Let's suffer a little longer, fellow Blue Star folks.

It is not advisable to get something for free.

Then he looked carefully at the pattern drawn on the paper and found that apart from symmetry, there seemed to be no pattern.

"Do you know what the principle is?" Ah Tui looked at Erwuzai and asked.

"Don't make it."

Erwuzi handed the copper piece to Ah Tui, then thought for a moment and continued:

"Engineer Song said before that this pattern guides the flow of 'qi' within the medium, and this flow conforms to certain laws, ultimately forming the corresponding phenomenon."

"So as long as we grasp the laws governing the operation of the rules, many problems can be solved with Qi formations."

After hearing this, Ah Tui blinked silently.

"Sounds quite scientific?"

"So that's the pattern painted on the barrel of your cannon?"

The idiot nodded: "Yes."

In fact, he knew about the Qi formation a long time ago.

After all, when the cannon was tested before, he saw the patterns inside the barrel flash for a moment, and there was no device in the base of the cannon that could generate propulsion.

Then it could only be that these patterns played a role.

So after Song Lian was brought to the gathering place by [Gugu] and began to repair the Qi gathering cannon, he immediately asked about this question and learned about the existence of the Qi formation.

It was also because of this that he thought of asking Song Lian whether there was a lighting array.

"Ah."

Ah Tui nodded, then took the copper piece and began to continuously output energy into it, watching the copper piece begin to flash.

"It seems that this thing is also a big question."

But fortunately, he is an engineering major and is responsible for the specific application. As long as they solve the problem of energy transmission in the future, the gas lamps in the gathering place will be available.

At that time, they will contract the installation of lighting equipment in the gathering place and make a lot of money.

"whee."

Ah Tui couldn't help but laugh out loud.

After that, the two did not stay in the gathering place for long. In order to avoid any further complications, they immediately took their things and rushed to the construction site outside the gathering place.

There is a temporary factory built by A Tui and others, where subsequent research can be carried out.

However, as soon as he walked out of the east gate, Erwuzai saw Alps walking into the gathering place with a man and a woman.

"Legs, legs."

Erwuzai patted Ah Tui's shoulder, then pointed in the direction of the Alps and said:

"Look over there, who are those two by the Alps? Are these two NPCs in our gathering place?"

Ah Tui paused, then turned his head to take a look, and immediately looked away.

"It seems like he's a traveling merchant coming to the gathering place."

He doesn't care about that.

For him, the most important thing now is to complete the tasks related to lighting equipment. Everything else has nothing to do with him.

The Alps in the distance didn't notice Erwuzai and Atui either.

While chatting, he took Wang Yi and Fang Xin to the mission hall on the east side of the gathering place.

He remembered that if Xia Keyu had nothing to do outside, she would handle matters in the small room next to the hall.

He walked expertly down the hall and knocked gently on the door.

"Please come in."

Sure enough, he was there this time.

Hearing the knock on the door, Xia Keyu put down the plan in her hand. When she looked up, she saw Alps and the other two.

"Sister Keyu, I met a few guests from the west in the valley. They wanted to replenish some supplies at the gathering place and talk to us about cooperation."

As Alps came in, he spoke to Xia Keyu. Seeing Xia Keyu nodded, he turned around and looked at Fang Xin and Wang Yi.

"Let me introduce you two. This is Xia Keyu, the vice-emperor of our gathering place... ahem, the assistant to our leader. She is currently in charge of handling most of the affairs of the gathering place."

Fang Xin also smiled and nodded, then took a step forward, looked at Xia Keyu and said:

"Hello, we are merchants from Yuanfu Town. It's a pleasure to meet you."

Chapter 162 A Trip to Yunhe Town

Far away service town?

Xia Keyu raised her eyebrows, and the look in her eyes when she looked at Fang Xin changed slightly.

She remembered that this town was very close to Yunzhong City, almost like a subsidiary city of Yunzhong City.

And because he participated in the founding of the Yunzhong Chamber of Commerce, he also owns a portion of the shares of the Yunzhong Chamber of Commerce. It is considered one of the richest towns in the northwest region.

What kind of cooperation can they achieve with the gathering place?

But since guests are welcome, she asked Alps to bring two chairs.

"Thank you."

Fang Xin took a chair and sat opposite Xia Keyu, Wang Yi sat half a step behind her, and Alps sat in front of the door and closed the door.

Xia Keyu also took two clean cups from the side, poured a glass of water for each of them, and then asked casually.

"I saw the caravan from the Yunzhong Chamber of Commerce just returned from town a while ago. What good business have you two found?"

"It's just some small business." Fang Xin said with a smile, "It's mainly because there are some places where the caravan's carts are difficult to pass, so we have to do it for them."

"Oh?"

Xia Keyu placed two glasses of water in front of the two of them, then sat back in her seat and looked at Fang Xin again.

"Doesn't the Chamber of Commerce have any partners in Jiaoqiu? Wouldn't it save a lot of effort to let them do it for you?"

"Yes, there are. It's just that some villages over there don't have a good relationship with the town, so we still need to visit each other more often."

Fang Xin picked up the water, answered Xia Keyu's question, and then took a sip.

