The field is unfolding -

Blood lines spread like a volcano gushing blood rain to all directions, and billions of blood lines turned into a huge semi-circular canopy to envelop the highest black stone mountain.

Then the canopy expanded outward little by little, and when the canopy finally covered the earth and sky within a radius of five thousand meters, the blood line gradually faded, and then faded away.

Lu Yu stood at the foot of this black stone mountain, his hands clenched into fists, and he excitedly watched the disappearing canopy and the void merge together, which proved that the canopy was opened.

From now on, this is his territory, and you can either come in or get his permission to come in.

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

The shadow of each demon ape was so clear. In this field, there are still dozens of people who are stunned in place, not knowing what has just happened.

"Please mark the lives that are allowed to enter here and those who are expelled from here."

Lu Yu's mind appeared the method of marking. He immediately marked permission for all demon apes and Xiaoxiao in the mine, and marked expulsion for those who hunted in the realm.

In an instant, these people appeared outside the canopy.

"From now on, I don't think anyone can get in?" Lu Yu wanted to roar at the sky and vent his depression during this time.

All along, he has been trying to find a way to keep the mine from being occupied.

But he was only one person, and he couldn't stop the impact at all.

So he chose deterrence, which is not his character, so it makes him very unhappy.

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

Killing Realm, half a million health, defensive capabilities modeled after his muscles and bones.

That's two thousand bones. During this period, each person is up to 10 base damage points per attack.

Even if it is an attack by thousands of people, it will take a while.

Let alone......

The words in front of Lu Yu's eyes were still flashing.

"The Kill Domain Tower capability is turned on, and once someone attacks the field, the tower will fight back."

"The first-level killing field can open five defense towers!"

"Build a first-level defense tower: ten Star Spirit Stones, fifty Star Spirit Beads, and ten Mutant Star Spirit Beads!"

"The first-level defense tower has an attack power of 500 points, and a maximum of 3,000 health points, and its defense ability is equivalent to the bones of the domain holder."

Immediately afterwards, at the foot of the Black Stone Mountain under the realm crystal, a transparent crystal screen was suspended in front of Lu Yu.

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

On the top there is a sign for the construction of a defense tower, as well as a sign for the field upgrade.

Lu Yu 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.

Towers need to be of the same level as the realm.

In other words, the Killing Domain can only be upgraded when the Killing Domain is upgraded to Level 2.

When a field is breached, a large amount of material is required to reactivate. In the meantime, the tower's maximum health and defensive ability are the barriers that ensure that they are not shattered.

Upgrading to a Level 2 Killing Realm requires a hundred Star Spirit Stones.

"Damn, do you use Star Spirit Stones in so many places?" Lu Yu had a headache.

Only then did Lu Yu know that he was afraid that there were too many demon apes, and if the star spirit stones mined were robbed, it would be equivalent to making wedding dresses for others. Looking at it now, this is still too fucking conservative in the early stage.

There are more than a hundred demon apes, and the number of Star Spirit Stones mined now is only sixty or seventy in one night.

Upgrade the killing field and open the defense tower, all of which require star spirit stones.

"Come with me." Lu Yu saw that the sky was completely dark, changed into the clothes of the mysterious man, and then ordered all the demon apes to go with him.

Two tons of food are now in the field, if Liu Heng wants to grab it again, let him vomit blood.

One hundred and fifty demon apes moved two tons of food, and one round trip was done.

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

After the food was brought back, Lu Yu asked No. 1 to go out again with five Star Spirit Stones.

This time he was out of the way.

Anyway, he guards a mine, and with the protection of the killing field, he can let go of mining.

Then it would be better to have more demon apes.

After No. 1 received the order and left, Lu Yu stood in front of the crystal screen and familiarized himself with the other functions of the killing realm.

It's a pity that a domain is a field, and its role is defense.

Except for the description of the defense tower and the domain upgrade, Lu Yu did not find any other explanation.

For the time being, Lu Yu only thinks about upgrading the realm, and doesn't care about the rest.

They were going to join forces to attack the mine, and of course he had to defend it.

In the location designated by Liu Heng, he found a thousand Star Spirit Beads, and placed twenty Star Spirit Stones in that location.

Then he set a route in the realm crystal, and people without signs entering the realm would be automatically guided to the location where the star spirit stones were placed, and no one else could enter them.

As for who took the Star Spirit Stone, he didn't care, anyway, he did as agreed.

Now, he already had more than 1,400 Star Spirit Beads in his hands, as well as the remaining forty Star Spirit Stones and sixteen Mutant Star Spirit Beads.

