After Kyoko was promoted to level 4, Su Hao supported her with 2000 universal points and helped her light up Insight X.

With this divine skill, the group entered the mine.

However, before entering the mine, Su Hao took out a tracer bullet, loaded it into the revolver, and then fired a shot into the depths of the mine.

The warhead flew out, dragging a sparkling trail of fireworks through the darkness, then submerged in the depths and extinguished.

Seeing this, Su Hao nodded and said, "Yes, there is no flammable gas in the mine, you can enter." ”

Seeing this, the squad leader couldn't help but extend a thumbs up to him and praised: "Yes, you are very careful." ”

Su Hao didn't answer, but looked into the depths of the mine.

The mine is deep and dark, you can't see your fingers, and the light conditions are so poor that it is not at all an environment that can be seen clearly by human eyes.

However, the evil creatures inside live in such an environment, I am afraid that they have been living for a long time, and it is very likely to evolve a special vision to adapt to such a dark environment.

However, Su Hao had already thought of this, and he prepared the lighting tool: mutton fat torches.

When the torch is lit, the firelight instantly dispels the darkness around it. Su Hao handed over the torches to the Iron Stone Demon, Paladin, Nurse and Radar respectively, after all, they are all similar auxiliary positioning, and they don't need to fight much, so they only need lighting.

In addition, as a pure creature made of metal, the Iron Stone Demon has no psychological fluctuations such as fear, so it is perfect for it to carry a torch to explore the way ahead.

Illuminated by the firelight, the group entered the mine and continued along the tunnel.

Luckily, they didn't encounter any enemies along the way, but within a minute, they came to a three-way intersection, each with a tunnel extending into a bottomless darkness.

Facing this three-way intersection, the squad leader looked at Su Hao and asked, "What should I do, where are we going?" ”

Su Hao said lightly: "Send the mechanical unit to check it first, and then decide the route." ”

The apprentice let out an "um" and summoned a hummingbird drone to investigate.

Although the light conditions in the mine are poor, the drone's camera can barely see.

The Hummingbird drone went back and forth three times, and the apprentice also reported what the drone had seen and heard. In the first 2 investigations, the drone found an excavated stone chamber deep at the end of the 1st and 2nd forks, which consisted of a lot of exposed ore, as well as some Rogge and miner's corpses, these corpses died in a miserable state, and their body posture showed a desperate struggle, apparently suffering inhuman torture while alive, and dying painfully in this torture.

The apprentice also discovered that the exposed ore was of high quality and varied, including iron, silver, and phosphate minerals, and it was not known how they were enriched in a single mine, which obviously turned the apprentice's perception upside down.

But it's a good thing, as with enough materials, the apprentice can start building a wide variety of grenades, primary deployers, primary battery-powered engines, and the M134 airborne revolver rapid-fire machine gun.

However, so many mineral deposits, like a mountain of gold, are obviously not so easy to start excavating, and the Hummingbird drone also found some wandering black wanderers, skeleton warriors and starving dead near those ores, as if they were obsessed, even after death, they also guarded those ores and did not let people easily touch them.

After listening to the apprentice's report, Su Hao decided to go to the first fork in the road first.

The group moved along the tunnel, and after 10 minutes, the radar seemed to sense something, and immediately reminded: "Be careful, 100 meters further is the exit of the tunnel, which is linked to a stone chamber, and there are many enemies in the stone chamber!" ”

Su Hao said: "Those enemies, there is no doubt that they are black wanderers, skeleton warriors, and starving dead, let's speed up and end this battle as soon as possible, and then let the apprentice start digging some ore." ”

The apprentice said, "With ore, I can make more mechanical units and all kinds of ammunition. ”

The squad leader nodded, he also needed grenades and ammunition, so he said, "Okay, let's speed up." ”

Soon, the 100-meter-long tunnel was completed and the tunnel exit was in sight. Under the order of the apprentice, the Iron Stone Demon stepped out with a mutton fat torch in his hand, but the firelight illuminated the terrifying and dirty faces! There are skeleton warriors with hollow eyes and white bones and mining pickaxes in their hands, starving dead with festering green sheen, and black wanderers with longbows and arrows and bloodthirsty faces!

At the moment when the Steel Stone Demon appeared, 6 or 7 arrows flew in, hitting the Steel Stone Demon in the chest!

The arrow collided with the steel stone demon's chest, making a steel scraping sound, but it did not cause any effective damage, but it was the steel stone demon, following the trajectory of the arrow, he saw black wanderers! These guys were Rogge archers in their lifetimes, but they still have mastered the art of archery after their deaths!

The Iron Stone Demon took the torch and walked towards the other party step by step.

Just as it was halfway through, skeleton warriors approached with squeaky steps! They swung their pickaxes and slashed at the Iron Golem's body.

The tip of the pickaxe scraped the skin of the Iron Stone Demon and slashed it down, causing a series of sparks in an instant, but it only left a scar on it, but it did not cause effective damage. This is the strength of the Iron Golem, the Iron Body can easily avoid most damage when faced with pure physical attacks.

The Iron Stone Demon danced its claws and swung it down at the two skeleton warriors in front of him! The sharp tip of the steel claw slashed through the white skeleton, carving a deep scar, apparently causing a lot of damage, and at the same time triggering its own material properties, condensing a terrible layer of hoarfrost on the skeleton, and plunging it into a frostbite state!

The skeletal warrior in the frostbite state has a great impact on his speed, and within a few seconds the threat is greatly rewarded, and the starving dead are scrambling one after another, directly pounced on the steel stone demon, constantly gnawing at the opponent's steel body, even if the front teeth collapse!

The appearance of the Iron Stone Demon attracted almost half of the enemies here to its side, and at this time, they were like a flock of lambs gathered together to be slaughtered.

Su Hao's right arm was deformed, and the demon liquid gold instantly solidified, turning into a weapon similar to the blade of the demon hunter Aeginos: the Scarlet Crescent!
