Of course, Lin Yi would not refuse, because he urgently needed to save Ida now. However, he knew that he could not accomplish this task on his own, so the power of the three demons was of paramount importance to him.

After all, he doesn't have a better option at the moment, as long as he can defeat the Demon King, he is willing to try everything.

Moreover, he could also sense that the three old fellows should not have lied to him, after all, they were not far from death.

After receiving the energy of the three demons, Lin Yi found that his body became stronger. He felt the energy in his body boiling like boiling hot water, so he threw a punch into the ground, only to hear a loud bang and a huge pit on the ground.

The three old demons turned pale with fright, and one of them said angrily, "Human, what are you doing here?" Want to bring this place down? ”

Lin Yi smiled, put away his fists, and replied, "I just wanted to test it, but I didn't expect it to be so powerful." I'm sorry to scare the three of them. ”

His apology was insincere, but the three old demons didn't take it seriously. Anyway, they don't have much time, and it's the same if they die early or late. It's just that they hope that before they die, they can see the moment when the demon king who betrayed them was killed by Lin Yi.

"Now I'm confident I can beat that guy!" Lin Yi moved his limbs and said to the three old demons, "I'll go and kill the Demon King now, and then bring back his token for you to see." ”

Lin Yi is a man who keeps his promises.

Since the other party gave him strength, he will help the other party get things done. And destroying the Demon King is also something he must do. It's a win-win-win-win

After saying goodbye to a few old guys, Lin Yi set off again. He now felt like he could do it without relying on puppet warriors.

After a long journey, Lin Yi came to the Demon King's castle again. He felt the Demon King's icy gaze staring at him.

The other party was also a little surprised? Because Lin Yi's current strength is more than twice as strong as before.

"Human, the energy in you feels familiar to me. Did those three old guys lend you their power to deal with me? The Demon King's voice swirled in Lin Yi's mind.

Lin Yi smiled coldly and said, "You guessed right. I was entrusted by them to solve your problem. Now wash your neck and wait for me to find you. ”

The Demon King let out a burst of wild laughter and said contemptuously to Lin Yi, "You are too naïve, you think that you can defeat me with the power of the Three Sage Kings? Didn't those old guys tell you how they were defeated by me in the first place? ”

Lin Yi didn't pay attention to the Demon King's cynicism, he ran hard and galloped in the direction of the Demon King City.

The gate of the castle slowly opened, and a large number of demon army soldiers poured out of it. They brandished all kinds of weapons, let out strange screams, and rushed towards Lin Yi.

However, for Lin Yi, these demon army soldiers were nothing more than a bunch of dirty chickens and dogs. He waved his arm at will, and he brought up a series of powerful energy shockwaves, instantly shocking these demon army soldiers into the air.

Despite this, these soldiers are not afraid of death and are willing to pay any price to protect their demon king.

They got up and rushed towards Lin Yi again. In the face of these ghostly demon soldiers, a cold light flashed in Lin Yi's eyes, and he ruthlessly used more powerful power to directly shatter these demon soldiers.

Everywhere he went, there were mutilated corpses. When Lin Yi came to the gate of the Demon King City, there was no longer a living Demon King Army soldier behind him.

"Demon King, why don't you come out to fight me in person, but send these weak soldiers to your death? Don't you have the guts? Lin Yi called out to the Demon King as he walked towards the castle. However, the Demon King did not respond.

After walking for about half an hour, Lin Yi came to the hall of the Demon King City. The décor here is particularly eerie and dark, with strange shapes and terrifying patterns everywhere.

It's a place where the Demon King stays.

At this time, a figure slowly appeared in front of Lin Yi. It was a red-haired man, dressed in black armor and holding two long sharp knives in his hands.

There was a thick murderous intent in those eyes, and an evil aura was released from every pore of his hair.

Obviously, this guy is the Demon King. ”

Lin Yi was a little surprised, he didn't expect this demon king to be so young and handsome, just like a cream boy in an idol drama. However, he didn't take the demon king lightly, because the more harmless the character is, the more terrifying the strength is.

"Since you took the initiative to send it to the door yourself, then I will fulfill you." The Demon King sneered.

The next moment, the two of them started at the same time and attacked each other ferociously.

The Demon King's two sharp long knives posed a great threat to Lin Yi, because the knives were so fast that they could almost cut through the air.

Lin Yi didn't even dare to stay under the knife, because the sword qi released could cut a huge crack on the ground.

If he stood in front, he would definitely be cut in two.

However, Lin Yi is not a vegetarian either. He uses his energy to his weapons and also poses a great threat to the Demon King. Both of them were testing each other and beware of each other, and neither of them dared to show the slightest flaw. Once the opportunity is seized by the other party, it will be the result of no return.

The fight lasted a day and a night, and both men were fighting their best.

In the end, it slowly evolved into a protracted battle to see who could hold out to the end.

Because neither of them can completely defeat the other, they can only rely on this war of attrition to consume the last of each other's strength.

But there is no doubt that Lin Yi, who is a human being, naturally cannot be compared to the physical strength of the Demon King.

So when the battle lasted until the third day, Lin Yi already felt a little physically exhausted.

Can't eat, can't sleep, can't even go to the toilet.

