The material exchanger led the iron horse and turned his head to leave, but Qin Guan thought of one more thing.

"That...... Please wait. ”

"What do you want to ask?" The material exchanger's beard moved up twice, as if smiling.

Qin Guan: "Since you can talk to me and have "wisdom", if I encounter knowledge that I don't understand in the process of cultivation, can I ask you?" ”

"I don't know, your question is beyond my authority, and it is beyond the authority of the existence of this space world, I am only responsible for the exchange of materials."

Qin Guan: "Okay. ”

But the money changer suddenly said, "Your yard is very barren, you should plant some plants, and you should hire someone to dig a deep well." I'm a traveling merchant in this area, and I'll be there whenever you need it. If you want to open up the wasteland, you can let me know and I can hire workers for you. ”

"Cultivating plants? In this desert? "Don't think about it for the time being, I don't have that mind.

Qin Guan just wanted to try the quenching potion at this time.

The Supplies Exchanger continues to talk to himself, as if a speech bubble would pop up above the NPC in the game, automatically explaining:

"After unlocking the {Caolu} interface in the [Points] catalog, you can use your points to transform the environment of this world, or you can hire 'workers' from me."

Qin Guan: "Okay, thank you, I'll talk about it later." ”

The money changer led the horse away.

Qin Guan has been standing outside the door, looking at the back of a man and a horse, he is not to see this NPC, but to see where he came from and where he will go.

I saw that the material exchanger walked away in one direction very casually, and when he walked about two hundred meters away, he suddenly disappeared out of thin air.

Qin Guan was not surprised at all.

I see.

He turned around and went back to the grass house, ready to concentrate on his cultivation.

This time, knowing that there was another NPC in this world, or most likely more than one NPC, Qin Guan subconsciously closed the fence gate of the courtyard and the wooden door of the grass house.

Otherwise, there will be a sense of uneasiness in being seen.

It's not insecurity, it's uneasiness.

……

The cottage was empty, except for an antique table under the window on the left, and a straw cushion beside it.

Other than that, there is no furniture, only pure wooden flooring.

However, Qin Guan felt that this floor was quite comfortable to lie on, and after three years of hard life, he was now very comfortable with what he encountered, and he was not picky at all.

He put all the potions he was holding on the floor lightly, 1 bottle of light blue quenching elixir, 1 bottle of misty white concentrated element particle liquid, and an additional bottle of concentrated element particle liquid.

There is also a metallic box, which is a level 0 potion set.

When I opened the box, there were 3 small transparent bottles inside, all of which were light blue elixirs, almost the same color and texture as ordinary quenching elixirs.

On the bottle, there is a small label of "one stomach, two lungs, and three hearts".

On the inside of the lid, a short instruction manual is inserted.

"Each bottle of medicine is 150 ml, and the excess is provided by 50%, and the effect will fluctuate according to the difference in individual absorption efficiency and physique."

"Please take a small amount first, a total of three to five doses, quenching the stomach, lungs, and heart three to five times, and wait for 100% quenching to complete, there may be leftovers of the medicine, and you don't need to take it all."

"The formula of each bottle of this box of potions is slightly different, please do not mix."

"The three bottles of potions in this box are slightly different from the formulas of ordinary quenching potions, please do not use them in lieu of each other."

Qin Guan read it carefully.

It feels very rigorous and scientific.

With two books of knowledge and a potion, Qin Guan began his first "cultivation".

To be honest, the first time I came into contact with the new knowledge and potions from an alien unknown civilization, I was still quite apprehensive.

But Qin Guan has a heart, no matter what, try to talk about it.

The current life is already quite bad, even if he is admitted to the military and military university, he is just a mixed one who is well fed, and he doesn't know when he will start a full-scale counterattack, he doesn't know when the human race will win, and he doesn't know if he still has the life to return to the earth alive.

Therefore, no matter how this potion reacts when it is drunk, the result will not be worse than it is now.

Life and death are downplayed.

It's just ~~, before drinking the potion, Qin Guan became proficient in that set of auxiliary actions several times.

Then he unscrewed the No. 1 potion bottle, poured a cap full of about 30 ml, looked at the pale blue liquid in his hand, craned his neck, and swallowed it all in one gulp.

After that, smash it, smash it, it seems to be tasteless?

Soon, the stomach churned violently, and there was a strong burning and flatulent sensation.

It hurts, it hurts, it hurts!

Like a furnace fire burning flames in the stomach, there is also a large boiler in the fire, spewing high-temperature bubbles outward.

He instantly understood what that self-anestheticing agent was for!

Qin Guan knelt down in pain, his whole person was like a big shrimp bowing on his back, the green tendons on his forehead were bulging, and his hands were tightly covering his stomach, but he couldn't alleviate this burning pain in the slightest.

It's a pity that ~ I can't afford to exchange it ~ that expensive anesthetic, even if I can change it, I can't bear to ...... How many tasks do you have to brush~ to brush up on 3000 points......

You have to fight 300 horn soldiers!

With that strength, it is better to endure the pain, maybe you will get used to the pain as soon as it hurts, and your tolerance can be improved......

Finally breathing a sigh of relief, he gritted his teeth and endured the burning pain, straightened up, stood up, and tried to suppress the urge to hiccup, and began to do the quenching auxiliary exercises.

Gradually, the gas and burning sensation began to lessen.

It works!

Qin Guan breathed a sigh of relief, and continued to repeat the auxiliary action, doing it more than thirty times, and about two hours passed, and the feeling of churning in his stomach finally slowly subsided.

The first gastric quenching is done.

"Hoo ......"

Qin Guan exhaled profusely in sweat, supported the floor with one hand, sat down slowly, and then, flattening his limbs, in an extremely relaxed posture, spread himself flat on the floor.

Who said that only cats are liquid, and it is the same when people are extremely tired......

It's really damn bad, I don't know what the situation will be in the future.

Afraid? Qin Guan clenched his fists lightly, cheering himself up, he had survived the first tempering, there was nothing to be afraid of!

Next is the rest time.

Qin Guan was lying on the floor, sweating profusely, counting his breath, and soon~ fell asleep.

This sleep, I slept for three hours.

After waking up, Qin Guan felt extremely hungry, the kind of hunger that he could swallow half a cow alive!

He dragged his legs and walked to the shopping cart in the corner, thinking that fortunately he had carried forward the spirit of stockpiling food before, and carried five carts of food and drinks very wisely, otherwise he would be hungry and tired now, and where would he have the energy to go to the map three years ago to find food.

Oh, that's probably what that nutrient solution was used for.

Fortunately, I took the food myself, so I saved 30 points casually.

Qin Guan sat directly next to the shopping cart, eating as he pleased, whether it was meat staple food or milk drinks, he opened his appetite and ate a lot of food, eating enough of his usual five or six meals, only then did he stop, and he felt that his energy had recovered a lot.

At the same time, there is a vague feeling of freshness and wonder in the stomach, compared with the past, the stomach wall muscles seem to have become stronger, the ability to contract and move is stronger than before, the digestive function is strengthened, and the nerve endings in the stomach are more developed and sensitive!
