Jiayi stood at the bow of the ship to let out the wind, and after staying in the cabin for a long time, he felt that his whole body was a little moldy.

I slept in the "flagship" room last night, and the comfort was much better, at least the smell was not so strong. In the crew cabin of the merchant ship, even if Kaichi blew it many times with a spell, there was still a lingering musty smell and a faint fishy smell.

But now they're off again, and they're going to sleep in their old cabin again tonight, and there's nothing left for them on the "Green Hole".

The teacher and the others all stayed on the side of the green hole, and began to arrange the magic circle, monitoring the entire green hole, if there is a large size or extraordinary magic power fluctuations of the magic beast appears, it will release a signal to remind the academy to pay attention. Originally, I wanted to seal the entire cave, but then I thought about it, and it would be a good thing to send students to inspect it every few months, so that students would have some opportunities to exercise.

And the whole closure is really too expensive, it is better to save money and do a few spell experiments, the higher the magic strength, the more expensive the experiments will be. It is said that at the legendary level, every time you experiment, you have to activate the magic circle, you have to consume tens of thousands of gold coins, of course, this cost every mage is willing to bear, but there is no such opportunity.

Teacher, they all stayed in the cave, although Jiayi gave a solution to explore the outlet of the underground dark river, but if they want to really realize, there are still many discussions, which have nothing to do with Jiayi and them.

The people who discovered the cave had nothing to do, so they had to move on and continue to search the lake for potential dangers.

And Jiayi still owes Queenie a meal of fresh fish that she didn't make, although the keel fish she retrieved was broken down into fish meat by Jiayi, but it didn't need to be made for her, and now it is still in the ice storage on Jiayi's ship, which seems to have been forgotten.

Queenie didn't say it, and Kaichi forgot about it.

Kaichi held a dark stone in his hand, and it was covered with gaps, dense, like sponges, but the gaps were much larger. However, although there are many gaps, the stones are not too light, and they cannot float on the water, as if the holes inside are all connected.

This stone was left by Queenie to Kaichi and was broken from the wall of the "Green Hole".

It seems that the sonar failure has something to do with this, she saw the dense gaps in the cave wall, and easily brought a piece up and threw it to Jiayi. After all, sonar is Jiayi's own invention, and he is still very interested in why sonar fails.

But come to think of it, it shouldn't just be a matter of stones, otherwise the creatures in the cave wouldn't be detectable.

Kaichi held the stone in front of his eyes, reached out and fired a sound wave at the stone. Although Jiayi uses sonar props most of the time, there are also corresponding spells, called "Jiayi's Bat Ears", but the effect is not as good as the magic props made.

Sure enough, the sound waves reflected back by the stones were much weaker, and the intensity was only about one-fifth of the same, although it was not completely unable to reflect the sound waves, but it proved that the reflection of the sound waves from these stones was very poor, and there were other factors working together underwater, and it was possible that there was no return.

......

When they found the green hole, they were already close to the west coast, and they continued to sail for a little more than a day, and they finally saw the west bank, and the white skeleton they encountered on the island they encountered on the first day of departure was from the water from Xi'an, and then went all the way to the place near the east coast, and finally died on the island.

When they arrived in Xi'an, it meant that their voyage had already ended a little halfway, and next, they had to take another route, passing through the largest Sanshan Island, and returning to the academy.

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

"Let's go to the shore and fix it up. Husley came to the bow of the boat, looked at Xi'an faintly in front of him, and said loudly.

After saying that, he used the badge to communicate with Paser Bai and informed the other party.

They hadn't been on land for a few days, and they didn't think it at first, but now they miss it very much.

Several boats slowly approach the shore, the shore and the coast are not the same, the shore is mostly steep, the waterline of the boat is not too deep, so be careful, there is no problem with docking, but the coast is not the same, generally a beach or tidal flat, relatively gentle, especially with the ebb and flow tide, if the ship wants to dock, it will run aground.

