Each crystal contains pure spiritual power, just like small pieces of spiritual stones, they are all condensed from the spiritual energy in the "Medicine" Garden, which shows how amazing the density of spiritual energy here is!

And the reason why these spiritual 'medicines' were able to survive was that Lin Feng also concluded that they had originally grown in the Thousand Cliffs Mountain, and might even have grown on the mountainside of this mountain, and the owner of the cave mansion discovered them, so he built the cave mansion according to local conditions, and directly built the 'medicine' garden where they grew up, making it a natural spiritual 'medicine' plantation, and only a few of the varieties were transplanted.

In any case, Lin Feng was full of great admiration for the initiative of the master of the cave mansion, and he deduced from the year of the elixir that this was an ancient monk site, and the two inscriptions left by this mysterious ancient monk made Lin Feng fall into a reverie, and he was stunned for half an hour before he came back to his senses and started to collect these elixirs.

Now that the spiritual 'medicine' has matured, directly transferring it to the Sumeru Illusion Ring can ensure that the 'medicine' and 'sex' are not lost, and more than a dozen spiritual 'medicines' have been harvested, Lin Feng has slightly modified the Spirit Gathering Array, and then used this 'medicine' garden as his own cultivation place!

After the room was cleaned up, Lin Feng flew out of the cave and began to arrange it in a big way, so that the defensive magic circle on the periphery of the mountain peak restored its original solidity, and a defensive magic circle was also erected on top of the cave, and then he returned to the 'medicine' garden to meditate with peace of mind.

A few days later, Lin Feng used the immortal net to decompose a large number of demon pills, ripened a sufficient number of Zhuji Dan main 'medicine', and then with the assistance of Taiyi Qianhua Ding, he began to refine Zhuji Dan!

Half a month later, the first furnace of Zhuji Dan was successfully practiced, and the Dan rate was only one percent. After the Void Spirit Base was built, Lin Feng's Void Spirit Power was several times stronger than before, and the Void Spirit Base was embedded in the Yuan Shen, with the help of the light of the Moon Kun Bead, the recovery speed of the Void Spirit Power had been significantly improved, which undoubtedly provided great help for refining the Zhuji Dan. (・)

A month later, the Tsukidan rate reached five percent, and three months later, the Tsukidan rate soared to ten percent, Lin Feng's technique became more and more proficient, and the refining of the Tsukidan had reached as many as three hundred!

Next, what Lin Feng refined was the Heart Nourishing Pill.

The purple condensation grass that Song Yunfang gave to Lin Feng at the beginning, during this time, under the nourishment of the Sumeru Illusion Ring, it had eased up from the malaise at that time, and under the urging of a large number of demon pills, the purple condensation grass quickly reached a state of ripeness, and then, Lin Feng took its seeds and the seeds of Youyang Fruit and Tianxiang Chrysanthemum, and successively matured dozens of spiritual "medicines".

The main "medicine" is ready, and the refining of the Heart Nourishing Pill really begins. In the first three months, there was no harvest, but in the fourth month, Lin Feng broke through the bottleneck of Danshu skills in one fell swoop and refined a furnace of Shuanglong Pill!

In order to refine the Heart Nourishing Pill, Lin Feng had no choice but to improve his Dan rate by refining the Zhuji Dan, but it was precisely because of this coincidence that he obtained more than 300 Zhuji Dan, so that he not only picked up a life in the later foundation building, but also completed the foundation building quality that others could not complete!

Using the immortal net to give birth to a piece of requiem wood, filling in the Shuanglong Heart Nourishing Pill, and then hiding it close to his chest, Lin Feng breathed a long sigh of relief, closed his eyes and meditated for three days and three nights, and his consciousness gradually entered the realm of selfless cultivation.

The next time was a difficult and long road to foundation building! And Lin Feng's foundation building could be described as a wonderful flower in the cultivation realm, with more than 300 foundation building pills in his hand, as well as hundreds of ninth-level demon pills in the immortal net, his foundation building quality reached an unprecedented supreme realm!

The first Tsukidan was swallowed, and the powerful "medicine" power quickly spread, and Lin Feng's dantian was surrounded by a thick "liquid" body, this "liquid" body was an extremely rich spiritual power essence, it had been transformed from a gaseous form into a drop of spiritual "liquid", tightly wrapping Lin Feng's primordial spirit. (・)

Under the effect of the "medicine" power of Zhuji Dan, Lin Feng quickly urged the immortal net to decompose the eight kinds of demon pills that belonged to "sex", and absorbed them into the Yuan Shen in equal proportions, the Yuan Shen grew rapidly, and the "medicine" power of the Zhuji Dan was covered with a solid shield around it, and the spiritual power from the immortal net would never be lost again.

However, just as Lin Feng was about to build the Yuan Foundation, there was an inexplicable change in the Void Spirit Base in the center of the Yuan Shen! The Void Spirit Sex Ball suddenly burst out with a powerful thrust, repelling the Yuan God that wrapped it around it, thus causing Lin Feng's Yuan Spirit to expand by as much as double in an instant, thus forming a void larger than the Yuan God with the Void Spirit Base in the middle!

Due to the existence of this void, a powerful spiritual pressure was formed between the Void Spirit Base and the Yuan Shen, Lin Feng was in unbearable pain under the pressure of the spiritual pressure, and in addition to the Yuan Shen, there was also the "liquid" spiritual power formed by the Zhuji Dan tightly wrapped, under the double spiritual pressure, his Yuan Shen was overwhelmed, and he was in danger of collapsing at any time!

