Two days later, the group returned to Dujia Village.

Wu Kesong dismissed the four young men and promised them that they would give each of them a good steel knife and a good bow and arrow in the future.

Wu Kesong took Gu Cheng, Du Wu, and Murong Feng back to his two thatched houses. Murong Feng and Du Wu put down the trailing meteorite. Wu Kesong also put the Heart of the Stars into the house first. The four of them sat on the ground in the shade of the tree at the door.

Wu Kesong opened his mouth and said, "Senior brother, I am extremely simple here, I used to live by myself, but now that you have all come, these two grass houses are a little cramped, there is a bamboo forest behind my house, and there is a clear stream, it is very quiet, why don't we cut down bamboo and build a house, build several bamboo houses in front of the bamboo forest, and teach two children every day, do you think it's good?" Gu Cheng had already lived a very simple life when he was in the Northern Desert, and of course he had no opinion when he heard the words, and he clapped his hands and praised it.

So they discussed, Du Wu first went home to visit his parents, told them what had happened, and then came here every day to study.

Du Wu then returned home, and Du Sanlang and his wife were of course extremely happy to see the child come back. first asked why Du Jingzhong didn't come with him, and when Du Wu told the uncle that he was going to leave in advance, San Lang couldn't help but be sad for a while. Du Wu told her father and mother (she didn't know her background at this time) that she would invite her father to the master tomorrow, and the master would discuss some things with him. Saburo nodded yes. The couple pulled Du Wu to ask long and short questions, and when they heard the general process of their trip, they couldn't help but be surprised and happy.

The next day, San Lang came to the blacksmith's house with Du Wu and met Uncle Wu, who introduced him to Gucheng. Saburo hurriedly saluted again. Wu Kesong asked Du Wu to go with Murong Feng to the back of the house to cut down bamboo, prepare to build a house, and then sit down with Gu Cheng and Du Sanlang to talk.

Wu Kesong explained to San Lang the identity of himself and Gu Cheng, after all, San Lang had been a petty official in Fucheng for some time, and he had some knowledge, and he had heard the name of the Great Heavenly Demon, as for the Black Dragon National Teacher, it was even more like a thunderous and famous figure in the mainland. Hurriedly stood up again, knelt down and kowtowed to the two old men again. The second elder hurriedly helped him up.

Wu Kesong explained Du Wu's origin to San Lang again, and San Lang knew that his daughter turned out to be the little princess of the Southern Barbarian Kingdom. After explaining everything, he told San Lang that he would still make farm tools and other iron tools for Dujia Village. At the same time, the two brothers wanted to teach Du Wu and Murong Feng martial arts. Du Saburo suddenly remembered his own son Du Wen, and pleaded, "The two seniors, to be able to come to my Dujia Village, is the blessing of my whole village, and the younger generation has a reluctant request, my dog Du Wen, is also seven years old this year, can he also learn martial arts with the two old-timers, if the second elder does not give up under the door, my whole family is grateful" Wu Kesong muttered and said, "It is okay to teach him some martial arts, you can ask him to come with Wu'er tomorrow, I and my junior brother will first see how his roots are, as for whether he can be included in our door, it depends on whether he is related to us." When Du Saburo heard this, he hurriedly thanked him.

After Du Saburo left, Wu Kesong said to Gu Cheng, "Senior brother, you first take Feng'er Wu'er to cut down bamboo and build a house, I want to start exercising this meteorite and the heart of the stars, and start to build weapons for the children, but as I expected, the meteorite is just that, and the difficulty of forging the heart of the stars must be extremely difficult" Gu Cheng hurriedly asked why.

Wu Kesong said, "This forging method is to burn the ore in the furnace to soften, while it is hot with a sledgehammer to keep tempering, refining the impurities, if you need to refine the alloy, you need to melt the raw materials and mix them together in proportion, and then start forging after cooling to a certain temperature." It's just that the texture of this heart of the stars is so fine, the melting point must be extremely high, otherwise it will not come out of the liquefied meteorite. I don't know if the temperature of my furnace can soften or even melt it, if not, we will have nothing to use. Gu Cheng was also anxious when he heard this, but he heard Wu Kesong say again, "If I can't melt it with this iron furnace, it's not impossible to think, but I just have to find a better fire source." After all, the predecessors had the experience of forging with the heart of the stars. It shows that the heart of the stars can still be burned. It's just that as far as I know, the fire source in the five countries of this continent is hotter than mine, alas, ......" he couldn't help but sigh and become annoyed.
