The Icecrown Castle on the snow of the icefield has been rebuilt, and the once most glorious structure on the entire continent is standing again, only not as glorious as it once was. Icecrown Castle is still garrisoned by powerful evil creatures, where the Lich King's former men recuperate and wait for orders.

The busiest place in Icecrown Castle right now is the Evil Room, where the Mad Professor has been working frantically since he received orders from the Lich King, and now it's coming to an end. Dressed in a white research coat and slightly hunchbacked, the Mad Professor is a lich who has been given endless life by the Lich King, and he is here with a group of men studying the metal sent from the mechanical star.

Professor Lich Mad was sitting comfortably in his chair in the real yàn room, with his legs crossed on the table full of test-tube potions, sleeping soundly. A group of Lich researchers are still conducting assays on various metals, studying how to corrode and destroy them, and for the time being, preliminary results are available, and further assays will have to wait for the research to continue.

"Professor, Lord Lich King is here, Lord Lich King is here......" Suddenly, the door of the room was pushed open, and a lich hurriedly broke in.

Hearing the Lich King coming, the sleeping mad professor suddenly woke up and fell out of his chair, leaving test tubes and potions all over the table, some of them even reacting violently.

The crazy professor didn't care so much, and quickly got up to meet him. When he reached the door, the figure of the Lich King had already appeared, and immediately said, "Lord Lich King, waiting for your arrival!" ”

"What was the result?" The white bear just spoke, but the voice came out with an eerie and heavy feeling, and it sounded terrible.

The crazy professor didn't dare to get too close to the white bear, for fear of being frozen by the cold air around the white bear, which was a very painful feeling. The mere hearing of the white bear's voice terrified the mad professor, and he didn't dare to look directly into the white bear's ice-blue eyes. Seeing that it was the white bear who wanted to know the result of the metal, he didn't dare to slack off at the moment, and said, "Lord Lich King, the preliminary results of the metal test have been obtained. These metals are a special steel alloy with extremely high hardness and oxidation resistance, plus a heavy metal protective film on the surface, which makes it difficult to corrode with liquids......"

Seeing that the white bear was a little impatient, the crazy professor immediately said, "We have developed a strong acid that can quickly decompose metals. It's just that it will take a while to make this strong acid on a large scale. ”

"How long, is there a way to speed it up?" White Bear is indeed a little impatient, and he also wants to solve the matter of the mechanical star soon, so that the next expansion will come soon. It's just that the strength of the mechanical star is not something that one or two teams or one force can resist at all, and no one has a way to do it yet.

The player has an undead body, but the system can also spawn legions indefinitely, especially those that have no intelligence and will only take orders. It's like a mechanical legion, its own attributes are scary, plus it's a huge number, and it's a team mode operation, unless the player can resurrect in place without restrictions, otherwise he can't resist at all.

"Lord Lich King, I'll test it out to see if I can meet your requirements." The crazy professor didn't dare to meet the requirements of the white bear, so he still let the white bear see it first. If it doesn't meet the requirements and says it will be mass-produced, it will be troublesome.

The white bear didn't speak, and the crazy professor quickly asked someone to lift a solid yàn table over, put a palm-sized piece of metal into the reactor, and then took out a bottle of pale green liquid, shook it a little hard, and poured the liquid into the reactor. The strong acid liquid reacts violently with the metal immediately after contact, and the metal disappears as if it were evaporating from the human world, turning into a gray liquid mixed with the strong acid.

"For the time being, it can meet the requirements......" White Bear didn't expect this seemingly inconspicuous potion to have such strong oxidation, the steel on the robot was melted in an instant, if it was sprinkled in one piece, I am afraid it could corrode a large number of robots, with a range attack effect, "It's just that I want this strong acid to have the attribute of plague spreading, and it will corrode machinery on a large scale." ”

If a strong acid is on the metal, it will melt when it touches the metal, and it will fall to the ground and will not work. If strong acids can be given the properties of plague and can spread on a large scale, then it will be the end of the robot.

"Lord Lich King, I'm doing research on this right now, looking for a germ that can carry strong acids, and it may take a little longer!" When the crazy professor heard the white bear say this, it was fortunate that he didn't stay after completing the strong acid before, otherwise he would be in trouble now.

"The progress is faster, as for the conditions for the large-scale production of this strong acid?" The white bears have already sensed the end of the mechanical legion, and with this strong acid, they will be killed quickly.

"Lord Lich King, if you want to make this strong acid on a large scale, it's best to have rotten intestines and rotten noodles, but they ......" The two strongest hated creatures that the mad professor once researched were rotten intestines and rotten noodles, but they had already been killed by the Guards at the time, and now there are no materials to recreate them.

