Just after Chen Jiu and Qin Chuan announced the next stage of the refugees' mission, Wig and Chong Niang also came online one after another. As soon as they heard that Qin Chuan was going to build a reverberatory furnace, Chong Niang became excited immediately.

"Let me do this! Isn't it my old job to do civil engineering?"

"If you want to build a reverberatory furnace, you must first have refractory bricks. The material of the refractory bricks is not just clay, but high alumina bauxite."

"I've seen this stuff in the creek at the edge of the woods. You can just let the refugees dig it."

"But the snow is a bit thick now. It will be difficult to dig out. If we really need to do a lot of infrastructure construction, we probably have to push the outpost over there."

Hearing this, the remaining three people couldn't help but scratch their heads.

Let alone opening a new outpost, it is actually not easy to maintain even the existing base.

The main problem is safety. Chidiji is not like the prosperous era they lived in. Wild beasts in the mountains and forests can be said to be overrun. Without modern firearms, the wilderness is extremely dangerous.

Even though most wild animals are afraid of humans, if you are unlucky enough to encounter a ferocious predator such as a lynx or a black bear, you may lose more than one or two people.

It is possible that the entire outpost could be wiped out.

"Oh oh oh, it's better not to build a base. Hebend is not far away. You can use fireworks to defrost it. I know this!"

Wig interjected proudly from the side.

"It's not impossible. There happened to be a lot of dry grass over there, so I just set it on fire to clear the working surface."

The insect girl nodded and accepted the wig suggestion, then continued:

"The heat loss of the reverberatory furnace is very large. Generally speaking, it is necessary to install a waste heat recovery device, but it is definitely not possible with our current technology. Why not directly lay heating pipes and introduce the waste gas?"

"Ah? Then isn't this a paradox?"

Upon hearing this, Qin Chuan was unhappy.

Originally, the purpose of building a reverberatory furnace was to make iron and solder aluminum, and the purpose of iron and soldering aluminum was to make a large electric heater. If you solved the heating problem in the first step, what is the use of making an electric heater?

He expressed his thoughts, and the other three fell silent.

After a while, Chen Jiucai spoke:

"This is not a complete paradox. After all, the heat energy provided by the reverberatory furnace is limited, but the heat energy provided by the electric heater is unlimited."

"And as you said, electricity-based technology has a stronger impact on refugees and can arouse their admiration."

"What's more, climbing the technology tree itself is also a part of the game. It is definitely right to lay the foundation in advance."

In fact, what he did not say is that regardless of whether Qinchuan's idea is useful at this stage, as long as he can build a set of primary iron smelting facilities, the "technological level" in Shuanghe's assessment standards can be improved.

Climb a lot.

This is necessary to obtain higher level permissions.

Not to mention what the technology brought by high-level permissions can bring to you and the players in reality, even for the task of rebuilding the red land itself, higher-level technology and higher-level equipment are also extremely important.

Otherwise, can we really conquer the world with just a few bows and arrows?

This world is not a simple medieval world. The technologies left behind before the end of the world have completely transformed the world, making the people of Chidi who inherited the technological heritage extremely dangerous.

Without strong firepower, development and conquest are impossible.

But Chen Jiu couldn't tell Qin Chuan these words, mainly because it would ruin their gaming experience.

Fortunately, he didn't need to say anything, just a few words were enough to convince Qin Chuan.

"Okay. Let's do this first."

"But I have another idea. Since we have to use waste heat, can we use this waste heat for farming?"

Hearing his question, Wig shook his head repeatedly.

"No, no, no, geothermal heat alone is not enough. Air temperature has a great impact on plant growth. Anyway, there is no need to think about it before there is no transparent material. Let's just grow mushrooms."

"That's true. How about using waste heat to burn glass? We already have high alumina, so it's not difficult to burn glass, right?"

".Do you know?"

Chen Jiu asked helplessly.

"I don't know how, but I can learn! There are no experimental conditions here. Will there be any when I get offline?"

"Hey, I'm going to play with the equipment during the weekend tomorrow."

"Oh, you really don't have a girlfriend."

Wig said meaningfully.

"Don't make it sound like you have a boyfriend. Girls with boyfriends won't be online every day. They have a lot of activities at night."

"Xisuo!"

The insect lady on the side interrupted abruptly.

"Tell me more about the hammer and get to work quickly. The Buckwheat Field dungeon has been opened. I plan to go explore it today."

"Hey, where is that NPC? Why hasn't she come yet?"

Qin Chuan impatiently climbed to the heights of the camp and looked in the direction of Xiahe Village.

During this period of time, since Lin Shuang basically had to go back and forth between Xiahe Village and the research institute camp every day, an obvious road had been opened in the Ten Thousand Cave Forest. When Qin Chuan looked at the road, Lin Shuang

The figure happened to appear in his sight.

"Damn it, whatever you say comes, is this plot also triggered by keywords? As soon as I decide to do the plot, the NPC will automatically refresh?"

This is just a coincidence!

Chen Jiu thought helplessly.

But let him think what he wants, as long as he doesn't plan to get stuck.

However, before this idea had even finished turning around in Chen Jiu's mind, he heard Qin Chuan continue:

"If that's the case, that would be awesome. Teleporting regardless of distance."

"If we want to take the NPC somewhere in the future, we only need to accept a mission first, then trigger a keyword to spawn the NPC, and it will be done soon?"

Chen Jiu was stunned for a moment, and after a second of silence, he said with a hint of ridicule:

"No planner with cerebral palsy would make such a big bug."

"That's not necessarily true. Does this game have few bugs? It's just that we haven't encountered any vicious bugs yet. Anyway, I don't think the level of planning is too high."

Then do you know that the low-level planner you mentioned is standing in front of you?!

Chen Jiu was too lazy to talk to him any more, leaving him waiting for Lin Shuang to "trigger the plot", while he walked to the refugees who were preparing breakfast and said to them:

"I have explained your new mission clearly before. If anyone doesn't understand, you can ask me later."

"But now, I need your help."

"We need to go to the river bend to collect soil and transport it back to the camp."

"If anyone is willing to join this mission, you can sign up with me now."

"Just like cutting down trees, we will exchange dried meat for the soil you bring back."

"Every 100 kilograms of soil can be exchanged for 1 kilogram of dried meat."

"I will keep you safe."

"Now, if you are willing to go, please raise your hands."
