{Good morning ,Host.You got 100k mora from the passive skill.}

When (Y/n) woke up,the first thing she heard is the greeting from the System.

"Good morning to you too."

{Host!I have good news.Your mission reward has been arrived!Do you want to check?}
The System said with excitement.

"Oh,I almost forgot about it.Show me what I got."
(Y/n) said.

{Host,your reward is 'Upgrade Function'.You can upgrade your skill from now on!}

"Really?!"
(Y/n) said.She quickly turn on her upgradeable skill list and found there is additional bottom under each skill.

[Teleport(upgradeable)-Teleport to anywhere.Range is 100 m.Cooldown is one minute.][Upgrade?]

[The protection of the wind(upgradeable):Create a wind barrier around the user for one  minute.During the time,the user atttack speed and movement speed is increased by 20%.The skill cooldown is 3 minutes.]
[Upgrade?]

[Sacrifice Healing(Upgradeable):Heal the injured person to perfect condition.However,after using the skill,the user suffer backlash and enter the weaken state depending on injury.The weaken state duration will not exceed one week.

Warning:This skill cannot resurrect the death person.You can't heal yourself with this skill.][Upgrade?]

[Daily Mora(passive) (upgradable):Receive 100000 mora daily.][Upgrade?]

Although she only have few upgradeable skills,she believe that there will be more upgradeable skills in the future.Besides,she is very happy that the upgrade Function is unlocked.

What is concept of upgrade?

It will make her skills more powerful or useful!Even in game,character skills must upgrade to get stronger.So,this function is undoubtedly very useful for her.

But when she thinks about it carefully,she completed two mission.The Unique mission and emergency mission.How come there is only one reward?

"System,I completed two missions.Why there is only one reward?"

{Host,I let you use my power in emergency mission.That's why you won't get the reward from it.}

"I see.But why did you hide the fact that you can use your power in outside world?"
(Y/n) said.

{Every Systems can use their power in outside world but the Main System forbid us to use our power.I break her rule and she is very angry right now.Now,she temporarily banned most of my power.}

"Thank you,System.I will work hard to become stronger."
(Y/n) recalled the scene about Rosalyne jumping from the building.

Although with her current abilities,she can at least protect herself but she still can't protect the other people without the System's help.So,she think that she must work harder and do more missions.

{I believe that you will become powerful,my Host.Now,hurry up and upgrade your skill.(⁠≧⁠▽⁠≦⁠)}
The System feel very moved when he heard (Y/n)'s word.Is this the feeling that my seniors are talking about?

(Y/n) 'tap' the upgrade bottom of teleport skill.The two options appeared before her.

[Upgrade to max level using Skill Fruit.] Or [Upgrade to level 2 using Mora 100000.]
