The Corpse Demon King roared angrily, "If you want me to obey your servitude, it can't be! ”

Yang Xiaole snorted coldly and said, "Yes, then I'll smash the crystal nucleus where you board!" ”

As he spoke, Yang Xiaole was about to make a move.

"Wait!" The Corpse Demon King seemed to sense Yang Xiaole's intentions, and suddenly softened again.

I saw him say in a low voice: "Okay, I have changed my mind, I can obey you, do you want to sign a soul contract with me, come on!" ”

Yang Xiaole smiled and said, "That's right, I'm going to sign a soul contract with you, but I haven't practiced this spell yet, you wait!" ”

As he spoke, Yang Xiaole concentrated on cultivating the Slavery Law Seal.

The Slavery Law Seal is a high-level exercise, and the exercise method is very complex, requiring the spiritual power to be condensed into soul runes, arranged and combined into a soul contract, and finally condensed into a soul brand, which penetrates into the enemy's body.

Fortunately, Yang Xiaole's understanding was very high, and he quickly understood the principle of the enslavement seal.

And because his spiritual power can also be cultivated in a state of movement, the recovery speed is extremely fast, and he can constantly try to condense soul runes, soul contracts, and soul imprints.

As a result, it took Yang Xiaole a day to finally completely practice the Slavery Law Seal.

However, he did not directly cast the enslavement seal on the soul of the Corpse Demon King, but condensed one by one soul runes with spiritual aggression and bombarded the soul of the Corpse Demon King.

Yang Xiaole knew that the Corpse Demon King was violent and cunning, and he would definitely not obey himself easily, if he used the Slavery Law Seal to sign a soul contract with the Corpse Demon King now, he would definitely be resisted by the Corpse Demon King, and eventually cause the spell to backlash and be mentally traumatized.

Therefore, Yang Xiaole wanted to weaken the Corpse Demon King's spiritual energy to a safe level, and then use the Slavery Law Seal to sign a soul contract with him.

Seeing that Yang Xiaole dared to attack him with soul runes, the Corpse Demon King was immediately furious, and he also began to counterattack Yang Xiaole with a spiritual attack.

However, in the process of cultivating the Slavery Law Seal, Yang Xiaole has mastered the efficient use of spiritual power, even if the strength of spiritual power is temporarily inferior to that of the Corpse Demon King, he will not easily suffer in spiritual attack and defense.

As a result, the Corpse Demon King's crazy counterattack not only failed to hurt Yang Xiaole, but instead lost a lot of spiritual energy.

And Yang Xiaole can cultivate the Blood Sea Demon Skill in a state of exercise, and the recovery speed of his spiritual power is much faster than that of the Corpse Demon King, who can only use the energy crystal nucleus to slowly absorb energy.

In the end, the spiritual power of the Corpse Demon King was consumed to the bottom by Yang Xiaole, and it was not even comparable to a junior zombie.

At this time, Yang Xiaole began to cast the Servitude Law Seal, condensing a soul brand and bombarding the soul of the Corpse Demon King.

In the end, the Corpse Demon King let out a terrible scream, and Yang Xiaole successfully planted a soul imprint in the depths of his soul and was forced to become Yang Xiaole's demon pet.

"Damn boy, ah, it hurts, I know it's wrong, I mean respected master, from today onwards, I'm your pet!" After tasting the severe pain in his soul and almost losing his soul, the Corpse Demon King finally became honest.

Yang Xiaole picked up the black crystal nucleus that stored the soul of the Corpse Demon King, and said lightly: "Let all the zombies under your command surrender to me, well, you are the Corpse Demon King, I am your master, you will let your subordinates call me Lord Demon Lord!" ”

"Yes, my master!" In desperation, the Corpse Demon King had no choice but to give his subordinates an order to surrender to the Demon Lord.

"See Lord Demon!" Soon, the middle-level zombies and high-level zombies in the entire Earth Mother City fell to their knees and expressed their submission to Yang Xiaole.

Yang Xiaole flew into the sky above the Earth Mother City and announced loudly: "From today onwards, intermediate and high-level zombies are not allowed to harm people, violators will be killed immediately, in addition, you must start to clean up all the primary zombies in the Earth Mother God Kingdom and restore order in the entire country!" ”

"Yes, Lord Demon!" The zombies agreed.

Soon, the zombie army in Mother Earth City swept out in all directions and began to wipe out the primary zombies in the Earth Mother God Kingdom.

And those middle-level zombies and high-level zombies constantly surrendered to Yang Xiaole under the orders of the Corpse Demon King.

By the time he was about to leave on the seventh day, Yang Xiaole had already controlled one-tenth of the mid-level and high-level zombies in the Earth Mother God Kingdom.

And those junior zombies have also been wiped out by the zombie army under Yang Xiaole's army, and I believe that in the near future, the entire Earth Mother God Kingdom will restore order.

However, the order-maker at that time will be Yang Xiaole, the demon lord.

What's even better is that the zombie army under Yang Xiaole's command killed ordinary zombies, and it was actually counted on Yang Xiaole's head.

Although he can only get a little energy coin by killing thousands of junior zombies, he can't stop the zombie army under his command to kill quickly.

As a result, when the task was over and the system was teleporting, Yang Xiaole actually obtained more than 5,000 energy coins.

Moreover, the space ring and space bracelet in Yang Xiaole's hand were also filled with treasures looted by the zombie army.

Soon, Yang Xiaole teleported back to the public space.

At this time, it was just afternoon, and Su Ying and the others had not yet entered the space for training.

So Yang Xiaole first contacted the money leopard and sold him the treasure he brought back.

As a result, Yang Xiaole actually obtained more than 10,000 energy coins.

Yang Xiaole triumphantly teleported back to his personal space and began to use the energy coins on hand to strengthen his bloodline.

After some careful consideration, he first spent five thousand energy coins to strengthen the mid-grade fire spirit root extracted from the woman in red.

Because the Fire Dragon Palm Secret Book that Yang Xiaole obtained from Chu Ao turned out to be a top-level exercise, but he needed to have a fire-based bloodline to be able to cultivate, and Chu Ao's fire-dragon bloodline was a top-level bloodline, so Yang Xiaole couldn't strengthen it for the time being, so he had to retreat to the next best thing and strengthen the middle-grade fire spirit root that also belonged to the fire-type bloodline.

After strengthening the mid-grade fire spirit root, Yang Xiaole's attributes did not change for the time being, but he gained a fire control ability, and he found that his perception of the heat in his body became clearer.

It's a pity that that hot gas is not a real flame after all, but a heat formed after the decomposition of nutrients, so Yang Xiaole still couldn't break through to the transcendent realm immediately.

However, when Yang Xiaole took out the Fire Dragon Palm cheats and studied it carefully, he quickly practiced the Fire Dragon Palm.

I saw Yang Xiaole shouting, waving his palm and emitting a dragon-shaped flame energy, which slammed into the wall of the private space.

A loud "boom" sounded, and a big hole suddenly appeared in the wall, which was comparable to a bazooka.

Yang Xiaole nodded with satisfaction and began to consider other enhancement options again.
