In the blink of an eye, another ten years have passed, and the years have passed only when the eyes are opened and closed.

Of course, for the enlightened monks after the foundation was built, the impact of time on their faces is almost invisible.

Therefore, the earlier the foundation was built, the younger the face looked, even if he lived to be hundreds of years old, he would only look like he was in his twenties.

Zhu Lingwu was only less than twenty-six years old when he built the foundation, so ten years later, Zhu Lingwu's appearance still looks like there has been no change.

Unless Zhu Lingwu wants to make himself older, he can use spiritual power to produce some catalysts on his skin, but how can Zhu Lingwu do such a boring thing if he is fine.

The days in the Demon Prison Tower were simple and boring, but it forced Zhu Lingwu to spend most of his time on cultivation.

Zhu Lingwu has built a good spiritual foundation where he built the foundation, so after these ten years, his cultivation realm has also directly entered the middle stage of foundation building, and at this time, Zhu Lingwu has already begun to consider constructing his own Dao foundation to prepare for the condensation of Jindan.

It is only necessary for Zhu Lingwu to observe and comprehend the natural changes of heaven and earth, so that he can understand a little bit of the natural heavenly dao rule system, so as to refer to it to construct his own Dao foundation.

This is difficult to satisfy in the Prison Demon Tower, although the bottom floor of the Prison Demon Tower where Zhu Lingwu lives now is also a special spatial enchantment, but after all, it is different from the real world outside, even if Zhu Lingwu wants to observe and perceive, he can't find a natural celestial phenomenon that can be observed and perceived.

The way of Jindan that Zhu Lingwu hoped for was a special pure yang thunder way, the way of heavenly thunder that was just to the yang.

Belch. To be precise, it should be the Pure Yang Yin Thunder Dao that Zhu Lingwu sought according to his own mutated pure yang spiritual power. It belongs to a special yin thunder of anode yin. It has the power of heavenly thunder, but it contains a special feminine power.

To put it simply, Zhu Lingwu wanted to integrate those two ancient thunder and electric runes into his spirit base, thus forming a Dao base with a composite spirit array structure.

But this kind of Dao Ji is not just a casual connection of the two Ancient Thunder, Electric Runes and Spirit Bases, it is necessary to let the Thunder Runes and Zhu Lingwu's Spirit Base perfectly fuse together to form a new Dao Base Spirit Array.

In this way, it is in line with the way of nature, and it can eventually be transformed into Zhu Lingwu's golden pill.

This requires Zhu Lingwu to observe more natural thunderstorm phenomena. According to the eruption process of natural thunder and lightning, he felt the rules of the Heavenly Dao contained in the natural thunder and lightning, and constructed the special Dao foundation conceived in Zhu Lingwu's mind according to the rules of the Heavenly Dao.

In addition, the legendary Heavenly Tribulation contains a variety of pure Yang Heavenly Thunder with complex attributes, such as what Golden Yuan Thunder, Wood Yuan Thunder, Water Yuan Thunder, Fire Yuan Thunder, Earth Yuan Thunder, even the Pure Yang Yin Thunder conceived by Zhu Lingwu in his heart, it also belongs to one of the natural Heavenly Tribulations.

If Zhu Lingwu could often see this kind of Heavenly Tribulation, maybe he would be able to quickly comprehend his Pure Yang Yin Thunder Dao, but unfortunately, the Heavenly Tribulation is something that comes at a moment's notice, how can it be so easy to see.

And now it's not a catastrophe. Even natural thunderstorms in this Demon Trap Tower are almost impossible to happen. Zhu Lingwu naturally had no way to talk about any observations and feelings.

But Zhu Lingwu can't leave the Demon Prison Tower for the time being, and it's even more impossible for Zhu Lingwu to use those soul clones outside to observe the thunderstorm celestial phenomena, and let those ghosts observe the thunder and lightning, almost letting them die.

