Xu Xin walked to the window and looked outside the tree house.

Although his eyesight is no longer so strong, Xu Xin's hearing is now extraordinary and he can clearly hear the movements around the tree house.

He heard the cry of the little pangolin under the tree house, as well as the chirping of various insects and birds, but other than that, there were no sounds from animals.

Without yesterday's super vision, he could no longer see things in the distance clearly, but he still remembered that one of the treehouses of other survivors he had seen before was in the east direction. He decided to go all the way east,

Go find the survivor's treehouse.

Since the distance is so close, the tree house over there should be owned by the people in Jungle Area 188.

But before that, he still had to take care of some things around the tree house.

Looking at the lake next to the tree house, the lake is rippling in the wind. On the map, there is no red dot showing the location of the lake.

Because Xu Xin has eaten blue-level resources, her ability to withstand water pressure has increased and she can now explore deeper into the lake.

Also, the yellow patch in the field of vision a hundred meters away from the tree house is the alchemy material. It’s time to dig it out and see what it is.

He planned to go down to find the concubine first to dig up materials.

"Hey!" It could be seen that Xu Xin was about to go out, so he also climbed up from the sofa and quickly climbed onto Xu Xin's shoulders.

Xu Xin rubbed Coco's little head, took Coco out together, and came to the concubine's cave under the tree house.

A circle of red berry bushes has grown around the entrance of the hole, full of fruits. Xu Xin used green-grade fertilizer to ripen it last night in order to cover the entrance of the hole. It looks much more comfortable this way.

Coco was immediately attracted by the red fruits and jumped down to pick the fruits to eat. Xu Xin slipped into the hole.

Concubine Ai was lying in the hole, and the two little guys next to her had just eaten and were lying on the ground with their bellies in the air, twisting their bodies slightly.

Good guys, these two little guys...are they a little bigger? Xu Xin stepped forward and picked up one of them.

Concubine Ai just glanced at him and didn't stop him.

He weighed it, causing the little guy in his arms to scream twice. Sure enough, it was much heavier!

The growth rate of the giant beast bloodline is really not slow, I really look forward to them growing up.

"My beloved concubine, come with me. I need you to help me dig a place." Xu Xin put the little guy down and said to her beloved concubine who was lying on the ground.

Concubine Ai made a sound as clear as a bird's chirp, stood up, and said yes.

Xu Xin crawled out from the hole, followed closely by his beloved concubine, and the two little guys also climbed out following their mother.

"Ugh!" Coco looked at the two little guys in surprise with a small mouth. There were still berries in his mouth that he had not swallowed. He felt that these two little guys would soon be bigger than him!

As soon as the little guys came out, they were pushed into the hole by my beloved concubine. They were well-behaved and did not come out again.

With Aifei and Coco, Xu Xin came to the vicinity of the yellow light. The yellow light was obviously emitted from the ground. Looking closer, it was not even shallow, at least five or six meters deep.

"This is it. Dig down. There should be something underneath." Xu Xin also took out his shovel.

Concubine Ai immediately started digging at the location pointed by Xu Xin. The scattered soil caused Xu Xin, who was about to swing the shovel, to stop his movements.

Good guy, the digging speed is really fast. He even took out the shovel to help, but it was completely unnecessary.

Seeing his beloved concubine completely plunged into the hole, Xu Xin put away the shovel. He would only be doing a disservice.

While it was digging a hole, Xu Xin walked around.

This place is nearly two hundred meters away from the tree house, outside the protection range of the heart of the plant. Except for the yellow light shining in this area, there is no other yellow light around.

It seems that only that area around the tree house contains alchemy materials.

He walked around again near the entrance of the cave with the mutated plant heart. Unfortunately, the cave disappeared together with the mark on the map.

Why? Who filled it in?

Xu Xin stepped on the original location of the hole and dug a few times with a shovel. There was thick soil underneath.

strangeness……

But it's a pity that he probably won't be able to go to the place where Ji Chaoyang knows the secret.

Xu Xin turned around twice more and returned to where her concubine was digging a hole. At this time, a hole about one meter in diameter had appeared on the ground, and there was the sound of digging from inside, but it was not digging.

Instead, it's like chiseling out stone.

Coco jumped off his shoulder and jumped directly into the hole.

Soon, the sound of digging stopped, and Xu Xin looked into the cave.

Not only did the yellow light representing the alchemical materials appear in front of me, but there was also the green light representing the color grade.

Green-level materials have been dug out!

At this time, Coco crawled out of the hole with a black thing in its mouth, then spit it on the ground and stuck out its little tongue. The sides of its mouth were black, and the hair on its body was also black.

Stained with some black.

