After Lina and Neron realized all the envoys had been killed before they could return to the Geyser Kingdom, their first wasn't to investigate the culprit.
"Whoever killed the envoys has a clear motive. They want the relationship between the Crawford Kingdom and the Geyser Kingdom to deteriorate. We are in danger by staying here, Junior Sister. Let us make haste back to the kingdom!" Neron stressed.
"Yes, Senior Brother!" Lina nodded solemnly.
Nevertheless, they did not ignore the corpses of the envoys. They quickly collected all of the corpses into their interspatial storage before they went on their way.
The envoys were all Preliminary Accession-stage Transcendents at the very least, while the strongest envoy among the bodies was even at the Seeking Insight-stage Transcendent.
They weren't just nobodies in the Geyser Kingdom.
