The more powerful the bone demons, the higher the intelligence, and then Wang Ke encountered several bone demons, although they were all killed, but the spirit bones of these bone demons were hidden very deeply, and it was not easy to find out.

However, the bone demons encountered next were only cultivated in the Jindan period, and they did not encounter bone demons whose strength exceeded the Jindan stage, which was quite lucky.

Along the way, Wang Ke probably collected more than a dozen spirit bones of different sizes, which was also a big gain, and at the same time, in addition to harvesting these spirit bones, there were also some precious materials in the black swamp that Wang Ke had also found out.

For example, filthy stones, moonstones, and black spring water are all materials that can only be found in the black swamp, and Wang Ke unceremoniously collects these materials when he encounters them.

The most important thing is that after fighting these bone demons, Wang Ke found that the mana in his body had become more refined, and the feeling of being full of Tai made him very relaxed.

Moreover, as the time for cultivation to recover became shorter and shorter, Wang Ke found that his strength had actually improved a lot in a short period of time, and even without the Demon Transformation Secret Technique, Wang Ke's strength far surpassed that of a cultivator of the same level.

It's just that it's still too early to break through the Jindan stage, and the spiritual power in his body has not yet reached its peak, but even so, Wang Ke has plans to prepare to hit the bottleneck.

Deep in a black swamp, Wang Kepan sat in a circular space, surrounded by a transparent light shield.

In his left hand, he was playing with a five-inch-long spirit bone, and amazing spiritual power fluctuations emanated from it, this was the highest quality spirit bone that Wang Ke had harvested these days.

The fierce battle with the bone demon had consumed a lot of Wang Ke's spiritual power before, so he chose to cultivate here, but now the mana in his body has been fully recovered. Wang Ke was in no hurry to leave. but bowed his head in contemplation.

It's been a while since I came to the Black Swamp. In a short period of time, Wang Ke's strength has improved a lot, but when he thinks of the monks of the Blood River Palace, Wang Ke's heart can't help but tighten.

"I can't just rely on Julin Pavilion to ensure my safety, I must do my best to improve my strength to the Yuan Infant Stage, otherwise I won't have the strength to compete with the people of the Blood River Palace" Wang Ke thought with a solemn face.

When he was in the Great Wilderness Gate, he saw the strength of the Red Dragon, which is definitely not comparable to that of ordinary Yuan Infant Stage monks, and with his current strength, even if he adds the magic magic technique, he is definitely not the opponent of the Red Dragon. The last time I was able to escape from the Great Wilderness Gate, it was thanks to the help of Bloodflame.

With the help of the prodigal son, although he later temporarily got rid of the entanglement of the Blood River Palace, but now the prodigal son is not around, and he can only rely on Wang Ke himself.

It is not easy to ascend to the Yuan Infant Stage as much as possible, although there is a superb elixir like the Flame Pill in your hand to help impact the bottleneck, but if you have taken the Flame Pill when you break through to the Golden Pill Stage when you build the foundation, the effect of taking the Flame Pill again is definitely not as good as before, and at the same time, the bottleneck of the Yuan Infant Stage can be much more difficult than the Foundation Building Period to break through the Golden Pill Period.

Wang Ke planned that at the current cultivation speed, it would only take half a year at most to raise the mana in his body to the peak of the late stage of Jindan. When the time comes, you can be ready to hit the bottleneck of the infant stage.

With the assistance of an elixir like the Flame Pill, it is not without a glimmer of hope. However, Wang Ke definitely didn't want his hope of breaking through the Yuan Infant Stage to be only like this, with his qualifications, if the first breakthrough failed, then the second time would probably become even more difficult.

Thinking of the difficulties in his cultivation ahead, Wang Ke couldn't help frowning, and suddenly Wang Ke's heart moved, and as soon as he put away the spirit bone, the black light flashed in his right hand, and a black jade slip appeared in his hand.

This black jade slip is one of the jade slips obtained from the Ghost King Sect, although he has long had the idea of refining the weapon in his heart, but he has never done it, and Wang Ke vaguely remembers that he once read the record on this jade slip, as if there is a kind of secret technique, which can forcibly break through the bottleneck with the help of the power generated during the refining process, and the effect of this secret technique is even more powerful than some elixirs that help break through the bottleneck.

At that time, Wang Ke simply read the record of this secret technique, and was shocked by the difficulty of this secret technique, so he didn't take it to heart, but now that he thinks about it, he thinks he can study it.

The divine consciousness escaped into the jade slip, and the jade slip is all about the method and experience of refining weapons, although he doesn't know anything about refining tools, not enough Wang Ke can see that the alchemy recorded in this jade slip is definitely not ordinary.

And it took nearly ten hours for Wang Ke to find the secret art record in his impression at the end of this jade slip.

"Spiritism" This is the name of the secret technique, and when he found this secret technique, Wang Ke's eyes showed a hint of joy, but when he looked at it carefully, he couldn't help frowning.

After a few hours, Wang Ke raised his head, sighed, put the jade slip away, and fell into deep thought again, the difficulty of performing spiritism was still on his expectations.

Unexpectedly, spiritism can only be used when refining magic weapons, and ordinary spirit weapons simply cannot meet the requirements of performing spiritism.

Although Wang Ke has not yet started refining, his understanding of refining tools is no longer comparable to that of a hairy boy who has entered and exited the immortal path, and he knows very well what the magic weapon is.

