Wan Fo Mountain seems to have never had such a lively scene as today, even in the most prosperous period of Wan Fo Mountain, there have never been so many people fighting, bursts of roaring sound in Wan Fo Mountain, like thunder, there is blood sprinkled in the sky, stained to the ground, adding a bit of blood.

But in a cave in the Ten Thousand Buddha Mountain, Lei Yu was not affected in the slightest, he opened his eyes, stretched his muscles, in this Ten Thousand Buddha Mountain for decades, Lei Yu could not get out of the Ten Thousand Buddha Mountain at all, and it was impossible to absorb the dragon qi, and life could be described as very difficult.

However, with the existence of the Yin Netherworld, Lei Yu still absorbed a small amount of dragon qi, and as a result, Lei Yu's current cultivation has been promoted to the realm of half-step immortal thunder, which can be said to be one foot into the immortal thunder stage.

Even if it is a raging flood outside, I will not move, Lei Yu will not care how lively the fight is outside, now he is already in the depths of Wanfo Mountain, and he wants to absorb everything about dragon qi, but this is not his ultimate goal, what he wants to get is the dragon core.

"Senior, now that the dragon vein of Wanfoshan has been completely formed, you see if it's time to go and find the dragon core. Lei Yu's face showed a hint of yearning, it was the dragon core, but it was the core of a dragon vein, gathering most of the essence of the entire dragon vein.

If he obtained the dragon core, he would definitely be able to advance to the Immortal Thunder Stage and become the top existence of the Thunder Continent, instead of fleeing in embarrassment in the hands of the powerhouses of the Immortal Thunder Period like he is now.

In front of Lei Yu, a dark shadow emerged, still with that old face, but with an irrepressible smile.

"Don't worry, I've already used 'Dragon Hunting' to find the location of the dragon core, but now is not the best time to capture the dragon core, with the defensive power of the dragon core's periphery, even if you and I join forces, we may not be able to break it. Therefore, you must wait for a while now, and wait until those Immortal Thunder Stage powerhouses arrive before seizing the dragon core. ”

Yin Ming said slowly, but what he said made Lei Yu anxious, if he let those immortal thunder period powerhouses come, with his strength, he would not be able to intervene at all, and the biggest possibility at that time would be that he watched the dragon core being taken away by others, and he only had a greedy share.

"Senior, are you playing with me?" Lei Yu's face was a little ugly, at this moment, he really thought that Yin Ming was playing with him.

"Hmph, kid, do you know that there are still too few Dao, do you really think that as long as you find the dragon core, you can take out the dragon core? Not to mention the hard shell outside the dragon core, the thunder power required to stimulate the dragon core alone is far beyond your imagination, at least ten immortal thunder stage powerhouses need to shoot together to activate the dragon core. Do you think you'll be able to get the dragon core?"

Yin Ming said a little unhappily, with a hint of unhappiness in his eyes.

Lei Yu was stunned for a moment, he didn't expect that seizing the dragon core would require such effort, which was completely beyond his imagination.

"Although you won't be able to get the dragon core for a while, there is one thing you can get now, and by following my instructions, you can definitely get more than you can imagine. Yin Ming breathed a sigh of relief and didn't say anything serious, he also understood the eagerness in Lei Yu's heart.

When Lei Yu heard this, he couldn't help but show a curious look on his face: "What is it that can move the seniors?"

"There are three kinds of strange things in the dragon veins that are the most precious, among which the dragon core is the most, the dragon pith is second, and the dragon qi is again. Although the dragon qi is extraordinary, it is only an extension of the dragon vein, and the real essence is still in the dragon core and dragon marrow. ”

"According to my estimate, the dragon core still has seven days to appear, so take advantage of this time to collect some dragon marrow as much as you can, just in case you need it from time to time. ”

Yin Ming said very cheerfully, obviously knowing a lot about the dragon vein. At the beginning, the reason why the Hell Demon Sect was able to rise so rapidly was that in addition to the "Nine Shadows Emperor", more importantly, the "Nine Shadows Emperor" found a broken dragon vein.

The amount of power that that dragon vein can support is extremely limited, but even so, the Hell Demon Sect has also achieved more than a dozen Immortal Thunder Stage powerhouses in a short period of time, and it has become one of the most powerful forces on the Thunder Continent, even the three major dynasties dare not provoke the Hell Demon Sect more.

You must know that among each sect in the Dao, the top position is still occupied by the Immortal Thunder Stage powerhouse, and if you want to cultivate an Immortal Thunder Stage powerhouse, the resources required can simply hollow out a medium cultivator family, so even the strongest sect is only five or six Immortal Thunder Stage powerhouses, and it is rare to exceed ten.

However, a single dragon vein can create such a grand occasion of the Hell Demon Sect, and you can imagine how great the role of the dragon vein is.

Of course, this is also related to the fact that the "Nine Shadows Emperor" completely exhausted the potential of the broken dragon vein. Otherwise, the power contained in the dragon vein could last for at least hundreds of years.

"Senior, what is this dragon marrow?" Lei Yu was not moved, but showed some doubts, he really hadn't heard of the dragon marrow.

