This holy well is very deep, there are four holes at the bottom, connecting four dark river waterways, fortunately there is a statue to guide the way, otherwise it would be a waste of time to choose the wrong one.

The waterway that led them down was also very steep, and Yu Yunluo said, "I don't know where the other three waterways will lead?

Su Yu said: "Even if there is, there can be no cities around those holy wells, and it is a fact that there is only one city on each layer of the underground water world." ”

"You're right...... "Accustomed to the form of a divine beast, Yu Yunluo still can't adapt to the humanoid form of the beast."

Without saying a word, they dived five miles along this waterway until they finally entered a huge cave filled with water again, with a phosphorescent kelp jungle and the ruins of an aquatic mushroom city hidden in it, no doubt that this was the second layer of the underground world.

The statue of Liren dived straight to the holy well in the center of this layer of the city, and everyone followed closely behind, Mr. You Guang said: "It seems that the artifact component is impossible in this layer of the city, should we directly follow it and continue to dive, or take a look in this city?"

Honggu said: "Let's take a look at the buildings on the side of the holy well, maybe there are records that are different from the previous floor." ”

"Well, this city is a relatively early city in the process of migration of this mushroom spirit, and the history will be relatively small, maybe more details will be recorded, let's go to the pyramids first. "Mr. You Guang summoned a statue and swam to the pyramid first.

This time he quickly finished reading the inscriptions on the pyramids, and swam to the palace again, and Honggu chased after him and asked, "Sir, what do the inscriptions on the pyramids say?"

"It's nothing special, it's much the same as the above, it's still the immigrants from the lower cities who came here in what year and month, and when the city was completed in what year. Mr. You Guang landed on the edge of the stone pillar forest outside the palace and began to look at the inscriptions on the stone pillars.

He browsed quickly this time, and as soon as he finished reading it, he swam directly to the temple, and Honggu chased after him and asked, "Sir, is there any new information about these stone pillar inscriptions?"

Mr. You Guang said: "If you want to say that the biggest difference from the records of the above cities should be these inscriptions, but they only talk about the inheritance of the throne and the major decisions and events that affect the clan, which are of little help to us in finding the artifact, and it is not of much significance to understand the details of the origin of this mushroom spirit." The only thing that is noteworthy is the relevant accounts of their exchanges with the lower cities. ”

Honggu said: "In other words, after the city was built, the lower city was still inhabited, and it was not completely abandoned?"

In fact, outside the palace of the upper city, a very important decision was recorded, which is not recorded in the records of this layer, that is, the mushroom spirits of the nine-layer underground water world unanimously decided to abandon the city and move upward, which is the bottom of the mine under the snake cave. Mr. Yuguang landed on the edge of the stone pillar forest outside the temple and began to look through the inscriptions on the stone pillars.

He still saw it quickly, and this time he didn't wait for Honggu to ask, so he said: "The myths told here are similar to the ones above. ”

"Where is the little difference?Is there a record of how this mushroom spirit lived underwater for a long time?" Although Mr. Cicada's speculation that this mushroom spirit has the same aquatic abilities as an underwater mushroom is almost the only plausible explanation, Honggu still wants to get tangible evidence.

Mr. You Guang said: "It's just a little more detailed than above, in fact, we have guessed, but we have not said how they can live underwater for a long time." Let's go to the third floor. ”

So they dived into the holy well, and at the bottom of this holy well there was only a downward waterway, almost vertical, and they dived two miles in it, and the waterway turned a corner, and extended down for more than ten miles with a relatively gentle slope, and finally they came out of the waterway again, and entered a huge water-filled cave, the bottom of which was covered with a jungle of giant algae, and many stone buildings were hidden.

The statue still dives straight to the holy well, and it can be seen that the artifact component is still not on this level.

"On each floor of the city below, I will take a look at a few architectural inscriptions next to the holy well, don't disturb me among you, if there is any problem, I will talk about it on the way to the next layer of the city. Mr. Yuguang summoned the statues, still browsing them in the order of pyramids, palaces, and temples, and then beckoned the others to dive into the holy well.

After entering the waterway, Honggu asked, "Sir, have you made any new discoveries this time?"

Mr. You Guang said: "Except for the records outside the palace, each floor is different, the records of the temple and the pyramid are all similar, there is nothing new to discover, let's go to the next layer as soon as possible." ”

This mushroom spirit has lived in every layer of the underground world for 3,000 years, and for 27,000 years, their beliefs and architectural styles have not changed significantly, and Yu Yunluo has long since dispelled the idea of visiting the entire city.

Starting from the third floor, every time he descended to the first floor of the city, Mr. You Guang would quickly read the inscriptions on several buildings next to the holy well, and then beckon everyone to sneak into the holy well and continue to the lower city.

Moreover, from the fourth floor to the seventh floor, the standing figures all fell straight towards the holy well, which shows that the artifact component is very likely to be in the underground water city on the ninth floor.

Mr. You Guang quickly browsed the inscriptions on the building next to the seventh floor of the holy well, and beckoned the others to sneak into the holy well and go to the eighth floor.

Because in the first few layers, the only new discovery was the appearance of the record of the Qingming mine on the fifth layer, and there was nothing else, so everyone didn't expect any new discoveries on the seventh layer, and no one asked again.

Unexpectedly, Mr. You Guang took the initiative to speak this time: "Why can this mushroom spirit live underwater for a long time, there is an answer at this level." ”

Everyone else was shocked, and Honggu said, "What's the answer?"

Mr. You Guang said: "The cicada flower ghost is only half right, when they are resting, they can indeed absorb nutrients with the help of the mycelium in the sediment at the bottom of the water like underwater mushrooms, but when they are usually active, they rely on the algae in their bodies. In fact, they are like lichens, forming a kind of symbiotic relationship with the algae. ”

Mr. Cicada said puzzledly: "In the lichen, the algae and the fungus coexist in order to provide them with water with the help of the fungus, but these caves are full of water, so why should the algae coexist with the mushroom spirit for the sake of water?"

Mr. You Guang said: "There is no answer here, but it is simply said that the Xuanzao and the mushroom spirit coexist, so that the mushroom spirit can live in the water for a long time, if you want to know the real reason, I am afraid you have to go to the bottom." ”

When everyone came to the eighth layer, the statue still dived straight to the holy well, and Mr. You Guang said: "It seems that the artifact component must be in the underwater city on the ninth layer, do we still need to read the inscription on the eighth layer? ”

Honggu said: "I have seen every layer above, why bother omitting this layer? ”

"Okay. So Mr. You Guang quickly browsed the relevant inscriptions of the three core buildings next to the holy well again, and then beckoned the others to dive into the holy well and go to the ninth layer of the underground water world.
