Lin Fei underestimated the number of outer formation prohibitions.

At the beginning, the results of the scan were not five million, and after he took control of the war fortress, the formation prohibition was actually improved, which proved more and more that the war clan was extraordinary.

"Master, I also want to tell you, the outer formation is only the first layer, the war fortress has a total of three layers, the outer formation is the first layer, and then the formation hub, activate the second layer, and then the third layer!"

After refining the war fortress, Lin Fei asked the system to understand the war fortress, and the province pondered it himself, and now it seems that he is right.

"Can you turn it all on now?"

"The second layer of the hub is not a big problem, you have incorporated hundreds of masters, most of them are three-star masters and four-star masters, there are a total of ten hubs, as long as there are reasonable people who can urge them, the third layer will be in trouble!"

"What's it?" Lin Fei frowned, this news didn't sound good.

"Power Stone!"

Lin Fei knew that such a war fortress was by no means a pediatric thing, and since this was the case, there must be something to urge.

This is one of the most critical places.

"Master, you come with me!"

Controlling the war fortress, Lin Fei can move at will without any restrictions.

"This is it!"

The little devil appeared in the depths of the war fortress with Lin Fei.

Here is a huge black disk, surrounded by a heavy array of prohibitions, but unfortunately there is not much power left now.

"Look inside is the power stone!"

Following the direction that the little devil said, Lin Fei saw that ten grooves appeared on the disc. Nine of them were empty, except for one recess. There is a black stone. Lying quietly in the groove.

Lin Fei sensed it a little and felt the extraordinaryness of this energy stone. Powerful and powerful.

"It's an incredible thing!"

Lin Fei had the holy stone in his hand, but compared to this thing, there was obviously a big gap.

"This is the driving force of the war fortress, when the war fortress is normal, there should be ten grooves with inlaid energy stones, and later after the war, there is such a power stone left to maintain the war fortress!"

Lin Fei also realized that he was in big trouble.

"So, I have to go find the power stone?" Lin Fei frowned.

If it's something else. Lin Fei is really not worried, why is this thing.

Troublesome!

"I checked it just now, and the energy of this power stone is only about forty percent now, which is equivalent to 300,000 energy points, so you have to look for the energy stone again!"

"Forty percent, 300,000 energy points. Lin Fei muttered, "I don't know Sicheng, what can I do?"

Lin Fei originally thought that when the war fortress was in his hands, he would have one more top-level war weapon. If you see who is unhappy, give him a cool look and ensure that he is cool and crooked.

"It's just ordinary flying and turning on defense!"

"What about the attack?" this is what Lin Fei cares about the most.

"If you start the attack, you don't have to think about it for the time being, at most it's something else. Once or twice, the energy of the power stone will be used up, and the war fortress will become a useless weapon of war!" said the little devil coldly.

It's not an attack? It's two other times, so what's the use!

This made Lin Fei very dissatisfied. I'm not happy enough.

"Is there a way?"

Lin Fei believed that the little devil said it. There should be a way to solve it, but it is nothing more than the consumption of the demon's heart.

"There's a dumbest solution for the time being!"

This time. The imp confiscates the benefit fee.

"The stupidest way?"

The little devil smiled, "Not bad. It's just a stupid way, the power stone, is a kind of purified energy, I didn't expect it to appear in this world, it can be seen that the war clan in the master's mouth is not a person from this world, otherwise, there will never be a power stone!"

"Not from this world?" Lin Fei was still shocked.

"This is a more progressive civilization!" the little demon said, "For example, I am a product of civilization progress, and power stones are also a product of civilization!"

Lin Fei seems to understand something!

"So, my upgrade system is also a civilization, do you also know the origin of the system?"

Lin Fei didn't understand why there was a system on his body, but after listening to the words of the little devil, he suddenly understood.

Maybe the ~~~~ system is a kind of civilization.

"Master, I have no comment on this!" the little devil said coldly.

The little devil didn't say it, and Lin Fei couldn't help it.

"Then let's talk about how to get the power stone!" Lin Fei decided to get back to the topic, although he really wanted to think about the origin of the system, he had to press it down. But fortunately, there are some clues.

No hurry!

The power stone is what Lin Fei is most anxious about now!

"I build yì master, you can go and buy an energy purification furnace to purify the energy!"

Lin Fei snorted, "How many demon hearts!"

The little devil smiled, "It's still the master who knows what I think, this energy refining furnace is not so expensive, it only needs a mere five billion demon hearts!"

Burst~~

Lin Fei almost vomited blood, and pointed at the little devil, "You actually said that it was only five billion demon hearts, and you said it, at this price, I can't afford it!"

