When the thunder dissipated, and the residual Rongdu, who was still covered with wounds and blood, landed on the ground, the afterglow that had just survived the Heavenly Tribulation Thunder Punishment sensitively felt a gust of wind, and then saw the green vine snake. {Starter}

With concerned eyes and a nervous look, if it weren't for the fact that there was a green green snake in front of him, Yu Rongdu must have thought of the classic image that impressed him when he watched the movie back then, the green-clothed Xiaoqing in the legend of the White Snake.

Seeing the green vine snake, the nervous heart suddenly quieted down, and the relaxed body turned into the original body of the horned viper, and then fainted, before the coma, Yu Rongdu's last thought turned out to be: Since I am a demon snake, and at this time, will the white snake be far away, will Xiaoqing be far away? I just don't know if Xiaoqing is a green snake or a herring fish, so confused......

The nascent morning sun shines on the East African savannah, but a white ground appears in the middle of a lush grassland, and the black carbon embers indicate that there has been at least a fire here, and the grassland without grass is naturally not treated by other animals. As a result, many animals have taken a detour.

They didn't know that this place had been struck by lightning last night that they had never been able to do in their lifetime.

In the center of the clearing, there was something very conspicuous, a turquoise green snake that stood out in the black embers. Beside it is an African horned viper that is pale blue and begins to glow with an earthy yellow. Or a horned viper with four claws.

Two snakes, who were supposed to be thousands of miles apart and had completely different living habits, were coiled together.

What a strange scene.

The sun gradually rose, and the snakes, which were cold-blooded animals, began to regain their vitality, but at this time, the green vine snake woke up, and then straightened itself up, and looked at the African horned viper with concern. However, seeing the indifferent sleeping appearance, the nervous green vine snake relieved his heart and looked blankly at the four-clawed African horned viper that was sleeping.

Noon is approaching, which means that the hottest time in the East African steppes is about to arrive. The two snakes, which were still quiet, were broken by the voice of a little Lori.

"Come on, I've found my big brother...... "The green gold gourd Ziwen was suspended in the air and shouted around.

The voice was transmitted at a very fast speed. And Yu Rongdu was also woken up by this voice, the first thing he saw was the green gold gourd Ziwen who was dancing in the air, and then he saw a pair of concerned eyes next to him, if it wasn't for the appearance of the green vine snake, Yu Rongdu would feel more comfortable.

Instantly reverted to its human form. Although he knew that the snake body was not a big deal, Yu Rongdu knew that as a snake body, he would sometimes act according to his feelings. This is the same as the inexplicable closeness between the green vine snake and himself, the smell of the same kind, the smell of the same kind, the feeling of the same kind......

Smiling, he lowered his head and glanced at the green vine snake, revealing a bright smile, and stretched out his index finger with a smile to point at the center of the green vine snake's eyebrows, but it was quite casual to pass on the wood method in the Great Five Elements Technique to this spiritual little snake. I don't care about the origin and preciousness of this spell.

Since this strange green vine snake is so close to him, and has such a magical appearance in speed, he naturally wants to pass on his wood method. Among the five elements, the wood method extends the wind, and the wind master is speed.

Thinking about it, I am afraid that in the future, I may not be able to compare with the speed I am now just a slightly spiritual green vine snake, and Yu Rongdu felt funny.

I'm afraid, there is still a long way to go.

Then he turned to look at the Heavenly Jue, the Blood Transformation Divine Sword, and the Ruyi Qiankun Bag that were speeding from all directions. At this time, Yu Rongdu realized that he was far away from the retreat. But he didn't expect that he would fly so far in a hurry, and it seems that there are still many things to pay attention to when it comes to cultivation in the future.

Looking at everyone in such a hurry, Yu Rongdu suddenly felt a faint warmth, because in his previous life, he had a team that was very harmonious, friendly and loving to each other, and it was that team that made him step by step towards the highest peak of science.

And now, looking at these people, although he knows that they are all magic weapons, and now they are all illusory shadows, Yu Rongdu has a feeling that they are all living people, and they are all his friends.

It's nice that only people have feelings. Yu Rongdu thought slowly in his heart.

Seeing that they were all gathered, Yu Rongdu smiled and bowed his head with them one by one, and then didn't say anything, and walked back first, but before leaving, he glanced at the green vine snake behind him. The green vine snake first showed a look of surprise, and then followed Yu Rongdu all the way, but when Yu Rongdu saw the green vine snake behind him, thinking about his speed, he felt so boring.

Returning to the original place, looking at the humble retreat, Yu Rongdu felt the urge to cry, thinking that back then, his real room had always been the most sophisticated and advanced place, and now, he even had to open air......

With a long sigh, Yu Rongdu has started a boring cultivation, in the previous life, he was endlessly doing practical yàn, doing research, and in this life, Yu Rongdu is still an endless cultivation. It takes a lot of repetitive and boring movements to achieve the goal.

It didn't take long for the golden aura in the small iron mine itself to be so thin that some ordinary plants and trees grew a little sparsely.

