The reason why Wu Zhongyuan has no confidence is because the most difficult thing to determine is the difference in time, you must know that time difference and time are two completely different concepts, especially when it comes to the time difference between two time and space, which is almost traceless.

Calm his mind and feel it, he had sensed the broken tail of the demon king Mo Qi and the red poisonous snake before, and like them, the corpses of these demon monsters also had a strong tyrannical and murderous aura, which was also the common feature of demon monsters.

The demon is a change of the Yin genus of the beast race, most of the demons are the remnants of the beast after the death of the original god possessed by other beasts mutated, because only human beings have three souls and seven spirits, so most of the original gods after the death of the beast race are incomplete, and they retain more of the beast and attack instinct, which is also the reason why the demon monsters are tyrannical and murderous.

Two of these four corpses came from the other side of the enchantment, and they were all creatures from another world, and their original forms should not be what they are now, and the reason why they were hideous and terrifying was because they were possessed by the original god with demonic energy and mutated.

The other two corpses are from the world where everyone lives, and the host was originally a creature of this world, and it also mutated after being possessed by demons.

What is mutation, simply put, mutation is that it has changed differently than before, and mutated things are not representative.

Seeing that Wu Zhongyuan had been frowning, Wu Di asked in a low voice, "How is it?"

Wu Zhongyuan said, "These aliens are all possessed and demonized by the demons, and it is difficult to determine how long they have survived, and it is impossible to determine how long they have lived, so it is impossible to compare." ”

"Dongguan Qinglong is still here, can you ask it for advice?" Wu Di asked.

"I really can't do it, I can only ......," Wu Zhongyuan said this, and suddenly remembered something, and sensed the broken tail of Mo Qi and the corpse of the red poisonous snake from under the gravel not far away.

There were many strong winds and sandstorms in the desert, and the two things that had been sent before had been buried by the sand, Wu Zhongyuan found and grabbed the body of the half-truncated tail and the red poisonous snake from under the sand.

Wu Di was puzzled and looked at him suspiciously.

Wu Zhongyuan said, "Trees have growth rings, nails have year patterns, and the age of turtles and snakes will be reflected in the nails and scales. ”

As Wu Zhongyuan spoke, he took out a piece of snake scales from the corpse of the red poisonous snake, the snake scales were the size of a palm, and if he looked closely, there were really extremely fine lines on it.

The lines on the snake scales are in the shape of water waves, extremely fine, and if you change it to an ordinary person, let alone count, you can't even see it clearly, but Wu Zhongyuan's senses at this time are far beyond the scope of normal human beings, and after looking at it for a while, he came up with an approximate number, and there are about more than seven thousand water wave lines.

The scales of the snake with Mo Qi's broken tail are much smaller than the snake scales of the red poisonous snake, take one piece, and use the aura to swell to the size of the bowl, and then count, more than nine thousand.

Wu Zhongyuan studied liberal arts, and numbers were not his strong point, so he told Wu Di about his discovery, "Judging from the scales, Mo Qi has lived for more than 9,000 years, and this red poisonous snake is the general of the Three Spirits under his command, and he has lived for about 7,000 years." ”

Wu Di also knew that Wu Zhongyuan told him that these were for her to help calculate, "They have been imprisoned for five thousand years, and these five thousand years can be deducted." ”

"It can't be counted like that, because we don't know how long a year in the Atlas is here. Wu Zhongyuan shook his head.

"No, no, no, no matter how long the year in the Otherworld is us, they are in the Otherworld, they will follow the time of the otherworld, they will stay in the otherworld for a year, and there will be an extra line on the scale armor. Wu Di corrected him.

"Makes sense. Wu Zhongyuan nodded.

Wu Di said, "After deducting these five thousand years, the Demon King had four thousand years of Taoism when he was sealed, and the generals under his command had two thousand years of Taoism, and the time of their survival was also commensurate with the cultivation they had. ”

"I've always felt that this calculation is not very thorough. Wu Zhongyuan tilted his head in thought.

"It's not very meticulous, but the truth is right," Wu Di said, "they will definitely be deducted from the five thousand years they have been trapped in the other world." ”

"These five thousand years are for us, and maybe not for the Atlas. Wu Zhongyuan said.

"Think of it this way, we don't deduct five thousand years, but five thousand stripes on their scales. Wu Di said.

Wu Zhongyuan raised his hand and scratched his head, having a high Xuan cultivation is equivalent to having a super sense and extremely fast reaction speed, but it does not mean that he has become a genius, he is not good at anything, no matter how high his cultivation is, he is still not good at anything.

Wu Di smiled and said, "If our year is two years in the other world, then in the five thousand years we have here, there should be ten thousand more stripes on them." ”

"Yes. Wu Zhongyuan nodded.

Wu Di said again, "During the Great War of the Flood Famine, they already had three elements and three spiritual cultivators, and if they wanted to practice this kind of Taoism, they had to live for thousands of years. ”

"Hmm. Wu Zhongyuan nodded again.

Wu Di said again, "According to the existing clues, the other world where the demon clan is located is roughly the same as our time, and there are two other possibilities, one is that our year is their two years, this possibility can almost be ruled out, because the year patterns on the scales do not match, take a step back and say that even so, this situation is also beneficial to us, and the result is nothing more than an expedition of ten days, and five days to return." There is also a possibility that our two years are their year, which can also be ruled out, because the year lines are not right, and if this is the case, their year lines are much more than that. ”

Wu Zhongyuan didn't answer immediately, he was thinking about whether Wu Di was saying the opposite.

"The concubine's statement of one year and two years is just an expression of the speed of time, not an accurate inference. Wu Di added.

"What you say makes sense," Wu Zhongyuan reacted, "I'm not afraid that we will be in the other world for two years in one year, nor will I be afraid of us in the other world for two years and one year, I'm only afraid of us for one year, one day in the other world, if that's the case, then I will become the boss of the young and the young, I am still a teenager, and you have become an old woman." ”

"Judging from the year marks on the scales, the saint should be overly worried. Wu Di said with a smile.

Determined the most important time difference problem, Wu Zhongyuan dissected several other corpses, the stomachs of the two monsters living in the human world are creatures in the human world, and the monsters living in the other world are creatures in the other world, they don't seem to be picky eaters, their common feature is that the stomach is full, and the same is true of the corpses of those monsters dissected outside the weak water dragon Ze back then, it seems that they are all starving ghosts reincarnated, and they are all in a state of eating.

The corpse was stinking, even in the open desert, it also smelled bad, and after conducting the necessary tests, Wu Zhongyuan took Wu Di to teleport away and came to the collapsed demon clan's lair.

For the places where accidents have happened, Wu Zhongyuan likes to revisit the old place, and has checked many times, and is an enemy of him, if anyone has the idea that the most dangerous place is the safest place, I am afraid that he will die without a place to be buried.

Through the examination of the collapsed cave and the perception of the surrounding atmosphere, Wu Zhongyuan determined that the Demon King was not here.

After a short stay, Wu Zhongyuan teleported away with Wu Di again and appeared in Dongguan.

The eastern army camp had received a decree from the imperial court, and the defenders were divided into two, with the soldiers responsible for burying the corpses, while the warriors were packing up and preparing for the long journey.

Seeing the two coming, Yu Qingdu and Zhulang immediately led everyone to take over.

"Later, there will be wine and food delivered from the Drinking Horse River, and after a full meal, we will go to the north and south," Wu Zhongyuan said, "In addition, the two of you will lead the Purple Qi Warriors to stay here to accompany Qinglong until the last moment......
