Under the protection of the illusory black tower shadow, Lu Zifeng, the mysterious girl, the little leopard, and the Wind Splitting Shenpeng ignored the violent thunder beside them and fell rapidly.

The Thunder Yin Stream is bottomless, and more than a dozen breathers Lu Zifeng and the others have not yet fallen to the ground of the Thunder Yin Stream.

The surroundings of the Thunder Yin Stream are all pitch black, and Lu Zifeng does not dare to walk around, there are too many potential threats here, if you encounter a spirit beast that you can't deal with, you will die here if you are not careful.

In the process of falling, Lu Zifeng's eyes kept sweeping around, expecting to find a way out or a place to settle down here.

Although he was able to continue to urge the illusory black tower shadow, it was not a way to go on like this, and he had to find a way to get out.

Lu Zifeng's eyes saw the Wind Splitting Shenpeng who had been following him, and now that he could resist the thunder here, wouldn't it be much more convenient to go out, and directly asked the Wind Splitting Shenpeng to fly out with him, the mysterious girl and the little leopard.

However, there must be a lot of spirit beasts guarding outside now, and they are waiting to go out by themselves.

Perhaps, this period of time, I have to spend this period of time. After the mysterious girl came to her senses and recovered from her injuries, with her protection, she and the little leopard and the Splitting Wind Shenpeng could leave here directly.

This thought was fleeting in Lu Zifeng's mind, although he was thinking about it, but Lu Zifeng's eyes had been cautiously staring at the surrounding situation, trying to find a place to stay.

After falling rapidly again for more than a dozen breaths, Lu Zifeng's face was happy, in the young man's sight, he could basically see the ground of the Thunder Stream, but at a height of forty or fifty zhang in the Thunder Stream, there was a protruding platform.

This protruding platform had a small hole that led into the walls of the thunderous stream.

Seeing this hole, Lu Zifeng's face showed ecstasy. This cave is a great place to hide. Lu Zifeng could see that there was still a dense thunderstorm on this platform, but in the cave entrance, there was no trace of thunder.

Before the ecstasy on Lu Zifeng's face could spread, as the young man's figure declined, another hole in Lu Zifeng's sight came into view.

Under Lu Zifeng's shocked gaze, a dense hole appeared in his sight. The Thunder Creek is full of these holes. The distribution of these openings is sparse at first, then gradually denser, and then sparser.

Lu Zifeng could feel that the closer he got to the hole in the ground of the Thunder Stream, the more powerful the fluctuations coming from it became.

There must be spirit beasts living in these caves, but Lu Zifeng doesn't know what kind of spirit beasts live in these caves.

Lu Zifeng didn't dare to be careless, and let the Wind Splitting Shenpeng fly to the outermost cave entrance with himself, the mysterious girl and the little leopard.

Soon, Lu Zifeng and the others landed on the platform outside the entrance of the cave, Lu Zifeng had a twelve-point spirit in his heart, and no one knew what kind of spirit beast lived in the cave.

The spirit beasts that can survive in the Thunder Yin Stream, their strength must not be low.

For the sake of safety, Lu Zifeng put the mysterious girl more than ten feet deep into the entrance of the cave, and left the little leopard and the Splitting Wind Shenpeng here.

The Wind Splitting Divine Peng is simply a flying spirit beast, its strength is very low, and bringing it will only get in the way. As for the little leopard, the reason why Lu Zifeng left the little leopard is to protect the mysterious girl, if there is any emergency, the little leopard can also protect the mysterious girl, if the little leopard can't protect the mysterious girl, then Lu Zifeng can't do anything.

After all, Xiaobao's current strength is in the late stage of the Xuandan Realm, and Lu Zifeng is only the strength of the early stage of the Xuandan Realm. After settling the mysterious girls, Lu Zifeng stepped into this cave.

This cave is not as dark as expected, and it may also be the reason why there is a flash of thunder outside the cave entrance, which illuminates the cave.

The inside of the cave was very dry, there was not the slightest musty smell, and there was no smell of spirit animal feces. This makes Lu Zifeng very strange, if it is a spirit beast, most of the spirit beasts will eat and drink Lazar in their own cave, why is there no such unpleasant smell in this cave, maybe these spirit beasts love to be clean, and they will not eat and drink Lazar in their own cave.

The sound of rustling footsteps sounded in the roar of thunder, and soon, Lu Zifeng had already walked to the depths of this cave. This cave is not deep, and the road is easy to walk, a straight road, and there is no place to turn.

In Lu Zifeng's sight, a spirit beast that looked similar to a leopard was lying in the depths of the cave and sleeping.

After getting closer, Lu Zifeng saw the real gaze of this spirit beast, the size of this spirit beast is not large, only one zhang in size, its appearance is very similar to that of a leopard, but its body is covered with silver-white scale armor, and a pair of claws are also covered with silver-white scale armor, which is extremely sharp. Its tail is not unlike the tail of a scorpion. Its eyes were red with a sinister aura, and needless to say, they must have been affected by the flickering thunder here.

Seeing Lu Zifeng rashly breaking into his cave, the Evil Thunder Spirit Beast immediately stood up and roared at Lu Zifeng, shaking the entire cave, and then a huge spiritual power fluctuation came out from its body, and this fluctuation had actually reached the late stage of the Xuandan Realm.

The Thunder Spirit Beast raised its sharp claws and grabbed at Lu Zifeng fiercely. This simple attack may not be able to withstand even the martial artists in the middle of the Xuandan Realm.

