Finally found a public restroom, and the two escaped in a hurry.

"Hurry up and take me to stealth together!" Zhang Yunxian felt that his body was a little weak after crossing over just now, and after taking a closer look, he was almost fainted directly.

"Why don't I have any spiritual power and essence left......

Even the hidden magic power can't be used, so he can only ask Xingzhen to take him with him.

With a wave of Xingzhen's sleeves, the two of them appeared at the entrance to the secret realm at the bottom of the river.

Zhang Yunxian couldn't help himself with grief in his heart, the strength he had worked hard to accumulate for most of the year was actually consumed like this, to be honest, he had an urge not to live.

"Good thing I still have meteorites!"

At the end, Zhang Yunxian gave Xing Zhen an order, if there was a suspicious person nearby, he would detain it first, and then he entered the crazy cultivation mode.

With his current realm, the speed at which he absorbed a meteorite was only a few breaths, and he simply took out a hundred and ten pieces at once, arranged them in a circle around himself, and guided the barely visible essence in his body to run slowly.

More than a hundred meteorites, although they look different in size and uneven appearance, but the essence energy contained in them together is quite terrifying, especially under the deliberate control of Xingzhen, these energies cannot be dispersed by a foot from Zhang Yunxian's body, this high-intensity compression makes these energies almost become a white fog visible to the naked eye, completely submerging Zhang Yunxian's body sitting at the bottom of the river.

It's just that in the space where he is, all the river water actually makes a half-boiling 'gurgling' sound, fortunately, Xingzhen took action to suppress it, otherwise this boiling trend is afraid that it will spread directly from the bottom of the river to the surface of the river, but I am afraid that it will cause a group riot at that time.

This boiling scene lasted for about three or four hours before it gradually subsided.

The essence energy, which was like substance, also began to contract and tighten at an extremely fast speed, as if something was devouring them.

Zhang Yunxian's figure gradually re-revealed, only to see that his face was ruddy, his breath was long, and every time he swallowed, a large amount of turbidity was discharged, and the essence energy turned into those meteorites quickly flowed into his body along every pore on his body.

"Click!"

Zhang Yunxian was shocked, he felt as if something in his body had been broken, and the endless flow of essence traveled domineeringly along each of his capillaries, and where he passed, the blood in the blood vessels seemed to have been rebaptized and purified, and then countless black blood beads gradually seeped out from his skin from the inside out, and then mixed into the turbid river water, which actually dyed the river water within a radius of a few feet of him red.

"What's the situation? Is it impossible to explode and die?" Zhang Yunxian opened his eyes, and when he saw the scene in front of him, he himself was taken aback.

The essence in his body was still wandering freely, and everywhere he passed, his blood flowed with a faint golden color, and Xingzhen on the side was overjoyed.

"My lord, you actually evolved ahead of time?"

"Evolution?" Zhang Yun blinked inexplicably.

Generally speaking, the vision of flesh and blood evolution will only occur after a cultivator enters the realm of a real person, and the Hong Yuan you faced just now is a real person who has undergone a second evolution, but now you have just broken through to the middle level of the Sage, this kind of evolution has happened, it is really incredible!"

Looking at Xing Zhen's overflowing excitement, Zhang Yun asked ignorantly: "Is this...... What's the use of evolution?"

"Of course it's useful!" Xing Zhen inadvertently pressed his palm, and the little essence energy left drilled into Zhang Yunxian's body, and he swam along his veins for two more rounds before finally dormant and dissipated in every inch of his muscles.

"My lord, do you know what the ultimate goal of my generation of cultivators is?"

Xingzhen's question made Zhang Yunxian stunned: "The ultimate goal? My understanding should be to continuously improve the dimension of our life, so that we can see the truth of life and the universe more clearly!"

Xing Zhen nodded: "My lord, what you said has some truth! But what I'm talking about is a goal in a narrow sense, in the cognition of the vast majority of cultivators, it is to continuously improve their cultivation, to be able to enter the sainthood from the sage, and then to be able to transform from the sage, and the real person is looking forward to breaking through the barriers of the true realm and being able to ascend to the 'realm of heaven and man'...... Everyone is constantly pursuing more powerful power and longer lifespan, but few people seem to seriously think about what kind of existence is celestial beings?"

What kind of beings are celestials?

Thanks to Shenyi's earnest teachings, Zhang Yunxian still understands a little.

"Isn't it the last group of life races created by the Protoss that are most similar to them?"

Xing Zhen nodded: "That's right! Celestial beings are indeed the closest existence to the Protoss, and they are also the ultimate form that human beings can achieve through cultivation......!"

