After entering the waterway under the holy well, Honggu asked Mr. You Guang, "Sir, is there any new record of the inscription on the eighth layer?"

Mr. You Guang said: "Yes, there is, but there is still no mention of how this mushroom spirit can coexist with Xuanzao. ”

Honggu said: "What are the new records in other aspects?"

Mr. You Guang said: "Yes, it is about the change of water quality, the ninth layer of the cave is connected to the sea, so the water in it is mainly seawater, but after moving upward, the water in the cave above is not seawater, so they have to try to change the water quality, or change the species of algae, in order to grow a kelp jungle in it." On the eighth floor, they were changing the quality of the water, and when I read the inscriptions, I had already seen that the composition of the water was indeed the same as that of seawater. However, the water quality above the seventh layer is not seawater, indicating that they have changed the species of giant algae. ”

Honggu said: "In that case, why is there no mention of this matter above the seventh layer?"

Mr. You Guang said: "In fact, there is an inscription on this matter on the stone pillar outside the seventh-floor palace, and they have changed the species of giant algae, and even changed the variety of the algae that coexists with themselves. ”

Mr. Cicada wondered, "Oh? How did they do it?"

Mr. You Guang said: "The inscription is vague, but it only says that it was taught to them by Teng Snake. ”

Honggu sighed: "Alas, it is indeed unrealistic to expect that the inscription is very detailed. ”

Gu Xiang Demon Sword said: "Actually, compared to these, haven't you noticed a more strange thing? The mushroom spirit at the bottom of the mine said that it had returned to the underground water world, but until the eighth layer, the city was still empty, and there was no trace of the mushroom spirit living at all. ”

Feng Luqi said: "This is indeed a problem, and I think the possibility that the ninth layer currently has a mushroom spirit life is also very small, after all, their population has grown too much in 30,000 years, and a city simply can't accommodate so many mushroom spirits." ”

Mr. You Guang said: "Well, what Lu Qi said is very reasonable, but whether this is the case or not, you still have to really reach the ninth layer to know." ”

Everyone dived quickly in the waterway, and they had already dived for miles before they spoke, and the exit of the waterway was already in sight.

After leaving the waterway, the ninth-level city was hidden in the kelp jungle and appeared to everyone.

The giant algae in this cave are surprisingly tall, and some of the top of the giant algae have even touched the top of the cave, and even reach as high as a mile.

There was even a holy well in this cave, and the statue of Liren still dived straight to the holy well, Mr. You Guang said: "How can this be? This is already the ninth layer!"

Mr. Cicada said: "Maybe Mr. Elephant put the artifact component in a cave connected to the holy well, and it is only a matter of time before the artifact is found, so you should take a look at the inscription next to the holy well first." ”

So Mr. You Guang looked at the inscriptions related to several buildings next to the holy well, and finally said to the others: "Sure enough, the temple at the bottom records the most original myth of the origin of this mushroom spirit, although the content is not much, but the details are more complete, and there is even a detailed record of the Teng Snake. ”

"Oh, sir, please!" the others were concerned.

Mr. You Guang said: "In fact, the ancestors of these mushroom spirits are indeed the remnants of the mushroom spirit empire, 30,000 years ago, the first generation of mushroom spirits mysteriously disappeared, and the remaining mushroom spirits on the Six Poison Island continued to fight against the six holy clans, some were slaughtered, some were enslaved, and some escaped into the depths of the underground to escape the pursuit of the six holy clans, which is the ancestor of this group of mushroom spirits." ”

Mr. Cicada said: "Old ghost, what are you, these Honggu princesses have already guessed after seeing the reliefs in the temple on the first floor of the underground world, you still have to talk about something." ”

Honggu said: "It's okay, I was just guessing at the time, and there was no evidence, but now it's finally confirmed." Please go on, sir. ”

Mr. You Guang said: "These mushroom spirits went through a lot of hardships in the depths of the underground and died most of them before they finally reached the deepest part of the Six Poison Islands, the cave that connected to the sea, and in the end, only a few escaped into the sea, wanting to find a small island in the sea to settle down.

However, they searched for a long time, but they could not find a place to stay, but they lost a lot of people at sea. The survivors eventually encountered the Naga tribe of the sea, whose leader was the Teng Snake, who used a spell to give the ancestors of this mushroom spirit the ability to live in symbiosis with the algae, giving them the ability to live in the water for a long time.

However, the Six Holy Clans sent troops to the sea to search for the fleeing mushroom spirit, and it was not enough to escape the pursuit just by living at the bottom of the sea, so Teng Snake let the mushroom spirit settle in the underwater cave where the Naga tribe lived. The Six Holy Clans did not dare to raid the territory of the Naga Clan, and these caves were originally secret enough, so this mushroom spirit was finally safe.

They lived with the Naga for a long time, until the population recovered to a certain extent, and then migrated to the cave under the Six Poisons Island, which connects to the sea, and established their home there, which is the city. Because of their great favor from the Naga, the leader of the Naga, Teng Snake, gradually evolved into a god they worshipped.

Although they later broke away from the protection of the Naga tribe, out of gratitude, they have been refining Qingming crystals for the Naga tribe and dedicating these crystals to the Naga in the form of sacrifices. ”

Feng Luqi said: "Why does Naga value the Qingming Crystal so much, and what is the use of this for them?"

Mr. You Guang said: "It is said that the Qingming Crystal is very important to Naga's cultivation. ”

"It seems that this city is still uninhabited, why are these mushroom spirits returning to the depths of the earth, and where are they settled now?"

Mr. You Guang said: "The strange thing is that when this mushroom spirit returned to the depths of the underground, it did not leave any inscriptions in the nine cities, it seems that they don't want to be known where they are, but I think they should have gone to the bottom of the sea to settle, it is likely that it is still a cave under the sea, but with such a large population, it should not be possible to live with the Naga people anymore, but there should still be a connection." ”

Mr. Cicada said: "Don't guess if you don't say what the inscription says, let's find the artifact components, when Mr. Xiangxiang came here, it is likely to be just in time for this mushroom spirit to return to the depths of the ground, maybe he will have a record of the whereabouts of this mushroom spirit." ”

Mr. You Guang said: "Old ghost, do you still remember the sarcophagus in the underground labyrinth of Wugongbao? Mr. Elephant hinted above that he later left the Demon Refining Trail and went to the waters around the Six Poison Island, hoping to use the abundant water spirit and elephant resources in the sea water to achieve Elephant Fusion, which is a more powerful technology than the Qingming Elephant Fusion Transformation, since it is connected to the sea, will Mr. Elephant also go to the sea from here?"

Mr. Cicada thought for a moment and said, "Old ghost, can you stop guessing? Hurry up and find the artifact components, and you will know everything you should know by then." ”

"Well, the old ghost has a point, let's find the artifact components!" So Mr. Yuguang sacrificed the statue of Liren, and everyone followed it into the holy well.
