Lu Zi came to the side of his master Wu Liang after eating, and Jiabao dug a spoonful of egg custard and bit it into his mouth and looked at Lu Zi. His little face was glued to the grains of rice.

"Master, have you noticed?" Xu Yan was not very happy. ”

"The experiment is messed up, who can be happy?" Wu Liang didn't even look at Lu Zi. His heart was not happy. The topic of this experiment was proposed by myself. Uncle Shi and Xu Yan studied for half a year, but now it has been shelved because of material problems. Not to mention the large amount of money allocated above, it is the significance of allowing the space guard to leave the spacecraft and return safely, which makes everyone reluctant to give up research. But there really is no way to go on unless you find a material that blocks the strong magnetic force. Wu Liang's eyes were staring at his rice bowl, and he really couldn't eat the last bite of rice.

Lu Zi didn't ask any more questions as soon as he saw the master's expression. He asked Yuwen Tuo later. Yuwen Tuo only said that the new spacesuit design experiment lacked a material that could block the strong magnetic force, and was shelved.

Lu Zi returned to his room and took out the gold-absorbing stone and looked at it. Xu Zhi wanted to take it and take a look, but he wouldn't let him. Xu Zhi said What is so beautiful about a broken stone! Lu Zi ignored him and continued to look at the stone with a black surface and a little sand gold.

Xu Zhi opened his phone and looked at the news inside. Suddenly, Lu Zi jumped to the ground and ran out. Xu Zhi was stunned for a long time, not knowing what happened to Lu Zi today.

Lu Zi ran to the rest hall to find Xu Yan. Xu Yan was not there. Fang Xin frowned when he saw Lu Zi running in in a hurry. This Wu Liang's apprentice is worse than the apprentice taught by the senior brother in terms of calmness!

"What's so urgent?" Fang Xin asked patiently.

"I, this stone. I'm looking for Xu Yan. "Lu Zi is somehow afraid of this uncle. Maybe he was scared of Fang Xin's punishment.

"What stone?" Fang Xin's eyes looked at Lu Zi's hand. The black, gold-tinged stone caught his attention.

"Show me!" Fang Xin walked over to the table and sat down. Lu Zi hurriedly put the gold-absorbing stone in front of Fang Xin.

"Where did it come from?" Fang Xin looked at the stone carefully.

"It's a gold-absorbing stone. When we went to the north to find Quba, he used it to get rid of the demonic nature. The master said that since it can remove the demonic nature, it may be useful to you, uncle. Lu Zi said a lot of words in one breath.

"Where did you find it?" Fang Xin's heart was a little excited. This stone may be what they need.

"The old Montenegro of Yanji. ”

"Go and find your master and Xu Yan. Although Fang Xin's heart fluctuated, his surface was very calm.

"Yes!"

When Lu Zi went to find Wu Liang, Wu Liang and Jiabao were lying on the bed learning cow topping. Lu Zi was happy to see it.

"What's the matter?" Wu Liang asked, picking up Jiabao and sitting up.

"Uncle Shi is looking for you! I still have to go to Xu Yan. Lu Zi turned around and ran out. Heh, the master is really interesting.

When Wu Liang came to the rest hall, he saw Xu Yan and his uncle sitting at the table drinking coffee. Xu Yan swept away the gloom of the past, and her face was filled with a happy smile.

"Is there anything good?" Wu Liang sat down at the table with a big grin. He already had a steaming Coke in front of him. Wu Liang held the Coke cup in both hands, but his eyes looked at his uncle Fang Xin.

"Is the output of this stone mine large?" Fang Xin pushed the gold-absorbing stone in his hand to the middle of the table.

"Hmm!, does it work?" Wu Liang asked curiously.

"Why didn't you take it out earlier? Xu Yan's words made Wu Liang understand the importance of this stone.

"Are you saying it's the material you need?" Wu Liang also became excited. There's a door for experiments!, he cried out in his heart.

"Tomorrow we will go to Great Black Mountain together. Fang Xin drank all the coffee in the cup.

The snow cover in the Great Black Mountain has not yet completely melted. Fang Xin actually came here in person this time, which surprised Wu Liang. It seems that this research is really important to Uncle Shi. Xu Yan, Wu Liang and Lu Zi followed behind Fang Xin. Lu Zi occasionally pointed in the direction. After they arrived at the gold mine, Wu Liang and Lu Zi sat on the stones. Fang Xin and Xu Yan surveyed the ore with joy on their faces.

