In order to obtain the spirit blood of the demon ape, Zhang Yifan did not let those four-star demon insects devour the corpse of the demon ape.

He looked around the scene and found that at this time, except for the corpse of the seventh-level demon ape that he forcibly left behind, the rest of the demon beasts were devoured by the demon insects.

Zhang Yifan checked the number of demon worms and found that in the end, nearly 100 three-star demon worms had advanced to four-star demon worms, and more than 700 three-star demon worms were still alive.

In this battle alone, he killed nearly two hundred three-star demon worms.

The main thing is that at the beginning, there were many deaths in the battle with the group of demon apes.

However, it is worth getting more than a hundred four-star demon insects, and the power of these advanced demon insects is extremely improved, and they are not afraid of dealing with seventh-level demon beasts at all, and the damage is very small.

In order to cultivate the three-star demon worm, Zhang Yifan also worked hard, consumed a lot of resources, and finally got the harvest.

He deliberately collected some of the advanced four-star demon mother worms that seemed to be full of potential, and planned to focus on cultivating the eggs that would be conceived in the future.

The first is to replenish the number of demon worms, and the second is to increase the potential of demon worms and give birth to demon worms with purer blood.

Of course, this process is relatively long, and it cannot be done overnight.

The advanced four-star demon worm behaved so powerfully, Zhang Yifan couldn't help but look forward to the performance of the five-star or even six-star demon worm. I plan to spare no effort to cultivate the Demon Worm.

In addition, Zhang Yifan also discovered some drawbacks in the use of magic insects.

Aside from the drawbacks of being easy to backlash and making the owner more bloodthirsty and murderous, the divine consciousness consumed by the advanced demon insects seems to be too great.

Zhang Yifan found that he had been able to drive ten three-star demon worms before.

And with his current divine sense, it would be very difficult to drive nearly a hundred four-star demon worms at the same time, and he would soon run out of divine sense.

He was already aware of this situation, so he would not be disappointed.

The strength of the four-star demon worm far exceeds that of the three-star demon worm, even if it is a hundred four-star demon worms, it is much more powerful than the previous thousand three-star demon worms.

If he could still drive so many demon insects after these demon worms advanced, no one would be his opponent at that time, and even the Yuan Infant Stage cultivator might retreat.

But this is obviously unrealistic, if this can really be the case, then wouldn't it be that the world of cultivating immortals is all the world of insect cultivation.

And this is not the case, although insect cultivation is difficult and powerful, it is not impossible to deal with, there are many ways to restrain insect cultivation, among which sword cultivation is the natural enemy of insect cultivation.

Moreover, it is not easy to cultivate insect beasts, and the resources consumed by insect beasts of a certain scale are dozens of times that of ordinary spirit beasts, which is far from what ordinary monks can afford.

If Zhang Yifan hadn't had an extraordinary opportunity over the years and accumulated a lot of resources, he would have had a lot of trouble feeding these demon insects.

Previously, Zhang Yifan could only barely be regarded as half an insect cultivator.

The main reason for cultivating demon insects is to collect evil qi, followed by one more means to deal with the enemy, plus he has some extraordinary means to prevent demon insects from counterattacking, so he made up his mind to cultivate demon insects.

I didn't expect him to really let him cultivate an advanced demon worm, and now he is already a real insect cultivator.

Whether an insect cultivator is strong or not depends on whether the insects and beasts it controls are powerful, and the second is to see the level and number of insects and beasts it controls.

Whether the insect beast is powerful or not depends on the strength and bloodline of the insect beast itself, the three-star demon insect itself contains a trace of the bloodline of the ancient demon insect and the nine-star blood demon worm, and the strength is extraordinary.

The level and number of insects and beasts are related to the cultivation of the insects and beasts themselves, and the strength of the monk's divine sense. And the latter is the most direct factor.

Therefore, the strength of the divine sense is an important basis for evaluating an insect cultivator, and it is also the basis for using spirit insects as a means of attack.

The more powerful the divine sense, the more insects and beasts will be controlled, and it will also inhibit the backlash of insects and beasts.

Zhang Yifan is currently benefiting from his own special divine soul and the help of Miao Lian, and his divine sense is far beyond that of ordinary Jindan stage monks, and he is naturally handy at driving insects and beasts at present.

After packing up all these demon worms, Zhang Yifan hurriedly rushed towards Xiao Hei.