"I'll bring them back to life and get the materials ready." The Lich King is powerful enough to resurrect any conscious evil creature, and of course it's easy to deal with rotten guts and rotten faces.

"Lord Lich King, this ......" The mad professor quickly got out of the way and led the white bear to the place where the evil was made, which was a melting pool full of rotting corpses, and there were many evil creatures in it.

When the white bear came to the side, an ice barrier suddenly appeared under his feet, freezing the entire melting pool, reaching out, a gray power split into two, and two disgusting hateful creatures were drawn from the melting pool, which were the rotten intestines and rotten noodles that had been defeated by the white bear.

Standing on the ice above the melting pool, the White Bear poured blood, ice, and evil into them, making the two haters extremely powerful. After a frantic roar of pain, the rotten gut and rotten face became even larger, with a dark layer of gray black gas wrapped around it.

"Lord Lich King, this is ......" The Mad Professor opened his mouth wide and couldn't believe that the White Bear had strengthened the rotten intestines and rotten face, which seemed like a miracle to him.

"If you can help me destroy the Mechanical Legion, you will gain more power in the future, and even you can get a more powerful Lich body!" The White Bear turned and left, and didn't care about the rotten intestines and rotten faces, the two haters just had to hand them over to the mad professor.

The mad professor quickly followed, ignoring the rotten intestines and rotten noodles, and said, "Lord Lich King, give me another day, and I can study the strong acid plague, please believe in my ability!" ”

The white bear didn't reply, and left directly, leaving the crazy professor with a cold and terrifying back, which made him shudder.

With the strengthened rotten intestines and rotten surfaces, it is much easier to produce strong acids on a large scale, and the next step is to study the plague of strong acids, which corrode mechanical metals on a large scale.

The Rotten Intestine and the Rotten Face waited until the Lich King was gone, and the Mad Professor turned to look at them and said, "Don't look at me, if you can help the Lich King, it will be your luck, and then you may have the Lich Body and eternal life." ”

It was the first time that the Evil Room had been taken so seriously by the Lich King, and the Mad Professor didn't dare to hesitate, if he couldn't study the strong acid plague in a day, then he would be in trouble.

White Bear, who left Icecrown Castle and returned to the main city of the Natural Calamity, didn't expect things to go so smoothly, Reg's side could find someone to infiltrate the Steel Machinery City, and he could also create a strong acid plague on his side, which indicated that the end of the mechanical army was not far away. Now it's a matter of finding a way to deal with the mechanical commander on the Iron Throne, a starry giant who is even more difficult to deal with than the Moon Knight.

The biggest difficulty for players to deal with machines is that there is no aggro limit, and the machines can't count aggro at all, that is, the tank can't pull it at all. If there is a commander, then the machine will attack the easiest to kill, and will never attack the hardest tank, so it will be difficult to find a strong team to deal with the robot commanded by the mechanical commander.

After going offline, White Bear contacted Reg and explained the situation here.

"Master, I didn't expect you to be able to study even the strong acid plague, this time the mechanical legion is definitely going to die!" Hearing the White Bear say that he would be able to get the strong acid plague in one day, Reg felt that this mechanical star was no longer difficult.

"Now you're going to find a team to deal with the mechanical commander, this star giant should only be challenged by players, and it will be difficult to deal with him." White Bear didn't say that clearly, anyway, he knew that Reg knew about the Iron Throne.

"Master, don't you Heavenly Cavalry Clans take on tasks?" Reg felt a little panicked, how could it be possible that such a good mission Heavenly Rider Clans didn't want it?

"It takes a lot of time and effort to complete the task of the Iron Throne, and for the time being, the coach doesn't plan to take it, just let some people participate, so the main force is still you!" White Bear knew what the coach meant, he didn't want to waste his time on the Iron Throne, which didn't make much money. The Celestial Clans no longer need to complete the expansion follow-up quests to increase their reputation, and now they are mainly the Emperor's Cup.

Besides, it's not so easy to get through the Iron Throne, even if Reg assembles a strong team, there are a few times when he can't clear the wasteland. Since Reg had time and wanted to do the task, the coach gave it to him. The meaning of the white bear is similar to that of the coach, and you can join in the fun when the time comes, but you will not be in the mood to organize the white bear.

"Okay, Master, if there are any major tasks in the future, you will leave them to me Rege! I'm good at everything, but I rarely take on this kind of task! Passion, Reg is going to destroy the Iron Throne with a large army this time, and the mechanical commander is waiting to turn it into scrap iron! Reg was excited this time, he also knew that organizing was difficult, but he loved to do this kind of thing, and he was a good conductor and organizer in his own right.
