.Jia stood at the bow of the boat and let out the air. After staying in the cabin for a long time, she felt that she was a little moldy.

I slept in the "flagship" guest room last night. As expected, the comfort level was much better, at least the smell was not that strong. In the crew cabin of the merchant ship, even though Jia Yi used magic to blow it many times, there was still a lingering musty smell and a faint fishy smell.

But they have set out again now and are going to sleep in their original cabin tonight. There is nothing they can do with the "Green Hole".

The teachers and the others stayed on the green cave and began to arrange magic circles to monitor the entire green cave. If a monster with huge size or extraordinary magic fluctuations appears, it will release a signal and remind the academy to pay attention. I originally wanted to seal the entire cave, but later I thought about it and sent students to patrol every few months, giving students some opportunities to exercise.

Moreover, the entire closure is too expensive. It is better to save money to do a few magic experiments. The higher the magic power, the more money you do. It is said that at the legendary level, every time you start the magic array, you will consume tens of thousands of gold coins. Of course, every mage is willing to bear this cost, but there is no chance.

The teacher and the others were all staying on the cave. Although Jiayi gave a solution to explore the outlet of the underground river, there were still many discussions to really achieve it, and these had nothing to do with Jiayi and the others.

The people who found that the cave had nothing to do, so they could only move forward and continue searching for the lakes and looking for potential dangers.

Moreover, Jiayi still owed Queenie a meal of fish and didn't make it. Although the keel bone fish she retrieved was broken into fish meat by Jiayi, it was not used to make it for her. It is still left in the ice storage on Jiayi's boat and it seems that it has been forgotten.

Queenie didn't say that, and Jiayi just thought it was forgot.

Jia held a dark stone in one hand, which was covered with gaps, densely packed, like a sponge, but the gaps were much larger. However, although there were many gaps, the stone did not appear too light and could not float on the water surface. It seemed that the holes inside were all connected.

This stone was left to Kazui by Queenie and was broken off from the wall of the "green hole".

It seems that the failure of the sonar is related to this. When she saw the dense gaps in the cave walls, she brought a piece of it and threw it to Jiayi. After all, the sonar was Jiayi's own invention, and he was still very interested in why the sonar failed.

But I think it should be not just a matter of stones, otherwise the creatures in the cave would not be able to detect them.

Kaichi held the stone in front of him, and reached out to fire a sound wave at the stone. Although Kaichi used sonar props most of the time, there were also corresponding spells called "Kaichi's Bat Ears", but the effect was not as good as the magic props he made.

Sure enough, the sound waves reflected by the stones are much weaker, with an intensity of about one-fifth. Although they are not completely unable to reflect sound waves, it proves that the reflection of these stones on sound waves is very poor. There are other factors underwater that work together, so it is possible that they do not return.

......

When they discovered the green cave, they were already near the west coast and continued sailing for more than a day. Finally, they saw the west coast. The white bone they encountered on the island on the first day of departure was the water from Xi'an, and then they went to the place close to the east coast, and eventually died on the island.

When they arrived in Xi'an, it meant that their voyage had ended halfway. Next, they had to take another route, pass the largest Sanshan Island, and return to the academy.

On the way they came, they were actually not far from the north shore of the lake, so they walked almost in a straight line. On the way back, they had to detour through several islands, but the way back was much farther.

"Let's dock and go to the shore to repair it." Xiusli came to the bow of the boat, looked at Xi'an vaguely in front of him, and said loudly.

After saying that, he used the badge to communicate with Pascebai and notified the other party.

They have not been to land for several days. At the beginning, they didn't think that they missed land very much now.

Several boats slowly approach the shore. The lakeshore and the coast are different. Most of the lakeshores are steeper and the waterline of the boat is not too deep. So be careful, there is no problem with shore, but the coast is different. Generally, it is a beach or mudflat, which is relatively gentle, especially if there are fluctuations and tides. If the sea boat wants to dock, it will be stranded.

