Jiang Ning put away his phone, and thinking of Xue Yuantong's face, a smile appeared on the corner of his mouth.
Just now, with the help of the surging spiritual energy of heaven and earth, he broke through the fourth level of Qi training in one go.
Those eye-catching blue light beams and roulette wheels disappeared.
A little shorter than he expected.
Feeling the spiritual power filling his body, Jiang Ning was quite satisfied. The rewards brought by the fourth level of Qi training were quite generous.
As the watershed of the Qi training period, breaking through the fourth level of Qi training can greatly enhance magic power, spiritual awareness, five senses, and physical fitness.
With Jiang Ning's past experience, and relying on the power of the fourth level of Qi training, the number of secret techniques he can perform has increased again.
Especially, the "art of observing qi".
This is a magic spell that Jiang Ning values very much.
Observe the Qi, observe the Qi, you can observe the Qi of the world. This is a magic that can only be controlled by those who have reached the Foundation Establishment Realm.
However, if one has the assistance of a spirit gathering formation, one can use the cultivation level of the fourth level of Qi training to perform the art of observing Qi and observe the Qi of spiritual objects in the world.
Between heaven and earth, there are many derivative spiritual objects, some of which are very likely to exist in the present world, such as the derivative of space, the 'Sky Crystal Silk'.
Just pick up one strand of 'Empty Crystal Silk' and it can be refined into a storage ring.
Before reaching the foundation-building stage, there is no qualitative change in magic power and spiritual awareness, and one cannot even see the "empty crystal thread", let alone pick it up.
Ordinary cultivators at the foundation-building stage cannot obtain it, but Jiang Ning's control over magic power is so exquisite that as long as he uses the large formation as a supplement, he can perform the "art of observing qi" and then use the secret technique to complete the collection.
'Empty crystal silk' is just a by-product.
Jiang Ning's most important goal is to obtain the "Taiyi Cloud Marrow".
From beginning to end, he never forgot Xue Yuantong's illness, leukemia.
The cause of this disease is unknown. It is caused by multiple factors, even genetic factors. Although Jiang Ning usually puts some magical herbs in Xue Yuantong's food to nourish her body, he cannot be sure whether Xue Yuantong will repeat the same mistake in her senior year of high school.
Although immortal cultivators have great powers, they are not omnipotent. They still have the problem of baldness due to physical cultivation, and they can only solve the problem by relying on the Evergreen Liquid.
Not to mention leukemia, which involves deeper diseases.
If Jiang Ning himself had this disease, he would recover after breaking through the foundation-building stage, but it was Xue Yuantong who was sick.
He didn't know what Xue Yuantong's spiritual roots were like, but Jiang Ning was unwilling to let Xue Yuantong get involved in cultivating immortals for the time being as the time was not right.
He had already decided that he would keep Xue Yuantong safe.
Jiang Ning occasionally worried that his interference would disrupt the future and Xue Yuantong would fall ill prematurely.
If Xue Yuantong really fell ill early, Jiang Ning would try his best to keep her alive with elixirs.
But that is just maintenance. Even the most optimistic person would find it difficult to smile if he knew he had leukemia, a disease with a high mortality rate and extremely high pain.
With Jiang Ning's financial resources, he could indeed find a matching bone marrow for Xue Yuantong, but what if Xue Yuantong's bone marrow type is quite rare
So Jiang Ning decided to look for the spiritual object derived from heaven and earth - 'Taiyi Yunsui'.
Avoid all accidents.
After obtaining it and tempering it with spiritual fire, it can be introduced into the human body to replace her marrow, thus fundamentally eliminating the occurrence of blood cancer.
Moreover, as a spiritual object from heaven and earth, Taiyi Yunsui is extremely beneficial to the human body and can certainly prolong life.
"The sooner we can obtain Taiyi Yunsui, the sooner we can prevent Xue Yuantong from having an accident."
"Even if there is a risk of exposing the spirit formation, so what?"
Jiang Ning had a determined look on his face. He took a step forward, and his spiritual energy gathered at the small spiritual formation on the ground.
He used the small spirit formation as a paddle to move the large spirit gathering formation. Vast and surging spiritual energy covered and surged in. Rays of spiritual light condensed and penetrated into the overwhelming spiritual energy.
Eventually, it turned into a huge transparent prism that was as thin as a cicada's wing and seemed to shatter at the slightest touch, with waves of spiritual charm flowing on its surface.
The prism was like a lens. Jiang Ning stood in front of the lens. Opposite the lens was clearly the brick-red wall of the villa, but when he looked through the lens, what he saw was a colorful halo, as if it was another world.
Those halos are not real, but rather rays of energy emitted by various things.
