The Wyvern prepared for his strongest skill, the Wind Tornado. The skill affects a wide area and is also powerful enough to knock out Rank-C humans.
The only downside of this attack is that it takes too much time to charge. However, it was no problem here because nobody had a powerful enough long-range attack to disturb the Wyvern leader.
I could try to use my Dual Art: Shadow Ice Shard but there were other Wyverns standing in front of the Wyvern leader to defend against the enemy attacks.
I still had another option, though I was not sure whether I can pull it off or not but it was better than doing nothing. I poured in the remaining mana and released the Ice energy.
[ "Ice Embodiment: Ice Creation" ]
I used all my mana to create something like a big stair of Ice for the students to climb and reach the Wyverns. The other Wyverns can be taken care of by other students while Hiro could go and disturb the Wyvern leader.
The Ice stair was created as high as 25 meters high. You might as well say that I build a building out of thin air.
While students were in despair, suddenly an Ice Stair appeared out of nowhere in front of them. They were startled by the sudden emergence of an Ice Stair.
[ "Go and Attack him now!" ]
I shouted at the top of my lungs to bring the students back to reality. The students understood from my words what they had to do.
One after another the students started climbing the stair and got engaged in battle with the Wyverns.
[ "Come on! Let's Go!" ]
[ "Attack the leader while he is still charging his skill." ]
[ "It is do or die. Everyone climbs the stair." ]
More and more students started climbing the stairs. They were moving closer to the Wyvern leader until they got stopped by other Wyverns.
The other Wyverns came between the students and tried to stop them. The Wyvern leader was still charging his attack.
Hiro and Lisa also went to interrupt the Wyvern Leader.
[ "Athena Blessing: Heavenly Strengthening" ]
Lisa used a wide area support skill that increases the attack power of people near Lisa albeit by a little percent.
But when 10s and 20s students' strength is increased by a small percentage, the combined power of that small increased strength would be huge.
Hiro ran at full speed towards the Wyvern leader. The other Wyverns tried to stop him but Hiro easily killed them and quickly reached near the Wyvern Leader.
[ "StarShatterer Style: Star Annihilation" ]
Hiro was able to injure the Wyvern leader and interrupted the Wyvern leader's skill. Now that Hiro was close to the Wyvern, he could finally use his strongest attack.
Many students also found fighting Wyvern easier as Wyvern's advantage of flying was not there anymore.
The sound of battle filled the area. I took the opportunity to drink a mana potion. My mana has reached 20 percent.
Hiro was engaging in close combat with the Wyvern leader. Even without the Wyvern leader's advantage of flying, the Wyvern leader was easily overpowering Hiro.
Hiro was even reinforced by Lisa's Blessing but Wyvern's leader was incredibly strong. It is extremely difficult for even the Rank-D+ peak to beat Wyvern Leader who is in Rank-C. Not to mention Hiro who has only recently attained Rank-D -.
Hiro attacked fiercely but the Wyvern leader easily blocked his attack with his barrier. Then Wyvern's leader counterattacked.
Lisa used her skill to protect Hiro from Wyvern's attack. Sometimes her barrier completely blocked the Wyvern attacks while at other times she would just reduce the power of Wyvern attacks.
Hiro and the Wyvern leader were both in a fierce fight with neither being able to defeat the other.
Meanwhile, Zion was on the verge of defeating his opponent, Rank-D Wyvern.
At first, Zion was at a disadvantage as his Imperial Spear Style was mainly for close combat. He could only defend and try to keep the monster away from others.
After Zero's Ice Creation, he was also able to close the distance between him and Wyvern which enable him to take a more offensive approach.
[ "Imperial Spear Style: Obliterate Strike" ]
Zion used his strongest attack to completely obliterate the Wyvern.
Zion sat down and took a rest for a while. Zion was injured earlier when he was still in his defensive position.
While he managed to avoid any lethal wind slashes but still he was occasionally hit here and there.
Blood dripped from every part of his body as multiple Wind Slash had cut every part of his body.
On Sylvia's side, she had an easier time than other students. She is a bow user, therefore she was not at all at disadvantage due to the distance between her and the Wyvern.
She had been attacking the Wyvern continuously and dodging the attack of the Rank-D Wyvern. She was fighting a war of attrition and it was only a matter of time before she brings down the Wyvern.
However, Sylvia had to be cautious all time and dodge the attacks of the Wyvern. One hit from the Rank-D Wyvern was enough to knock out Sylvia.
I looked around and saw that many students were doing well now. The only problem was the Wyvern leader who was ridiculously powerful.
Hiro is somehow able to keep the Wyvern leader busy with the help of Lisa but in the process, Hiro is constantly being injured while Wyvern's leader was not taking any damage.
If this continues, Hiro will lose and then Wyvern's leader will attack us. All the effort we put into fighting the Wyverns will be for naughts.
I thought of the optimal way to defeat Wyvern's leader. I can try to use the strongest attack that I can muster but I needed a little more mana to be able to execute it. And I am also not sure whether my body can handle the stress anymore.
Both mana and my physical condition were not in great condition.
[ "Imperial Spear Style: Obliterate Strike" ]
The battle with Wyverns turned more favorable when Zion joined the fight but the situation was still not looking good for us.
Even with the additional firepower from Zion, the Wyvern leader was too damn powerful to be taken out.
Hiro and Zion continued striking without being able to break the Wyvern leader's defense.
The two of them used the most powerful skill they had simultaneously.
[ "Imperial Spear Style: Obliterate Strike" ]
[ "StarShatterer Style: Star Annihilation" ]
The Wyvern leader's defense broke but the damage on the Wyvern leader itself was not that great. They did manage to make a small cut on the Wyvern leader's chest.
The Wyvern leader became annoyed by their attack. Even though it didn't do much damage to him, still being hurt by others was not a good feeling.
Wyvern's leader realized that his attacks are being blocked by Lisa after his attack was constantly blocked. Wyvern's leader ignored Zion and Hiro and attacked Lisa.
In a single instant, multiple Wind Slash was shot out to Lisa.
[ "He is going after Lisa. Lisa dodge!" ]
Hiro and Zion tried to block the attack but it has already passed through them and was approaching Lisa.
At the same time, Wyvern Leader continued to launch his attack again. Although Lisa managed to dodge them with her nimble movements and her protection skill, the attacks became fierce and fierce until she could neither dodge nor hold her barrier.
Eventually, the attack broke past Lisa's barrier and hit her body, sending her flying like a football being kicked. Since she was on the Ice Stair that Zero made, if she landed on the ground which is 25 meters high, she would definitely die.
She coughed up blood and looked at the ground. She could do nothing but close her in an attempt to stop her mind from being afraid.