In this way, it seems that Zhu Lingwu can't study his Pure Yang Yin Thunder Dao anymore, but after all, Zhu Lingwu is also a lich from another world, so Zhu Lingwu thought of a new way to study his Pure Yang Yin Thunder Dao.

This is also related to the special environment of the space at the bottom of the Demon Trap Tower, which was originally slowly evolving, so that Zhu Lingwu could construct artificial thunderstorms in this space according to his scientific explanation of thunder and lightning weather from the original world.

Although the thunderstorm weather constructed according to scientific principles may be different from the real thunderstorm natural world, Zhu Lingwu should also be able to study the hidden immortal path rules from it, so that he can also help him comprehend his pure yang and yin thunder dao.

Of course, to achieve this, Qiu Yangling's existence is also very important.

Qiu Yang Ling is now also regarded as the guardian mountain spirit of Fuyang Immortal Peak, and naturally he can also have a certain amount of control authority over the core Prison Demon Tower of Fuyang Immortal Peak.

Of course, this is also the permission that Zhu Lingwu and Lao Jiashan only got by bargaining, but the premise is that Wuhua Zhenren also acquiesced to Zhu Lingwu's request.

Who let Zhu Lingwu be locked up in the Demon Prison Tower and couldn't get out.

After all, this is the only way for Zhu Lingwu to comprehend the way of Jindan and seek his own Jindan Dao.

Although it is not so easy to artificially create thunderstorms, Zhu Lingwu is not a mortal after all, coupled with the help of Qiu Yang's spiritual control in the Prison Demon Tower, there was still a thunderstorm in the Prison Demon Tower.

The thunderstorm weather that had never appeared in the Prisoner Tower before could be seen every day in the Prisoner Tower, and dark clouds could often be seen gathering out of thin air in the mid-air of the Prisoner Tower, followed by thunder and lightning, and heavy rain.

In this way, Zhu Lingwu can also use this artificial thunderstorm weather every day to comprehend his pure yang and yin thunder path, which can be regarded as an accident, after all, in the natural world outside, you can't see thunderstorms every day.

At the same time, under Zhu Lingwu's nonsense, Zhu Lingwu felt that the evolution degree of the underlying space of this Demon Prisoner Tower seemed to have improved a lot, and it was a little closer to the real world in the outside world.

Maybe if this continues, it won't take a few hundred years for the spatial world of this Demon Prison Tower to completely become a real enchantment small world.

It's just that Zhu Lingwu engages in thunder and lightning in the Prison Demon Tower every day, which is really a frightening process for those aborigines in the Prison Demon Tower, that is, those demon cultivators.

Heavenly thunder is a great threat to demon cultivators, and in the normal world outside, many demon cultivators are killed by heavenly thunder.

In secular legends, bad people will always suffer retribution from the heavens, which is actually derived from these examples.

In fact, this is mainly because the heavenly thunder belongs to the power of the most yang and the strongest, and the demonic spiritual power cultivated by the demon cultivators with the magic skills often carries certain negative attributes, so under the attraction of positive and negative energy, the demon cultivators are naturally susceptible to the slashing of thunder and lightning.

Therefore, during the thunderstorm season, most demon cultivators will seek a place to retreat, hiding in caves or houses to avoid the effects of thunder and lightning on them.

But even so, the thunder that naturally occurred during the thunderstorm may still shock the demon cultivator's state of mind, which was not very stable, and make the demon cultivator's mind out of control, triggering the chance of going mad.

And now in the calm Demon Prison Tower, this kind of thunder and lightning weather often occurs, which naturally makes those demon cultivators who live in the Demon Prison Tower fearful.

Every time Zhu Lingwu engaged in thunder and lightning, these poor demon cultivators would often hide in their respective bamboo huts and secretly curse Zhu Lingwu, a damn boy.

However, apart from this matter, the demon cultivators are still more welcoming to Zhu Lingwu, a new child...... (To be continued......)
