Drilling into the cave, Yang Fan found that the tunnel was longer than he thought.

After thinking about it, Yang Fan knew that this was because his body shape was too different from the body shape of the Silver Horn Han Python, and there was an error in the distance in his memory, but for him who had a seven-trick exquisite heart and could see things darkly, no matter how long this tunnel was, there would always be an end.

Half an hour later, he finally passed through the tunnel and got out of the water.

In front of him, there was a wide stone wall, on the stone wall, carved with several human figures, a cursory glance, Yang Fan felt a little familiar, but soon, his eyes were attracted by a wide sword in front of the stone wall.

The sword was dark and looked unremarkable, but Yang Fan felt that the sword was as heavy as a mountain, although he didn't pick it up, and he didn't even touch it, but he had such a feeling in his heart.

At the same time, the egg in his arms trembled slightly, as if he was familiar with the sword.

Yang Fan walked over, walked to the wide black sword, put down the python egg in his arms, and looked at it carefully.

Yang Fan was stunned for a moment, stretched out his hand to hold the hilt of the sword, and forced, but did not pull it out, and then forcefully ...... When Yang Fan exerted all his strength, the sword moved slightly.

Although he still hadn't pulled it out, Yang Fan also understood in an instant that this sword was probably just an ordinary giant sword, and there was nothing strange about it.

Thinking of this, he looked up at the mountain wall in front of him.

A humanoid picture on the mountain wall comes into view.

"This, isn't this the pattern on the Six Yang True Solution?"

Yang Fan was stunned for a moment, and hurriedly took out the booklet hidden in his arms, and before he could turn it over, he saw that the graphics on the booklet suddenly moved.

At the same time, the figure on the mountain wall moved.

The faster and faster it moved, faster and faster, and in the end, all the human figures turned into one, and the booklet in Yang Fan's hand exploded and turned into powder, while the stone wall in front of him slowly opened.

"What is this—What kind of fuss is this?"

Yang Fan was stunned, he never thought that a booklet of the Six Yang True Solution would actually be able to open the mountain wall in front of him.

Liuyang is really solved!

Could it be that this is the secret cave of Pure Yang Sword Immortal Li Daotong?

In an instant, Yang Fan's eyes became hot.

Without saying a word, he took a big step forward, but then he stopped.

Fixedly looking at the cave where the mountain wall opened.

Inside, there was a faint pale yellow glow, and a cold air came to the face, and the cold air was very cold, and this coldness, from the body, from the soul, seemed to be able to freeze everything, anything tangible and intangible.

"Huangquan Nuan Jade!"

Yang Fan was shocked.

Inside the cave, a layer on the ground, is full of pale yellow Huangquan warm jade, the so-called Huangquan warm jade, which comes from the Yellow Spring, the netherworld, a small piece of Huangquan warm jade, contains endless Huangquan cold.

No wonder, no wonder that after the silver-horned cold python entered here, it was promoted to the fourth order, it turned out to be the cold qi of the Yellow Spring in this Yellow Spring Warm Jade, which stimulated the bloodline of the Yellow Spring Cold Snake King in its body!

Yang Fan, who knew it in his heart, was even more surprised at the same time, these Huangquan warm jade, through the cave, can stimulate the bloodline of the silver-horned cold python outside the mountain wall, so here, if you go here, what will be the change?

Will he directly turn into an ice corpse, or will he become the King of the Yellow Spring Cold Snake in one fell swoop?

Just thinking about it, Yang Fan noticed a trace of Huangquan cold air and was dragged over, and the one who pulled the Huangquan cold air was the egg laid by the Silver Horn Han Python.

This egg, in the memory of the silver-horned python, came inexplicably.

It didn't mate with any male pythons, because it was the only one here, the silver-horned python, and those black anacondas, which were lower in rank than it, couldn't be interested in it at all.

The first time I felt the presence of bone blood in my abdomen was after entering this place.

