The four of them, Nie Fan, restrained their auras, and Xiaoxiao even set up a closed-breath killing formation around them. No one could see these people here. Only those who stepped into the presence of the middle-level Yuan Emperor could sense the terrifying aura here. surge.
The black-gold force rushed into Xuanwu City, causing the entire Xuanwu City to tremble a few times. Everyone in Xuanwu City was shocked and they didn't know what was happening.
But soon everything calmed down, but the Xuan family knew that Nie Fan should be probing something, but they were all shocked when they thought of this.
Today's Nie Fan can actually shake Xuanwu City. You can imagine how terrifying Nie Fan's strength is now. Maybe he can smash this ancient city to pieces with just one slap.
"Don't pay attention to everything about him. He will definitely abide by his promises. Otherwise, he would not be able to achieve what he is today,"
After hearing his grandfather's words, Xuan Hongyu nodded slightly, but there was a strong look of determination in his eyes that he wanted to become stronger.
Rumble
At this moment, Nie Fan's true soul rushed about 300 meters underground and was blocked by a heavy breath. In front of it was a blue-black city wall, and ancient fluctuations were flowing on the green-black city wall. This made Nie Fan suddenly panic. happiness.
It seems that there is indeed a terrible restriction under the foundation of the city wall. Three hundred meters is still the foundation of the city wall. This huge project can imagine how huge it was originally.
Continuing to sink, after 500 meters, Nie Fan's true soul passed directly through the underground soil and then rushed upward quickly. Under the foundation of the city wall at a depth of 350 meters, patches of blue-black light were flowing, and there were The Xuanwu mark is circulating.
"Xuanwu Formation," Fan looked at the cyan light mask with the Xuanwu mark in surprise.
"How strong was Xuanwu back then?" Nie Fan said doubtfully to the Dragon Sword Soul.
Dragon Sword Soul shook his head helplessly and said: "I don't know, but the four saints all have their own terrible methods. It's really impossible to judge who is stronger and who is weaker. Maybe we can know if they fight. ,"
Nie Fan nodded slightly. From the words of the Soul of the Dragon Sword, he knew that the strength of the Xuanwu Saint was absolutely terrifying. Thinking of it, he was also a terrifying existence that had stepped into the pseudo-god realm.
Why were the four imperial cities built back then? Was it for the four saints to live there, to hide terrible secrets, or to leave behind their own traditions and heritage.
Nie Fan could not know the reason at this time, but Nie Fan knew that the Xuanwu formation below was definitely not easy to break.
"Try it and see. Maybe it does contain a trace of Xuanwu origin," the Soul of Dragon Island smiled at Nie Fan.
Nie Fan looked at the Dragon Blade Soul and said doubtfully, "You seem to be more anxious than me."
"I just want to find the master's aura from the Xuanwu aura," Dragon Sword Soul explained.
Nie Fan no longer paid attention to this guy. Nie Fan always felt that after a hundred years, the soul of the dragon sword had undergone a terrible transformation. As for how powerful it was, Nie Fan could not estimate it. After all, it was a weapon of a saint. It was definitely a weapon that shocked everyone. The terrifying existence of heaven.
The true soul rushed towards the Xuanwu Formation quickly, but as soon as it touched the Xuanwu Formation, Nie Fan's true soul power quickly disintegrated. The Xuanwu Formation contained a terrifying and heavy aura that seemed to be suppressed. This is like killing all the worlds.
"Try your space world,"
Dragon Blade Soul reminded.
Nie Fan nodded slightly. The space world contained the completed Xuanwu mark, but there was no trace of Xuanwu origin. If he could get a trace of Xuanwu origin, Nie Fan's space world could evolve rapidly and improve rapidly.
As soon as the space world emerged, a terrifying coercion enveloped Xuanwu City. At this moment, Xuanwu City trembled again. The slight tremor was still felt by many people.
At this moment, Nie Fan's body did not stay outside but rushed into the Xuanwu City. Breaking through the soil, Nie Fan's body quickly rushed towards the front of the Xuanwu Formation.
At this moment, Nie Fan's space world manifested rapidly, and then one after another Xuanwu marks slowly poured out, carrying the terrifying world energy and instantly blasted towards the Xuanwu formation.
Puchi
A slight noise made Nie Fan slightly startled. The energy of the space world carrying the Xuanwu mark rushed into the Xuanwu formation very easily.
In an instant, Nie Fan was extremely pleasantly surprised, but as the saying goes, extreme happiness brings sorrow and sweetness, and bitterness arises. The Xuanwu formation that was easily entered instantly rioted, and a terrifying surge of power instantly exploded Nie Fan's space world energy.
This scene made Nie Fan's expression change, and blood flowed from the corner of Nie Fan's mouth at this moment. The energy of the space world and the power of the true soul were crushed by the Xuanwu formation at this moment.
"Don't enter it so easily. Xuanwu looks very honest but that guy is very cunning, so you must be careful," the Dragon Sword Soul reminded him when he saw Nie Fan injured.
"Why didn't you tell me earlier?" Nie Fan said a little unhappy.
"Who knew you were so careless," Dragon Blade Soul retorted.
Nie Fan glared at the Dragon Blade Soul and then wiped the blood from the corner of his mouth. At this moment, Nie Fan's eyes had a solemn look. The next moment, Nie Fan's space world appeared again, and then slowly began. Penetrate the Xuanwu Formation.
Time passed slowly, and one day later, one-third of the inner world was actually integrated into the Xuanwu formation. At this moment, Nie Fan's energy and spirit were raised to the peak. If something unexpected happened, Nie Fan's inner world would be completely destroyed. It might be crushed by this terrifying Xuanwu formation.
Once the space world explodes, Nie Fan will be seriously injured even if he doesn't die.
Therefore, Nie Fan who is so bold now is playing with fire. It is very likely that he will end up playing with fire and burning himself. However, Nie Fan has experienced too many life and death experiences along the way.
Wealth and honor are sought in danger. If you don't enter the tiger's den, you won't get the tiger's cub. Some things require courage to fight for it. If Nie Fan succeeds this time, he will definitely get unparalleled benefits.
Nie Fan knew that if the Xuanwu Formation did not contain the Xuanwu Origin, it would never be able to possess such terrifying power. Nie Fan believed that the Xuanwu Formation contained the terrifying Xuanwu Origin.
"Be careful," Dragon Blade Soul was shocked when he saw Nie Fan being so bold. He didn't expect Nie Fan to be so decisive. If Nie Fan had crippled him for the rest of his life, it would be very difficult for him to recover.
Nie Fan did not speak, but his forehead was covered with fine sweat. As long as the space world is completely integrated into the Xuanwu Formation and intact, Nie Fan can use the Immortal Magic Book to refine the Xuanwu Formation. In the end, Nie Fan can Obtaining the origin of Xuanwu will make your space world more terrifying, and you can even obtain this terrifying Xuanwu Formation.
Time has passed in a hurry. This month, the three of them have been guarding Xuanwu City solemnly. They know that Nie Fan must have discovered something below at this time, otherwise it would not have been possible for him to stay below for more than a month. time.
"Protect yourself well and don't hurt innocent people," Xiaoxiao said in a deep voice.
The big man and Feng Wuxing both nodded slightly.
Another month has passed. After this day, Nie Fan's expression became extremely solemn. At this moment, Nie Fan saw that he still had less than one-tenth of the space world left. He was a little excited but suppressed it.
There was a deep light shining in his solemn eyes.
One day four months later, Nie Fan's eyes suddenly showed a hint of joy. At this moment, Nie Fan's space world was completely integrated into the Xuanwu Formation.
