The Truth Of Electromagnetism 

The field is unfolding-

Bloodlines spread around like blood rain spewing from volcanoes. Hundreds of millions of bloodlines turned into a huge semicircular sky curtain to cover the highest Blackstone Mountain.

Then the sky curtain expanded outward little by little. When the sky curtain finally enveloped the earth and the sky with a radius of 5,000 meters, the bloodline gradually faded and then faded away.

Liu Hai stood at the foot of the Blackstone Mountain. His hands were tightly clenched into fists and he watched excitedly as the disappearing sky curtain merged with the void, which proved that the sky curtain was open.

From now on, this is his territory. Either they rush in or they can only enter with his permission.

In his mind, he could see every place in the sky curtain.

The shadow of each demon ape is so clear. In this field, there are still dozens of people stunned, don't know what happened just now.

"Please mark the lives allowed to enter and be expelled."

Liu Hai's mind came up with the method of marking. He immediately marked permission for all demon ape and Xiao xiao in the mine according to method, and eviction for those who hunted within the field.

In a flash, these people appeared outside the sky curtain.

"From now on, I think who can attack?" Liu Hai wants to scream at the sky and vent his depression during this period of time.

For a long time, he has been trying to keep the mine from being occupied by others.

But he was only one person and could not resist the impact.

So he chose deterrence, which is not his character, so he was very unhappy.

But now, he doesn't need deterrence at all.

Killing field, 500,000 points of life value, defense capability based on his bones and muscles.

That is 2,000 points of bones and muscles. During this period, each person's attack is at most 10 basic damage points.

Even if thousands of people attack, it will take some time.

Besides...

Liu Hai's words are still flashing in front of him.

"The ability of the defense tower in the killing field is on. Once someone attacks the field, the defense tower will fight back."

"Five defense towers can be opened in the level 1 killing field!"

"Build a level 1 defense tower: 10 star spirit stone, 50 demon spirit bead, and 10 mutant demon spirit bead!"

"The level 1 defense tower has 500 attack points and a life limit of 3,000 points. Its defense capability is equivalent to the muscles and bones of the field holder."

Then, at the foot of Blackstone Mountain under the field crystal, a transparent crystal screen was suspended in front of Liu Hai.

This crystal screen is one meter high and two meters wide.

There are signs of defense tower construction and field upgrade on it.

Liu Hai tried to touch the construction sign on the screen with his finger, and immediately all the materials needed for the construction and the location to be built appeared.

The level of the defense tower needs to be the same as that of the field.

In other words, only when the killing field rises to level 2 can the defense tower be upgraded.

When the field is broken, a large amount of materials are needed to reactivate. In the meantime, the life limit and defense capability of the defense tower are the barriers to ensure that it will not be broken.

Upgrading to level 2 killing field requires 100 star spirit stone.

"do you use star spirit stone in so many places?"

Liu Hai realized this fucking early stage is still too conservative. He didn't ask the demon apes to mine many star spirit stone before.

More than 100 demon ape, now the number of star spirit stone mined is only 60 or 70 a night.

Upgrade the killing field, open the defense tower, all need star spirit stone.

"Follow me." Liu Hai saw that it was completely dark, changed into the clothes of the mysterious man, and then ordered all demon ape to go with him.

Two tons of food now in the field, Liu Heng wants to rob again, let him vomit blood.

One hundred and fifty demon apes carry two tons of food, it is easy and fast.

Two tons of food have been accumulated in the center of the mine. As long as the killing area is not broken, he can support it for a long time.

After the food was brought back, Liu Hai asked Number One to go out again with five star spirit stones.

Anyway, he is guarding a mine and has the protection of killing areas. He can let go of mining.

Then some more demon ape would be better.

After Number One was ordered to leave, Liu Hai stood in front of the crystal screen and was familiar with other functions in the killing field.

Unfortunately, the field is the field and its function is defense.

Liu Hai did not find any other explanation except the explanation of defense tower and domain upgrade.

For the time being, Liu Hai only wants to upgrade the field, leaving the rest behind.

They will attack the mine together, of course, he will hold on.

In the designated position, he found one thousand demon spirit bead, in that position, put 20 star spirit stone.

Then he set a route in the field crystal. Unmarked people enter the field. No matter from which direction they enter, they will be automatically guided to the position where the star spirit stone is placed. No one can enter other places again.

As for who took the star spirit stone, he did it as agreed.

