After Qin Ming left from the Mixed Yuanzi, he went straight back to the Heaven Dou Medicine Garden.

Ren Lao had been nursing the red-veined grass in the Tiandou Medicine Garden, and when he saw Qin Ming appear, his face showed a happy look.

"Owner, you're back, this batch of red-veined grass will be harvested in ten days at most, and I plan to live here in the next few days, lest the Star Dome Array collapse again and make these elixirs fall short. ”

Ren Lao has a lot of affection for these spiritual grasses, although he also has a room in the small courtyard, but he rarely goes to live, just puts a futon next to the spiritual field, and usually sits here when he has nothing to do.

Qin Ming was a little unimpressed in his heart, this hard work was indeed hard, but there was really no way to do so, compared to the fully automatic environment of the ecological dome, it was simply dwarfed.

"I'll go and take a look at the barren medicine fields next to me to see if there is a way to reclaim these spiritual fields. ”

"Don't waste any more effort, I've tried countless methods, and even replaced all the soil in the spiritual field, but I was still transformed into a barren land by the breath of the Star Dome Great Array. ”

Ren Lao shook his head and said. He had cultivated elixirs in the Heaven Dou Medicine Garden for hundreds of years, and he had a clear understanding of every plant and tree here, and it was precisely because of this that he knew the difficulty of transforming these spiritual fields.

The only thing he could do was to take care of the last two spiritual fields left, and not let these two spiritual fields become barren as well.

"How do you know if you don't try. ”

Qin Ming smiled slightly.

When the Heaven Dou Medicine Garden was in its heyday, these thirty-six large spiritual fields and more than two hundred small spiritual fields were left, but now only two large spiritual fields were left to plant, and the remaining spiritual fields were already barren, which was simply a huge waste, and Qin Ming's character couldn't bear it at all.

Qin Ming has a lot of confidence in his heart, there is a domineering plant in the ecological ship, called Stone Crystal Grass, this plant does not absorb the fertility in the soil and grows, but relies on devouring energy crystallization to live, and then transforms the soil into a soil suitable for planting various plants like the earth, this plant is called the artifact of reclamation, and it is a necessary plant for interstellar travel.

There are a lot of stone crystal grass seeds in the ecological boat, Qin Ming is planning to use this stone crystal grass to transform those abandoned spiritual fields, the soil in these spiritual fields is so stubborn, I am afraid that only this stone crystal grass can be changed.

Qin Ming took out the stone crystal grass that had been spawned with the life crystal from the ecological boat, and saw that this stone crystal grass seedling was only an inch in size, from the root system to the leaves, it was transparent, crystal clear, like crystal.

Qin Ming's fingertips stimulated, and he poked out a small hole with one finger and planted this stone crystal grass into the pit.

Ren Lao curiously walked over from the spiritual field next to him, and looked at the stone crystal grass planted by Qin Ming, with a puzzled look on his face.

He thought that he had dealt with elixirs all his life, but he had really never seen this kind of stone crystal grass.

"This is a plant I found in the underground pit, replaced by Stone Crystal Grass, found in the barren and dark underground, it may be useful for Lingtian. Qin Ming explained casually.

What he said was not nonsense, this kind of stone crystal grass was found in the underground of a mining star, and the environment on the ground of that mining star was extremely harsh, and the aborigines relied on this plant to open up various underground worlds and survive in the underground world.

Listening to Qin Ming's words, Ren Lao's face seemed to be a little disappointed, he still thought that Qin Ming's strange plant was some kind of magical elixir, but he didn't expect it to be a plant in the mine, which suddenly made him lose confidence.

"This kind of stone crystal grass grows very quickly, and you can see it in half a month. ”

As long as there are enough energy crystals, the speed at which the stone crystal grass grows is almost like crazy growth, let alone in the Star Dome Great Array where the aura is highly concentrated.

