678 The second disease

After spending three achievement points, Sheyan successfully upgraded his ‘Flu’ ability to lvl 4. Even so, the probability of inflicting sneeze, shivers,and headaches only grew to 11%, where each level merely upgraded 2%.

Still, a Rank S ability with 9 tiers undoubtedly couldn’t be discounted. When the ability ascended to level 4, a bonus property option was awarded.

[ A: Intervals of triggering ‘Flu’ negative effects lowered from 10 to 7 seconds ]

[ B: Increase ‘Flu’ contamination radius by 20 metres ]

[ C: Decreases ‘Flu’ outbreak timing by 3 minutes ]

[ D: Increase probability of sneezing, shivers and headaches by 3% ]

Sheyan then opted for option ‘C’, thereby lowering the outbreak duration to 7 minutes. Sheyan was extremely satisfied with this, and when the ‘Flu’ ability was upgraded to level 4, the branching skill changed to the term ‘Influenza’.

Following that, the nightmare imprint transmitted another notification.
