The leader was a man in a light armor suit. He saw Mark sitting by the river and walked towards him.
"You must be Mark! I'm sorry to have kept you waiting. How's the situation now?" Brand Eddy knew that Mark was a student of the Empire Magic Academy, so he appeared very enthusiastic.
Mark stood up, turned around, and said everything that had happened in the sewers.
"I see!"
"I'll have to trouble you to bring us to the entrance of the underground cave!"
"Lead the way. Leave the battle to us!"
Hearing this, Mark nodded and led the four armed men into the sewers.
With his astonishing memory, Mark walked for more than an hour and brought the four of them to the entrance of the underground tunnel.
"This is the place. Please be careful!"
"When I entered, I triggered something similar to an alarm. I think there are more than just zombies inside."
After hearing Mark, the leader nodded and led the team deeper into the cave.
Mark quietly waited outside the cave to prevent anyone from escaping.
Not long after they entered, an intense battle occurred below, because Mark heard a huge explosion outside the cave.
Then, after a period of silence, the sounds of magic became softer and softer.
After half an hour, there was no longer any movement in the underground cave, but the team that had entered still did not return.
This made Mark worry!
Just as he was considering whether to go in, a pile of zombies appeared in the cave. Mark pulled out the longsword at his waist and killed the zombies before entering the cave.
"There's no helping it!" With that, he rushed deeper into the cave.
Soon, Mark found the reason why they had not come out!
This underground cave was too dangerous. After traveling for half an hour, Mark still had not reached the end.
Every once in a while, a huge space appeared. Every space was filled with monsters transformed from various creatures.
By the time Mark arrived, the monsters had already turned into corpses. Only a few slightly tenacious creatures were still squirming.
After traveling for half an hour, they finally arrived at a huge door.
The huge metal door had been blown to the ground. From the outside, one could clearly hear the fighting inside.
Leaning over, Mark could see that the huge room was very spacious. There were shattered glass equipment everywhere.
Through some glassware that had not been shattered, Mark realized that these things were all created monsters!
In the middle of the hall, the four-person team was fighting a huge and ugly monster.
Behind the monster, there was an abnormally ugly man watching the battle.
In his eyes, Mark did not feel fear. Instead, he was meticulously observing the monster's combat state.
As the battle continued, the man continued to fill in some data into the magic tool in his hand.
"He still has the mood to fill in the data at this time. Looks like he has other tricks up his sleeve."
The battle quickly came to an end, and the monster in front of the four-man team fell.
After the battle ended, the four-person team immediately surrounded the man in the white coat.
At that moment, an accident happened!
A light appeared around him, and in a moment, his figure disappeared from the four-person team.
"Damn it, he prepared a teleportation array!"
At this moment, Mark walked in and looked around the room. He did not find anything unusual.
After the ugly man in the white coat left, the equipment in the room seemed to have malfunctioned and a weak explosion occurred.
Everything was destroyed in this basement.
Brand Eddy came to Mark's side, "Thank you so much for this!"
"Someone will take over from here. You just have to accept the reward in peace."
"I will report the rest to the head of the Garrison Guards." With that, he patted Mark on the shoulder and turned to leave with his team.
Human experimentation was also not allowed on this continent.
However, it was not strange, so the four-person team left without any investigation.
After they were far away, something abnormal suddenly appeared in Mark's body. Black and white light flashed around him.
This light absorbed everything that could not be seen with the naked eye in the entire basement, and then returned to Mark's body.
Mark was helpless regarding this matter.
The last time such a thing happened was with the demons. He did not expect the same thing to happen today.
Even if he felt something amiss, there was nothing he could do. Mark could only shake his head and leave.
When he returned to the ground, it was already noon. Before he left the slums, the magic communication device sounded.
It was an unknown number.
When the call connected, he heard Senforia's voice, "I heard at home that you've been working for the Empire's Garrison Guards recently!"
"Didn't I instruct you not to secretly complete a mission while I was away!"
Hearing this, Mark smiled. Then, he told them about Nelson Ashborne helping him and why he had done these things.
After hearing Mark's words, she calmed down, "I see!"
"Since it's to repay a favor, I won't pursue it."
"I'll be back in a week. I'll finish the mission in my hand. You're not allowed to accept other missions!"
With that, she quickly hung up.
...
After hanging up, Mark went to the Garrison Guard Station to receive his payment from the reception desk.
Because there was a huge accident this time, the Garrison Guard Station directly gave Mark 500 gold coins as a reward and more than 10,000 guild points for this mission.
Taking the money, Mark turned around and went to the Empire Bank. He saved all of this money and obtained a magic savings card.
With money, he naturally had to purchase a superior weapon.
The longsword he had bought with a few gold coins had many chips after his last battle with the student from the academy, so Mark had to change to a new weapon.
Arriving at the blacksmith shop at the corner of the street, the shop owner immediately greeted Mark, "Long time no see!"
"Have you been busy recently?"
"It's manageable, there's a lot to learn while doing guild missions!" Mark nodded and smiled.
With that, he took out the longsword at his waist, "Can you help me forge a better longsword?"
"This one is almost unusable now because of an accident!"
The shop owner picked up Mark's longsword and glanced at it, "Looks like you've experienced an extremely intense battle recently!"
"250 gold coins. I'll help you forge a superior longsword."
Because all the money was saved in the bank, Mark took out his card.
"Can I pay with a card here?"
The shop owner glanced at the card in Mark's hand and smiled, "No, but you can bring the money next time!"