Seeing that Ren Lao didn't trust himself, Qin Ming didn't want to explain more, but smiled and said: "Senior Ren, you are waiting in the spiritual field to be bored, why don't we make a bet." ”

"Oh, what's the bet?"

Ren Lao suddenly became interested, his daily life was to grow elixir, which was very boring, but this time with Qin Ming to accompany him, it was a lot of fun.

Qin Ming pointed to the barren land under his feet and said with a smile: "If the soil here does not change after half a month, I will lose, I will return the owner of this Tiandou Medicine Garden to you, and you will have the final say in the Tiandou Medicine Garden in the future." But if I win, you have to promise me one thing, instruct me to refine the elixir, how about it?"

"Okay, bet on it. ”

Ren Lao thought about it carefully and immediately agreed.

When Qin Ming was giving the hoe, he once said that he would listen to Qin Ming's orders within a year, and now even if he loses this time, he will lose nothing.

What's more, this young man had calm before the big event, and he was very experienced in dealing with things, and he didn't look like a seventeen or eighteen-year-old young man at all. The more he looked at Qin Ming, the more pleasing he became, and he had a plan to pass on what he had learned all his life to Qin Ming.

Even if Qin Ming lost, he would take the opportunity to propose to teach Qin Ming.

Qin Ming didn't know what Ren Lao was thinking, and when he saw that he agreed, he was sure in his heart.

He has the two big killer weapons of the ecological ship and the star spirit, which has a unique advantage for alchemy, but there is no guidance from a master, and the foundation is not solid, Ren Lao is Zhou Chongxing's servant, and he has inherited Zhou Chongxing's experience in the cultivation of elixir and the refining of elixir, which is really a rare good teacher.

It took two or three hours for Qin Ming to plant this small spiritual field of more than ten acres with Shijing grass, and with his physique in the Transformation Pill Stage, he also felt a little panting.

When there were more than 1,000 red-veined grasses planted last time, Qin Ming sold these red-veined grasses to the Heaven Dou Hall at a low price, such as today, there are still thousands of Chiyang stones left in the warehouse in the Dou Medicine Garden, which should be enough to plant a piece of Lingtian's stone crystal grass.

Qin Ming went to the small courtyard and took out the Chiyang stones, then grinded these Chiyang stones into powder, carried a bucket of red water, and poured them evenly on the Lingtian.

Ren Lao was dumbfounded, and said, "How can any plant be watered with Chiyang Stone? With so many Chiyang Stones, how many Spirit Grass Seeds can be purchased...... You just pour Chiyang Stone Yuan Liquid, forget it, it's too loser......"

Under the helm of hard work, the Heaven Dou Medicine Garden has been constantly buying this kind of spar to repair the Star Dome Great Array, and it is very poor, and finally the treasury is a little richer, and now it is all wasted on this stone crystal grass for Qin Ming, which suddenly makes him feel distressed.

"Ren senior, I can't bear to let the child trap the wolf, if I can open up the Lingtian again, what is this spar? Besides, ...... If you have Chiyang Stone Essence, I am afraid that the effect is better if you dilute it and use it for watering. Qin Ming laughed and said.

The more Ren Lao looked at it, the more distressed he became, and finally he couldn't stand it anymore, so he ran to the spiritual field on the side, sat on the futon with his back to this Qin Ming, and simply came out of sight.

Qin Ming spent half a day, and after finally pouring the water, he ignored the stone crystal grass and returned to the small courtyard.

The little Taoist Wang Longhu has been practicing even harder since he got the "Broken Cloud Meteor Skill", and Qin Ming has been going back and forth to the courtyard several times without realizing it, and he has been in the middle of being settled.

With Qin Ming's eyes, he could naturally see that Wang Longhu's luck was at a critical moment, so he didn't bother him and returned to the room by himself.

But at this moment, the star spirit suddenly came to a hint, and the process of Feng Yicao's calculation was finally completed.

