"You dare to hit Renner's head. Renner is very angry!" A burst of burnt smoke came out from the boss's head, and then a pair of mechanical arms changed into chainsaws as big as millstones, spinning wildly like a tantrum.

Mechanical whirlwind slash!

Boom boom boom! Lu Chen cut down the metal wall with a sword on both sides of the passage, which had almost no trace, and was directly sawed by the boss. However, Lu Chen jumped to the top of the passage with his sword and sucked himself on the metal ceiling with a [big magnet] prop.

After releasing the skill boss, he immediately became angry when he saw that Lu Chen was unharmed and activated the second skill [High Temperature Ray] without hesitation.

This is what Lu Chen is waiting for!

[Advanced · Wrath of the King]! This is the enhanced explosion skill of [Book of Ancients] bought by Lu Chen at a high price. Now this skill can make Lu Chen burst out with 200% of his own attributes, and it will last for 30 seconds and enter a half-hour weakness.

Lu Chen, whose health volume instantly increased to nearly 40,000, landed straight down with a high-temperature ray that had been hard for half a second, and rolled to the boss's feet.

"Hiss... the boss has activated the explosive skill, and he actually lost one-third of his health in half a second by the boss!" Mio Shang and the other two were frightened. If they did not use the explosive skill, if the boss's skill fell on more than 0.8 seconds, they would have to die!

After all, the professional composition of their five-person team is problematic, with high offensiveness and weak defense. Lu Chen, who worked part-time in MT, is still responsible for a considerable output task most of the time.

"Look!" Hua Kaiyu Luo exclaimed. It turned out that when Mio Shang was talking, Lu Chen had already rolled around the boss's feet in a mess. The boss's high-temperature ray that could easily penetrate the metal wall also saw the floor through a round hole smaller than the boss's body.

With a bang, the boss's round mechanical body was stuck in the hole and could not move, becoming a target!

At this time, Lu Chen was rubbed by the high-temperature ray several times, and his health decreased to an extremely dangerous level. Hua Kai Yu Luo immediately entered the field. A god-level skill [Three Hearts Spell Casting] that he started using a few seconds ago was used. Three different healing techniques fell on Lu Chen in turn, saving his life!

Fortunately, the boss's skill lasted only 6 seconds, and Lu Chen quickly escaped from danger. Then he took advantage of the explosion and threw all the attack skills except [Ghost Claw] on the boss, and suffered 300,000 or 400,000 damage and retreated.

The Silent Ram and Mio Shang have also entered the field. In the rooms that were bombed open on both sides of the passage, they use some obstacles as cover to attack the boss.

Ou Yibai ran behind the boss, and relied on the thief, a second-level passive skill with damage bonus attacks behind him, and started to output frantically.

Lu Chen was so tired that he suddenly became a wilted brother after the explosion ended. He fell to the ground softly and didn't want to move. At this time, his all attributes dropped by 90%, and even a level 30 fishman monster could kill him.

"The boss's [mutant metal] skill is to throw some things at you, and then let you temporarily have mechanical outer armor to attack your teammates uncontrollably. If anyone gets this skill, he will automatically run back at full speed!"

Lu Chen crawled into a room next to him and stuffed himself into a glass cabinet so as not to accidentally kill the controlled teammates. The quality of this glass should be of excellent quality when it appears on a spacecraft.

"Ah..." As soon as Lu Chen finished speaking, Misu Shang shouted in annoyance, then ran back. Unfortunately, he was short and ran for more than ten meters away. The liquefied metal that could deform at will was completely spread out on him, wrapping up all his body below his head, and then controlling him to walk back.

"I'll go...you guy is brave!"

Ou Yibai relied on his super agility, and did not react when he saw Mio Shang coming to her, and he still leisurely outputted to the boss. She originally wanted to wait for Mio Shang to start singing before leaving, but unexpectedly Mio Shang held up the staff and swung her over, which made her confused.

"Hahaha... Xiao Lingzi, you're done, dare to beat our wolf clan's number one sister!"

Hua Kaiyu Luo laughed mercilessly, but Lu Chen was not surprised. This skill was just to let players attack teammates with ordinary attacks. If the player being controlled is a physics profession, such as the thief Ou Yibai and the gunman Silent Ram, then their ordinary attack damage is also not low.

But as a mage, Mio Shang was powerless in the game. Even if he swung his staff on Ou Yibai, he could only hit a "-1!".

"Okay, stop making trouble. Lao Ou, take Mio Shang away, so that he won't be able to run away when the boss gets angry, and he will kill him."

Lu Chen reminded him, and if he counted the time, the boss's [Mechanical Tornado Slash] was about to cool down. Unfortunately, the boss's legs were destroyed, so he could only dodge the whirlwind in place, so he could dodge it in advance.

The last skill of the boss [Decomposition and Reorganization] is actually a life-escape skill. He will explode when he is about to hang up, causing the players to be confused. Then the boss that explodes into parts will run to the fifth level, and finally reorganize next to the evil dragon and form a very disgusting double boss combination with the mechanical evil dragon.

Therefore, killing Renner boss at the fourth level is almost something that all players who play level 80 dungeons must do. There are three methods, among which the most difficult but the most stable effect is the method Lu Chen just used.

Using this method, if it fails, the whole team will withdraw back to the third floor and then re-enter the fourth floor. After entering again, the scene on the fourth floor will be refreshed, and the damaged walls will be restored to their original state. Then players can continue to work hard, and the price they pay will be at most the player responsible for seducing the boss will just hang up.

If a boss stuck in a pit cannot be blown up when using this skill, he will directly suffocate himself to death. The last 5% health does not require players to work hard.

In this situation where he almost won, Lu Chen and the other two successfully killed the boss.

"Hmph... the first kill is still ours!" Mio Shang kept looking at the first kill sign on the boss nervously. Until he killed the boss, the sign did not disappear. This means that the Norn Guild had not killed this boss yet, and the progress was behind them.

"Renner boss's first kill is meaningless." Lu Chen took the time to take a look at the live broadcast room, but what made his heart sank was that None and the other two had already entered the fifth floor!

It was obvious that the five Non and the other two just killed Dr. Renner to the residual blood and let him run away. But because of this, the five Non and the other two entered the fifth floor more than ten minutes earlier than Lu Chen.
