Han Yu didn't know whether to be happy or disappointed.

This so-called seven-colored mixed yuan Xuandan is even praised by the master, it must be a superb treasure! But after all, it is someone else's thing, if you take it, it will become a thief.

"Stupid apprentice, this thing is very useful for teachers, so ...... Gotta take it!"

"Keke, what should I do if someone from the Yannan Sect finds out?" Han Yu frowned and said, this lack of virtue makes it really impossible for Han Yu to do it.

"I don't think the people of the Yannan Sect have discovered this thing either, otherwise they wouldn't have been able to put such a precious thing in broad daylight! But they should have guessed that the energy of this spiritual spring has a source, but they just can't find out!" Yang Tianfeng said: "So, we can change the 'source' for this spiritual spring."

"What kind of seven-color mixed yuan Xuandan, is there anything that can replace it?" Han Yu said in surprise.

"Go down and you'll know!" As he spoke, Yang Tianfeng looked at the spiritual spring that exuded seven-colored brilliance again, and there was an inexplicable deep meaning in his eyes.

......

Han Yu jumped into the pool only to find that the energy in this spring water was so thick and pure, and he couldn't even absorb it!

However, Han Yu was not busy absorbing the energy here, but swam towards the depths of the pool, which seemed to be small in size, but the depth could be described as bottomless. By operating the internal force, the surrounding energy is slowly converted into its own use, and there is no need to worry about insufficient energy supply due to lack of oxygen.

"Boy, you have to be careful, the further down this spiritual spring, the stronger the energy will be, and the pressure on you will increase!" Yang Tianfeng said.

"So what to do?" Han Yu frowned and asked.

"You go to the space cage, and when I'm done, I'll let you out!"

"Oh!"

Immediately, Yang Tianfeng swiped his hand, and the surrounding space cracked, Han Yu didn't say much, he got in, and after entering, Han Yu could still clearly see the scene outside.

"Ready, it's time to speed up for the teacher!" Yang Tianfeng paused and shot towards the bottom of the pool.

......

Han Yu didn't expect that this seemingly small spiritual spring would be so deep, hundreds of meters deep.

According to Han Yu's estimation of the distance, this place was close to about two hundred meters from the ground, and the spring water had turned into seven colors, and the energy there was so strong that it could almost be seen with the naked eye.

"Dao" Yang Tianfeng slowly stopped his figure and said.

Han Yu looked around, almost all of them were springs emitting colorful light, but directly below, there was a layer of seven-colored light curtain.

"Under this light curtain, there is the seven-color mixed Yuan Xuandan, and this light curtain can only be broken by reaching at least eight turns of the beast venerable. ”

"Oh!" Han Yu said thoughtfully.

"It's a pity that this light curtain can't help me!"

As a faint smile appeared on the corner of his mouth, blue flames appeared on Yang Tianfeng's body, and after a while, he disappeared into the air.

When he reappeared, Han Yu found that he was in a stone chamber, and directly above it was a water curtain, as if he could not enter the stone chamber for some reason.

"It's ...... Cultivating Spiritual Grass!"

Han Yuhao didn't look closely, but he heard Yang Tianfeng's surprised voice.

Follow the prestige, only to see a stone platform in the center of the stone room, there is a thin layer of soil on the stone platform, and nine grasses of different colors are planted on the soil.

"What is the Soul Cultivation Divine Grass?" Han Yu asked

"Cultivating the Spiritual Divine Grass, the Cultivating Spiritual Wisdom Grass! No wonder there is such a seven-colored mixed Yuan Xuandan at this time!" Yang Tianfeng touched his chin and said: "The Spiritual Cultivation Divine Grass, the Nine-Colored Divine Grass, is born together, grows together, one less plant, one more plant is not good, this stone platform is like a radar that slowly pulls together the surrounding thousands of miles of heaven and earth energy, and this Spiritual Cultivation Divine Grass gathers these energies, so it can form such a spiritual pool!" As he spoke, he looked up.

"Although the energy of this spiritual spring is strong, it is less than one percent of the radius of thousands of miles, and the rest of the energy can form these medicinal materials around it, as well as ...... It's this Colorful Mixed Yuan Xuandan, the masterpiece of the Spiritual Cultivation Divine Grass!"

"After the divine grass is together, it will be able to bloom in a year, and then bear fruit in turn, mature one plant, this seven-color mixed yuan Xuandan can produce one more color, and the energy will be more than ten times more, and now this seven-color mixed yuan Xuandan, at least it can make a human emperor peak powerhouse, impact the earth emperor, it already has the energy of the earth emperor. After all the nine divine herbs bear fruit, they will start to cultivate the spirit, and after the spirit is raised, it will be called the primordial divine pill, and this elixir may only be used by the emperor!"

"Then why don't you wait until it's finished to get your hands on it?" Han Yu asked.

