Demon Lord's Reincarnation

Reginald who had lost function on both his arms looked at Arthur full of hatred. If only he didn't hold back at the beginning. If only he had used all his might from the start, then all of this wouldn't have happened. Those were the thoughts circling around Reginald's mind. Reginald truly regretted that moment of folly as he gritted his teeth. Still, who would expect that a child would be able to beat him. Non would expect that a child who was only half his size could bring him a Sword Saint down to his knees. In fact, many people watching were still in a daze, when suddenly Reginald shouted. 

"Damn you! Damn you! You used your age to lure me in so that I'll drop my guard. As a compassionate noble, I was tricked into showing you mercy. Damn these commoners, as expected all of you are just thrashes! Your filth does not know honor, as expected all of you are just animals! Animals the lot of you! You f*cking animals don't have the right to stand before your f*cking superiors, you have no right to even think about going against us of noble status! The lot of you are only good as slaves!" 

...

While Reginald was shouting profanities at the Arthur and the twenty, Albert and the other guild masters were in a state of shock the same as the other people watching. The battle they just witnessed was unbelievable, from the way the twenty members of the Shadow Clan easily massacred the Royal Guards, to the scene where a ten-year-old boy was able to beat down a Sword Saint, all of it left them awestruck. Not to mention that Reginald was not just any Sword Saint. 

Even though Reginald's character was the worst among the Sword Saints, his strength was still in the upper middle-tier among Sword Saints. So even though Reginald let his guard down at the beginning which led to his injury and later his downfall, Arthur's feat was still extremely impressive, that it made people doubt their eyes. Even Albert and the others who were A-ranked Guild Masters wouldn't be able to beat Reginald even if they fought together. The most they could do was stall him and when they see an opportunity flee. 

Yet this kid beat that Reginald down, and he's saying that his master was way stronger. They couldn't even begin to imagine what kind of monster Arthur's master was. Albert was perplexed, and the other Guild Masters started to look at him. 

"What should we do? Should we help the Duke?" Rick cautiously asked Albert. 

"I say that we don't help the Duke, let's just head back to the Guild and take Albert's family, and flee. Who cares what happens to the arrogant Duke, he and his ilk could all die for all I care." Samson gave out his opinion. Albert did not respond as he was thinking about what the best course of action was. 

...

"You're noisy, but I'll ask one last time. Those of you who want to surrender will be spared, and we promise to protect you. We will then guide those who surrendered to meet my master. As for those that don't then only death awaits. So who is willing to surrender?" Arthur tried using the same tactic his master would do while intimidating his opponent. He emitted his very own bloodlust and mana to the surrounding area. Unlike Ren's, it didn't make anyone throw up, pee, or faint. Still, it made the people feel unnerved. 

Some of the nobles were thinking about surrendering, while the others ordered their mages to communicate with their armies to quickly come inside the city. Reginald who was being treated by a healing mage shouted at Arthur. 

"Who would bow down to a commoner and surrender?! I won't allow it, don't you know even if you defeated me, there are thousands of men stationed outside the city! The entire noble community is on my side, which means that the kingdom is on my side, which means that I am right, that I am the rightful heir!" 

Arthur sighed as the light in his eyes faded. He looked at the twenty and was about to give out an order when someone interrupted him. 

"We of the Adventurers Guild surrender to King Ren. I hope that you can save our families." Albert suddenly spoke. When Arthur heard what Albert said the light in his eyes returned. 

"Of course, you two follow them and escort their families here." Arthur signaled two of the twenty to help Albert and his friends. Within a blink of an eye, the two appeared before Albert and the other Guild Masters. The three of them were surprised by not only the speed but the way they entered their field without being noticed. There was not even a shred of mana fluctuation nor did they make a sound. Just seeing that skill was enough to convince the three of them that they had made the correct choice. 

"Albert what the f*ck are you doing, have you no loyalty?!" Reginald shouted at the top of his lungs. Seeing him act like that Albert sneered. 

"Loyalty? Weren't we both just using each other, you never truly treated us as one of your own. In fact, I'm pretty sure after you fulfilled your part of the deal you would make things difficult for me."

"Damn you! Royal Guards what are you standing there for?! Capture the traitors and kill those that are under the fake king." Hearing Reginald's command the Royal Guards went into formation and charged towards Albert and the other Guild Masters. Seeing the incoming wave of Royal Guards Albert and the others were getting ready for battle, but before the Royal Guards could reach them, Arthur appeared in between the two groups and started cutting off the heads of the Royal Guard. The Royal guards stopped their charge and tightened their defensive formation. 

"The people of the adventurers guild are now under the protection of my master. Those who wish to harm them will be dealt with. So is anyone else going to surrender?" 

"Damnt it! Just kill the brat and capture those traitors! Don't bother listening to his crap!" Even though they heard Reginald's command, the Royal Guard no longer moved recklessly. Seeing that no one was responding and sensing that the armies that were stationed outside were coming, Arthur gave out his command. 

"Shadow Clan, escort the adventurers guild members and their families, as well as the non-combatants to leave through escape point C. You better hurry since I'm about to use 'that'." When the twenty heard that Arthur was about to use 'that' they quickly moved to evacuate everyone in the city. 

"What are you doing don't let them escape!" 

The Royal Guards tried to scatter to distract Arthur and capture the fleeing Shadow Clan and Guild Masters, but as they got closer their heads were sliced off. 

"I didn't want to use this but you forced me to! Since you don't want to surrender then you have chosen death!" Arthur shouted as his mana was bursting out.. He was about to use the trump card his master had taught him.
