Zhang Di dealt with the new disciples and sent them back, while he returned to the mountain house in a leisurely manner.

As soon as he entered, he immediately changed into a serious look and walked to the back room.

The doors and windows were pasted with yellow paper, and in the middle of the room was placed a large vat, which was full of three people hugging each other, and in it was buried in the soil, and a dozen thorn saplings were planted, all of which had grown to a height of more than three inches, and were unusually strong.

The ground in the corner of the house was full of broken array disks and stone slag, about a foot high, all of which were the materials he had consumed in his recent experiment with the method of gathering spirit arrays and carving formations.

Walking to the vat first, he frowned and looked at it for a moment, and said in his heart: "This Spirit Gathering Array Disk is also too powerful, the thorn seeds planted last night, and the seedlings have grown so much today, and the growth rate has increased by three times!

He couldn't help but shake his head and smile bitterly, the expression on his face was happy and distressed, it turned out that after more than a month of hard research and carving hundreds of stones, he finally mastered the new method of carving the array, so he started to carve the array plate not long ago. This was much more difficult than carving stone, and after destroying eight or nine blank array disks, he finally succeeded in carving one.

Immediately began the experiment, moved the large vat containing water to the house, buried the soil, and buried the carved array disc into it. Since the power of the test array disc is best to have multiple seedlings, he has a total of more than sixty thorn tree seeds in his hand, ten of which were purchased from Deacon Zhang, and the remaining fifty are from the thorn fruits that grew from Wang Xianshi's body, so he simply buried twelve at a time to see how the growth effect was.

At this time, he was really surprised and inexplicable, looking around, fortunately, the doors and windows were pasted with paper in advance, otherwise it would be a real trouble to be peeped at!

After the joy, he was greatly distressed, this Gathering Spirit Array Disc is easy to use, but it is also too easy to use, right? Look, this growth is three times faster, if the Array Disc is moved to the outside Spirit Field, wouldn't it be a few days before the Kung Fu Gu Miao grows, arousing suspicion?

After thinking for a moment, he shook his head again, thinking: "This is not necessarily, the Spirit Gathering Array is to gather the surrounding spiritual energy and provide spiritual things to grow, right now I am just using a large vat to plant a dozen thorn saplings, if it is flat to the three-point spirit field, maybe the growth rate will not be so exaggerated, right?"

Thinking of this, he was itchy and couldn't wait to go to the experiment immediately, but now it was just dark and he couldn't move, so he had to wait patiently.

At last he had eaten supper and slept for two hours, and it was late at night, so he put on his clothes and went out of the house, and blew his lips softly.

With a flapping of its wings, the little yellow bird, hearing his call, flew from nearby, landed on his shoulder, and rubbed its little head a few times affectionately.

Zhang Di took out a grain of Linggu, fed it to its mouth, and said in a deep voice: "It's still the old rule, you look out for me, and I'll go to Lingtian to do things." ”

The little yellow bird swallowed Linggu, smacked its mouth in satisfaction, and flew up deftly, and its figure disappeared into the night.

Zhang Di looked at the surrounding movement again, and saw that there was no abnormality, so he went back to the house and dug out the spirit gathering array disk, and then walked to the spirit field with the spirit hoe.

It turns out that a person and a bird have reached a tacit understanding during this period of time, and the yellow bird has already told him about Ah Ming's surveillance, only at night it is the bird to monitor him, Zhang Di in order to avoid surveillance, he sleeps and rests in the house during the day, and occasionally comes out to activities in the afternoon, and only at night does he really use it to carry out various experiments.

In order to achieve such a tacit understanding, Zhang Di did not consume the spirit valley during this time, and fed the yellow bird one or two spirit grains almost every day, and the bird was full, so he gradually forgot Zhang Di's threat to it, and instead regarded him as the master, and did things for him wholeheartedly.

In this way, Zhang Di's black and white were reversed, and he was woken up by Song Bin when he was sleeping with his head covered during the day, naturally he was very angry, Song Bin touched his head and was punished by Zhang Di, and he deserved it!

In addition, the bag of Linggu left by the old donkey's head to Zhang Di is almost bottoming out, and it is enough for Zhang Di to consume two months at most, so he is also very anxious about the cultivation of Linggu, hoping to get it done quickly, so that he can free up his hands for other matters.

After all, Hao Ren will be back in two years, and everything must be ready at that time to have the certainty of restraining this person.

