Eradicated the old way that planted Gu for Bai Ruoxi, and everyone finally breathed a sigh of relief.

During this time, Bai Ruoxi collected the porcelain vases brought back by those little spirit sparrows according to Gu Changsheng's instructions, extracted the condensed spiritual mist inside, and stored them in a porcelain jar with formation patterns.

Three months later, a light green mist had already appeared in the porcelain jar, and Gu Changsheng felt that the time was ripe, and planned to teach Bai Ruoxi the technique of catalyzing spirit grass.

The three of them came to a half-acre medicinal field next to the secret room, where all the spiritual grasses planted were old, and one of the spiritual grasses called 'Hundred Leaf Ginseng' was the most and the most precious.

As long as this ginseng is more than 100 years old, mortals can prolong their lives if they eat it. Cultivators usually use this ginseng to make a 'ginseng elixir' to improve the realm, and this pill is effective for cultivators below the foundation building period.

It's just that because this ginseng has been indiscriminately mined and dug up, it has disappeared in the Taiqing Mountains for many years, and it is priceless in the Fang Market, and it is very difficult for many high-level cultivators to get one or two.

Now, Gu Changsheng took out a palm-sized array weapon from the storage bag, and injected a levitation technique on it, causing it to stop directly above a 'Hundred Leaf Ginseng' out of thin air.

This magic circle was also specially refined by Gu Changsheng after hundreds of years of research, and it consumed a lot of resources.

Under Gu Changsheng's guidance, Bai Ruoxi shot a green light into the array, and released the semicircular green wall in the array, completely enveloping the spirit grass in it.

Just when Bai Ruoxi thought that this formation was formed, changes began to continue to occur on the array, and a wonderful scene also appeared on the opposite lower formation wall.

When the array was formed, it could be seen from the outside that many green light spots were gathering and being sucked into the array wall, and this phenomenon only lasted for a short quarter of an hour before stopping.

Then, the dark green formation pattern on the body of the array suddenly emitted a dazzling green light, and on the surface of the array wall, several golden words and symbols appeared.

These strange characters, which look like golden tadpoles, have very strange strokes, and have an indescribable ancient charm contained in them, and they are constantly flickering and swimming on the walls.

It's just that this kind of alternative formation mutation only lasted for a moment, and then disappeared, leaving only a few protruding golden monster characters around the formation wall, as if this formation was ready.

After this period of time making the formation with his eldest brother and witnessing the strange things that happened in it, Gu Feichen next to him was no longer as fuss about these strange phenomena as he was at the beginning, even if something more strange than this happened in this small formation, it would no longer make him so stunned.

"Excellent! You can inject wood spirit mist into the array, remember to be slower and softer, and if you want to be fast, you can't reach it! Gu Changsheng was like an old man guiding his apprentices, staring at the array with his hands behind his back, looking old-fashioned.

Hearing the command, Bai Ruoxi pointed towards the porcelain jar where the wood spirit mist was stored, and a cloud of green smoke slowly rose and poured into the array from above the array.

There were more and more wood spirit mist in the array, and there was gradually a hazy feeling in the array. Seeing this, Bai Ruoxi began to control the array weapon, condensing these mist, turning them into very fine droplets that gathered on the leaves of the spirit grass.

As the wood spirit mist in the array gradually disappeared, a faint layer of green light began to appear on the leaves of the 'Hundred Leaf Ginseng'. There were countless tiny turquoise droplets, slowly trembling on the surface of the leaves, and the array wall gradually emitted green light, which became stronger and stronger, and finally reflected the entire medicinal field into a green patch.

For the next few hours, every time a period of time passed, the 'Hundred Leaf Ginseng' would have an extraordinary vision. Countless filaments of light, like moths to a fire, were sucked into the veins of the leaves by the spirit grass, and then turned into a large number of small points of light, which were greedily devoured by this spirit grass.

Seeing that this was indeed effective, Bai Ruoxi began to inject wood spirit mist into the formation weapon after the green light of the formation disappeared, and kept repeating the same practice, just like this for a month.

