The cold wind is howling.

Snowflakes mixed with icy cold wind whistled across the icy plain in front of them. Countless undead roared and slowly moved forward. Behind them was a tall, pitch-black fortress. Spiky towers rose straight into the sky from both sides of the city wall, like the sharp teeth of a beast. Under the gloomy and dark sky, everything in the world seemed to be surrounded and frozen.

"roar--!"

A giant skeleton dragon spread its huge wings and flew through the sky, then landed on a cliff not far away with a "bang". It opened its mouth and let out a deafening roar. Invisible waves spread in an instant, and even the surrounding icebergs collapsed.

"Huh...successful."

Fang Zheng put his hand down and wiped the cold sweat from his forehead. Then he raised his head and looked at the scene in front of him with satisfaction.

Fang Zheng was certainly not in a 25-man team dungeon in a game. In fact, this was his "Seal". Through the intelligence hidden in the soul stone and the power of existence, Fang Zheng successfully extracted the information from the soul stone of the Lich King Arthas, used it in his own seal, and finally created such a powerful battlefield.

For Fang Zheng, this is actually not a difficult thing.

It's like making a game. No matter how powerful the modeling looks, it's meaningless because modeling is just modeling, a 3D model. If you want it to have various attributes or attack damage, you have to add command modules or write code to it. This is what Fangzheng has to do.

Fortunately, Arthas's soul stone contains the "codes" of all the Scourge units. What Fang Zheng needs to do is to use the power of existence to create these Scourge "3D models" and then input the information text in the soul stone. Since the essence of the power of existence is "existence", as long as Fang Zheng inputs this information, the power of existence will automatically "run the data" and produce an effect.

And now, for Fang Zheng, the last combat unit in his seal, Sindragosa, has been dealt with.

As for the Lich King himself, Fang Zheng did not intend to get it out, because after using the power of existence to analyze the soul stone in depth, Fang Zheng found that the Lich King Arthas himself was the core of the soul stone. The "information text" it possessed was also an astronomical number, which meant that if Fang Zheng wanted to extract it from it, the power of existence consumed would be too great. Moreover, that was the core of the soul stone. Things like the Scourge were just scraps, and they were easy to repair once an accident occurred. But if the core of the soul stone had a problem, Fang Zheng would not even know how to repair it. At that time, it would be a loss for Fang Zheng to destroy a soul stone directly.

Not only that, the most important thing is that through Feng Jue, Fang Zheng discovered a way to "use the Soul Stone in a clever way"!

You should know that when equipping a soul stone, Fang Zheng can only obtain the special effects that come with the soul stone, and if he wants to use other effects, he must activate the soul stone. This means that for Fang Zheng, the essence of the soul stone is to open a big move.

But in many cases, using a big move is too wasteful, and the Soul Stone can only be used a limited number of times.

But the seal is different.

After the experiment, Fang Zheng discovered that, although according to his idea, the soul stones would also be consumed when the seal was opened, at least it would not be consumed every time like before. On the contrary, according to Fang Zheng's calculations and his current situation, the soul stones consumed when the seal was opened once were almost equal to one percent of the power of activating the soul stone once.

This means that as long as Fang Zheng takes the energy stone and charges it randomly, he can replenish the consumed power without completely activating the entire soul stone.

In this way, Fang Zheng can not only obtain the auxiliary bonus of the soul stone, but also avoid consuming the soul stone too many times. In addition, he can pull the enemy into the small world for battle through the seal. It can be said that he kills several birds with one stone. It couldn't be better.

But other than that…

"The consumption of the power of existence is still a bit high."

Because it is not like other seals that simply isolate space, but create a small world. Therefore, Fang Zheng's seal consumes a lot of existence force. More importantly, it is not enough to release it, it needs to be maintained. And maintenance also consumes existence force. According to Fang Zheng's calculation, the existence force he has now is only enough to maintain this seal for one hour. This is the attack mode of Fang Zheng's full strength after summoning all the Scourge Legion and the Boss. Of course, if the existence force is not consumed to create these phosphorus, then the time will be even longer.

It is also a flaw that you cannot isolate yourself for as long as you want like other seals.

But think about it carefully, if you can't kill the enemy in an hour, then there seems to be no point in persisting?

That's all for now... Then what's left is... the backup energy system.