At this time, Xiao Hei couldn't afford to be seriously injured, and the damage he received was relatively large, and he had already hurt his vitality at all.

Zhang Yifan swallowed some healing pills for him, but he only barely let him recover one or two, and if he wanted to return to his previous state, he didn't have a good way at present.

"Xiao Hei, how do you feel?" Zhang Yifan said.

"Master, I'm fine, I'm able to recover slowly on my own now, but I don't think I can help my master fight in a short time. ”

"It doesn't matter, you can recuperate at home first. Your demon yuan is seriously damaged, can this be recovered?" Zhang Yifan asked again.

"I guess I can only recover some, I need to devour the fire-attribute spirit grass, preferably like the previous kind of condensing flame grass, or the fire-attribute demon pill, so that I can recover a little faster, and I can also accumulate the foundation. ”

"Okay, when I'm done with this, I'll let you eat enough. ”

"Thank you hosts. Xiao Hei said happily, and then was admitted to the mysterious space by Zhang Yifan.

"Xiaobai, how are you?" Zhang Yifan asked Xiao Bai, who was healing, when his divine sense entered the mysterious space.

"It's not a big problem, I should be able to survive the catastrophe in half a year after I recover. ”

"Are you sure about the tribulation?" asked Zhang Yifan with some concern.

"Well, it shouldn't be a big problem. Master, I want to spend my time here, and this place seems to suit me better. ”

Xiaobai's words made Zhang Yifan a little surprised, but after thinking about it, he understood.

This valley contains a large amount of yin and evil qi, which is relatively similar to Xiaobai's own breath, and if you cross the tribulation here, the ascension will be even greater.

However, because the thunderous aura contained here is also very strong, it is estimated that the power of the Heavenly Thunder Tribulation encountered by Xiaobai will be even greater at that time.

In this regard, Xiaobai said that it was not a big problem, it had a way to resist the thunder tribulation, and after breaking through the bottleneck, Xiaobai's strength increased greatly, and after the transformation, his strength was even more direct to catch up with the seventh-level Dacheng Demon Beast.

And because of the bloodline, Xiaobai's strength is at the top of the demon beasts of the same level.

Because there were still a lot of materials for making the mine-guiding platform, Zhang Yifan finally agreed.

However, Xiao Bai's time to cross the tribulation needs to wait for him to find the Xuanyin Evil Thunder Vine and clean up this valley at the same time.

After confirming the status of his two spirit beasts, Zhang Yifan began to deal with the scene.

He collected the corpse of the seventh-level demon beast and deliberately set aside the spiritual blood of the eye to keep it alone. Then he eliminated the obvious traces of the fights and other things at the scene.

After dealing with the scene, Zhang Yifan began to replant the advanced four-star demon insects and ban them, and used the Divine Soul Secret Technique combined with the Insect Control Secret Technique to re-control these faintly out of control four-star Demon Worms.

The final result made Zhang Yifan very satisfied, most of the four-star demon insects that had been re-controlled became very obedient, only a few still resisted, Zhang Yifan did not hesitate to kill them with a ban, so as not to affect other demon insects.

After dealing with the matter of the demon worm, Zhang Yifan continued to explore the depths of the valley.

When passing by the big tree where those demon apes were, Zhang Yifan found that this was a spirit tree with Yin Thunder attribute.

Although he didn't know what kind of spirit wood it was, he had already seen that these spirit trees could be used whether it was to make thunder attribute array flag materials or some magic weapons, which were quite valuable, so he naturally accepted them all unceremoniously.

It's a pity that he didn't find the Xuanyin Thunder Vine in this area.

He wasn't worried about this, generally speaking, as long as the area where the Thunder Demon Ape existed, there would be a Xuanyin Thunder Vine. Moreover, this valley is not small, he can't see the end with his fiery eyes, and there are still many places to explore.

After traveling nearly fifty or sixty miles, Zhang Yifan came to a new area in the valley, where more than ten groups of Evil Thunder Demon Ape still appeared, among which there was also a seventh-level Evil Thunder Demon Ape as the leader.

Because he already knew more about these demon apes, Zhang Yifan was relatively easy to deal with this time, and without dispatching spirit beasts, Zhang Yifan only lost more than a hundred three-star demon worms, and wiped out all these demon apes.

In the end, nearly 100 three-star demon worms were transformed into four-star demon worms.

After a short rest, Zhang Yifan continued to explore.

After walking for nearly fifty or sixty miles, Zhang Yifan found another area where the Thunder Demon Ape existed.

