Lin Haitian's eyes were clear and he could see very clearly.
This fine carbonite is extremely black and very similar to coal on earth.
However, Lin Hai felt an extremely powerful aura from it, which was breathtaking! "If the prediction is correct, this fine carbon stone should be an excellent material for making weapons!"
Lin Hai suddenly remembered the diamond he had learned in physics class when he was in the mortal world.
Lin Hai still has the impression that diamond, commonly known as "diamond", is a mineral composed of carbon and a particle material composed of simple elements in nature.
Moreover, diamond is the hardest substance found naturally on the earth.
This black carbon stone is also composed of carbon. I wonder how hard it is?
If it's hard enough, wouldn't it be just right for making warships?
Lin Hai always remembered that the warships obtained from the mortal world were still very fragile to practitioners.
However, I have always suffered from the lack of hard enough materials to use.
Although the ten thousand year cold iron is hard enough, it is extremely difficult to smelt.
Mozi and others have been working tirelessly on this, but so far there has been no result.
Maybe, this black carbon stone will be a good substitute! "Hey, buddy, what are you thinking about?"
Suddenly, a middle-aged man with a beard next to Lin Hai smiled at Lin Hai and asked.
Lin Hai finally came back to his senses and smiled back at the middle-aged man.
"I'm wondering what this black carbon stone is used for."
"you do not know?
!”
The middle-aged man was stunned for a moment, looked at Lin Hai in disbelief and asked.
Lin Hai shook his head.
"I really don't know what your name is, eldest brother. Can you tell me a little bit?"
Lin Hai said politely.
"My surname is Liu, and my name is Liu Quan. You can just call me Lao Liu."
Liu Quan said carelessly.
"This black carbon stone is the best material for making weapons. It is not only extremely powerful, but also extremely hard, comparable to a magic weapon!"
"The most important thing is that this material is very easy to smelt, and there is almost no difficulty."
"The only drawback is that it is extremely difficult to mine, but for this reason it is also very expensive."
"This time, the Kang family in Bailiu City purchased fifteen cars at a time, which can be said to be a big deal!"
After hearing this, Lin Hai's eyes suddenly flashed with ecstasy.
Sure enough, he guessed right, this black carbon stone is really an excellent material for refining weapons.
If it can be mined on a large scale, the development of its own warships will no longer be a problem.
"Old Liu, apart from our village, where can we find black carbonite? The bigger the scale, the better!"
Liu Quan was stunned for a moment, then shook his head blankly.
"I don't know about this. I only know that there is one at the south end of our village."
"However, the area is not large. The most important thing is that mining is too difficult."
"oh."
Lin Hai nodded, feeling a little disappointed.
If the area is not large, it will not be able to supply its own warship production.
It seems that we need to inquire more about where there is large-scale black carbonite.
If it doesn't work, you have to find the funny guys in Heaven to see if there are any alternatives.
Liu Quan is extremely talkative and down-to-earth.
Along the way, I talked and laughed with Lin Hai, and the atmosphere was very harmonious.
Unknowingly, the two of them became familiar with each other.
The most important thing is that from the beginning to the end, Liu Quan did not discriminate against Lin Hai at all because of his status as a Sanxian.
At this point, Liu Quan left a very good impression on Lin Hai.
After all, since arriving in Tianwaitian, anyone who meets Lin Hai will be more or less discriminated against because of his identity as a Sanxian.
"After completing this trip, I will earn a hundred high-grade spiritual stones, and my son's cultivation will be successful!"
Liu Quan looked excited when he mentioned the salary for this escort.
From the conversation, Lin Hai also learned that Liu Quan had two children, but both had mediocre qualifications and are still the supreme immortals.
However, they are not far away from overcoming the heavenly tribulation, but with the foundation of the two of them, the possibility of successfully overcoming the tribulation is very small.
The only way Liu Quan could think of was to provide his two sons with enough high-grade spiritual stones.
In this way, the weak foundation of the two sons can be further strengthened, and there will be a glimmer of hope to overcome the disaster.
"It is indeed a top-grade spiritual stone!"
From Liu Quan's words, Lin Hai also knew that his guess was correct, that the spiritual stone was really a top-grade spiritual stone.
It seems that once entering the fourth heaven, everything has been upgraded.
It is completely different from the third level of heaven below! "Everyone, please pay attention, there is a dangerous area ahead, please be vigilant!"
At this moment, Captain Zhu shouted loudly, which shocked everyone's spirits.
Liu Quan's eyes flashed, his true energy was released slightly, and his heart suddenly beat very fast.
"Old Liu, what's wrong?"
Lin Hai asked in surprise.
"Brother Lin, you don't know that bandits are rampant in this area ahead!"
"Whether this shipment can be delivered safely depends on whether it can pass the road ahead."
When Lin Hai heard this, he immediately raised his eyebrows and looked forward.
But now I saw that I was on a long and narrow passage between two mountains.
If someone blocks the road ahead, it will really be impossible to pass.
"Why don't we fly?"
Lin Hai suddenly asked the question in his heart.
"flight?"
Liu Quan smiled bitterly and shook his head.
"Flying is not allowed in the fourth heaven!"
Lin Hai looked surprised and asked in confusion.
"Why?"
Liu Quan shrugged and shook his head blankly.
"Who knows, there has been a no-fly order since the day I entered the fourth heaven."
"If someone flies without authorization, thunder will fall from the sky and chop the person into powder!"
Lin Hai was shocked when he heard this.
Unexpectedly, this fourth heaven is so weird.
"Someone is coming!"
Suddenly, someone screamed and all the vehicles stopped.
"Ready to fight!"
Captain Zhu suddenly shouted loudly, his true energy was suffocating, his aura bloomed, and he looked forward with a solemn expression.
Lin Hai also focused his gaze and looked forward.
But in front of them, dust was flying, the earth was shaking, and an overwhelming pressure was coming towards them.
"It's a cycling team!"
Liu Quan's expression suddenly changed, and cold sweat ran down his forehead.
"Brother Lin Hai, hide behind me for a while and wait and see what happens."
"If I'm defeated, don't help me, just run away quickly."
"I don't regret dying. You are still young, so don't lose your life in vain!"
Hearing Liu Quan's words, Lin Hai's heart suddenly felt warm and he looked at Liu Quan in surprise.
He didn't expect that this man he met for the first time would be so considerate of him.
Lin Hai is also a sweet-tempered person. He always respects me as much as he respects others! "Don't worry, Old Liu, I won't run away, and nothing will happen to you!"
After saying that, Lin Hai's eyes turned cold and he looked at the mighty riding team.
Regardless of anything else, just what Liu Quan said just now, Lin Hai has decided to save Liu Quan! For no other reason than Liu Quan, it’s so interesting! At this time, the cycling team has reached the front of the team and stopped.
Come down.
Looking at the monster with a ferocious face and breath coming out of its mouth, the convoy guards suddenly became nervous and swallowed saliva in their throats.
If they really fight, if nothing else, these monsters alone will be able to swallow them up.
Mu De, if you don't get the spiritual stone, your life may be hanging on here.
The guards were all frightened, with fear in their eyes.
"The team ahead is escorting the fine carbon stone for the Kang family!"
Suddenly, a red-clothed leader took a step forward on a monster beast and shouted loudly.
