It turned out that Liu Feng's worries were unnecessary.

The busy people in the cave never cared about the low-grade Yuan Qi spars piled up on the open ground, and as for those people in Tianhu, they only glanced at it and didn't look closely. So even though it's almost a fifth, no one has noticed.

Liu Feng secretly breathed a sigh of relief and continued to start a new day's work. As for what Jin Ling did, he didn't ask, he believed that only when it was done, he would definitely tell himself as soon as possible.

Mining, especially this most primitive mining method, is the most boring and tedious. And, it's extremely slow.

"Huh?"

Liu Feng swung it out with a shovel, and suddenly his eyes lit up, a fist-sized spar was completely different from other places. It turned out to be a fiery red spar, completely different from the kind of white you usually see.

Liu Feng quietly glanced around, everyone was busy with their own things, and no one noticed him. At that moment, he quietly reached out and held it in his hand, and suddenly, a vast fluctuation of vitality passed from it.

It is dozens of times, or even hundreds of times, of ordinary Yuan Qi spars!

Top grade...... Vitality Crystal?

Liu Feng's eyes widened suddenly, although he didn't know why this spar was fiery red, the vitality fluctuations that could be revealed from it made him know very sure that this was definitely a high-grade spar.

This piece of high-grade spar is worth hundreds of low-grade vitality spars. The most important thing is that the quality of the vitality contained in this is also very different from that of the lower grade spars.

Although the valuable contrast between the two can be practical, anyone would rather choose the high-grade Yuan Qi Crystal.

"It's fire crystal. ”

Jin Ling's voice sounded in Liu Feng's heart, "This is not an ordinary spar, it contains the purest fire element, which is of great benefit to those who practice fire system exercises." This piece is definitely comparable to the value of hundreds of high-grade spars. ”

Hearing this, Liu Feng couldn't help but swallow his saliva, if this is the case. Then this piece of fire crystal can be exchanged for a superb vitality crystal.

"Oh my God! It's only the next day! Is my brother's luck so good?"

Liu Feng was ecstatic in his heart, blaming everything on his luck.

Jin Ling then said: "It's a pity that this is not of great use to you, and the value of immortal cultivators who are not using fire-based exercises is just a normal piece of high-grade spar." ”

Liu Feng understood this truth, the exercises of immortal cultivators were strange, but they were inseparable from the seven attributes of metal, wood, water, fire, earth, wind, and thunder. The martial arts to be cultivated are generally determined according to one's own exercises, and the exercises to be cultivated can generally be cultivated at the same time as long as they are not mutually restrained.

For example, the Qingxiao technique cultivated by Liu Feng belongs to the 'wind' attribute method, and the 'Spirit Ape Nine Turns' is also a method that is biased towards the 'wind' attribute.

These are all described by Li Lao in the jade slips he left behind, and Liu Feng also completely remembers them in his heart.

It's just that although things are good, there is nowhere to hide.

Liu Feng sighed secretly in his heart, if he put it on his body, he would definitely be felt by those people. After all, the primordial body can only hide its own cultivation. And you can't hide everything on your body so that people can't feel it, after all, this is a high-grade fire crystal!

As for the 'Tianyin' jade pendant, Liu Feng didn't even think about it. If you do that, you'll be completely hidden.

"Forget it, this girl will keep it for you. ”

Jin Ling's voice was a little dissatisfied, this kind of high-grade fire crystal was worthless in her eyes. However, who made the people she relied on so low now?

"Can you keep it?"

Liu Feng was surprised, although the golden bell was peculiar, there was no place to store things.

Jin Lingjiao said angrily: "Of course, you really think that this girl is the same as you? ”

"What?"

"Celestial jade bottle. ”

"Tianlong jade bottle?" Liu Feng was stunned for a moment, and then remembered that Tianlong jade itself is an important material for refining utensils, and the Tianlong jade bottle made of it, Jin Ling once said that it can be filled with mountains and seas. But as for how to use it, Jin Ling only told him that his strength was not enough to refin.

After the words fell, Liu Feng glanced around and quietly took the Tianlong jade bottle in his hand.

The golden bell quietly appeared in Liu Feng's hand, and a cold aura instantly wrapped around the Tianlong Jade Bottle like a gossamer, and at the same time, it also wrapped around the fire crystal, and completely disappeared in the blink of an eye.

In this way, the thing is definitely your own.

Liu Feng couldn't help but feel a burst of joy in his heart, Luo Xianmen wanted to be a coolie, but where would he have thought that he didn't have much to mine, but what he 'embezzled' was something they couldn't even think of.

However, the rest of the game was not so lucky. I don't know if it's because this 'fire crystal' is too unique, for nearly half a day, Liu Feng didn't even see a piece of low-grade Yuan Qi crystal.

It's time to end again, Liu Feng dragged his tired body out, according to Liu Feng's estimate, the No. 10 Yongdao where he was located was almost two thousand meters deep.

Of course, Liu Feng's 'tired' state is also completely faked. There is a true element surging in the body, coupled with the self-improvement of the 'origin of life', it is difficult to get tired!