It's still a relatively easy battle.

After dying nearly 100 three-star demon worms and harvesting more than 100 four-star demon worms, Zhang Yifan wiped out all these demon apes.

Encountering the Thunder Demon Ape three times in a row, and getting more than 300 four-star Demon Worms, this did not make Zhang Yifan happy, but his expression became a little dignified.

Zhang Yifan found that this valley seemed to be extraordinarily long and endless, and he had walked nearly two hundred miles now and had not seen the end, and every fifty or sixty miles there would be a wave of thunder demon apes.

In addition to this, he also found that he was not walking on a straight path, but like a whirlpool, he should be walking in circles.

And until now, he hadn't found the Xuanyin Thunder Vine. It stands to reason that he should soon discover this companion spirit material, but the Xuanyin Thunder Vine did not appear in his field of vision.

This is not normal.

However, now that Zhang Yifan has greatly increased his strength with the help of the four-star demon worm, he has the confidence to continue to investigate.

Then he encountered five waves of Thunder Demon Ape beasts one after another, and the last wave of them also appeared with an eighth-level Thunder Demon Ape.

Under the attack of the four-star demon insect that was not afraid of death, and at the same time with the help of the blood-drinking knife, Zhang Yifan finally killed the eighth-level demon ape.

In the end, Zhang Yifan harvested eight demon beast corpses above level 7 and thunder attribute demon pills, as well as more than 500 four-star demon worms.

After these eight battles, the nearly 1,000 three-star demon worms have all advanced to four-star demon worms, except for those who have died.

Although Zhang Yifan can't release them all at once, at most dozens of them can be released at a time, but these demon insects are very easy to deal with a demon beast above level seven, and even against several at the same time, they can remain undefeated, which makes it very easy for Zhang Yifan to collect the corpses of demon beasts.

However, the cultivation of advanced demon insects consumes resources and becomes more and more terrifying.

In the past, in order to speed up the cultivation, Zhang Yifan was originally fed once a month to feed the elixir once a month, and the effect was very significant.

Now, if these demonic insects want to cultivate relatively quickly, they need to be fed once every five days, and they consume a lot of elixirs.

According to the amount of elixir he currently possessed, it would be exhausted in less than ten years.

And now that the four-star demon worm has shown some resistance, the effect of feeding the elixir is not as good as before.

Maybe the four-star demon worm will advance again, and the effect of feeding the elixir will be very small. Zhang Yifan knew that he needed to find a new insect and beast elixir to replace the feeding elixir.

However, the four-star demon worm has only advanced, and it is still too early to become a five-star demon worm, so there is no hurry in this matter, take your time.

Zhang Yifan had walked nearly five hundred miles at this time, and there was no road in front of him at this time, but a basin with a radius of nearly 1,000 zhang.

In the center of the basin, there is a strange stone standing alone, the stone is not big, about ten zhang in circumference, more than ten zhang high, light purple, the whole looks like a burning flame, but the flame is fixed.

What made Zhang Yifan even more pleased was that there were two thick gray vines attached to the strange stone, and the vines were faintly excited by yin thunder and lightning, which was very extraordinary, which was exactly the Xuanyin Thunder Vine he had been looking for.

These two Xuanyin Thunder Vines seemed to be thousands of years old, which was just right for him to use.

Zhang Yifan did not hesitate to intercept these two Xuanyin Thunder Vines directly, and these two Xuanyin Thunder Vines should be one zhang long after refining, which is enough for him to use.

After collecting the Xuanyin Evil Thunder Vine, Zhang Yifan set his eyes on the strange stone in front of him.

On the strange rock, he felt two completely different thunder attribute auras, which seemed to be opposite to each other and merged with each other.

The strange stone is very hard, but it is not an ore, Zhang Yifan only made a small piece with all his strength, but as soon as it is out of the strange stone, the small piece of strange stone will instantly turn into powder and dissipate in the air.

This made Zhang Yifan very curious, but after careful research, he didn't find the slightest.

The stone was just a little strange, and it didn't have any obvious effect.

"Master, I want to spend the Demon Pill Tribulation here, and I feel that this place is the most suitable for me. At this time, Zhang Yifan's voice came from Xiaobai's mind.

Zhang Yifan walked all the way and found that this place was very hidden, and the danger had been cleared by him, and Xiaobai was also safe to cross the robbery here.

