What bothered Li Yao most was not just the formidability of the soldier of the Nether World Watch but also the strengthening necklace he wore.

Li Yao could see that, in the research room that was one glass wall away from the test field, there were dozens of necklaces of the same model on the table, with almost a hundred different-colored strengthening drugs next to them.

The strengthening drugs and the necklaces could be paired freely. Other than the crimson drugs, there were also light gray, violet, and azure ones, each of which was emitting mysterious brilliance and dense spiritual energy.

It meant that such strengthening necklaces could very likely trigger frost, poison, corrosion, and a lot of other effects besides the incendiary effect.

If all the soldiers of the Nether World Watch are wearing strengthening necklaces, with the 'biochemical firearms', they will definitely be strong enough to crush any main-force legion of the federal army!
