Hearing Luo Hong's words, Li Chenzhou was also stunned, then nodded for him to continue.

"There's no problem with the mutated crystal nucleus, but we haven't encountered the strengthened zombies you mentioned yet, and I don't know when you'll be back. So, if I've obtained the mutated crystal nucleus by the time you return, I can naturally use it to pay off the debt. But if I haven't, I can only continue to owe you!"

Luo Hong looked at Li Chenzhou and said,

"Also, mutated crystal nuclei can make people stronger, and your potion also makes people stronger, so… what's the difference between the two? You want me to return two mutated crystal nuclei; is that extra one considered interest, or is it to compensate for the difference between the two?"

After asking the last question, Luo Hong quickly added,

"Don't get me wrong, I'm completely fine even if it's interest. I said, you can even take over that base at any time, although it hasn't been built yet. I just want to know the difference between the two, which one is better. That way, after the people in my base obtain mutated crystal nuclei, I'll know what to choose!"

Luo Hong's words surprised Li Chenzhou. He didn't expect that just taking out an injection would make Luo Hong think so much. And these were precisely the foundations Li Chenzhou planned to use as a businessman—to let every base, every survivor, know the benefits of evolution potions!

Because the business he was doing would definitely lose money at the beginning, since an evolution potion cost 500 Slaughter Points, while the lowest-level mutated crystal nucleus could only be exchanged for 100 Slaughter Points in the shop, a difference of 400 Slaughter Points.

But if he wanted people to exchange an evolution potion for five mutated crystal nuclei, probably no one would agree, because other people didn't have a system and couldn't directly see the information of the evolution potion. They could only know the benefits of the potion after using it, and there also needed to be a comparison with strengthened individuals who had used crystal nuclei!

So, in the early stages, Li Chenzhou's exchange was definitely a loss, because he set two types of prices. One was a trial exchange, a one-to-one ratio, that is, one crystal nucleus for one evolution potion. This was for each base to experiment, to let them know the benefits of the evolution potion, just like a product sample.

And the other type was a normal exchange, that is, the price when they knew the benefits of the evolution potion and came to Li Chenzhou to exchange for evolution potions again. This price was two to one, that is, two crystal nuclei for one potion!

But even with a normal exchange, two level-one crystal nuclei were only 200 Slaughter Points, and Li Chenzhou would still lose 300. To make a profit, he would have to reach at least level-three crystal nuclei!

Moreover, the exchange of evolution potions had a restriction: it had to be the same level, and it wasn't allowed to be taken away. Whoever exchanged it had to inject it immediately. This was a restriction Li Chenzhou made to ensure his own profits.

Same-level exchange meant that if the other party was a level-X strengthened individual, they needed to use level-X mutated crystal nuclei to exchange with Li Chenzhou, because the evolution potion had no level, only the failure rate increased with level.

So, if there were no restrictions, then everyone would use level-one mutated crystal nuclei to exchange with Li Chenzhou, and he would never be able to profit.

The main reason Li Chenzhou wanted to be a merchant was to earn Slaughter Points. Even knowing about the existence of the Devourers and wanting to improve human strength as soon as possible, he still needed to benefit himself.

So, the above was the transaction plan Li Chenzhou came up with. If someone improved to level four, they would need to use two level-four crystal nuclei to exchange for an evolution potion from him, and if they failed, they would have to get two more level-four crystal nuclei.

At that time, Li Chenzhou would begin to profit greatly. In the early stages, he still had to make the name of the evolution potion known first. In addition, Li Chenzhou would also open up the exchange of other items in the mall, such as treatment potions and various food weapons.

This was a true merchant: he had everything. As long as you had crystal nuclei, he had something to sell you. Moreover, Li Chenzhou planned to sell other commodities at double the price. For example, if a set of combat suits cost 100 Slaughter Points in the mall, then Li Chenzhou would sell it for two level-one crystal nuclei or one level-two crystal nucleus!

The price might not be cheap, but this thing was a monopoly, so Li Chenzhou wasn't worried about anyone competing with him for business at all. Moreover, putting other items on the shelves could also consume the extra crystal nuclei in other people's hands!

This was Li Chenzhou's current plan. Of course, in this world, to be such a mobile merchant with everything, he needed strong self-protection capabilities. Therefore, Li Chenzhou had to ensure that his level was always at the forefront. In addition, the space chariot also needed to be settled as soon as possible!

Therefore, after hearing Luo Hong's words, Li Chenzhou hesitated slightly, then took out a set of combat suits and said to Luo Hong,

"First of all, the effect of this potion is much stronger than crystal nuclei. It can allow you to obtain abilities that you might never be able to get from using crystal nuclei. To be honest, the value of this potion is at least more than five crystal nuclei!

"However, because not many people have used this potion yet, I need some people who have used it to prove its power, and these people will naturally get discounts! You are the first!

"The future price of this thing will be two crystal nuclei for one, which is the price I'm asking you for. But because you are among the first batch of users, consider this a discount for you. Wear it, and you can basically ignore the attacks of ordinary zombies!"

"You… you really are a transmigrator?"

Seeing a set of combat suits suddenly appear in Li Chenzhou's hand, Luo Hong was stunned and blurted out.

"No! I'm a businessman! A businessman with a lot of inventory!"

Li Chenzhou said softly, then sent the potion to Luo Hong:

"Use it first!"

"Right here?"

Luo Hong took the potion!

"Yes! Right here!"

Li Chenzhou nodded. This was only the second potion he had exchanged so far. He still wanted to see how long it took for others to use it, as well as the effects after use.

Hearing Li Chenzhou's words, Luo Hong no longer hesitated and immediately took the potion, stabbing it into his arm…

Afterwards, Luo Hong began to turn red and his eyes became illusory, as if he had been hypnotized. Then, his body began to shake.

The whole process lasted less than three minutes, and Luo Hong gradually returned to normal, and his eyes finally ceased to be illusory.

"How is it! What ability did you get?"

Seeing Luo Hong come back to his senses, Li Chenzhou quickly asked. Luo Hong wasn't his follower, so he couldn't know his current combat power changes…
