A mother husky!

Harvard doesn't believe that there is anything unsolvable. She even demolished the floating tower. This bloody castle seems to be indestructible, but there must be some way to break it, but I haven't found that way yet.

Not only the door, she even tried the windows. The windows here are also tall, with colorful patterned glass inlaid on them, a bit like Ukiyo-e style.

The glass is probably also madeina, and it won't break no matter how you smash it.

With nothing to do for the time being, she had no choice but to consider starting from the inside of the castle.But whether it is the first floor or the second floor, whether it is the hall or the room, everything looks ordinary and there is no trace at all.But the enchantment that everyone can't see is real.It can only be said that the person who designed all this at the beginning was much higher than them.

Hey, I still can't believe it!

Harvard asked the system: "Dear, do you have anything that can deal with this castle? Doesn't my mall have a barter function? Change it for me."

The system said helplessly: "This ancient castle is too weird. I haven't figured out what kind of structure it is for the time being. You can try changing a few things at random. I'll search and see... Hey, this thing is pretty cool." Interesting, give it a try."

As he said, he helped Harvard exchange three pieces of eternal spar for...a charge~front~gun?

Harvard asked it speechlessly: "You don't think this thing is useful for magic, do you?"

"This is not an ordinary strong. It comes from the plane of high-tech comprehension. It is not filled with bullets, but with fairy art. It should be useful for magic."

Harvard was speechless, it was the first time she had heard that cultivation could be high-tech, but since the system said so, let's give it a try.

So, everyone saw that the thick-skinned girl took out something that she didn't know after eating and drinking enough, and then started tumbling towards the door.Blue rays of light came out of that thing and hit the gate. Although the gate was still motionless, it was different from when they used soul power skills to test it in the past.Now that the cyan light hit the door, there would be black ripples.

What does this mean?It means that the light has an effect on the enchantment!

Everyone was overjoyed again. Although this girl was indeed a little shameless, she could really bring them hope.

After half a day of stuttering at Harvard, it seems that the energy of immortality contained in it has been exhausted.

"What should I do?" Harvard asked the system: "Can you fill it with the energy of the eternal spar?"

"No." The system said: "Immortal law and the energy of this world are completely different energy systems. I guess the protective barrier of this ancient castle has never seen such energy, so it will react. If it is replaced by orcs The energy of the planet should have been taken into consideration when it was originally designed. You can use a few pieces of eternal spar in exchange for fairy energy to fill it in."

"Can this thing be exchanged?" Harvard glanced curiously at the small bottle marked with Immortal Energy in the mall, and then was speechless for a while. A bottle of Immortal Energy is more expensive than an Immortal Gun. ?This is too good at business!

The system explained aggrievedly: "This price is not my bid, it is the bid of the system of another space plane, what can I do?"

Harvard gritted his teeth and said, "We also have to set the price of the item higher, we can't just let people kill and don't fight back!"

So she added a 0 to all the items on the shelf.

system:"……"

Is it too harsh all of a sudden?

But things belong to Harvard, so it is not easy to say much.

Harvard currently sells three kinds of things on the system mall: Hundred Flowers Nectar, Eternal Crystal, and Warcraft Crystal Core. If there are other more valuable things in the future, she will continue to add them.But for now, there are only these three things that can be sold.However, it has been a long time since these two things were put up, but no one cares about them. She is thinking about whether to spend money to buy a direct train or something like that.

She felt like a hard-working farmer uncle who sold local specialties, who worked so hard to plant them from the ground. The things were good things, but they suffered from lack of exposure.

Thinking of this, she asked the system: "How much does it cost to buy an advertising space on it?"

System: "It depends on the location of the advertisement, there are expensive ones and cheap ones."

Harvard is full of pride: "How much is the most expensive?"

As her God of Haha, she only chooses the expensive ones and not the right ones, she is rich and willful!

"One hundred million interstellar coins is almost equivalent to..." The system converted a little: "One-third of the eternal spar in your universe bag."

Harvard: "..."

What the hell, most of the eternal crystals in the universe bag are Xiao Hei's belongings, not hers!

Is your interstellar society so inflationary?This is too expensive!

She was poor and short-lived, so she had to ask again weakly: "How much is the cheapest recommended seat?"

