Unlike the Special Supreme-ranked talent, the normal talents like [Battle Axe Mastery] didn't have any additional requirements other than spending the [Supreme Promote Points].
The only thing that Leo lacked right now was the [Supreme Points] as he had already accumulated more than two million [Supreme Promote Points] by killing the supreme-ranked dragons.
'Ding,
The host spent 10000 [Supreme Promote Points] and upgraded his talent [Battle Axe Mastery] to level 4.
'Ding,
The host spent 100000 [Supreme Promote Points]...
'Ding,
The host spent 200000 [Supreme Promote Points]...
'Ding,
The host spent One million [Supreme Promote Points] and upgraded his talent [Battle Axe Mastery] to level 7.
Leo made his decision to upgrade the [Battle Axe Mastery] from the beginning and he was waiting for the right moment while accumulating the [Supreme Promote Points].
Because he was confident that with the help of all the perks he would get by upgrading it to level 7 supreme rank, he could kill a level 9 supreme-ranked dragon whose battle prowess was suppressed by 29 percent.
[Weapon Skill - Titan Strike]
'Kacha'
The Marsh Dragon King didn't think much and let Leo attack him as he wanted Leo to learn the gap between them.
'Once he sees the gaps between us, he will come quietly with us.'
Since their Dragon Emperor wanted the human alive, they decided to let him see that no matter what Leo does, he could not kill even the weakest dragon king, not to mention the strongest dragon king.
'Kacha'
However, in the next second, their jaws drop when they see the Marsh Dragon King's huge head rolled on the ground.
'Who is this possible?'
'Is he really a low-level supreme-ranked human?'
'No, suddenly, his strength rose to level 7 supreme rank; however, it was only because of a normal talent. There is no way he could kill a level 9 supreme-ranked dragon king in a single strike.'
[What the hell! What is happening? How did he do that?]
Not only the four dragon kings, hundreds of dragon generals, and thousands of dragon captains but even the Dragon God was also shocked when he saw Leo behead the Marsh Dragon King in a single strike.
'Ding,
The host has killed a level 9 supreme-ranked Marsh Dragon King and gained 1000 (x 10) [Supreme Promote Points].
'Ding,
The host has made some progress in the normal mission. Kill the remaining four dragon kings to complete the mission.
'Ding,
The Ancient Primordial Dragon God's hatching time has been reduced by 100 days after killing the Marsh Dragon King.
.
.
.
On the other hand, Leo's head was filled with system notifications as he looked at the corpse on the ground.
'Hatching time is reduced by 100 days. What if I kill the remaining four dragon kings? Will it be reduced by another 400 days?'
The first two system notifications didn't surprise him much; however, when he saw the third system notification, Leo was surprised and he was excited to kill the remaining four dragon kings.
'Since I have to kill them to complete the mission anyway, this is such an unexpected reward.'
Earlier when the system had collected the full information on his world, Leo had received three missions from the system.
They are:
1) Mission Name: Eliminate the Dragon Rulers.
Mission Type: Normal.
Objective: Kill the five dragon rulers under the dragon emperor.
Reward: Five Special Talents.
2) Mission Name: Dragon Slayer - Part 2
Mission Type: Bonus
Objective: Kill as many dragons as possible. The more, the better.
Reward: Every time the host kills a certain number of dragons, the percent of the effect of the [Dragon Slayer] will be increased.
3) Mission Name: Void Dragon's Family Reunion.
Mission Type: Special
Objective: As someone who knew and experienced staying away from the family, you feel pity for the Void Dragon King. Try your best in reuniting the Void Dragon King with his family.
Reward: Void Dragon Family's absolute loyalty.
Penalty: None.
Earlier, Leo focused on the bonus missions and increased the effect of the [Dragon Slayer] from 25 percent to 29 percent.
Since the five dragon kings have arrived, he started focusing on the normal mission.
As for the special mission, Leo didn't have much hope for it and since there was no penalty for it, he didn't bother too much about it.
[Absolute Devour]
Before rushing towards the next dragon king, Leo devoured the corpse of the Marsh Dragon King.

Since the Marsh Dragon King was a level 9 supreme-ranked dragon king, Leo's chances of resurrecting it were very less and as for giving sentience to it was almost impossible unless he had that [Incredible Luck] from before.
Therefore, the best choice for Leo was to devour the corpse.
'Ding,
The host devoured the level 9 supreme-ranked dragon king.
'Ding,
The special effect of the [Absolute Devour] triggered and the host received three Talent Awakening Crystals sent to his storage ring.
'What? Three Talent Awakening Crystals?'
Leo was shocked when he heard the system notifications; however, it turned into his motivation to kill the dragon kings.
"Next, who wants to show me the gap between our strengths?"
Leo's eyes were focused on the Stone Dragon King as he asked them with a mocking smile on his face.
"Everyone, there is no need to hold yourself back anymore. Kill that b*stard."
Earlier, they were so confident and looked down on Leo that he could not even leave a scratch on the level 9 dragon king; however, he had beheaded it right in front of their eyes which was a loud slap to them.
Also, the Twilight Dragon King was the type to easily offend. So, with Leo's slap in their faces by killing the Marsh Dragon King right in front of their eyes, he could not bother to follow the Dragon Emperor's words anymore.
Therefore he ordered everyone, whether it was a dragon general or a dragon captain or even a dragon king, everyone except for him, to rush toward Leo to kill him.
"But, Sir Twilight…"
"There are no buts, I will take full responsibility for killing this human brat. So, you just need to kill him."
Before the other dragon kings could finish their words, the Twilight Dragon King interrupted them and said he would take full responsibility.
"Everyone, attack."
After hearing the Twilight Dragon King's orders, the three dragon kings looked at each other for a moment and nodded their heads before ordering their minions to attack Leo.
Until now, Leo had only killed the minions of the Stone Dragon King and the Marsh Dragon King along with the thousands of the Tempest Dragon King's minions.
So, the remaining dragon king's minions were still in their full form as they rushed toward Leo.
"My next target is Little Tempest."
However, Leo was not worried much as he looked at the attacks coming toward him as he selected his next target.
"Tempest, activate your defensive skills."
After learning their lesson the hard way, the dragon kings were no longer careless and they hurriedly ordered the Tempest Dragon King to enhance his defence.
[Space Manipulation - Teleportation]
'Swoosh'
Leo dodged all the attacks from the dragons using his teleportation and appeared above the Astral Dragon King.
"Sorry, but I changed my target to Little Astral."
With an evil smile, Leo used the same tactics that he used to kill the Marsh Dragon King.