"Alas, some villages are still a little small." Xia Keyu shook her head slightly. "In this world, if small villages want to survive, they will eventually have to rely on large gathering places."

"The relationship between the two sides has become too strained, and the only ones who are likely to be hurt are small gathering places like us."

"That makes sense." Fang Xin nodded in agreement, then she looked at the scenery outside through the window of the room, then turned back to look at Xia Keyu and said with a smile.

"It seems your gathering place has a good relationship with Yunhe Town. The Yunhe Army has even set up an office here."

"Okay."

Xia Keyu did not deny this. After all, there was such a big office there, it was nonsense to say that the relationship was bad.

"The Yunhe Army has entrusted us with the task of defending this valley. Setting up an office here will also make it easier for us to communicate with them."

Fang Xin nodded as if suddenly understanding something, and her tone rose slightly.

"This place is considered a military stronghold. Would it be a bit taboo for businessmen like us to come here?"

"That's not the case." Xia Keyu said with a smile, "You are the first group of merchants to come to our gathering place."

"However, we may set up a base on the road outside the valley in the future. We will use that base as the center and conduct some transactions with the surrounding gathering places."

"That's a good idea." Fang Xin nodded approvingly.

"Otherwise, with so many merchants coming and going, it will eventually have an impact on your defense."

"..."

Listening to Fang Xin and Xia Keyu's words, Alps took a small stool and sat alone by the door, falling into deep thought.

Didn’t we agree to come here to discuss cooperation?

Why are we chatting here now?

Shouldn't he be here?

But before he could think about it, Fang Xin took the initiative to bring up topics related to cooperation.

"We just visited the morning market in the gathering place and found that you are selling synthetic potions, which are considered rare resources in our chamber of commerce." Fang Xin said with a smile.

Although she tried it when she just returned, she found that the effectiveness of other potions except the mana recovery potion was much worse than those sold by the Chamber of Commerce to the Mercenary Association.

But after all, there are too few forces researching these medicines, and the supply is limited. Now that she has encountered it, she definitely cannot let it go.

Xia Keyu nodded secretly.

These people really came here because of the potions developed by the players.

"We're just doing a small business. Compared to your Chamber of Commerce, our output and effectiveness are far behind." She smiled and shook her head.

"Even a small fight is impressive." Fang Xin continued, "After all, only the government in Yunhe Town has some research on potions, and they don't sell them to the public."

"So, if you want to sell these medicines to other villages in Yunhe Town, or to other towns and villages, you can also contact our Yunzhong Chamber of Commerce."

Having said that, Fang Xin also took out a metal badge and placed it on the table.

"There's a shop of our Yunzhong Chamber of Commerce in Yunhe Town. If you want to cooperate, just give this to them."

"If you're only selling within Yunhe Town, we'll only charge a small handling fee. But if you're trading across towns, the handling fee might be slightly higher."

"Of course, if you have items that are difficult to handle, you can give them to us. We have ways to find buyers for them."

Having said that, Fang Xin also winked at Xia Keyu.

Something inconvenient to handle?

The smile on Xia Keyu's face didn't change at all.

It turns out that these people not only like the potions made by players, but also the defective ones.

No wonder they care so much about Yun and the army in our gathering place.

"That's great. We'll send someone to the town to talk as soon as possible." She nodded slightly.

After that, Fang Xin and Wang Yi didn't stay in the room for too long. After exchanging a few simple greetings with Xia Keyu, Fang Xin suggested buying some supplies.

After learning the quantity of supplies, Xia Keyu decided to give them as gifts.

Alps, who had been waiting for a long time, finally had work to do.

He immediately stood up, opened the door, and took Fang Xin and Wang Yi to the warehouse.

Xia Keyu looked at the three people's backs as they left for a while, pursed her lips and thought for a moment, then picked up the document that had not been processed in her hand and continued reading.

Time gradually came to evening, and I didn't know when the sun in the sky was blocked by the distant mountains, leaving only the afterglow filling the sky.

Xia Keyu stood in the gathering place and stretched lazily with satisfaction.

Finally, all the important things have been dealt with.

Watching the players coming back from the gathering place one by one, she put her hands behind her back, then slowly walked to the center of the gathering place and saw the watchtower.

She looked up for a moment, thought for a moment, and then slowly climbed up.

Tang Yi was sitting on the top of the tower with his eyes closed, as if he was resting or practicing.

After Xia Keyu climbed up, she saw Tang Yi's appearance and sat down beside him carefully.

She looked at Tang Yi's profile for a while, and a smile appeared on her face unconsciously. Then she took a long breath, held her head with both hands, and turned to look at the scenery on the side.

At this time, there were two people sitting on the watchtower, and a small robot stood behind them.

Xiaoxing was also very sensible. When he saw this situation, he silently took a few steps back and went into standby mode on the spot.

The top of the tower was very quiet. Although the noisy sounds from the gathering place could still be heard, Xia Keyu's heart gradually calmed down as she looked at the surrounding environment and felt her hair gently blown by the breeze.

In fact, Tang Yi noticed Xia Keyu's arrival at the first moment. He was very familiar with her footsteps and her breathing.

However, he was writing the update announcement for version 1.3, and Xia Keyu didn't say anything, so he didn't open his eyes.

until……

"Boom."
