Continuously transmitting true element energy to Xin Luyao is simply unrealistic for Xin Yu, and even if he can support it, with the current transmission speed, he can't keep up with the speed of Xin Luyao's vitality.

Therefore, after discovering that his behavior was a drop in the bucket, Xin Yu unexpectedly thought of using the Qi Nourishing Pill to maintain Xin Luyao's life.

Before he practiced the astral arts, when Xin Yu was cultivating the Tai Chi Formation, he suddenly caused the rapid transformation of his body's energy into internal force, which was very similar to Xin Luyao's current situation. At that time, Xin Yu used various qi-replenishing herbs such as ginseng to nourish at the beginning, and barely survived that level of life and death, and it was not until he figured out the refining method of the Qi Nourishing Pill and successfully refined the Qi Nourishing Pill that he was completely free from the troubles caused by the change of True Qi, and he also raised the Qi refining practice to a very high level because of the Qi Nourishing Pill.

Now Xin Luyao has to treat her very similar to his original situation, the same life energy has been absorbed in large quantities, far exceeding the speed of his own recovery, using pills such as Qi Nourishing Pill to give her tonic, although it can't fundamentally solve the problem of her vitality draining, but it can also improve her current situation, at least not to die after a day or two because of the complete loss of vitality.

The planet is very strange, let's say that this is a forbidden area for life, and indeed not even the tiniest animals like insects have been found, and even bacteria are only a class that decomposes the decaying branches and leaves of plants.

And to say that this planet is full of life, except for the ocean, lakes and some rivers, the whole planet is covered with green vegetation everywhere, and even the planet's two levels and extremely high altitude and extremely harsh climate places, there are also all kinds of plants, as if the vitality absorbed by this planet from the creatures that stay here and there is completely transmitted to these plants.

However, for Xin Yu, especially for refining Qi Nourishing Pills, it didn't matter if there were animals or not, because in the past seventy years, the various other types of Qi replenishing pills that Xin Yu had explored had all been taken from plants.

This planet is definitely a big treasure house for alchemists, abundant plant resources, as well as rich plant species, and even because it is extremely suitable for the environment for plant growth, the medicinal properties of the plant medicinal materials here are more intense than the outside world...... This is the conclusion that Xin Yu got from the nine-leaf and seven-star grass that can be seen everywhere.

Under normal circumstances, because the leaves of the Seven Star Grass are relatively long, most of them are curly or soft and lying on their stomachs, and the most suitable place for the growth of the Seven Star Grass in time is only seven leaves. But in the dense seven-star grass in front of Xin Yu, most of the leaves of the seven-star grass are straight to the sky, and they look like "overnutrition", and almost every seven-star grass plant has nine long blades of grass.

And Xin Yu casually picked a seven-star grass leaf and put it in his mouth, and was shocked by its full medicinal properties. In the formula of the Seven Star Grass Refining Healing Pill Soul Returning Pill, it is an important medicinal material between the main medicine and the auxiliary medicine, generally refining a Soul Returning Pill, the Seven Star Grass that needs to be used is about six to eight plants, if the medicinal properties are not enough, it is even necessary to extract the essence of more than a dozen Seven Star Grass.

However, if you use the Seven Star Grass grown here as medicine, you only need half a blade of grass at most, which is enough for the medicinal properties of a Soul Returning Pill.

And a relatively ordinary medicinal material like the Seven Star Grass is almost everywhere within the scope of Xin Yu's fine perception of spiritual power, and judging from the shape of the growth, most of them are the kind that can be fully grown at a glance.

Not only that, after roughly dissipating his spiritual power, Xin Yu found that on the grassland within a radius of a hundred miles around him, there were not only medicinal materials such as the most "ordinary" Seven Star Grass, but also other medicinal materials that were rare in the original world, such as Soul Rejuvenation Grass, Immortal Grass and other extremely cherished medicinal materials, and even various herbs that he couldn't name. It can be said that this is completely a paradise for alchemists, and if it weren't for the fact that the environment here is too weird, Xin Yu would definitely regard this place as his main base in the Plum Blossom Star Realm.

