There were some gaps in the middle of this thunder ball, and Han Yu could see that the surrounding scenery was rapidly receiving.

There are no human beings in the depths of the Poison Barbarian Mountain Range, and the spirit wood here stands tall, although it is only a quick glimpse, these are all good woods for hundreds of years!

Of course, but no other monsters were encountered in the process.

The demon cultivator who led the way in front turned around and took a look, and found that Han Yu was looking left and right at the surrounding scenery, but he didn't say much.

After about a meal, the thunder ball stopped in the air, and after a slight shock, it slowly revealed downward.

Han Yu looked down and saw that this was actually a very large cliff, the color was actually jet black, and there were many traces of thunder strikes on it. But the thunderball did not fall on the cliff, but fell to the bottom of the cliff, and with a light finger of the demon cultivator's hand, a huge black stone gate appeared in front of him. The blue light on the stone door was flowing slightly, and at first glance, it was extremely prohibited.

"Here, this is Lei's cave. The demon cultivator rushed to the stone gate a little, smiled and said.

Han Yu saw the thunder and lightning on his body dissipate, floating in the air and tied, waiting for the senior to speak.

The cyan light curtain in the stone door slowly dissipated, but the stone door slowly opened.

The demon cultivator didn't bother with Han Yu, smiled at him and entered the cave mansion on his own. Han Yu thought of the astonishing speed of this demon cultivator, even if he used the machine armor to escape, it would be useless.

So Han Yu obediently followed and entered a dry passage.

This passage is full of colors, Han Yu saw that the stone walls on both sides were inlaid with high-grade original stones of the five elements, and all kinds of spiritual lights reflected each other, which looked very gorgeous.

"Little friend, please!" Demon Xiu saw that Han Yu's eyes were constantly rolling, and said indifferently.

In fact, as a demon beast, he didn't care about these primordial stones, they were all tributes given to him by some intelligent demon beasts in the Poisonous Barbarian Mountain Range. These things didn't work for him either, so they were embedded in the passage.

Han Yu looked at the high-grade rough stones on the wall, and wanted to knock these things down and put them in his pocket and take them away, but he really didn't dare in front of this demon cultivator, so he followed hard.

This demon cultivator didn't kill him just now, and he shouldn't kill him now.

After turning a few corners, I came to a pearl inlaid with dragon's eye, spirit stones, and gemstones of various colors inlaid on the wall, which were very severely decorated.

In one corner of the hall, there are some red corals, in front of the coral is a white and crystal jade table, and several chairs carved from a whole piece of jade, and in the center there is a giant ding, on which there is also a finger-thick black incense candle, and there is a fragrance in the room.

The demon cultivator entered the cave mansion and did not invite Han Yu to sit down, but went to a passage next door.

Han Yu was left to dry, but he was not annoyed in his heart, thinking about the factors that were beneficial to him.

Before Han Yu could come up with a strategy, footsteps came from the passage on the side.

Han Yu hurriedly looked up.

I saw a palace nun coming out of the passage, with an elegant appearance and skin like snow, who was actually a beautiful woman with a national color and fragrance.

Han Yu thought to himself that this guy might be the lady who was called in the mouth of the demon cultivator just now, a demon cultivator who cultivated to an extremely terrifying level.

"Hehe, little friend, please take a seat!" The woman was followed by the demon cultivator who asked his wife to sit at the jade table, and he also sat on a jade chair with a big stab, and then beckoned to Han Yu.

Han Yu didn't say anything, and also pulled up the chair and sat aside, but the female cultivator's gaze was always on her.

"Xiaoyou smiled, I invited you over, I don't know your surname yet. The demon cultivator said with a smile.

"Under the surname Han. Han Yu hesitated, but said slowly.

"Hehe, it turned out to be Han Xiaoyou, in fact, you should have guessed something, the thunderbird on your body should be the heir of us. If it weren't for that, I wouldn't have let a human enter the forbidden land of the Poison Barbarian Mountains. The male cultivator said with a solemn face.

Han Yu smiled bitterly a few times, but did not speak.

If he really asks about the relationship, he may let him hand over the Thunderbird, and if he refuses directly, he may even attract the anger of these two demon cultivators.

But it didn't work if he didn't answer, so Han Yu used his divine thoughts to make the thunderbird fly out.

The Thunderbird flew out of her arms, and the nun saw that the Thunderbird's face changed slightly.

With a move of her jade hand, an invisible force swept the Thunderbird over, binding the Thunderbird in her hand and caressing it carefully.

"This can't be!" said the nun's tone was full of surprise.

The nun poured a bolt of lightning into the Thunderbird's body, and thunder patterns poured out of the Thunderbird's body, which looked extremely gorgeous.

"Han Xiaoyou, can you tell me how you met my heir?" The male cultivator saw the female cultivator's face, but he already knew it in his heart, and said with a smile.

"This...."Han Yu hesitated.

"Hehe, Daoyou saved our young son and let him have the power of thunder and lightning in his body. We and other couples are very grateful to our fellow Daoists. The demon cultivator turned his head and glanced at it, and then said seriously.