Lu Zifeng was shocked for a while, but he didn't expect that a spirit beast he casually encountered in the Thunder Yin Stream would have its strength two levels higher than his own.

This is just the outermost cave of the Thunder Stream, if it is those caves that are close to the bottom of the Thunder Stream, wouldn't the strength of the Thunder Spirit Beasts that exist inside be even stronger?

According to Lu Zifeng's guess, the strongest strength of the Thunder Spirit Beast here is likely to have reached the Divine Spirit Realm, which is not much different from the cultivation of the Golden Yanyi Tiger King outside.

It's just that now Lu Zifeng, the Evil Thunder Spirit Beast in the late stage of the Xuandan Realm, is quite difficult to deal with, and when he encounters the Evil Thunder Spirit Beast at the end of the Xuandan Realm, he has no power to fight back at all.

I can't care about it so much, for now, let's deal with this Thunder Spirit Beast in front of me first.

As soon as the Thunder Spirit Beast saw Lu Zifeng, it immediately launched an attack, which shows how violent this spirit beast is, attacking when it sees someone.

Lu Zifeng hurriedly urged the shadow to take a series of steps, dragging out the afterimage of the Dao behind him, dodging the sharp claws of the Thunder Spirit Beast.

The Shadow Serial Step is only Mahayana martial arts, this level of body martial arts, to the level of the Xuandan Realm, the role is already quite weak, only the middle grade spirit martial arts and above level of martial arts have strong power.

When fighting against the Thunder Spirit Beast, Lu Zifeng can still perform it once or twice. After all, the spirit beast's intelligence is not high, and it can still have some effect, but if it is against the martial artists of the Xuandan Realm, it is really useless at all, and the martial artists of the Xuandan Realm can see through their own shadow at a glance. It is precisely for this reason that Lu Zifeng has long given up the Mahayana martial arts of the Shadow Serial Step.

The young man not only gave up the fan shadow serial step, but also gave up the inch fist that was also a Mahayana martial arts, as for the martial arts of the middle and upper martial arts, Lu Zifeng gave up a long time ago.

Lu Zifeng felt that if he could obtain a high-level body martial arts, his combat effectiveness would definitely be greatly improved.

After Lu Zifeng cast a shadow to dodge the attack of the Thunder Spirit Beast, the young man immediately unleashed the bronze thunder body, and the young man's body suddenly skyrocketed, and at the same time, the young man's complexion also changed from fair to a healthy bronze.

Lu Zifeng felt that when he cast the copper thunder body today, the copper thunder body had a particularly large increase in himself, probably because there was a violent thunder here.

After casting the Copper Thunder Body, Lu Zifeng immediately cast the Dazzy God Spell, which stunned the Thunder Spirit Beast.

In this short period of time, Lu Zifeng quickly unleashed the three-star seal of killing the wolf, and a huge star light seal carried great power and fiercely suppressed the thunder spirit beast.

The Thunder Spirit Beast had just woken up from the stun effect of the Dazzling God Spell, and it couldn't react, and the Three-Star Seal of the Killing Wolf was mercilessly bombarded on its body, and then exploded.

The strength of the Thunder Spirit Beast can only be equivalent to that of an ordinary martial artist in the late stage of the Xuandan Realm, after Lu Zifeng cast the Dazzy God Spell and killed the wolf three-star seal, it had no power to fight back at all, and was blasted into pieces all over the ground, and the blood all over the ground was left behind. The fragments were constantly flickering with a furious thunder, the breath of which was exactly the same as the fluctuations of the thunder that permeated the cave.

On this pile of debris, a thunder ball of light that looked like a heart attracted Lu Zifeng's attention, and the appearance of this thunder ball of light was not much different from that of a human heart. At this time, this thunder ball of light was emitting an incomparably powerful black thunder.

"It's ...... The source of the power of the Thunder Spirit Beast, the Thunder Heart!?"

Lu Zifeng looked at this thunder ball of light with ecstatic expression, and hurriedly put it into the storage ring.

The Thunder Heart is the source of the Thunder Spirit Beast's power, and all the Thunder Power it absorbs is gathered on this fist-sized Thunder Heart. If he had collected enough Thunder Hearts, wouldn't his Nine Tribulation Thunder Dragon Body be able to go any further?

Even if these Evil Thunder Spirit Beasts did not have a Thunder Heart in their bodies, Lu Zifeng could also cultivate the Nine Tribulations Thunder Dragon Body with the unique environment here, but the speed of cultivation would definitely be much slower than refining the Evil Thunder Heart.

What Lu Zifeng lacks most now is time, he doesn't have enough time to absorb the furious thunder here, otherwise, if the young man stays here in the Thunder Yin Stream to cultivate for a year or two, the young man's Nine Tribulation Thunder Dragon Body will definitely be able to cultivate to the fullest.

Originally, the thunder that was all over the thunder in the thunder stream could not be absorbed by the young man. Because the thunder is too violent, once absorbed, not only will it not have the effect of cultivating the Nine Tribulation Thunder Dragon Body, but it will also cause itself to explode and die because of the violent thunder.

However, because of Lu Zifeng's cultivation of the Great Xuanhuang Floating Tu Technique, after the young man cast the second layer of the Floating Tu Technique, he was able to filter these violent factors and absorb the evil thunder here with peace of mind, which was also discovered by Lu Zifeng who had just jumped off the Evil Thunder Yin Stream before.
