Lu Xuan came to a spiritual field, and his mind moved, and the green wood source qi in the dantian differentiated into a faint breath.

A faint green qi suddenly appeared on the index finger of his right hand, and the green qi was full of vitality, causing many spiritual plants around him to unconsciously stretch their branches and leaves to this side.

Lu Xuan pressed down lightly, and the faint green qi merged into a mutant spirit firefly grass.

Soon, the Spirit Firefly Grass exuded vigorous vitality, and under Lu Xuan's spiritual sense, he could even sense that it was growing rapidly.

The growth rate is several times higher than normal, and after half a moment, it gradually decreases.

Lu Xuan's mind was condensed on this mutant spirit firefly grass, and he sensed the simplest and intense pleasure that the plant transmitted to him.

He came to a second-grade flame fruit again, and concocted it in the same way, sending a faint wisp of green qi into the plant.

Observation and comparison showed that the effect of Aoki Source Qi on the Flame Fruit was much weaker than that of the Spirit Firefly Grass, but it could also be clearly perceived to promote the rapid growth of the Flame Fruit.

"Maybe it's because of the different grades, although that spirit firefly grass is a mutant spirit plant, it is still no grade, the difference between the two is not small, and the effect of Aoki's source qi is naturally very different."

Lu Xuan analyzed.

He looked at the grass golem that was doing his duty and inspecting the Lingtian not far away, summoned it, and a much thicker cyan air flow appeared on his fingers, pressing on the grass puppet's gray grass wrapped in the chest.

A green dot suddenly appeared on the gray-black chest, and the green dot expanded rapidly, quickly occupying the entire chest of the grass golem.

Stimulated by Aoki's source qi, the gray-black grass rope that made up the body of the grass golem stretched wildly, tightly surrounding the chest, wrapping the grass golem into an overgrown monster.

"I didn't expect to be able to help the grass golem grow, but it was also a bonus."

Lu Xuan felt that the grass puppet was in good condition and muttered to himself.

After the grass puppet was promoted to the second grade, and the large-scale harvesting of the spirit firefly grass was temporarily stopped, it had been a while since the grass spirit essence liquid was obtained, and the original inventory was almost consumed.

Now with the more effective Aoki Source, it can be used to increase the growth rate of the Grass Golem faster.

Lu Xuan continued to experiment, and found that in addition to speeding up the growth rate of spirit plants, he could also control the growth changes of spirit plants to a certain extent, and even replenish the consumption of Aoki's source qi by absorbing the vitality of spirit plants.

"This Aoki source qi is extremely useful, but when it is replenished by absorbing vitality, it will cause damage to the spirit plant, so it has to be used on the blade, and it cannot be used at will."

Lu Xuan decided that the Aoki Source Qi would only be used to cultivate the highest-grade spirit plants, so that he could get the rich light group rewards as soon as possible.

After a little experiment, Lu Xuan let the pale cyan light cluster float and sink in the dantian, while he carefully inspected the spirit plants in the spiritual field.

The mutant spirit grass he obtained before had been used by him to condense the spirit seeds, and after many inducements of those eight hundred spirit seeds, he currently had more than two hundred mutant spirit seeds.

"More than two hundred mutant spirit grasses, one more round of planting, all condensed, you can get one or two thousand new mutant spirit seeds, and then, you can start a new induction experiment."

"I'm almost able to get an improved variety of Spirit Fireflies."

Lu Xuan sighed secretly.

After the spirit is planted, he can find out whether the mutation is successful or not at the first time, and the damage will be discarded directly, and the ordinary will continue to be induced.

After many screenings like this, he was able to obtain far more than the number of mutant spirit seeds after normal inducement, and the time for cultivating useless mutant spirit plants was omitted, making the process of improving his spirit plants easier and simpler than that of other monks.

Inspecting the Spirit Field, Lu Xuan found that the progress bar under the other sword grass had been completely full.

He grasped the sword-like plant in his palm and slowly pulled out the sword grass.

With the continuous cultivation of the golden chalcedony jade liquid, the continuous enhancement of the "Glass Forging Bone Method" and "Taixu Dragon Chapter", the hardness of his bones is no longer under the three-grade magic weapon, even if the edge of the sword grass is extremely sharp, it cannot pierce the epidermis of his palm.

"Superior quality, not bad."

Lu Xuan inspected the quality of the sword grass and turned his head to look at the white light cluster that flickered slightly on the ground.

"It's lottery time again!"

The two sword grasses harvested before obtained the Xunlei Sword Pill and the Sword Fetus respectively from the white light cluster, which made Lu Xuan look forward to the light group rewards brought by this sword grass a little more.

With a light touch, the light cluster turned into countless points of light, piercing into Lu Xuan's body like a sharp blade.

A thought crossed his mind.

[Harvest a second-grade sword grass plant, and obtain a third-grade flying sword purple electric sword.] 】

The thought flashed, and a flying sword with a strange shape appeared in Lu Xuan's palm.

The flying sword is slender, about three feet long, and the body of the sword is dark purple, with pale red lines on it, and occasionally electric light emerges.

In the middle, there is a bend that goes diagonally upwards and falls, making the sword look like a bolt of lightning that has been intercepted directly.

Lu Xuan's mind was condensed on this strange flying sword, and he soon learned the details about it.

[Purple Electric Sword, Sanpin Flying Sword, made of special ore in Gangfeng, when used, the sword body is equipped with thunder and lightning spiritual power. 】

"Sanpin Flying Sword, just right for me now."

After Lu Xuan was promoted to the foundation building realm, although he had many third-grade treasures on his body, he did not have any of them.

The Split Silver Blade, Red Line Needle, etc. obtained before have long been eliminated, and the second-grade Red Flame Sword is also a little insufficient in the foundation building stage, and now this third-grade purple electric sword just makes up for this.

"The flying sword is on the market, and it must be put in the scabbard first."

The corners of his mouth were slightly hooked, and he took out the scabbard of the Yang Xuan sword.

In the ancient scabbard, there is currently an old flying sword that has been inserted for quite a while, a second-grade red flame sword.

When it was pulled out, the rich fire-based spiritual power almost turned into substance, slowly flowing out of the crack in the scabbard like magma.

"The nourishing effect is not bad, and the fire-based spiritual power contained in the sword body is even richer and purer."

Lu Xuan looked at the Red Flame Sword in his hand and sighed.

"As a bonus, I'll let you try a new flying sword today, with the power of thunder and lightning, which is guaranteed to make you strong."

He looked at the Yangxuan scabbard where hot magma was still flowing out of the crack in the scabbard, and said with a smile.

Hearing this, the scabbard trembled slightly, and a film of aura quietly appeared on the crack, wanting to isolate the purple electric sword that was getting closer and closer.

Lu Xuan snorted coldly, and the thunderbolt-like sword body went straight to the crack in the scabbard.

"Just a film of spiritual energy, watch my purple electric sword break it with one sword!"

The tip of the sword easily penetrated the aura film and went straight into the depths of the scabbard.

A subtle purple light appeared on the sword's body, swimming freely in the scabbard, causing the scabbard to tremble.

After a long time, the quaint scabbard that had been trembling subsided, and only occasionally shook a little, proving that it was not as calm as it seemed.

"The remnants of the fire spiritual power of the Red Flame Sword inserted in before are still there, and now this purple electric sword has thunder and lightning stimulation, how can you say it?"

"With purple electricity in your hand, you can spark and lightning all the way~!"

Lu Xuan couldn't help but laugh.