At this price, can Lin Fei not vomit blood?

Without power stones, the war fortress only has empty shelves, and it is not yet overwhelmed by everyone.

"Five billion demon hearts, it's really not much!" the little devil said seriously, "I know that the master doesn't have so many demon hearts for the time being, but he can take out a mortgage!"

Lin Fei didn't have so many demonic hearts on his body, and the words of the little devil were equivalent to asking for his own life.

"Is it okay to have a mortgage?"

"Of course!"

"Is there no other way?"

"You don't have to think about it, you can wait until you find the power stone, but I don't mind if the master chooses this, according to your human thoughts, it is estimated that it will not be long before that. The master will encounter various forces, for safety. The Energy Purification Furnace must be purchased!" the little devil smiled happily.

Lin Fei rolled his eyes.

This guy knew that he couldn't find the power stone, so he was embarrassed to say this. , Lin Fei has never seen such a shameless guy, and he knows all day long that he has a demonic heart from himself.

Lin Fei knew that he couldn't buy it.

"Count you ruthless!"

After spending all his net worth, in addition to retaining 200,000 demon hearts, Lin Fei bought the energy purification furnace.

This is a big tripod furnace.

It looked very ordinary, Lin Fei was very suspicious, is this thing worth so much? He also made himself owe a large amount of debt, and he didn't know when he would be able to pay it off, and he was in debt.

"Is this thing really okay?" Lin Fei was skeptical. I looked it up and down.

"Absolutely reliable!" the little devil stood on the big ding furnace, "Or, you try!"

"What do you try?"

"Holy Stone!"

This made Lin Fei secretly relieved that he didn't have to go out to find something else.

Lin Fei took out a storage ring, which contained 100 million low-grade holy stones, and poured it into the Dading furnace.

"Purification successful!"

"Congratulations on earning 10 power points!"

Lin Fei suspected that he had heard it wrong, and couldn't help but blurt out, "I'll go, it's only ten energy points." Is there a mistake?"

The little devil said disdainfully, "Ten energy points are not satisfied!"

"Don't you feel too little?"

"The energy point itself is a product of a more civilization, and although the holy stone is good, there is too little energy in it. You have to be satisfied with ten points, or else. How could I tell you that this is a stupid idea!"

Lin Fei really had to admit it. It's a stupid approach.

It's not cool!

Lin Fei knew what he was going to do.

It is supposed to collect a large number of holy stones and use them to exchange for power stones.

"You can sue me. How many energy points do you need to activate a war fortress once?

The little devil said with satisfaction, "You're not bad, you haven't forgotten the point, the war fortress has five functions, you listen well!"

Five functions?Lin Fei was full of joy.

"The first function belongs to the confinement function, called the war cage, unified into 100,000 energy points, as long as this function is opened, it can imprison the master!"

"Any Juggernaut?"

"Yes, any Juggernaut, even a Nine-Star Juggernaut, as long as it is locked, it will last for an hour!"

Lin Fei knew that this was used to escape for his life, and it could also be used to kill people.

"The second function, the release of war behemoths, one of 300,000 energy points, unlimited quantity, has an indestructible body, and the strength is at the five-star domination level, which can be maintained outside for an hour!"

"The third function, the War Giant, one of 500,000 energy points, has no limit on the number, has an indestructible body, and its strength is at the seven-star domination level, which can last for half an hour!"

"The fourth function, War Roar, one million energy points at a time, can release the power of the eight-star juggernaut attack!" "The fifth function, destroying the world and destroying the world, five million energy points at a time, can release the power of the nine-star juggernaut attack, and the attack range is one billion miles!"

After listening to these five ways, Lin Fei couldn't help but gasp.

Except that the first feature doesn't seem to work very well, the power of the back can be imagined.

For example, war behemoths and war giants, innate indestructible bodies, as long as there are energy points, can't they become an army?

The last two, attacking continuously, I am afraid that the eight-star master and the nine-star master will also run away, and no one can stop this attack.

In fact, this is also the reason why the war fortress became a top-of-the-line war weapon.

Back then, the war clan occupied one territory after another, and it was precisely because of this, such as the war giant beast and the war giant, with an indestructible body, that is, the eight-star master and the nine-star master could cause damage, and the rest of the people were not opponents, which was also one of the reasons for the defeat, as for the nine-star master, he was locked by the war fortress and did not dare to move forward.

This also made Lin Fei hear the importance.

A war fortress is a thing that eats energy points, like a car, without gasoline it is nothing. (To be continued......)
