On the huge body of the giant ancient beast, the Ghost Faced Sky Spider directly killed fourteen corpse-eating insects with the power of thunder.

A total of fifteen green crystals and seven corrosive venoms were obtained before and after.

"A'Zhu, we must move faster. If we delay for a long time, we may cause additional problems!"

"Squeak!"

After the Ghost Faced Sky Spider responded, it got busy again.

Pieces of the giant ancient beast's meat were cut and quickly put into the storage box.

This giant ancient beast looked huge, but in fact it didn't have much edible meat. In addition, part of the meat and internal organs were eaten by corpse-eating insects, leaving even less for Chen Changan.

Half an hour later, the storage box contained more than 1,700 pieces of meat from the giant ancient beast, and only a huge skeleton was left in place!

If it were the meat of an ordinary ferocious beast, these more than 1,700 portions would not be enough for Xin Yue and the Black-armored Turtle King to eat for a long time, but it was the meat of a giant ancient beast. Even Xin Yue, who had an astonishing appetite, could only eat one portion.

That's almost enough, so there's enough for them to eat for a long time!

Chen Changan also asked the Ghost-Faced Sky Spider to try to cut off the skeleton, but no matter how hard the Ghost-Faced Sky Spider tried, it could not leave any scratches on the bones.

Looking at this hard skeleton, Chen Changan felt helpless. It was too big and could not be taken away without being divided.

After trying to no avail, they did not delay any longer, but changed direction and headed straight for the Black Snake Cave.

"Is this... still mining?" Xin Yue blinked.

"Life, life, you have to work since you were born. This is the true meaning of life!" Chen Changan nodded.

"What about you!"

"Of course I still have my work to do!" Chen Changan said meaningfully.

"Tch!" Xin Yue rolled her eyes.

When they arrived at the entrance of the Black Snake Cave, Chen Changan did not let Xin Yue follow him.

He knew that Xin Yue was afraid of the cold, and before the Black Ice Silkworms inside had been "cleaned" last time, he took the Ghost Faced Sky Spider into the Black Snake Cave.

However, one person and one beast turned the Black Snake Cave upside down, including the bottom of the Black Pool, and found no trace of the Black Ice Silkworm.

In the cave at the bottom of the Black Pond, the cocoons of the Black Ice Silkworms have also disappeared!

"What a pity, these dozens of points of experience are just gone!" Chen Changan shook his head and said.

At that time, the Ghost Faced Sky Spider was already in a weak state and was unable to use its skills to destroy the remaining Black Ice Silkworms.

After Chen Changan left the safe house, he kept using his heartbeat to keep time. Two and a half hours had passed since the transaction time he and Fang Yu agreed upon.

The only material for upgrading the second-level safe house is ore, which is in short supply at this stage. Chen Changan looked at the prices and found that they were relatively high. Even if he went to Zhang Yao to buy them, they wouldn't be cheap. It would be better for Xin Yue to do it and have enough food and clothing.

"Still digging iron ore and copper ore?"

"Upgrading the safe house is necessary to make the place where you live safer!" Chen Changan said righteously.

"I mine, what about you?"

"Of course I am responsible for security work. If danger occurs, I can respond in time!"

Xin Yue concluded her words and finally shook her head helplessly: "I want a green crystal stone!"

Chen Changan did not hesitate, and directly took out a green crystal and threw it to Xin Yue.

The simple psychic mineral pickaxe instantly glowed with light green light after being embedded in the green crystal stone.

Xinyue carried the psychic mining pickaxe and walked towards the cave wall.

The mining pick was raised high and then brought down hard.

"bite!"

Sparks flew everywhere, and eight pieces of iron ore fell to the ground.

"this……"

Although Chen Changan rarely mines, he also knows that this piece of ore requires at least a dozen knocks.

For the average person, it takes two to three minutes at the fastest to dig a portion of the mineral. If you are weak or have ordinary tools, it may even take more than 20 minutes to dig a portion!