Wu Liang found that after walking such a long mountain road, his uncle Fang Xin's pants were still snow-white, and there was not even a single mud spot. After Fang Xin made a phone call, he picked up a few gold-absorbing stones, put them in a bag, and threw them to Wu Liang. Lu Zi took the bag from his master's hand and carried it on his shoulder.

Then, everyone hurried down the mountain together. When he arrived at the bottom of the mountain, Wu Liang found that the intersection of the mountain was sealed. There were two more people on guard.

Fang Xin said a few words to the two guards. Wu Liang stood far away, embarrassed to lean in and listen. He was curious to know what they had said.

"Wu Liang, you two stay here and supervise the mining of ore. Let's go back and do some research first. After Fang Xin finished explaining, he and Xu Yan took the bag in Lu Zi's hand and got into the car and left. Wu Liang scratched his head and looked at the mountain helplessly.

"Master, let's find a hotel in the village and stay in the village. Lu Zi looked at the sky and said that it was getting late.

"Hmm!"

Wu Liang's master and apprentice entered the village and stayed in a small hotel. Now that there is no heating equipment, Wu Liang and Lu Zi feel that the inside of this house is not much warmer than the outside.

They had to sit and meditate and practice. When it was dawn, the two went to eat at the only restaurant in the village. The conditions here are relatively difficult, and Wu Liang and Lu Zi are no more than that. So they didn't feel any better.

In the past two days, the mining team has not arrived, and Wu Liang and Lu Zi have nothing to do and wander around the village. Aunt Wang in the village looked at the two young people and liked it. She opened the courtyard door and asked them to sit in her courtyard. Wu Liang and Lu Zi were not easy to push, so they entered the courtyard.

Aunt Wang has a dog in her yard. It saw the stranger pounce on it. Wu Liang and Lu Zi couldn't help but take two steps back. Aunt Wang stopped drinking it in time. Although the dog didn't move again, its two eyes were glaring at Wu Liang and Lu Zi, and its mouth was still barking softly from time to time.

Aunt Wang let them go to the hot kang and brought them melon seeds. Wu Liang and Lu Zi felt that this hot kang head was good, which made people feel warm.

"Auntie, are you alone at home?" Wu Liang asked.

"Just one person! They've all moved to the city. Aunt Wang picked up a few hot roasted sweet potatoes in the stove and wrapped them in paper and took them.

"Eat, where do you live?" Aunt Wang quickly put the sweet potato on the table. Then she went to see the fire in the stove.

"We stayed in a small hotel at the east end of the village. Wu Liang was almost burned by sweet potatoes.

"Master, eat slowly, no one will rob you. Lu Zi quipped.

"I can't stop your mouth when I eat it!" Wu Liang blew on the peeled sweet potato. The sweet potatoes are yellow, sweet and delicious.

"Come, drink some hot water, don't choke. Aunt Wang brought two bowls of water. She wiped her hand on her apron.

"Aunt Wang, you are alone in these three rooms, why don't we rent your house to live in?" Wu Liang put the sweet potato peel on the paper.

"My kang is much warmer than the bed in the hotel!" Aunt Wang smiled.

In the afternoon, Wu Liang and Lu Zi left the night and stayed at Aunt Wang's house. When Aunt Wang saw the two children, she remembered her son and daughter. She took care of them as if they were her own children. Wu Liang gave her money, but she said she didn't want anything. She said that the money her children gave her had not yet been spent.

The mining team is coming. Wu Liang and Lu Zi got busy. They have to oversee the work! This is the task given by Uncle Shi. When transporting and loading, Wu Liang and Lu Zi also had to check them one by one. Boss Wu, who is in charge of mining, said that it is rare for a young man like them to be so serious.

Half of this gold-sucking mine is above ground and half underground. Fang Xin told Wu Liang that it would be okay for them to mine the above-ground parts. Do not move the underground part and fill it with earth.

A month later, the mining was completed. Wu Liang did a good job of dealing with the aftermath according to his uncle's instructions. Then they said goodbye to Aunt Wang and set out on their return journey.
