There was always a strong yin aura in the tunnel, so Chi Yu had to constantly urge the spiritual power to maintain the enchantment.

Suddenly, Chi Yu took out a crystal clear stone, saying that it was a stone because its texture was completely different from jade, and it was not completely detached from the essence of the stone, and it looked like a slightly transparent stone.

Chi Yu urged the spiritual power to activate the stone, and a powerful spiritual power gushed out of the stone and was converted into Chi Yu's hand, which was used by him.

"What's that?" Gu Linger asked.

"Spirit stone, there is spiritual power in it that can be used by me, but after all, it is much worse than my original spiritual power, and I am not so freewheeling." Chi Yu said.

"Uh......" Gu Linger responded.

Chi Yu seemed to remember something, and took out some spirit stones, "The purer the texture and the bigger the size, the better, I don't need these low-level spirit stones, give you self-defense." ”

Gu Linger had already taken a lot of good things from Chi Yu, and she didn't care about taking more at the moment, so she took them politely, knowing that these things were very likely to save her life at a critical juncture, so she naturally wouldn't be polite.

At this time, I don't know when a lot of small black dots appeared densely on the ground in front of me.

Chi Yu saw it and said, "It's not good! ”

The small black dots surged over densely, and Gu Ling'er felt the yin aura burrowing into the small black dots, and the small black dots became larger, and they also grew wings and flew into the air.

It wasn't until they moved quickly and grew larger that Gu Linger saw that the black spots were insects, and the wings on their backs were still shining.

Seeing Chi Yu's gloomy expression, Gu Ling'er immediately became nervous, "What are those bugs?" ”

"Gold Eater! I didn't expect there to be a gold eater here! These insects are not bound by space, and they can devour people's cultivation and spiritual power! Ordinary things can't kill them! As he spoke, Chi Yu had already taken out a long sword inlaid with gemstones.

The long sword hung in mid-air under the urging of his spiritual power, and Chi Yu pulled her to jump onto the long sword, "The speed of the sword will be faster." ”

Before Gu Ling'er could figure out what was going on, Chi Yu had already pulled the sword and flew quickly, and she didn't know what to do at this time, so she had to hold Chi Yu's hand tightly.

Slowly, in fact, it is only a few seconds in the past.

At the same time that Chi Yu took Gu Ling'er to meet him, he had already released a beautiful bird with red feathers, which was much better looking than ordinary spirit birds before, with much longer feathers and a larger size.

With a wave of Chi Yu's big hand, the red spirit bird rushed to the front and spewed out a large mouthful of flames.

Those gold-devouring insects were very powerful, and they were unscathed, but the flames of the red spirit bird also had some effect, and those gold-eating insects seemed to be burned a little frightened, and were hit to the side by the flames, revealing a large piece of space in the middle.

Chi Yu immediately rushed over with his sword, "The Red Flame Bird is spraying three true fires, but it is still a young bird, so its power is limited, unless it is an adult bird, it can hit the Gold Devouring Worm hard, it's a pity that I have some spirit pets that I can't use, otherwise I won't be so passive!" Chi Yu said.

"Do you have to have three true fires to destroy them?" Gu Linger asked.

"There are several ways, but basically impossible, one is to tame them but defeat their owners and erase their marks, and the other is to use strong spiritual power to destroy them, but it is also unlikely, because there are too many of them, it is impossible to destroy one, and so many more...... Don't even think about it! Chi Yu said.
