Jiang Ning put away his mobile phone, thinking of Xue Yuantong's face, the corners of his mouth couldn't help but show a smile.

Just now, with the help of the swarming heaven and earth aura, a wave of empowerment broke through the fourth layer of qi training.

Those eye-catching cyan pillars of light and roulette wheels disappeared.

It was a little shorter than he expected.

Feeling the spiritual power in his body, Jiang Ning was quite satisfied, and the rewards brought by the fourth layer of Qi cultivation were quite rich.

As a watershed in the Qi training period, breaking through the four layers of Qi training can greatly improve mana, divine sense, five senses, and physique.

Based on Jiang Ning's previous experience, with the mana of the fourth layer of Qi training, the number of secret techniques that could be cast increased again.

In particular, the "Art of Qi Observation".

This is a spell that Jiang Ning attaches great importance to.

Observing qi, observing qi, and observing the qi of the world, this should be a spell that can only be controlled by building a foundation.

However, if there is the assistance of the Great Array of Gathering Spirits, you can use the cultivation of the four layers of Qi to perform the technique of observing Qi and observing the spiritual qi of the world.

Between heaven and earth, there are many derivative spiritual objects, even in the current world, which are very likely to exist, such as the derivative of space, 'Empty Crystal Silk'.

The 'Empty Crystal' only needs to be extracted to make a storage ring.

Before reaching the foundation building realm, there was no qualitative change in mana and divine consciousness, and the 'Empty Crystal Silk' could not be seen at all, let alone extracted.

Ordinary foundation building realm cultivators can't take it, but Jiang Ning's control of mana is so exquisite, as long as it is supplemented by a large array, he can perform the 'Qi Observation Technique', and then use the secret technique to complete the collection.

'Empty crystals' are just incidental.

Jiang Ning's core goal is to obtain the "Taiyi Cloud Marrow".

From beginning to end, he never forgot Xue Yuantong's illness and blood cancer.

The cause of this disease is unknown, it is caused by a variety of factors, and even genetic factors, although Jiang Ning usually puts some elixir in Xue Yuantong's food to recuperate her body, but he can't be sure that Xue Yuantong will repeat the mistakes of the past in his third year of high school.

Although the immortal cultivator has great magical powers, he is not omnipotent, and he still has the body to worry about baldness, and he relies on the evergreen liquid to solve the problem.

Not to mention blood cancer, which involves a deeper disease.

If Jiang Ning himself suffers from this disease, after he breaks through the foundation, the condition will be cured, but it is Xue Yuantong who is sick.

He didn't know what Xue Yuantong's spiritual root was, but Jiang Ning was unwilling to let Xue Yuantong contact the immortal cultivator for the time being, and the time was not right.

He had already decided that he would keep Xue Yuantong safe.

Jiang Ning occasionally worries that because of his interference, he disrupts the future, causing Xue Yuantong to fall ill early.

If Xue Yuantong really fell ill in advance, Jiang Ning did his best to be able to maintain her life with elixir.

But that's just maintenance, no matter how optimistic a person is, if he knows that he has blood cancer, a disease with a high mortality rate and a high degree of pain, I'm afraid it will be difficult to smile.

With Jiang Ning's financial resources, he can indeed find a matching bone marrow for Xue Yuantong, but what if Xue Yuantong's bone marrow type is quite rare?

Therefore, Jiang Ning decided to look for the spiritual object derived from heaven and earth - 'Taiyi Cloud Essence'.

No surprises.

After taking it from her hand, after being tempered by spiritual fire, it can be introduced into the human body to change her marrow and fundamentally prevent the occurrence of blood cancer.

And Taiyi cloud marrow, as a spiritual object of heaven and earth, is of great benefit to the human body, and it is not a problem to prolong life.

'The sooner you get the Taiyi cloud marrow, the sooner you can avoid Xue Yuantong's accident. ’

'Even if you take the risk of being exposed to the Spirit Array, so what? ’

Jiang Ning's expression was firm, and as soon as he stepped down, his spiritual power gathered on the small spirit array on the ground.

He used the small spirit array as a dial to dial the large spirit gathering array, and the vast and surging spiritual energy covered and surged, and one after another spiritual light condensed, burrowing into the overwhelming spiritual energy.

Finally, it turned into a huge transparent prism as thin as a cicada's wings, like a touch of a button, and waves of spiritual charm circulated on its surface.

The prism was like a lens, Jiang Ning stood in front of the lens, and the opposite side of the lens was obviously the brick-red wall of the villa, but through the lens, what he showed was a colorful halo, as if it was another world.

Those halos were not substances, but streams of qi emitted by various things.

