After listening to the description of the goblin boss, Jiang Feng could say very responsibly that it was not because of any curse that caused the death of that unlucky guy.

Tooth loss, hair loss, and the radioactive stone made it clear that the mercenary was the result of a prolonged violation. Exposure to radiation can lead to radiation sickness. Not to mention the medical level of this world, even the world of Yira is helpless against this disease.

"Naturally occurring radioactive minerals are limited by cut-off grades and cannot produce such a large amount of radioactivity, and only artificially purified radioactive materials can produce fatal gamma rays."

"Could it be that someone has built a nuclear facility there?" Glancing at the medieval-style buildings on both sides of the street, Jiang Feng, who was amused by the thoughts that suddenly popped up in his head, shook his head with a smile, "How is it possible." ”

"It seems that you will only know what is going on there until you have been there."

Because he was thinking about something, Jiang Feng, who was walking on the street, was a little distracted for a while, and his shoulder collided with the oncoming kobold mercenary.

The kobold mercenary who had been knocked on the shoulder glanced back at Jiang Feng, his dark green pupils were like jackal's eyes.

However, to Jiang Feng's surprise, the dog-headed mercenary in front of him, who looked fierce and vicious, unexpectedly did not trouble him, but said sorry in the broken Chinese language of King Rick, and walked away from his companions in a low-key manner.

Glancing at the group of mercenaries, Jiang Feng's eyebrows furrowed slightly.

The backs of those people always made him feel that something was wrong, but he couldn't say what was wrong.

Shaking his head and deciding not to think about these things that had nothing to do with him, Jiang Feng walked in the direction of the city gate.

……

Before the sun went down completely, Jiang Feng left Boulder City.

When he passed through the city gates, the guards dodged from him as if they were hiding from the plague god, not to mention making trouble for him, for fear that he would take a second look at him and become a second Bancheno.

Returning to the hotel outside the city, the innkeeper greeted him with a letter in his hand.

"My lord, I was asked to pass this letter on to you."

After taking the letter and opening it, he glanced at what was written on the parchment, and Jiang Feng casually stuffed it into his pocket.

The ruler of the city reacted surprisingly quickly, and in less than an hour, the apology had already been delivered to him. The name of the check-off office is Salos Covifort, who is supposed to be the mayor of the city.

In the letter, the mayor swore to Jiang Feng that he would severely punish the captain of the city gate guard named Bancheno.

However, Jiang Feng didn't take that little role to heart at all, if it wasn't for this letter, he would have almost forgotten that little episode.

"Help me get some food that I can take with me on the road, wheat crackers and jerky, and it will take about three days for two people."

After speaking, Jiang Feng threw a few silver coins into the hands of the boss.

"Okay!"

With the silver coin in hand, the boss happily went to the kitchen.

Turning around and going upstairs, at the door of the room, Jiang Feng met Fielding, who had just returned.

Seeing Jiang Feng, Fielding said respectfully.

"My lord, I've bought all the things you asked me to buy."

"Good job, where's the thing?" Jiang Feng asked.

"At the stables, of course...... Because there were so many things, I hired two mercenaries there to help us keep an eye on them. After a pause, Fielding asked cautiously, "May I take the liberty of asking?" What are you going to do when you buy so much saltpeter and sulfur? ”

If it's a potion, you won't need that much sulfur at all. As for saltpeter, Fielding couldn't think of any other use for it other than to make herbs and ice.

Jiang Feng didn't explain much about Fielding's confusion, but just smiled mysteriously.

"You'll find out in a few days."

After dinner, Jiang Feng checked Emily's homework and returned to his room.

After closing the door, lighting the candle, and sitting down at the wooden table, he took out the potion refining equipment from the spatial ring.

As early as on the road, he made minor improvements to the recipes recorded in Monkyrie's notes based on the various mana potion recipes he had learned from the Vallan Alchemist Guild, removing some useless and harmful impurities, and concocting a pot of mana potions.

Putting the turbid blue liquid in the crucible into the fractionation flask, Jiang Feng took out a simple thermometer made with mercury and glass and inserted it into the branch nozzle, carefully controlling the temperature of the flame, and finally refined the blue turbid liquid with a full 1L amount into less than 200 ml of clear blue oil.

I saw that there were a large number of impurities and viscous mixtures left in the original fractionation flask.

These were the slag left over from the preparation of potions, as well as the sediment of useless components, because the world's filtration technology could not separate the smaller particles in the liquid, so Jiang Feng applied a simple fractionation method to purify it.

With a sigh of relief, he took the beaker off the end of the branch nozzle, and Jiang Feng shook it slightly in his hand a few times.

I saw that the crystal clear liquid surface was like a flowing blue crystal. With such a high-purity mana potion, I'm afraid that even the wizard continent on another planet won't be able to find a second one. Compared to the original mana potion that needed to be shaken well before drinking, this improved mana potion has more than doubled the recovery effect, and there is no side effect of mental fatigue.

"Brain, scan the liquid in the flask."

【Scanning......】

[After the scan, the analysis results are as follows......]

Rows of analysis results are presented on Jiang Feng's retina. Not only about the pharmacological properties of this bottle of potion, Zhi Brain even simulated the recovery effect of drinking the improved mana potion based on Jiang Feng's own body data, and compared it with the pharmacological properties of the original mana potion based on the data collected from the turbid blue liquid before.

"With my current mana attributes, drinking 20 ml of improved mana potion can probably restore about fifty percent of mana, and repeated drinking will produce resistance for a certain period of time, weakening the mana recovery effect. Combining these factors, the three-pronged mana potion allows me to unleash at least 5 more apprentice-level sorcery! ”

"If you take this thing to the Wizard Continent, you should be able to exchange it for a lot of magic stones from those wizard apprentices."

After sighing for a while, Jiang Feng took out ten empty test tubes from the space ring and carefully filled the liquid in the beaker.

Two tubes of fluorescent potions and one of fire-burning potions were removed from his belt, and three tubes of mana potions were tucked into the empty slots for quick use in combat. In order to prevent accidentally taking the wrong potion and drinking the fluorescent or igniting potion by mistake, Jiang Feng deliberately left marks of different colors on the cork of the test tube.

When all this last night, the moon had risen in mid-air.

"It's not early, so I'll be here today."

Looking at the sky outside the window, thinking that he would have to go out with Leia tomorrow, Jiang Feng put the alchemy equipment on the table into the space ring, washed it briefly with the hot water brought by the innkeeper, and then blew out the candles on the table to end the day.