A group of people got ashore, and there was no people here at all. It was just a primitive jungle, with thick fallen leaves covering the ground and vines everywhere in the woods. It was very difficult to get out of a road.

Fortunately, the climate in the college is close to the sub-cold zone, and it is still early spring. Although the woods are chaotic, they are not like the legendary tropical rainforest. People cannot pass through it. Although there are many dead branches and leaves on the ground, they are not inaccessible.

When he arrived on the shore, Jiayi became active and said actively: "I'll go and find out if there is anything to eat."

"Why are they so active?" Seeing Jiayi turn around and leave after he said something, Seusli was still a little surprised, "Can they eat?"

Paserbai shook his head: "The tradition period has not passed yet. Are you stimulated? It is specially prepared for us?"

"Maybe it was for the sake of the future. Their traditional period is about to pass and it will end tomorrow." Lana said.

She understood Jiayi and the others' ideas, probably to hide some, and waited until the traditional food of the academy was eaten. After all, it was on the boat now, except for fish, the rest of the food was not rich.

"Jiayi, where are we going?" Trudy didn't react yet, but just subconsciously followed Jiayi, "Even if we hunted any prey, we can't eat it."

"Are you stupid?" Maggie couldn't stand it anymore and said to him, "Our tradition period will end the day after tomorrow. It's not too much to leave a little food we found. I can't eat it today, so I can just wait for a day tomorrow."

Trudy suddenly realized: "I said, why are you all so active? Jia shouted one by one and all ran out."

There are five freshmen in their team, including Jiayi, Trudy, and Machi, Ship 16, Jade and Mado, Ship 15, and there are no new students on some ships, because there are only six grades in total, and there are definitely not enough scores for two people in each grade in a row.

They walked along a small path deeper, saying it was a small path, but in fact it was a little less grass and trees, and it should be a path that wild beasts often walk on.

Jade walked aside, looking at the dead grass and leaves on the ground. Only a small number of trees on the tops had just begun to sprout, and it looked very deserted: "This season, there is nothing good."

"It's really nothing. At this time, there's not much meat for wild animals." Jiayi sighed a little, "But if you look for it more, you can always find something, at least there will always be a little mushroom."

There were actually few mushrooms at this time. The weather was too cold, but not at all. And although it was a little earlier, the forest was covered with trees, and the temperature was slightly higher. Some wild vegetables grew. Although they were not long, they could barely be said to be tender.

After walking a long way, Jiayi saw a large stone in front of him, covered with fungus-like things, and some of them looked like kelp roots.

Jia hurried forward a few steps, looked at the "wood fungus" on the big stone in front of him, and said, "This is a stone ear, a type of lichen, which can be eaten."

"Stone ears? I have only seen wood ears." Jade also came over and picked a piece of stone ears. "So, the ones that grow on the wood are called wood ears, and the ones that are on the stone are stone ears?"

"Maybe, it looks almost the same." Kaichi also reached out to pick a small piece of stone ear.

Although stone ears and fungus look similar, they are not the same thing. Stone ears are symbionts of fungi and algae, while fungus is fungi, so fungus is parasitic on wood, while stone ears survive through algae photosynthesis before they can grow on stones. There is also a type of earth ear, which is a kind of cyanobacteria that can photosynthesis.

Although these three things look a bit similar, they are not the same thing.

Jiayi then threw the earth ear into his mouth: "Well, there is no problem, it's the earth ear."

He once practiced the technique of identifying medicine and was able to distinguish the properties of medicine through his tongue. Later, he became a wizard and his tongue became even more powerful. Moreover, because he had to take too much, he became resistant to ordinary toxins.

He tasted the stone ears and confirmed that they were not poisonous before he decided that they were edible. The fungi in the forest were not easy to distinguish, and many of them looked similar. Sometimes, even some common fungi were easily identified.