A group of people went ashore, there was no one on this side at all, it was a primeval jungle, the ground was covered with a thick layer of fallen leaves, and the trees were full of vines, and it was not easy to get out of a way.

But fortunately, the climate of the place where the academy is located is close to the subarctic zone, and it is still early spring, although the woods are cluttered, it does not look like the legendary tropical rainforest, people cannot pass through, and although there are many dead branches and leaves on the ground, it is not impassable.

When he arrived on the shore, Jia Yi also became active and took the initiative to say, "I'll go and see if there's anything to eat." ”

"Why are they so positive?" Seeing that Jiayi turned around and left, Husley was still a little surprised, "Can they eat?"

Passerbai shook his head: "The traditional period has not yet passed, have you been stimulated by anything?

"Maybe it's for the future, their traditional period is about to end, and it will end tomorrow. Lana said.

She somewhat understood Jiayi's thoughts, and it was estimated that she wanted to hide some of them, and wait until the traditional food of the academy was over, after all, it was now on the boat, and except for the fish, the rest of the food was not rich.

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

"Are you stupid?" said to March, unable to take it anymore, "the day after tomorrow our tradition is over, so let's not leave a little bit of food for the food we came out to find." If you can't eat it today, you can't wait for a day tomorrow. ”

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

There are a total of five freshmen in their squad, Jiayi, Trudy, and March are on the No. 16 boat, and Jade and Mado are on the No. 15 boat, which is not a few, and there are no new freshmen on some ships, because there are only six grades in total, and two people in each grade in one boat are definitely not enough.

They walked along a path to the depths, saying that it was a path, but in fact it was a little less grass and trees, which should be the animal path that wild beasts often walked.

Jade walked aside, looking at the dead grass and fallen leaves on the ground, and only a small part of the treetops had just begun to sprout, looking very deserted: "This season, there are no good things." ”

"It's really nothing, there is not even any meat in wild animals at this time. Jia Yi was also a little embarrassed, "But if you look for more, you can always find something, at least there will always be a little mushroom." ”

At this time, there are actually fewer mushrooms, the weather is too cold, but it is not completely absent, and although the time is relatively early, the forest is covered with trees, more humid and slightly warmer, and wild vegetables have also grown some, although they are not long, but they can barely be said to be tender.

After walking a little way, Kaichi saw a large rock in front of him, which was covered with fungus-like things, and some of them looked like kelp roots.

Jia Yi hurriedly stepped forward a few steps, looked at the "fungus" on the big stone in front of him, and said: "This is stone fungus, which is a kind of lichen that can be eaten." ”

"I've only seen fungus. Jade also came over and picked a piece of stone fungus, "So, what grows to the wood is called fungus, and what grows on the stone is the stone ear?"

"Perhaps, it looks pretty much the same. Jia Yi also reached out and picked a small piece of stone fungus.

Although the fungus and the fungus look similar, they are not the same thing, the fungus is a symbiont of fungi and algae, and the fungus is a fungus, so the fungus is parasitic on the wood, and the fungus survives through the photosynthesis of algae to be able to grow on the stone. There is also a species called the ear, which is a type of cyanobacteria that can photosynthesize.

These three things, while they look somewhat alike, are not the same thing.

Jia Yi threw the earth ear into his mouth: "Well, no problem, it's the earth ear." ”

He once practiced the art of discerning medicine, and was able to distinguish the properties of medicine through his tongue, but later became a mage, and his tongue became even more powerful, and because he had to eat too much, he became resistant to ordinary toxins.

He tasted the stone fungus and made sure that it was not poisonous, so he decided that it was edible, and the fungi in the forest were not easy to distinguish, many of them looked similar, and sometimes, even some common fungi were easy to identify.

It is said that in the south of Caiyun, many people eat wild mushrooms every year to make GG, and it is said that the people over there are also relatively familiar with various kinds of mushrooms.
