Benjamin glanced at the bloodstain on the ground twice, and made sure that the three lichs had been completely destroyed, before putting away the deep sea realm, turning his head, and saying to a few mages, "Gather the materials that can be used, and then return to the academy." ”

Several mages were stunned when they heard this.

“...... Do you want to return now?"

Benjamin nodded.

Seeing this, the mages naturally did not object again. There was enough food and water in their bags to continue, but if Benjamin wished to terminate the expedition, they wouldn't say anything more. So far, they've had quite a good harvest.

They cautiously stepped forward and took out their special tools to collect the remains of the undead from the explosion.

Miles suddenly came to Benjamin's side, and his face was not very good-looking.

"We can go on and explore, the world of the dead...... This is just the beginning. "Don't you want to know what's going on deeper down?"

Benjamin didn't answer immediately, but gestured to him in silence, then turned his head, urging the mages over there to move faster.

"There's no need to take those bone fragments with us, quick, we'd better get out of this place in ten minutes. ”

"Good, good ......"

Several mages felt a little strange, but they didn't ask much, but sped up the movements of their men. They collected as many skulls as they could, stored some blood in a vial, took everything with them, and flew into the air with Benjamin.

"Alright, Dean, let's go. ”

Benjamin nodded, turned around, and was about to leave the place......

However, at this moment, smoke suddenly rose from the whole forest! The white bones of the ground trembled violently, and the branches of the trees swayed from side to side as if there had been an earthquake, and the rumbling sound came from all directions!

Everyone present was stunned.

At that moment, even the water elemental spirit that had stopped on Benjamin's shoulder leaned down and let out a sharp cry.

Benjamin looked awe-inspired: "It's troublesome, I didn't escape ......"

"Lord Dean, what's going on?" the male mage asked in a bit of a panic, "Haven't those three undead been wiped out, what the hell is going on?"

"Because there are even more terrible things sleeping beneath this jungle. Benjamin said as he looked around warily, "And the fight we just had just inadvertently woken up that thing." ”

It was only after he opened up the deep sea realm that he began to notice that something was wrong.

Just as Benjamin was dripping the lich with the water elemental, he clearly felt another powerful spiritual force, which was violently transmitted towards him. Dead, gloomy, resentful...... Complex fluctuations emanated from beneath the ground, like a sea monster awakened from its slumber.

He sensed something was wrong at the time.

He mentally asked the system, and it told him that it had a very bad intuition. The runic power contained in the Deep Sea Realm seemed to alarm something, and they had better get out of here quickly.

That's why Benjamin kept urging them to move faster.

However, at this moment, no matter what was sleeping underground, it was clearly awake completely. The black smoke contained a large amount of dark elementals, as well as a dead aura similar to that of the lich, and it was used towards them at great speed. Benjamin hurriedly activated the Elemental Command Defense, forming a huge semicircular sphere to protect everyone inside.

As a result, black smoke enveloped the elemental barrier and made a loud sound, like sulfuric acid poured on a person's body.

The water element in the barrier was rapidly consumed, evaporated into nothingness by the strange power, and if it weren't for Benjamin's constant replenishment of new water elementals, it might have broken in an instant.

Although none of the mages present were good at water magic, they also mobilized their elemental affinities as much as possible to help Benjamin defend himself.

However......

"Ah——!h

A scream of pain came from their side. Everyone looked over in amazement, only to see Miles suddenly squatting on the ground with his head in his hands, his face pale and showing an extremely painful expression.

The mage didn't dare to approach, so he could only ask on the side, "What's wrong with you?"

Miles seemed to be completely unable to hear them, just holding his head in pain, unable to make any sound other than screaming.

His magic immunity field was suddenly activated, and he began to eat at himself. The system said, "Don't touch him yet, this thing is too dangerous for humans." ”

"What then?" asked Benjamin in his mind.

"It can't be helped, it's up to his own will. The system reminded, "You'd better deal with that guy from outside first, no matter what...... I have a very bad instinct that you shouldn't be here. ”

When Benjamin heard this, he looked at Miles, who was screaming incessantly, a few more times, and finally could only sigh, and summoned another blister to protect him, and did not let any mage come near him.

Then, he struggled to sense himself into the black smoke beyond the elemental barrier.

"The Living...... It shouldn't be here. ”

As soon as his mental power was tested, Benjamin was startled. Only a hoarse and low voice could be heard, as if coming from the abyss, slowly entering his mind.

Ben Jie looked around, and it seemed that he was the only one who heard this voice, and the other mages were still busy helping to maintain the enchantment, and their expressions were not abnormal.

So, he thought for a moment and said in his heart: "We don't plan to stay for long, please let us go." ”

If there is a possibility of negotiation, he does not want to have a head-on confrontation with the other party. There is a certain restraint in the world of the undead for magic, and just a few lich demons can solve it so troublesomely, and now there is another one who doesn't know how many times more powerful, and I'm afraid that I will kill myself if I fight hard.

He kind of regretted killing the three lichs.

should have left directly with people, the danger of the undead world was even more terrifying than they imagined.

"You...... Who is it? Why does it smell disgusting?" After a few moments, the voice came again, and Benjamin's heart tightened when he heard it.

Disgusted taste?

"Put away the water elemental spirits!" the system suddenly shouted.

Benjamin was stunned, and hurriedly withdrew the inexplicably excited water element spirit back into the consciousness space through spiritual connection. And a few seconds after he hid the water elemental spirit, the voice came again.

"That smell is gone......"

Benjamin hurriedly replied in his heart: "Yes, can you please let us go?"

"No, I can't. The voice became gloomy again, "You broke the rules and trespassed into the world of the dead, and I can't let you leave like this." ”

Benjamin's mood sank to rock bottom again.

"What rule? We don't know, and those who don't know are not guilty, and you can't blame us for that. There was no way, he could only mess around with the other party, while instructing the system to probe outwards and find a way out of the predicament.

"Rules are rules. The voice said slowly, "The Ghost Rift divides the world in two, one for the living and the other for the dead. Crossing the boundaries of life and death without permission, no one can escape the punishment of the rules. ”

Benjamin immediately replied, "Who are you, and what right do you have to enforce the punishment for the rules?"

"I am the spirit of bones that sleeps in this underground. The voice replied, "Every undead has a duty to remove the living who trespass here, and I must do my duty. ”

Along with its words, suddenly, the black smoke outside the barrier surged and slowly retreated, completely obscuring the external vision, but at this time, it gradually gave way to a blank path.

And along that road, everyone clearly saw that a huge bone dragon, about a few tens of meters high, was crawling towards them.
