At this time, Feng Shijie also stopped looking, and said with a wry smile when he heard Lu Wan's words: "Captain, although gall alum is not valuable, this thing is accompanied by something very valuable, so my subordinates want to try to find out, but this requires professional knowledge, although I know some, but it is also half a bottle of vinegar, so I can only find it, it seems that I can only report to the association, and let them find someone to explore here." ”

"Valuable?" Lu Wan's eyes lit up after hearing this, "What the hell is it?" ”

Seeing everyone looking at him, Feng Shijie showed a smug smile and said: "Gall is also known as alum, wherever there is a bileite in the wild, there will generally be a copper mine, you see here in my hand, I can find so much in a short time, then it means that the copper mine is also near here, and it is even likely to be at our feet, but unfortunately I only know a little about this aspect, so I can't judge the location of the copper mine, and I don't know what its reserves are?" ”

Hearing that there was probably a copper mine under their feet, Lu Wan and the others were also very excited at first. The Central Plains Dynasty made copper into money very early, so copper in the eyes of people, in fact, is equal to money, although Feng Shijie can not find the location of the copper mine for the time being, but this does not prevent this great discovery, then they only need to report the news of the copper mine here, the rest is the business of the association, and once it is determined that this place has mining value, then they will get a considerable reward.

On the first day of landing on the Big Island, Luvan and his team failed to reach the place where the gold was produced, but they accidentally discovered a possible copper mine, although it was not known whether it was of mining value, but it was enough to make everyone feel a sense of joy. After all, whether this copper mine really exists or not, for them. This is all an excellent sign.

That night, the crew washed and cut the prey they had hit. In addition, some edible wild vegetables picked by Duo Ya were stewed, although the cooking method was very rough, but because all the ingredients were very fresh, the taste was also good, especially for Lu Wan and those who had been on the ship for a long time, it was a very rare delicacy.

In addition, it is worth mentioning that the prey that Lu Wan and they hunted the most was the big gray bird, which had very delicious meat. Whether it's grilled or boiled in soup, it tastes good, much better than chicken. And according to Duoya, when their tribe came to the big island, they mainly hunted this big bird named Rumodo, but Lu Wan felt that the local name of this bird was too awkward to eat, so he simply gave it a Chinese name, called Gray Crane, anyway, this bird except for the color and head. Otherwise, it does look like a crane.

Although the name of the gray crane was casually given by Lu Wan, it was indeed crooked, because the big gray bird they ate was indeed a type of crane. There were only minor differences in color and other things, and in later generations, it had a name. It's called the Australian crane, and it's the same as the kangaroo and platypus. All are creatures endemic to Australia, that is. The place where Luvan and them are now is the future Australia.

After walking for nearly a day, everyone was tired, so after dinner, most of them went to rest, but Lu Wan did not forget to arrange for someone to be on duty for the night, because according to Duoya, there will be some fierce beasts here, and when you are at the water's edge, you have to worry about the crocodile attack.

Speaking of the crocodiles on this big island, Lu Wan felt a little numb in the scalp, from the time of landing, they continued to encounter crocodile attacks, it is said that this huge beast generally lives near the water, as long as they do not get close, there will be no danger, but where they landed, it is a dense network of rivers, large and small lakes are everywhere, sometimes they have to pass through the middle of the two lakes, so there are not a few crocodiles encountered along the way.

Fortunately, there is Duoya as a guide, she reminded them early, so the crew are very careful, no one was injured along the way, and even killed two smaller crocodiles for dinner, the meat is more delicious than the gray crane, it tastes a bit like a soft-shelled turtle, but unfortunately it is too fierce, and it is not very easy to fight, otherwise it can be beaten more, and then canned food to take back to give away.

After a night's rest, the crew's energy from yesterday recovered, and they warmed up the broth left over from yesterday, and then Lu Wan hastily ate some of them, and urged the crew to continue on their way. However, during breakfast, there was a small episode, two younger crew members did not want to eat yesterday's leftovers, so they ran to the grass by the lake to touch the eggs of the gray crane to eat, this time is the breeding period of the gray crane, so after a while, let the two boys pick up two big bags of eggs.

