Charlotte and Daisy focused on their training over the past month, occasionally consuming Red Fruit No. 4 to replenish their Chi.
Recently, both advanced to the third tier.
Before their advancement, Gabriel had upgraded to the third tier by consuming Blood Spirit Grass, while Bella and Hannah achieved the same tier through Crystal Grass.
Others also made progress. Grace had eaten Blood Spirit Grass as well, but as she wasn't a physique-type ability user, the effect was less significant.
She came very close to advancing to the third tier and will likely make the leap once the Blood Spirit Grass matures again.
Katherine, although she didn't specifically consume spirit plants, regularly tasted fruits from the Red Fruit cultivation and accumulated substantial Chi, only needing a final push.
With Fiona and Lily already at the third tier, the Azure Isle forces had entered the third-tier era.
Despite this, Charlotte didn't express any desire to go to "Serenity Peak" because she understood Elijah. Without someone of the same tier staying behind, Elijah wouldn't feel secure leaving for a long distance.
Charlotte waited for an opportunity, and with the maturity of the Dancing Grass and Fiona's successful advancement to the fourth tier, the moment finally arrived!
She proposed to Elijah that they should go see "Serenity Peak."
Elijah did not refuse. He and Fiona had long been curious about the mysterious "Serenity Peak." He considered the current state of Azure Isle.
After Neoville City was connected, Fiona organized teams to clear zombies from the three districts in the city center and to infiltrate the surrounding areas.
Additionally, they dispatched several teams to clean up some factories, preparing for future production.
Everything was progressing smoothly.
One district in the city center had been cleared, and infiltration around Neoville City was also successful, particularly in the old town's northern area, which housed one of the country's top inland ports.
This port was now occupied by Azure Isle, providing a large amount of resources.
Several factories producing daily necessities had even attempted to resume operations.
Currently, Azure Isle had full control over the survivors in the Neoville City area and had established good cooperation with the military.
The environment was very stable, with a promising future.
After reaching the third tier, Charlotte's inner vision evolved into spiritual vision, which is no longer limited to observing the surroundings of the body but can extend to distant places.
Through this spiritual vision, Charlotte observed that if the Snow Lotus Fruit does not receive energy from a corpse core, and only absorbs Chi from the air, its growth rate will be extremely slow.
It can grow, but to accumulate enough Chi to bloom and bear fruit will definitely take several years, or even decades.
Therefore, Charlotte concluded that the Snow Lotus Fruit is currently the highest-tier spirit plant that can be nurtured in the existing environment.
Higher-tier spirit plants cannot grow due to the current Chi concentration.
So, Elijah is facing a rather awkward situation: either he diligently meditates and spends several years or even decades to reach the fifth tier, or he goes to the so-called "Serenity Peak" to try his luck.
Since he's idle anyway, he might as well go out and explore!
Elijah is determined. Since he has decided to go, he needs to make thorough preparations.
First, Abigail and Kylie have been consuming third-tier corpse cores for a while.
However, advancing from the third tier to the fourth tier by eating corpse cores takes an exceptionally long time.
Abigail told Elijah that she has a feeling that the advancement is imminent in the next few days.
Abigail and Kylie advancing to the fourth tier will give Elijah more confidence in dealing with the dangers at sea or any potential dangers at "Serenity Peak."
Secondly, regarding transportation, they can only travel by ship at the moment.
Fortunately, Country A is not far from Neoville City, with a straight-line distance of about 700 kilometers.
Finding a large yacht and filling it with fuel, along with carrying some extra fuel, should be sufficient.
Once they arrive in Country A, they will gather more fuel for the subsequent voyage and return trip.
Finally, for the team, besides Elijah, Charlotte, Abigail, Kylie, and the three powerful zombies, there will be several other third-tier zombies.
Additionally, Daisy has been insisting on going along, and lastly, they need a driver, which can only be Sophia.
Although Daisy claims she can drive a yacht, and after more than a month of Sophia's training, she has graduated, Elijah does not agree at all!
Everything is ready! Soon, Abigail and Kylie have finally advanced to the fourth tier!
