As it turned out, the choice of the firstborn child was the right one.

In the first battle of Kyoto, even Emperor Pujun was scattered, and His Majesty the God Emperor had to use a miracle that could only be used once in his life to come, so he barely escaped from Middle Earth.

In addition, Zeus, the god king of the Olympian Sacred Mountain, died at the hands of the sixth generation chief.

The strength of the Immortal Son is not as good as that of the Chi Son, and if he stays in Kyoto, the chances of dying here are very high!

Of course, the main reason why he left the battlefield in Kyoto was that he had already captured the heart of the Demon King.

He wants to peek into the eternal secret through the heart of the Demon King.

With the heart of the Demon King, there was no need for him to help the Kong family get the support of the national fortune.

But although the heart of the demon king has become his own prisoner, how to get the eternal method has become another problem.

Swallow the Demon King directly and get the memory?

The eldest son did not dare to do this.

Because the Demon King is known as eternal, no one can say how powerful the Three Souls and Seven Spirits are. If you can't devour it, but you will be swallowed by the demon king, wouldn't that be your life?

With the cautious and cautious character of an immortal, the eldest son would never choose like this.

So the eldest son could only find a way again.

In several experiments, the eldest son tossed the seven meat and eight vegetables of the devil and was embarrassed.

So in this case, Moshan took the initiative to tell the eldest son a feasible plan.

He told the eldest son that the demon king is the demon king, and the demon good is the demon good.

If you want to live forever, you must get the soul of the demon king, not the soul of the demon good.

If you allow me to find a way to get the Three Souls and Seven Spirits out of this heart, retain my consciousness, and become a lonely soul and a wild ghost, then you will have a chance to refine the Demon King's Heart and become a candidate for the Demon King Battle.

When the time comes, if you can win the battle of the demon kings and gather all the body parts, you will become a true eternity.

Immortal.

The eldest son has cultivated to this day, and all he wants is eternity.

So after carefully thinking about Moshan's proposal, he agreed without hesitation.

After all, the demon is only the spiritual wisdom born from the heart of the demon king, and it is not the real demon king.

And he also knew that it was basically impossible to reach eternity on his own. The only feasibility is to participate in the battle of the demon king and win.

So the eldest son promised Moshan to let his soul get out of the heart, so that Moshan would retain his sanity and get the heart of the demon king himself, the best of both worlds.

But the foundation of the existence of the demon is the heart of the demon king, how easy is it to get rid of the heart of the demon king?

There are many aspects to this.

So while calculating the feasible plan, the demon shan listed one calculation formula after another, in order to get himself out of the demon king's heart.

He had been calculating for nearly two months, and in order to be able to cooperate with the Demon Zen, the eldest son even got the electronic computer in the laboratory from the surrounding countries and provided it to the Demon Shan to use.

But as of now, Moshan still hasn't come up with a definite method.

This made Changshengzi a little anxious.

When Mo Shan saw the radiant eldest son, he said lightly; "The soul is mysterious. How the soul was born and how it grows, no one has been able to say a credible theory until now. ”

"It's easy for you to want me to leave this heart, but what you want is the original memory of the Demon King, so I have to find the original remnant soul of the Demon King from this heart!"

"This, I need time, it takes a lot of time!"

The eldest son said impatiently, "We don't have time! ”

"The battle between the Demon Kings has reached its second round! The Demon King's left leg and right leg have fused, and he has begun to hunt down Zhang Jiusin! ”

"Once the Demon King fuses Zhang Jiu Sins and enters the third round of the Demon King Battle, even if I get the Demon King's heart, what then? I'll never be able to compare to the Demon King! ”

Mo Shan's heart was awe-inspiring, and he said, "The demon king is chasing and killing Zhang Jiusin? Didn't you say that Zhang Jiusin had already escaped? ”

Although he was obsessed with research during this time, he was also very concerned about the news from Middle-earth.

He knew that the Demon King's legs had fused together, and his strength had reached the level of breaking his life.

He also knew that Hwa-jin Kingdom of Middle-earth had taken over as the seventh chief and had won the bloody battle of Kyoto.

He also knew that Zhang Jiusin had escaped, and for now, the Demon King would not be able to catch Zhang Jiusin in a short period of time.

But what the eldest son just said made Mo Shan a little unable to sit still.

Zhang Jiusin couldn't stop the demon king.

Changshengzi sneered: "Just now, I got the news that the Sea of Souls has raided the Ba Min region of Middle-earth, officially launching an attack on Middle-earth. ”

"In the Nan'an shelter area, someone once saw Zhang Jiusin kill the invading mermaid and lure the demon king away."

Mo Shan's heart suddenly sudden, and then he said in a deep voice: "Has Zhang Jiusin been arrested?" ”

The eldest son snorted: "Not yet. But the Demon King has broken his life, Zhang Jiusin exposed his hiding in order to save the Nan'an Shelter Area, and it is only a matter of time before he is caught up by the Demon King! ”

"Demon goodness! I can't wait any longer! I have to refine the Demon King's heart before the Demon King fuses Zhang Jiu's sin! ”

"If you delay any longer, don't blame me for being rude!"

“……”

Mo Shan didn't care what the eldest son was saying, but remembered Zhang Jiu's sin.

The young man, who was always smiling heartily, once rejected his proposal to join forces.

He is sunny, cheerful, affectionate, and once he thinks of himself as a companion, he will be a companion for life.

It was the sea of unjust souls that he took him away from at the beginning, and it was also he who appeared in the Ten Thousand Dead Mountain in order to save himself, and the head of the demon king's left leg was bleeding.

Now, Zhang Jiusin is in trouble......

Just as he was thinking about it, he heard the eldest son say angrily: "Demon goodness! I'll give you two more days at most! If you don't succeed, I will refine you in the most brutal way! ”

"You're just a super S-class, and I'm dead! Do you understand? ”

Mo Shan suddenly turned his head and grinned: "Immortal son, it just so happens that my deduction has also come to fruition." ”

"If it goes well, there is a seventy percent chance that the Demon King's heart will inspire a hidden soul fragment. But I need your cooperation. ”

The eldest son was overjoyed, but he opened his mouth and scolded: "Old thing! I knew you already had the results! But you don't want me to refine the Demon King's heart, do you? ”

"Humph! You have to remember! I allow your three souls and seven spirits to continue to exist, and it is because of my kindness! But I don't want my kindness to be used by you as a source of pride! ”

"You're just a prisoner!"

Moshan lowered his head, his face full of fear.

The eldest son said coldly: "Okay, if you can really find the hidden memories of the Demon King, it is nothing to let go of your three souls and seven spirits. ”

"We immortals, the only purpose is eternity, that's all!"
