After gathering as many samples as they could, Linus, Nina, and Samir went back to the mountain settlement to meet Raymond. He asked the man to prepare the needed porcelain laboratory equipment for the refinement of penicillin. Raymond complied and requested available porcelain workmen to deliver the goods to the Chief's Hall in Stoneaxe town.

In addition, Linus instructed Raymond and his crew to start the mass manufacture of steel rebars of different gauges, explaining their necessity in creating bigger and stronger structures. Including Samir, Linus demonstrated to them how reinforced concrete is formed using sand, Portland cement, gravel, and steel bars. With the help of the skill <Art of Teaching, Lv.3>, the crew immediately grasped the theory behind the practice.
