With the system, I take advantage of the heavens and the world

The undead world invaded again, and a large number of space passages were established in a short period of time, and countless undead creatures poured in.

Not only that, the undead who came in this time were not only numerous, but also extremely high-level.

As soon as they arrived, they immediately divided into groups.

Some stayed put, guarding the summoning circle.

Some go elsewhere to summon the local undead.

Some fought directly with the orc army.

Some burned, killed, looted and plundered resources.

This made the orcs lose sight of the other, exhausted.

The high-level orcs were furious, and dispatched masters to lead the troops to attack separately to suppress the invading army of undead.

And sent people to investigate unannounced to find out the reason for this incident.

Obviously, the army of undead was about to be wiped out, so how could there be so many army of undead suddenly, which puzzled the orc executives.

Without finding this reason, it is impossible for them to completely drive the undead out of the beastman world.

Otherwise, even if they temporarily expelled the undead, those summoning circles would continue to be established.

The orcs had no choice but to send a large number of people to find out the reason.

Tang Mo knew that the other party would send someone to search, but he was not worried.

When he did it, his hands and feet were neat and did not leave any traces.

Besides, there are a large number of undead near those summoning circles, and the orcs have no way of attacking them.

Tang Mo hid in the dark, ready to fish in troubled waters.

He came near a city, hid in the distance, and waited quietly so as not to be affected.

In the city, the orcs and the undead are at war, and the flames of war spread throughout the city.

Wherever the undead went, they burned, killed, looted, and everything that could be taken away was spared.

Even the corpses were packed and taken away, ready to go back and transform into undead for them to drive.

The orcs fought back, fighting back with fire.

A day later, the battle was over, the orcs were defeated and fled away.

The undead army drove to the next destination.

Tang Mo entered the city, and he found that the city had been razed to the ground, and the residents inside were killed and injured.

Tang Mo looked around to find the corpse of the orc, which was the purpose of his adventurous coming to the battlefield.

After the war, there should be many corpses left, which can just be picked up and transformed into undead.

As for those ordinary resources, he doesn't care.

But he was disappointed, the entire battlefield was clean and smooth, and no orc corpse was found.

It is not difficult to imagine that all the orc corpses here were taken away by the undead.

As for the corpses of the undead, such as skeletons and zombies, there are quite a few.

But these corpses have no transformation value.

They are undead themselves, and it is impossible to transform them again.

If Tang Mo wanted to find it, he could only find the corpse of the orc.

Also, those squares and cities were ransacked by the undead, leaving him nothing useful.

So, is his purpose of collecting corpses going to fail?

Tang Mo was not reconciled, in such a big world, with so many battlefields, he did not believe that the undead could be completely collected.

He came to another battlefield, this time he was a little closer, ready to sneak in, to see if he could take the opportunity to pick up the corpse.

Tang Moxuan's battlefields are all small-scale battlefields, and there are not many masters in them, and the level is not high.

In those large battlefields, there are too many masters, and the range is too wide, so it is easy to be accidentally injured.

If one is not careful, it will end in pieces.

Therefore, Tang Mo chose this small battlefield.

It is said to be a small battlefield, but there are also tens of thousands of people fighting in melee.

Tang Mo slowly approached the edge of the battlefield.

After observing for a while, he found that not only the undead were collecting the corpses, but the orcs were also collecting the corpses. They put the corpses of their compatriots who died in battle into space bags and took them away.

Tang Mo wondered, why did these orcs take away the corpse?
Could it be that they also learned undead spells, which can transform corpses into undead, and then use them to fight?
Tang Mo stopped in his tracks, and decided to follow the orc army to have a look.

See what these orcs collect corpses for.

Soon, the battle is over.

This time the undead lost and the orcs won.

After chasing and killing for a while, the orc army returned to the barracks to recuperate and adjust.

Tang Moyin was hidden in the dark, and he discovered that these orcs collected the corpses of their compatriots, gathered them in one place, and burned them all.

It turned out that the orc did not master the undead spell. After all, the body structure of the orc and the undead is very different, so it is not so easy to master.

They reclaimed the corpses only because they were afraid of being taken away by the undead.

After thinking about this, Tang Mo decided to sneak into the barracks and steal the corpse.

Tang Mo put on the Thousand Illusion Mask and turned into a kobold.

His face was old, his body was thin and weak.

He came to the barracks and told the guards that he was going to join the army.

This orc army is a motley army.

There are werewolves, kobolds, tauren and so on.

The combat power is not high, and it will not fight against the undead who are too powerful, so the danger is not great.

Therefore, Tang Mo chose it.

The guard looked at Tang Mo, but said nothing.

Now is the time of war, it is good to join the army, and the army also needs such passionate people.

But look at you, so thin, can you still carry a big knife?thought the guard.

"My lord, don't look at me as thin and small, but I have a lot of strength." Tang Mo waved his arms twice, proving his strength.

"Even if you can't go to the battlefield to kill the enemy, it's okay to help you with some chores."

"To tell you the truth, my family members were all killed by those disgusting undead, and now I am the only one left."

"What's even more exasperating is that those undead have turned my family into the same as them, and they have also become undead creatures."

"After they became undead, they in turn slaughtered our own people."

"This makes me sad. Our village was slaughtered by them."

"Whenever I think of this, my heart hurts like a knife." Tang Mo said as he shed tears.

The guard was also moved when he heard it.

"So, I beg my lord, let me enter the barracks and help you burn the bodies of those compatriots." Tang Mo said sincerely.

"So as not to be taken away by those disgusting creatures and spoil their corpses."

This reason is very reasonable, and the guard readily agreed.

What's more, the barracks really need some people who do odd jobs to lighten their burden.

So that they can concentrate on dealing with the enemy.

The guard took him to sign up and arranged for him to burn the body.

In order to effectively burn the corpses, the orcs built a simple formation.

As long as the corpse is thrown in and the formation is activated, the corpse can be burned to ashes in no time.

Tang Mo quickly mastered the formation and devoted himself to the burning work.

It turned out that this job was performed by more than a dozen people who were injured and incapacitated.

Now, after Tang Mo came, he rushed to do all the work.

The other orcs saw that Tang Mo was so enthusiastic, and the work of burning the corpse was not difficult or important, so they left it to Tang Mo to do it.

They are happy to be lazy.

After Tang Mo accepted, he worked harder.

He quietly changed the formation a few times to make the flame look bigger.

On the surface, he threw the corpses into the formation and burned them.

In secret, most of the corpses were taken into the Tower of the Undead.
