There are many more black water crocodiles in the silt swamp than Jia Yi imagined, even if he uses the magic circle to absorb and transfer most of the radiation, there are still black water crocodiles that are constantly attracted to him, and he doesn't know what he feeds on, whether it is a silt monster or not.

Over time, there are not a few black water crocodiles killed by Jiayi, and the peeled skin can even be used to make a jumpsuit. The skins of the black water crocodiles are so effective at protecting against radiation that he already plans to use them to make a set of radiation suits.

The specially designed magic shield can isolate radiation to a large extent, but it cannot contact the radiation source, and there are many places that need to be exposed to radiation in the back, and it is more reassuring to have a set of radiation protection suits.

In addition to collecting uranium material in the silt swamps, he also went to two other sites to investigate, as well as the place where the convoy had discovered the green uranium mines. Green uranium ore was again discovered not far from the silt swamp. This is an associated mine, mostly copper, with only a small fraction of the green uranium mine, and although the uranium content is higher, the overall reserves are not as good as those of the silt bogs.

What's more, the uranium-235 content in the green uranium mine is lower, and the value is not as good as that of the silt swamp.

Only 235 of uranium's isotopes can produce a natural fission reaction and can release neutrons to produce an avalanche-like chain reaction, while uranium-238 absorbs slow neutrons and will not fission and cannot produce a chain reaction. There is no way to make weapons of mass destruction.

Unless it is allowed to slowly absorb neutrons into plutonium-239, this is another option, which is more laborious.

It took a few days for Jiayi to transform the elemental collection array, protect the periphery, arrange a simple set of locks, hide the elemental collection array, and make an alarm device, when the elements are collected to a certain number, it will take the initiative to send an alarm to remind, as long as Jiayi is still in the underground world, it can be received.

He was also afraid that if he collected too much uranium to reach a critical mass, it would automatically produce a chain reaction, and even if it did not produce a nuclear explosion, it would be extremely wasteful.

Later, I realized that I was thinking too much, the accuracy of the element collection circle was not particularly high, and it was impossible to distinguish the isotopes, uranium-235 and 238 were mixed together, and the neutrons were absorbed by 238, which could not produce enough fission reactions.

After disposing of the uranium ore here, Kaichi returned to Sleepless City, and this trip out, more than half a month has passed, but Isya and their caravan still haven't set off yet. The atmosphere of hustle and bustle in the city became more and more intense, and the convoys of goods carrying large truckloads of goods concentrated in the warehouses outside the city.

In addition to the big chambers of commerce in the city, some small merchants also seized the time to transport goods over, most of which were sold directly to the big caravans, and some of them followed along. This is the time of year when the price of goods is at its highest, and some goods that are not selling well can be sold at the right price.

Dire's market is much larger, and it's a commercial center, and its cargo throughput capacity is far beyond that of a remote town like Nightless.

Not long after Kaichi returned to the city and opened the door of the shop, soon the Minotaur Eun ran in in a hurry, and before he could speak, Owo also ran in with a close-fitting leather armor.

Enti glanced at Owo, ignored her, and hurriedly said to Jiayi, "Master, I heard that you have powerful alchemy props here, I wonder if there are any more?"

Ovo walked up to Jiayi and stared at Enti in surprise, and asked in an unkind tone, "Big man, you're also here to buy alchemy bombs?"

Enti looked at Owo vigilantly, Owo was very well nourished during this time, his figure gradually plumped, and his leather armor was bulging.

As a regular customer of Jiayi's shop, Enyi knew that Owo, although she was not the sturdy type that the Minotaur loved, he knew that Owo's type was the most popular among other humanoid races, and the other party was obviously more familiar with Jiayi, thinking of his mission here, he couldn't help but regard the other party as his biggest opponent.

"You're all here to buy alchemy bombs?" Jia Yi was a little surprised, he didn't sell alchemy bombs publicly, why did all of a sudden both of them come to buy this.

"Yes. Enyi spoke before Ovo and explained, "A few days ago, the station outside the city was almost attacked by a mutated chameleon, and the garrison Far Wanderer Escort used a powerful magic item to blow up the python in one fell swoop, although the other party didn't say it explicitly, but we knew through a special channel that it was provided by you, the master, so we wanted to buy some." We brought with us a list of all the materials for our squad, and whatever you need, we will do our best to meet them. ”

As he spoke, he took out a piece of parchment, put it on the table, and handed it to Jiayi, waiting for Jiayi's reply a little nervously.

"Isya and their secrecy measures are also too poor, how did they leak the news so easily, and let me buy another batch of alchemy bombs, if you hadn't been out for a while, I'm afraid that wouldn't have known about it in the city's adventure group. Owo said and glared at Eun with dissatisfaction.

Eun Yi ignored Owo's dissatisfaction, in fact, they only learned that the Far Traveler had purchased some powerful alchemy props through special channels, but Eun Yi happened to know the weapon used by Eun Yi - the weapon made by Jia Yi had been hanging on the wall behind the counter in the store, and Eun Yi had carefully observed each one.

He wanted to buy it, but the price was too expensive and he couldn't bear it.

Coupled with the magic props that suddenly appeared in the city, it reminded Eun Yi of Jiayi's shop. If it was a work from another shop in the city, it would not have been possible for almost no one to know about it.

He actually came today with the mentality of testing points, but before Jia Yi could speak, Owo had already given a positive answer.

Jia Yi reached out and took the list handed over by Enyi, and checked it a little, the materials in it were nothing special, most of them were minions and fur on the demonic beasts, or mineral medicinal materials, which were far less abundant than the Isya Traveler Escort.

He asked, "How is Enzos doing now, can he control himself?"

Enyi hurriedly replied: "He asked me to say hello on his behalf, he said that he hasn't really learned what you taught, but the situation is much better, at least he won't be unable to control himself because of a little stimulation." ”

"It's good to have progress. He looked back at Owo, "You're here to buy the alchemy bomb too?"

"Yes, your bomb is so easy to use, as long as it is used well, even the Earth Knight will be seriously injured, Isya feels that she has bought too little, and wants to buy some more. ”

The journey to Dire is long and dangerous, and if you can reduce the loss of people with alchemy bombs, even if it is a little more expensive, you can find the Chamber of Commerce to share the burden. It's not convenient to replenish people along the way, it's okay for short distances, but not too many people want to do it for long distances.

Nti also said: "A few days ago, there was a rock python attacking the station outside the city, and the city lord felt that the neighborhood was not safe, and when the chamber of commerce left, it would take a large number of guards with it, and the defense would be even more empty, so I was ready to organize a big sweep when there were enough people now, and completely clean up the surroundings of the Nightless City to remove hidden dangers." ”

The order of the City Lord's Mansion is mandatory, and each adventure team must make a move, although the reward is okay, but the danger is not small, although Enzos's strength has increased greatly, he can't shoot at will, relatively speaking, the regular strength of their adventure team has suffered a big loss.

Only then was he overjoyed after discovering the alchemy bomb used by the Traveler Guard, and hurriedly came over to buy some strength to enrich himself.

The other adventurers just didn't know where the Alchemy Bomb of the Far Wanderer Guardian came from, and if they did, they would definitely come over and find a way to buy two as a last resort.