Blood-burning blade, it's a must.

With so many Star Spirit Stones in his hands, he was ready to upgrade all his skills.

……

Blood-Burning Blade:

Level: 1 (Upgrade 4 times, no more upgrades.) ）

Attribute: Increases attack power by 900 points.

Special Effect: Once the attack causes the enemy to bleed, the blood of creatures below 3,500 HP will be instantly ignited, causing death.

Restriction: When using the Blood-Burning Blade, it cannot stack with the stats of other Star Soldiers. Wearing the Blood-Burning Blade, the rest of the Star Soldiers automatically gain the special effect of the Blood-Burning Blade.

……

The Burning Blood Blade was a foot long, and its entire body was blood-red, as if it were forged in blood. This is another superlative, and its ability to pass the battle is no worse than that of the Soul Gathering Hand.

It's just a dagger, but it's just right for his attack.

When not in use, wrap it up and put it on your body, and no one will see it.

Nine hundred attack power combined with other attributes, it is already nearly two thousand attack power.

……

Skill - Breath of Life:

Level: Level 1 (Upgrade 3 times, no more upgrades.) ）

Ability: When HP is above 100, increases HP recovery rate by 10 points per second.

Special Effect: If your health drops below 100 and you take heavy damage, you will have a chance to instantly regenerate your health to 500. Critical damage is 40% chance to negate the damage and restore 1,000 health.

……

"Congratulations, you have a special ability to kill and get promoted, and your skills get extra attribute bonuses. When your HP is above 100, your health regeneration rate is increased by 10 points per second! ”

"Special Effect: If your health drops below 100 and you are seriously injured, you will have a chance to instantly recover 500 HP. Takes a critical hit, with a 40% chance to negate the damage and regenerate 1,000 health. ”

……

"Good!"

A smug smile appeared on the corner of Lu Yu's mouth.

Calculated in this way, the effect of Breath of Life plus the effect of Kill Promotion is superimposed.

When he is above 100 health, his health regeneration rate is 20 points per second.

Health regeneration is faster, and the chance of natural survival is greater.

What's more, with the addition of the effect when seriously injured, he can recover a thousand health points at a time.

As for fatal damage, the two forty percent chances are added up, and anyone who has studied some math knows that this is not equal to an eighty percent chance of low damage.

Because the odds themselves are random, they are not fixed values.

But at least a 50% chance of it's also there.

Equivalent to twice, there may be one chance to negate the lethal damage and restore 2,000 health.

Watching the skills rise to the full level one by one, it was the first time he had used the Star Spirit Stone to upgrade so coolly.

"One blow of rage, the blood of the master is nine thousand nine hundred and ninety-nine, can't you still use this skill?"

Lu Yu's eyes flashed with a crazy light,

……

Rampage Strike - Instantly consumes 1,000 HP, increases Attack by 1,000 points, and stuns enemies for a second in the next hit, in addition to the HP of the attack!

……

It's a pity that Lu Yu found that these two attack skills couldn't be upgraded.

However, these skills are counted and enough to save your life.

"In two days, as long as the realm is upgraded to two levels, I will let you fight until you vomit blood."

Lu Yu said to himself, and began to organize all his things to see if he had forgotten.

At midnight, Number One returned with hundreds of demon apes.

Two hundred and fifty demon apes, calculated at the rate of ten picking six pieces a day, need to pay one Star Spirit Stone as food.

Two hundred and fifty demon apes can mine one hundred and twenty-five Star Spirit Stones in one day.

Tomorrow, the killing field can reach level two.

After arranging all this, Lu Yu remembered that he hadn't seen Xiaoxiao for several days.

Through the ability of the domain, Lu Yu found that Xiaoxiao's location was in the domain. The field encloses the mine, and also encloses the land about a kilometer outside the mine.

He forbade humans to enter, though. But the monster that was originally in this field, he didn't teleport out.

Xiaoxiao is looking for prey. It's just that now, he can only fight the three-headed demon ape alone.

But for a fifteen-year-old girl, such strength is not weak.

"She came back and gave him these ten Star Spirit Stones." Lu Yu instructed No. 1.

Number One nodded.

"Zhou Zhen said that in the mine, there are electromagnetic signals from time to time, what is the signal?"

Lu Yu closed his eyes, and everything in the realm in his mind seemed to have 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, Lu Yu's eyes opened violently, staring at the slightly northerly place in the center of the mine.

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

Just now, a subtle electric current pierced out of the void, tearing open a crack in the void, and the crack kept expanding, and at the edge of the crack, countless currents were forming an oval light gate two meters high and nearly one meter wide.
