Gu Huai was in those black powders in the bones of the giant rat, and when he saw the energy fluctuations, he probably knew it in his heart.

Items that can suppress the use of magic must be able to carry a large amount of magical energy.

Since the giant rat is the only mutated monster in the lower city, then it must have a secret of forbidden magic.

The first step Gu Huai did was to reduce the number of giant rats first.

Only in this way can the things that originally caused the magic to be invalid be exposed.

Holding the inconspicuous triangular black stone, Gu Huai found that its mass was very heavy.

A small piece of black stone, heavier than a small piece of gold.

The energy is contained in it, but there is no escape, it can only be imprisoned inside, unable to use it, and unable to spread.

Although it has a lot of energy, such a stone is useless.

Gu Huai didn't think so.

Since it can't be used to use magic, let it be used to disable magic.

Since magic can't be used in the lower city, let the upper city also taste the taste of forbidden magic.

"Uncle?" Zhang Wei stood with Gu Huai for a long time, felt that his feet were a little sore, and reminded him, "Do you want this stone?" You want this stone next time we'll find it. ”

"If you have one, just collect it." Gu Huai said, "Or keep it first." ”

He wanted to see what the stones would have looked like without the rats gnawing them.

After Gu Huai left, Zhang Wei didn't understand whether Gu Huai wanted to keep the stone or save the stone.

But his sister had an idea: "Didn't Uncle say it?" If you have it, just put it away? Then take a little and keep the rest. ”

Anyway, no one will pick up these broken stones.

Zhang Wei nodded, feeling that his sister was right.

Gu Huai took the triangular stone, and originally planned to go back to study and study, but he changed his mind halfway through.

He was in the lower city, many of the equipment was incomplete, and he was the only one with almost no helpers. Under such harsh conditions, I don't know how long it will take to complete the experiment.

In fact, he can also change to a better environment.

Let's say he can go to the upper city.

The tavern owner heard him say this and thought he was simply insane.

"Going uptown? Do you know how dangerous it is to go uptown? ”

He felt that Gu Huai's madness was getting worse and worse, and now it had reached the point of wishful thinking.

"Gu Huai, you are from Xiacheng, you have no identity information, you will be imprisoned and beaten to death if you go to Shangcheng. If you have identification information that shows that you are from the lower city, it is even worse, you will be directly killed. ”

The tavern owner said bitterly: "Aren't we living well in the lower city?" You see, now that we want status and status, and we want money and money, aren't we comfortable enough these days? ”

Gu Huai said: "I won't stay too long in Shangcheng this time, I'll just ask them to help me do a research, and I'll come back when I'm done." ”

The tone was as relaxed as going uptown to buy groceries.

After these days of getting along, the tavern owner knew that it was useless to persuade Gu Huai. He's just a person who doesn't listen to persuasion.

"What do you want me to help you with?"

Moreover, he knew that Gu Huai took the initiative to come to him because he had something to ask him for. If he hadn't had to help himself, he might have been on his way to the city by now.

Gu Huai: "Help me find a few reliable people, make a few robes similar to mages, and then make a few clothes for my followers, and a magic staff." ”

The tavern keeper gritted his teeth: "You're pulling me into the water." ”

Once the people in the city find out Gu Huai's true identity and ask for a thorough investigation, he will definitely be found out as a helper. They're all going to be doomed by then.

Gu Huai: "You just say don't do it, if you don't do it, I'll go find someone else." ”

"him." The tavernkeeper's face was shaking, "I've been unhappy with the people in the upper city for a long time, you must frustrate their spirit when you go up, come back and tell us their bear-like, so that we can be happy too." ”

When Gu Huai told him to use the master's robe, the tavern owner probably knew about Gu Huai's plan.

He wants to play the role of a mage outside, and go to the upper city to swindle.

You must know that although Uptown develops technology and magic, it is more about technology than magic.

True magic, on other continents, has magical powers. It can create something out of nothing, two in one life, two in three, and three in everything.

Magic is the goal that Shangcheng has always been pursuing, but it's a pity that not to mention the top magic continent, even if it is an ordinary magic city, it will not be willing to come here.

Because the Human City is a cursed place, its lower city cannot use magic.

Magicians are very particular about these and will never go to a cursed place.

This is also the reason why if Gu Huai really plays the magician, the chance of deceiving the people in Shangcheng will be very high.

"Hmm. Very good. Gu Huai said, "There is one more thing, I want to borrow your family's Zhang Wei for use." ”

The tavernkeeper clenched his fists: "He? He couldn't go. ”

The tavernkeeper knew how dangerous this was, and he couldn't let his children die.

Gu Huai's chances of success in this matter are not great, if he really lets Zhang Wei go, it will really harm him.

"Do you think that if I fail, Zhang Wei will be able to escape?" Gu Huai laughed at him, "Don't fake kindness. Besides, the plan to destroy the Upper City has already begun, and if we don't resist, everyone will die. ”

The original ending of the story was that Uptown succeeded. They succeeded in destroying the entire Lower City and occupying all of its resources.

"I'm willing to go, I'm willing to go to Dad." Zhang Wei came out from under the tavern bar, and Li San and Zhang Tan were also hiding underneath.

He was afraid that the tavern owner would not agree: "I am willing to go with my uncle, this is for us to go down to the city, this is glory, and it is a survival battle for our lower city!" ”

Zhang Wei has wanted to be a hero since he was a child. Now that the opportunity had come, he was so bent on seizing it that he didn't think about how dangerous it really was.

The tavern owner wanted to persuade, but understood that what Gu Huai said was right.

Even if they choose to survive, I'm afraid they won't last long, and sooner or later they will be caught up in the city.

"Go ahead." He closed his eyes and relented. When the child is older, it is better to let him break through. If he really died in the upper city, he would have seen a different world.

"I'll leave you behind."

The tavern owner knows who you are. It was the old man and the child who defected to Gu Huai some time ago.

Gu Huai's intention to keep that child was obvious. He left the child as a hostage to prevent the old man from talking nonsense.

He needs a helper, and the old man is a good helper, but not necessarily a trustworthy person.

In a place like Downtown, where people can be betrayed at any time, there really should be some hole cards.

Thinking of this, the tavern owner thought, Zhang Wei followed Gu Huai, did he also have the meaning of such a layer of hostages?
