Sun saw the fires and smoke on God's Tech City and his countenance turned cold. He wants to kill the fallens inside the city as Anna was there but if he stopped killing the flying fallens more enemies will attack inside the city. That will endanger Anna's life even more. But there are ten peak Knight Rank Mystics with Anna as bodyguards, he was sure that they will protect her no matter what the cost

The fallens' attack become even more ferocious and they don't care how many of them were getting killed. However, the humans are different, their morale was slowly going down as they thought the fallens are endless. What they didn't know was the number of fallens are continuing to dwindle down at a rapid rate

"[Hell Flame Magic: Hell Flame Shower!]" Hundreds of small black burning flames descended down from the sky and burned down a lot of fallens into ashes. However, the fallens he killed were just like a drop in the ocean

The fallens' non-stop assault caused the human army to suffer a lot of losses. This was something that Sun cannot accept. Sun's face darkened and black lines spread from the word 'envy' on his forehead

His aura rose and an oppressive atmosphere reverberated in the whole battlefield. His body glowed with a black light that devoured light itself. The dark aura around him just made his already devilish look to become even more devilish

He's already at the peak of Grand Knight Rank yet his strength still soared so high that only special beings has the strenght similar to him in the same level. Even then, his strength was still far from Rank 4 Supernaturals. If the Mother Fallen can use its full strenght, the fallen can easily kill Sun without any effort at all

The strenght of Sun's Lance also increased as it 'ate' more envy energy. The flames on it burned even more furiously. "DIE!!" Sun shouted and waved his Lance horizontally and an arc of black flame cut down the fallens on its way as easily as cutting a grass

Cutting fallens in half was not enough to kill them but the flames left on their body burned them into ashes. Just a single wa3be of Sun's Lance already killed tens of fallens

Suddenly, ten powerful auras erupted and ten Grand Knight Flying Fallens appeared and locked on Sun. The Mother Fallen knew that no matter how many low levelled fallens he make Sun can just escape. That is why he decided to make Rank 3 Fallens but saying it was harder than doing it. The amount of energy required to make one was astronomical

He literally need to send his fallens everywhere to get 'food' as energy source. In the process, it killed a lot of lower levelled fallens further dwindling their numbers. To save energy the fallens eat their own kind to 'recycle' and make another ones

Sun just knitted his eyebrows but he didn't mind Grand Knight Fallens attacking him. It doesn't matter whether they are Warrior, Knight, or Grand Knight. As long as they are not in the Rank 4 of Supernatural even if there were tens of them he can still kill them easily

"[Hell Flame Magic: Flame Charge!]" Another black flames burned on Sun's wings and the next thing everyone knew was that his Lance already pierced one of the fallens' head and in just a few seconds the powerful fallen was reduced into ashes

He made it too easy to do and in actuality it was easy for him to kill Grand Knight Fallens but the problem is the energy consumption. He didn't have unlimited amount of energy and killing Grand Knight Fallens ate a lot

"This is so unfair!" The Mother Fallen hiding in the sea of fallens roared inside his mind in anger to not attract any human's attention. Fallens should have advantage over humans as they don't feel pain and their heads should be severed or destroyed to kill them. Humans on the other hand are fragiles and an injury will lower their fighting capability

Sun on the other hand is a Sin Demon, a type of special beings that were favored by the heavens and he can kill a Supernatural at his level that easily. Sun turned to look at the other Rank 3 fallens and decided to kill them before resting and recovering his energy. But first he still need to do something about the lower levelled flying fallens. Their numbers were still high and they have the ability to bypass the City walls' defense

He poured almost all of his energy on his grimoire and only left enought for him to escape. The grimoire glowed with intense black light that blinded everyone and a powerful aura erupted

Sun's lips turned into a cold smile before he called the name of his magic. "[Ultimate Skill: Burning Sun of Hell!]"

He didn't have much of a chance to use this magic as it was a trumpcard that should only be use when he's in a dire state but its might was not something that one can underestimate

Above him a black colored Sun appeared together with the heat waves from its high temperature. Instead of bringing light to the world, the Sun did the opposite. It devoured sunlights and covered the world with darkness. The weaker fallens just by getting near to it immediately caught fire and was burned to ashes

Both the humans and fallens stopped what they were doing as the oppressive might from the Black Sun was too much for them to handle. The Sun didn't just contained the power from the spell it self but it was mixed with something. Something that no one can decipher, something that was too high level for them to understand

Its like the Sun was a miniature of something that can burn everything, even Souls. Sun put his hand above him and pointed it words the sea of fallens in the sky.

