Finally, it was the sixth day.

Last night, Li Hao and Lan Xin talked all night, and explained everything that should be explained! Let the golden wolf be the driver and bodyguard of the snow and protect her closely...... Go to kindergarten.

He taught Lan Xin every kind of cultivation technique he knew, and asked her to cultivate by herself, and properly teach her parents and people around her to cultivate! At least to the extent that she was physically strong......

Early in the morning, Li Hao had breakfast, dressed neatly, and prepared to set off for Zhongnan Mountain!

Lan Xin has been holding his hand reluctantly, and the little bird is leaning on his arms.

Li Hao kissed her lightly on the forehead and said, "Xin'er, be good." The family will be handed over to you in the future!"

Lan Xin's eyes were red and nodded: "I will take care of my parents and the company, but Xiaojun ...... there"

Li Hao said: "I have already called her and told her, I will try to come back before the child is born!"

Lan Xin's face was happy: "Then it's only more than eight months?"

Li Hao nodded and said, "The people I care about the most are all here...... Even if it's 10,000 years, I'll be back! You guys, okay, just wait for me!"

He looked at the new watch that Blue Core had bought for him, and said, "It's almost time! I should go! By the way, what about my parents, why haven't they seen me off?"

Lan Xin said: "Mom said that I don't want to see you, a stinky cub, leave home and hide in the room and cry! But don't worry, I'll go to comfort her later, and accompany her to go shopping and buy a few new clothes, and it'll be fine!"

"What about my dad, my dad should come to see me off!"

Li Hao looked left and right, but he didn't see Li Dusheng!

Lan Xin said: "He went out as soon as dawn, and he didn't say anything! I'll call him......

She took out her mobile phone and was about to call Li Dusheng.

"No need to fight! My dad is back!"

Li Hao saw Li Dusheng driving back, and when he got out of the car, he also brought another middle-aged man in a suit, this person Li Hao faced, I had never seen it!

"Xiao Hao. You haven't left yet, that's great!Mr. Nakamura, come on, this is my son Li Hao!"

Li Dusheng pulled the middle-aged man over!

Li Hao was surprised and said, "Dad, who is this person?"

He was very curious, and he didn't know what Li Dusheng was doing when he brought a stranger back at this time.

"Xiaohao, his name is Nakamura Yanagi, and he is the chief technical engineer of the Lingsang Iron and Steel Alliance. There is something very important and very important, and he wants to report to you! You can talk slowly, I'll go in first! Xin'er, go!"

Li Dusheng pulled the blue core and walked into the house, his expression was very serious, and it seemed that there was something very important for Li Hao to discuss with Nakamura Yanagi.

Li Hao suddenly sneezed!

Lan Xin, who had walked more than a dozen steps, said worriedly: "Xiaohao, why did you catch a cold?" It must have been a few days ago when I went to the deep sea to fish for gold pills and got wet, and then I was too busy these days to rest well......

"I'm fine. You go in first!"

After Li Hao saw Lan Xin leave, he looked at Nakamura Liu curiously: "Mr. Nakamura, do you have something to talk to me about?"

Nakamura Ryu took a closer look, there was no one nearby, and mysteriously took out a piece of iron from his arms, handed it to Li Haodao: "Mr. Li! This is the new alloy ...... you handed over to our technical research laboratory for research and analysis."

Li Hao nodded: "Yes, what's wrong?"

He almost forgot about it!

After acquiring the Lingsang Iron and Steel Alliance Group, he handed over the fragments of the Xuantie manhole cover in the Holy Mountain Soul Lock Well to them and let them study and analyze the samples!

But then he was so busy dealing with Zhao Gao that he forgot about it!

But he didn't understand, he was going to the secret realm, what did his father Li Dusheng bring this guy to do at this time? Could it be that the Xuantie analysis sample has a very important result?

Nakamura Yanagi mysteriously took out a few other pieces of dark iron from his pocket, which looked similar to Li Hao's piece, but the luster was a little surprised......

This piece in Li Hao's hand is even darker!

"What is this? How can there be so many...... "Li Hao is also puzzled!" "Mr. Li Hao, I won't tell you anything. Our technical laboratory accidentally obtained some samples of dark iron more than ten years ago, and has been secretly researching it. Since you got your sample, the biggest breakthrough and progress has finally been made! Here are five samples, all of which are dark iron.

And this piece you gave us is the highest level...... I'll call it 5-grade black iron for the time being. The others are 1, 2, 3 and 4. ”

In his hand, plus the piece in Li Hao's hand, there are just a total of 5 pieces of dark iron fragments!

Li Hao said in surprise: "Is there any difference between these 5 fragments?" Nakamura Ryu said with some excitement: "We have always had samples of the first four grades in our hands, but we don't have samples of 5-grade Xuantie, so we have never been able to understand the composition of Xuantie." After getting the sample you handed over and analyzing it thoroughly, we learned that the 5-grade dark iron is the real highest-grade dark iron, with a complete high-density chimeric structure, this structure is very special, not only makes the dark iron harder and lighter than ordinary steel alloys, but also seems to be able to lock in energy in a special way! For example, the 5-grade dark iron in your hand, such a fragment as big as a fingernail, actually makes a 100

The light bulb of the tile lasted for 16 hours!"

"What? The structure of the dark iron has its own energy, and it can also be converted into electrical energy? If this material is used in electric energy vehicles, won't a car be able to drive 5,000 kilometers without charging?" Li Hao was completely surprised! "No! Mr. Li Hao! If there is a little bit of light energy composite molecular material in the dark iron structure, it can automatically supplement solar energy and convert it into electrical energy...... Do you know what this means? This means that we are solving the new material and new energy problems that plague the world at the same time!

You think, we don't need engines to run cars, and we can even invent spaceships that run forever...... Oh my God! This is simply incredible! Although there are still many technical difficulties to overcome, as long as we can produce this kind of 5-grade dark iron......

Nakamura Ryu looked at Li Hao with a frozen face!

Li Hao smiled: "If you have something to say, just say it!" Nakamura Liu said: "But with the earth's current smelting technology, there is no way to mass-produce this kind of 5-grade Xuantie! Mr. Li Hao, I know that you are about to go into retreat and cultivate! I really need to know, where did you get this high-grade Xuantie? I really can't wait for a few years, this."

It's a big turning point that wants to change the course of humanity......"

"Oh!"

Only then did Li Hao understand why Li Dusheng was in a hurry to bring this guy to see him!

It turns out that he wants a lot of 5-grade black iron!

It's a pity that he doesn't have it in his hand!

He smiled slightly and said, "I'm sorry, I do have a large amount of this 5-grade Xuantie, but I can't hand it over to you! You should study and overcome the relevant technical problems first, and when I come back from retreat, I will go back to you!"

"Mr. Li Hao, but ......"

"Didn't you hear me? Goodbye, Mr. Nakamura!"

Li Hao exerted his skills and was about to step away!

"Xiao Hao! wait!"

Lan Xin suddenly ran out in a hurry, gave him a very hard hug, and then quietly stuffed something into Li Hao's coat pocket......

"Xin'er, wait for me!"

"In this life and this life, I will wait for you! In the next life, I will also wait for you!" The moment Lan Xin let go of Li Hao, he couldn't help but burst into tears......

"Take care!" Li Hao couldn't bear to look at it anymore, and with a teleportation, he rushed into the vast void!!