And Xin Yue's one stroke will be eight copies, and ten strokes will be eighty copies!

"A born miner, if you don't mine, you will be a loser!" Chen Changan said with emotion.

Xin Yue ignored Chen Changan and didn't stop at all. He knocked more than a dozen times in succession, and a hole was dug out of the wall in front of him!

Originally, Chen Changan expected that it would take five or six hours of work, but with Xin Yue's full firepower, he could finish it all in half an hour.

Five hundred parts of iron ore, five hundred parts of copper ore!

"Where to go next?"

"Explore west for a while and see if you can pick up any treasure chests!" Chen Changan said.

Even if he goes back now, it is impossible for Fang Yu to prepare the four hundred mulberry trees, so he will simply continue to explore.

It would be even better if you can encounter ferocious beasts of the second and third grades.

Chen Changan's beast master was upgraded after a gap of more than 300 levels, while the Black Armored Turtle King was still at the second-level mid-level.

The Black-armored Turtle King slowly walked westward, and Chen Changan tried to draw a simple map in his mind.

"Safe house! There should be someone there!" Xin Yue pointed to the southwest.

After walking not far, Chen Changan and others discovered a human safe house.

"Xiaoyue, you and Xiaolu are waiting here. A'Zhu and I will go and take a look first!" Chen Changan warned.

He knows that although ferocious beasts are dangerous, they are far less dangerous than the unpredictable human heart. It is not clear whether the opponent is a friend or an enemy, so naturally he should be cautious!

"A'Zhu, let's go!"

Chen Changan said hello, jumped to the ground, and the Ghost Faced Sky Spider quickly followed.

One man and one beast were getting closer and closer to the safe house. Chen Changan looked at the structure of the safe house and judged that it was a first-level safe house, which proved that this man still had some strength.

"Why is there someone lying at the door!" Chen Changan froze and crouched behind a huge stone.

"A'Zhu, take a look and be sure to pay attention to safety. If you find any danger, withdraw immediately!"

"Squeak!"

The Ghost-Faced Sky Spider dodged and ran towards the safe house.

"It's a dead man!" Chen Changan saw the person lying on the ground in front of the safe house through the perspective of the Ghost-Faced Sky Spider!

After the Ghost Faced Sky Spider inspected the area and basically confirmed that it was safe, Chen Changan walked out from behind the boulder and came to the body to inspect it.

This man looked relatively young. He had scratches on his chest and legs that were deep enough to show the bones. No corpse of his war beast was found.

The door of the safe house was open. Chen Changan walked in and took a look. There was some water and food piled on the floor and on the wooden table.

He collected all the usable things inside, then walked outside the house and dug a shallow pit on the west side of the safe house.

"It was fate that we met, and I took so many things from you, so let me just let you rest in your grave!"

Chen Changan dragged the man's body to the pit and buried it.

"I hope if I encounter misfortune, there will be people passing by..."

Chen Chang'an and the Ghost-Faced Sky Spider walked some distance westward and found the corpses of five humans.

Three of the corpses had obvious scratches on them, and the corpses of their war beasts were also found.

In addition to harvesting some water and food, Chen Changan found four more treasure chests with Xin Yue's help.

"We've been out for a long time, let's go back!" Chen Changan patted the Black Armored Turtle King's thick back.

"Crickle!"

This entire journey has been explored, so the Black Armored Turtle King returns much faster.

More than half an hour later, Chen Changan's safe house came into view.

"Xiao Lu, stop!" Chen Changan said in a deep voice.

Looking from a distance, the pale golden wall is covered with deep scratches.

"The safe house was attacked by a ferocious beast?" Xin Yue frowned slightly.

"Let's observe here first!" Chen Changan did not rush into the safe house to investigate.

After a while, there was still no movement in the direction of the safe house.

Chen Changan asked A'Zhu, who was the most agile, to go check it out.

"Squeak!"

"It's safe, let's go there!"
Chapter completed!
