Wang Kai's worries are obviously unnecessary. Book Network

The moment the Divine Spirit Advanced Pill was thrown out, the Demon King immediately turned his tall body and chased in the direction of the pill's flight, completely ignoring the enemy who was still rolling underground.

The red elixir flashed with a beautiful halo in everyone's eyes, and flew like a rainbow towards the top of the fireball not far away.

With a whirring sound, the Demon King had already quickly chased after the flying elixir, and he was about to collide with the fireball!

"Fireball, protect the elixir." Wang Kai lay on the ground and ordered loudly.

He knew the preciousness of this elixir, although he didn't know how to use it yet, but with the boss being so nervous about it, I was afraid that its value would be comparable to that of an artifact!

When the fireball received his order, he immediately raised his head, opened his bloody mouth, and with a fierce force of his limbs, his entire body jumped into the air!

Because it has no hands, it can only use its mouth to receive the pill.

Everyone looked at the Demon King and the fireball with their eyes, and rushed towards the pill that was still flying in the air at the same time, but the current situation was not optimistic.

Because the speed of the Demon Evil King is faster, its body is also big, and it is two or three meters to step out in one step, and it only took three steps to rush to the bottom of the elixir, and immediately handed the big axe to the left hand, and stretched out its right hand to grab the elixir in the air.

Oops!

Wang Kai was shocked, and secretly hated that he had used too little force when he threw out the elixir, and he actually let the boss run to the position first.

Just as everyone shook their heads and sighed, ready to watch the Demon Evil King grasp the pill in their hands, a ball of fire suddenly lit up!

Jumping up in mid-air towards the elixir, seeing that it had lost the opportunity to get the elixir, a red pillar of fire suddenly erupted from its big mouth, directly hitting the elixir that was about to fall into the hands of the Demon King.

With a pop, after the pill was hit by the pillar of fire, it seemed to be pulled by a long thread, and miraculously fell down quickly, dodging the giant palm stretched out by the Demon King, and quickly flew into the mouth of the fireball...

Ao Moo!

Seeing that the treasure that was about to be recovered was snatched away in front of his eyes again, the Demon King roared angrily, and continued to chase forward with his axe.

But this time, it has no way to recover its lost treasure...

The red elixir was wrapped in a small ball of flames, and the fire flashed in mid-air, and it flew into the mouth of the fireball like a meteor!

Wang Kai sat on the ground, and waited until the moment when the pill flew into the mouth of the fireball, and then his heart could be regarded as settling down.

But before he could stand up and continue to give commands to the fireball, an even more strange situation suddenly appeared on the field!

After the Divine Spirit Advanced Pill flew into the fireball mouth, it had not yet jumped up in the air before it landed, and its entire body actually floated in mid-air, and it never fell for a long time!

What's even more strange is that the fireball's body was in the air, and it was immediately enveloped by a layer of demonic red light, and it kept struggling in this layer of red light, but it couldn't break free!

Ding dong... System: Player's Death of God, your pet Red Flame Beast lacks advanced materials, and cannot be advanced at this time, please put in the correct materials and confirm again.

With the prompt of the system, a golden light flashed in front of his eyes, and a system selection panel appeared!

The sudden system prompt suddenly made Wang Kai confused.

"Fireball Advanced?" He was overwhelmed by the system prompt, but a large advanced material panel popped up in front of him, which made him even more confused!

In the center of this golden panel, a huge giant beast is depicted, with a dragon's head and a lion's mouth, two horns and four legs, a unicorn-like body, dragging a long snake tail, and its whole body is wrapped in a blue-white flame.

Isn't that what a fireball looks like?

Wang Kai understood that this panel was the system interface for the advanced use of fireballs.

Underneath the drawing of the fireball, there are five blank boxes, each with a large character written in it, which are metal, wood, water, fire, and earth!

"Could this be the selection of advanced attributes for the fireball?" Wang Kai didn't understand even more, the fireball has attributes, it was born with a fire system, how can it still choose attributes now when it advances?

He was still thinking about it, but the Demon King on the field was already frozen.

Ever since the fireball's big mouth swallowed the Divine Spirit Advanced Pill, the Demon Demon King stared blankly at the fireball shrouded in red light in mid-air, holding the big axe in both hands and never moving again!

There was a look of sadness in its blood-red bull eyes.

Everyone kept staring at the situation on the field, and they all saw that the boss didn't move!

Such a good opportunity, of course, the king of the world can't let go, he hurriedly issued an order, let the MT regiment take all the fighters, quietly re-surround the boss...

Come on!

After all the MT was in place, before the Demon King could react, all of them were already holding their shields high and rushing towards it!

Ao Moo! With the Demon King roaring, he swung his axe and once again engaged in a fierce fight with the players...

Outside the warrior encirclement, countless gorgeous long-range attack skills were all released again, flying far away towards the huge body in the middle!

Now that the Demon King's transformation ultimate has been used, all players don't have to worry about being killed by it in seconds, seeing that its health has been reduced to 47%, everyone's enthusiasm has risen again!

The battle on the field was fierce, but Wang Kai on the side was miserable by the panel that popped up by the system.

He didn't know what materials should be placed in these five boxes, and he didn't dare to close the panel.

Because at the bottom of the panel, there is an explanation where you choose to quit, after the pet beast gives up the advancement, the elixir used will not be returned!

Nima, what a cheat.

Wang Kai has never been exposed to such things as pet advancement, and now he is even more confused.

Since withdrawing would also lose this elixir, he decided to try anything anyway, anyway, there were a lot of strange things in his package.

He immediately opened the package and searched the bag for such things.

At the first glance, he saw the Red Flame Divine Fire Pill bought from the vicissitudes of the world, this thing was burst by the Red Flame Demon Beast, it should have something to do with the advancement of the fireball, right?

Wang Kai guessed, put the Red Flame Divine Fire Pill into the box with the word fire written on it, and tried to confirm it.

Ding dong... System: Player's Death of God, the items you use are lower than the requirements of the Red Flame Beast's advancement, please choose a higher level material!

There is a door!

When Wang Kai heard the prompt of the system, he immediately became excited!

Although it was only an experiment, the system did not say that the materials were misplaced, but only that it was lower than what was needed to advance to the fireball.

That means that things like the Red Flame Divine Fire Pill are indeed available for advanced pets, and as for the system saying that this material is lower than the advanced needs, this is the crux of the problem!

Although the first experiment failed, it was a little bit of a situation that he finally figured out.

The Red Flame Divine Fire Pill cannot make the fireball advanced, which can only mean that this material is a required item to advance to the epic level.