He manipulated the small array, controlled the prism to move, and made observations and inquiries around him, scanning continuously until he saw a dark qi machine.

It was the 'Empty Xuanjing', Jiang Ning wrote down its coordinates and location, and then continued to search, what he was looking for was the 'Taiyi Cloud Essence'.

Until noon, Jiang Ning's mana was exhausted, and he still couldn't find it.

He took a Qi Gathering Pill and sat cross-legged on the terrace to meditate and reply.

"It is rumored that Taiyi Cloud Essence is a derivative of the clouds, do you have to go to the heavens to find it?" Jiang Ning pondered.

"I haven't reached the foundation building realm yet, and it's a little difficult to go to heaven."

"That's it, the base of the spirit boat has been refined, let's try it for the time being."

Jiang Ning's divine sense passed through the villa, and there was a two-meter-long wooden board in the basement, or it already had the prototype of a 'boat', so it was more appropriate to call it a 'spirit wood plank'.

He unleashed a spiritual power, led by his divine sense, and went around the basement, carrying a plank.

After being divided into seventeen layers of sword qi, dried and quenched with spiritual fire, and then supplemented by 'Broken Silver Sand' and 'Wisteria Slime', it has become extremely light.

At the same time, because the biya wood is hard, after being made in this way, the hardness and toughness are comparable to spring steel.

After Jiang Ning input the spiritual power, this spiritual wood board was gently suspended, almost hovering in the air without any shaking.

For the reason, Jiang Ning engraved a formation for conducting spiritual power in it, so that it could accommodate a certain amount of spiritual power.

Jiang Ning swallowed another Qi Gathering Pill and continued to transmit spiritual power into it, at this time, he missed the days when there was no shortage of spirit stones in the past, when he only needed to stuff the spirit stones into the spirit boat to ensure flight.

Jiang Ning didn't rely on the spirit stone, he relied on himself, and filled the spirit wood board with spiritual power.

When he regained his spiritual power, he made a hidden decision to himself, and hid it together with the spirit wood board.

Activate the 'Qi Observation Technique' and control the prism to ascend to the sky, and then Jiang Ning drove the spirit wood board and flew towards the sky.

The spirit boat has not yet taken shape, and its flight speed is very slow, about ten meters a second, and it slowly rises into the air.

As the ground gets farther and farther away, the temperature decreases, and Jiang Ning's physique doesn't need to worry.

When he flew to a height of more than 2,000 meters, the temperature had already come to more than 10 degrees below zero, and Jiang Ning continued to go up until he reached more than 3,000 meters, and the temperature reached more than 20 degrees below zero.

A spectacular sea of clouds unfolded in front of him, cascading on top of each other, like waves and waterfalls, and the magnificence was boundless.

Jiang Ning had no intention of appreciating the beautiful scenery, the prism formed by the 'Qi Observation Technique', and the spiritual power drawn by the spiritual power array below, were only faintly induced.

If it was raised a little higher, he was afraid that it would be broken directly, but he did not delay any longer, and controlled the prism to probe the clouds.

Jiang Ning continued to scan, and finally saw a lightning-like qi machine between the clouds.

He pinched a spell and grabbed it towards that position, and the lightning bolt with the big spoon mouth was caught in the palm of his hand.

Jiang Ning's consciousness swept and determined that this was the 'Taiyi Cloud Essence'.

He let out a long sigh of relief, Xue Yuantong was saved.

Throughout the afternoon, Jiang Ning went to the sky and went to the earth to extract the 'Taiyi Cloud Essence' to replenish his mana.

When the sun set, he finally collected enough amount, and as long as he used the spiritual fire to quench it when he went back, he could use it to change the marrow of Xue Yuantong.

On the last trip, at an altitude of 3,000 meters, Jiang Ning sat cross-legged on the 'Spirit Wood Board', and he used the 'Qi Observation Technique' to appreciate everything around him rarely.

The prism kept wandering, silky and smooth, and suddenly it sliding, Jiang Ning frowned.

He lit the prism and let it swim backwards, looking back at an area to the north, which was only about a meter square.

This time, Jiang Ning saw very clearly that the qi here was not colorful, but pure black, which was the color of black to the extreme.

Jiang Ning's expression was moved, which meant that there was no qi in this area, and there was a complete vacancy on one side.

It's like being deprived.

"There are no immortal cultivators in the current realm." Jiang Ning was extremely sure that he had an extremely rare Heavenly Spirit Root, supplemented by the memory of Yuanying Zhenjun, so he could barely practice in a world lacking spiritual power.

Except for him, there will never be any more immortal cultivators, and at this time, he made a judgment as a 'Yuanying True Monarch'.

"But why is this scene so familiar?" Jiang Ning looked confused.
