After coming out of Zhijing Cave, Ling Chen sensed the spiritual energy on Zhijing Mountain from afar.

The density of spiritual energy on Zhijing Mountain is better than that of the back mountain of Xueshi Mountain, but it is far less than the center of spiritual energy at the bottom of Zhijing Cave.

However, Ling Chen's mental power is now stronger than when he came last time. As long as the amount of spiritual energy in heaven and earth is sufficient, it is not difficult for him to condense the spiritual energy in heaven and earth.

After determining the goal, Ling Chen looked for an opportunity to go up the mountain.

Unlike Mount Xueshu, the main attraction of Mount Xueshu is the mountain, and the scenic spot here is Zhijing Cave. As for Mount Zhijing, it has not been developed at all.

In addition, there are lush trees on the mountain, so as long as you enter the mountain, no one will find Ling Chen's traces.

Because there are no attractions on the mountain, there are no obstacles around Zhijing Mountain, and no one guards them, Ling Chen easily found an entrance to the mountain.

Ling Chen did not deliberately sense the density of spiritual energy, so he found a place with a lot of Davidia involucoma, and then sat down and began to condense the spiritual energy of heaven and earth.

Because the underground spiritual energy center no longer exists, the density of spiritual energy on Zhijing Mountain is not even as good as when Ling Chen first came, and the spiritual energy still tends to continue to dissipate.

Practicing in such an environment is definitely incomparable to the spiritual energy center of Zhijing Cave. Just condensing the spiritual energy of heaven and earth will consume more of Ling Chen's mental power.

However, now his mental power is much stronger than when he came last time.

In addition, his sense of energy is becoming increasingly powerful, and the tacit understanding between his spiritual energy is also deepening. Now he can easily condense energy particles within a radius of three to four thousand meters.

The skin is also more sensitive than before, and the efficiency of absorbing spiritual energy is much higher than before.

However, because the ribs and sternum were tempered, the capacity to store spiritual energy was larger. Until the sky was completely dark, the spiritual energy he absorbed filled the meridians of the dantian and the quenched bones.

At this time, Ling Chen's mental power was almost exhausted.

He was too lazy to go looking for wild game, so he ate some compressed dry food to fill his stomach and rested on the spot.

When I woke up, there was a crescent moon in the sky, and it should be midnight.

Ling Chen's mental power has completely recovered and the spiritual energy in his body has reached its peak. There is no doubt that he can temper his spine.

If you are another warrior, you can only temper your spine one by one, and there will always be some flaws at the joints.

Ling Chen is different. From the beginning, he planned to temper all his spines at the same time.

Even if he did not improve his mental power in Suzhou, it would be fine to Ling Chen want to perfectly temper his spine. Now the upper limit of mental power has increased a lot, and he can be more comfortable to temper and has higher efficiency.

However, in this way, the true energy was consumed very much. After more than an hour, he absorbed most of the spiritual energy for most of the day and was consumed completely.

At the same time, all the spines are tempered. When the day the tempering is completed, all the spines are seamlessly connected, and the effect is absolutely perfect.

But there is also a disadvantage, that is, the progress of tempering all the spines at the same time is much slower than tempering one or two spines alone.

Now, it can only be tempered to the outermost layer of the spine. Without tempering into the spinal cord, the spiritual energy cannot activate the red bone marrow in the spinal cord. The increase in qi and blood brought to Ling Chen is not much, let alone causing qualitative changes in qi and blood.

The increase in qi and blood is not large, and the qi and blood have not undergone qualitative changes, which means that it will take more time for Ling Chen to recover his mental power.

However, Ling Chen didn't care. It was nothing to spend more time to recover his mental power. Within a month, he would definitely be able to temper his spine.

There are more than three months left before the Provincial Martial Arts Competition. After tempering the spine, there are still more than two months left to temper the cervical bones and skull bones, which is more than enough time.

Moreover, once the perfectly tempered spine is tempered to the spinal cord, the qi and blood will increase, which is extremely terrifying.

It is not just an increase in quantity, but a change in quality is even more considerable.

Now, Ling Chen has exhausted all his mental power and will take more than four hours to fully recover.

But by the time he has completed tempering his spine, the time to recover his mental power will probably be reduced by half.

Just one time, spending two hours less to recover your mental power seems less obvious to the warrior's long practice career.

But there are still many organs to be tempered in the future. Whether it is tempering the bones, Dantian meridians and internal organs, it is impossible to temper them in one go. The mental power will be exhausted countless times and recover countless times.

The time to recover mental power is reduced by nearly half, which will undoubtedly greatly improve his future cultivation efficiency.

He condensed and absorbed the spiritual energy of heaven and earth twice. Until all his mental power was exhausted, Ling Chen continued to sleep.

The second day, the third day... Ling Chen absorbs spiritual energy, tempers the spine, and sleeps and rests in a cycle.

The density of spiritual energy in Zhijing Mountain is far less than that of Zhijing Cave, but the advantage is that the area is large enough and the spiritual energy is evenly distributed.

Sometimes, Ling Chen would also get some pheasants and hares to improve his food, eat dry food every day, and the birds could fade out of his mouth.

If you have enough time, there is no need to feel aggrieved your mouth and stomach for the sake of cultivation.

The goal Ling Chen set for himself was to temper the spine within one month. Judging from the progress of the tempering, this is a task that can be completed in advance.

Every day, I absorb spiritual energy, temper my spine, and sleep and rest. This kind of hard-working life is boring, but for Ling Chen, I enjoy it.

It feels wonderful that your entire spine is transformed from the outside to the inside.

Especially with such a terrifying cultivation progress, after leaving, you can gain a lot of shock and shock, and Ling Chen is even more fulfilling!

On the 20th day, Ling Chen finally tempered his spinal canal.

The spinal cord is inside the spinal canal.

It was the first day that the spinal cord was tempered. Ling Chen's qi and blood grew rapidly like a mountain torrent!

If Ling Chen's original amount of qi and blood was one, after tempering the spinal cord, the amount of qi and blood was almost doubled!

This is only the first day. After tempering the spinal cord, Ling Chen's qi and blood volume is estimated to be three times that of the original one!

Not only the quantity, but also the density of qi and blood have also changed fundamentally.

Ling Chen felt that if the same volume of blood was once a pound, it would weigh three pounds now!

Normally, after a warrior tempers the spine, the amount and density of qi and blood can double, and the effect will be very good, twice... It is simply unheard of!

This is the benefit of perfectly tempering the spine!

Moreover, the spinal cord also belongs to the central nervous system, and the upper limit of mental power brought about by tempering the spinal cord is also very large!

How big is it?

Anyway, every time Ling Chen's qi and blood flow backwards, the upper limit of mental power brought by the impact of the qi and blood on the Ming Eye is not as great as the spinal cord tempering!

The quantity and quality of qi and blood have been greatly improved, the upper limit of mental power is also increasing, and Ling Chen's efficiency in tempering the spinal cord is getting higher and higher.

It was originally expected to be one month, but it took only more than twenty-four days to temper the spine!

Basically one week ahead of schedule, break through to the late stage of Huajin!
Chapter completed!
