That trace is very faint, it seems to have been left a long time ago, how many years have passed, this trace has gradually disappeared under the strong vitality of the big tree, and now there is only a faint trace left, if it weren't for Yun Yi's extraordinary eyesight as an acquired ninth-order martial artist, he really couldn't find this faint trace, and the other martial artists in the exploration team didn't notice it.

Looking at the long trace, Yun Yi felt that this mark was not left by the claws of animals, but like a wound caused by a sharp weapon.

How could there be such traces on an isolated island on the sea, wasn't he Yunyi the first human to land on the island?

Yun Yi didn't know, just a trace couldn't prove anything, maybe Yun Yi guessed wrong.

The team continued to move forward, from time to time there were various years of medicinal materials were discovered by the low-level martial artists in the team, making the whole team more and more active, ordinary sergeants also wanted to find medicinal materials, but their eyesight was not as good as that of the martial artists, and there were all kinds of dangers in the jungle, they could only stay in the team honestly, otherwise the medicinal materials had not been found, so they threw their own little lives here first.

In addition to the fact that some of the medicinal materials that were found at the beginning were dug up, because the number of medicinal materials found on Yunyong Island was increasing, Yunyi did not let people dig out the medicinal materials, but only left obvious marks on the place where the medicinal materials grow, and then established a medicine garden on Yunyong Island in the future, and then transplanted all these medicinal materials into the medicine garden.

More than halfway through the morning, Yun Yi and his team had gone deep into the island for about five miles, and there were not many animals found on the island, but there were quite a few birds, and of course, there were all kinds of poisonous and non-poisonous insects on the ground.

The dense woods made the four warriors who opened the way tired of swinging their swords back and forth, and directly replaced a group of warriors to replace them and continue to open the way, and the warriors in the team were willing to open the way, after all, the warriors who opened the way were the easiest to find medicinal materials.

At the same time, Yun Yi was more and more surprised in his heart, Yun Yi was not surprised to find a large number of medicinal materials on the island, including ginseng and Ganoderma lucidum for about three hundred years, you must know that ginseng and Ganoderma lucidum are of great help to the improvement of the strength of martial artists, especially if Yun Yi wants to be promoted to congenital, with Yun Yi's martial arts talent, if he can use more high-year medicinal materials, then Yun Yi's promotion to innate speed will also be accelerated.

It's a pity that the Yunhua Yun clan has only been inherited for more than two hundred years, and the highest vintage medicinal materials in the Yun family's medicine garden can only be more than two hundred years, and the number is so small that it can be talked about, although the Yun clan is rich now, but if you want to buy high-year medicinal materials from the outside world, it is simply impossible, even if it is a good force with the Yun clan, no matter how much the Yun clan spends, it is difficult to get high-year medicinal materials, but now, just a small island in the sea can find high-year medicinal materials.

It is conceivable that with Yunyong Island, not only will Yun Yi's promotion speed be accelerated, but the strength of the Yun clan will also increase rapidly.

Improving strength is important, but now Yun Yi is even more surprised by the faint traces left on the trunks of some big trees, from the first trace found, the deeper he goes into the interior of the island, the more traces Yun Yi finds.

"There must have been people living on Yunyong Island before, and they were still warriors." Such an idea appeared in Yun Yi's mind.

There are only traces left a long time ago, all of which are about to be smoothed out by the years, but there are no new traces, obviously, there were people living on Yunyong Island before, and now there is no one else on Yunyong Island except for the Yun Clan's fleet.

At noon, the exploration team stopped to rest for a while, and the team members took out the dry food they carried with them and ate it, the food of ordinary sergeants was mainly flour cakes and salted dried fish, and all the warriors carried were dried meat and dried fish, because only meat could allow the warriors to quickly recover their strength.

Yun Yi ate some jerky, then took out a ginseng that looked to be about thirty to forty years old, washed it with water a little, and Yun Yi ate it directly.

Now the artificially planted 100-year-old ginseng does not help Yunyi much to improve his strength, and the wild ginseng of this year is not as good as the artificially planted 100-year-old ginseng, and can only be eaten by Yunyi as food.

The small number of medicinal herbs of lower age that had just been picked were also thrown by Yun Yi to the warriors in the team, although the medicinal herbs were small, but the power contained in them was much more than that of meat of the same volume.

After a short rest, the physical strength was almost recovered, and the team continued to pull out, with various surprises, and the team members were already familiar with marching in the jungle.

Wow! Wow!

Yun Yi stopped, listened with his ears pricked up, and saw that Yun Yi stopped, and the entire exploration team also stopped.

Wow! Wow!

"It's the sound of water." Yunyi identified the source of the "whooshing" sound.

This is almost the middle part of Yunyong Island, how can you hear the sound of water?

This can only show one problem, there is a water source on Yunyong Island, and there is a very high probability of fresh water.

There are fresh water resources, which is very important, ships sail in the sea, the most important thing is food and fresh water, food can be solved by catching fish, fresh water is a little difficult, if fresh water resources are found on Yunyong Island, then Yunyong Island is really suitable for living, otherwise Yunyi can only rely on other methods to produce fresh water, such as heating seawater to collect water vapor, transporting fresh water from land, establishing collection devices to collect rainwater, etc.

"Get out of there." Yun Yijian pointed in one direction and ordered.

"No!"

The opener was given the order to change the direction of the path, and the exploration team moved towards the place where Yunyi found the water source.

Wow! Wow!

As they got closer to the water source, the other warriors heard the sound of the water.

Closer, closer, the warrior who opened the way could even see through the gap in the jungle that there was a lake in front of him, a lake in the middle of the island.

A warrior swings his sword and chops off the branches, and the warrior's movements stop, and the turquoise lake appears in front of him.

The area of the lake is 40 to 50 acres, and according to the amount of rainfall in the sea, the lake can store enough fresh water for tens of thousands of people.

Seeing that the warrior who would not let the way of the lake stop his movements, his eyes were already on the other side of the lake, where there was a wooden house crawling with plants.

Someone on the island?!

No, Yunyong Island may have been inhabited before, it was a long, long time ago, and now the humans on Yunyong Island are only the people brought by the Yun Clan's fleet, and the people who once lived on Yunyong Island, maybe he or they have left Yunyong Island, or they may have died on Yunyong Island.

Yun Yi walked to the front of the group, scooped a little water from the lake with his hand, and dipped his tongue lightly, well, sweet water (fresh water).

"Li Feng and Wang Yu, the two of you return to the shore station, tell Wen Wei that fresh water has been found here, and ask him to send someone over to fetch water." Yun Yi pointed to the two martial artists and ordered.

"No!" Li Feng and Wang Yu received the order, turned around and ran along the opened up road towards the shore.

"The rest of the people continued to move on, around the lake, to the other side of the lake." Yunyi continued to order.

"No!"