Xu Xin picked up the fist-sized black pieces spat out by Coco.

【Obtain coal*1】

[Coal (green): A very efficient furnace fuel that can improve the melting efficiency of the furnace and is also one of the indispensable raw materials for refining steel. 】

The notification sound made the corners of Xu Xin's mouth curl up.

It's really coal, that's great! With coal, he can make steel blocks!

Xu Xin slipped directly from the entrance of the cave.

Aifei has stopped digging, and it has dug out a lot of space below. Xu Xin discovered that the area under his feet is all black coal mines!

"So many! This is too much!"

The cave was filled with coal that Ai Fei had dug up during the excavation. Xu Xin immediately collected the coal.

【Obtain coal*367】

Good guy, it only took a long time to dig, and so much has been found!

Xu Xin took out his pickaxe and swung it down. With a "click", the coal mine on the ground shattered and more than a dozen pieces of coal were scattered.

It's stable, there's a lot of coal shipped, and with this coal mine, he can refine steel!

A steel fire requires 25 pieces of coal and 1kg of mutant vine juice. He originally thought that it would consume a lot of materials and might not be able to be mass-produced. Unexpectedly, the output of this coal was ridiculously large!

Moreover, there is no need for him to do it himself. Concubine Ai can produce hundreds or even thousands of coal just by digging for half a minute!

As for the mutant vine juice, he still has a lot of it, and although he gave them some of the bloody thorn vines last time, there is still a lot left. After collecting all the juice, another few hundred kilograms will not be a problem.

"My beloved concubine, dig a little more!" Xu Xin directed her beloved concubine.

Aifei continued to use its sharp claws to mine the coal in the cave. Soon, the amount of coal in Xu Xin's hand reached 1,000 pieces.

"Okay, oh, by the way, dig the hole a little wider, otherwise you have to climb up and down every time." Although the hole with a diameter of one meter is enough for my wife to get up and down, for a man like him who stands and walks,

It's still too small. This is a mine he will come to frequently in the future, so of course it needs to be handled better.

After making the entrance of the cave larger, Xu Xin walked out of the cave. His scales had turned pitch black.

Xu Xin, who had been lying at the entrance of the cave and looking in, could see that Xu Xin, dressed in pitch black, came out of it, was stunned for two seconds, and then covered his mouth with his little paws, as if he was laughing.

"You little guy!" Xu Xin angrily lifted Coco onto his shoulder, "You don't even look at yourself. There is no hair on your body that is not black!"

"Hey!" When Ke Ke heard Xu Xin say this, he immediately shook his body, the black powder scattered, and the hair on his body immediately became shiny again.

I really envy Ke Ke’s body that can be very clean without taking a shower.

Carrying thousands of pieces of coal, Xu Xin quickly returned to the tree house. Instead of rushing to refine the steel fire, he went to the lake to clean it first. His wife also played in the mud by the lake.

Roll around and wash the black ash from your body in the unique way of pangolins.

Standing in the shallow water by the lake, looking at the deep and calm center of the lake, Xu Xin considered whether to go down now and have a look.

Now that his ability to withstand pressure has become stronger, he should be able to collect the green ore at a depth of forty meters.

"Hey!" Coco suddenly called out by the lake, her voice a little anxious.

...Is there danger in the middle of the lake?

Xu Xin's pupils shrank, she retreated from the lake, and asked Coco standing by the lake: "Is there any danger in the lake?"

"Hey!" Coco nodded firmly.

After receiving a positive reply from Coco, he looked at the map and saw that there were no red dots. It seemed that it was probably the giant anaconda in the middle of the lake. Could it be that the giant anaconda will return after the second stage?

Probably not... Even if teamwork is possible in the second stage, it would be a bit exaggerated to deal with a giant anaconda that is extremely huge and can dive into the water. This guy cannot be dealt with without large thermal weapons!

In short, diving in the center of the lake is temporarily unavailable.

Taking one last look at the seemingly peaceful but deeply dangerous center of the lake, Xu Xin turned and left.

Back in the tree house, Coco ran to communicate with Silver King Mimi, while Xu Xin came to the alchemy room again, clicked on the production list of the alchemy synthesis station, and found Steel Fire.

[Steel Fire: Add the refined iron block to the furnace together to smelt the same grade of steel block. Requires mutated vine juice*1kg, coal (green)*25]

He immediately clicked on refining.

Although it is called steel fire, it is not fire, but a black viscous liquid, which is somewhat similar to the universal alchemy material. He filled it with a reagent bottle, and a bottle of steel fire was completed. Next, he only needed to combine it with the iron block.

Pour them together into the furnace to make steel blocks!