In desperation, Yu Rongdu continued to want to move eastward, and encountered several small iron mines one after another along the way, and in the face of the autumn wind sweeping away the leaves, he had to reluctantly sacrifice the environment.

When the very keen senses that had been cultivated lightly touched a little salty and moist air blowing from the east, Yu Rongdu knew that there was the Red Sea ahead, but at this time, the joy of seeing the sea was replaced by another happy event.

Gold mine!

If a metal mine like iron ore has a gold aura, then a gold mine is where the gold aura is pure. It wasn't until the discovery of this gold mine that Yu Rongdu remembered that there were several gold mines in the northeast and south of Sudan.

Books are hated less when they are used. Yu Rongdu does feel a little bit about the education of the previous life, and a lot of seemingly useless homework information is sometimes really useful, such as now. It's just that that world can be traversed, and there are too few people who cultivate immortals, almost none.

Seeing the gold mine, Yu Rongdu knew that his cultivation was coming.

Practicing the Golden Exercises. The first choice is this kind of gold mine, and choosing iron ore by yourself is the beginning of cultivation, and it is also because you don't remember the helpless choice when you have a gold mine. And now that he knows where the gold mine is, he naturally has to cultivate well.

Still painful, a little bit of bone replacement, the ancient Gong scraped the bones to heal the wounds, but now the residual tolerance is not just a matter of scraping the bones, but a little bit of grinding his own bones, and then using the golden aura to fuse, a little bit of fusion, and finally replace those original bones, the pain in it is just look at his piece of spirit stone crystal mountain.

With Yu Rongdu's current strength, there is only a shallow trace, but now, after so many days of cultivation, Yu Rongdu of pain will use his claws and claws to bite with his teeth when he really can't bear it, and forcibly transform the top of the Crystal Mountain into a cultivation groove that is more than enough to allow a normal person to sit cross-legged.

When the gold mines in the entire northeast of Sudan contained tens of millions of years of golden aura were absorbed by Yu Rongdu, Yu Rongdu also reached the point that one-third of his bones were all replaced by golden aura, and it looked like some kind of mysterious pattern densely wrapped around his bones.

Now is the time to decide, is it to go east, with the Red Sea leaving the Strait of Holmts through Somalia to the Arabian Sea and returning to the Central Plains, or to turn south and follow the Great Rift Valley to southern Sudan and continue to cultivate?

At this time, looking at the Red Sea as far as the eye could see, Yu Rongdu was very entangled and unable to decide.

There is only one green gold gourd Ziwen who doesn't care about it, and she still has no heart to run around, seeing the afterglow in a daze, but the lapis gourd Ziwen is thumping over, pulling the arm of the remnant, and asked delicately: "Big brother, you say, why are they the same iron and gold, both metals, why is there such a big difference in the aura they contain?" The gold aura of the gold mine is really rich, and it has given birth to such a good thing as the near spirit fruit, although it is not ripe, but the sweet and sour is still very delicious, I have eaten it with Xiaolu and Xiaolu, and Xiaolu still wants it from me, but unfortunately I found three. Big brother, you said that if we can find a place with a particularly abundant golden aura and plant so many dozens, we will definitely be able to eat enough of the golden spirit fruits that grow!"

Jin Lingguo, eat enough...... I'm now practicing the Golden Sex Exercises, and you have a spiritual fruit like this, not to mention giving it to me first, but actually giving it to two animals who have just had spiritual intelligence......

Loser.

Well, too. It stands to reason that they are all metal ores, and their gold aura should only be related to their reserves, but in fact it is obviously not, what is the reason for this?

Yu Rongdu couldn't do anything after thinking about it for a long time, and said helplessly: "I don't know this question either." So what do you think about this?"

The lapis gourd Ziwen said innocently: "I thought it was because gold was heavier than iron." ”

Gold is heavier than iron, and gold is heavier than iron!

The sentence was like lightning flashing through Yu Rongdu's mind. By the way, we know from the most basic chemistry courses in later generations that the reason why metals are different is because of their atomic numbers, and their weights are different because of their atomic masses. The atomic mass of iron is only 56, but the atomic mass of gold is 197.

So, does it mean that its atomic mass determines the amount of golden aura it contains?

So what other mines are there around here? metallic, or is it more atomically massive than gold?

Uranium ore!

To the south, there are gold mines in southern Sudan, and in the south is Ethiopia, although this country is poor and underdeveloped, but later generations learned from a certain news that Ethiopia is more valuable in addition to gold mines, but also uranium mines.

Uranium mine in Oromo State, Ethiopia.

Uranium, but it is a radioactive substance, a metal, with a large atomic mass. Gold has an atomic mass of only 197, while uranium has an atomic mass of 238.

So will it have more golden aura? Yu Rongdu, who was secretly speculating, had already secretly made up his mind to turn south and return to the east.

Yes or no, go, don't you know?

Practice is the only criterion for testing truth. The heart of Yu Rongdu, which had come out of the research mentality of the previous life, began to beat violently, and a rigorous spirit of being a scientist arose.

Science can serve a qiē, including the cultivation of truth. Beechcraft Tip: How to quickly search for the books you're looking for
