25. Modify Rune

In front of the stone door of the Stone Tomb.

Corporal Mars and his group were leaning against the door, panting heavily.

A fierce battle had just taken place here.

Over thirty frenzied Stone Tomb Bound Spirits surrounded Mars and his men.

Penetrating, biting, and icy cold touches that could steal one's soul.

The forked lightning released by the Lightning Spore couldn't stop these crazed spirits.

It was a suicidal attack.

The Bound Spirits that surrounded Corporal Mars and the others eventually vanished in the lightning, but the human side also paid a heavy price.

Three sergeants died in battle, and the survivors were left utterly exhausted.

"Hang in there, mates,"

Corporal Mars reached into his pocket and pulled out an all-metal injector.

Without hesitation, he stuck the needle into his neck, pushed the plunger forcefully, and injected the unknown colored fluid into his body.

His face twisted in pain, but the fatigue quickly faded away.