However, in this environment, you have to pretend to be something.

It was night, and the cave was quieter than yesterday. The new group of people is even more tired, and the true element in their bodies is even more depleted.

Although the air of the 'Burial Wasteland' is difficult for these people with a foundation in cultivating immortals to survive, what is even more terrifying is the night, the night is simply above the sword. But fortunately, these people are very obedient and will not walk out of the cave without permission.

Until there was no movement in the cave, the golden bell quietly appeared outside as yesterday. And Liu Feng also began to absorb the vitality that existed in the Yuan Qi Crystal.

Cycle after cycle, time passed quietly, and soon half a month had passed.

In the past half a month, every day Liu Feng did not have a break to absorb the vitality in the spar. However, the amount of absorption will be deliberately reduced each time. This is also to avoid being discovered by Tian Hu and others, after all, these people are not stupid.

However, even so, it made Tian Hu and others helpless. You must know that on the first day of Liu Feng's arrival, there were thousands of Yuan Qi Crystals in the cave. But half a month later, it was only less than 5,000 yuan. On average, less than 300 yuan is produced in a day. Although Tian Hu and the others had a lot of questions in their hearts, fortunately, in the past half a month, there were nearly 1,000 intermediate Yuan Qi spars, 100 high-grade Yuan Qi spars, and a superb spar.

As for Liu Feng, except for digging a fire spar on the first day, there was no big harvest at other times.

And this night, according to his usual habits, Liu Feng absorbed a burst of vitality in the Yuan Qi Crystal. Suddenly, the true element in his body was boiling, as if it was about to explode.

You must know that before this, Liu Feng had already reached the late stage of cultivation in the Transcendent Realm.

And after half a month of using the Yuan Qi Crystal, his strength has already reached the peak of the late stage of the Transcendent Realm!

If it is changed to ordinary cultivation, even if the exercises are peculiar, it will take at least half a year for Liu Feng to reach the current level. But now, it has been done in half a month.

That's the benefit of having 'resources', which is ten times faster.

It's just that if the current Liu Feng doesn't break through the realm quickly, he will no longer be able to continue to absorb the vitality in these low-grade spars. In other words, it is useless to wash it, the body is already completely saturated.

Although Jin Ling was amazed at Liu Feng's growth rate, she didn't say it, after all, according to her calculations, if Liu Feng wanted to impact the Dao realm, it would take at least a month. However, it turned out to be half the time earlier than she thought.

Liu Feng also understood his situation at the moment, but on the night of the 'Burial Wasteland', even if he was now, it would be difficult to stay in it for a quarter of an hour.

However, this question is not difficult because there is a golden bell!

The mystery of Jin Ling, Liu Feng will definitely not be able to figure it out in a short period of time.

Night, moonless, the wind howling.

At night in the Funeral Wasteland, there was a deathly silence in the frenzied wind.

The golden bell was suspended above Liu Feng's head, and with her protection, Liu Feng would not be harmed in the slightest.

It wasn't until a mountain col five kilometers away from the cave that Liu Feng stopped, this distance was far enough that he didn't have to worry about his situation being discovered.

Liu Feng chose a relatively flat ground and sat down, and the matter on the jade slip about the impact of the Dao realm came to his mind again.

The realm of enlightenment is not the true enlightenment. It's just that the immortal cultivator has groped for a trace of the rules of heaven and earth, that is, the way of heaven, and imprinted a trace of his soul in heaven and earth.

So, although it is a preaching, it is actually enlightenment.

Liu Feng sat upright, recalling his own past and going experiences, Li Lao's death, and everything that happened to him afterwards. As these thoughts passed by one by one, Liu Feng's state of mind was surprisingly calm.

Under Liu Feng's mind, Zhenyuan slowly filled every meridian in his body.

A blue-green true yuan completely enveloped Liu Feng, and Jin Ling guarded it quietly, without saying a word. This kind of thing can only be done on your own.

Unless, there can be someone like Li Yuansu and Li Lao, who can arrange a 'Yuan Capture Enlightenment Dao Array' to forcibly pass on his understanding to Liu Feng. It's just that, in that case, the way of enlightenment is not one's own way, but the way of arranging the formation law.

The true element is constantly compressed, constantly impacting the meridians, and becoming more and more refined.

Liu Feng completely let go of his perception, and his spiritual power rushed out of the protection range of the golden bell without reservation, to feel the power of heaven and earth.

Suddenly, endless ferocious, manic, and bloodthirsty thoughts invaded Liu Feng's divine consciousness from all directions.

"Humph!"

Liu Feng snorted, his face slightly pale. But he still didn't stop, and his spiritual power covered all the places around Baizhang Fang Yuan with the largest scope.

And at this moment, all the scenes of heaven and earth are displayed in Liu Feng's mind, not in the state that he usually sees with the naked eye. It is a kind of wonderful texture, there are flowers and trees, there are birds and animals, and there are thousands of human beings, as if the whole world is made up of these 'wonderful textures'.

These wonderful textures have an ancient, desolate, immutable atmosphere. There is also a strong, coercive power that cannot be expressed in words.

This is the way of heaven.