The Black Sun obeyed his orders and immediately went to burn every fallens on its path. After it descended down to the fallens, the Sun made a pushing motion with his palm and the Sun travelled horizontally. The fallens can't even put a resistance and without any suspense you can't even see a trace of them. Only ashes remained

The Black Sun travelled few tens of meters and killing thousands of fallens along its way. It stopped as if the 'fuel' run out but after just a second it exploded into black flames engulfing a lot of fallens with it

The Burning Sun of Hell managed to kill more than ten thousand fallens and a huge chunk of flying fallens were permanently erased from the world

Sun's face paled from using almost all of his Hell Flame Energy but he still has his Envy energy to fight. He turned back his vision on the Grand Knight Fallens that he ignored. He didn't kill them using his Ultimate Skill as that will use a lot of energy and will kill lesser fallens. However, he can still kill them. The Mother Fallen's anger rose another level and he furiously ordered the remaining nine Grand Knight Fallens to encircle around Sun. This didn't made him feel fear though and there was still a cold smile on his face

Sun hold out his Lance in front of him while pouring his envy energy on it. Soon, the tip of the Lance transformed into an eastern looking type dragon and its body coiled around the Lance's body. "[Demonic Magic: Evil Dragon's Dance!]"

A loud sound rang as the dragon lance danced in the air and left a dragon trail. Sun circled around him like a dancing dragon destroying its path. The dragon lance easily cut the fallens on their neck. It's like he was just cutting butter using a hot knife. One can even see the path that the dragon lance took as the attack's speed was too fast

Just like that, nine more Rank 3 Fallens were killed effortlessly just by using a lot of Sun's energy. His face paled again the black lines around the envy word on his forehead retracted. His powerful aura dimmed and become weak. Sweats formed on his forehead and he felt a huge sense of fatigue

"[Hell Flame Magic: Flame Charge]" Sun used the pitiful amount of energy remaining on him and black flames appeared on his wings again to boost his speed

"Now!!" The time that the Mother Fallen was waiting for finally happened. He flew in the air without using any magic or wings and hold out his hand in Sun's direction. The fallen clenched his fist and Sun was locked by the energy around him

The normally docile free energies in the surrounding suddenly bared its fangs at him. The Mother Fallen sent a mental command on the fallens and they charged towards Sun. This was as much as he can do. He cannot kill using his own hands and can only order his fallens underlings to do the dirty work for him

"This again?!" Sin thought angrily. Due to rage he forgot that there was a fallen that can lock him on his place with an unknown method. It caused him to make a huge mistake that he would regret

----

When the Black Sun appeared Derry already turned his focus to Sun and watch him fighting. He sighed inside him when he saw how strong Sun is. Not only did he killed ten thousand fallens but he also killed the Ten Rank 3 ones

However, just when he thought that Sun would escape to not get himself surrounded he actually stopped mid air and let the fallens come too close to him

"Not good!" Derry knew there was something wrong and he flapped his wings immediately to fly towards Sun's direction while also using all the spells he can to fly as fast as possible. But he was too far and can't possibly go there in time

Fortunately, the Supernaturals that can fly that became idle when Sun started fighting immediately went to protect him and buy some time

White Holy Chains started appearing on the Mother Fallen's body but it was decisive at staking it all for the only chance of winning and removing the seal that stopped it from using all of his power. He felt too restricted at having boundless power yet he can't even use ten percent of it

All sorts of colorful and powerful magic attacks flew in the air. The Supernaturals that has the ability to fly did all of their best to kill the fallens that were coming to the strongest expert in God Tech's City

"[Lightning Magic: Chain Lightning!]" A Grand Knight Supernatural can be seen floating in the air. It's not like he can fly in the air but a Rune can be seen glowing with small lights on his chest

This guy was Eric. One of the few Grand Knights in God's Tech City and was in the middle of that rank. He's also someone who has great respect for Sun's strenght and he won't let him get killed

A single line of lightning flew out from his yellow colored grimoire and it hit one of the flying fallens. The Fallen's body convulsed violently and smokes were drifting from its body. The fallen's head was fried inside and it died

However, Eric's magic doesn't end there. More lightning appeared from the fallen's body and attacked all the fallens in a fan shape area. They met the same fate as the other fallens and their whole body were fried

A single magic of his killed tens of fallens but it was not enough. The Mother Fallen ordered all of the flying fallens to disregard their own life to kill Sun

As more time passed more chains appeared on the Mother Fallen's body. It was only a matter of time before the seal will hurt it once again while killing all of the fallen's underlings. If that happened the consequences will become more severe than the first time

The first one can be considered as a warning although it was extremely harsh but the second time was the real punishment