"Actually, the juniors don't know that he is a thunderbird, but a demon bird I befriended was handed over to me and let me take care of it. Han Yu thought about it for a moment and said slowly.

"Well, I see. When my husband and wife encountered a strong enemy back then, they had no choice but to send them out. The demon cultivator nodded slowly.

"I see. Han Yu was stunned, but nodded slowly.

"It seems that Daoist friends really have some adventures, and it is very difficult for human monks to stimulate the origin of thunder in their bodies. He has to go through the test of thunder and fire to degenerate, he has experienced two baptisms of thunder and fire, you are a little monk in the foundation building period really do it, it is really not simple. The demon cultivator nodded approvingly.

Naturally, Han Yu would not truthfully explain his trip to the secret place, and listening to his tone, he didn't mean to get to the bottom of it, Han Yu smiled embarrassedly and fell silent.

The nun also confirmed that the Thunderbird was her bloodline, raised her head slightly, and spoke.

"It's our bloodline, and I ask Xiaoyou to stay by my wife's side and let me wait to train me, and I will compensate for your kindness. Whether you want high-level exercises, human magic weapons, talisman treasures, we and our husband and wife will provide you, and you can also ensure that you can advance to the Dan. The nun promised a lot of things in one breath.

Hearing these good things casually said by the female cultivator, Han Yu's heart quickened a little, especially when he couldn't hear that it was to ensure that he entered the Yudan, which made his heart flutter.

But in exchange for a spirit beast that has always had infinite potential, Han Yu's heart was still a little reluctant. But he also thought about it, he had no way to refuse, everything depended on the meaning of the thunderbird.

The Thunderbird had already opened its mind, and immediately fluttered its wings in the thunder light, and let out a soft cry from its mouth. I don't know how it used to communicate with the nun, and her face changed slightly.

Immediately after Han Yu felt a flower in front of him, the woman came to Han Yu's side and grabbed his arm unceremoniously.

Han Yu only felt a majestic spiritual power surging in his body, his blue thunder aperture was spinning wildly, and Han Yu's face became a little pale in fright.

The female cultivator checked it, and her jade face suddenly became gloomy.

At this time, the Thunderbird broke free of lightning and stood on Han Yu's shoulders again, as if he didn't have too deep feelings for the so-called parents.

The male cultivator's face also changed slightly, and the two of them quickly transmitted a few words, and the hall suddenly fell silent again.

Han Yu, as the existence with the weakest cultivation, of course did not dare to speak first.

After a full meal, the nun smiled bitterly.

"That's it, that's it. Since the thunder in his body is opened for you, if I forcibly keep you by my side, it will be extremely detrimental to your future growth. The nun said helplessly after a while.

Han Yu was ecstatic when he heard this, he could hear the meaning of these words and let the Thunderbird continue to follow him.

However, Han Yu thought about it, what kind of magic weapon did he just promise, can he honor these benefits of his advanced knot pill together?

"Han Xiaoyou, I now want you to make a Heavenly Dao Thunder Oath. After the nun said this, her face turned gloomy again.

"Heavenly Dao Thunder Oath?" Han Yu listened with confusion.

But his reaction was very fast, and he immediately agreed with his fists.

"The only oath I made you swear was that you would never sign a blood pact with my son at any time. Even if you fall one day, my son will lose some vitality at most, and he will not be buried with you. A cold light flashed in the nun's eyes, and she said lightly.

"It's nature. When Han Yu heard this, he breathed a sigh of relief in his heart.

The Thunderbird was now connected to him, and he had never wanted to put any blood pact on the Thunderbird. The effect of that thing is to explode all the spirit beasts when they die, which is not very significant.

The male cultivator saw that Han Yu agreed very happily, his face was also slightly softened, and he took out a page from his body that kept flashing thunder, and threw it casually.

"Drip your blood and make the vow. The nun said very calmly.

Han Yu happily dripped a drop of essence blood, and then made this so-called thunder oath.

As soon as the words fell, the pages full of thunder turned red in an instant, and Han Yu felt something in his body beat rapidly, but quickly regained his composure.

"If you break your oath, when you marry Dan and baby, the thunder will increase dozens of times. Even if you have your human infant by your side, you will not escape death. The male cultivator explained quietly.

"Now I'll give you two conditions, and you can choose one of them. Seeing that Han Yu's face had not changed in the slightest, the female cultivator also relaxed slightly, and said coldly.

"First, my wife and I will take you to the vault where we are waiting and let you choose three things. The nun and the man glanced at each other and said slowly.

Han Yu's heart was surging when he heard this, this couple was a demon cultivator at the Yuan Infant level, and there must be a lot of valuable good things in the cave mansion.

Seeing that the female cultivator had just said what magic weapon and exercises, Han Yu's mood was excited, and she would definitely be able to get a lot of benefits from going in.

Although Han Yu wanted to agree, he still planned to hear the second condition.

Seeing Han Yu waiting for a moment, the female cultivator saw that Han Yu was calm and did not immediately agree, and her eyes couldn't help but show approval.

"The second is that my wife and I can give you a token, and if you encounter a strong enemy, my wife and I can strike once. The nun said coldly
