[Steel Spear: A spear made of steel blocks. Sharper than iron spears, it is the hardest and sharpest weapon of its class! Durability 1000. Requires 5 pieces of wood and 2 pieces of steel blocks.]
A purple-grade steel spear requires four pieces of blue-grade wood, one piece of purple-grade wood, one piece of blue-grade steel and one piece of purple-grade steel.
Taking out a blue-grade steel block and a [core of a low tree house], Xu Xin tried to put the two resources together.
[Use the core of the low tree house to upgrade the steel block to a steel block? ]
When the prompt sounded, Xu Xin did not hesitate and immediately chose yes.
The core of the tree house, which originally emitted a bright white light, suddenly shone brightly. Then, with his ability to identify, the blue light on the steel block gradually began to turn purple.
Eventually, the light at the core of the treehouse dimmed, transforming from a "night pearl" emitting a brilliant white light into an ordinary, pale yellow spherical stone. The steel block also completely turned purple.
[The core of the low tree house has lost its energy: The core of the tree house has exhausted all its energy and turned into an ordinary stone. Perhaps there is a way to recharge it with energy.]
Full of energy again! As expected, even if the energy core is lost, it can still be recharged!
This made Xu Xin overjoyed. If he could find this method, he could really produce purple-level resources on his own!
But how to charge it?
"The core of the tree house..." Xu Xin muttered to himself, "Could it be related to the parasitic tree house?"
He had looked at the functions of the parasitic tree house, and there was no option to charge the tree house core.
He suddenly remembered that when he was operating in Parasitic Tree House 01, Coco had been scratching the floor with its little claws. When he finally left, it was still scratching the floor, and he took it away directly, and it was a little reluctant at the time.
Xu Xin originally thought it was sharpening its claws, but now it seems that...
He didn't care about the purple-level weapons anymore, he could make them anytime anyway. He picked up Coco from the sofa and rushed to the parasitic tree house 01.
"Oh, oh, oh?" Coco was dozing off on the sofa when she was lifted onto Xu Xin's shoulders, her little head full of question marks.
"Help me find out later if there's anything special about the parasitic tree house."
"Ying!" After hearing these words, Keke was no longer sleepy. He waved his little paws and cried, as if to say that he had actually discovered it a long time ago, but was directly taken away by Xu Xin last time.
Sure enough, it was similar to his guess.
Arriving at the first floor of Parasitic Tree House 01, Coco jumped down from Xu Xin's shoulders, ran to the center of the tree house, and scratched the floor with her little paws: "Ying!"
Xu Xin was very familiar with this location. Wasn't this the location of the tree house's trunk, and also the original location of the tree house's core?
The parasitic tree house has no core, so it should be empty inside.
Do we need to pry open the floor in the center of the tree house and insert the tree house core in the original position of the tree house core?
Xu Xin touched the floor with his hand, but did not trigger any prompts to control the floor to lift up.
...Then chop it with an axe!
Anyway, it’s just a matter of removing a piece of tree house floor. He doesn’t even need to repair it himself afterwards. The tree house can recover by its own self-repair ability.
He did it right away. Pulling out the iron axe, Xu Xin struck the floor with it.
“Crack!”
Just like before, the Green-level Parasitic Tree House was completely unable to withstand the Blue-level Iron Axe. With just one strike, the floor in the center cracked. After a few more strikes, the floor shattered.
Xu Xin cleared the debris on the floor, revealing the situation underneath.
"really!"
The floor beneath the treehouse is different from a normal treehouse. A normal treehouse is a hollow trunk, with the core buried in the soil at the bottom. However, the trunk of the parasitic treehouse is solid, with only a hemispherical groove that is perfect for placing the core of the treehouse.
[Discover the parasitic tree house charging slot and unlock the core charging function]
Do I have to discover this core charging function by myself?
Xu Xin placed the [core of the low tree house] that had run out of energy. With a slight "click" sound, the core of the tree house just happened to be stuck in the hemispherical hole.
A faint white glow emanated from the already dim core of the tree house.
Xu Xin touched it with his hand. The core, which had become cold after losing energy, was now warm, like a hand warmer.
[Remaining charging time: 4 days, 23 hours, 59 minutes]
It really can be charged!
"Ying!" Coco also touched it, and finally even lay on it, showing a comfortable little expression, with her little tongue sticking out.
Xu Xin fell into deep thought.
Originally, the core of the tree house was used to provide energy to the tree house, but the parasitic tree house obtains its energy from the host tree house, so it does not need special energy from the tree house core. Instead, it can supplement the energy obtained from the host tree house into the tree house core.
This should be the principle of charging the core.
However... it seems that the host tree house, that is, his tree house, needs to provide more energy and the burden is greater. It is also unknown how many parasitic tree houses it can withstand at most.
Although five days of charging time is a bit long, the purple-level resources are worth the long wait.
If we have more parasitic tree houses in the future, we can mass-produce purple-level resources!
By the way, what would happen if a fully-energy core was placed on top?
