However, let’s wait until all five people over there have met before discussing the matter.

Now it seems that Wang Lei is the only one there.

Xu Xin looked at the time, it was nine o'clock in the evening, it was too early to go to bed.

So he came to the alchemy room and prepared to continue his great work of alchemy.

At present, there is no way to get past the other five people. If they cannot get past, they will not be able to activate the coordinates. Therefore, the creation of the coordinates can be put on hold for a while.

His alchemy room has already consumed a full 380% of his increase points, and the success rate is already very high. It cannot be left to gather dust. He is ready to start making alchemy potions that can enhance the personal strength of survivors.

Now, he still has five copies of all-purpose alchemy materials on hand, and he can just make a few copies first to test the effect.

Currently, he can only refine blue-level potions. As mentioned before, he can refine blue-level fruits into potions to permanently increase the abilities of survivors.

However, he has used strength potions before and knows the extent of the increase in strength. The increased strength is much weaker than the temporary increase in strength after eating the apple (blue), but the advantage is that it is a permanent ability and it is his own ability.

And can be accumulated.

Currently, there are only four types of alchemical potions that can be made in the list of alchemical synthesis stations.

[Strength potion (blue): a potion that can permanently increase strength in a small way, requires apples (blue)*10, universal alchemy material (blue)*1]

[Psychic potion (blue): a potion that can permanently increase mental power in a small way, requires oranges (blue)*10, universal alchemy material (blue)*1]

[Stamina Potion (Blue): A potion that can slightly and permanently increase the speed of physical recovery. It requires Apricot (Blue)*10 and Universal Alchemy Material (Blue)*1]

[Vision potion (blue): a potion that can permanently improve vision in a small way, requires red berries·large (blue)*10, universal alchemy material (blue)*1]

Xu Xin noticed the first three types last time, but the fourth one surprised him a little.

"Improve eyesight?" Xu Xin's eyes lit up.

Last time, he only took a general look and did not read the introduction of this potion carefully. He thought it was a potion that could slightly improve night vision.

Does it improve eyesight... Blue-level red berries themselves have no ability to improve eyesight. Eating blue-level red berries only makes the night as clear as day. Things that should be seen clearly are still unclear.

Just like a short-sighted person, even if he gains night vision, his vision is still blurry.

But improving eyesight seems to be different.

Is this improvement in eyesight just like his random increase last time, which allowed him to see more clearly, both near details and distant situations?

Xu Xin thought of Qi Xuefei.

She is myopic. They had discussed how to treat myopia before, but they didn't expect that the solution was in their own hands.

Not bad, good stuff.

He looked at the other potions.

Well... there is no need for the strength potion now. He has used a bottle of strength potion before, and the improvement is not very big. And his strength is already strong enough now. With the halberd and explosive crossbow bolt in hand, the strength is actually enough.

That's fine, there's no need to be so strong.

Just like today, he received a strong increase in strength, but apart from crushing Ma Hongyu's hand, it didn't seem to have any good effect, so the strength potion should be used later.

Make one of the other three potions, mental potion, physical potion and vision potion, and try the effect!

There are plenty of oranges (blue), apricots (blue), and large red berries (blue) in the backpack, enough to make potions.

Xu Xin immediately controlled the alchemy synthesis platform and used the raw materials he had to make all three bottles of alchemy potions at once.

Looking at the three different colors of "juice" produced on the synthesis table, and smelling the fragrant and rich fruity aroma floating in the air, Xu Xin couldn't help but swallow.

After all, this is juice concentrated from ten fruits!

He picked up the vision potion and drank it in one gulp.

The rich taste of red berries exploded in his mouth, and at the same time, there was also a faint taste of metallic rust. The last time he drank a bottle of strength potion, it also had this strange taste.

...I'm a little afraid of heavy metal poisoning.

A coolness flowed into the abdomen along the esophagus, then flowed throughout the body, and finally stopped in Xu Xin's eyes.

The refreshing coolness made his tired eyes instantly clear, and his vision seemed to have become clearer.

Xu Xin was not short-sighted, and he could see everything in the house clearly. But this bottle of potion gave him the feeling that it made the world a little bit clearer. Although it was not obvious, it did.

He walked to the window and looked out.

It's night now, and there are stars in the sky. It's not too dark outside, but it's still not as dark as daytime.

He did not eat red berries, so he did not gain complete night vision, but at this time, he felt that he could see the jungle under the stars more clearly than he had before without eating red berries.