What's even more amazing is that with the expansion of the Yuan Shen, the "liquid" spiritual power formed by Tsukidan is no longer enough to wrap it, and under the rejection of the Void Spirit Base, the Yuan Shen is continuing to expand outward with an irresistible trend, and once it breaks through the shackles of Tsukidan, it will face the end of being wiped out!

At the moment of life and death, Lin Feng quickly swallowed the second pill of Zhuji Dan, the "medicine" power was quickly dissolved, and the "liquid" spiritual power was wrapped around the Yuan Shen again, but because of this, the thrust emitted by the internal Void Spirit Base met resistance, and the spiritual pressure between the two suddenly increased, and the pain that Lin Feng was suffering suddenly rose!

In a certain space between Lin Feng's hands and feet, a huge hole was actually generated, and it felt as if some areas had collapsed, and a huge suction force came from this hole, and Lin Feng felt the spiritual power vacancy inside it from this suction!

Almost without any hesitation, Lin Feng urged the Devouring Technique of the Immortal Net, and a large amount of Demon Pill was decomposed into the source of spiritual power, surging wildly towards the void in the Immortal Net!

Then I felt that in the dantian, there seemed to be a heavy liliang gradually filling in, and the huge pressure formed between the void spirit base and the Zhuji Dan was suddenly relieved, but the density of the primordial spirit increased sharply, and the gaseous spiritual power was gradually condensing, becoming a trace of the "liquid" form, which was very similar to the "medicine" power of the peripheral Zhuji Dan!

It is precisely because of this change that the "medicine" power formed by the Tsukidan is getting weaker and weaker, and it can no longer stop the huge pressure formed by the gathering of the Yuan Shen, and the "medicine" power is then consumed sharply under the pressure of the Yuan Shen, and it will become thinner and lighter within a few breaths, and Lin Feng is fortunate to have saved a large amount of Tsukidan, relying on the number of Tsukidan to maintain this balance.

At the beginning, he swallowed a few grains in a row, and he could basically maintain this balance, but when the immortal net decomposed a large number of demon pills and injected them into the void in the primordial god, that position actually filled Lin Feng's primordial spirit and became a part of his primordial god!

In other words, Lin Feng's Yuan Shen had become huge in this short period of time, and his volume had already doubled! And the strange thing was that the part in the middle had formed a thick diaphragm between it and the Void Spirit Base, and this diaphragm was the Yuan Ji he had always dreamed of!

This Yuan Ji is no longer the Void Spirit Base that is "sexual" of the Void Spirit, but the Void Spirit Base that is different from it, but is closely combined!

Unlike all the monks' Yuan Spirit, Lin Feng's Yuan Shen has a Void Spirit Base in the center, and then there is a Void Spirit Base outside the Void Spirit Base, and outside the Void Spirit Base is the Yuan Shen, and outside of this Yuan Shen, like other monks, a real spirit base needs to be built!

In this way, Lin Feng's Yuan Shen seemed to be divided into three spheres, the most central ball was the Void Spirit Base, the middle ball was the Yuan Shen itself, and the outermost ball was the Solid Spirit Base that was about to be built. The three round balls are set together, and the real spirit base and the void spirit base are clearly distinguished, but at the same time, they are embedded with the primordial spirit, forming a powerful whole.

As a large number of demon pills were decomposed, the vast origin spiritual power was injected into the dantian, and the void in the primordial spirit had been filled with pure spiritual power, and at this time it had been integrated with his primordial spirit, and it was no longer possible to distinguish the difference between the original primordial spirit and the later spiritual power.

And the "liquid" state shield formed by the "medicine" power of the Tsukidan has also increased dramatically with the times, but now the Yuan Shen has also gathered into a "liquid" state, and there is a fusion force with the "medicine" power of the Tsukidan, and the two "liquid" forces blend with each other, and the Yuan Ji begins to condense at the edge of the Yuan Shen!

At this time, Lin Feng, every dozen breaths or so, has to swallow a Zhuji Dan, each time it is a large handful, the number is enough to have a dozen grains, if this situation happens to other monks, it will definitely be defeated by the huge "medicine" power of Zhuji Dan, but Lin Feng's Yuan Shen is not only strong, but the pressure caused by Yuan Ji is vast and powerful, and a dozen Zhuji Dan in front of it, there is no threat at all!

The demon pills were only decomposed, and the eight kinds of five elements of spiritual power belonging to "sex" were sent to the Yuan Shen by the immortal net according to the precise proportion, and under the control of Lin Feng's consciousness "Exercise", these spiritual powers were arranged together according to the established order, and a dense protective wall was built around the Yuan Shen, and the protective wall quickly solidified under the powerful spiritual pressure, and gradually transformed into a Yuan Ji that made the realm of the monk qualitatively change!

More than 300 Tsukidan grains have been consumed, and Lin Feng's Yuan Ji has basically taken shape, and the shield it forms by itself has a certain strength, and it can also be on its own without Tsukuji Dan, and Yuan Ji is still constantly shaping, and the demon pill in the immortal net is still being decomposed.

Three days later, the Yuan Ji finally reached saturation, the Immortal Net no longer decomposes the Demon Pill, and Lin Feng began to urge the Quenching Dragon Jue to continue to swim in the Yuan Shen and the Yuan Foundation, in order to solidify the Yuan Shen and consolidate the Yuan Ji, but this process is extremely long, Lin Feng has been cultivating in the realm of selflessness, and has long forgotten the alternation of the sun and the moon and the flow of time in the outside world.

The stone gate of the cave has been sealed in dust, Lin Feng is like a rock in the 'medicine' garden with a strong aura, his body is gradually covered with dust, if it weren't for the continuous operation of the quenching dragon trick in his body, from the outside, there seems to be no trace of spiritual breath on his body, just like a stone statue motionless.