Now, he has more than 1,400 demon spirit beads in his hand, and the remaining 40 star spirit stones and 16 mutant demon spirit beads.

Blade of burning blood, this is a must.

With so many star spirit stones in his hand, he is ready to upgrade all his skills.

… …

Blade of burning blood:

Level: 1 (upgrade four times, no more upgrade.)

Attribute: Increases attack power by 900 points.

Special Effect: Once the attack causes the enemy to bleed, the blood of creatures with less than 3,500 points of life value will be ignited instantly, causing death.

Restriction: When using the blade of burning blood, it cannot overlap with other demon weapons properties. Wear blade of burning blood, and the rest of demon weapons automatically get the special effect of blade of burning blood.

BLADE OF BURNING BLOOD is one foot long and red as blood cast. the ability to fight is no worse than gathering soul hand.

This is just a dagger, but it is just suitable for his attack.

When not in use, it will be wrapped up and put on the body, and no one will see it.

900 attack power plus other attributes is already nearly 2,000 attack power.

Skill-Life Breathing:

Level: Level 1 (upgrade three times, no more upgrade.)

Ability: When the life value is higher than 100, the life recovery speed will be increased by 10 points per second.

Special Effect: If the life value drops below 100 and is seriously injured, there will be a certain chance to instantly restore life to 500 points. Fatal damage, 40% chance to offset the damage, restore 1,000 life.

"Congratulations, you have a special ability killing promotion, skill gain additional attribute bonus. When the life value is higher than 100, the life recovery speed will be increased by 10 points per second!"

[Special Effect: If the life value drops below 100 and is seriously injured, there will be a certain chance to instantly restore 500 points of life. If you suffer a fatal injury, you have a 40% chance of offsetting the damage and restoring 1,000 lives. "

"Very good!"

Liu Hai smiled.

In this way, the effect of life-breath plus the effect of killing promotion is superimposed.

When he has more than 100 points of life value, the recovery speed of health values per second is 20 points per second.

The speed of life recovery is accelerated and the probability of natural survival is greater.

More importantly, he can restore 1,000 points of life value at a time by adding up the effects of serious injuries.

However, if he gets fatal injuries, the two 40% chances add up. Anyone who has studied some mathematics knows that this does not mean an 80% chance of eliminating injuries.

Because the probability itself is random, not a fixed value.

But there is at least a 50% chance.

This is equivalent to two times, and there may be one chance to offset the fatal damage and restore 2,000 lives.

Watching his skills rise to full level one by one, he was so happy.

Liu Hai's eyes gleamed wildly,

Outbreak Strike-Instantly consumes 1,000 points of life value, increases attack power by 1,000 points, and in the next hit, besides causing attack damage to the enemy, it will also cause dizziness for one second!

Unfortunately, Liu Hai found that these two attack skills cannot be upgraded.

However, these skills are enough to save his life.

"In two days, as long as the field is raised to level 2, I will let you vomit blood."

Liu Hai said to himself and began to sort out all his things to see if he had forgotten anything.

At midnight, number one returned with hundreds of demon ape.

Two hundred and fifty demon apes, calculated at the rate, need to pay a star spirit stone as food.

Two hundred and fifty demon apes will produce 125 star spirit stone a day.

Tomorrow, the killing area will reach level 2.

It was not until all this was arranged that Liu Hai remembered that he had not seen Xiao Xiao for several days.

Through the ability of the field, Liu Hai found that Xiao Xiao's position is in the field. The field encircles the mine and also encircles the land about 1,000 meters away from the mine.

Although he banned human beings from entering. But he did not send out the monsters that were already in this field.

Xiao Xiao is looking for prey. Only now, she can fight against three demon ape.

However, for a 15-year-old girl, such strength is no longer weak.

"When she comes back, give him the ten star spirit stone." Liu Hai ordered number one.

"Zhou Zhen said that in mines, electromagnetic signals appear from time to time. What signals are they?"

Liu Hai closed his eyes and everything in his mind seemed to become a huge sand table in front of him.

He was watching every corner, hoping to see where the signal was.

At one o'clock in the morning, Liu Hai's eyes opened fiercely, staring at the place slightly north of the center of the mine.

In the huge sand table in his mind, there was a low-lying flat ground.

Just now, there, a slight current came out of the void and tore open a crack in the void. The crack kept expanding. At the edge of the crack, countless currents were forming an oval light gate two meters high and nearly one meter wide.
