Lin Yue looked at the contents of the silver treasure chest and was quite surprised.

It's okay to actually be able to open a map of underground ruins.

After opening it, Lin Yue quickly saw the underground ruins map marked "Area F" on the system panel.

This map can be enlarged or reduced according to his thoughts, and it shows the general layout inside.

"It seems...it happens to be the area I have been to? But the places I have been to only account for less than 0.1% of this map?"

Lin Yue was surprised to find that the places he had been to were highlighted on the map, while most of the places he had not been to were dark.

Moreover, the place he visited was located at the edge corner. The end of the passage to the Ice Lizard Cave was open and seemed to be connected to other areas.

Unexpectedly, this underground ruins is so big.

Lin Yue looked at the map and felt a desire to explore.

After all, he got a lot of good things there.

This is true whether it is the ores or the huge number of treasure chests.

Compared with the mutated creatures in the wasteland above, the slightly taller treasure chests in the underground ruins are more efficient.

etc.

Lin Yue made another bold guess.

If we say that the system puts all humans into a different world in order to select the "elite" among them, it gives everyone a game panel so that people can become stronger in the process of continuous exploration and fighting for survival.

Then opening the door to the secret realm is to allow humans to search for various materials on the earth in a few decades to make their living standards stronger.

Opening the door to the underground ruins will allow humans to get used to fighting, strengthen exploration and adaptability, and other abilities.

Is this possible?

Lin Yue suddenly felt that he should take a rest before going to the underground ruins. Anyway, there is no other difference between day and night underground.

Moreover, the system has not said how long the underground ruins gate will last, or how long it will be forced to kick out the rules.

If the storage space is enough, you can even stay in it for a long time without any problem.

Another thing that came out of the silver treasure chest was a high-end oven set. Lin Yue took it out and found that it was an iron thing with a larger capacity and a lid, and it was also equipped with a special place for seasoning.

Moreover, this set also comes with a hundred metal skewers, a grilling net, a small brush for brushing materials, and a blower and smoke exhaust device.

It can be said to be the ultimate ideal equipment for barbecue lovers.

He looked at the 11 copper treasure boxes on the ground and the gold treasure box.

No matter what you want to do next, let’s finish opening them first.

Having said that, this is the first time I have obtained so many copper treasure chests at once.

[You obtained: Area map fragments x2]

[You got: 4L of drinking water, windproof lighter x1]

[You have obtained: cucumber seeds x1, humus nutrient soil 6l]

[You got: Design drawing of large metal water storage barrel x1]

[You have obtained: wooden bed design x1, cooking oil x5l]

[You got: 5kg long-grain fragrant rice, apple x5]

[You have obtained: regional map fragment x1, 2.5l bottle of Rebi]

[You have obtained: wooden wardrobe design drawing x1, a waterproof mat]

[You have obtained: Hammer Design x1, Recliner Design x1]

[You have obtained: Iron Scissors Design Drawing x1, Iron Basin Design Drawing x1]

[You have obtained: first aid medical kit (small), area map fragment x1]

"It's so tiring to open the treasure box..." Lin Yue shook his hand and said again that this was simply a worry.

However, he also discovered that the items found in the copper treasure chests this time were similar to those usually found in copper treasure chests. They were almost all basic items related to life and survival.

Compared with the iron treasure chest, the quality and helpfulness to life are better.

Wooden treasure chests bring food and water, while iron treasure chests bring out the most basic survival supplies. Copper treasure chests go a step further and bring out some daily necessities and things that are slightly closer to enjoyment, as well as various designs.

Figures and area map fragments and more.

Silver treasure chests are higher-end and generally contain more critical equipment and special items.

A gold treasure chest...

Lin Yue had only given it out once before, and it was the special prize that ranked first in the system reward rankings.

The things inside are closer to high technology or even black technology.

Lin Yue took a deep breath and looked at the last remaining gold treasure chest in the middle of the room.

What will it produce?

[You have obtained: alloy shelter design drawing x1, small drone design drawing x1]

The air became silent for a moment, and Lin Yue's hands froze at the same time.

Wait, what happened when I opened it?

Alloy shelter design? And drone design?

Good guy, this is directly on the design drawing of a shelter that is much more advanced than now?

This can be considered a top-level configuration.

Originally, he thought that opening the treasure box would not reveal the shelter design, but now it seems that the level of the treasure box is just not high-end enough.

Alloy shelter design drawing... What alloy is it?

He picked up the light blue blueprint and used it.

【Alloy Shelter】

【Area: 60㎡】

[Requirements: Alloy (not limited to type) x60, wood x10, stone x10, iron block x30, glass (not limited to type) 2 pieces]

Ah this.

Sixty pieces of any type of alloy is fine.

Lin Yue looked at himself and found that the only alloy he had was duralumin alloy.

This was originally intended to be used in simple exoskeletons and robotic arms. Even this he received from the survivor named Zhang Lei.

He has really never received alloy, or in other words, he has never had a chance to receive it.

During the two visits to the secret place in Tokyo, most of the things I got were small and medium-sized electrical appliances, as well as various tools, supplies, etc. For example, Zhang Lei was directly affected by the luck of hard aluminum alloy when he came up, but he did not.

Wait, can we find that guy to deal with it?

Opening the group, Lin Yue directly searched for Zhang Lei's name among hundreds of thousands of people.

Oh, still alive!

Chat privately and ask to see if this guy has anything he needs.

"Zhang Lei, please reply if you are online."

It only took a few seconds for this private message to be sent, and Zhang Lei responded immediately!

Zhang Lei: "Damn it, did I read that right? Boss, are you looking for me?"

Lin Yue: "How much alloy do you still have?"

Zhang Lei paused for a while before replying: "Lin Yue, why do you need so much alloy?"

Lin Yue: "How many?"

Zhang Lei: "How much do you want?"

Lin Yue: "I want as much as you have."

Zhang Lei: “I’ll have as much as you want!”

After Lin Yue wrote "Are you sick" in the chat box, he thought about it and deleted it.

"You make a condition, and I'll accept it all."
