Time passed quickly, and the three days passed quickly, and the control experiment of the hair growth agent had a rough result.

Qin Haiyan's worries are not unreasonable, there are some hair growth elixirs in it, which are useless for humans.

And a few individual medicines, the effect is very weak, almost negligible, can play a small role, not so much hair growth, but hair care, hair loss, Chen Nai feels that this can be used as a care product in the future.

At present, the effect is good, and there are only a few models, but as for whether there are side effects, this is a bit difficult to say.

After all, it has only been an experiment for three days, and it will take at least three months of experimentation and several courses of treatment to determine whether there are any side effects.

But Chen Naike can't wait that long, after all, he is now a big family, not only has an underground factory waiting to open, but also needs to collect a lot of raw materials to get it running.

Moreover, nearly 3,000 people have to feed, 3,000 mouths are waiting to be fed, and the food consumed every day, firewood, rice, oil, salt, sauce, vinegar, tea, these are all a lot of consumption.

The grain that was originally stored was only enough for about 300 people of the Berserker tribe to last for about a month and a half.

But now there are more forest trolls and half-orcs, and their appetites are also not small, so the consumption has increased dramatically.

Although it is possible to let them hunt and pick wild fruits and vegetables on their own to reduce their consumption, this is not a long-term solution after all.

Cultivating land and growing food is the top priority that must be done at the moment.

It's just that the wizard and patriarch of the forest trolls, because of their injuries, have not yet recovered, and there are no seeds at the moment, so they have to be put on hold for the time being.

The only thing that is good is that the berserker tribe has grown their own food, which is almost ready to be harvested.

The scouts sent by the night only probed the information of the place of residence, and did not damage it.

Although the production capacity of that batch of grain is not very high due to the previous drought and the lack of soil fertility, it can still be maintained for a period of time after harvesting, which is the only good news at the moment.

Making money and maintaining expenses is the most important thing right now.

Chen Nai carefully selected three more effective and safe and harmless medicines as the main products, and planned to promote them.

So who is going to market this product, that's the first question?

Emma, Qin Haiyan and Burton, and others have already been to Hongdu City before, and now the limelight is estimated to have not passed, which is considered a sensitive period, and there is a risk of exposure if they go again.

Chen Nai thought about it, Carter is a good candidate, firstly, he has never shown up, and secondly, his profession is a pharmacist, and he sells his own products, there is nothing wrong with it!

As soon as he heard that he was going to sell his own hair growth potion, Carter shook his head again and again and said, "I'm just a pharmacist, and I'm not a businessman, so I'm afraid it's not okay for me to sell and sell." ”

"Don't worry, this is just for you to come forward, you just follow what I told you, and you don't need to worry about the rest at all."

Chen Nai already had an idea in his heart, Carter just came forward to attract the attention of others, and he was not the one who really got the idea.

He doesn't know how to do business, but others do.

"I'll let Qin Haiyan and Burton, as well as Charlie's knights, escort you."

When Charlie and the others on the side heard this, they suddenly had a feeling of tears, how to say, as a knight, he finally got back to his job, instead of being a logistics staff like the Firehead Army.

"No problem, Master Cat!"

Burton immediately agreed, but Qin Haiyan frowned slightly.

"My current situation is very sensitive, and you still want me to go to Hongdu City to show my face, isn't this asking for trouble?"

"Don't worry, how could I ignore this question and make such a low-level mistake, come on, look at this set of clothes I have prepared."

Chen Nai took out a black and white fashion suit, and at first glance, this was a white dress, plus some black spots, nothing strange.

But Qin Haiyan took this set of clothes and gestured on his body, and his face became a little strange.

"What's this outfit called?"

"Uh...... Spotted outfit! ”

"The look on your face, and the way you paused for a second before answering my question, shows that you're lying."

"Well, it's called a cow."

"Change."

"I think it's good, it's pretty good, what's the problem?"

Qin Haiyan didn't answer this question, just glanced down at his chest, and at that moment Chen Nai understood that the problem was there.

The cow costume is indeed not suitable for the current Qin Haiyan, after all, she is not yet seventeen years old, she is still developing, and now she is only at the level of B, and she really can't support the broad mind of the cow suit.

Understandable, understandable!

"Then put on this set, Lin Wei's skirt suit, which is used by the rangers, but it is a little not very good-looking."

Lin Wei's skirt is for rangers, the whole is brown, not bright and eye-catching, compared to other fashion suits, this one is too low-key.

"It's good, it's low-key, give me another bow and a quiver around my waist, and I can pretend to be a ranger."

"Then it's decided, this is the human skin mask I forged for you and Burton, its biggest use is to disguise yourself, after wearing it, your facial features and hair color can be adjusted, you can try it."

The function of this human skin mask is, to put it bluntly, a face-pinching function, and after wearing it, it can be fine-tuned on the basis of the original appearance.

Change the hair color, eye pupils, pull double eyelids, increase the bridge of the nose, and then have thick lips, so that you will suddenly become unrecognizable when your mother comes.

Watching Qin Haiyan pinching her face and pinching it was fun, Emma also threw herself into the game of pinching her face, and after playing for a while, Emma said to Chen Nai.

"Master Cat, you can get me one."

"My Emma is so beautiful and cute, what do you want this thing for."

"It's fun!"

"Then I'll play with you in two days, I can only build these two with the materials I have."

"Oh, don't forget that, the cat."

"Marketing plan, as well as advertising words and other things, I told Qin Haiyan, when you listen to Qin Haiyan's instructions, just do things."

"Understood."

"Next, whether we eat fragrant and spicy food, or eat bran throat vegetables, depends on whether your sales pitch can be successful."

"I'll try my best!"

Although Qin Haiyan grew up in a trading city, he naturally knows a lot of things since he was a child, but he understands what effect he can get in practice, and he can only look at the results.