"Okay, then I'll cultivate here, and when you recover, you'll spend the tribulation here. ”

Zhang Yifan began to deal with the corpses of the Thunder Demon Ape that he had collected earlier, and collected a large amount of eye spiritual blood, and he was ready to use the eye spirit blood of these mutated purple pupil Thunder Demon Ape to cultivate the Fire Eye Purple Eye Secret Technique, hoping that this secret technique would be more powerful.

Now his physical body has already met the requirements, what he lacks is the spiritual material to refine his eyes, and this time he has collected so much spiritual blood, which is enough for him to cultivate for a period of time.

Xiao Hei was injured a lot before, but after some time of recovery, although he is still unable to fight, he has been able to use the Natal Golden Flame.

Therefore, Zhang Yifan began to refine his eyes with the help of Xiao Hei's natal golden flame.

As the days passed, Zhang Yifan had been cultivating in this hidden valley for more than a month.

At this time, Zhang Yifan's eyes burst into dark purple fire eyes, and his eyes looked particularly strange and deep.

With his powerful body and fine golden flame control, Zhang Yifan consumed the eye spirit blood of the mutated Purple Pupil Thunder Demon Beast after more than a month of continuous tempering, and finally improved the Fire Eye Purple Eye Secret Technique by a large margin.

Now Zhang Yifan's fiery eyes and purple eyes can see a distance of seventy or eighty miles, and his observation of aura is more subtle, and even for some things that cannot be distinguished clearly by divine consciousness, his eyes can see more clearly.

According to the records in the secret arts, Zhang Yifan's fiery eyes and purple eyes are not far from Dacheng, and he only needs to find suitable spiritual materials to refine them before he can reach the point of Dacheng.

Dacheng's fiery eyes could see a hundred miles away, and he could even see concealment, gaining insight into the weaknesses of the formation.

This is also the highest level that can actually be achieved in the records of occult arts. As for the great supernatural powers such as penetrating the space mentioned in the secret arts, which can be thousands of miles away, it is just speculation, and no one has cultivated to such a realm.

However, Zhang Yifan estimated that when he refined his fiery eyes and purple eyes to the Dacheng realm, he should have a trace of supernatural powers. Even now, he felt that these eyes were much more reliable than their divine consciousness in this Yin Thunder Valley, where their divine consciousness was completely forbidden, and their effect was huge.

At this time, there was still half a year before Xiaobai was ready to cross the tribulation, and Zhang Yifan began to concentrate on cultivating the thunder method here.

Previously, when he was cultivating the "Nine Yin and Nine Yang Thunder True Technique", Zhang Yifan found that his cultivation speed was a little faster than usual.

This made him have to suspect that it had something to do with the stone next to him.

So he sat directly on the strange stone to cultivate, and finally confirmed this, sitting on the stone was more helpful for him to practice the exercises.

Zhang Yifan wanted to take this stone away, and tried various methods, but found that it had no effect.

Therefore, he planned to use this place as a hidden place to practice the natal exercises, and when he had time, he would come here to practice the natal exercises and enlightenment.

After cultivating the Secret Method of Fire Eyes and Purple Eyes, Zhang Yifan began to practice the Thunder Method.

The speed of cultivating the thunder method on the strange stone is very fast, and the Jiuyang Thunder Technique, which was originally thought to be jerky and difficult to understand, has made great progress at this time.

In less than two months, Zhang Yifan was able to cast three Great Yang Gang Thunder and three Great Yin Thunder, and cultivated these two thunder techniques to the first level, which can be described as a rapid progress.

And what is even more commendable is that after half a year of hard cultivation, Zhang Yifan finally cultivated the first layer of the Great Yin Yang Thunder Escape Technique, which is a life-saving escape technique.

However, the mana consumed by the Great Yin Yang Thunder Escape Technique is very terrifying, it will cost Zhang Yifan nearly one percent of his mana, and because of the reason that he has just cultivated, Zhang Yifan's body will suffer a Yin Yang Thunder counterattack every time he casts it, and his whole body becomes paralyzed and stiff in a short period of time, and he cannot immediately cast it a second time, and he must wait for his body to no longer be stiff before he can cast it.

If it is forced, it will cause a very large burden on the body, which will not only consume vitality, but also damage the body.

But even so, this technique can be called a stunt of escape, and it can quickly move nearly fifty miles in a single cast.

At this time, Xiaobai had also recovered and was ready to start welcoming the catastrophe.
