The dark attribute of the Dark Flame is inherently the opposite of the pure light element!

As soon as they came together, the Stygian Flame and the Light Elemental experienced a violent annihilation and explosion. Although the light elemental energy on the light warrior's body seemed to be more, Lu Chengfeng's flame was like a bone appendage, and it kept burning when it was touched, as if it could not be extinguished. As the Stygian Flame shot past one after another, the light on the Light Warrior's body began to dim rapidly.

In just five or six seconds, its body, hidden in the light, gradually revealed.

In terms of strength, this guy is also very strong. It's a pity that in the face of the evil god's flames, the resistance of the light warriors pales too pale. If it weren't for the fact that it belonged to some kind of puppet like the Heavenly Destroyer, and there was no pain, it would have screamed a long time ago.

Another dense rain of arrows!

Under Lu Chengfeng's control, the black light feathers shot down from the volley exhausted all the power overflowing from the light warriors. Then, the Stygian Flame wings behind him peeled off from his body, and once again transformed into a black Skeleton Giant Blade. Due to the compression of the flames, the color of the Skeleton Qi Blade from the back of the blade to the blade appeared in black, purple, blue, and white. Compared to the previous Stygian Flame attack, the final Skeleton Qi's Blade was at least ten times more powerful.

The final liberation of the three knives is reappeared!

Although it hasn't been long since the last use, Lu Chengfeng's strength has already improved again. Compared to the reluctance to deal with the puppeteer's sword, this time the Skeleton Qi's Blade can already be controlled at will. In the fear of the warriors of light, against the backdrop of the gradient light of black, purple, blue, and white, the two giant blades of the skeleton qi converged, and the killing machine was awe-inspiring!

Even though this Qi Liberated by the Flame did not lock on to the Liu family sisters, it was only affected, which already made the two of them feel breathless.

The light warrior who was locked on the front also knew the moment of life and death, and it sparked all the remaining strength, forming a ring of light shield in front of him, trying to block this mortal blow.

"Break it for me!"

Lu Chengfeng let out a loud shout, causing the raging black flame to burn ten times as fiercely, and hit the first knife in the air!

Even at this point, the burning black flame was still extremely quiet, and there was no sound. On the contrary, when the Liberation Three Swords broke through the air, the air near the blades made a boiling sound. With an unprecedentedly violent explosion and annihilation, the ring light shield in front of the light warrior was shattered with a single blow!

At this moment, the Warrior of Light finally felt the danger of being destroyed.

Although the rich light energy had disappeared, it resolutely chose to completely let go of the talisman on its body and make a last stand. As the runes of the Cloud Realm lit up one after another on its body, it used its own body as a carrier point, condensing an unprecedented ball of light, ready to fight with Lu Chengfeng. However, this was enough to be comparable to the light ball of the eighth-order powerhouse's full force, and it was also completely annihilated in front of the second sword of liberation!

Of course, Lu Chengfeng, who blocked this blow, was also uncomfortable.

Even with the protection of the remaining Stygian Flame power, the huge shock wave and anti-shock force still made him almost vomit blood. But Lu Chengfeng knew very well in his heart that it was already the last resistance of the light warriors!

After a brief moment of accumulation, he injected all the remaining black flames into the final sword. At that moment, he had the feeling that even the nearby space was affected and entered a temporary state of instability. In the face of such power, the light warriors who tried to escape found that their bodies were completely uncontrollable and could not move. Then, the black brilliance fell to the end, cutting this monster that made Lan Fengyue have to retreat into two pieces!

After the turbulent air waves dissipated, Lu Chengfeng slowly stepped on the ground with his remaining strength.

The resurrection precursor that Lan Fengyue said did not appear, and the battle ended in fifteen seconds!

Although the powerful power just now did not belong to him at all, seeing the two armor puppets that fell under his feet, as well as the shock of the Liu family sisters, Lu Chengfeng couldn't help but feel a sense of satisfaction in his heart. In addition to being grateful to his ancestors for leaving such a means of protection, he also looked forward more and more that it would not be long before his own strength could reach such a level!

"Brother Lu is really getting more and more powerful. ”

Liu Yuhan praised him from the bottom of his heart, stepped forward, and helped him clean up the battlefield. In fact, there is nothing to do, just collect the armor fragments that were scattered by the Stygian Flame Liberation and recollect them. Although he was once attacked by the power of the Underworld, after this guy died, Lu Chengfeng took the initiative to disperse the attached flames, allowing most of the light warrior's body to survive.

Without the light outside, he had already recognized the material contained in it, which could gather and contain light energy—light elemental powder!

This is a very rare and precious material, which is produced on the Ink Wind Continent, but the production is very small. In contrast, the cloud realm attached to the continent is easier to see. Lu Chengfeng only needed to bring back the fragments of these armor puppets and hand them over to the top craftsmen, from which the elemental powder could be extracted again.

At that time, the lightsaber forged based on it will be at least a six-grade, and the performance will be very superior!