However, after the two young crew members found out about this, she was very angry, and even quarreled with each other loudly, but fortunately, the two sides did not understand each other, so this did not continue. Later, after Liu Kata's translation, Lu Wan and the others learned that although Mo Libu hunted gray cranes and other animals, he only hunted adult animals, and did not hunt adult animals and animals in the breeding period, let alone eat bird eggs.

Moreover, the reason why they live on Sunset Island now is because the gray crane, which is the main food source of the tribe, is in the breeding period and is not suitable for hunting, so they have to live on the island until after the second month of the lunar calendar, and then return to the big island to hunt gray cranes. It is said that yesterday Doya didn't want Lu Wan and them to hunt the gray crane, but Lu Wan was a guest, and the number of hunts was not much, so Doya had no need to prevent it, but now that she saw that the crew didn't even let go of the eggs, she had to come out to stop it.

Hearing Doya's reason for stopping them, the two young crew members were a little unimpressed, but after hearing it, Lu Wan felt that it was understandable, Doya and their ideas were actually in the Central Plains, to put it bluntly, it was actually a matter of not trying to catch fish, so that these animals could reproduce from generation to generation, and they could also provide them with endless food.

Thinking of this, Lu Wan stepped forward to stop the other crew members from looking for the birds' eggs, and as for the two young crew members who had already brought back, they couldn't send them back, so they simply asked the cook to make egg soup, which Duoya was not happy about, but she did not object. And the crew also knew that they would need Doya's help to find the gold mine next, so they didn't take it very seriously.

Today's journey was almost a repeat of yesterday, and the grass that was more than one person tall could not see the situation ahead at all, and there was no road to take, but fortunately, Duoya judged the direction according to the lakes and rivers, and Lu Wan had a compass, so he was not worried about getting lost. It was not until noon that they finally walked through the grass to the foot of a low mountain.

This hill is full of rocks, and there is no soil for plants to grow, so there is not much vegetation on the mountain, only a bush in the east and a west, and there are obviously fewer weeds, and the grass is not as lush as that that grows on the flat land, and it looks like it is all malnourished.

Lu Wan and the others followed Doa up one of the hills, there was a small river down this hill, they walked up the river bank, until they were halfway up the mountain, they saw a huge cave, the whole cave entrance was more than two feet high, the inside was dark and unclear, and in front of the cave entrance, there was a flat ground formed by rubble, about the size of two basketball courts, and there were some traces of human activities on the field, it seemed that this cave had been inhabited before.

When Doya saw this cave, she was very happy, and ran into the cave with her flying machine to check it, but except for the feces of several animals, no animal took this place as her nest, which made Doya very happy, and beckoned Luwan to hurry up and clean the cave, this is where they lived tonight.

Seeing that Duoya seemed to be very familiar with this cave, Liu Kata asked Duoya, what is this cave for? As a result, Doya told him that this cave was the station of their Morribu on the big island, and whenever they came to live on the big island, the whole clan would live here, and Doya was born here, so this cave was her home to her.

After listening to Duoya's words, Liu Kata nodded understandingly. At this time, Lu Wan also walked over and asked Doya, "Doya, is the place where you found the gold here?" ”

After hearing this, Doya shook her head and said: "No, this is where we live, and the place where the gold was found is not far from us, we only need to climb over this hill, there is a canyon in the part of the mountain, and there is a small river in the valley, I found the gold on the bank of the river in the first place!" ”

Hearing that he had to climb over this hill, Lu Wan couldn't help but ask a little anxiously: "Since it is still so far away, why don't we continue to hurry until we have rested in that valley, and it is too far to live here." ”

However, Lu Wan's words did not convince Doya, she still insisted on living in the cave, because according to her description, although the valley was not far away, but there lived in the valley a group of fierce wild dogs, which were nothing during the day, but at night, they would come out to hunt, which was very dangerous, so they must not live in the valley.

Since Duoya said so, Lu Wan had to obey, after all, people are the guides, and thanks to Duoya along the way, otherwise they really don't know how many people will die?

It was now time for lunch, and everyone cleaned up the cave briefly, and then fetched water from the creek in front of the cave to cook, and it was noon, and there was no prey on the hill, so they ate all the dry food they brought from the boat. After a simple meal, because it was still early, Lu Wan left a few people to guard the cave, and the others went to the canyon in the back mountain with Duoya to check it out, and tried their luck smoothly, because they heard Duoya say that it was very likely that they would see a whole piece of gold in the canyon.
