Wu Hui has no ore on hand and cannot use the furnace for the time being. There are some swords, armors, and stones specially recorded and engraved in the molds next to them.

And a metal sheet mold with several polygonal grooves. I don’t know what it is used for.

There are no written records here, and the weathering is so severe that even glasses cannot scan them.

However, Wu Hui estimates that mining in this round may be a very important point. These metal furnaces and molds will probably be used in the end.

Minerals formed by the precipitation of organic matter such as oil, natural gas, coal mines, metal minerals, and gemstones are probably the three main mineral types in the world. They are also one of the most primitive wealth for mankind.

Of course, various stones may also be considered minerals.

Among the yellow sand, Wu Hui dug out a piece of plate salt. After removing the sand on the surface, it was still the size of a palm. It was good, so at least it would have a flavor when cooking.

It was evening again, and the city had almost been explored. Wu Hui and Ren Yin shot two birds for dinner. It wasn't delicious, but they had no choice.

After a busy day, he didn’t eat much. This was Wu Hui’s worst time since he entered the survival game series.

There is no way, there is too little life in the desert. Water is the medium for life activities. Where there is a lack of water, there will always be few traces of life. Without life, there will naturally be no food.

"Get ready to go, rush to the next oasis today." Wu Hui pushed up his glasses.

Looking at the situation on the map, the next oasis is very large. I hope I can see large animals and fruits when I get there. The current food is still too lacking and monotonous.

Eating only meat for a long time is not good for the corpse. Of course, Wu Hui and Wang Xiaodie still have two bottles of potion left, so they can drink it when they can't hold on any longer.

They are on the road again. According to this progress, they may encounter the first pyramid tomorrow. There are seven in total, and they don't know what constitutes a successful exploration.

Pyramids are closely related to institutions, mummies, pharaohs and so on in people's minds.

Wu Hui had several guesses about what was in it.

On the way to the oasis, the map marked the location of a stone statue, and he planned to go there and see what it was.

In the desert, five huge objects of different colors and shapes similar to Easter Island stone statues stood on the ground. After confirming that there was no danger, Wu Hui took Wang Xiaodie and approached.

"Answer questions and gain knowledge."

"Difficulty is different, rewards are different."

"The gold statue is the most difficult, the stone statue is the easiest."

"If you answer incorrectly, you will be punished."

"When you're ready, let's start."

Uncoated stone statues, black iron-coated stone statues, bronze-coated stone statues, silver-coated stone statues, and gold-coated stone statues. Each of the five stone statues said five sentences in one sentence.

"Well, let's do it one by one." Wu Hui asked, starting from the ordinary stone statues without coating. This should not be too difficult.

"Who is Wang Xiaodie's favorite man?" Shixiu asked.

Wu Hui did not hesitate: "Me."

Wang Xiaodie: "Hey, hey, aren't you afraid of getting the wrong answer?"

Stone statue: "You answered correctly, this is your reward."

It shows a drawing with a stone talisman painted with a special pattern and inlaid with blue gem fragments.

Water-making sigil, magic stone piece*1, water mark gemstone fragment*1. After use, create one liter of pure fresh water.

"This is indeed a good thing. But in this game, you really have to be a miner." Wu Hui curled his lips and quickly accepted this.

Next, the iron stone statue.

"Please name the three emperors of the Northern and Southern Dynasties." the iron stone statue said.

"Emperor Liu Yu of Song Dynasty, Emperor Xiao Daocheng of Qi Gao, Emperor Wu of Chen and Chen Baxian." Such cold knowledge is not difficult for Wu Hui. He has a wide range of knowledge, a strong memory, and also likes to read history.

Of course, if you answer the question correctly, you will get a talisman.

Constant temperature rune: magic iron piece*1, cold mark gem fragment*1, fire mark gem fragment*1. The temperature change around you is slowed down for one day.

Copper and stone statue: "Please briefly describe the causes and consequences of the three turning points in the People's United War."

"The first turning point was during the Penrose generation, when the People's Alliance used electromagnetic weapons for individual soldiers for the first time..." This question is also relatively unpopular, and it has changed from an answer to a brief description. But it is also difficult for Wu Hui. Two consecutive questions are considered

For the history question, Wu Hui was lucky.

Fire rune: magic copper piece*1, fire mark gem*1. After use, it creates a fireball to attack the enemy.

According to the glasses scan, the fireball is roughly equivalent to a five-star five-element card. That's not bad, and it will be a great attack method in this game.

Silver Stone Statue: "One hundred prisoners have one hundred numbers. There are one hundred boxes placed in a house. Each box has a number from one to one hundred in shuffled order. Each prisoner enters the room in turn and each one opens it.

Half of the boxes are closed after leaving. The prisoners are required to take turns entering the room in order, and no communication is allowed during the process. If everyone finds their corresponding number, all will be released. But as long as one person is not found, all will be executed, and the prisoners can

Discuss before starting. Please tell me which strategy has the highest probability of survival."

"Wait a minute, this question is very long, can you read it again?" Wang Xiaodie was a little confused, but Wu Hui started to answer after thinking for a few seconds.

"Enter No. 1, open box No. 1 first, then open the next box according to the number in this box, then open the next box and so on." (For example, if you open box No. 1 and the number is 6, go to open box No. 6.

, open box No. 6 and the number is 88, then open box No. 88.)

This can increase the probability of 1 in 2^100 to about 31%.

(You can discuss the principle yourself. To put it simply, it means converting multiple independent events into one event, whether there is a large cycle of more than fifty digits)

Wu Hui's answer is correct.

Oasis Rune: Magic Silver Piece*1, Life Gem*1, Water Gem Fragment*3. After use, an oasis with an area of ​​9,000 square meters with fresh water and vegetation will be created on the spot. It can be used three times.

A good thing, but you can tell at a glance that it is difficult to make.

Next is the most difficult problem of the golden stone statue. Although some of the previous problems are not easy, none of them are difficult for Wu Hui.

Although the oasis rune has no lethality, it is very functional and can be used three times. Its value is equivalent to that of the six-star and five-element cards.

Then the answer to the golden stone statue may also be able to produce seven-star and five-element card-level consumables.

Producing this kind of thing yourself is definitely more cost-effective than purchasing it. Moreover, after the intermediate competition, Wu Hui's five-element cards were running out. The few seven-star cards were all played on Du Ziming.

Prepare for the last question.

"Please tell me the ultimate goal of your efforts to become stronger and how you plan to achieve it."

The golden stone statue did not change at all, but Wu Hui felt a pair of eyes staring at him, as if he was looking forward to his answer.