Speaking of this, Xing Zhen paused for a moment, and Zhang Yunxian glanced at him suspiciously.

"But not all cultivators are able to achieve this ultimate form!

"As you said, only after a cultivator reaches the real human realm can he meet the conditions for starting evolution?"

"Yes, my lord! Only by becoming a real person, and the body functions have been nourished by the essence and qi and are strong enough, can we withstand the 'devastation' of evolution! And only after more than three thorough evolutions can we impact the path of heaven and man!"

"What exactly is evolution?"

"Everything! the body's shell, flesh, muscles, bones, internal organs...... And the first and easiest thing to start evolving is blood!"

Zhang Yunxian: "...... Can you make it easier to understand?"

Xingzhen thought for a moment and explained: "When the genes of our new humans were created, some of the key contents were removed! And this key part is the difference between us and the celestials, and it is also the part that we want to accomplish through evolution!"

Zhang Yunxian instantly understood a little, Shen Yi also said that the purpose of the Protoss to create the new human race is to exile and consume the spiritual power of the Spirit Race, in order to ensure the absolute loyalty of the new human race to the Protoss, and never betray such a thing as betrayal, they erased important genetic information such as 'endless lifespan' and 'power to destroy the world' in the genes of the new human race.

Xingzhen means that after a cultivator reaches the realm of a real person, there will be a chance that there will be the possibility of evolution, and after two or three so-called 'evolutions', the genes of human beings will be raised to the same level as those of heaven and man!

"Flesh and blood, muscles and bones, internal organs...... Zhang Yunxian said silently, "Shen Yi did say that in order to let humans spend most of their energy on survival, the Protoss added the same diet and digestive system as the animals......

"Yes, and the survival system of the celestials is completely different from ours! They don't need to eat or drink, nor do they need to temper their bodies through high-intensity exercise, they only need to exhale to sustain their lives and survive indefinitely!"

"In other words, the gap between human beings and celestial beings is not only dependent on the improvement of cultivation, but also must be completed through evolution in order to cross the past?"

Xingzhen: "Yes, my lord, that's the case! Take me as an example, I've been wandering at the peak of the real person for more than 300 years, but the heart lacks the last evolution, and I have never been able to take this step......

Zhang Yunxian suddenly realized: "I see! All these parts you mentioned just now have to go through three evolutions before they can be?"

"Yes!"

"Then this blood evolution that I have now will have any beneficial effect on me?"

"Uh...... Generally speaking, in the same realm, the real person who has evolved more times, the strength of his body, and his combat ability will be far better than that of other real people who have evolved less......! I can't say this situation well, I've never seen it before!"

Zhang Yunxian stretched out his right index finger, bit it hard, and squeezed out a few drops of blood with pale golden floating spots: "It seems that except for a little change in color, there is no difference in others?"

Xingzhen's eyes widened suddenly: "Golden blood......? What's going on?"

Zhang Yunxian: "Is there anything wrong?"

"No! It's just that, as far as I know, the direction of the evolution of real people's blood is changing towards silver!" As he spoke, he quickly blurred his fingertips, and suddenly white shiny silver blood droplets jumped into his fingertips, and Zhang Yunxian was also stunned when he saw it.

"Silver, is it because I'm the Apocalypse?

Xingzhen held his forehead: "I guess only this reason can make sense!"

Zhang Yunxian felt the essence in his body, and it became surging again, and because of this breakthrough, he actually stepped into the middle level of the Sage in one fell swoop, which can be regarded as a blessing in disguise.

The essence is replenished, what should the spiritual power do?

After looking inwardly at the two thin and humanoid spirits in his spiritual platform, Zhang Yunxian couldn't help but feel worried again.

"By the way! Maybe you should ask Meng Po! She's from the underworld! I wonder if there is a way to quickly increase her spiritual power?"

Zhang Yunxian is purely thinking about it, if Meng Po had a secret method to restore his spiritual power, when he was in the underground of Pengze Lake, he would have already restored his damaged spiritual consciousness completely, and there was still a need to suffer from his many tortures?

However, thinking of Meng Po, Zhang Yunxian suddenly remembered the whereabouts of the Protoss, and couldn't help but ask Xingzhen curiously: "You have traveled in the universe for so many years, have you found a place for the Protoss to live, and are they all still living on the moon now?"

"Alas......" I didn't expect Xingzhen to sigh when he heard this, and the self-blame on his face was overflowing: "Protoss...... Gone!"