The spirit weapon containing more than thirty-six formations is called a magic weapon, when he was in the Immortal Forbidden Continent, Wang Ke had never seen a magic weapon, although the difference between the best spirit weapon and the magic weapon was only one level, but it was one hundred and eight thousand miles away.

Take Wang Ke's Qiankun Ding as an example, although the Qiankun Ding is a superb spiritual weapon, containing thirty-two formations, it is too far from the real magic weapon.

Refining magic weapons requires some spiritual refining materials, this kind of material is very rare, it is very rare in the cultivation world, and if you want to use such materials to refine magic weapons, you must be a real refining master to do it, even in a place like the Five Heavens Domain, there are only a handful of refining masters who can refine magic weapons, which shows how difficult it is to refine magic weapons.

"It seems that with my strength, it is impossible to refine a magic weapon, but if you just upgrade the Qiankun Ding into a magic weapon, it is not impossible" Wang Ke instantly had a new plan.

It is very difficult to refine magic weapons, but it is relatively easy to upgrade the best spiritual weapons into magic weapons, you only need to find some precious spiritual materials, and then use these spiritual materials to upgrade the Qiankun Ding, there is a high chance that the Qiankun Ding will be upgraded into a magic weapon, and when the Qiankun Ding is upgraded to a magic weapon, you can also use spiritism.

However, things are not as simple as they seem, first of all, it is difficult to collect the spiritual materials needed to upgrade the Qiankun Ding into a magic weapon, in addition, re-refining the Qiankun Ding also requires a very clever alchemy, the spiritual materials can be collected slowly, and the improvement of the alchemy is very difficult, but fortunately, Wang Ke has not stepped into the immortal path for a long time, and the time left for him is still very long, just try to avoid the monks of the Blood River Hall and the Heavenly Spirit Sect during this time.

After thinking about it for a while, Wang Ke decided to use spiritism to help him break through to the Yuan Infant Stage, and decided to put things away after that.

Alchemy can be slowly honed, and the collection of spiritual materials must also be grasped, if you want to talk about spiritual materials, the spirit bones collected by Wang Ke are one of them, but the spiritual materials he collected at this time are slightly insufficient to upgrade the quality of Qiankun Ding, so you must find a higher quality spirit bone.

Soon after, a ray of light burst out of the swamp, spun in the air and shot out in one direction.

If you want a higher quality spirit bone, you naturally need to find a bone demon with more powerful strength, and since you were a child, you must be a bone demon in the realm of the Yuan Infant Stage, but the bone demon king with such strength is not sure that he can deal with it.

Two days later, a ray of light flew rapidly over a black swamp, followed by a dense group of bone demons, all of which were wolf-shaped, very numerous, and the aura they emitted was very powerful.

"Damn, I didn't expect to encounter so many bone demons living in groups, it's really troublesome" In the front, Wang Ke didn't encounter any group bone demons, just saw a bone demon in the late stage of Jindan on a swamp, and was about to start, but thousands of bone demons poured out of nowhere, and Wang Ke, who saw that something was wrong, turned around and fled.

A few hours later, Wang Ke landed on a black rock in the swamp, and the bone demons behind him had already retreated before they caught up with Wang Ke, and finally got rid of these bone demons, Wang Ke breathed a sigh of relief, and directly cultivated cross-legged on the rock.

At this time, the place where Wang Ke was a boundless black swamp, and there was not even a single black tree in this black swamp, only to see a large bubble coming out of the bottom of the swamp, and bursting into a burst of green smoke.

Wang Ke held a spiritual stone in each hand, and quickly absorbed the spiritual energy to restore his own cultivation, and just as Wang Ke absorbed the spiritual energy to restore his cultivation, in the depths of the black swamp next to him, two huge red light clusters suddenly flashed.

The two red clusters of light flickered and flickered a little strangely, and soon after, the surrounding swamp was still rolling, and the two red light clusters began to move.

Goo goo goo ......!

Dense bubbles emerged from the swamp, and then exploded, Wang Ke, who was cultivating with his eyes closed, suddenly opened his eyes, collected the spirit stones in his hands, stood up and turned his head to look around, frowning.

"What's going on" I saw that bubbles were bubbling all around, and the calm swamp began to roll, Wang Ke hurriedly rose into the air, suspended at a height of ten zhang, and stared down with a solemn face.

The divine consciousness poured out, and he wanted to enter the swamp to find out, but the divine consciousness had just entered the swamp when it was bounced away by a force, and it was impossible to go deep at all.

"Could it be that there are bone demons down here" Wang Ke thought with a puzzled face, but the yin qi in this place is not too strong, according to Wang Ke's guess, such a place is not very suitable for bone demon cultivation, it is precisely because of this that Wang Ke chose to cultivate here just now.

However, he didn't expect that the swamp below would suddenly change now, so Wang Ke focused his attention on the swamp below and was on guard.

The swamp below continued for about a cup of tea, and then the bubbles stopped coming out, and the swamp calmed down, but a strange feeling rose in Wang Ke's heart, as if he was being targeted.

After a while, there seemed to be no change in the swamp below, and just as Wang Ke was a little relaxed, suddenly the calm swamp fluctuated again, and a huge whirlpool appeared under Wang Ke, and the swamp within a radius of thousands of zhang was stirred. (To be continued......)
