The underground river is deep underground, and the ground near it is slippery and not suitable for walking, and there are no roads at all in some places, so everyone can only wade through the water, because they have to go upstream, and Arlo's party is even more difficult to walk.

Pope took a sip and said, "This place is so difficult to walk, what did the elves walk back then." ”

He had just choked on a mouthful of river water, and he didn't care, he was more worried about Professor Green.

Professor Greene was tightly wrapped in an elven winged cloak, but the terrain was rugged, and Pop woke him up and down with him on his back.

Greene said: "You have forgotten the origin of the colorful winged clothing, the real elves have wings. ”

"If only we could fly." Helsinki said with emotion.

"Master said that monks can fly with foreign objects, but unfortunately we can't cultivate at home." Si Si also had a rare reflection, she usually wanted to fly, she could find the eaglet, but the space in this place was concave and convex, and it was obviously not suitable for the giant goshawk king to fly.

"But don't all elves have wings, Professor Green, what if half-blood elves like you want to go to the Sacred Lake?" Arlo asked Greene.

Ge Lin smiled bitterly: "Back then, a hybrid like me was not recognized by the elf clan, and he was not qualified to go to the holy lake. Even if it is a true elf, there are only a few who are qualified to go to the holy lake, and only the respected elf elders who die are eligible to be buried in the holy lake. Some elven elders knew that the time limit had come, and they would go to the holy lake in advance to meet death. And some elders will be buried in the holy lake after the accidental death of the remaining elves wrapped in colorful winged cloaks. ”

"The winged suit is wrapped around a corpse?" Si Si felt uncomfortable all over.

"Hehe, the color wing suit is a good baby, now you can't make it if you want to," Ge Lin smiled: "I originally thought that after I died, the color wing suit would be given to you, if the division dislikes ......"

"No dislike, no dislike, thank you, Professor Green." Si Si hurriedly said, but in private, he also sprinkled smoked powder on himself and Arlo.

"In that case, I'll leave you and Pophull respectively when I die, Professor Kunding......," Greene looked apologetically at Kunding.

"It doesn't matter, just leave it to the children." Kun Ding said freely.

"And the heart of the tree, we'll give it to you." Pope said hurriedly.

"But we haven't found anything green glowing after walking for so long." Helsinki said.

Along the way, Khundin explores the way, and Pope and Arlo carry people on their backs, and it is Helsinki who is responsible for exploring the hearts of the surrounding trees.

"It's so easy to find the heart of the tree. I spent three years in this underground river, and I searched for three years before I found two. Greene sighed, "After that, I brought my students to look for them many times, but not only did I find nothing, but I also killed them. ”

No wonder Greene was not in a hurry when he heard that the orcs knew that there was a tree heart underneath the elven ruins, and this tree heart was too difficult to find. Everyone wanted to complain, but they couldn't say anything when they saw Ge Lin's sad appearance.

"Fortunately, there are no orcs here, safe, wait for us to settle Professor Green, and stay here for a while to look carefully." Kunding said.

"That is, you said that if we stay here until the end of the thousand-year catastrophe, can we avoid being involved in the catastrophe?" Pope continued.

"Don't forget that this is the site of the elves, and the elves perished in the Holocaust." Si Si reminded.

Somehow, Si Si always felt that something was wrong. Shaking her head to suppress her uneasiness, she only thought that she was under the influence of the big mink.

In fact, Si Si's feeling was not wrong, there was a pair of eyes peeping at them in the dark.
