"Brother San, you don't have to change the drawings of the building materials manufacturing table. I have many contribution points here. I just buy them and give them to you!"

Qin Xiaochuan suddenly remembered that he had 4,600 contribution points but was useless. He could buy some drawings from the building materials manufacturing station and give them to them. The remaining excess seemed to be able to be traded in the trade center.

"Ah? Why can I accept it, boss? I'm very embarrassed to help you sell water and earn commissions." The third brother of Yulong said embarrassedly.

"We are from the same tribe. If you treat me as your own, then accept it!"

Qin Xiaochuan spent 4,400 points of contribution to exchange eleven blueprints for building materials manufacturing stations, and then said to the tribe: "The tribe has given benefits. I will send each person a drawing for building materials manufacturing stations later, and you will save a lot of materials. This is also a gift for you to join the tribe. I hope everyone will unite and work together in the future to carry forward our rookie tribe!"

"Boss!"

"Old Qin is Old Qin, he is so generous!"

"Thank you, Brother Qin..."

Qin Xiaochuan's welfare is indeed good. The second and third-level materials are manufactured for a long time, so the materials have to be dug out from the outer island. It will take some time to get 400 points. The key is that these are all money.

Qin Xiaochuan sent the drawings to Lao Zhao, Leng Ye and five others one by one, and left another for Yue Ling, with five more.

"The rest will be put on the shelves!"

There are only two tribes in the entire server. Eliminate those building materials manufacturing blueprints that may be obtained through various channels, that is, twenty people will have blueprints, so this building materials manufacturing blueprint is a rare product like guns.

It costs about twenty silver coins to make up 400 contributions. Qin Xiaochuan sets the price of the building materials manufacturing platform blueprint at two golds. The more the technology tree goes up, the more complex and expensive the materials needed. The blueprint that has been completed before will no longer accept donations, so the contribution points will become increasingly difficult to earn. Selling this price is definitely a conscience.

Just like guns, the blueprint of the building materials manufacturing platform was immediately emptied as soon as it was put on the shelves. Qin Xiaochuan's funds instantly broke through the single digits and accumulated eleven or two golds.

Leaving the exclusive island of the third brother of Yulong, Qin Xiaochuan continued to search westward. With the help of his watch, all the exposed copper mines wherever he went were plundered.

It was getting late, and it was almost forty or fifty nautical miles after Qin Xiaochuan and his team came out. There was only one iron pickaxe left in the bag, and there were about seventy copper ores in the backpack.

"Boss, go back first. I feel it will rain tonight!" Buge looked at the dim sky.

"Okay, please turn around." Qin Xiaochuan was so tired today.

Buge shook his head and turned the speedboat over. Just as he was about to speed up, Qin Xiaochuan suddenly stopped him and looked along Qin Xiaochuan's right side. A large island suddenly appeared hundreds of meters away in front of them.

"When did this island appear? I haven't seen it when I came here just now!"

Qin Xiaochuan opened the chart and the sea water was located above.

Although it is only a few hundred meters away, the island is backed by the sunset and cannot see the outline clearly. Only vaguely see the buildings on the island, and there are many.

"Can you see clearly? Why do I feel that the island is shaking..."

"Boss, this should be a mirage!"

Mirage! Qin Xiaochuan immediately reacted, it seemed to be true, but this is too real.

Buge looked at the mirage and said slowly: "I once heard an old captain say that mirages will appear on the sea before heavy rain or in the hot sun. Where mirages appear, treasures will often be born, but they are also accompanied by danger. Only brave and wise people dare to explore."

"Treasure? Real or fake?" Qin Xiaochuan couldn't help but become interested when he heard these two words.

"I don't know either... maybe it's just a sea legend made up by the old captain."

Qin Xiaochuan looked at the island with golden light shining in the setting sun and couldn't help but shout, "Then let's take advantage of the moment, Buge, drive the boat over!"

"Boss, are you sure you want to go?"

"What are you afraid of? You have such good fighting skills. I have a gun. Thor is burly in body. It's no problem to fight one or two pirates alone."

Seeing Qin Xiaochuan eager to try, Buge had to rush over with all his strength.

Qin Xiaochuan took the opportunity to open his watch and check the information about the mirage. The information he obtained made him very satisfied.

It turns out that the mirage is indeed as Buge said, treasure and danger coexist because this mirage is actually the entrance to the copy!

Mirages occasionally appear on sea or on land, and this disguised copy will stay for an hour and disappear after an hour.

The mirage copies that appear each time are different. Some limit the number of people, while others can enter unlimitedly. However, this copy has one characteristic, that is, it is either dead or pass the level, otherwise it will not be possible to exit halfway.

The mirage is getting closer and closer. Qin Xiaochuan turns off his watch. The query function of the watch is like an encyclopedia, which allows Qin Xiaochuan not to miss any opportunity to improve his strength in vain.

When the speedboat broke through the light curtain, there was nothing in front of him, and the island no longer existed, and only the system prompt was still ringing.

"Ding! You have entered the Mirage Copy: Ghost Base!"

As soon as he turned his eyes, Qin Xiaochuan and the other two had already appeared on the big island they had seen before, and the beach behind him was a speedboat.

In front of Qin Xiaochuan, a pure reinforced concrete explosion-proof wall of up to four meters stretches out, wrapping the entire island facing the beach, like a huge military fortress.

However, the fortress seemed to have been destroyed because the concrete walls had been destroyed by artillery fire.

Moss is spread all over the wall, and not far away is the gate of the base, an alloy gate blocked by double-layer gates.

Qin Xiaochuan opened his watch and searched for four keywords of the ghost base, and a detailed introduction to this copy popped up.

This base was originally a front-line supply base built when the Eternal Federation conquered the world, and it stored a large amount of ammunition, fuel and logistics supplies.

After the Eternal Federation completed the unification of the world, it blew up the base, but then the growing Red Moon Pirates occupied the base and became the thief cave of the Red Moon Pirates.

Many years ago, a terrifying tsunami suddenly invaded here, submerging the entire island. When the sea water retreated a month later, the place was completely abandoned.

But in the following years, every time a passerby stayed here, he would disappear inexplicably, and rumors spread about it. Passing ships would avoid it, and even if they experienced a storm, they would not dare to go to the island. Later, this place was called the ghost base.

In fact, there are five transparent Red Moon Pirates sailors in this base. After the tsunami scraped them into the bottom of the water, a strange whale with a body of more than ten meters long and a jellyfish all over the body swallowed them in one bite.

In order to survive, the five people worked together to cut open the fish's belly and pierced the whale's head. They were contaminated with the whale's brain and their whole bodies instantly turned into transparent. Except for themselves, it was extremely difficult for the outside world to detect it.

The five people who returned to the island used their invisible ability to re-occupy the base and started a sneak attack on passing merchant ships.

This is the background story of the entire copy, which can be said to be quite weird, a bit like a poor person relying on mutation.

What made Qin Xiaochuan very interested was that if you complete the first kill of the ghost base dungeon, you can get the only NPC recruitment card: Ghost Team!

In addition, the watch actually gave a pass strategy. If it is a single person or a team member to enter the dungeon, you need to find the wheat flour hidden somewhere in the base, borrow the wheat flour to let the ghost team perform, and then kill it.

If it is a group, then rely on barrage shooting to force the Ghost Squad to submit. The system also specifically reminds that the Ghost Squad will carry a poisonous dagger, and as long as it is attacked by the Ghost Squad, it will be fatal.

But Qin Xiaochuan has a more direct way, his watch can detect any moving object.
Chapter completed!