However, although this place is by no means a good place, the temporary solution to the situation of Xin Luyao's vitality is because of the abundant and rich medicinal resources, which makes Xin Yu very happy. If this planet is really an absolute forbidden area for life, and even plants can't grow, then if you want to solve the situation of your beloved daughter, you really have to make him blind.

If you want to solve Xin Luyao's current problem, the Qi Nourishing Pill is undoubtedly the most suitable pill. Moreover, because the Qi Nourishing Pill was the first elixir that Xin Yu pondered, and it was also the pill he refined the most, in the absence of a Super Dan Furnace, Xin Yu was also sure enough to refine enough Qi Nourishing Pill in the shortest possible time. Moreover, Xin Yu believed that with the medicinal properties of the medicinal materials on this planet, it would be easy to refine a "strengthened version" of the Qi Nourishing Pill.

With Xin Yu's flight speed, it would definitely not take long to complete the medicinal materials in all parts of the planet of the size of the earth, and to collect enough weights.

However, when Xin Yu circled the planet high in the sky, he found a very serious problem. That is the most important medicinal material in the Qi Nourishing Pill, Snow Grit, which does not grow at all on this planet, even the poles of the planet and the top of the highest mountain peak on this planet, in such an environment that is most suitable for the growth of Snow Grits, Xin Yu did not find even a shadow of Snow Grits.

All the other medicinal materials have been picked in sufficient quantities, but the main medicine of snow grits has not been picked, so it is naturally impossible to refine the Qi Nourishing Pill...... In fact, it is not that it is absolutely impossible to refine, after all, several other flavors of medicinal materials also have the effect of replenishing qi, but without the combination of snow grits, the effect of refining the pill with several other flavors of medicinal materials is far less good than the mature formula that Xin Yu explored, and moreover, refining the pill pays attention to the compatibility of a monarch and the balance of medicinal properties.

Therefore, after the lack of a taste of medicinal materials, the proportion of all medicinal materials in the entire Danfang needs to be recalculated and tried. Otherwise, it doesn't matter if the effect of the refined pill is not good, but if the refined pill becomes a poisonous pill because of the conflict of medicinal properties, the problem will be very serious.

Although the medicinal properties of the several medicinal herbs used in refining the Qi Nourishing Pill are very mild, even if they are indiscriminately combined, there will not be too many problems, but if the medicinal effect is not optimal, it will not help Xin Luyao's current situation, right?

Of course, the absence of snow grits does not mean that the Qi Nourishing Pill cannot be refined, and when Xin Yu provided the entire Astrology World with an unlimited amount of Qi Nourishing Pills, it was not all snow grits provided by the Xue Mo Cui family. After all, the growth environment of snow grits is extremely harsh, even if there are many places suitable for the growth of snow grits in the entire snow desert, but the mature snow grits that can be dug up every year are only tens of thousands.

Don't look at the number of tens of thousands, it seems to be huge, but the entire snow desert, which is equivalent to the land area of the earth, produces only tens of thousands of snow grits every year, so you can imagine the preciousness of this medicinal material. At the beginning, in order to pursue a better qi replenishment effect, Xin Yu chose this medicinal material with sufficient medicinal properties.

However, in fact, the main medicine designed by Xin Yu at the beginning of the Qi Nourishing Pill was ginseng, which is also very precious, but it is not rare.

Since there is no snow grits on this planet, Xin Yu has no choice but to "retreat to the second" and use ginseng as the main medicine of the Qi Nourishing Pill. It's just that what makes Xin Yu feel a little inconvenient is that the growth environment of ginseng is very different from that of snow grits.

Snow grits generally grow on snowy plains, even at high altitudes, but also in relatively "open" places. Therefore, in the absence of shelter, Xin Yu can fly at high altitude and search at the same time, maybe the speed of snow grits is much faster.