He manipulated the small formation, controlled the movement of the prism, observed and investigated the surroundings, and scanned continuously until he saw a dark aura.
That was the 'Kongxuan Crystal'. Jiang Ning wrote down its coordinates and continued searching. What he was looking for was the 'Taiyi Yunsui'.
By noon, Jiang Ning had exhausted all his magic power, but still couldn't find it.
He took a Qi-Gathering Pill and sat cross-legged on the terrace to meditate and recover.
"It is rumored that Taiyi Yunsui is a spiritual creature derived from clouds. Do we have to go to heaven to find it?" Jiang Ning pondered.
"I haven't reached the foundation-building stage yet, so it's a bit difficult to ascend to heaven."
"Forget it, the base of the spirit boat has been refined, let's give it a try for now."
Jiang Ning's spiritual consciousness passed through the villa. In the basement, there was a two-meter-long wooden board, or it could be said that it already had the prototype of a "boat", and it would be more appropriate to call it a "spiritual wooden board".
He sent out a stream of spiritual power, guided by his spiritual consciousness, went into the basement, and brought the wooden board over.
The green silk wood was divided into seventeen layers by the sword energy, dried and tempered with spiritual fire, and refined with the help of "broken silver sand" and "wisteria mucus", and it has become extremely light.
At the same time, because the wood of Biling is inherently hard, after being made in this way, its hardness and toughness are comparable to that of elastic steel.
After Jiang Ning input spiritual power, the spiritual wood board gently floated up, almost hovering in the air, without any shaking.
Because of this, Jiang Ning engraved a formation for conducting spiritual power inside it, so that it could accommodate a certain amount of spiritual power.
Jiang Ning swallowed another Qi Gathering Pill and continued to pump spiritual energy into it. At this moment, he missed the days when he had no shortage of spirit stones. At that time, he only needed to stuff the spirit stones into the spirit boat to ensure its flight.
Jiang Ning did not rely on spirit stones, but on himself to fill the spirit wood board with spirit power.
When his spiritual power was fully recovered, he cast a Qi-hiding spell on himself and hid himself along with the spiritual wooden board.
Activating the 'Qi Observation Technique', Jiang Ning controlled the prism to ascend, and then drove the spirit wooden board to fly into the sky.
The spirit boat had not yet taken shape, and its flying speed was very slow, about ten meters per second, and it slowly rose into the air.
As they got further away from the ground, the temperature dropped, but Jiang Ning didn't need to worry given his physical condition.
When they flew to an altitude of more than 2,000 meters, the temperature had dropped to minus ten degrees Celsius. Jiang Ning continued to fly upwards until he reached more than 3,000 meters, when the temperature reached minus twenty degrees Celsius.
A magnificent sea of clouds appeared before him, with layer upon layer of clouds surging like waves and waterfalls, magnificent and boundless.
Jiang Ning had no intention of appreciating the beautiful scenery. He could only faintly sense the spiritual power drawn by the spiritual power formation below from the prism formed by the 'art of observing qi'.
If it rose any higher, it would probably shatter directly, so he didn't delay any longer and controlled the prism to explore the clouds.
Jiang Ning continued scanning and finally saw a flash of energy between the clouds.
He made a spell and grabbed towards that position. The lightning as big as a spoon was caught in his palm.
Jiang Ning scanned it with his spiritual sense and confirmed that this was the 'Taiyi Yunsui'.
He breathed a long sigh of relief; Xue Yuantong was saved.
Throughout the afternoon, Jiang Ning went up to the sky and down to the earth, extracting the 'Taiyi Cloud Marrow' to replenish his magic power.
When the sun set, he finally collected enough. After returning, he just needed to quench it with spiritual fire and then use it to replace Xue Yuantong's marrow.
On the last trip, at an altitude of 3,000 meters, Jiang Ning sat cross-legged on the "spiritual wooden board". Using the "art of observing qi", he had a rare opportunity to appreciate everything around him.
The prism kept moving, smoothly and seamlessly, but suddenly it slipped and Jiang Ning frowned.
He tapped the prism and let it swim back, looking towards an area in the north again. That area was only about one meter square.
This time, Jiang Ning saw it very clearly. The energy here was not colorful, but pure black, the color of extreme black.
Jiang Ning's expression was moved. This meant that there was no energy from any object in this area. It was completely empty.
As if being deprived.
“There are no immortal cultivators in the world today.” Jiang Ning was extremely certain. He possessed an extremely rare spiritual root, and with the help of Yuanying Zhenjun’s memories, he was able to practice in this world where spiritual energy was scarce.
Apart from him, no other immortal cultivators would be supported. This was the judgment he made as the 'Yuanying Zhenjun'.
"But why does this scene look so familiar?" Jiang Ning looked confused.
