Lu Xuan came to a spiritual field, and with a thought, the source energy of the green wood in the dantian differentiated into a faint breath.

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

Lu Xuan pressed down gently, and the faint green aura merged into a mutated spirit firefly grass.

Soon, the spirit firefly grass exuded a vigorous vitality, and under the perception of Lu Xuan's spiritual consciousness, he could even detect that it was growing rapidly.

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

Lu Xuan's mind was condensed on this mutated spirit firefly grass, and he sensed the simplest and most intense pleasure conveyed to him by the plant.

He came to a second-grade flaming fruit and did it in the same way, sending a light green air into the plant.

After observation and comparison, it was found that the effect of Qingmu Source Qi on the Flame Fruit is much weaker than that of Linghun, but it can also be clearly perceived that it can promote the rapid growth of the Flame Fruit.

"Maybe because of the different grades, although the spirit firefly grass is a mutant spiritual plant, it is still without grades. The difference between the two is quite large, so the effects of the Qingmu source energy are naturally very different."

Lu Xuan analyzed.

He looked at the grass puppet that was doing his duty not far away, patrolling the spiritual field, and summoned it. A green airflow that was obviously thicker appeared on his fingers, pressing it on the chest wrapped in gray grass.

A green dot suddenly appeared on the gray-black chest. The green dot expanded rapidly and quickly occupied the entire chest of the grass puppet.

Under the stimulation of the Aoki source energy, the gray-black grass rope that formed the body of the grass puppet extended wildly, tightly surrounding the chest, wrapping the grass puppet into a monster covered with weeds.

"I didn't expect it to help the growth of grass puppets, which is also an unexpected surprise."

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

After the grass puppet was promoted to the second grade and the large-scale picking of Lingying grass was temporarily stopped, it had not obtained the grass spirit essence liquid for a while, and the original inventory was almost consumed.

Now with the better effect of Aoki source energy, it can be used to increase the growth rate of grass puppets faster.

Lu Xuan continued to experiment and found that in addition to accelerating the growth rate of spiritual plants, he can also control the growth changes of spiritual plants to a certain extent, and even replenish the consumption of Qingmu source energy by absorbing the vitality of spiritual plants.

"This green wood source energy is of great use, but it will cause damage to the spiritual plant when absorbing vitality. Therefore, it must be used on the blade and cannot be used at will."

Lu Xuan decided that the Qingmu source energy was only used to cultivate the highest-grade spiritual plants, so as to get the reward of rich light balls as soon as possible.

After a little experiment, Lu Xuan let the light green light ball float and sink in the dantian, while he carefully inspected the spiritual plants in the sacred field.

He has used all the mutated spirit firefly grass he obtained before to condense the spirit seeds. In addition, after many induced by the 800 spirit seeds, he currently has more than 200 mutated spirit seeds.

"More than 200 mutant spirit firefly plants, plant them for another round and condense them all, and you can get one or two thousand new mutant spirit seeds. At that time, you can start a new induction experiment."

"We can almost get the improved variety of Linghuo grass."

Lu Xuan sighed secretly.

After all the spirits are used, he can immediately discover whether the change is successful. If the damage is directly abandoned, and if it is ordinary, it will continue to induce it.

After many screenings, he could get much more than the number of mutational spirit seeds after normal induced induced. In addition, the time to cultivate useless mutational spirit plants made the process of improving the spiritual plants easier and easier than other monks.

When inspecting the spiritual field, Lu Xuan found that the progress bar under another sword grass had been completely full.

He grabbed the plant like a long sword in his hand and slowly pulled out the sword grass.

With the continuous strengthening of the "Glass Bone Forging Method" and "Taixu Hualong Chapter", his bone hardness is no longer below the third-grade magic weapon. Even if the edge of the sword grass is extremely sharp, it cannot pierce the skin of his palm.

“Great quality, pretty good.”

Lu Xuan looked at the quality of the sword grass and turned to look at the slightly flashing white light ball on the ground.

"It's time to draw again!"

The two sword grasses harvested before obtained Xunlei sword balls and sword feces from the white light balls, which made Lu Xuan more expectant about the rewards of the light balls brought by this sword grass.

With a gentle touch, the light ball turned into countless light spots, piercing into Lu Xuan's body like a sharp blade.

A thought flashed through my mind.

[Harve a second-grade sword grass and obtain a third-grade flying sword purple electric sword.]

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

The flying sword is slender and about three feet long. The sword body is dark purple with light red patterns on it, and occasionally lightning lights appear.

There is a bend in the middle that is obliquely upward and downward, making the flying sword look like a lightning bolt that is directly intercepted.

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

[Purple Lightning Sword, a third-grade flying sword, is made of special ores in the Gangfeng. When used, the sword body is accompanied by thunder and lightning spiritual power.]

"The third-grade flying sword is 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 a single magic weapon.

The silver-breaking blade, red thread needle and other obtained before have long been eliminated. The second-grade Red Flame Sword is not enough in the foundation-building stage. Now this third-grade purple lightning sword just makes up for this.

"When the flying sword is released, you must first put it in the scabbard and raise it well."

His mouth curled slightly and took out the Yangxuan sword sheath.

In the ancient sword sheath, there are old flying swords that have been inserted for quite some time and the second-grade Red Flame Sword.

When pulled out, the rich fire-type spiritual power almost turned into substance, and slowly flowed out from the scabbard crack like magma.

"The nourishing effect is pretty good, and the fire-type spiritual power contained in the sword is more intense and pure."

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

"As a reward, today I will let you try a new flying sword, which comes with the power of lightning, which will ensure that you can get excited."

He looked at the Yangxuan Sword Sheath, which was still flowing out of the scabbard crack, and said with a chuckling.

When the sword sheath heard this, it trembled slightly, and a thin film of spiritual energy appeared on the crack, trying to isolate the purple lightning sword that was getting closer and closer.

Lu Xuan snorted coldly, and his thunderous sword body was straight towards the crack of the scabbard.

"A mere spiritual film, look at my purple lightning sword breaking it with one sword!"

The tip of the sword easily penetrates the spiritual film and goes straight into the depths of the scabbard.

A slight purple light appeared on the sword's body, swimming freely in the sword sheath, causing the sword sheath to tremble continuously.

After a long time, the quaint scabbard that had been trembling was calmed down, and it would shake occasionally, proving that it was not as calm as the surface.

"The red flame sword fire-type spiritual power that was inserted before still exists. Now this purple lightning sword is thunder and lightning stimulation. What's the saying?"

"Hold purple lightning in your hand and insert it into the scabbard, sparks and lightning all the way~!"