"Where next?"

Seeing Lu Chengfeng get up again, Liu Yubing threw him an inquiring look.

"Let's delay here for a while, I guess Sean and they have already done the destroyer of the sky. In that case, let's move on. It's a rare trip to get in, and I'm going to the top of the Sky City!"

This is one of the goals that Lu Chengfeng set before he came in.

The sisters of the Liu family have an indifferent mentality, and the reason why the two of them came in is nothing more than to represent the Liu family and perform the supervision tasks required by the Mage Guild. This task, after passing through the Golden Stone Gate and Sean's request to explore in groups, can actually be completed. Even if the three of them go back now, the Mage Guild won't say anything. Hearing Lu Chengfeng say this, the sisters of the Liu family naturally had no objection.

So, the three of them began to turn back and explore again.

When they returned to the space of the Heavenly Destroyer, sure enough, Sean and Lan Fengyue had already gone to the empty building. The tray of condensed magic water in the middle was also looted, and not a drop was left. Without these things that contained the source of energy, although the magic in the surrounding space was still strong, the three of them could feel that it had begun to escape little by little. It may not take a few days to get back to normal.

Next to this tray is the defeated Celestial Destroyer.

Since he didn't watch the last battle, Lu Chengfeng didn't know what kind of blow this guy had suffered. But the intensity of the attack was evident from its tattered armor and the remains of its lightsaber that were cut in half, with only the hilt remaining. At the first few glances, Lu Chengfeng was still a little surprised, Sean and Lan Fengyue actually didn't touch the wreckage of the lightsaber, but it didn't take long for him to understand that the two of them didn't know the value of the wreckage of the lightsaber at all!

If it was a greatsword of the same grade, they might recover the remains and forge it again after breaking it. However, the construction of the lightsaber is completely different from that of the greatsword. Its sword body was only supported by a very short and thin sword core, and all that was left to spread out was the light energy excited by the lightsaber circuit. Once destroyed, the blade shatters completely, leaving only a bare, inconspicuous hilt.

In the eyes of those who do not know how to do it, such a sword hilt is worthless.

However, as the person in the world who knows the structure of the lightsaber best, Lu Chengfeng knows that the essence of this sword is still there. Because, the hilt of its sword is almost intact, and the elemental gems that are set in it and can store energy have not been broken. Remember the three elements of a lightsaber: a gem/core that stores energy and withstands the impact of enemies, a stable circuit design that excites light energy, and a material that gathers and carries light energy!

With these three main parts, the preparation for casting a lightsaber is eighty percent complete.

The rest is nothing more than to make up some materials and specific processes.

When Lu Chengfeng forged the Blue Shadow Thunder Light Sword, the gem he used was the magic core of the mutated thunder beast. Although it was a very good choice at the time, it was much worse compared to this Heavenly Destroyer's lightsaber core. As for the materials that gather light energy, Lu Chengfeng used the bone powder of the fluorescent cat demon at the beginning, which was only the material of the third-order demonic beast. But this time, it came from a warrior of light with eighth-order strength, and for this reason, he even used the Flame Orb!

One is the material on the third-order demonic beast, and the other is taken from the eighth-order puppet, and the gap between them is even more worlds apart!

As for the third point of the excitation loop, it is the least worrying thing for Lu Chengfeng. He is familiar with so many classic lightsaber designs of the Lu family. The design circuit of the Biying Thunder Light Sword is just one of the Lu family's early riser styles. As long as he wants, he can always come up with a better design circuit.

This time I went back, and it seemed that a new lightsaber would not be able to run away!

After such a small anticipation, Lu Chengfeng threw the hilt of the knight's lightsaber into the storage ring. It's just that as soon as he thought of the price of asking Xinda to start work, Lu Chengfeng couldn't help but complain again - he wanted at least 100,000 gold!

That old guy, the strength is indeed not enough, but it's a pity that he is greedy for money and lustful.

Anyway, after accidentally gathering the two major materials for the new lightsaber, Lu Chengfeng and the Liu family sisters began to follow the traces and continue to move forward. After reuniting, Sean was obviously not thrown away by Lan Fengyue again. The two groups merged back together, each with their own mind to continue to climb up.

Since they needed to fight, it only took Lu Chengfeng and the Liu sisters half a day to catch up with their tails. It's just that Lu Chengfeng was very unhappy because the magic water was robbed, and he didn't bother to step forward, so he stayed far behind the Liu family sisters. In this way, not only will the two sides be saved when they meet again, but they can also save more effort.

In such a long and boring advance, the three of them gradually ascended to more than two hundred and eighty floors. At this point, even people with a poor sense of space can feel that the space inside the tower is getting smaller and smaller. A more sensitive one like Lu Chengfeng can even calculate that the area here is only about one-third of the bottom layer. What this means, it is clear to anyone - after a few days of fighting, they are about to reach the very top of Sky City! Is there really a portal to the Realm in the Clouds?
