However, Li Yuan did not turn on the automatic attack mode of the arrow tower, otherwise the necromancers would have no experience to upgrade.

The first and second order necromancers require less experience to upgrade, and by noon, all ten black zombies have been promoted to the second order, and the two ranged attack corpse monks have been promoted to the third order.

It is expected that by the evening, all the newly recruited necromancy will be able to reach the third order.

The eight necromancers who had gone to explore the edge of the territory also returned, and the mysterious monster that blocked the door at three ends really disappeared, which made Li Yuan breathe a sigh of relief.

"It seems that this monster only appears at night."

Li Yuan thinks about everything.

In that case, he'll have to take advantage of this time to explore the outside.

The monsters that appear in the territory now are all first- and second-order, and it is too slow to level up by relying on them.

You'll have to go outside to find higher-level monsters.

Thinking of this, Li Yuan waved his hand and let all the dead spirits follow him towards the outside.

Li Yuan is also a third-order strength now, and it is daytime, plus there are so many necromantic protections, he feels that he can't stay in the protective shield all the time.

A mysterious monster appeared on the second day of the arrival, and who knows what else will appear later.

If it goes on like this, the protective cover disappears after seven days, and Li Yuan has no second fate except for the dog leash.

Obviously, this kind of behavior will not work for the lord.

Li Yuan led a group of necromancers to the edge of the territory, and he could still see the ravines left by the monster last night on the ground.

It was dragged out by the monster with an iron hook.

Li Yuan visually measured the depth of the ravine, and finally judged that even with the blessing of the underworld aura, they would not be able to hold out for a round under that monster.

The ravine was so deep, forty or fifty centimeters, deeper than a tractor's plow, and you can imagine how heavy the hook was.

After leaving the territory, the effect of Hades' aura disappeared, and Li Yuan obviously felt a little uncomfortable, but the necromancers still looked dead.

Li Yuan looked up at the outside of the territory, it was dry, and there seemed to be a river that was not wide in the distance, and he didn't know where it led.

On both sides of the river, there are black tombs, the small ones are only one or two meters high, and the large ones are more than ten meters, like a small hillside.

There is no need to guess, the tomb that is more than ten meters high must be full of high-level monsters, and it is not something that Li Yuan can resist at this stage.

"Today's task is to ascend to the fifth order, and after the fifth order, with the blessing of the aura of the underworld, I should be able to open the secret realm."

Li Yuan looked at the tombs in the distance and took a deep breath.

"Little ones, get to work."

At the sound of an order, more than thirty necromancers swarmed towards a black tomb.

Looking at the height of that tomb, it should be a third-order zombie inside.

Roar!

Sure enough, as the grave was opened, a dark purple zombie rushed out with more than a dozen purple zombies.

Li Yuan had previously tried to convert the Purple Zombie and Dark Purple Zombie into necromantic classes as well.

However, the system prompted him that the level of the Pool of the Underworld was not enough to be converted.

In other words, the grades of purple zombies and dark purple zombies should both exceed two stars.

So in the same realm, Li Yuan's necromancer is still very difficult to face this group of zombies.

But it's a pity that Li Yuan's realm of necromancy and zombies are not equal.

Eight of the thirty-two necromancers were fourth-order, and a few were third-order.

This kind of strength is crushing in the face of this group of strongest third-order zombies, and there is only one third-order zombie.

[Your big skeleton killed a third-order zombie, experience +100]

[Your Big Skeleton kills a third-order zombie and obtains a third-order death crystal]

……

[Your big skeleton killed eleven second-order zombies, experience +220]

[Your big skeleton kills eleven second-order zombies and obtains 11 second-order spars]

……

In less than five minutes, a third-order zombie tomb was bulldozed, and Li Yuan also gained more than three hundred experience.

It's just that this bit of experience is a drop in the bucket when it is distributed to more than thirty necromancers.

Li Yuan is not in a hurry, it will be a long time before it gets dark, and it is enough for him to develop well.

In this way, he led a group of undead spirits along the river to dig graves.

During this time, the tomb of a fourth-order zombie was also opened.

The color of the Tier 4 Zombie has been changed from dark purple to red, and it also has a Frenzy skill that greatly increases its movement and attack speed.

Li Yuan was caught off guard, and the necromantic team was almost wiped out in its hands.

"It's outrageous."

Li Yuan saw with his own eyes that this fourth-order zombie easily killed four fourth-order big skeletons with one enemy and four, which made him wonder if this zombie was a fifth-order.

More than thirty necromancers, facing one fourth-order zombie and five third-order zombies, were actually inseparable, and even at a disadvantage.

Seeing that the situation was not good, Li Yuan did two steps in three steps, and retreated into the territory without looking back.

and beckoned his subordinates to retreat as well.

A group of necromancers received an order from Lord Hades, and fought and retreated, retreated and died.

The short distance of a few hundred meters is like a moat for them.

Wait until the last necromancer is less than ten meters away from the territory, and it looks like it is about to step into the territory.

The red zombie swept its claws and killed this necromantic town in front of Li Yuan.

"Come here."

Li Yuan was so angry by this scene that he actually issued a provocation to the red zombies.

As soon as the words came out, the red zombie looked at Li Yuan, and then let out a low roar and rushed towards the territory.

"It's good to come."

Li Yuan is not surprised, as long as the red zombie dares to step into the territory, Li Yuan will call it a return.

Roar, roar, roar.

The red zombie, who didn't know that death was about to come, stepped into the territory in one step.

And the moment it stepped into the territory, the two third-order arrow towers turned their crossbows and fired wildly at the red zombies.

The attack range of the tower is 1,000 meters, and the territory range is 2,000 kilometers.

Therefore, Li Yuan specially built the arrow tower in the middle of the territory, so that its range just covered the entire territory.

Woohoo.

Sharp arrows roared towards the red zombies, each of which was as fast as the strength of a fifth-order monster.

No matter how powerful the red zombie is, after all, it is only the fourth order, and in front of the two arrow towers, it only takes seven or eight seconds to be shot directly.

The reason why it takes seven or eight seconds is that those arrows flew out of the arrow tower and flew in front of the red zombies, and it took three or four seconds.

By the fifth second, the arrows were still flying, and the red zombie was dead.

[Ding, your arrow tower killed a fourth-order zombie, experience +500]

[Ding, your arrow tower killed a fourth-order zombie and obtained 1 fourth-order death crystal]

"It's amazing."

Li Yuan looked at the red zombie with arrows stuck in his body and swallowed his saliva.

Should I say it or not, the arrow tower is the arrow tower, and it is more powerful than the necromancy.

At this time, Li Yuan's eyes were attracted by the ball of light under the red zombie, his eyes lit up, and a smile appeared on his face.

"It's shipped."