"One hundred interstellar coins, but not much exposure."

"That one hundred interstellar coins is equivalent to how much we have?"

System: "Almost a piece of eternal spar can be sold for [-] interstellar coins, oh, now that you have raised the price, it can be sold for [-]."

However, the items sold on this kind of space plane network are all converted according to a special formula. When each system hangs items, it will strictly follow this formula, and it is not to mark as many as you want. How many.If the price is inflated, other systems will be able to see it at a glance, and naturally they will not recommend the host to buy it.

Harvard is completely unaware of this, and is still complacent about its wise move.

She spent money to buy the cheapest advertising space. Although there was little exposure, it was better than nothing.

After buying a few bottles of Immortal Energy from above, he filled his Immortal Gun with bullets, Harvard continued to chug at the gate, and even found it quite enjoyable.Just like that, after a few bottles of immortal energy were exhausted, there was a very obvious crack in the door!

But Harvard looked at her fast consumption of eternal spar, and now she has almost used up her share, and started to use Xiao Hei, and she doesn't know how long it will take to completely give up this door. Breaking through, how can I explain to Xiao Hei after I go back?This is all his belongings, it is stored here because he trusts himself, and he intends to use it to show off his might after going to the Dragon Clan.

Harvard wiped his face helplessly, forget it, let's talk about it when we can go out, at worst, give him some more youth beans as compensation.In other words, her youth beans seem to be not enough. Although the mall can be exchanged for three per day after upgrading to level three, they are all exchanged with Warcraft crystal cores. She is trapped here, and there is no The place to hunt the crystal nucleus of monsters is basically used up now, and naturally the youth beans can't be replaced, there is only a little bit that existed before, but not much.

Sigh, don't think about it so much, just break down this door first.

On the third day of her chug, this weird castle suddenly underwent a subtle change.

First, the resident in one of the rooms did not come out on the first day, and on the second and third day, he still did not come out.But according to the food he exchanged with Harvard, it was not enough to last for three days.Could it be that he has nothing to change on his body, and he plans to starve to death quietly by himself in it?

Harvard shook her head, it shouldn't be like this, she said before that if the things on her body are changed, she can swear by her soul power and pay after she goes out.In the face of life, no one will choose to let himself die, and he is not willing to exchange other things for a life.

Then the only possibility is... the occupant of that room is dead.

Sure enough, another day later, the room with the red sign on it quietly turned green without anyone noticing.This means that the room has been vacated and newcomers can move in.

Everyone pushed open the door with solemn expressions and came in to check. There was indeed no one inside, not even a corpse.

This castle is really too weird, it can eat people silently!

What made everyone panic even more was that with the mysterious disappearance of the first person, the second person also could not come out of the room. Could it be that... was also eaten by this castle?

People were panicked for a while, and they didn't even dare to enter the room to sleep. They all slept in the corridor on the second floor, lying in a row.

A few days later, someone suddenly said in amazement: "The door... the crack on the door has disappeared!"

Everyone was unbelievable, and Harvard even ran over to the gate to touch it, and the cracks on it really disappeared.

Reminiscent of the fact that people have been disappearing in the past few days, and the crack on the door has only disappeared in the past few days.

Could it be that……

Everyone's faces became extremely ugly, and for a moment they didn't know whether they were panicked or disheartened, the feeling was too complicated.

Just when all of them thought they could see the dawn of hope and have a chance to leave this ghostly place, they discovered that the cracked door had been repaired at the cost of the lives of the people inside!

How many lives do they have to fill?

I'm afraid they will all die before the door is completely broken!

But if they don't break the gate, they will be locked in this castle forever, and they will die sooner or later.

So now, they are caught in a dilemma. They want to continue to attack the door, and then worry about when it will be their turn to fill the crack in the door, and then die quietly.In other words, if you don’t attack the door, you will continue to stay in this ancient castle. Anyway, there is food here, and you won’t starve to death. There are more than [-] people, which can be regarded as a small world by itself.

All the people were divided into two camps, those who supported attacking the goal and those who supported staying behind, and they quarreled like this.

Seeing them like this, Harvard had complicated emotions, and it was the first time she was so embarrassed.