"Stupid boy, it takes a thousand years for this Soul Cultivation Divine Grass to mature, and this Seven-Colored Mixed Yuan Xuandan may have been condensed for more than 7,000 years before it can be gathered like this! It will take another 2,000 years to wait for two to mature, and another thousand years to cultivate the Spirit, how can I have waited for so many thousand years!"

"Uh...... It's been so long......"

"Hmph, not contented fellow! The primordial elixir after the cultivation of the soul is spiritual, and can turn into a beast form, but it only has preliminary spiritual intelligence, but it will eat the spiritual fruit of the nine divine grasses and refine it, in that way, he will turn into a human form, and have the legendary immortal body, and no one can eat him!"

"Oh!" Han Yu nodded thoughtfully.

"Running into such a thing can only say that we are in luck!" Yang Tianfeng smiled, then stared at the seven-colored mixed yuan Xuandan for a few minutes, his mouth pursed, and his right arm, which was stained with dark blue flames, stretched out, and easily passed through the thin enchantment covering the Xuandan, grabbed the seven-color mixed yuan Xuandan inside and took it out, "This protective shield is too weak, any alien soul can break it, which brain-dead person will put this protective shield in this place!"

......

"Ah...... Ahh I don't know where, a girl in black sneezed.

"Who's scolding me?" The woman wiped her nose and said indignantly, listening to the voice, it was just a seven or eight-year-old girl!

"Could it be that there is something wrong there, no, we have to go and see!"

As he spoke, he disappeared into thin air.

......

"Now that the things are in hand, boy, you can go here to cultivate!" As he spoke, Yang Tianfeng waved his hand, and the space cracked, and Han Yu fell out of it.

"Huh, won't you be overwhelmed by energy?" Han Yu exclaimed.

"Stupid, the energy above is combined with the spring water, and spontaneous combustion will also produce a huge energy pressure, although the energy here is strong, but it is free of the air, and it will not produce energy pressure!"

"Oh!" Han Yu scratched his head and looked around the stone room, there were a lot of medicinal herbs, Ganoderma lucidum or something, and the energy in the air was really very strong.

"Refining little by little, don't be in a hurry, otherwise it will blow you up!"

"Understood", as he spoke, Han Yu sat on the spot, operating the internal force to form a cyclone, slowly integrating the surrounding energy, and then introducing it into the body, running in the body, and transforming it into his own internal force.

"The energy here is the incomparably pure energy between heaven and earth, and it is still full of aura, I believe it can fill that gap for you!" Yang Tianfeng muttered.

After Han Yu controlled the energy for a few turns, he was pleasantly surprised to find that part of the energy in his body turned into seven-colored streamers, flowing towards the Inner Dan, and then the little bit of emptiness in the Inner Dan was slowly disappearing.

"This certainly has the function of stabilizing Neidan!" Han Yu felt a burst of joy in his heart, the rich energy here made him much faster than the energy fruit speed of ordinary cultivators, according to this progress, it would not take him three days to be able to advance from the original alien spirit to an official one-star alien spirit, compared to others, this speed was already quite good.

Looking on the Internet, Han Leopard, who is in the spiritual spring, is also desperately absorbing the energy of the spiritual spring, and this energy seems to be inexhaustible, constantly flowing into Han Leopard's body.

...... Three days later......

The eyes were shining, and the place of the spiritual spring was much more lively than before, Lin Fei and Qin Xia were staying quietly next to the spiritual spring, they knew that Han Yu and Han Leopard were going to come out today.

Deep in the Spiritual Spring.

Han Yu sat cross-legged on the ground without moving, but his spirit did not relax to observe the situation in his body.

In the past three days, the colorful energy not only replenished his inner pill little by little, making it mixed and full, but also brushed some of the meridian pulses in Han Yu's body and became more tenacious. With the continuous supply of energy, the body tirelessly refined it, and then poured it into the inner pill, the volume of the inner pill became larger and larger, and Han Yu understood that when it was big to a certain extent, it was the condition to advance to a one-star alien spirit.

I don't know how long it took, but Nedan suddenly shot out a white brilliance. The surrounding energy surged, forming a huge energy mass, the energy mass expanded, constantly absorbing the surrounding energy, and Han Yu hurriedly mobilized the energy in his body and poured it into it violently.

I don't know how much energy I absorbed, the energy suddenly stopped expanding, and began to slowly become smaller, smaller, and finally, when it was small enough to a certain extent, it turned into a milky white pill the size of a dragon's eye, which was Han Yu's inner pill, which was more pure and white than the previous one.

"Wow! Finally made the cut!" Han Yu opened his eyes that had been closed and said with great joy.

"I'm so happy when I get to a one-star strange spirit! Yang Tianfeng on the side.

Han Yu ignored it and said, "It's been three days since I've been here, Master, you can go!"

"Just kidding, there are so many good things in this stone room, don't you plan to fish some and go!"

"Good stuff?" Han Yu looked at the stone platform again.

On the stone platform, seven ripe grasses hang seven heavy fruits, which are particularly attractive.