"...In my normal state, my night vision ability has also been enhanced?" Xu Xin touched his chin.

The effects should be stackable. If he uses a few more bottles of vision potion, he should be able to obtain true night vision that makes the night look like daylight.

"Yes, I can make this night vision permanent and become an ability that truly belongs to me." Xu Xin nodded.

A permanent ability is much more reassuring than an ability that can only be obtained by taking medicine. Even if he has more red berries in his hand than he can finish.

He drank the [Psycho Potion] and the [Physical Strength Potion] again. A chill lingered in his brain and body. After using three bottles of potion in succession, Xu Xin felt a chill in his body.

The chill gradually swept through the whole body, making Xu Xin shiver and let out a breath of cold air.

"...What's going on? Can't this medicine be taken continuously?"

The temperature in the room was more than 20 degrees, and he was wearing purple scale armor. Under normal circumstances, it was impossible for him to feel cold. This must be a side effect of the medicine.

He didn't know whether it was because of the coldness all over his body or because he had taken psychotropic drugs. His brain was now unusually awake, but his body was extremely cold and uncomfortable. His awake brain could more clearly feel the bone-deep coldness on his body.

"Huh..." Xu Xin felt that her breath was cold.

This alchemical potion cannot be used continuously!

Not caring about feeling the changes in her mental and physical strength, Xu Xin hurriedly came to the fireplace to warm herself up.

Silver King and Mimi were crouching in front of the fireplace to warm themselves up. Xu Xin squeezed directly between the two beasts, feeling the warmth of the fireplace flames and Silver King Mimi's warm body temperature at the same time.

"Ouch?"

"……Meow!"

After Xu Xin squeezed in, Yinwang and Mimi didn't react at first, and then suddenly jumped up and away from him.

They could all feel the coldness radiating from Xu Xin's body. This feeling made them very uncomfortable, so they stayed away from Xu Xin.

Xu Xin immediately leaned against the fireplace again, but it did not relieve the chill in his body.

He felt like he was like a refrigerator with the door closed on a hot day. No matter how hot it was outside, his body was still very cold.

Misstep.

In the introduction of the medicine, there is no mention that it cannot be taken continuously...

This should be his own problem.

His current physique may not be able to withstand taking the medicine three times in a row.

Xu Xin breathed in the air, her body trembling slightly due to the cold, and she regretted her recklessness.

Fortunately, this cold feeling did not continue to deepen, nor did it last for too long.

After about a quarter of an hour, the bone-chilling chill suddenly receded like a tide.

The body was immediately penetrated by the warmth of the furnace, and Xu Xin felt comfortable all over.

"Huh..." He breathed a sigh of relief and stood up.

It's finally over. I can no longer take medicine continuously.

However... the consequences of this are not very serious. You can experiment a little next time and see how long the interval is before you can use the second bottle of medicine.

Why not let Lou Feier be the test subject?

...Forget it, she is one of our own after all. Moreover, she is now a mutated creature, which is quite different from ordinary survivors. There is no practical significance in using her as a potion experiment. After all, the reaction is likely to be different.

However, she can be used to conduct experiments related to mutant organisms. After all, she can communicate accurately and describe her feelings clearly, which allows Xu Xin to better understand the situation of the experimental subjects.

Xu Xin suddenly felt that her thoughts were a bit like a villain.

…Let’s wait until there is a need later.

Standing up, Xu Xin felt the changes in mental and physical strength, but there was no obvious feeling.

Because he had withstood the cold for more than ten minutes, his mental and physical strength was not even as good as before. His mind and body had become a little tired.

However, these two medicines increase the upper limit of mental and physical strength. The upper limit is very vague and he can't feel it.

Forget it, let's leave it at that for now. I hope the two medicines he took later didn't lose their effectiveness because of his recklessness.

Xu Xin returned to the alchemy room, made another bottle of vision potion, and then initiated a transaction with Qi Xuefei.

Qi Xuefei was probably still researching some medicine. It took a while before she agreed to the deal and sent him a voice call.

"This is one of your alchemy potions, vision potion, can it cure my myopia?" Qi Xuefei's voice was filled with surprise. She didn't expect Xu Xin to have this type of potion.

In this world, she suffered a lot because of myopia.

Not only Ma Hongyu's time, but also any previous activities, such as jungle hunting activities, dungeon exploration activities, etc. Her myopia caused a lot of trouble to her. After all, you have to get close to see things clearly. It is really

It affects exploration and hunting too much.
