The dagger can make people bleed and it takes their life slowly. When the dagger turned into a sword its appearance greatly changed.
From a normal-looking dagger, it now looks like a holy sword. The sword is about 2 meters in length. It has a gold aura around it like it is blessed by some gods.
"I can't let that thing hit me or else..." Yuki cannot possibly think of the outcome when she gets hit by that sword again. So she decided to bombard Rong Su with an attack so that he will be on the defensive and not have any chance for him to counter-attack Yuki.
After taking a plan she jumped toward Rong Su and while in mid-air she created a thousand Ice Spikes and began to control them to attack Rong Su at once. But to Yuki's surprise all Rong Su did was swing his sword and all of her Ice Spikes got destroyed all at once. Rong Su didn't break a sweat on that attack.
But what Yuki didn't know was that Rong Su was having a hard time controlling the sword's destructive power and his bones felt like breaking already but he didn't flinch because he didn't want to gamble that Yuki might see it so he endured it with all of his might.
Yuki felt her heart drop when she saw this, right at this moment, she felt like death was staring at her and she froze on the spot. For the first time in her life she felt nervous and anxious when facing Rong Su right now, she doesn't know what to do now that Rong Su can destroy her Ice Attacks with ease.
Her mind was in turmoil trying to think of a way to defeat Rong Su and finally heal Yumie's wound.
When Rong Su saw Yuki's panicked face he felt like he struck gold at the moment so he didn't hesitate and rushed toward Yuki and attacked.
And since Yuki was thinking she didn't notice that Rong Su was closing on her and only realized when they were a few meters apart but it was too late to dodge or block and she was hit by the sword in her abdomen and was sent flying because of the force.
"Sh*t! How the f*ck can I win!" Yuki began to curse herself for being distracted in a fight even if she taught Yumie that she should not get distracted and just focus on her enemy and surroundings.
"Get a grip, Yuki!" She told herself and she then began to calm down and now was able to think straight and her mind was now working normally.
So Yuki then tried again to attack Rong Su with her Ice Spikes but differently.
"It's no use, little fox." Rong Su said arrogantly and swung his sword again at all of the Ice Spikes that were forming in the air but when he tried it he was shocked that this time it didn't work.
"It's no use huh? HAHAHA!" Yuki began to laugh loudly after seeing Rong Su's shocked face but quickly composed herself and rushed towards him and began to exchange in close combat while still attacking him with Blood infused Ice Spikes that were stronger and faster than normal.
Rong Su thought that Yuki was just playing on him and didn't fully use her powers and thinking about it he gritted his teeth and his grip on his sword tightened. But looking back at Yuki's shocked face when he destroyed it easily it seemed genuine so Rong Su refuses to believe that Yuki was just playing with him.
He then tried to look at the Ice Spikes to see if something is different and looking closely at them the color seemed to have changed in color like blood 'Blood?'. Rong Su then remembered Yuki's blood attack earlier and his eyes widened at this thought.
Rong Su earlier thought that why Yuki's Ice was red before is because of the blood in the surroundings but he didn't think that Yuki can fuse her Bood Manipulation and Ice Maker skill.
After thinking for a while he then thinks that it doesn't matter. The only thing he should think about is winning the fight and saving Song Xing from Yuki even if it cost his life.
And so he did. Rong Su then rushed toward the Ice Spikes and used all of the Sword Martial Art that he have to destroy them all. The reason why Rong Su didn't use them earlier is that using the sword already put a heavy burden on his body and using Martial Arts skills only makes that higher. So he used all of his strength in this battle to win.
Yuki only chuckled and only wrote the word "Foolish!" in the air and created more Ice Spikes infused with Blood and then surrounded Rong Su.
The Ice Spikes then stab Rong Si at the same time creating some holes in his torso, arms, and legs. He was now badly injured but Yuki didn't care at all and went behind him to stab him and finally kill him.
Yuki even forgot her Quest of not killing them. The Quest only says to teach them a lesson and not kill them but Yuki seemed to forget about this and went behind him to strike the final blow.
When Song Xing saw this her heart dropped so she shouted anxiously at Yuki "Please stop! He's already badly injured." She said while running towards Rong Su.
Yuki's tail stopped just a few inches into Rong Su's back when she heard Song Xing.
Song Xing's eyes lit up and immediately rushed towards Rong Su who was now lying on the ground while coughing blood on the ground. His body was a mess, he has a few broken bones and limbs in his body and the worst injury is from Yuki's Ice Spikes. When Song Xing saw Rong Su's condition she cried while holding up Rong Su's motionless body, he has now collapsed on the ground Song Xing even thought that Rong Su is dead but when she felt his heart she sighed in relief then looked at Yuki with teary eyes.
"Thank you." That is all Song Xing said before trying to cure Rong Su's wound.
