30 minutes is not a long time, it is not a short time, and when the system prompt sound sounded in his ears again, Lin Feng's whole person became excited.

"Ding! The treasure hunt system has been successfully upgraded, and all functions are open normally!"

After this system upgrade, the following functions have been opened: 1. Points to increase the level of strength comprehension, 2. Small world to improve physical strength, 3. Exchange coupons for treasure exchanges, 4. The time to collect treasure chests has been shortened to 10 seconds. ”

"Ding! The intelligent housekeeper is cute and has obtained level 5 permissions. ”

......

A series of system prompts made Lin Feng inexplicable, and he subconsciously shouted in his mind: "Mengmeng, what is the situation now? What is the use of these functions that the system is open?"

"Hehe, master, these functions are very useful, you listen to me explain carefully, first of all, after the treasure hunt system is upgraded this time, the master can use points to improve the level of strength comprehension......"

As Meng Meng told the story, the more Lin Feng listened, the more excited he became, and the more he listened, the happier he became, he never expected that this time he would actually pick up the treasure!

First of all, points can not be used to exchange for treasures, but they can be directly used to improve the level of strength comprehension, the specific exchange ratio is: 100 points to increase the degree of strength comprehension by 1%.

Secondly, the treasures in the exchange center can only be purchased with exchange coupons, as for where to get the exchange coupons? Meng Meng said that this kind of exchange coupons can be directly issued in ordinary treasure chests.

Then, the small world can improve the physical strength, what is the small world? The special space opened up in the space ring with boundary stones is called the small world. And the size of the space in the small world directly determines Lin Feng's physical strength.

As for where to get the boundary stone? Meng Meng said that after opening the mysterious treasure chest, you will definitely get a boundary stone!

In the end, Meng Meng obtained the fifth level of permission. But when Lin Feng asked Mengmeng what permissions he had obtained, Mengmeng avoided answering and directly prevaricated Lin Feng with the word 'confidential'.

it!

What do you mean?

Meng Meng, who has obtained the fifth level of authority, can openly disobey the master's orders? If she gets a higher authority, wouldn't Meng Meng be able to rebel?

However, Mengmeng's next sentence dispelled Lin Feng's concerns: "Hehe, Mengmeng will never rebel, the reason why I don't tell the master is because Mengmeng and others want to surprise the master!"

"Eh, what kind of surprise?" Lin Feng asked subconsciously.

"Oops! Everyone said it was a surprise, and now if you tell the owner, how can there be a surprise effect later?"

"Oh, okay, then I'll wait for the surprise that Meng Meng brings. Lin Feng touched his nose and replied with a smile.

"Hehe, master, you better hurry up and open the mysterious treasure chest, right? The rewards inside are all random, and it depends on the master's luck. Meng Meng reminded.

"Okay! open the treasure chest immediately!" Lin Feng's eyes immediately lit up.

......

The mysterious treasure chest lying in the space ring, except for the different colors, is exactly the same shape and size as the other treasure chests.

However, just as Lin Feng set his eyes on the mysterious treasure chest, a detailed introduction also caught his eyes at the same time.

[Mystery Chest (Special): After opening this chest, you will definitely get 1 boundary stone, and you can also get three different rewards at random. Note: After opening the Mystery Chest, the system will randomly take back a permanent item from the host, please use it with caution. 】

I rub!

After opening the Mystery Chest, while getting the reward, the system will recycle a permanent item, which is a double-edged sword!

I saw Lin Feng quickly check the space ring, and then took out three props: a miniature reconnaissance plane, a spider silk glove, and a human skin mask.

That's right! Lin Feng currently only has these three permanent props, among which the miniature reconnaissance plane and the human skin mask are the most useful, and Lin Feng is certainly reluctant to throw away either of these two props.

"Mengmeng, if the prop is taken back by the system, can I still use the exchange coupon to buy this prop back again at the exchange center?" Lin Feng asked the question in his heart.

"I'm sorry, master, when a certain item is recovered by the system, the exchange center will also erase the item accordingly, so ......" Meng Meng replied regretfully.

"Okay, I see. Lin Feng nodded with a wry smile, and then stared at the three props in his hand for a moment.

Perhaps seeing Lin Feng's embarrassed expression, Meng Meng suddenly persuaded: "Master, after all, props are things outside the body, although they can bring temporary convenience to the master, they can't increase the master's own strength......"

“...... As long as the master becomes strong enough, when the time comes, these props will not be used at all! To put it bluntly, props are a kind of auxiliary tool, and the master can't live on auxiliary tools all his life, right?"

Mengmeng's words were reasonable, and Lin Feng couldn't find any words to refute, but after he hesitated slightly, he immediately said: "Mengmeng, I want to open this mysterious treasure chest!"

"Okay, master, please wait a minute......" Meng Meng suddenly became extremely excited.

Lin Feng: "......"

"Huh!"

I saw that the mysterious treasure chest lying in the space ring suddenly shook rapidly, and only three seconds later, the lid of the treasure chest automatically popped open, and a pile of shiny treasures jumped out of the box.

Quiet!

Very quiet surrounding!

I heard Meng Meng suddenly exclaim: "Ah! The master's luck seems to be a little bad, right?"

"Ah, bad luck, what treasures have been opened? Mengmeng, tell me quickly!" Lin Feng was a little anxious.

"Well, I'll see...... The owner received a total of 1,000 points, 1,000,000 gold, 1 voucher, and 1 boundary stone. Meng Meng replied truthfully.

"Hmm, it's okay, right? After all, four rewards were issued at once...... Lin Feng replied covering his forehead.

However, the owner's permanent prop, the human skin mask, has been recovered by the system. Meng Meng said cautiously.

Lin Feng: "......"

"Don't be sad, Master, Mengmeng still has a surprise to give to the master?" Mengmeng said to Lin Feng in a flattering tone.

"Mengmeng, what kind of surprise is it?" Lin Feng said speechlessly.

I saw Meng Meng say in an eager tone: "Master, you hurry up and use the boundary stone to open up a small world in the space ring, and then, Meng Meng will tell the master what the surprise is!"

"Oh, okay. Lin Feng nodded with a smile.

[Boundary Stone (Special Item): A magical stone that was born with the universe in legend, and when used, it can open up a small world in the space ring, which can accommodate all life species. 】

[Note: A boundary stone can only open up a maximum of 100 cubic meters of space, and the small world can be transformed at will according to the host's ideas.] 】