Ever since he got a small leaf of phoenix wing grass from Bi Fang, Qin Ming has been calculating. It's just that this phoenix wing grass is worthy of being an incomparably precious elixir, and it is several times more difficult to calculate than the Xuanyang Vajra Fruit.

It wasn't until just now that the star spirit finally came with the news, and this phoenix wing grass had finally finished calculating.

"The DNA of the winged grass is 93% similar to the red-striped grass, and it is recommended to use the grafting method, through more than three generations of genetic modification, the mutant varieties can appear, and the phoenix winged grass will appear?"

Qin Ming looked at the results of Xingling's calculations, and was suddenly slightly surprised.

He thought it was a completely new species, but he didn't expect it to be mutated from the red-striped grass.

Thinking of this, Qin Ming hurriedly ran out of the small courtyard, walked to the spiritual field, and plucked a few red-veined grasses and said that they had an important use, which made Ren Lao roll his eyes.

After returning to the small courtyard, Qin Ming immediately teleported a few red-veined grasses through the dimensional teleportation of the Astral Key.

Qin Ming operated the humanoid robot in the ecological boat, put the red-veined grass into the cultivation tank, and then skillfully manipulated the instrument of the cultivation tank, dripping a drop of the source of life on the blade of the phoenix wing grass.

I saw that the life crystal emitted a burst of green light, and a small stream of bright pale green liquid was pumped into the ecological ship through the pipe connected to the crystal.

Now that the life crystal has almost been repaired, the extracted source of life is green as if it is jadeite, and there is a stream of green light circulating in it, crystal clear, it looks very good-looking, and the effect is much stronger than before, one drop can top two drops.

The source of life immediately took effect, and the originally dry leaves of the phoenix wing grass suddenly "came to life", and the veins were re-injected with water, and the leaves like phoenix wings stretched out, becoming as if they had just been plucked.

After doing all this, Qin Ming operated the robot, first divided the phoenix wing grass into two small pieces, and then immediately cut off a small leaf of the red wing grass, grafted one of the phoenix wing grass on it, and let the instruments near the culture tank start to run and execute the cultivation procedure!

Tick, tick.

The source of life is constantly dripping on the cultivation tank, if it is an ordinary red-veined grass, only two or three drops can be spawned to maturity, but the growth of the red-veined grass grafted with the phoenix wing grass is extremely slow, seven or eight drops of the source of life drip, and the phoenix-winged leaves seem to have just opened a small wing tip.

"Come again!"

Qin Ming's heart was also ruthless, and he continuously dripped the source of life into the cultivation tank like no money, so that the growth of this grafted red-striped grass accelerated again, and the wing-like leaves of the phoenix stretched out, as if it was about to fly.

"The first generation of plants has been cultivated, and the second generation can be cultivated!"

Qin Ming repeated his old trick, grafted another red-veined grass onto a small piece of phoenix-winged grass leaves, spawned it to maturity, and then used two grafted red-veined grasses to breed the next generation.

There are more than a dozen red-striped grasses in this generation, and I saw that the leaves of the grafted red-veined grass of the next generation faintly appeared in the shape of phoenix wings, but it was not very obvious compared with the phoenix wing grass.

This is a sign of the gradual emergence of mutation, with this good start, Qin Ming is more motivated to work, and after wasting most of the more than 1,000 degrees of energy in the Titan Star Fortress, he finally cultivated the third generation of red-veined grass.

The shape of the third-generation red-veined grass phoenix wings is also more obvious, and the number has also become more numerous, there are more than three hundred plants, at this time, it will not be able to use the cultivation tank again, Qin Ming does not have so many sources of life to squander.

According to Xingling's previous calculations, Qin Ming transplanted these red-striped grasses into the ecological dome, and at this time, the conditions for genetic mutation were ripe, so let it grow naturally, and wait for the phoenix wing grass to mutate.

This probability is not big, but it is not small either, anyway, Qin Ming is not in a hurry, just let it grow slowly, if there is a successful mutation of the plant, the ecological dome will prompt Qin Ming.