He has to keep fighting the demon king, and he has to fight twelve points of spirit and use the strength of his whole body.

This is not something that ordinary people can do, even the demon's body will be consumed.

However, what surprised Lin Yi was that the Demon King was still so energetic, and he didn't see any tiredness at all.

"Why doesn't he feel tired? Even if he is a demon king, he can't continue to use such a powerful power! ”

Lin Yi felt a little incomprehensible. But soon, the voice of the Three Sages King came from his mind: "Silly boy, the Demon King has an energy crystal on his body, which is the source of all his energy. You must break that energy crystal first, so that the Demon King will lose! ”

Hearing the words of the Three Sage Kings, Lin Yi's eyes suddenly lit up. So that's what happened! You're going to die this time!

So, Lin Yi immediately began to look for the energy crystal on the demon king's body.

But the armor worn by the demon king didn't see any crystals at all. Lin Yi guessed that the crystal might be inside the Demon King's armor, worn close to his body.

"So I have to knock his armor off before I can find his crystal?" Lin Yi thought to himself.

Then he got into action.

After the attack, he began to adjust the focus of his attack, no longer extravagant to the Demon King, but specifically to attack his armor.

One, two, three...... The Demon King's armor began to crack.

Lin Yi was overjoyed when he saw this, and it seemed that there was hope.

However, the Demon King didn't know Lin Yi's intentions. Just laughed and said, "Human, are you stupid?" Attacking my armor doesn't make any sense to me. I still have many more sets of such armor. ”

Lin Yi ignored the Demon King's cynicism, and continued to bury his head in the attack.

Finally, he shattered the armor on the Demon King's body. And that energy crystal was indeed hanging on the demon king's neck, emitting a red light. ”

"Found you, bastard!"

Lin Yi suddenly shouted loudly, gathered the strength of his whole body, and slammed the energy towards the energy source in the Demon King's chest.

The Demon King was shocked, and he roared angrily, "Did the Three Sage Kings tell you? ”

Lin Yi just responded calmly: "You have too much nonsense. ”

Immediately after, Lin Yi's energy broke through the Demon King's defense and hit the energy crystal fiercely.

In an instant, the energy crystals turned into countless fragments. And this energy crystal is not only the source of the Demon King's energy, but also his soul habitat. In order to ensure that the soul is not disturbed by the outside world, the Demon King has transferred it to the energy crystal.

However, he still killed himself after all.

As the energy crystal broke, the Demon King's body also began to crumble.

He turned into countless black ashes and gradually disappeared into thin air.

Lin Yi knelt on the ground and raised his head to the sky and shouted: "I succeeded!" ”

The battle was indeed difficult for him, he fought hard for three days and three nights, and almost lost it.

After resting for a while, Lin Yi stood up and walked over to the remains of the Demon King's corpse.

All that's left here is a pile of cracked, discarded armor and a few fragments of broken power stones.

Lin Yi collected these fragments of energy stones and prepared to take them to the Three Sages King to prove that he had not broken his promise.

"Ding! Your clearance conditions have been completed! ”

Seeing this system prompt, Lin Yi's mood became better.

Now he can leave the simulation world at any time and return to his own world.

Before leaving, though, he had a few things to attend to.

First, he returned to the underground waterways below the town and handed over the token to the Three Sages.

The three old demons all nodded in recognition of the token that Lin Yi had brought back. Then, they hugged and laughed, and their lives came to an end. And Ada, who had been taking care of the three old guys by her side, also had a sad look on her face when she saw them die.

In order to ensure that the corpse of the old demon would not be discovered by humans, Ada directly used magic to incinerate the corpses of the three people into ashes, completely destroying the corpses.

The two then returned to the ground and ended their journey.

"Do you have to go back to the original world?" Ida looked at Lin Yi with reluctance on her face.

After getting along for so long, she and Lin Yi have become very good friends of the opposite sex.

So when Lin Yi told her that she was going back, she really hoped that Lin Yi could stay.

However, Lin Yi already had his own plans. Neither the game world here nor the human world is his original world.

Therefore, it is impossible for him to stay here for long. Eventually, he said goodbye to Ida and returned to his own world.

On the other side of the world, the fall of the Demon King has gradually calmed down the waves of war.

The passage between the game world and the human world is gradually closing, and monsters no longer have a chance to break into this world and endanger the peace of the world.

As time passed, the world gradually moved towards peace, and humanity was finally able to live in peace and contentment and live a carefree life.

Lin Yi returned to the villa in Sucheng, and his Xiaomei was still staying at home.

The moment he walked in the door, Xiaomei was ecstatic and threw herself into his arms, tears welling up, but with a smile on her face.

She had a thousand words to say to Lin Yi, and in the end, everything was contained in an affectionate kiss......

A beautiful and sweet night passed.

Early in the morning, when Xiaomei woke up, she saw a letter left by Lin Yi at the head of the bed.

Lin Yi told her in the letter that he was not from this world, and he had to leave Xiaomei and return to his own world.

Despite all the reluctance in his heart, he still hopes that Xiaomei can understand his decision.

At the same time, he left all his wealth and this villa to Xiaomei, hoping that she could live happily.
