Xu Bao waved his hand to stop the people behind him from moving forward, and asked Wang Jian to pass the evacuation order to the rear.

After everyone was completely inside the cave, Xu Bao finally walked out of the cave and saw everyone looking at Xu Bao.

Xu Bao knew that everyone in front of him was puzzled why he suddenly had to evacuate from the cave.

Xu Bao smiled: "Because the cave is moving deeper and will cause harm to all of us, I will let everyone evacuate from the cave now." ”

Wang Jian asked, "Big brother, since you know that there is danger in the depths of the cave, how can we build a weapon to smelt that piece of cold iron?" ”

Xu Bao was also worried, because the gas in the depths of the cave would cause harm to people's bodies, but if he didn't enter, he couldn't smelt this piece of cold iron, and if the cold iron couldn't be smelted, then the weapon he designed couldn't be built.

Xu Bao pondered, Xu Bao flipped through the knowledge he had learned in the future in his brain to see if he could enter the depths of the cave.

Xu Bao's mind was constantly running, and suddenly Xu Bao thought of a good solution.

shouted: "Wang Qian, do we have something like a thick bamboo tube in the country?" ”

Hearing his eldest brother's words, Wang Jian asked suspiciously: "Big brother, why are you asking the bamboo tube?" Doesn't this have anything to do with going into a cave? ”

"You stinky boy, why do you have so many questions? I asked you if there is a bamboo tube I want in the Patriotic City? Xu Bao asked.

"Big brother, there are those kinds of things in Weiguo City, I don't know how thick the bamboo tube is for the big brother?" Wang Jian asked.

Xu Bao thought for a moment and said, "As thick as the bamboo tube, the more the better." Now you take a branch of people to find the thick bamboo tube, and there is one more thing, you go back and tell your sister-in-law to gather the craftsmen here. And let the blacksmiths in the mansion also come over and do these things quickly. ”

When Wang Jian heard what his eldest brother arranged, he was very curious and puzzled, but since it was arranged by his eldest brother, it must be useful, so he didn't dare to ask more, so he had to hurriedly take some people back to Weiguo City.

After Wang Jian left, Xu Bao walked back and forth at the entrance of the cave, thinking about something, and suddenly turned to the blacksmith master who followed him and asked, "Master blacksmith, if you smelt cold iron from here, how about making weapons from here?" ”

When the blacksmith heard Xu Bao's words, he asked, "Childe, if you build weapons from here, how can you build weapons without those forging tools from the blacksmith workshop of the mansion here?" ”

Xu Bao smiled and said, "Master blacksmith, you don't have to worry about this, I will send someone to transport the things you need here, and I will build a forge here." ”

When the blacksmith heard Xu Bao's words, he was surprised: "Childe, do you really want to build a forge from here?" ”

"Of course it's true, what's wrong, there's a problem?"

Xu Bao replied.

"Childe, it's not that there's anything wrong, but this cave doesn't know when it's going to erupt, is it safe?" The blacksmith said.

Xu Bao smiled: "Master blacksmith, you don't have to worry about this matter, I only have a way to prevent this cave from spewing flames." ”

When the blacksmith heard Xu Bao's words, he was very surprised in his heart, and the son had a way to make this cave no longer breathe fire, it felt incredible, and the blacksmith had a surprised expression on his face.

Xu Bao saw the expression on the blacksmith's face, and said with a smile: "Blacksmith master, you don't have to worry about any problems. ”

The blacksmith actually wanted to see what the master he was following was capable of keeping the cave from spewing flames.