That time, the silver-horned Han Python, which had already entered the threshold of the fifth-level demon beast, came here to transform, but the result was that not only did it not succeed in its transformation, but its strength dropped greatly, and it had bone and blood in its belly.

This makes it very strange that although the spirituality is high, but the wisdom is far less than that of the human silver-horned python, but the nature of the mother, so that it does not resist the existence of this child, as the days get longer, the stronger its maternal love for the child in the womb, the more it wants it to be born safely.

This is also the reason why the silver-horned python will not hesitate to hurt itself again and forcibly give birth to this egg before it explodes.

Now, this egg is so strange, it can pull the cold qi of Huangquan before it is born, which makes Yang Fan even more curious in his heart, what is going on with this egg, is it some ancient demon spirit, reincarnated?

Thinking of this, he walked over to the python egg.

"No matter how you came here, since you chose to follow me, then I will accept you. ”

Yang Fan swiped his fingers, and on his arm, a blood mark was cut, and a stream of blood gushed out.

All the blood fell on top of the big egg, and it wasn't until the whole egg was submerged that Yang Fan stopped the wound.

"Fortunately, I sucked the blood of the whole black anaconda before, otherwise it would be a little insufficient now. ”

Feeling a slight weakness on his body, Yang Fan carefully drew strange runes on the egg.

He can't have true qi spiritual power in his body, and if he wants to form a contract with demon beasts, he can only choose the blood contract, which is the most original contract between heaven and earth, and it is also the most unbreakable contract.

The big egg seemed to sense something, and suddenly trembled violently.

Not only that, but the big sword inserted in front of the mountain wall also trembled with the same frequency, as if it was about to fly out.

Yang Fan was shocked in his heart, and the speed of his attack was even faster, fortunately, he inherited Li Changfeng's memory, and Li Changfeng was also the best at this kind of blood contract rune, and soon, the rune condensed.

Big Egg fell silent instantly.

Greatsword was also silent.

Immediately afterwards, the blood that Yang Fan poured on the egg began to integrate into the egg body, as if it had been absorbed, and disappeared little by little, and with the disappearance of all the blood, the blood contract was formed.

Yang Fan's mind seemed to have a connection with this big egg, and at the same time, when he looked at the big sword again, Yang Fan actually had a feeling that he could master it.

Could it be that the formation of this egg has something to do with this sword?

At this moment, no matter how sluggish Yang Fan was, he also noticed that there seemed to be some kind of connection between the big egg and the black big sword, but he didn't make a judgment immediately, but walked towards the big sword.

As soon as his hand approached, the big sword jumped out on its own and fell into Yang Fan's hand.

This sword is very heavy, I am afraid it weighs more than a thousand catties.

Although Yang Fan has nearly 20,000 jin of strength, it is also a little difficult to swing this sword, every time he slashes, he has to use all his strength to do it, however, this sword is so heavy, but it can also make up for some weaknesses that he has no true qi in his body.

"Good sword!"

After waving a few times, Yang Fan smiled and praised.

Inserting the sword back into the ground, Yang Fan's hand left, and a thick reluctance appeared in his heart, as if he had lost the most precious treasure.

"It looks like I'm going to get along with this sword day and night in the future. ”

With a wry smile, Yang Fan lifted the sword again, and after thinking about it, he tore off a strip of cloth and tied the sword to his back.

Now, it's a lot easier.

After doing this, Yang Fan's eyes once again fell on the cave mansion that was suspected to be a pure yang sword immortal, Li Daotong, and covered with Huangquan warm jade.

"I'm afraid this is really the cave of the Pure Yang Sword Immortal, otherwise, who can have such a big deal to pave this entire cave mansion with Huangquan warm jade, which is very rare in the Yellow Springs Netherworld?"

Instead, Yang Fan laughed: "What am I doing here to guess so much?

Facing the cold air blowing on his face, Yang Fan stepped into the cave.
