This was Joel's second headache attack today, which had never happened before.

He reached for the vial and drank down what little medicine he had left. After the pain recovered, the words "Alien Gate" appeared in his mind.

The Gate of Difference...... What was it? This question had been haunting him since his last mission.

A month ago, Joel received a summons from Edetta in the middle of the night, while he was asleep. Edetta handed him a roll of parchment and instructed him to assassinate the target above, solve it as quickly as possible, and set off without delay. Surprised by the urgency of the mission, Joel asks Edetta why, but Edetta keeps silent and sends him away with a cold eye.

Normally, Joel doesn't bother to know why Edetta wants to kill, because it's only his job to get rid of those targets. This time, however, Edetta's reaction was very unusual, completely losing his usual calm and calm demeanor, appearing eager and flustered, but unwilling to confide in him the details.

This aroused Joel's great curiosity, and he decided to explore it on his own during the mission.

When it comes to killing the first few targets, Joel doesn't find any clues. He only thought that these people were mediocre and timid folk wizards, until he met the target called Hugh.

Hugh is also a wizard of the Crown Society, but the notes on his drawings say "High Wizard, Dangerous".

Seeing such words, Joel's heart was actually excited. He has been on missions for Edetta for a long time, and he has killed countless people, and the simple assassination is just a mechanical and boring job for him, just like eating and drinking, and there is no turmoil in his heart. He needed a challenge, something to stimulate his fighting nerves, to stimulate his bloodthirsty soul, and only then would he be able to stay focused as a killer.

Early that morning, Joel had just crept into Hugh's courtyard when he saw Hugh carrying a bag and about to go out. He was going to go straight to it, but seeing that Hugh was in a hurry, it seemed that he had something important to do. Joel decided to take a look and see what the wizards were up to make Edetta want to kill them.

So, he began to follow Hugh. As an excellent assassin, Joel is naturally very skilled in tracking skills. He is light on his feet and confident that he will never be detected.

Hugh went out and walked north, his steps as fast as if he were flying close to the ground. Joel followed Hugh at his usual pace, feeling a little struggling. This surprised him, he didn't expect this wizard to have such foot strength, so he had to speed up his pace so as not to lose his target.

After Joel followed Hugh two blocks, Hugh abruptly changed direction and headed straight west of the city.

"Am I being discovered?" Hugh's unusual course of travel made Joel question, but his self-confidence quickly dispelled the idea. He adjusted his pace slightly and continued to track.

Hugh headed all the way west to the west gate of the Ice City. The outside of the city was open and there were few covers, and Joel could only use the sparsely growing trees to cover himself.

At this time, Hugh was already in front of a wasteland.

"What is this guy doing in such a remote place?" Joel leaned his back against the trunk of the tree, and looked sideways at Hugh not far away, unable to fathom his behavior.

It was too late, it was too soon, and in the blink of an eye, Joel felt the sound of the wind behind him, and the rattle of leaves overhead. With his reaction as a professional killer, Joel immediately instinctively jumped to the side.

Behind him, Joel turned his head to see that the big tree as thick as a man's waist had been broken by a wave of air, and the broken trunk of the first half of the tree slowly fell, raising clouds of dust on the ground.

Joel couldn't help but break out in a cold sweat. With such a powerful air bomb, if he hadn't reacted quickly and dodged it in time, I really don't know if he would have been able to save his life.

He looked over to Hugh, and saw Hugh holding his right arm up, palm facing where he was, and steaming hot air between his fingers. Obviously, the wizard in front of him made the masterpiece just now.

Being able to get started in such a short amount of time, and with such great power, Joel recalls the wizards he had encountered, who were definitely among the best.

But as a professional killer, Joel has the ability to remain calm in the face of extreme danger. He quickly swept his surroundings into his eyes with his peripheral vision, and thought about the next step in his mind.

"Boy, who are you?What are your intentions of following me all the way?Confess sooner, I may be able to spare your life!" Hugh's voice sounded like a bell, and even in the vast wilderness, Hugh's voice still sounded as loud as Joel's ears.

"He had already discovered me, and had brought me here to kill me where no one was around...... This guy is not simple, he can detect my stalking......" Joel thought.

Seeing that Joel did not respond, Hugh shook his hand again and threw four air bombs at Joel in a row.

Seeing this, Joel did not panic, but used the time slot of the air bomb flying in the air to dodge in an instant, and at the same time carefully observe the opponent's moves.

