Alchemy & Martial Supreme

Not only that, they also searched the entire city, digging three feet into the ground to find all the treasures and black stones.    

Because after two hours, many of the Hero Spirits' bodies became unstable. Qin Ming stored them in his mind space.    

After about a day, Qin Ming released them again.    

The city was very big, so Qin Ming couldn't possibly take Qin Xixuan and search the entire city.    

He needed the help of the Hero Spirits.    

Qin Ming said, "The Hero Spirits can only stay outside for two hours. What a pity!"    

"If they can stay outside for an entire day, then I can let them mine the black stone veins for me!"    

The Hero Spirits were all good.    

But there were two things that were not good.    

First, they could not use pills to cultivate.    

Second, they could not stay outside for long.    

Since they could not use pills to cultivate, they could only absorb energy. This made the countless pills that he refined useless.    

If they could use pills to cultivate, with his Pill Tao strength, he would be able to help the Hero Spirits cultivate with all his might. He reckoned that many of the Hero Spirits would have broken through to the peerless realm by now!    

It was a pity.    

They could only absorb energy to cultivate, which greatly limited their growth.    

In addition, they could not absorb the energy in the outside world, but could only absorb the energy in the mind space.    

When they arrived outside, there was a lot of energy in the air, and they couldn't absorb it at all.    

This caused Qin Ming to only be able to place the black stone in his mind space for them to use.    

They couldn't stay outside for too long, and every time they fought with the enemy, they had to surround him.    

If they were too far away from him and couldn't be stored in his mind space in time, it might even cause his body to collapse.    

However, it didn't affect him too much. As long as he stored them in his mind space from time to time, their bodies wouldn't collapse.    

However, they couldn't stay too far away from him, which caused them to not be able to explain to the Heroic Spirits what to do.    

Qin Xixuan shook her head. "It's already not bad. The Heroic Spirits are very strong, and they have no weaknesses."    

Hearing this, Qin Ming also felt that Qin Xixuan was right.    

The Heroic Spirits had no weaknesses.    

Because they were energy bodies, even if someone chopped off their heads, they wouldn't die immediately. Instead, they would be injured and grow another head.    

This was very magical.    

Humans had weaknesses.    

If their heads were chopped off, they would definitely die!    

Even if their hearts were pierced through, they would die on the spot.    

Humans had many vital points, and the Vicious Beasts also had many vital points.    

As long as they were a flesh and blood body, they would have vital points.    

The Heroic Spirits didn't have any vital points because they weren't flesh and blood bodies.    

However, if they were hit too many times by the enemy, they would become extremely weak and eventually die.    

Moreover, there was a core in their chest.    

If the core was hit, they would die on the spot.    

However, because this core was their weakness, they were very protective of it.    

Of course, the energy body was not without its disadvantages.    

After they died, the heroic spirit energy that formed their bodies would be released and used by the enemies.    

The poison demon family had obtained all the heroic spirit energy from him from the corpses of the dead.    

Qin Ming did not have a good solution either.    

That was all he could do!    

Soon, the heroic spirits packed up all the corpses and went into every room.
