Li Chen's experiments continued, but he found more and more that the aura between heaven and earth was simply the biggest obstacle to his greater discovery.

Whether it is to stimulate the change of the fruit tree or to look forward to the change of the mark itself, it seems that it is inseparable from the aura of heaven and earth.

But the aura between heaven and earth is too thin!

The thinness made him feel powerless to make a river with dew.

But although he felt helpless, Li Chen had no better way for a while. Although I saw that the immortal cultivation novel also said several ways to quickly replenish the spiritual power in the monk's body, it was either a spirit gathering formation or alchemy.

Li Chen asked himself that he didn't know any formation at all, and he didn't know how to do alchemy, but he wanted to take some medicine, but the medicine written in the book was all heaven and earth elixir, and although the name was very good, Li Chen hadn't heard of it at all, and he thought it was made up. So this road doesn't work either.

After pondering for a while, Li Chen decided to do some experiments within his ability, for example, to change the variety of fruits, which was not difficult for him to do.

There is a reason why we are doing this experiment.

No, the pears and apples he used before were all slightly larger, so can you choose some small ones to try, if you don't do it, it will have a miraculous effect.

Do what you think.

For fruit trees that are small in size, in the late autumn season, there are really not many of them.

But Li Chen still thought of one, that is, wild mountain dates! Also called wild sour jujube!

This is the most common fruit in the northern mountains, and naturally it was Li Chen's favorite when he was a child.

At that moment, Li Chen got up and took a small pickaxe and went out to the mountains.

This jujube tree can be found everywhere, but the taste and texture of the fruit on it are different. But for Li Chen, who is familiar with the grass and trees in his hometown, it is still easy to find the best ones.

No, more than an hour later, Li Chen dug out a tree that was more than half a person tall, the size of a thumb belly, and red jujube by the roots and dragged it home.

This kind of tree is very common and very lively, and it is not a rare and valuable tree, and no one cares about it.

When Li Chen came back, he planted the tree by the courtyard wall and deliberately poured a lot of water.

The sigil was then moved here.

I don't know if it's an illusion, Li Chen felt that just after putting in the mark, the temperament of the entire jujube tree instantly became different. Many of the leaves that have wilted on it instantly become emerald green, many wilted and bad bezoars that are about to fall off instantly recover as before, and other jujubes become crystal clear and jade in an instant, as if they have just been moistened by the best sunshine and rain.

Not only that, the rich sweet fragrance of mountain dates instantly filled the courtyard, so that Li Chen couldn't help but twitch his nose and take a few sharp breaths, which was very comfortable.

"Looks good!"

Li Chen felt that his judgment should be very accurate, and the consumption of aura on smaller dates was indeed lower than that of pears and apples. I also counted them by the way, a total of 188 dates.

"188, if you want to send it, it looks very auspicious!"

Li Chen was very happy in his heart, and he was reluctant to eat it, sitting cross-legged beside the jujube tree, smelling the sweet jujube fragrance and absorbing the aura, it was simply a pleasure.

Unconsciously, Li Chen actually had a feeling of selflessness. And time is slowly passing......

When the rooster sang early and a new day came, Li Chen stopped the exercises, stretched his waist, and was about to get up, but his eyes were fixed!

Because he saw that at the root of the jujube tree, at some point, four or five strange plants two or three inches tall, brown all over, covered with thorns, had grown.

This plant looks a bit like spiny cabbage to the cold eye, but it is more similar to a cactus, but it is different in color from a cactus.

"What kind of plant is this?"

Li Chen had never seen this kind of grass before, so he leaned over and touched it lightly in curiosity, and found that those thorns looked scary and prickly, but in fact they were as soft as wool and fell down when he stroked them.

However, the skin of this plant is very hard, and it feels like a hard shell to the touch.

I sniffed it with my nose again, and there was a faint smell of banlan roots!

"Could it be some kind of medicinal herb?"

Li Chen guessed that after all, there were some medicinal herbs on this mountain, and it was very possible that the seeds with medicinal herbs happened to fall in the soil of the roots of the jujube tree that he retrieved.

Thinking of this, he wanted to pull out these strange grasses, but when he stretched out his hand, he didn't know what he thought, but he took them back again, and then stopped paying attention to them.

Two days have passed, and the growth of dates is very gratifying.

After a few days of growth, these dates have become larger, almost the same size as oranges, and the fragrance is more intense, and it spreads far away with the wind.

While Li Chen was happy in his heart, he finally confirmed his judgment.

"Under the current level of aura, the size of the fruit tree is also an important factor affecting its induced effect."

But when he thought about it, how to solve it, Li Chen still had no clue.

couldn't help but be a little annoyed, looking at the jujube tree, he was not in a hurry to change the experimental subject, because he also wanted to see, if he continued to send it like this, how far could this jujube grow?

In addition, to his surprise, those strange grasses actually grew a little taller and stronger. In particular, the thorns on the body appear denser and longer. Although the color has not changed, the smell seems to be stronger, mixed with the sweet fragrance of jujubes, and it actually has a special taste.

Although Li Chen didn't know what this grass was, he felt a faint fluctuation of spiritual power from its body, although it was extremely faint, almost negligible, but Li Chen still felt it.

"Could it be the legendary elixir?"

Li Chen felt a burst of excitement in his heart, if it was true, then he couldn't be sure that he would be able to find a solution to the problem because of this.

But after all, he was still a little uncertain, and he was going to observe first, and then talk about it when he had the opportunity.

And on this day, night fell on the earth. The quiet moonlight sprinkled with a little bit of jade, which seemed to drape the earth with a faint silver veil.

According to his usual habits, Li Chen was still sitting cross-legged on the yellow area, and he was exercising his strength.

But at the same time, at the foot of a mountain a few miles away from his house, a dark shadow suddenly emerged from the grass.

After making two strange noises, the black shadow swooped away, like a leather ball, and "rolled" towards the village!

About a quarter of an hour later, in a dark corner of the courtyard wall of Li Chen's house, the soil suddenly turned around, and then, a black, grape-sized ball poked out.

The ball spun in a circle, and then "hissed" with a few subtle soft sounds, as if to confirm the surrounding environment.

Probably after confirming that there was no danger, the ball suddenly sank down, and then, the head of a small furry, small leather ball poked out.

Through the soft moonlight, you can see that the little beast has small short hair on its head, a pair of small eyes are extremely thin, and its small ears are more like radar turning left and right, with its nose, it seems to be reconnoitring the surrounding environment again.

It looks extremely cautious.

Soon, it found Li Chen, who was sitting not far away. The head subconsciously shrank down.

After a while, it may have noticed that Li Chen didn't seem to react, and it finally poked its head out again. This time, it quickly locked onto the mountain date tree, sniffed violently, and its little eyes flashed with excitement.

Li Chen was still immersed in the comfort of the fragrance and nourishment, unaware of the arrival of the little beast.

But at this moment, Li Chen's mind suddenly received a call from the "Book from the Earth", and his voice was very urgent, as if there was something urgent.

Li Chen was stunned, then he stopped the exercises, and as soon as he opened his eyes, he suddenly found an amazing scene in front of him.

I saw that on the mountain jujube tree, there was a strange little beast about half a foot long, with an earthy yellow body, like a cat, munching on dates.

Dusk saw Li Chen open his eyes, it was also taken aback, on the ball-like head, two slender little squinting eyes suddenly widened, and half of the jujube held on the short claws fell to the ground with a click.
