After Xia Fan left Hanjing City for thousands of miles, the five colorful crystal ponds behind him instantly emitted colorful light. Surrounded by the seven-colored light, the Rainbow Sword burst out with three meters of rainbow light in the sky.

The Hongmang Sword emitted a trembling sound, which was driven to the limit, because the spiritual energy absorbed by Xia Fan's five colorful crystal pools had reached a terrifying level.

If Xia Fan completes this perfect foundation building for the first time, the dialogue with the small picture when casting this colorful crystal pool is that a general stone pool is like a motor on a motorcycle, a silver spirit pool is like an engine of a general car, and a golden spirit pool is a sports car engine. As for the normally perfect crystal pool, it is like an engine on a racing car.

But because of physical reasons, there is no way to practice and cannot possess these gradually. Xia Fan simply crossed all of this and installed the engine that should belong to the plane on his body.

At that time, Xia Fan used this metaphor when he was on Earth in his first life because Xiaotutu did not understand these aspects, and because he was the spirit of the Immortal Sutra Pavilion, he was extremely confident that he knew everything in heaven and earth.

In fact, after rebirth, Xia Fan really practiced the perfect seven-color crystal pool to the fifth seat, and was completely activated, which was really terrifying. Of course, this also has a flaw, because it was too huge to transform magic power into the body, which was generally unbearable. Therefore, when Xia Fan chose the most stable technique, it was because of this. After breaking through the fairy world, he learned the Rejuvenation Chapter from Xiaotutu, because it was also because urging this seven-color crystal pool brought huge power, and it also brought huge load to the body.

Therefore, when Xia Fan practices, fights, and activates the power of the spirit pool to activate the power, he will continue to harm himself. He has the chapter on Rejuvenation and pills to make up for it, and his body continues to recover quickly after subtle damage. This also leads to Xia Fan's physical strength exceeding his own strength. Only in this way can he bear his increasingly huge power.

Before, he had just flew with his sword in an ordinary stone pool, which had exceeded the ninth level of ordinary foundation building. Now Xia Fan let go with all his might, ignoring the load and damage of his body. The power absorbed by the colorful crystal pool pushed the Hongmang Sword, and the speed was comparable to that of the average spiritual cultivation stage. Therefore, for Xia Fan, body tempering is anytime and anywhere. At this moment, when flying at full speed, he had to continuously recover his damaged body and allow his body to complete tempering again and again.

After tens of thousands of miles, even though Xia Fan was not afraid of exhaustion with the terrifying colorful crystal pool, he flew at full speed without stopping, and had to arrive for three days and three nights.

Although it took a long time, this was also because Xia Fan deliberately avoided the city and also deliberately flew high altitudes. In addition, he had all his strength to activate the colorful crystal pool, which was also a special practice for Xia Fan.

However, even though there was no problem with the continuous supply of spiritual energy in the seven-color crystal pool, Xia Fan felt a little tired mentally, so when he fell far away around the Burning Demon City, Xia Fan's first thing was to take a break, cushion, and even directly cast a small formation and lay there for a sleep. Then he took out the things, ate some food, and took several hours to restore his mental state to the best, and then entered the scope of the Burning Demon City.

Hundreds of miles around the Burning Demon City have become a forbidden area. This forbidden area is not mandatory, but no one is willing to come here. Ordinary people have no way to get close to it. This place is scorched earth, extremely hot. Xia Fan just walked in dozens of miles and felt that the temperature inside was at least close to ten degrees, which forced him to activate his magic power to block it.

Even the cultivators were not willing to come here, and even spiritual energy could not be condensed in the sky around them. But I think the last battle here was so tragic. According to records, after the Demon Kingdom massacred the city, His Majesty personally ordered the killing of everything, and finally the entire city was completely burned in a war.

Step by step, the temperature kept rising.

"There is not even a corpse. This fire is not like a flame of fighting. Judging from the position and heat, how does it look like the effect of the extreme fire formation?" But the more he walked in, the more he felt something was wrong and others could not notice it, but Xia Fan's attainment in the formation made him quickly realize it.

Obviously, the situation in the Burning Demon City is not consistent with the official statement, but this doesn't matter to Xia Fan. He just felt a little curious because with his current strength, he just entered the central area of ​​the Burning Demon City normally and felt that he couldn't breathe and sweat.

The situation here is so bad that even the Soul-raising period is difficult to support for a long time, let alone the ruins here, and no one is willing to come here.

More than ten years have passed, and it is still the case here. Xia Fan couldn't help but guess secretly. But that was just a thought. Then Xia Fan raised his hand and instantly sacrificed the Ten Thousand Soul Banner.

"Ice Formation, swoosh..." Xia Fan controlled the residual souls in the Ten Thousand Soul Banner and instantly arranged an ice formation around him. As the formation was formed, the surrounding temperature dropped sharply. Xia Fan, who was almost unable to support it, breathed a long sigh.

After a while, Xia Fan felt that it was harder than flying for three days and three nights in a row. Moreover, the spiritual energy around him was in chaos and could not be absorbed. Xia Fan had to take two spiritual energy pills to restore the spiritual energy.

Half an hour later, Xia Fan felt the residual soul in the Ten Thousand Soul Banner trembling. He knew that he could not stay here for a long time. When he raised his hand, he instantly distributed around him. However, this time Xia Fan only needed a drop of blood to pop out. With the help of the Ten Thousand Soul Banner that had been refined, he instantly triggered these ninety-ninety-one meteorite iron steel pillars.