He has always believed that there is no perfect move, whether it is a blade or a spell, all moves must have a way to crack, and the best way to deal with it is to stay calm and look for the enemy's flaws. This creed has helped Joel turn defeat into victory in dangerous situations countless times, so he is convinced of it.

Hugh's air bombs continued to shoot around Joel in groups of four, intending to block all of Joel's dodging directions. The size of the air bomb is very large, and Joel can only use the gap created by the order of arrival of the four air bombs to dodge sideways, if the four air bombs are fired at the same time, Joel will definitely be hit.

"All moves have flaws. Joel once again silently thought in his heart, "If you can't fire air bombs at the same time, it's a dead hole!"

After figuring out the weaknesses of the opponent's moves, Joel is calmer. He looked at each air bomb, found the gap between the air bombs, and quickly approached Hugh as he dodged.

Such a move was clearly beyond Hugh's expectations. He probably thought that Joel would be able to dodge it was already difficult, and if he continued to attack, Joel would soon be hit by the drop in physical strength, but he must not have expected Joel to be able to dodge and still be able to approach him.

Hugh's expression became flustered, and the air bombs he cast began to be crooked and messy. Even the most powerful wizards struggle to cope with the melee attacks of trained warriors. For a wizard, if he is not able to maintain a certain distance from the enemy, and keeps the enemy close, it is already a failure in itself.

As the distance got closer, Joel's form became more and more ghostly. Hugh noticed that he was finding it difficult to see Joel's movements. When Joel was only two steps away from him, he was ready to use all his mana to cast an oversized bomb. This kind of close-range spell casting is very dangerous, and the magic ball with huge energy will burst, even if you can kill Joel, you will die for a lifetime, and it is really the last fight in a desperate situation.

But it was too late, and while he was still gathering mana, Joel had already stabbed him in the chest with a sword. The sword was so clean and neat that even the blood flowing from the wound was well controlled, and there was no spill at all. Hugh's body fell backwards like a kite with a broken string.

With a "bang", the short sword was sheathed, and the corners of Joel's mouth rose evilly, and this assassination made him feel enjoyable.

Although he had just returned from the brink of life and death, Joel had no sense of fear. He walked over to Hugh's corpse and saw that Hugh's legs were still twitching, and his eyes were round, as if he had left with shock and reluctance.

"Let me see what you're loading. Joel reached out and ripped off Hugh's baggage.

The burden was light, but it was tied tightly, and Hugh tied two dead knots firmly on it. It took Joel a bit of work to get it open, and there was only a small box and a parchment letter.

Joel opened the letter, only to see that it read: "My lord, the demon spirit has been catalyzed, the door of alienation has been opened, and all the conditions necessary for action have been met. It's just, as you guessed last time, that guy really has a bad idea. Time is running out, and if the problem is not resolved as soon as possible, the consequences are unpredictable. The location of the alien gate cannot be known to outsiders, so I suggest that you start it immediately and ask your adult to give instructions. Hugh's handwriting. ”

"Demon spirits, alien gates...... What does all that mean?" the unfamiliar words left Joel scratching his head. "Who are the so-called adults and that guy in the letter?" Although Joel recognized every word on the letter, after reading the entire letter, Joel didn't understand what Hugh was doing, what was the secret behind these wizards, and why Edetta was so eager to kill them.

He took out the box again and put it in his hand to examine it. It's a cube box, small but delicate. Joel didn't see the material, only that it was strong, heavy, and dense. There was no lock on the box, but Joel couldn't break it. He used all his strength to strangle his fingers, but the box was still tightly closed.

Joel judged that the box was magically locked, and that it must contain something very important based on the sturdy material of the box and the strength of the magic lock.

The Magic Lock is a cumbersome spell that is easy to lock and difficult to open, requiring an hour of casting to unlock a lock. Generally speaking, mages do not have more than two magic locks, because two magic locks are impossible for most people to brute-force, and the time required to unlock them is long enough, and the caster does not need to continue locking them, otherwise it will take a long time to unlock.

But Joel is so powerful that he can tear open the three-tiered magic lock with his bare hands. And the box in front of him was extremely strong, obviously through more than three magic locks. Hugh is willing to expend such effort to lock a box, the contents of which must be extraordinary.

Joel carried the box in his arms, believing that the wizards must be carrying out some kind of conspiracy, and the secret was the box in his arms and the "strange door" mentioned twice in his heart.

These secrets had nothing to do with him, but this time, for some reason, his curiosity was stronger than ever, and he decided to dig out the truth behind them from the rest of his targets.
