At the bottom of the unknown python cave, Chen Changan was hammering the ground in the center with all his strength.

Within ten minutes, a gleam of silver light loomed through the gap dug by Chen Changan.

"There really is a treasure chest!"

Chen Changan was overjoyed and sped up his movements.

He is now an intermediate beast master, and his body has been strengthened to a great extent!

I also took Xuanbing Fantasy Lotus and other exotic herbs and gained a strength bonus.

The strength bonus of 110 points is equivalent to the strength of a second-grade ferocious beast. Under normal circumstances, you will not feel tired after digging ore for half a day.

But now, Chen Changan was sweating profusely, and the green light on the handle of the psychic mineral pickaxe became weaker and weaker.

"This green crystal is so fast to use!"

After Chen Changan replaced a green crystal stone, he continued digging deeper without taking a break.

It was not until half an hour later that Chen Changan dug out the two treasure chests in the ground.

[Hidden information: This is a second-level silver treasure chest, which requires a green crystal to open! 】

[Hidden information: The box contains three-level safe house upgrade blueprints, spiritual fluid, and locust crossbow! 】

“Finally I saw the upgrade diagram of the Level 3 safe house!”

"Spirit-inducing liquid, with it you can practice the third level of the second volume of the Beast Control Technique!"

The items in this treasure box have a very important role for Chen Changan.

He directly took out a green crystal stone and embedded it in the groove of the second-level silver treasure chest.

A flash of light flashed, and Chen Changan opened the treasure box and took out the drawings and a bottle of liquid placed inside.

After learning the lesson from last time, Chen Changan was not in a hurry to use this spiritual fluid, but planned to return to his safe house!

So I put the three items into the storage box.

Every time he comes out, he has to take the Qingyu Cold Iron storage box with him. Although it is very troublesome, there is no better way!

After all, space containers are so rare!

After packing the items in the first box, Chen Changan turned to look at the second box.

The silver light on this box is more solid, so he has higher expectations for this box!

[Hidden information: This is a level three silver treasure chest, which requires two green crystals to open!]

[Hidden information: The box contains Ba Xia Shield and the third remaining volume of Beast Control Technique! 】

"Two spar?"

For the first time, Chen Changan encountered a treasure chest that required two crystals to open, but there was only a groove on the top of the treasure chest!

He first embedded a green spar stone, and with a flash of light, the green spar stone instantly turned into white powder.

Chen Changan did not hesitate, blew away the powder in the groove, and then inserted the second green crystal stone.

"Creak!"

The treasure chest opened by itself, and Chen Changan took out the two items inside.

I originally thought that the Baxia Shield would be at least as tall as a person, but what I took out of the box... was only about the size of a palm, and had a plastic texture, like a low-quality toy.

[Baxia Shield]: Made of dragon bones and the shell of the Baxia Turtle, it has extremely high defensive capabilities and requires crystals to activate. It will have different effects depending on the quality of the embedded crystals!

(Identification result: Purple Terrarium. Additional: Can provide extra shield to absorb attacks from ferocious beasts below level 4!)

[Hidden information: Processed with the essence and blood of ancient dragon turtles, it can be upgraded to Tyrannosaurus Shield, which can be embedded with crystal cores to improve Tyrannosaurus Shield's defense capabilities!]

“Although I don’t know the effect yet, it looks great!”

Chen Changan touched his chin and put away the third remaining volume of Ba Xia Shield and Beast Control Technique.

"It seems you are not useless!"

"When I find a new war beast, I will release you!"

“One less meal of braised rabbit head!”

As Chen Changan spoke, he grabbed Cangri Rabbit's ear with one hand and held it in his arms.

Then the Black Armored Turtle King curled his tail and pulled Chen Changan onto the turtle's back.

Soon, one person and three beasts returned to the safe house.

There are only two animal dens in the animal pen outside the second-level safe house. Now that there are Cangri rabbits, it is naturally not enough.