Fang Zheng glanced at the Zero Hour Lost Child in his hand and nodded. At this moment, in his hand, the Zero Hour Lost Child was already wrapped in layers of Freedom Method. And around the Zero Hour Lost Child as the core, a Freedom Method like petals was formed.

This is a combination of Fang Zheng and Tilia's free style, in which Fang Zheng's free style is responsible for storage, while Tilia's free style is responsible for transmission. Since Tilia's nature as a Red World disciple is "dedication", her free style also has the nature of transmission and dedication, and can transmit the power of existence to the maximum extent.

If we make an analogy and compare Fang Zheng's Zizai Style to a large-capacity hard drive, then Tilia's Zizai Style is a high-quality data cable used to connect the "Zero Hour Lost Child" and the "hard drive".

Because of this, the free style in Fangzheng's hand now looks like a golden lotus with white stamens, which is much more beautiful.

The Free Style in Fang Zheng's hand is divided into three layers. The outermost layer is designed to provide and consume the power of existence. The second layer is the backup energy system designed by Fang Zheng, in case of emergency. As for the middle part, it is the final trump card and prohibition.

In this way, one of Fang Zheng's sealed projects, "Icecrown Citadel", was completely completed.

The reason why it was one of them was because his next target was Masail - well, the high-level heaven was a very good choice for showing off. If Fang Zheng could create a high-level heaven in Feng Jue, then the group of people in the temple would not have the courage to come and cause trouble for him again.

I hope so.

But before that... we must test the combat effectiveness of "Icecrown Citadel".

Oh, it’s a pity that the woman was given to Shana.

Fang Zheng shook his head after retracting the seal. Ever since the battle, the woman named Ma Qionglin had lost all her domineering aura and was completely silent. She just drank alone in her boarder's house every day. By the way, she actually chose the home of a student in Fang Zheng's class as her place of residence, which made Fang Zheng speechless.

Could it be that those two guys who never listened in class are the protagonists of this world? That's a bit far-fetched.

However, since the other party was a drunkard, Fang Zheng naturally had no interest in attacking him. He could only wait for the next blind enemy to appear... Well, according to Alastor, several Red World disciples and Fire Mist Warriors, such as "Hunter", "Corpse Collector" and "Elegy Reciter", have appeared here one after another, which means that this place may have become a vortex of struggle. Maybe new Red World disciples or Fire Mist Warriors will come here after this.

We'll talk about it when the time comes.

After making the decision, Fang Zheng turned around and walked towards home.

"Welcome back, Brother."

When Fang Zheng returned to the room, the first person to greet him was Tilia, who was smiling as always. She came to Fang Zheng like a sister who respected her brother, or a gentle and virtuous wife, and then reached out to take his coat.

"I'm back."

While nodding to Tilia, Fang Zheng glanced at the entrance and then found another pair of shoes.

"Shana is here too?"

"snort!"

Hearing Fang Zheng's question, a cold snort came from the direction of the living room. Tilia chuckled, put Fang Zheng's coat away, and turned to walk towards the kitchen.

"Well, please wait for a moment, my dear brother. Dinner will be ready soon."

"OK."

Looking at the gentle and cunning smile on Tilia's face, Fang Zheng could only shrug his shoulders helplessly. Since that day, Shana and Tilia had not had any conflicts. But Tilia obviously would not let this fire mist warrior go. Basically, she would act coquettishly and show intimacy to Fang Zheng every day regardless of time, place or occasion, and she would also specifically choose to do things that Shana could not do at all.

For example, welcoming him back, getting him clothes, etc. Shana was unwilling to do such things, and she couldn't do them because of her pride. So every time when Tilia stuck to Fang Zheng, Shana had a dark face, as if she wanted to pick up a knife and hit her.

As for Tilia, she is just enjoying the feeling of "I like that you can't stand me but can't get rid of me."

Thinking of this, Fang Zheng shook his head helplessly. He certainly didn't intend to intervene in the quarrel between the two little girls. It wasn't a big problem, just a little temper. So he didn't care, but walked straight into the living room, looked at the girl in front of him and raised her hand to say hello.

"Yo, Shana."

"snort!"

Seeing Fang Zheng coming in, Shana snorted coldly and turned her head away.

It seems that this stimulation is quite serious.
