"This reward is kind of interesting!"

Lei Chi collected 800 gold coins from the claim chest, used 100 gold coins to buy invasion insurance, and put the remaining 700 gold coins in the gold mine treasure chest.

Moments later, he used the [Password Chest Upgrade Scroll] to upgrade a gold mine chest into a password chest.

The password chest is slightly different from the gold mine treasure chest in appearance, with a small horn on the lid of the treasure chest, and its opening password allows up to six words, and the thunder pool is set to: "Meet the Emperor of the Thunder Pool!" ”

He personally tested it, this password treasure chest is very good, as soon as the password is spoken, the treasure chest lid automatically pops open, and the small horn on the treasure chest lid can also emit: "Please say the password", "Password error" and other prompt voices.

"Interesting, but this password chest is not good, if Zissinger invades again, I have to tell him to open the password......"

The opening password of the password chest can be changed at any time, Lei Chi studied it for a while, and after a while, he came to the side of the militia training camp, where he used the [Arsenal Construction Blueprint].

Quickly, right next to the militia training camp, a boxy building appeared.

The building is very similar in appearance to the militia training camp, and from the outside, it is a tower with an arch that opens up to a field the size of a football field.

As soon as Lei Chi entered it, he immediately received a system prompt.

"Ding, detect the camp information, the arsenal will open the automatic production line of [beret], and after mastering more equipment production technology, the arsenal can open the automatic production line of more equipment."

"Ding, the production materials of berets are all kinds of leather materials, open automatic manufacturing, make each beret requires 10 copper coins, the production time varies depending on the production material, the final product will be stored in the equipment treasure chest, please explore it yourself."

Lei Chi raised his eyes and looked at the two areas in the arsenal, and he slowly studied it.

The first area is the [Production Workshop], which is a hall with the four big characters "Production Workshop" floating above, in which there is a material treasure chest, a gold coin treasure chest, and an equipment treasure chest.

Three treasure chests are a production line.

The material treasure chest can store the crafting materials of the [beret], the gold coin treasure chest can be stored as the "production cost", and the [equipment treasure chest] is the place where the finished beret is stored.

The second area is the R&D Center, which is also a hall where there is also a treasure chest, which is the Funding Chest, where gold coins can be stored for research funds.

This [R&D Center] is a place to create and upgrade equipment independently, but in order for its functions to be activated, at least one "researcher" is required.

The researcher can only be served by NPCs, and the only ones that can be appointed at the moment are SpongeBob SquarePants and the wise elf Ah Mei.

The owner of the camp can issue a task of R&D equipment or upgrade equipment in the [R&D Center], and can assign NPC researchers to receive the task, but the researcher's research and development of equipment will cost research funds, and there is a possibility that the research will fail.

"It seems to be a place to burn money......"

After a moment's thought, Lei Chi set SpongeBob SquarePants and the camp elves as researchers.

"Ding, your camp assistant SpongeBob SquarePants has average ability, and has obtained a new title: Arsenal R&D Center Researcher (D level), you can gain experience by completing research and development tasks, and increase the title level to C-level, B-level, A-level, etc., the title level increases, and its R&D ability will be improved, please explore it yourself."

"Ding, your camp assistant Ah Mei has outstanding abilities and has obtained a new title: Arsenal R&D Center Researcher (S-Rank), you can gain experience by completing R&D tasks, and increase your title level to SS level, SSS level ......"

"Ding, there is no R&D task in the current R&D center, the research funding is zero, and the R&D work cannot be carried out!"

Lei Chi listened to the system prompt, and said in his heart that the wisdom elf Ah Mei is really powerful, and she is directly an S-level researcher, and it is estimated that her research and development capabilities are much better than SpongeBob SquarePants.

He researched it again and released a research and development task: [Crafting Ranged Weapons].

For this task, he planned to wait for the wisdom elf Ah Mei to unlock the [Faith Totem] technology before assigning it to it.

As for D-class researcher SpongeBob SquarePants, Lei Chi guesses that he will not be assigned a research task.

After all, its research capabilities are too poor.

"Research funds, save a gold coin first, and then talk about it when you have money...... There is still a shortage of gold coins, and I hope the system can lose more next time. ”

Lei Chi put a gold coin into the research fund treasure chest, and after a while, he left the arsenal and leisurely brushed up the defense tower arena.

Relying on the stunt of "Beast Tower Lurking", Lei Chi can be described as a lonely defeat in the defense tower arena, he has been winning in a row, and the arena rank is about to break through the expert level.

Time passed, and when the protection period of Lei Chi's secret camp ended, Zissinger arrived as promised.

Lei Chi prepared 30 Terran militia and 5 berets for him.

Zissinger easily killed the 30 Terran militiamen, didn't take the berets at all, kicked them away, and then went to the gold mines.

Lei Chi was wearing a silver tiger, riding a mechanical war horse with a timbre, and said: "There is a treasure chest in the gold mine, you need to give it up, and say to meet the Emperor of Lei Chi, it will be opened, remember, remember ......"

"Password Chest? Meet the Emperor Leichi? Kissinger smiled, "How could I say such a sand sculpture password!" ”

"There are over 700 gold coins in the password chest!"

"Do you think I'm going to give in for a little gold......"

Moments later, Žisinger left with 751 gold coins.

Lei Chi's loss this time is 30 militia fighters plus the 751 gold coins, and the system compensates for the claim chest worth 7194 gold coins.

From this treasure chest, Lei Chi opened a [First-Order Defense Tower Construction Blueprint], two [Password Treasure Chest Upgrade Scrolls], a [Defense Tower Mutation Scroll], 10 Terran slaves, and a full 3,500 gold coins.

"3,500 gold coins, there's money!"

Ray Chi quickly collects the gold coins from the claim chest, then finds SpongeBob SquarePants, who is polishing the mechanical warhorse, and pulls him into the altar of valor in the militia training grounds.

A moment later, Thunder Pool consumed a thousand gold coins, and the SpongeBob SquarePants standing above the altar flashed and became a hero, his size became much larger, almost as tall as Thunder Pool, with a red cloth strip tied around his head and a small yellow cloak behind him.

"It's attacking! One more skill? Is my 1,000 gold coins worth it? ”

As Lei Chi said this, SpongeBob SquarePants seemed to suddenly remember something, and happily ran down the altar, and in a short time picked up six berets and put them all in his equipment slot.

SpongeBob SquarePants' appearance has not changed, but with six berets equipped, it adds a total of 6 armor and 6 magic resistance.
