When Li Xian arrived at Huo Yin's laboratory, Huo Yin was fully armed, his expression was highly nervous, and he looked around like a thief.

Of course, Huo Yin's so-called "fully armed" is not the traditional armor of human society, nor is it a magic weapon of super creatures, but equipment similar to a spacesuit.

Carl was by Huo Yin's side, and his spirit was also highly nervous.

As soon as he saw Li Xian, Carl looked surprised, but Huo Yin was still worried, and only breathed a sigh of relief.

"What's going on?" Li Xian asked.

"They know that I have mastered the technology of shuttling through the dimensional membrane wall, and they know that I want to continue my research, and they want to get rid of me-" Even when he was talking to Li Xian, Huo Yin still looked around, looking like he was nervous, and muttered, "I'm not afraid of death, but my research is not mature, and I haven't taught these studies to my students, so I can't die so soon!" Master Li Xian, you must save me! As you said, I will live for another twenty years, and in these twenty years, I will not only intensify my research, but I will also go to the university and teach more students—"

"Who are they?" Li Xian asked.

"I don't know who they are, but I know they can appear at any time, they come from a highly developed parallel world! I deciphered their information, they are here to kill me, they are preventing the rise of humans in the Central Axis World, there must be a conspiracy, I can't let them succeed......"

"You said that there are no super beings in the parallel world, so they should be the humans in the parallel world." Li Xian patted Huo Yin's skinny shoulder and said with a smile, "Don't worry, it's no problem to deal with the humans in the parallel world with my strength, now I will personally be your guard, and see how they still hunt you down!" ”

Li Xian also wants to meet the humans of the parallel world.

"This, this is not appropriate, Lord Li Xian, how dare I let you be my guard!" Huo Yin hurriedly said, "With so many territories and brothers under your command, it's okay for you to personally protect me for a while, but you can't protect me for twenty years!" Besides, you're going to make a great migration—"

"And what do you want me to do?" Li Xian looked at Huo Yin, who was contradicting himself, and asked.

Huo Yin scratched his head in embarrassment: "To be honest, I don't know, it's best to stop them from breaking in once and for all, to gain twenty years of development and growth time for the human beings of our Central Axis World, as long as I can live, I promise that within twenty years, I will definitely find a way to deal with them!" ”

"The Dimensional Membrane Wall is forbidden to super creatures, and I don't know how to deal with enemies from parallel worlds right now. So you're welcome, I'll be your guard for a while, and then we'll think about countermeasures after seeing those enemies. ”

"That, that wronged Lord Li Xian!" Huo Yin bowed deeply and gratefully.

Karl also followed Shi Li, and said with a look of adoration: "Lord Manjing Ghost King is really a great merciful-"

"Okay, okay," Li Xian hurriedly interrupted Carl's "sycophant" and said with a smile, "Be quiet for a while, and wait for the enemy to appear!" ”

At the moment, all three fell silent.

Huo Yin and Carl were still maintaining a high degree of tension, but Li Xian was sitting cross-legged, looking like he was recuperating with his eyes closed, but in fact, he had been paying attention to any movements around him.

After all, the enemies of the parallel world attacked through the dimensional membrane wall, and the walls and other barriers in reality were useless to them, they could appear from any corner, and Li Xian had to be careful.

An hour passed in the blink of an eye.

Most of the night passed.

It was dawn, it was dark again, and almost a day had passed.

There are no anomalies in the lab.

Li Xian was not in a hurry, he could multitask, and when he was guarding Huo Yin, his eyes were scanning the entire Central Axis World at the same time, paying attention to the mobilization of the brothers' great migration.

But Carl couldn't sit still, he was afraid that Li Xian would blame him, so he whispered to Huo Yin's ear several times and asked, "Old friend, are you sure they will come to attack you?" Could it be that you are mistaken? ”

"You know who I am, I can't lie, and my level of science means I can't be mistaken! Really, they're really going to do something to me-"

Before Huo Yin finished speaking, the air in front of him suddenly twisted like a film, and then a sharp spear passed through the "film" and stabbed at the center of his eyebrows.

"Ahh

Carl was also panicked.

However, the next moment, the tip of the spear was grabbed by Li Xian in his hand, and he pulled it hard, pulling the spear out entirely.

"Regret!" Li Xian shook his head, "The other party got rid of it in advance, otherwise it would be possible to drag him over to the other side of the dimensional membrane wall!" ”

"Thank you, Lord Li Xian, for your life-saving grace—"

Before Huo Yin's words were finished, he heard a few swishing sounds, and several sharp arrows flew out from the opposite side of the dimensional membrane wall.

Three sharp arrows were aimed at Huo Yin, one at Carl, and one at Li Xian.

Whether it is a spear or a sharp arrow, although the workmanship is exquisite, it has far surpassed the human weapons of the Central Axis World, but they are still human weapons after all, and they have no mana.

Such a sharp arrow can't hurt a super creature, and Li Xian and Carl can't even dodge.

As for the three sharp arrows that shot at Huo Yin, they were also picked up by Li Xian.

"These enemies are really good, although they are ordinary creatures, they can attack through the dimensional membrane wall!" Li Xian nodded.

He couldn't touch the dimensional membrane wall, so he couldn't catch the other party.

The other party uses a bow and arrow, and there is no way to catch it.

When he was on fire, Li Xian suddenly found that Huo Yin had just exposed the tip of a spear behind his back, and he hadn't had time to stab it out.

As long as the opponent's hand grasped the spear, Li Xian had a chance to drag the opponent out from behind the dimensional membrane wall.

This time, Li Xian seized the opportunity, and without waiting for the tip of the gun to come out, he grabbed the tip of the gun and dragged it violently while the other party had not yet let go.

"Ahh

With a scream, a figure clutching a spear was ripped out.
