After all, he is behind the scenes and will not suffer any loss.

But now,

The stupid teammates in the Anti-Demon League actually sold him out!

Even if he publicly stood up and claimed that it had nothing to do with him, and stated that he would not participate in the anti-demon alliance's coalition forces, I'm afraid Tang Xiaofan would not believe him and would find a way to kill him.

That is to say,

He was tied to the chariot of the Anti-Demon League.

If he doesn't eliminate Tang Xiaofan and tear down the black technology castle, sooner or later Tang Xiaofan will come to settle accounts with him.

He had no choice! "It's possible that he wasn't a stupid teammate!"

"Those top castle lords of the Anti-Demon Alliance are so damn insidious!"

"If they were the ones who exposed me, then they were deliberately tying me to them to prevent me from running away. I must join them in besieging the Black Technology Castle!"

"Their idea is, if we die, we die together, if we live, we live together."

"Damn it!"

"That's cruel! I'll remember you!"

The young man spat angrily and cursed with a sullen face.

After a long time, he looked up at the dim sky outside and said to himself: "I have to do it anyway. I will set off for the forest tomorrow!"

He has more than dozens of dark dragons in total. He can leave ten commander-level dark dragons to guard the house and take the rest with him.

He tried his best!

The Black Technology Castle must be torn down! Only when the Black Technology Castle is reduced to ruins will he not have to worry about Tang Xiaofan's revenge in the future.

Otherwise, he wouldn't even dare to stay in Bolili Heights for long.

Because this place is too close to the forest.

Only a little over a thousand kilometers.

With the speed of the dark dragon under his command, it can run back and forth in one day. If it were Tang Xiaofan's demon, it would probably be able to reach the gate of his castle within a day.

"Destroy Tang Xiaofan's black technology castle,"

"Even if it means eliminating the biggest threat!"

"From now on, I will not only be able to rule the Boliri Heights, but I will also be able to fight my way into the forest."

The young man took a deep breath.

For a better future, he must give it a try!

Black technology castle,

Tang Xiaofan did not pay attention to the lively world chat channel, but looked at the remaining four drawings in his hand.

These four drawings are all drawings for the evolution of human arms.

The difference is that three of them are low-level troop evolution drawings, and one is a high-level troop evolution drawing.

[Rare Evolution Blueprint (Advanced)]

[Effect: can help castle soldiers achieve bloodline evolution and improve growth potential]

[Special effect: There is a very low probability of achieving bloodline super evolution. ]

[Special reminder: The higher the bloodline level of a soldier, the lower the success rate of evolution. Castle lords must consider carefully before using the soldier evolution blueprint!]

"Bloodline super evolution?"

"A higher level of evolution?"

Tang Xiaofan was a little surprised. The army evolution blueprints he had used before should only be advanced evolution blueprints.

"Unfortunately, the chance of super evolution is extremely low,"

Tang Xiaofan shook his head. If there were multiple blueprints for the evolution of advanced soldiers, there was a possibility of encountering a super evolution event. It could be said that this would only be possible if he was lucky enough to have a burst of luck.

"This is a blueprint for the evolution of advanced arms,"

"One is the one that was dropped by the level 21 Skeleton King!"

Tang Xiaofan was very sure.

Because generally speaking, the stronger the enemy is, the better the items will be . And vice versa.

The most powerful undead creature in the Tomb of Bones is the Level 21 Skeleton King.

And after the Skeleton King dies, there is also a hint that the blueprint will be revealed.

Obviously it should be this one.

"An advanced evolutionary blueprint,"

“Who will use it?”

Tang Xiaofan looked at the six-winged angel Tiga, the great elf Monica, Zhan Yi, and Zhan Er in turn.

Honestly, he had too many options.

He wanted to hand over the evolutionary drawings to every backbone.

Let them all evolve, but because there are too many choices,

He found it difficult to decide who to give the evolution blueprint to, because there were too few evolution blueprints, only four in total, and three of them were low-level evolution blueprints.

Finally, he thought for a long time.

The candidates were decided, Zhan Yi and Zhan Er, two warriors who had followed him for a long time. They had been fighting tirelessly on the front line from the very beginning, and their position in the warrior team was very crucial.

The first battle was already at level 21, and the second battle was at the peak of level 20.

Therefore, Tang Xiaofan gave the advanced evolution blueprint to Zhan Er, and the two low-level evolution blueprints to Zhan Yi.

Tang Xiaofan said to the first player: "Take these two evolution blueprints. Use the advanced evolution blueprint first. It would be best if you can succeed in one try!"

"Praise your almighty Lord!"

"I will definitely not let you down!"

Zhan Er saluted Tang Xiaofan solemnly, then walked to the side of the farmer's factory under the gaze of everyone, and began his own evolutionary journey at the place where he was summoned.

Next to the farmer's factory, a soft holy light emanated from the walls of the farmer's factory, enveloping Zhan Er. His heart became extremely peaceful and tranquil, undisturbed by external things and unaffected by the fluctuations in his heart.

A moment later,

The advanced troop evolution blueprint dissipated from his hand and then turned into a dazzling ball of light.

Zhan Er's perfect figure was vaguely visible at the beginning, but finally became completely invisible and was completely covered by the ball of light.

"I hope that the second battle can be successful in one go!"

Tang Xiaofan muttered to himself, there are only four blueprints for the evolution of troops.

There is one high-level evolution blueprint and three low-level evolution blueprints. If Zhan Er succeeds directly after using the high-level evolution blueprint, then the remaining three low-level evolution blueprints can be given to Zhan Yi to use.

Maybe in the end, both of them will be able to achieve bloodline evolution.

Of course, this is the most ideal situation and what Tang Xiaofan is most looking forward to.

At least one person must succeed. If Zhan Er fails to use four evolution drawings in a row, Tang Xiaofan will probably vomit blood.

"Advanced Evolution Blueprints,"

"Special effect has a chance to achieve super evolution!"

Tang Xiaofan really wanted to know what this super evolution was. Was it to evolve into a more powerful martial art with a higher growth potential limit? "If nothing unexpected happens, this should be super evolution!"

"What a pity,"

"The probability of achieving bloodline super evolution is extremely low."

"I'm afraid there's no need to expect it this time. When more advanced evolution blueprints are revealed in the future, I can try my luck!"

Tang Xiaofan shook his head. There was only one advanced evolution blueprint, and the probability was extremely low.

If Zhan Er could be lucky enough to achieve super evolution, he would probably laugh out loud.

While Tang Xiaofan was waiting for the end of the second evolution, he noticed that a friend had sent him a message.

When I opened it, I saw a little loli from the underground world.

The message from the little girl was: "Big Brother, the Elf Sister is here in my castle again! She was very happy to hear that we are willing to trade equipment with her!"

That dark elf? Tang Xiaofan looked up at the sky.

There was a blood moon in the sky, and the whole earth was shrouded in darkness.
