A day later, Zhang Feng returned, but his strength was improved by I don't know how many times than before, not only did Dabai and Mirage break through, but after the breakthrough of the two, there was also a chain reaction.

Zhang Feng's deity, the Alien Fire Vermilion Bird, were all stained with light, and they made breakthroughs one after another, and successfully advanced to the cave sky.

At the time of the breakthrough, various visions appeared, and there was even more than one Heavenly Tribulation, but Zhang Feng's combat power was strong, and with the help of the Demon God and the World Tree, he easily survived, and he also absorbed the power of the Thunder Tribulation, which greatly improved his cultivation.

For example, Zhang Feng's own deity, at this moment, the cultivation progress on the panel has reached the first 7% of the Cave Heaven Realm.

In addition to the increase in combat power, Zhang Feng's longevity has also increased greatly, and the life level has further undergone an essential leap.

After returning to the cave in a low-key manner, Zhang Feng immediately upgraded the equipment on his body, combined with the fusion technique and formation, as well as the various refining materials that had been equipped for a long time, and officially upgraded them to the Yu level.

The improvement of equipment also made Zhang Feng's combat power more powerful.

Then, Zhang Feng went to the Gods and Demons Fantasy Realm again, and carried out an anonymous challenge, and found that the monsters that appeared in this pass were all extremely powerful, but with his improvement, the breakthrough was still extremely simple, and under the full explosion, he passed five levels in one breath one after another, and each time he easily passed with only one shot.

However, with the improvement of his realm, the God and Demon Illusion Realm provided more and more energy, but the improvement of cultivation became smaller than before, because the higher the realm, the more difficult and slow it was to improve, not to mention that he was still the power of the Heavenly Cave Heaven.

After reaching the fifth level, his cultivation had only increased to 38% of the first level.

Fortunately, Zhang Feng was not disappointed, this range was actually good, enough to save him a lot of resources and time.

What's more, Zhang Feng also got an additional reward again, a golden treasure chest, and after opening it, he unexpectedly got a refining blueprint, whose content is profound and mysterious, and it is the refining blueprint of the best god and demon suit.

Zhang Feng had expected it and was still overjoyed.

Previously, the high-level god and demon suit can be said to have made great contributions to him, and it has played a great role in battles many times, especially its terrifying improvement effect on attack and defense, which even the World Tree and the Immortal Golden Body cannot replace.

If the premium is so powerful, what about the best? It's exciting to think about.

According to the records in the drawings, once the best god and demon set is successfully refined, a single piece is the best in the universe, and a set is even more celestial-level.

The Zeo level also corresponds to the level of the legendary Zepe Light Realm above the Cave Heaven, but ordinary Zeal-level equipment, the Cave Heaven Realm cannot be obtained at all, and it cannot be used, but the best god and demon suit does not have this deficiency at all, even if the Cave Heaven can be used, its quality and power are even among the best in the Celestial Level.

After five levels, Zhang Feng continued to break through the level, and even the last level was a little difficult, but he still quickly passed the five levels again, and at the same time, his cultivation progress also successfully reached 115% of the first weight of the cave.

This increase is simply outrageously small, and it can't be compared with the rapid improvement in the past.

Fortunately, it was finally improved to one level, and as long as Zhang Feng was willing, he could break through to the cave heaven double at any time.

Zhang Feng had already been mentally prepared, and he was not too disappointed, and he was even quite happy, it was better to be able to improve quickly than to cultivate slowly.

After this tenth level, the golden treasure chest also appeared again, and as soon as Zhang Feng opened it, he immediately entered the inheritance space of the God and Demon Martial Dao Monument again.

This time, the space and the gods and demons martial arts monument are huge and strong I don't know how many times stronger than before, among them, the aura of heaven and earth is incomparably abundant, beyond imagination, and even the aura of heaven and earth contains the way of heaven that can be comprehended.

Not to mention the gods and demons martial arts stele, what is contained in the stone stele this time is the martial arts inheritance of the Dongtian realm.

Moreover, when Zhang Feng's fingers touched the Divine and Demon Martial Arts Monument, he immediately got the relevant information and found that this retreat lasted for a full five hundred years.

Fortunately, five hundred years have passed here, and the outside is still only a moment in the past, otherwise Zhang Feng would go out after five hundred years, I am afraid that the outside will already be a matter of people.

In addition, it does not consume longevity here, does not increase the age of body and soul, and Zhang Feng does not have to worry, he has been cultivating here for five hundred years, and if he goes out, he will not meet the selection criteria of the Demon Palace.

Rumble!

Zhang Feng's mind moved first, and a divine light immediately rose to the sky, illuminating the entire God and Demon Martial Dao space, and his cultivation instantly rose to the second level of the Cave Heaven Realm.

After finishing his cultivation, Zhang Feng took out the Night Pearl, illuminated the space, and then released the mirage, Dabai and other existences, and began to comprehend the gods and demons martial arts monument with him.

However, this time, although Zhang Feng knew that he would definitely be able to enter the Divine and Demon Martial Dao space again, he did not bring his parents and others in, because the Divine and Demon Martial Dao Stone Tablet here was too mysterious, and the aura emitted alone would cause great damage to them who were not enough to cultivate.

Even, even the aura of heaven and earth here is too strong for them, and it is not a good thing that they will be swept away.

Also, the last two hundred years were fine, but this time there are five hundred years, even if you can accompany each other here, and even if you go to the mountains and rivers map, it is a bit long and boring, it is better to wait outside, only for a moment.

Anyway, Zhang Feng is very strong now, and he will be even stronger in the future, he can completely protect them, and they don't need to work hard to cultivate.

During the penance, time passed very quickly, and five hundred years passed in a blink of an eye, during which both Zhang Feng and the demon gods benefited a lot, and they received many inheritances from the gods and demons martial arts monuments.

At the same time, their cultivation is higher, and their martial arts, secret arts, etc., are also more powerful, and they have even created a lot of secret arts and martial arts.

Among them, the mirage, the Great White, the Demon God, and the Alien Fire Vermilion Bird have all been successfully promoted to the sixth level of the Cave Heaven, and even the Horned Demon Emperor has broken through to the first level of the Cave Heaven, and Zhang Feng himself has made a small progress, but it has also reached the triple 88%.

Of course, this is also thanks to the fact that he himself carries a large amount of supplies, as well as the World Tree and the Willing Power to help.

Otherwise, with his Heavenly Grade Cave Heaven power and powerful attributes, even if it is five hundred years, he may not be able to improve by one level.

However, the ascension is slower than that of other martial artists, and the combat power brought by the ascension is also greater, far from being comparable to Liu Qingyu and others.

Of course, according to Zhang Feng's speculation, Liu Qingyu and his ilk were able to reach the realm of Dongtian at a young age, and it was obviously inseparable from the support of their family, which could not be compared even if Zhang Feng was now the first in the central region.

At the same time, Liu Qingyu and others must have had a great opportunity.

What's more, in the past five hundred years, Zhang Feng has finally deduced the cosmic marksmanship into the follow-up quadruple, and has already used 4 free points to fill it, and now the trick of this marksmanship is still the Big Bang, but it is much stronger than before, and its quality has already reached the peak of the universe!

Even, this is almost Zhang Feng's biggest harvest in the past five hundred years!

"It's a pity, with my current cultivation, if I want to break through ten times in a row again, it shouldn't be enough, but fortunately, if I pass the selection within the East China Sea, there should be no problem, so I'll wait until I come back to break through later!"

On this day, at the end of five hundred years, Zhang Feng returned to the illusion field, thought for a moment, and decisively stepped into the void turbulence around the illusion.
