Yin Shiyin took another bite at Wu Kun's ear, and Wu Kun screamed again in pain. In the end, Wu Kun finally gave in and offered his soul suppression hands.

"Hmph, I've finally learned to be obedient, next time I provoke me, I'll bite you to death!"

"Don't dare, don't dare, let's talk about the Heaven Swallowing Demon Skill. ”

Yin Shiyin's eyes widened, and she asked, "Do you dare to mention that incident?"

"No, no, how dare I, how can I blame you for that thing? Even a genius like me has only comprehended two, how can I blame you if you don't understand? Sister Shiyin is very talented, and she is just a little worse than me, the most important thing is that the Heaven Swallowing Demon Skill is too pitted, and even the countless complicated runes can't be read by even immortals. ”

Yin Shiyin squinted her eyes and smiled, "Then what exactly do you want to express?"

"I mean, we can discuss the mystery together! With my ingenuity and your natural talent, isn't this a simple magic feat?"

"Go on!"

"I'm done. ”

"This sycophant is good, but I like to listen, aren't you extremely smart? ”

"Uh...... There is no ......"

"And you've been farting with me for so long?"

“......”

"Don't talk nonsense with you, I'm going to cultivate, you can comprehend the treasure technique yourself, I'm afraid that you won't make any progress when I break through." ”

"How is it possible? I'm very talented and brilliant...... Wu Kun said to himself, Yin Shiyin didn't listen to it at all......

Yin Shiyin took out the bones of the strong man and ran into the big array to cultivate, she first looked at the bones carefully, and the divine aura was intoxicating.

When she guided the pure energy in the bone marrow of the bones into her body and refined, she felt that her cultivation had made a slight progress, although the progress was not very obvious, but if she could continue according to this trend, it would not be long before she advanced to the perfection of the five internal organs, and during this time, Wu Kun might not be able to make any progress. After all, he had been meditating for two days, but he had no clue.

Wu Kun plunged headlong into the world of ancient runes, the ubiquitous runes really gave him a headache, all of this was completely impossible to start, and he didn't know how to start cultivating, but Wu Kun firmly believed that there must be some secret to the cultivation method of the Heaven Devouring Demon Skill, if it was really to comprehend all the runes here, it would be impossible at all!

After another ten days, Wu Kun really had a headache this time, and then he realized what a happy thing it was to have a master to lead the way.

On the other side, Yin Shiyin's body had already condensed a lot of crystal spiritual power, and the pure evil qi in that skeleton was also reduced by as much as one-third, and it wouldn't be long before she could break through.

"Oh, it's distressing! I didn't know that it was that senior who created such an esoteric exercise, and I didn't know if there was anyone else who had learned it besides him?

That stone box was upside down in Wu Kun's hand, without any mechanism, and without any lines and symbols on it, it was just an ordinary box, but it was such an ordinary box, when you probed into the spiritual sense, it would be blocked by dozens of powerful breaths.

Wu Kun didn't believe in this evil, he planned to physically destroy this box, he took out one of the seven evil swords casually, and then slashed it with all his strength, as a result, the divine sword collapsed, and the surface of the box was as bright as new, and there was not even a single sword mark.

But Wu Kun didn't fail to find that when he encountered a fierce attack, an extremely dazzling light lit up on the surface of the box, and it was that layer of light that protected the stone box, and after the light, everything returned to normal.

"It's just strange, there is definitely some big secret hidden in this! This aura is full of twenty paths, and each one is extremely obscure and powerful!" Just feeling a little bit, there was a trace of coolness in the depths of Wu Kun's soul.

Wu Kun then tried a few more times, the result was the same, he carefully felt the seals left by those powerhouses, and that feeling was like being targeted by the super flood desolation relic, stronger than any aura he felt, just like the level of the White Tiger Saint King......

"Oh my God...... What the hell is in this? Twenty Saint King-level powerhouses have joined forces to set up seals! Yes, I can't get the idea of this stone box at all, there is no way to take it at all, I feel that it is more hopeful to study the Heaven Devouring Demon Skill. ”

Just as Wu Kun was about to enter the world of runes again, he glanced at Yin Shiyin, who was absorbing pure evil qi next to him, and the skeleton that was slowly becoming dim caught Wu Kun's attention.

"Wait, we seem to have ignored a question from beginning to end, who is this person, why does he have so many good things, and it is the Heaven Swallowing Demon Skill and the stone box sealed by the twenty Saint King rank powerhouses. ”

This thought cheered up Wu Kun, he carefully studied this skeleton, down to each of his bones, but this skeleton did not have any scars all over his body, at the vertebrae of the skeleton, Wu Kun found a drop of dark golden blood remaining in the spine of the skeleton.

This drop of blood flashed with a dark golden light, Wu Kun carefully took it out, took out a jade bottle of extremely high quality, carefully took it out and put it in.

"This person's bloodline must be extremely noble! His background is extremely extraordinary, but why did such a person die in the Demon Tablet Domain? Why did no one take the ring from him after he died?"

All this is so unbelievable, and the identity and death of this person carry a great mystery.

"What are you doing?" Yin Shiyin opened her eyes and looked at Wu Kun in confusion.

"I'm studying this skeleton, do you notice any differences?"

"What's the difference?"

"Did you notice any difference after absorbing the pure death qi from these bones?"

Yin Shiyin felt the breath on her body again, and then said, "No?"

"Is there really nothing special?"

Yin Shiyin felt it again, and this time she really found something different: "It seems to be ...... My spiritual power...... Sublimated ......"

"What sublimation?"

"I can't tell, it's ...... anyway There's a different feeling...... I've gotten a lot stronger......"

"In what ways?"

"The spiritual power has become different from before, I seem to be stronger! Also, the runes in my body...... It seems to have changed a few times......"

Yin Shiyin materialized his spiritual power and gathered it in his palm, and Wu Kun also condensed his spiritual power in his palm.

Although the aura emitted by Wu Kun's spiritual power is stronger than Yin Shiyin, in terms of the purity of spiritual power, Wu Kun thinks that his spiritual power is very pure, but compared with Yin Shiyin, there is still a trace of deficiency. Yin Shiyin's spiritual power, at this time, there is no trace of the magazine, and it is another kind of refinement, as if it has a special spirituality!