Zhang Di came to the spiritual field, picked up the hoe and gently dug out the second-hand spirit gathering array disk that he had buried during the day, and then buried his newly carved spirit gathering array disk, opened the bamboo pipe above his head, and suddenly a trickle of water trickled out and flowed into the eye of the spirit gathering array.

Buzz Buzz......

The array suddenly lit up, emitting a flashing white light, and at the same time it buzzed, and began to quickly mix the fertilizer and water with the spiritual energy, and convey it to the entire spiritual field.

Zhang Di stood in the center of the Lingtian, his eyes shining, nervously staring at everything in front of him, ready to terminate the experiment at any time if there was anything abnormal.

Gradually, the entire spiritual field glowed with a faint white light, and there was a rustling sound in the soil.

Zhang Di leaned down, lying at the bottom of the ditch in Lingtian, listening attentively, carefully observing with his eyes, the faint white light reflected on his slightly childish face, revealing an extremely dignified expression.

After about three hours, the rustling sound in the spiritual field became more and more intensive, and finally the tender sprouts came out, like a little starlight in the sky, flashing with soft light in the dark night.

Seeing this scene, Zhang Di breathed a sigh of relief slightly, it turned out that the rustling sound was the growth of Linggu in the soil, and now it can sprout smoothly, indicating that the growth is good, and the budding level is passed.

And look at this situation, compared to the previous experiment in the vat, the growth rate is more than twice as slow, although it is faster than the growth rate of ordinary Linggu, but it is only twice as fast, and the normal emergence of seedlings takes a day, and now it grows in the middle of the night.

After observing for a while, he finally nodded, and said in his heart: "Well, look at this, it is really the same as I expected, the power of this array plate is flat to the entire spiritual field, and it is indeed much lower than in the vat." But even so, it can't be used unscrupulously in this spirit field, the growth rate of the spirit valley has doubled, which means that the harvest period of half a year has been increased to three months, so does it have to arouse the suspicion of others?"

At this moment, he was surprised and worried in his heart, and he was pleasantly surprised that with this Gathering Spirit Array Disk, the Spirit Valley could reach two works in half a year, the problem of the shortage of the Spirit Valley was solved, and the speed of his cultivation could be greatly accelerated. The worry is that such a good thing cannot be used freely, just like a rich man pretending to be a beggar, which is really uncomfortable!

After pondering for a while, he had to dig out this array disk in distress, and then change back to the original second-hand array disk, only to see that the entire spiritual field seemed to suddenly lose its vitality, and the little light was extinguished in one fell swoop, and those Linggu seedlings that originally grew fresh and spiritual were also a little wilted.

He shook his head helplessly, right now the Spirit Valley has just grown, and the impact of temporarily replacing the array disc is not great, if the Spirit Valley is completely grown in the future, and then it will be replaced, it will definitely affect the output. What's more, looking at the power of this second-hand array disk, it is obviously not possible, and it can be worth seventy or eighty percent of the effect of ordinary new array disks, and if you use this array disk for a long time, don't look at the drip irrigation technology you use, the output of this batch of Linggu will also be affected.

Thinking of this, he also had a headache, but now that he was being watched, he didn't dare to take risks, thinking that he would do this for the time being, and think about it slowly, he should find a safe way.

At this time, the sky was already dark, and there was still work to be done, so he turned back to the house, took the twelve thorn saplings from the vat, and planted them evenly around the spiritual field, ready to serve as a protective wall. As long as the fertilizer and water are sufficient, it should be able to grow to the height of one person in three months, and then this spiritual field will be covered and form a certain protection.

At that time, if the thorn wall is dense enough to completely cover the spiritual field, maybe you will be able to use the new array disk with confidence.

Thinking of this, his heart moved, and he secretly said happily: "Yes, although the new array disk cannot be used in the spiritual field before that, I can completely use it for breeding and seedling breeding experiments! Just look at it, increase the growth rate of crops, and use it on one or two crops, won't it grow mature in a few days?"

As soon as this idea came out, he was ecstatic, it was difficult to plant in Linggu, the difficulty was that Linggu was too delicate, and the experiment of various farming methods was too risky, and one careless could ruin the entire batch of crops.

However, if there is a Gathering Spirit Array to accelerate the growth of crops, and experiments with various planting methods with a small number of crops, it can be said that the risk is avoided, and it can be achieved that others can only do it for more than ten years or even decades.