Whenever that 'Hundred Leaf Ginseng' absorbs the Wood Spirit Mist, Bai Ruoxi will replenish the Wood Spirit Mist to the array in time, and this 'Hundred Leaf Ginseng' also lives up to expectations, its leaves gradually turn from turquoise to dark blue, and then from dark green to black, and finally after its leaves become completely black and shiny, it has become a rare thousand-year-old 'Hundred Leaf Ginseng' in the world.

This test was very successful, and it seemed that if there was enough Wood Spirit Mist, the year of the 'Hundred Leaf Ginseng' could continue to be improved, but for Gu Changsheng, there was no need to do it now.

As long as he knew that this method was indeed feasible, he didn't need these medicinal herbs that were too old now, hundreds of years of medicinal herbs were enough for a few of them.

Under Gu Changsheng's reminder, Bai Ruoxi was about to withdraw the formation, and at this time, there was not much wood spirit mist left in the porcelain jar.

Gu Feichen squatted on the ground with a big grin, subconsciously wanting to try to smell the spirit grass. The moment the formation was withdrawn, he suddenly smelled a strong medicinal fragrance.

Smelling this medicinal fragrance, even Bai Ruoxi was slightly stunned, but then her heart moved: "Is this ......?"

She couldn't help but crouch down as well, carefully inspecting the 'Hundred Leaf Ginseng' that exuded a strong fragrance.

Is this the spirit grass from a month ago? Bai Ruoxi couldn't believe her eyes, and gently stroked the spirit grass with her hand, she had never seen a thousand-year-old 'Hundred Leaf Ginseng', and it was not even recorded in the medicine book, so she couldn't be sure if this 'Hundred Leaf Ginseng' was a thousand-year-old spirit grass.

Gu Feichen was even more exaggerated, this kid thought he was dreaming, so he actually pinched his face with his hand a few times, and didn't stop his masochistic behavior until he was in some pain.

"The leaves of this 'Hundred Leaf Ginseng' are black and bright, the ginseng flower on it has opened nine petals, and the skin of the ginseng fruit has also turned black, this is a thousand-year-old 'Hundred Leaf Ginseng', haha! Ha ha! Gu Changsheng couldn't help it, even if he was usually able to stop like water, he couldn't help but look up to the sky and laugh at this time.

In the fairy world, this kind of spiritual grass can't enter his eyes, but in the human world where resources are scarce, this is a treasure! At least he had never seen a hundred-year-old 'Hundred Leaf Ginseng' in Fang City, let alone a thousand-year-old one.

"Now we are lucky, in a month, this 'hundred leaf ginseng' with more than 50 years of medicinal properties has become a thousand-year-old spirit grass, looking at the color of the leaves, the shape of the fruit, and the fragrance of the petals, it is completely a rare spirit grass that has matured for more than several years." Gu Feichen, who was next to him, carefully checked the herbs again, and made sure that they were exactly the same as what was said in the secret note left by his grandfather, and they were really precious medicinal materials that had been around for many years.

"If you follow this method to ripen the herbs, as long as the Wood Spirit Mist is sufficient, wouldn't there be as many precious medicinal materials as you want! And you can also exchange these precious medicinal materials for various rare materials, so that the path of cultivating immortals can become much smoother. Bai Ruoxi couldn't hold back the excitement in her heart and began to think about it.

"Don't make a big deal about it, or you'll be killed!" Remember!! ”

Under Gu Changsheng's reminder, the two quickly calmed down.

Bai Ruoxi gently, very skillfully, took the ginseng fruit off the spirit grass.

Can't believe it! Bai Ruoxi looked at the ginseng fruit in his hand in surprise.

It was so effortless, and it didn't take any skill at all, so the problem of the spirit grass seed, a big problem that the Gu Family Medicine Garden had not been able to solve, was solved so easily?

When Bai Ruoxi confirmed that what was happening in front of her was indeed true, she carefully wrapped the seeds and put them in the storage bag.

Gu Feichen and Bai Ruoxi, the young couple, couldn't hold back the excitement in their hearts anymore, hugged each other like children, and sang and danced next to the medicine field.
