviation, but the location where everyone appears is only ten kilometers away from Badaling, which has to make people admire Hua Lei's strength.

Jiajing explained to everyone, released the red-eyed griffin, and returned to Badaling to make up for it, while he rode the fastest iron-feathered sand eagle and rushed to the imperial capital to deliver dragon bone grass to Gugna Lun.
