Everyone suddenly realized when they heard that the earth element core crystal of the earth spirit beast originally came from the underground king.
No wonder the earth spirit beast was originally a human-earth beast, but now its form is completely different from that of a human-earth beast. It turned out to have been transformed by the Underground King.
"So, this underground king is still a kind man." Lan Fengyuan joked, after all, if he had obtained the earth element core crystal, he would naturally not give the element core crystal to a monster like this.
"I'm afraid it's not that simple..." Dragon Phoenix Beast's heart moved and he pondered.
Because when he was in the "Wild Desert", Lin Yun discovered that the number of "immortal storage beasts" released by the earth spirit beasts was very large. The immortal energy and life breath collected in one day alone were enough to provide a large number of lives.
body.
And such a majestic immortal energy and life breath cannot be absorbed by the earth spirit beast alone.
So there is only one possibility!
The "immortal storage beast" released by the earth spirit beast, the collected immortal energy and life breath are actually all supplied to this underground world.
This is why, when Lan Fengyuan asked why the underground world could still maintain a population of billions after millions of years, the dragon and phoenix beasts thought it was the earth spirit beast.
Dragon Phoenix Beast expressed his thoughts, Lin Yun slowly shook his head and said: "You are only half right."
half?
Everyone stared at each other with big eyes and small eyes, and finally their eyes fell on Lin Yun, waiting for Lin Yun's explanation.
Lin Yun said in a deep voice: "Actually, the immortal energy and life breath collected by the earth spirit beasts are not provided to the entire underground world, but to the underground army led by the underground king."
"Because they are exposed to the radiation of the earth's core energy all year round, the lifespan of the underground people is not long. However, with the life breath and fairy energy collected by the earth spirit beasts, at least the life span of the underground people under the command of the underground king can be increased to a certain extent.
"
"After that, the Underground King allowed these underground people whose lifespans to be extended to be used as "breeding pigs" to reproduce in large numbers."
Everyone was dumbfounded. If it was true as Lin Yun said, then the word "breeding pig" was indeed the most appropriate word to describe it.
After all, there are men and women in the underground world, and I'm afraid the underground people's reproductive methods are no different from humans.
Because the lifespan has been increased, they can continue to reproduce for a long time. This is also the reason why the underground world can still maintain a population of billions.
At this moment, Lin Yun suddenly said: "But I think that reproducing offspring is not the real purpose of the Underground King."
Everyone fell silent, and Lin Yun continued: "These underground people who have received the immortal energy and the breath of life, together with the next generation they gave birth to, will adapt to the intensity of the immortal energy and the unique breath of life on the ground in advance.
"
"If my guess is correct, the Underground King is no longer willing to continue living in this underground world, and he wants to return to the surface world."
Lin Yun's guess made everyone gasp slightly.
"Does he want to start a war with humans on the ground?" The biological doctor who rarely spoke could not help but exclaimed.
Lin Yun nodded. Apart from this, he could not think of any other reason.
And judging from the memory of this underground man, this underground king who is half a step into the Martial Emperor realm is by no means a kind person. He is ruthless and has caused dissatisfaction among many underground people.
The ruins they are now in were inhabited by a large number of underground people, but those underground people were all massacred because they resisted the rule of the Underground King.
Having discovered a brand new world and being able to capture the earth spirit beast made everyone extremely excited.
But now that Lin Yun's words came out, everyone felt extremely heavy.
"Lin Yun, can we catch the earth spirit beast yet?" Lan Fengyuan wanted to back down. After all, whether he could catch the earth spirit beast or not actually didn't mean much to him.
And the Underground King is half as strong as the Martial Emperor, so they have no chance at all.
Lin Yun thought for a long time and was ready to give up this opportunity.
Because his current strength is simply not enough to challenge the Half-Step Martial Emperor.
What's more, in this entire underground world, there are not a few underground people with the strength of Wu Zun.
It can be said that today's underground world is not like a force, but like an entire world.
Lin Yun will consider the pros and cons. Although the earth element core crystal is necessary, it does not have to be obtained now.
Under the protection of the Underground King, the earth spirit beasts will not have any big problems. As long as their strength grows to a certain level in the future, they can come back and take away the earth element core crystal.
"In that case, let's go back first. It's not suitable to stay here for a long time." Lin Yun quickly made a decision. Since he had decided not to get entangled here, he would leave as soon as possible.
Just when everyone was about to leave, Lan Fengyuan stopped. He wanted to take the underground man back for research.
Lin Yun told him bluntly: "It's not necessary. The so-called survival of the fittest, the reason why they can absorb the energy of the earth's core is purely because they have lived here long enough and need to survive, which is the result of evolution and mutation."
"I have just used my spiritual sense to detect them. Their body structures are not much different from humans, and they have no research value."
Since Lin Yun's words have reached this point, Lan Fengyuan no longer insists.
Everyone immediately set off to the entrance they had just entered.
"Since you have no value, then die." When Lan Fengyuan left, he penetrated the underground man's heart.
About when everyone was flying ten thousand meters ahead, suddenly, the yellow sand in front of everyone, like a huge wave, hit Lin Yun and the four of them head-on.
The incident happened suddenly, and the yellow sand was so powerful that it rolled up thousands of feet high. For a while, no one could dodge.
Lan Fengyuan was closer to the biology doctor and immediately grabbed his shoulders and flew higher. Lin Yun also immediately took off.
"It's amazing...what is this?" Lan Fengyuan was stunned, looking at the desert below his feet, which was now a hundred miles in radius, as if a huge desert wave had rolled up.
Layer after layer of sand waves swept past, and the scene was very spectacular.
This sand wave did not last long. It came and went just as quickly. It only lasted a few seconds and was extremely fast.
Gradually, the land returned to calm, but now the ground has undergone earth-shaking changes.
"Oh my god...that...what is that?" The biology doctor was shocked.
Lin Yun and Lan Fengyuan also looked in the direction he was looking.