"Buzz...boom..." Ninety-nine eighty-one meteorite steel pillars trembled instantly, and the formation was activated, but even Xia Fan did not expect that countless residual souls were instantly stimulated like last time in the Chaos Soul Flood. Because according to what he understood at that time, in addition to the many demon cultivators in the demon kingdom, many powerful people summoned from the demon world and hundreds of thousands of Han dynasty troops were buried here.

With millions of civilians, even if most of them are destroyed by this extreme fire formation, the residual souls here should be much stronger and more powerful than the Chaos Soul Flood.

But what Xia Fan had never expected was that under the urge of his formation, only dozens of residual souls emerged, and they were extremely weak, without hostility or murderous aura. Except for a few residual souls that appeared in the ice formation formed within dozens of meters surrounding Xia Fan's ten thousand souls, as soon as the other residual souls emerged, they were completely killed by the scorching temperature, and were clean and dissipated between heaven and earth.

"Damn it!!" This situation immediately surprised Xia Fan, but at the same time, he was a little excited. It was abnormal that something was wrong!

The ground here was burned for dozens of meters and was even more scorching. I'm afraid even the spiritual consciousness in the God Transformation Stage would be difficult to detect the situation. However, Xia Fan had his own way. He condensed the seal technique with his hands and instantly gathered the range of the Ten Thousand Soul Banner Ice Array. Let more residual souls be driven and controlled by him, and then controlled the residual souls in the Ten Thousand Soul Banner and directly scattered onto the eighty-one meteorite iron pillars.

"Buzz buzz..." Xia Fan's residual souls surrounding each of the meteorite steel pillars condensed the formation, and in an instant the meteorite steel pillars all penetrated deep into the ground. The scorching temperature made the meteorite steel pillars melt. Fortunately, Xia Fan formed a formation on the meteorite steel pillars with his residual soul, which prevented these meteorite steel pillars from being melted.

"Bang bang bang..." Finally, eighty-one meteorite steel pillars penetrated the scorched earth layer, and then they felt the temperature drop sharply. Xia Fan instantly felt the situation below with the help of the residual soul in the meteorite steel pillar.

"Roar...ah..."

"Kill... Kill..."

“Woo…”

………

Countless remnants formed square formations and were bound there. The feeling was very similar to Xia Fan controlling the remnants of the Ten Thousand Soul Banner. However, Xia Fan completely tempered the control, and used a series of forces to restrain it. The spontaneous power of these remnants supported the outer circle to block their power and continuously operated. Then, a natural shielding extreme fire formation was formed here, which also had a hidden effect.

If it weren't for the high temperature blocking caused by the Extreme Fire Formation, it wouldn't be difficult to detect the situation below with Xia Fan's formation attainment. If he hadn't happened to collect the residual soul this time, he wouldn't have deliberately investigated it, and he would never have found that there was such a thing inside.

"Damn, there is something wrong." Xia Fan was not afraid of rejoicing, and his eyes lit up. Then he immediately controlled the power of the Ten Thousand Soul Banner, controlled the residual souls in the meteorite steel pillar, and directly broke the residual souls that were blocked by these formations. The residual souls here are of high quality, several times higher than those of the Chaos Soul Flood. The residual souls that can survive in this situation must be of extraordinary quality.

However, when Xia Fan broke the formation and the hidden effect disappeared, he instantly felt a surge of demonic energy surging from the depths of hundreds of meters underground. This demonic energy was extremely amazing. This demonic energy was much stronger than ordinary monsters. With the help of the residual soul on the meteorite steel pillar, he rushed down instantly and saw a huge head of a hundred meters below, and his body seemed to extend downward.

Not only that, at this moment, after the hidden formation disappeared, Xia Fan realized that there were actually a force similar to this one around him. This was not the most critical. The most critical thing was that Xia Fan felt that this guy was actually alive. Its aura seemed to be recovering, and he noticed that there was external force, and his eyes seemed to move for a moment.

Damn it!

At this moment, when these remnants of souls came out, they immediately became almost crazy. However, Xia Fan did not give them this opportunity and once again activated the meteorite iron steel pillar to force these remnants of souls. Then there was a scream. Because of the high temperature of the scorched earth in the outer layer, many of the forced remnants of souls disappeared directly. Even the stronger ones immediately became much more depressed after they came out, which helped Xia Fan a lot of them.

Xia Fan was sure of that guy's aura. If Su Xing really wanted to kill him instantly, but if Xia Fan really left like this, it was not his personality. Even though he knew that the demon world was in danger, he would not forget to get benefits even under that situation. Although he realized that the situation was strange and not good, he finally felt a sank in the end, and asked for wealth and honor, and first accomplish the purpose of this trip and then say it.

Thinking of this, Xia Fan was faster and began to refine the Ten Thousand Souls Banner again skillfully. Now Xia Fan's power is much stronger than when he refined the first Ten Thousand Souls Banner last time, not to mention that the single-horned black bull demon core he used now is much stronger than the head of the three-headed monster bird. In addition, the remnant souls here did not resist too much. Xia Fan spent less than an hour and a half, and was worried and distracted. He carefully paid attention to whether the huge demon dragon would wake up.

The first thing Xia Fan did after refining the Ten Thousand Souls Banner was to urge the residual souls in the Ten Thousand Souls Banner to rush into the lower part again and thoroughly investigate the situation below.

"I...Damn..." Xia Fan couldn't help but take a breath of air conditioning during this investigation.

In nine directions, nine groups of the same remnant souls were gathered. Before Xia Fan broke one, there were eight formations and remnant souls left. Xia Fan knew what was going on without breaking them all at this moment.
Chapter completed!