Ginseng, however, is different. It is described in the encyclopedia as follows: ginseng is a perennial herbaceous plant, likes shade, has no stomata and palisade tissue, cannot retain water, the temperature is higher than 32 degrees and the leaves will burn, and the canopy density is 07-08. It usually blooms in 3 years, bears fruit in 5-6 years, blooms in May-June, and fruits in June-September. It grows at an altitude between 33 degrees and 48 degrees north latitude, and is hundreds of meters old in coniferous and broad-leaved mixed forests or deciduous broad-leaved forests.

In other words, except for those cultivated and cultivated, naturally grown ginseng cannot appear in open areas. In this way, if Xin Yu wants to obtain ginseng, he must enter the woods...... Because it is still difficult for Xin Yu to accurately find ginseng under the heavy shade of leaves. Therefore, it became inevitable to enter the woods and search.

However, in the woods, there were branches and leaves everywhere, and even if Xin Yu could easily destroy a forest, it would be impossible for him to increase the speed of the flight search to the speed of the open space. And time is the most scarce thing for Xin Yu.

Xin Luyao can support a limited amount of time, and Xin Yu must also refine the Qi Nourishing Pill before this limited time. Because it is inconvenient to carry too many things when traveling interstellarly, and the space that Xin Yu's storage ring has is only the size of a basketball, Xin Yu does not have a suitable alchemy tool in his hand at all. In such a situation, Xin Yu had to refine it with the method of heart refining. However, although the heart alchemy pill is more effective than the medicinal materials refined in the Dan furnace, because it is all based on the skills of the alchemist and the true yuan support, it is not as convenient to control as it is to use the Dan furnace, and the refining speed is not as fast as refining it with the Dan furnace.

Therefore, in terms of the time required to collect medicinal materials, it is bound to not be allowed to take too long. If Xin Yu went into the woods to look for ginseng, it would inevitably take a long time, or even half a day, which was normal.

However, no matter how difficult it was, he had to do it, because he had no other choice.

After carrying the daughter who was weakened to the point of coma on her back and securing it with a belt...... If his strength was still at its peak, Xin Yu didn't need to be so troublesome at all, as long as he used his spiritual power or true yuan to surround Xin Luyao, even if his speed reached the speed of light, it would be impossible to lose his daughter.

It's just that the current situation is that his strength has dropped to a minimum, and the true yuan energy is also the only source that he can use to replenish his spiritual power, so if he can save a little energy, Xin Yu will not be willing to waste it.

Just after Xin Yu chose a forest that was most likely to grow or the most suitable for ginseng growth, and then took Xin Luyao in, he suddenly found that the woods on this planet were very different from all the other woods.

It stands to reason that every forest is a complete ecosystem, and of course, without animals on the Lone Star, it is naturally impossible to have an ecological cycle of a complete food chain. However, even the growth state of the plant should be under the tall trees that grow these shrubs that strive for the sun, under the shrubs, there are some tenacious grasses, and on the darker and damp surface, or on the surface of some stones, there should be mosses and other ferns.

However, when Xin Yu just entered the edge of this forest, he found that it was not the case at all, the low shrubs were forested, and in this area they were completely shrubs, and there were absolutely no grasses, and as he gradually went deeper into the forest, the height of the trees became higher and higher, like a ladder. In these "higher" areas, all the trees grow, and there is no room for shrubs at all, let alone grasses.

At this time, Xin Yu recalled the strange feeling when he looked down on the planet from above, that is, the distribution of plants on the planet seemed to have been artificially planned. In an area, if it is an arbor, then all the trees that grow are trees, and if it is a shrub, there will never be a tree species taller than a shrub in the whole forest, and in the grassland, it is even more obvious that there will never be a shrub that is a little taller than the grass.

This discovery made Xin Yu feel panicked, because ginseng is also a herbaceous plant, and under those tall trees or low shrubs, will there be room for ginseng to grow?

If not, wouldn't it have become a luxury for him to refine the Qi Nourishing Pill, and as he gradually penetrated into this large area, it almost covered most of the continent...... If you count the area, it must be at least the size of Australia...... When he was in the forest, something happened that made Xin Yu feel even more frightened...... Or that this situation has always existed, but Xin Yu only discovered that the closer he got to the center of the forest, the more the range that his spiritual power could perceive was shrinking, as if he was suppressed by something
