Class Advancement Mission

However, the Mechanical City was a dungeon for Mechanical-type players to change their Classes. Thus, the benefits were very low. Only under special circumstances would students choose to enter this dungeon. Thus, it was normal for there to be no teams.

Li Feng didn't hesitate. Since no one wanted to clear the Mechanical City, he would go alone.

The entrance to the Mechanical City dungeon was a dark blue hole that resembled a vortex in the sea, emitting blue light waves.

Crack!

After Li Feng stepped in, a slight shattering sound was heard. However, before he could take a closer look, an ethereal voice sounded.

Ding! "Primary-Rank player has entered the Class-Rank dungeon."

"Class Advancement mission."

Li Feng's figure appeared in a desolate desert. Then, he looked at his Class Advancement mission requirements and instantly frowned.

"Class Advancement mission: Kill one of the city lords in the 12 main cities or absorb a Class-Rank Energy Source. After completing one of the missions, you can successfully Class Advancement."

"Hu, this difficulty can be said to be hell-grade!"

Li Feng's heart was a little heavy. He had once asked around about the Class Advancement missions of Mechanical players. Generally speaking, the requirements for the Class Advancement mission were determined by the player's own data. Basically, one could change their Class after killing a few small robots.

When it was his turn, he actually wanted to kill the City Lord or absorb the Class-Rank Energy Source. These two requirements inevitably clashed with the City Lord.

"You think too highly of me!" Li Feng shook his head and muttered, "Fortunately, I knew long ago that my attributes far exceeded those of the same level. I was already prepared."

The Class Advancement mission had been handed out, and he could not change it. Thus, he could only follow the requirements.

He looked around and saw a yellow desert. It was very bleak and there were almost no plants or animals.

This was the case for most of the cities in Mechanical City. For robots, the living environment was not too important.

Li Feng identified the environment and quickly understood where he was. "I'm a little unlucky to have come to the main city of Boxer Technology. I hope I don't encounter any robots going out to battle."

The Boxer Science and Technology Main City was adjacent to the Hex Science and Technology Main City. However, there was also a distance of 800 to 900 kilometers between the two cities. Furthermore, the Cyber Science and Technology Main City was very warlike and would often engage in external punitive expeditions. Thus, it caused the surrounding environment to be the most damaged, causing this area to be very desolate.

Then, Li Feng chose a direction and avoided the main city of Bossel Technology. Then, he started walking.

In the blink of an eye, three days passed.

Over the past three days, Li Feng had also walked 250 kilometers. The Goddess of Luck still favored him and didn't encounter any robots that Boxer had deployed.

Meanwhile, he was getting closer to Hex Science and Technology City.

"Who is that?"

On the fourth day, Li Feng's luck had also ended. Eight slaughter robots appeared in front of him.

These slaughter robots had very strange appearances. Their bodies were made of metal, and their heads were like small missile heads. They had no legs, only two drives. Furthermore, there was an X mark on their bodies.

Li Feng recognized that it was a robot created in the Bossel City.

"An enemy has been discovered…"

"Execute the plan to eliminate all obstacles in front of us."

A cold, emotionless machine voice sounded from them.

"Go."

However, Li Feng was even faster. When he encountered this group of killing robots, he didn't hesitate to attack. Then, he summoned 10 RX Pursuers.

Rumble…

Terrifying flames engulfed the eight slaughter robots in front of him. Then, a hurricane raised sand and covered everything.

Buzz buzz…

However, before Li Feng could reveal a happy expression, the sound of teleportation belts moving rang out in the surroundings. This made his expression change slightly. "He wasn't killed in the explosion?"

As the sand dispersed, four of the eight slaughter robots walked out. They were also seriously injured, and most of the metal bodies had melted.

Upon seeing this scene, Li Feng heaved a sigh of relief in his heart. It was fine as long as he wasn't unkillable.

"Go." He summoned three more RX Pursuers and charged forward.

"Didi, enemies that are unable to resist, please provide support."

"The enemy is very dangerous. Please provide support…"

As the RX Pursuers exploded, the four Boselle killing robots sent out a final communication signal. Then, an invisible electric wave crossed space and time.

This situation made Li Feng cry inwardly, "This is troublesome."

The reason why he was in a hurry to make a move was not only because he could not negotiate with the robots, but also because he was afraid of exposing his position.

This was because every killing robot that came from the main city was almost equivalent to an enemy's eye. Thus, very few students in the institute were willing to enter the Mechanical City dungeon.

Then, Li Feng didn't stay for long and headed straight for Hex City.

The few killing robots he had encountered were the lowest-leveled robots in the main city of Bossel. If he was surrounded in the future, there might even be missiles locking onto him.

At that time, it would really be a situation where death was certain.

…

…

On the fifth day, Li Feng only walked 100 miles. His speed was much slower than before because a group of flying robots attacked him today.

He could not fight it head-on, so he could only dodge far away and take a detour. He also suffered considerable injuries.

"We're still more than 200 kilometers away from Haix City. I hope nothing happens again." That night, Li Feng drank a bottle of blood recovery medicine and secretly heaved a sigh of relief.

He wasn't far from his destination now.

During this period of time, Li Feng had maintained a concealed state. He didn't even summon his RX Pursuer. This was to avoid being discovered by the slaughter robots.

Buzz buzz…

At that moment, killing robots with huge sickles in their hands appeared around him. Their eyes glowed red and they instantly locked onto Li Feng, who was in the darkness.

The Concealed Skill did not have any effect under the red light. This made him shocked. "This is not good!"

Boom boom…

Several laser cannons shot towards him. The light of the cannons pierced through the darkness with terrifying power.

"The coordinates here are… The enemies have been completely exterminated."

The infrared rays shot out from the eyes of these sickle robots swept across Li Feng again. Then, they discovered that Li Feng, who had been struck by the laser, had completely evaporated. Only then did they send out a signal and slowly retreat.

After an unknown period of time, no one noticed that a black shadow gradually appeared on the ground. In the end, it transformed into Li Feng.

His face was extremely pale. "If I didn't obtain a passive skill that allows two figures to fight each other, I would have really died."

He hadn't expected that his concealed state would be useless under the infrared scan.

"Hu!"

After a long while, Li Feng finally calmed his palpitating heart. "I won't be able to use my figure to swap for the next two days. I have to be careful."

Then, he summoned his RX Pursuers one after another and hid in the surroundings to warn him. Since hiding was useless, Li Feng didn't hide anymore.
