Now, Marcus has finally shown his strength. Goo Goo can be a good shout again.

The head automatically blocked this annoying guy, and Mu Feng's gaze swept around, trying to find something helpful. A drop of lord's blood must not be able to completely transform Marcus, and before it is defeated by that demon lord, it must already be of the legendary level, and it may even be stronger than it is now. The collision of two legends-level powerhouses will leave clues for the battle in this vicinity?

This guy is a careless guy, otherwise he wouldn't have forgotten that experience note on the second floor, and he never found it. This floor should not be too clean. Especially the damage and traces caused after the battle, it is even more impossible to make up for them.

The entire fourth floor does have a lot of traces of battle. Mu Feng tried to find clues from inside. The girls also did not give up hope and were doing the same thing as Mu Feng.

Finally, the tenth summoned alchemy puppet fell under Marcus's pitch-black long knife and shattered into pieces. Waiting for someone who can fix it to reassemble it.

After dealing with these guys, Marcus didn't look like he wanted to stay at all, and began to walk towards the location where Mu Feng and the others were. It seems that it has been activated, and it will not stop until it destroys all the invading enemies!

"Summon another batch!" Before you find a way, you can't fight hard with Marcus, it's a terrifying boss at the legendary level, and if you're not careful, you may be wiped out directly!

Anyway, it was already the last battle, and everyone didn't save it, and once again summoned ten Jinying-level alchemy puppets. It seems that the powerful coercion at the beginning has been used, and the equipment on the ten puppets that appeared this time was not directly cracked by Marcus with coercion. With a lot of more attributes, they are summoned at full health, so they should be able to resist for a longer time.

In this short period of time, Mu Feng can also work with the girls to continue to find a way to defeat this boss.

As time passed, a batch of summoned alchemy puppets fell, and the summoned ones had no equipment and weapons, and they could only face Marcus's butcher's knife at the level of Yinying's boss. Mu Feng finally discovered something special on the fourth floor!

The battle between the two legendary-level bosses should be earth-shattering, and Marcus's body should not be so intact. The demon lord who defeated it should have also taken a trick!

On the roof above the fourth floor, there were many red energy crystals hanging from it. They are like chandeliers, illuminating the entire four floors with red light.

It was these energy crystals that made Mu Feng feel a trace of doubt, although there were many energy crystals, they were not so wasteful. Moreover, the hanging energy crystal is also the same as the one installed on the chest of the alchemy puppet, which has no beauty. The red light shone on Marcus, who was fighting, as if he had been absorbed by the pitch-black armor......

I see! After seeing those hanging crystals, Mu Feng figured it out a little, and now he is even more convinced!

"Whoever can hit the crystals above, attack those crystals with all your might!" Mu Feng ordered the girls. Everyone immediately took action, like Qin Shuang, Lily and others, and they all began to hit the nearly thousand hanging red energy crystals.

Mu Feng was not idle, in addition to the dark slash with a long-range attack, he also sent out a ball ball!

Each moment the Dark Crystal has 5000 HP, which is not too much, but not too little. It's difficult to want a dozen large pieces, and if you want to do a single point, it's basically a spike.

The machine-gun fire of the ball was just enough to hit a large area, and basically all the ones within the range fell before the machine gun fire was over. Two homing missiles are also range explosions, enough to destroy one piece.

On the contrary, one ball can withstand two people.

After finding this method, everyone is not afraid of the consumption of alchemy puppets, as long as they are gone, they will summon them, and they must block Marcus's attack. As if to confirm Mu Feng's guess, after the energy crystals began to decrease, Marcus's offensive seemed to have weakened, and it was not as powerful as before.

"No, you can't do that!" Professor Goo, who had been observing everything in the general control room, also found out that something was wrong, it turned out that when the demon lord was leaving, he let himself make more energy crystals and hang them on it not to look good! How can this be good, it seems that Mu Feng and they have found the easiest way to kill Marcus.

After thinking about it, Gollum finally reluctantly sent a signal for help to the Demon Legion.

"It works!" Seeing the changes in Marcus is undoubtedly the happiest thing. Everyone worked harder, and finally killed all the energy crystals above the alchemy puppet before it was consumed.

"Click...... "With only two energy crystals left in his head, Marcus, who needs a lot ......of energy to run, has difficulty even moving around now......

"Leave it alone, go straight to the fifth floor!" Time is running out, and everyone must hurry. Marcus is no longer a threat, so let's hurry up and find Gollum and get the core materials for the production of the real alchemy puppet.

Since Gollum can learn to make and repair alchemy golems as a demon scientist, it proves that those materials must be in his hands!

Rushing to the top floor, this is much smaller than the space below. In the general control room, Goo Gu is trying to hide something.

"Don't, don't come here!" Unexpectedly, before the things were hidden, Mu Feng and the others came in, and Gu Gu was very scared.

"What are you hiding, hurry up and take it out!" Mu Feng didn't bother to talk to Gu Gu ink, wanting to get the core information of the alchemy puppet as soon as possible.

"No, I'm not going to let you get it." Seeing that he couldn't hide it anymore, Goo wanted to tear up the information. But who is Mu Feng, he shot with the girls, and almost killed it in seconds.

That's right, unlike its brother who has the quality of a boss, Gollum's health is only 200,000, and everyone shoots together, and they are properly killed in seconds!

By the time Gollum's corpse fell to the ground, the thing it had hidden behind it was finally revealed. Sure enough, it was a somewhat worn codex!

Pick up this thing, Mu Feng immediately received a prompt message from the system, the task has been completed, please quickly hand over the core information of the alchemy puppet to Teresa in the main city of the elves!

"Mission accomplished, let's go!" Now that the mission has been completed, everyone naturally does not need to stay in this dangerous place anymore, and immediately uses Hearthstone to return to Sky City. It took more than ten minutes for a large number of demons to arrive and take over the mobile castle again. But seeing all the destroyed alchemy puppets or the corpses of Dr. Goo, those demons could only let out a senseless roar. The real enemy, Mu Feng, had already safely returned to the area controlled by the races of the Skyrim Continent. Even through the portal of Sky City, he has come to the main city of elves!

According to the usual procedure, Mu Feng easily entered the Elven King's Palace by relying on the token that Teresa had given him before. After only ten minutes of waiting, the elven queen appeared.

Dressed in a pale cyan robe, Teresa seemed to have just taken a bath, exuding a fresh and elegant atmosphere. It's been a while since she took over as queen, and Teresa has begun to unconsciously possess the majesty of the queen. With her original fresh temperament, it is even more attractive and charming.

"Melancholy wind, you must have completed your mission, right?" Seeing the confident smile on Mu Feng's face, Teresa seemed to have guessed the result. Mu Feng really didn't disappoint her, and together with his companions, he completed the almost impossible task!

"Fortunately, I didn't lose my life!" The things that Mu Feng wanted to hand over to Teresa had a lot of things besides the core information. For example, the Codex of an Ancient Mage, the special workbench for alchemy golems, and so on.

"There are so many good things? I've got to talk to those guys and revisit your rewards! "Obviously, what Mu Feng gave Teresa was far more than she originally expected.

"The original reward is no longer worthy of you, melancholy wind. Please give me some time, and I will definitely find a way to give you and your companion a satisfactory answer! Teresa was very excited to receive those things, and left for the first time without getting together with Mu Feng and Xiaoxi. It should be through the teleportation array to discuss Mu Feng's reward with the leaders of other races.
