Then, he precisely embedded the tail of the flint spearhead into the groove, ensuring the angle and position were perfect. He took out a small black block, resembling tree resin.
"This is natural glue made from a mixture of spruce resin and charcoal powder." He heated the glue block by the fire until it softened, then evenly smeared it over the joint between the spearhead and the wooden shaft, filling all the gaps.
Finally, he took out the steel tripwire and, with full strength, meticulously bound the spearhead and the wooden shaft together in a crisscross fashion.
Once the steel tripwire and resin glue had fully solidified, a flint spear approximately two meters long, its center of gravity perfectly exuding a primitive aura, was created by him!
An extremely clear and aggressive plan had already formed in his mind.
