Li Long tried to put a few black eggs into the machine.

"Second level + one corpse core, five corpse cores in the second level.

"High value items can be used to exchange for basic materials."

Several lines of prompts are displayed on the machine's screen.

"I almost lost my life to get the things I got. I thought they were so valuable, so I could only exchange them for some basic materials?" Li Long was a little disappointed.

It is not very difficult to collect these basic materials when going out.

Don't take too much risk. With the help of space bags, you can easily collect these basic materials.

But then again, for Li Long, these basic materials are indeed very important to Li Long now.

For example, if you change enough materials to make the purifier, then it can purify the food.

Eating purified food in the future will no longer damage your health.

Only after eating food and drinking water can you have enough energy to continue to explore and find more food, drinking water and medicines.

Given his current situation, if he does not recover as soon as possible, it will still be very dangerous to go out tomorrow.

Either exhaust your physical strength or forcefully replenish your physical strength, resulting in aggravation of pollution and lowering your health value to zero.

Therefore, the purification function is exchanged earlier, which is crucial for him to survive in the Yin world now.

Li Long called out the redemption menu on the screen.

After some adjustments, I found that the basic materials that can be redeemed are enough to exchange for a purifier, and there are many more.

After Li Long exchanged the materials, he exchanged enough materials for a purification machine without hesitation.

The above shows that it is an LV1 purifier, which can only purify food and drinking water with a pollution index of 10.

It is enough for Li Long at this stage. Most of the pollution indexes of food and drinking water he found outside are below 10.

The purifier looks like an oven.

Li Long doesn’t have to worry about how the electricity comes from.

Anyway, the initial redemption machine and the lights in the room were all powered.

Carefully took out the oven...the purifier, and Li Long placed it on the ground.

Then, from the space bag, a bag of biscuits and a bottle of mineral water with an excess pollution index were put in.

Press the button.

The red light of the purifier warns, and a line of words appears on the screen.

“It takes a unit of wood essence to provide purified energy.”

"It's really not that simple." Li Long complained, then reached out and pointed out the four words "wood essence".

A prompt popped up again on the screen.

“The wood essence needs an LV1 workbench to be made.”

Li Long had to come to the exchange machine again.

After the purifier prompts, the exchange machine also provides redemption of the workbench.

It seems that some equipment must be redeemed first, and other equipment is needed during use before redemption will be unlocked.

Li Long hurriedly checked the materials needed for the workbench.

The surplus value of the black egg is enough to exchange for a workbench for LV1.

Of course, Li Long exchanged without hesitation.

The LV1's workbench is about the same size as a redemption machine, but it looks like a table with a cabinet below.

This machine that is similar in size to a redemption machine or exceeds the redemption machine is not spit out from the hole in the redemption surface, but is condensed into the room after the redemption is completed.

Li Long came to the workbench, operated the screen, and made the essence of wood.

The screen prompts that wood is needed.

This is not a problem.

Li Long has enough balance in the exchange machine to exchange for the required wood.

After redeeming some wood, Li Long stuffed the wood into the cabinet below the workbench according to the requirements of the workbench, then turned on the production button and selected the wood essence on it.

The workbench still did not start working, but a winch wheel was extended from the cabinet, requiring Li Long to rotate the winch wheel so that the workbench could produce the essence of wood.

"I'm going to do cool labor." Li Long had no choice but to turn the winch wheel.

This is a very physically exhausting thing.

Fortunately, Li Long now has a certain physical reserve.

Half an hour later, when Li Long's physical strength was about to turn red, the essence of a unit of wood was finally produced.

Li Long took out the wood essence from the unit from the cabinet.

The size of a matchbox, which looks like a wood, is actually heavier than iron!

Li Long deeply doubted that the so-called essence of wood is actually compressing the wood with high pressure.

According to the requirements of the purifier, Li Long stuffed the wood essence into the fuel silo behind the purifier.

Finally, the purifier started working.

Five minutes later, the bag of biscuits and mineral water was successfully purified to below the pollution index of 5.

After using a watch to check and confirm that there was no problem, Li Long ate biscuits and drank mineral water.

When I was extremely hungry, I felt that this was the supreme delicacy in the world.

The wood essence has not been consumed.

So Li Long put some food with an excess of the pollution index into it.

After the purification, Li Long had a full meal and then lay down on the bed.

After eating, I wanted to go to bed again.

Actually, I woke up before mainly because I was too hungry.

Li Long set the alarm clock on the seven o'clock in the morning.

It was dawn at seven o'clock, and the night ghosts dispersed, and Li Long could go up to the outside world.

There was a lot of supplies piled up above his top cover, and it was not good to be seen by other anchors who participated in the challenge, so they had to pack them in quickly.

Just as he was about to sleep on the wooden board, Li Long remembered that as long as there were enough materials, the exchange machine could exchange for a better wooden bed.

The wooden board is laid on the ground, it is very damp and very hard. If it can be exchanged for a more comfortable bed, it will recover much faster after sleeping.

Found the wooden bed option on the redemption machine.

To be precise, it is not a better wooden bed.

Instead, it upgrades the current wooden bed.

Wood, a small amount of metal, and a few kilograms of fabric are required.

The clothes taken off the corpse are all fabrics.

Unfortunately, all the fabrics collected by Li Long were on the top cover.

The surplus value of black eggs is no longer enough to exchange for the fabric raw materials needed to upgrade the wooden bed.

I can only wait until dawn tomorrow.

...

It's seven o'clock in the morning.

After being woken up by the alarm clock of the watch, Li Long felt good except for shoulder pain and back pain.

After checking the physical attributes, they have basically recovered to more than 90%.

The shoulder injury seems to have healed a lot. It seems that in addition to being hungry and thirst faster than the Yang world, the recovery speed of physical injuries is also faster than that of Yang world.

The reason for back pain is that this bed is too bad.

Hurry up to the ground and take down the collected resources.

Li Long opened the top cover and turned it over to the ground.

I packed all the resources in a space bag, and made some concealment around the top cover, and then I returned home.

There are a lot of clothes peeled from the corpse in the space bag.

These things do not take up much weight, so Li Long collected them more.

Put it in the redemption machine, just enough for upgrading the bed.

So Li Long pressed the button to upgrade the bed.

The wooden boards on the ground are actually not considered real beds, they are directly LV0.