"People have bone marrow, and dragon veins naturally have their own bone marrow, which is called dragon marrow. This dragon marrow is hidden deep in the dragon vein, naturally not well known, and the dragon marrow can only be found by going deep into the dragon vein. Therefore, the world's knowledge of the dragon marrow is limited, and only those who are strong in the Immortal Thunder Stage know about the existence of the dragon marrow. ”

"You are in the dragon vein now, as long as you find the flow of the dragon marrow, you can find the dragon marrow, and then you can have as much dragon marrow as you want. ”

Yin Ming said, explaining the strangeness of the dragon marrow to Lei Yu.

At the moment, Lei Yu only felt that his breathing became short, and his heart couldn't help but move, this dragon marrow may not have much effect on him, but it is an extremely precious existence for Elder Tongxuan, Shui Ruohan and others.

Although he can't find them yet, that doesn't stop him from preparing for them. He didn't want to wait until he was promoted to the Immortal Thunder Stage, Elder Tongxuan, Shui Ruohan and the others were still in the realm of the Thunder Dan Stage.

"Senior, let's start now!" Lei Yu's heart moved, and he said with some eagerness, the current time can be described as extremely precious, every moment means that countless dragon marrow flows away from his hands, he doesn't want to delay too much time.

"This dragon vein has just been generated, so the dragon marrow contained in it is still a minority, but I can accurately find the location of the dragon marrow with the technique of 'searching for the dragon and exploring the secluded'. Now, you let go of your mind, and I will transmit what I see into your sea of consciousness, and as long as you follow my steps, you will be able to quickly find the dragon marrow. ”

Yin Ming said, and then a strange picture suddenly appeared in Lei Yu's sea of knowledge, only to see that in this picture, the dragon veins of Ten Thousand Buddha Mountain spread for thousands of miles, all of which were presented in his sea of knowledge. At this time, Wanfo Mountain has completely changed, removing everything from its appearance, leaving only an empty skeleton.

What dragon raised its head, what dragon scales, all disappeared, only a thin line horizontally and vertically, which looked very strange.

"Dragon head, is that the dragon head?" Lei Yu's divine thoughts swept over, and he suddenly found that in the northern land of Ten Thousand Buddhas, there was a dragon head standing only more than a hundred miles away from Lei Yu, although the dragon head was only built with thin lines, but it was full of endless majesty, as if it was a real dragon.

And in the center of this dragon head, a dragon-shaped ball of light fluctuated, which was filled with an endless amount of power, that force was so strong, even with the strength of Lei Yu, his face couldn't help but change, he felt that the amount of power could definitely completely submerge him, and there would be no corpse.

"The dragon head and the dragon core, it turns out that they are really by my side!" Lei Yu muttered to himself, his heart fluctuated, this discovery was really amazing, now he only needs to go more than a hundred miles to really touch the dragon core.

However, Lei Yu also found something strange, there was a layer of hard dragon skin tightly wrapped around the dragon's head on the periphery of the dragon's head, and only by using extremely strong force could this layer of dragon skin be shattered.

"You don't have to think about finding the dragon core now, when the time comes, you will naturally have a chance to get the dragon core. For now, you're still looking for the dragon marrow, and you don't have to worry about the rest. ”

Yin Ming reminded that he was really afraid that Lei Yu would want to take the dragon core.

"Senior, don't worry, I still understand this truth. Lei Yu nodded, although the dragon core is precious, now is indeed not the time to take the dragon core. Instead of being ambitious, it is better to set your sights on the dragon marrow.

His gaze gradually moved away from the dragon core, and Lei Yu was able to completely check the true face of Wan Fo Mountain, only to see that within a radius of thousands of miles, the crystal silk threads were like the meridians of the human body transporting the dragon marrow towards the west of Wan Fo Mountain.

A pool of water appeared in Lei Yu's sea of knowledge, only a radius of hundreds of zhang in size, the pool water is clear, there is an indescribable charm contained in it, although it did not go to the pool water, but Lei Yu felt a different kind of force.

The dragon marrow is not as domineering as the dragon qi, but it is as warm as water, and the amount of power contained in it is much stronger than the dragon qi, and this kind of power is the best for cultivators.

"Thank you for your hard work, fat baby!" Lei Yu smiled slightly, and suddenly a purple light flashed in his hand, and the "Shen Yuan Gun" appeared in his hand.

A tremor came from the "Shen Yuan Gun", and the "Shen Yuan Gun" seemed to be out of Lei Yu's hands as if it was going to be uncontrolled, but soon this tremor subsided, and the fat baby finally stopped, and reluctantly accepted his fate.

As a result, the dignified "Shen Yuan Gun" was used by Lei Yu to dig the mountain, who let him have no tools in his hands, so he could only grieve the fat baby.

A piece of smoke and dust drifted in the cave, and the billowing smoke and dust soon drowned everything, Lei Yu held the "Shen Yuan Gun", swept away with one shot, and soon swept out a large piece of dust, and slowly advanced towards the depths of the mountain range.
