Xiang Nan weighed the five high-level Holy Spirit Stones and said, "These numbers are not bad, but I still need more."
Big Snake said: "It takes 60 lower-level holy spirit stones to upgrade from the seventh level of Shenwu to the eighth level, one hundred and twenty-eight yuan from the eighth level to the ninth level, and two hundred and fifty-six pieces from the ninth level to the martial saint."
"The total is four hundred and forty-eight pieces. Your five high-level Holy Spirit Stones are just enough for you to be promoted to the first level of Martial Saints."
"However, these five yuan are indeed not enough. In the future, each small realm will require more holy spirit stones. If the Martial Saint doubles from the first level to the second level, then it will need five hundred and twelve yuan."
Xiang Nandao: "Yes, if you want to upgrade to Baihuanyi's level, you need too many Holy Spirit Stones."
"With my personal ability, it's a bit difficult to gather so many Holy Spirit Stones."
For other people who are strong in the next generation, they have the entire Bai family behind them to support them, but Xiang Nan can only rely on himself.
This golden-blooded beast is quite powerful, but it can't be taken out of the Eternal Secret Realm, so it can't help Xiang Nan from the outside world.
You still have to rely on your own strength.
And after experiencing so much, Xiang Nan only believes in himself, and only his own solid strength can make him feel at ease. All the strength obtained by relying on external forces may be lost at any time.
"There are so many silver-blooded beasts in this small secret realm, can you feel their presence? If possible, hunt and kill as many as possible." Xiang Nan said.
Big Snake shook his head and said, "I can't feel it, so I can only take one step at a time. Let's try my luck."
Xiang Nan nodded, and he looked into the distance. According to the magnetic field analysis, he was about one-third of the distance from the true north.
If calculated according to the current speed, it will take at least another five or six days to fly.
But now that there are golden-blooded beasts, he doesn't have so many worries, and he doesn't have to worry about being surrounded by fierce beasts if he speeds up directly.
Xiang Nan immediately speeded up, turning into a beam of light and heading north.
Now he wished that some ferocious beasts would find him and come over to besiege him. It would be better if there were as many beasts as possible to be happier.
And the golden-blooded beast "Xiao Chong" devotedly guarded Xiang Nan's side, acting as a guard at any time.
In fact, this little bug is not a guard, he or she is more like a puppet, he has no vitality, and all his actions are executed only under Xiang Nan's orders.
This pale green sky lasted for a long time before gradually disappearing.
At this time, half a day had passed, and Xiang Nan finally arrived in the north.
Sub-light speed and light speed flight can both be regarded as Xiang Nan's martial arts, which must be driven by light speed thunder or thunder.
And when not using this kind of martial skill, Xiang Nan's normal flight, the peak speed, is actually far less than the sub-light speed, after all, he is not a speed fighter.
And here, due to the long distance, Xiang Nan encountered a new environment again.
Just north of the small secret realm is a snowfield.
To be precise, it seemed like a sea that had been frozen, and the ground under his feet was not thick snow, but an ice cap formed after the liquid was frozen.
The biting cold wind, coupled with the heavy snow, made Xiang Nan feel icy all over, and couldn't help shivering.
"The temperature is unbelievably low." Xiang Nan breathed out on his hands and rubbed his face vigorously.
He is a martial artist at the seventh level of divine martial arts. With the physical fitness of a martial artist of this level, it stands to reason that any icy area in the world will not affect him in the slightest.
But the fact is that with his physical fitness, he felt very cold, and the temperature here was really astonishing.
"Huh..." Xiang Nan let out another long breath, and said, "If you are a martial artist in the Good Fortune Realm, once you come here, you will be frozen to death in an instant, right? You don't even have time to react."
Big Snake said: "The lowest temperature common in the material world is called absolute zero, which is about minus two hundred and seventy degrees."
"But the cold air here has far exceeded this, which is theoretically impossible to exceed the low temperature limit. I am afraid that the temperature here is at least below minus 10,000 degrees."
Xiang Nanqi said: "But how is this possible? Absolute zero is the lowest limit of low temperature, and it should not be broken."
He twirled a snowflake in his hand, and the snowflake was cold, and said: "The existence of matter must rely on energy and heat. Absolute zero is the lowest limit for matter to keep moving."
Big Snake said: "Yes, but that is compared to the world of ordinary people, and the temperature here has already entered the realm of law."
"The laws of nature have been broken here, or we can expand our imagination."
"You mean..." Xiang Nan said thoughtfully, "Maybe, the natural laws in this small secret realm are different from the natural laws in our world?"
Big Snake said: "Well, it's very possible."
Xiang Nan has nothing to say, if the rules are different, then everything is possible.
Human imagination is always imprisoned by known knowledge. With the continuous advancement of civilization, human beings continue to discover facts that were absolutely unbelievable, but actually exist.
Just like superluminal space.
The reason why human beings feel that there is absolutely nothing in this world that can exceed the speed of light is because the limit of detection means and perception ability is limited below the level of full speed of light.
Above the speed of light, there is a faster speed, but it cannot be proved or perceived, at least at this stage.
Xiang Nan walked on the vast ice sheet, constantly running exercises to speed up the circulation of the lightning force in his body, so as to provide enough heat for his body to keep him alive.
That's right, walking, not flying.
Because he found that under this damn super low temperature, the frequency of movement of everything was greatly reduced.
This includes the stellar energy of the warrior.
That means that if Xiang Nan wants to condense a normal sword glow, he will have to consume at least fifty times more than the normal temperature!
And flying here also consumes fifty times the thunder power consumed by normal flight.
But this is only the consumption factor for calculating the thunder force. In fact, the ultra-low temperature environment makes exercise itself extremely difficult.
He wanted to let himself float and fly, so the difficulty level increased by about a hundred times.
Counting the difficulty of flying and the consumption of flying, his current consumption of flying has reached an astonishing five thousand times.
This is disastrous for warriors.
"Huh... What a hellish place." Xiang Nan rubbed his face vigorously again.
His face was numb from the cold, and it was already difficult to express himself.
Big Snake said: "It's better to be careful, if you encounter an attack here, it will be really troublesome."
Xiang Nan was convinced.
But, whatever you are afraid of will come.
Xiang Nan stopped in his tracks, squinted his eyes slightly, and looked into the distance. I saw something sitting on the ice sheet directly in front of me, which looked like a snowman from a distance.
