C523 Mixed material (1/2)

Lu Shan continued to excitedly place cups of squeezed fruit juice into the Upgrade Box, but unfortunately … However, there were no other materials that could be used to concoct life potions, which made him anxious.

Then, he accidentally spilled a glass of grapefruit juice that had not shown any reaction after testing it out on the table. Several of the cups had some grapefruit juice in them.

He could not help but have a headache seeing this … It didn't matter if he mixed the grapefruit juice with the juice since he had already tested the juice and couldn't use it to concoct the elixir of life, he could drink all the useless juice later and avoid wasting it.

But there were still quite a few cups of juice inside, and he hadn't tested them yet! Now that he mixed it with grapefruit juice, he didn't know if it would work or not. If not … He might have to squeeze out another glass!

Since it was already like this, Lu Shan had no other choice but to take another glass of lychee juice and put it inside the Upgrade Box …

”Unknown Potioneering Material (Unknown Grade) found. Host, please continue to place the appropriate material into the mixture. Use the material with uncertain functional grade. The properties and effects of the potion are unknown. Host, please proceed with caution!”

I'll go...” What the hell was this? How did he come up with a material of unknown grade and effects?

When Lu Shan first heard the system's notification sound, he was actually quite happy. However, when he heard that it was actually an unknown grade and unknown use of the ingredients, and also … When he didn't even say that this was the ingredients to concoct the Life Potion, he was stunned for a moment. Soon after … He realized that this was not because of the grapefruit juice mixed with the lychee juice.

Thinking to this point, Lu Shan's eyes lit up. He immediately picked up another cup of fermented flower juice that had just been tested a moment ago, yet did not have any reaction as he placed it into the Upgrade Box.

This really worked!

Lu Shan was finally sure. He reckoned that if the glass of lychee juice didn't accidentally splash into the grapefruit juice, it might not be suitable for concocting the medicine!

He then poured the other cups into the grapefruit juice as well. The fruit juice that did not react to the test were then tested by the Upgrade Box. Two of the cups did not show any reaction, while the last one had a hint:

”The Intermediate Health Potion materials have been found, please continue to put in the suitable materials for the preparation.”

I'll go...” This cup of fire dragon juice was originally not suitable for brewing life potions, but now … After adding some grapefruit juice, it became an intermediate level life potion material!

Then adding this on top of that, I already have the ingredients needed to concoct four Intermediate Health Potion s. If I were to find another one … Oh, no... Or if I concoct another type of Intermediate Health Potion, would I be able to concoct it? ”Hmm …” If I were to use the Upgrade Box's material to synthesize the juice again, then … What grade of life potion would he get?
