Since Yunan had cleared the 25th level he was then eligible for the next phase of training, mercenary work. It was the next step in the growth of adventurers: working with strangers.
For the next month Yunan would join a party per week, he would fill in for whatever roll they needed in the party, with Yunan's kit he was suitable for this kind of training, and so Yunan went to the guild and asked for a the opportunity to join a party that is looking for a new addition. There were 5 parties in the 20th to 29th floor range who urgently needed a new recruit. Yunan chose a party that were in a hurry to reach the 25 floor, they promised a bonus for defeating the bosses of each floor and even an equal share of loot.
The party was made solely from beast-lings, there were a total of 30 in the party including Yunan, the only human in the group, according to the party, they were going to set up camp in the 25 floor and then go down slowly from then on, Yunan was hired as a damage dealing magician, simply because the party had to deal with the rat floor and they brought 20 shield bearers at once. Yunan told the leader that he can lead them within a week to the 25th floor as long as they stayed within 30 meters from him and did not do anything stupid.
Of course there were dissenting voices and many arrogant and condescending faces and they all looked at Yunan like a lunatic, there was no way in hell they could reach the 25th floor within a week, not even level 30 can do it, however Yunan just said "as the hired muscle i can only tell you about what i can do, as for if you use it or not is up to you". The leader thought for a while and discussed with his closest aids before saying "if you clear the spider queen with in one day, you get to order everyone here to your every whim, the loot will be yours, all of it if you can get us to the 25th floor within 2 weeks".
Yunan just smiled and did not say anything, the meeting was later dismissed and Yunan was told to stay with some members in case of unforeseen circumstances and he obliged. The party was very solemn, they slept and rested almost all the day, eating light and energy rich foods and checked their preparations for the 100th time. Come dawn, the party headed out and descended to the 21 floor.
After everyone reached the floor, Yunan gathered them closer and said " i will now apply a major buff to everyone, the buff is active as long as you stay within 30 meters of me, you will feel like your body is different and will take time to adjust to, please spend the next hour carefully adjusting to the new level of power". During the speech many accused Yunan of delaying and speaking nonsense.
Yunan touched his medallion and activated it mentally, the medallion swallowed him in full armor, then he activated one of his new armor skills, "aiding aura" it gives a 150% attribute buff to all allies within an adjustable range to 30 meters because that would save him some mana and make him look awesome but not too awesome. The party changed from criticism to awe and wonder. "I think doing jumps and punches, and some basic exercises would be great in helping you gauge the new strength" Yunan told the party as he sat down and took out a piece of meat to chew on.
After 10 minutes everyone had roughly gotten used to their new found powers, Yunan started to walk slowly, then increased the speed slowly allowing the rest to catch up, he went straight to the boss room according to his own map, and within 3 hours everyone arrived there without as much as a scratch because anything that got within 100 meters was dead and collected like an afterthought. Outside the boss room Yunan told the troop to rest for the time being, he could not understand why a level 20 adventurer would get tired after running for a few hours, not to mention the 150% buff. "eat as much food as you can, the buff makes your bodies burn almost three times as much energy" Yunan advised the party and stood still providing protection for what he considered dead weight.
After everyone was fully restored, Yunan led the way into the spider queen room, there were still as many spiders around as he remembered. Yunan told his fellow to not do anything and just watch, he waited for the spider queen to start the fight and activated his 100 meter radius maelstrom, a blender of elements in chaos, the maelstrom kept the huge number of subordinates at bay and gave Yunan a shot at the queen that was taken immediately, a rain of ice spears later and the spider queen was dead.
Yunan did not explain as he pocketed the corpse and the items that were in the chest without saying much, and led the group to the 22 floor, he told everyone to just sleep and rest because the toll of the buff was too much to bear, and Yuan only planned to help them get faster and run better. Yunan was thinking about how to deal with the gargoyle when the leader approached him, he was impressed with Yunan and tried to rope him in, but Yunan politely declined stating that this mercenary work was just part of his training, and that Yunan was the type of adventurer to work better alone.
Yunan took some rest but did not sleep fully because he was responsible for the safety of these people simply because he thought that losing an adventurer was a hit to his own reputation, something he should avoid for future jobs if he wanted to keep doing this job later on.
