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

Although his eyesight is no longer as strong as before, Xu Xin now has extraordinary hearing and can clearly hear any movement around the tree house.

He heard the cries of the little pangolin under the tree house, as well as the chirping of various insects and birds, but there were no other animal sounds.

Without the super eyesight he had yesterday, he could no longer see things in the distance, but he still remembered that one of the tree houses of other survivors he had seen was due east. He decided to head east to find that survivor's tree house.

Since they were so close, the tree house over there must be owned by the people in Jungle Area 188.

But before that, he still had to deal with some things around the tree house.

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

Because he had consumed blue-level resources, Xu Xin's ability to withstand water pressure had increased, and he could now explore deeper into the lake.

Also, the yellow area in sight a hundred meters away from the tree house is the alchemical material, and it’s time to dig it out to see what it is.

He planned to go down and find his beloved concubine to dig up some information first.

"嘤!" Seeing that Xu Xin was about to go out, Ke also got up from the sofa and climbed onto Xu Xin's shoulders nimbly.

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

A circle of red berry bushes had grown around the cave entrance, laden with fruit. Xu Xin had ripened them last night using green-grade fertilizer. The goal was to conceal the entrance. It looked much more pleasant this way.

Keke was immediately attracted by the red fruits and jumped down to pick some to eat while Xu Xin slid into the cave.

My beloved concubine was lying in the cave. The two little guys beside her had just eaten and were lying on the ground with their bellies facing up, twisting their bodies slightly.

Wow, these two little guys... have they grown a little bit? Xu Xin walked over and picked up one.

The beloved concubine just glanced at him and did not stop him.

He weighed it, causing the little one in his arms, who had just finished a full belly of milk, to cry out twice. Sure enough, it was much heavier!

The growth rate of the behemoth bloodline is really fast. I am really looking forward to seeing them grow up.

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

My beloved concubine made a clear sound like a bird's cry, stood up and said yes.

Xu Xin crawled out of the cave, followed closely by his beloved concubine, and the two little ones also crawled out following their mother.

"Hmm!" Coco looked at the two little guys in surprise with her little mouth, still holding some berries. She felt like the two little guys were going to be bigger than her soon!

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

With his beloved concubine and Coco, Xu Xin approached the area of ​​yellow light. The yellow light was indeed coming from underground. Looking closer, it was not shallow at all, at least five or six meters deep.

"It's right here. Dig down. There should be something underneath." Xu Xin also took out his shovel.

The beloved concubine immediately started digging at the location Xu Xin pointed. The flying soil made Xu Xin stop swinging the shovel.

Wow, the speed of digging the hole was incredible. He even took out a shovel to help, but it was completely unnecessary.

Looking at his beloved concubine who was completely stuck in the hole, Xu Xin put away the shovel. He would only make things worse.

While it was digging the hole, Xu Xin looked around.

This place was nearly two hundred meters from the tree house, outside the protective range of the plant's heart. Apart from this patch of yellow light, there was no other yellow light around.

It seems that only that area around the tree house has alchemical materials.

He walked around the entrance of the cave where the mutant plant heart was. Unfortunately, the cave and the mark on the map disappeared.

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 can't go to the place where Ji Chaoyang knows the secret.

Xu Xin turned around twice and returned to the place where his beloved concubine was digging a hole. At this time, a hole with a diameter of about one meter had appeared on the ground. There was also a sound of digging coming from inside, but it was not digging the soil, but rather sounded like someone was chiseling stones.

Coco jumped off his shoulders and jumped directly into the cave.

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

Not only did the yellow light representing the alchemical materials appear before my eyes, but there was also green light representing the color level.

Green-level materials were dug out!

At this time, Coco crawled out of the hole with a black thing in its mouth, then spat it on the ground and stuck out its tongue. The edges of its mouth were black, and its fur was also stained with some black.

Xu Xin picked up the fist-sized black fragments that Coco had spit out.

【Obtain coal*1】

[Coal: A very efficient furnace fuel that can improve the smelting efficiency of the furnace and is also one of the indispensable raw materials for steelmaking.]

The prompt sound made Xu Xin's mouth curl up slightly.

It was coal, awesome! With the coal, he could make steel!

Xu Xin slid directly down from the cave entrance.

Ai Fei has stopped digging. A large space has been dug out underneath. Xu Xin discovered that the area under his feet is all black coal!