Although Cangri Rabbit helped Chen Changan find the treasure chest, in his subconscious, he still regarded Ghost Faced Sky Spider and Black Armored Turtle King as the main force.

As for Cangri Rabbit, you can at most make Braised Rabbit Head without it!

Treasure chests can indeed improve strength, but the number of treasure chests is too small, which greatly limits the role of Cangri Rabbit.

A war beast with almost zero combat power is not of much value to Chen Changan.

Therefore, this Cangri Rabbit will need to be replaced sooner or later, but the right one has not been found yet.

Chen Changan opened the animal enclosure and let the Ghost-faced Sky Spider and Black-armored Turtle King go in to rest, while he carried the Cangri Rabbit into the house.

War beasts can get the best recovery in the animal pen, and Chen Changan doesn't want Cangri Rabbit to take up their resting space!

"Bang!"

Chen Changan closed the door, then walked to the processing table and took out the upgrade blueprint for the level three safe house.

[Level 3 safe house upgrade drawings]: Bluestone bricks*500, Level 3 ferocious beast bones*20, Level 3 ferocious beast hides*10, Green crystal*5

(Hidden information: Since the impregnable state has been activated, this upgrade requires an additional green crystal*50!)

(If no special items are added when upgrading, the next level will be an ordinary level three safe house, and subsequent upgrades will no longer be able to activate the impregnable state!)

Seeing the content on the drawing, Chen Changan couldn't help but frowned.

There used to be many bones and skins of third-grade ferocious beasts, including the bones and skins of three-eyed beasts and the snake bones and skins of giant pythons.

However, due to the limited space in the Qingyu Cold Iron storage box, it was very troublesome for Chen Changan to carry it, so he did not bring it back.

"This...where can I find the body of a third-grade ferocious beast?" Chen Changan felt a little embarrassed.

There are not many other ferocious beasts on this Shanmian Island. The number of corpse-eating insects is comparable to cockroaches. As long as there are corpses, it won't take long for a large number of corpse-eating insects to gather. Even the bones will not be left.

!

Chen Chang'an recalled the map that Xin Yue had left. Except for the Black Snake Cave and the unnamed python cave, the lairs of other third-level ferocious beasts were relatively far away from here. A round trip might not even take seven or eight hours.

Even though both war beasts had been upgraded, Chen Changan did not dare to leave the safe house for too long.

"Go directly to the exchange and buy it. The third-grade low-level ferocious beasts are not difficult to kill. They should still be on sale!"

Chen Changan was really too lazy to make another trip, so he opened the exchange and browsed for a long time, but he didn't see a trading item related to the third-grade ferocious beast.

"No? No one will kill the third-grade ferocious beast, right?"

"Perhaps everyone has started to upgrade the level 3 safe house, and there is a shortage of materials for level 3 ferocious beasts!"

While Chen Changan was thinking, he received a piece of news.

"Brother Chen, do you have any green crystal stones?"

"How many green crystal stones!" Chen Changan replied directly.

"I need some, would you mind trading it?"

Fang Yu, a person who often burned, killed and looted, had never been truly polite to anyone, except Chen Changan.

"No problem, I need the bones and skins of third-grade ferocious beasts!"

"this……"

Seeing Chen Changan's request, Fang Yu was a little confused, and even felt that Chen Changan was playing a trick on her.

Having the bones and skins of third-grade ferocious beasts doesn’t mean that I can hunt third-grade ferocious beasts?

If I can kill a third-level ferocious beast, will I come to you to trade green crystal stones?

Fang Yu cursed in her heart, but did not show any displeasure.

"Brother Chen...I haven't encountered a third-grade ferocious beast yet..."

"Oh, I thought you had finished killing the third-grade ferocious beasts, and then you ran out of crystals!"

Chen Changan was a little disappointed, but after thinking about it carefully, it was reasonable.

After all, he spent a lot of time looking for third-grade ferocious beasts!

"So do you have diorite?"

"Yes, how many copies do you want?"
