Unfortunately, a black crystal couldn't completely satisfy Francis's needs.
But after all, it was a good start, he had a deeper understanding of his skeleton underlings.
And he also had some new thoughts and understanding of their cooperative operation plan.
"Three black crystals are needed for the first career advancement. This one, plus the previous crystals, I still need about half more crystal..." Francis roughly calculated.
It was too slow for him to get black crystals by hunting his same kind.
It was far from killing the high-level skeleton, getting the black crystal in their heads.
"We have suffered a great loss for the first time to hunt high-level skeleton. We'd better strengthen our power first."
Francis put away the black crystal.
At present, he had reached level 10 and obtained the first skill.
What he needed to do next was to devour ghost fire, upgrade and collect the black crystals repeatedly.
However, the appearance of this high-level skeleton made Francis realize there are some new possibilities.
In the skeleton army, there might be a team made of high-level skeletons.
That would be the direct source for him to get the black crystals.
If he met this team, there would definitely be a big battle.
Therefore, he needed to accumulate his strength and make preparations for the future.
"The injury of Garbage also needs to find new bones to repair."
In this battle, Francis lost two underlings.
One of them was sprayed to death by the spiritual fire, nothing was left.
The other one was directly torn in half, whose end was the most miserable. He was still crawling on the ground to find suitable bones.
Francis was about to help him.
As a result, the skeleton army behind just stepped on it ruthlessly.
They trampled skeleton underlings on the ground into pieces.
Several skeleton soldiers felt their feet hurt. They rubbed the ground with all their strength, and the skull of the underling couldn't be put together. There was no way back.
Francis had no choice but to find powerful skeleton soldiers to make up for the loss of the two underlings.
Fast and Smart received his order.
They began to look for suitable candidates for underlings in the skeleton army spontaneously.
As their levels became higher and higher, their ability to understand Francis's orders was also augmented.
As soon as he thought of it, the underlings immediately understood.
It was much easier than before.
Garbage was finding suitable shoulder blades to replace in the skeleton army.
Things were really different, he was not as thin and weak as before.
Compared with his peers, he was particularly tall and strong.
The low-level skeleton couldn't resist his attack and fell directly to the ground. Garbage pulled off his shoulder blades by force and placed them on his own body.
Francis saw this.
He felt sorry.
The strong eat the weak and survive the fittest.
This law could be used in any world.
Smart's candidates for underlings also had some clues.
To help Francis use Slave's Rope successfully and to make up for the vacancy of underlings.
Soon, the eight teams gathered.
They followed Francis to protect him.
"Mouse explored the way ahead, found the high-level skeleton, and then gave warning. Fast was responsible for attracting low-level skeleton soldiers, Smart and Garbage to hunt..."
Francis's plan was simple.
He wanted that their cooperation could become more skillful.
Being familiar with the cooperation between team members.
It would improve the efficiency of hunting.
In this way, it could save Francis's energy too, so that he could find suitable skeleton soldiers at ease and devour their ghost fires.
In underlings, Garbage's was the highest, and he also had awakened his skill.
He is the real backbone.
The rest underlings took him as the center and formed a half circle, killing all the skeleton soldiers who were driven by Smart.
With the consent of Francis, Garbage also distributed some of the ghost fires to the underlings.
To enhance their strength.
Originally, these skeleton warriors couldn't be strengthened by devouring their same kind.
After being subdued by Francis, they had awakened that feature.
As long as there were ghost fires on the ground, they could use them to strengthen their body.
Due to the desire for strength, the new underlings couldn't help but pick up ghost fires. After being noticed by Garbage, he smashed them one by one.
They didn't listen to him until he taught them a lesson.
They gave ghost fires to Garbage and let him distribute them.
After getting ghost fires, Garbage handed most of the ghost fires to Francis flatteringly.
He assimilated part of them.
The rest were distributed to the underlings.
The sequence of distribution was also determined. Underlings with names such as Fast and Smart had priority.
The rest of the underlings were behind them.
Francis didn't need to remind him of the hierarchy, because it was obvious.
Garbage could do it very well.
"If he were a man, he would definitely be the first one in lackey."
Francis thought to himself, enjoying Garbage's tribute.
It was a skeleton head without skin and flesh, but he could see respect and flattery from the action of Garbage.
It had to be said that Garbage's getting smarter and smarter, and had completely mastered the secret of becoming stronger.
As time went by, the benefits of cooperation began to show.
Countless ghost fires rushed to Francis's body endlessly. He watched the progress bar of the upgrade, which increased rapidly at a visible speed.
It wouldn't be long before he could upgrade again.
To become a level-11 leader.
Among the low-level skeleton army, skeleton soldier whose level was 11 was definitely the best.
He couldn't find any opponents around.
With the help of his underlings, Francis was invincible.
"As my level goes up, the profit brought by low-level skeleton soldiers also gradually decreased..." Francis thought as he looked at the upgrade number brought by a ghost fire.
In the past, a level-5 low-level skeleton soldier could give him two points of experience.
However, as his level got higher and higher.
The experience brought by a level-5 skeleton soldier was also reduced to one point.
Ten could only bring ten experiences, which was too little.
Therefore, his goal gradually shifted to the level-8 skeletons. He let Fast give up hunting level-5 skeleton and look for more skeleton soldiers whose levels were eight or nine.
Currently, there were very few level-10 skeleton soldiers in the skeleton army.
Most of the skeleton soldiers nearby were still around level 5.
It was difficult to get a huge number of level-8 skeleton soldiers to upgrade.
Francis sent Mouse to scout ahead, trying to find a team of level-8 skeleton soldiers.
He had learned the rules of the skeleton army from his previous experience.
They were divided by their level.
It was not the army that was very confusing and with no destination.
Soon, Mouse brought back some message.
In front of them, there was a team made up of level-9 and level-8 skeleton soldiers. The number of them was about 100.
This cheered Francis up. He quickened his pace and took underlings to the middle of the team.
When Fast appeared in front of the level-8 skeleton soldier for the first time, he subconsciously raised his hand and was about to fan Fast away, but unexpectedly, Fast was very fast, he hid directly to the side.
Smart and the Garbage immediately followed and gave the level-8 skeleton soldier a blow.
It made him dizzy and circle around.
The underlings swarmed up and killed the level eight skeleton soldier. A cloud of ghost fire floated out from his body.
They killed several level-8 skeleton soldiers, Francis upgraded again!
Different from before, he could clearly feel the changes in all aspects caused by the upgrade.
Not only was his body strong again, but also a black crystal slowly emerged on his forehead and embedded between his eyebrows.
"Level 11!"
Francis said excitedly.
He could feel that the black crystals in his body were quickly becoming one smooth black crystal with infinite power.
Instead of scattering on the surface of his body as before.
Formed some black dots.
With these two black crystals and the black crystal robbed from the high-level skeleton, he had reached the advanced point, became a mid-level skeleton warrior!
Just as he was excitedly observing the change of his body, the second skill was unlocked.
"The marionette."
"You can freely choose a skeleton slave and establish a connection with him. You can fight from his perspective, and you can use skills, which will reduce the effect by half."
After reading the skill introduction, Francis tried to use Garbage to test his new skill.
Suddenly, a black thread rushed out of Francis's body and wrapped around the spine of Garbage directly.
Francis was dazzled. When he opened his eyes again, he had already come to Garbage's body.
"Isn't this the possession?"
He looked back at the direction he had stood in just now.
He found that the skeleton stood still.
Which looked a little silly without action.
Francis didn't have time to think it over, he used the Horizontal Slash.
