The three fought the ghouls every day, and with each successive monster wave, the difficulty increased. But they didn't give up and cleared all of the waves.
It's been eight days since they entered this tutorial, and they have faced about fifty monster waves.
With each monster wave, the difficulty rose. In the wave that just ended, ghouls attacked from three sides surrounding the tower and in a very large numbers. Not just that, even the number of elite monsters, the Red Ghouls increased to around fifty during these raids.
On the fifth day, during the last wave of the day, a new monster joined the fray. It was the final boss monster that the people in the blue gate had to face to clear their tutorial trial, a level 18 boss monster. But the one Arya and his companions faced was a level 20 monster.
[Ghoul General Level - 20.]
This monster was at least double the size of normal ghouls reaching the height of 9-10 feet, with rusted silver armor and a great sword as its weapon.
Though the monster was strong, it was just a little stronger than the rest of the monsters. Arya, being a few levels higher than the General, easily overpowered and killed it.
Now on the eighth day, the difficulty had risen significantly. Though it wasn't much for Arya, the same wasn't true for his teammates.
As the number and level of the ghouls increased, quite a lot of the monsters managed to slip past Arya and Aetherius and were able to reach the tower, causing Rohan whose work was to kill those to manage to reach the tower, to fight a lot and even get a little injured.
On the other hand, Aetherius was able to defeat his enemies. Since he was stronger than these monsters individually, but their numbers were too overwhelming for him and even he got injured and tired during the fight.
Not to mention the special monsters. In this wave, there were around five Generals of level 23 each, three of which were killed by Arya and two by Aetherius.
After the wave, they were very tired and injured. They bought potions from the store to heal themselves, which helped them recover physically. However, they were also mentally exhausted from fighting continuously for eight days.
Arya, noticing his teammate's condition, decided to motivate them and also discuss a new strategy for the upcoming monster waves.
" Cheer up, guys! Only two days remaining, We can easily clear this. Just few more monsters waves."
Seeing Arya trying to cheer them up, both Aetherius and Rohan smiled and nodded, showing that they would continue to fight the monsters.
"So, I was thinking of a new strategy. We know the Red Ghouls explode five seconds after dying. In those five seconds, we can use them to kill the other ghouls. Until now, we just let them explode. But what if we use them as portable bombs to kill large numbers of ghouls at once? That will be a great help for us."
Listening to Arya, both Aetherius and Rohan realized it was a good strategy. But they wondered how to implement it, as they would have to lure the ghouls, contract the Red Ghoul, kill it at the right moment, and get out of range.
Arya understanding their doubts explained, "During all this time, I've noticed a few things. First, our tower is made from very strong material and won't break from the explosion. Second, as the goal of the ghouls is to destroy this stone on top of the tower, they will come to us themselves. All we have to do is stop them from climbing the tower and detonate the Red Ghouls on them."
After Arya explained his complete plan, both Aetherius and Rohan agreed.
...
Soon, the first wave of the ninth day started. This time, ghouls were coming from all four sides from the forest that is surrounding the tower.
Seeing the monsters moving towards them, Arya, Aetherius, and Rohan started taking out some containers from their inventory and applied the content of these containers, all over the tower walls.
These containers had oil, that They had bought from the shop during the resting time.
When the ghouls were about five hundred meters from their position, both Arya and Aetherius jumped down from the tower and sprinted towards the ghouls.
After reaching the ghoul, they didn't killed them but did something different this time. They didn't kill a single ghoul; they just picked up one Red Ghouls each and ran back to the tower.
Though the Red Ghouls tried to free themselves from Arya and Aetherius by using their claws, they didn't succeed as they were weaker than both Arya and Aetherius. After reaching the tower, both Arya and Aetherius used their full power to jump, and reached directly to the top of the tower and waited for the rest of the ghouls to reach them.
These ghouls were neither very strong nor very fast. Their main problem was their sheer numbers.
Soon enough, the ghouls reached the tower and tried to climb using their hands and claws. But due to the oil, they slipped and fell. But they didn't stop, and this continued for a long time, causing a large number of ghouls to gather all around the tower, This includes all three types of these ghouls. The Normal ghoul, the Red Ghoul, and the Ghoul General.
When a large number of ghouls had gathered, Arya and his party started executing their plan. They killed both of the Red Ghouls they had captured at the same time and threw them at the monster horde below the tower.
In five seconds...
*Boom!!*
*Boom!!*
The Red Ghoul that they killed and threw exploded, Following the explosion, the tower walls caught fire due to the oil they applied on it beforehand, and the remaining Red Ghouls that were in the group of ghoul surrounding the tower died in the explosion also started to explode.
*Boom!!*
*Boom!!*
Seeing the explosion, Arya, Aetherius, and Rohan had the same thought:
'Explosion is an art.'
