As a result, this Thunder Mountain Range did not disappoint Long Ying.

Just a few steps away, you can meet a few thunder lizards. It's just that none of the ones encountered after that were as big as the first one killed, and not as high as the first one. But fortunately, there are many of them, and a large piece of it is fried, and the crystal nucleus is collected in a basket. Fortunately, there is a space ring on Nan Guowen's body, otherwise, hundreds of crystal nuclei may be lost in place.

By the time they entered the depths of the Thunder Mountain Range, they had not only harvested more than three hundred thunder-attribute crystal nuclei, but also raised their levels.

Ahri is already a sixth-level green realm spirit beast, and if he encounters the fifth-level black realm thunder lizard from before, he can easily kill it.

And the speed of the dragon tassel's promotion is even more jaw-dropping, almost every ten thunder lizards killed can advance to one level, and four levels is the first level. It took half an hour to kill more than 300 thunder lizards. The strength has reached the fifth level of the Black Realm Warrior.

During this period, he also deliberately released water for Nan Guowen to practice. Finally, Nan Guo Wen's martial arts cultivation level was also greatly raised, reaching the level of a fourth-level Black Realm warrior.

They pursued all the way until sunset, and they came to the last section of the Thunder Mountain Range.

It's a place where few people set foot and the roads are out of the question. They had to carve out their own paths, overcoming obstacles, through a dark and dense jungle, over layers of obstacles, and finally stopped in front of a cave.

The surrounding stone walls are covered with moss and vines. Almost obscured the entrance to the cave. There is only enough place for people to walk in and out. The light doesn't shine in, and from the outside, it looks like a bottomless abyss inside. It's pitch black. From time to time, there is an eerie cold wind howling, as if there is an unforeseen monster hidden in it, which is terrifying and abnormal.

"Miss Long, we have gained a lot today, let's go home!" Nanguo Wenjian yì road.

Hearing this, Ahri also nodded immediately, and said with an approving expression: "Yes, yes!" ”

"Aren't you entering Baoshan and returning empty-handed?" Long Ying spread out her hands, her hands were indeed empty, and all the crystal nuclei were contained in Nan Guowen's space ring.

Ahri immediately said with an aggrieved face: "Master...... We've all hit so many crystal nuclei, and Ahri can feel that there's definitely something terrible in that cave, let's not go in, okay? If it is the king of the thunder lizard, it must be many levels higher than the previous fifth-level black realm spirit beast, and Ahri will not be its opponent, it is so terrifying to think about......"

Seeing this, Long Ying shook his head and said, "Nan Guowen, you are here watching Ahri, I will come when I go." ”

Nan Guowen's face was full of worry, and he said urgently: "You have to be more careful!" If the situation is not right, come out quickly, and don't carry it in it! ”

After thousands of instructions, Long Ying just looked back and smiled, and the smile between them was like a flower. There is a beauty in the heroic spirit that makes people can't look at it directly.

Long Ying still didn't realize it, but walked into the pitch-black cave alone where she couldn't see her fingers. The more you go inside, the more you can feel the gust of wind. It was as if some low roar echoed around the stone wall.

I don't know where I went, Long Ying only felt that the place seemed to be much wider. Then he took out the fire fold from his bosom and opened it.
