Only a few days later, Zhang Nan got the best spirit stones sent by the master of the Phantom Beast Domain, with a total of more than 25 million, which made Zhang Nan overjoyed, with these spirit stones, there is hope that the Blood Soul Knife will be upgraded to the emperor's tool, of course, the premise is that the purple gold bowl is not too tricky.

But Zhang Nan was not in a hurry, he came to the second layer of the Tower of Babel to retreat, he told the Phantom Beast Domain Lord that they only need about thirty years, in fact, the outside thirty years, in the second layer of the Babel Tower, that is nearly three hundred years, three hundred years, for Zhang Nan, Mo said to promote the cultivation to the early stage of the Sage, even if you want to cultivate the spiritual martial arts sent by those few Phantom Beast Domain Masters to the end, that is enough.

The energy of the seventh-grade fairy spirit grass was extremely powerful, even now Zhang Nan's body was very strong, but he still didn't dare to directly devour this seventh-grade fairy spirit grass, but first took out a red flame spirit grass from the five sixth-grade fairy spirit grasses and put it directly in his mouth.

Although this red flame spirit grass has many times less energy than the seven-grade fairy spirit grass, as soon as this thing was swallowed by Zhang Nan, he immediately felt a hot feeling in his abdomen, which felt as if the flames were burning in the body, extremely hot, this is an aura containing the spiritual power of fire, so it will have such an effect, and it is the best for people with fire spirits.

However, Zhang Nan couldn't turn it off so much at the moment, and this huge energy quickly flashed away, making his forehead full of beads of sweat, desperately running the six roulettes, and then greedily absorbing it.

Soon, all these spiritual auras were pulled to all directions of the six roulette wheels, directly surrounding the six roulette wheels, forming a layer of aura shield on top of it, which looked like the earth's atmosphere, but it looked a little thin, and it also emitted a light like a fiery cloud.

This process seems simple, but it is also very difficult, you need to slowly consume that energy, and a little bit of traction.

Time flies quickly, in the blink of an eye, it is ten years, of course, this is only the time of the second layer in the Tower of Babel, only a year has passed outside, Zhang Nan has broken through to the Spirit Emperor Realm, he slowly opened his eyes, his fists were clenched fiercely, and his hands were full of sonic booms, this feeling made him feel extremely comfortable, he found that after breaking through to the Spirit Emperor Realm, the aura was at least ten times more than before, and the strength of the body was far higher than before, he now felt that if he met the Holy Son of the City of Ghost Girls he saw last time, his strength should be able to fight with the other party。

But his target this time is not just the Spirit Emperor Realm, he has always felt that his strength is not bad before, but this time when he came to the Phantom Beast Domain, he realized that his strength was not enough at all, especially the Dark Lord, even if he was seriously injured, it gave him a feeling of heart palpitations, you can imagine how terrifying it would be if it was in its heyday?

As soon as he thought of the fleeing Dark Demon Clan, he had a faint sense of crisis in his heart, so he had to improve his strength as soon as possible, there were enough resources for his cultivation, and there was a Tower of Babel that could increase ten times the time, so if he didn't work hard to improve his power, it would be unreasonable.

The one who fled back then had four Dark Lords, which made him even more uneasy, even less than there were as many Dark Lords as there were back then, but if the four Dark Lords were restored to their peak, they would still be an extremely powerful threat to the mainland, and in the past four years, those Dark Lords have still not been revealed, either they are trapped, or there is some conspiracy, if it is the former, then it is fine, if it is the latter, then it will be troublesome.

Zhang Nan is no longer alone in this world, he has too many ties, even if he can quickly break through to the Spirit Emperor and then ascend, but he can't still survive in this continent by this powerful hidden danger, otherwise his relatives and friends will face a great disaster!

Putting a six-grade fairy spirit grass into his mouth again, Zhang Nan closed his eyes again and fell into a boring cultivation.

Now that he has broken through to the early stage of the Spirit Emperor Realm, the work behind it is relatively much easier, he only needs to add the spiritual power directly to the previous atmosphere-like cover.

Time passed day by day, and Zhang Nan's strength was also increasing little by little.

In the second year, the Phantom Beast Domain Lord began to prepare for the establishment of the Sixth Sacred Domain, and she was not in a hurry at all, because now the people of the Five Great Sacred Domains were busy with the affairs of the Great War of the Ten Thousand Dynasties, and they were all waiting for the results of the Great War, and then waiting for those outstanding ones who came out of nowhere, so that they could select new disciples.

Of course, in the past two years, the Phantom Beast Domain has also begun to send people to activities outside to observe some things in the Five Sacred Domains, and the number of disciples that the Five Sacred Domains are preparing to recruit this time is obviously much more than before, the funny thing is that it seems that there has been a lot of friction between the two Sacred Domains recently, and there have been conflicts, and many people have died, which is a lot larger than before, and the number of places has also increased a lot.

As for the matter of the Five Great Sacred Domains, the Phantom Beast Domain was just a joke after dinner, and when Zhang Nan came out of retreat, they began to directly announce the establishment of the Sixth Great Sacred Domain, and when they thought of the faces of the people in the Five Great Sacred Domains at that time, the elders of the Phantom Beast Domain felt relieved.

For so many years, their five holy domains have been merry and happy outside, but they let the people of the Phantom Beast Domain stay here, and they can't leave if they want to, it seems that they have completely forgotten them, and when the time comes, they will inevitably return strongly, and the territory under their jurisdiction must be divided, even if the Phantom Beast Domain lacks nothing, then in order to relieve their anger, they should also enjoy this kind of treatment, after all, they are the biggest heroes, and they have also paid the most, this is the glory they should enjoy!

Finally, more than 20 years have passed, during this time, Xue'er's cultivation has also made a great breakthrough and reached the early stage of the Spirit Emperor Realm, but at this moment, she is a little depressed in her heart, he admires and believes in his brother incomparably, thinking that his brother is about to get out of the customs, that is, out of Zhang Nan is in the early stage of the Spirit Saint, but she is in the early stage of the Spirit Emperor Realm, which makes her a little unconvinced, and feels that her talent is too poor!

Of course, if other people knew this girl's thoughts, they would definitely hit the wall in frustration, less than thirty years later, they broke through from the early stage of the Spirit Venerable Realm to the early stage of the Spirit Emperor Realm, such a perverted breakthrough made the people of the Phantom Beast Domain depressed and about to vomit blood, I wonder if these two brothers and sisters are specially here to fight them, even if they have the best talent here, Zi Yan and Zi Xia, they have barely broken through to the peak of the early stage of the Spirit Emperor Realm at the end of the year, and they are still one step away from the middle stage of the Spirit Emperor Realm!
