Suddenly remembering the crystal that disappeared in the space, and looking at the bottle again, Ling Tian already had the answer in his mind.

"The bottle can be restored, but it requires an extremely large crystal."

Ling Tian was not angry but happy about the bottle absorbing such a large number of crystals. Crystals are limited but the milk of life is unlimited. In the long run, it is definitely a good thing that is sure to make money.

"Oh right, there are also those crystals!"

Ling Tian remembered that there were still five top-grade pieces, so he hurriedly summoned the space bracelet where they were stored. When he opened it, he saw that they were lying intact inside, and he couldn't help but breathe a sigh of relief.

Ling Tian did not plan to let the bottle absorb these crystals, nor would he use them to recover from his injuries. 48 drops a day were enough for him, and the space was now breeding a lot of mysterious grass, and the energy output was increased again. As long as he recovered, upgrading would not be slow.

The answer was clear. Ling Tian could continue to practice and recover with peace of mind, but relying solely on the Divine Life Milk, the space, and his own absorption, the speed was much slower.

Time flies, and another year has passed. Ling Tian has recovered almost to a certain extent from his injuries. Feeling that the alien crystal is no longer in danger of collapse, Ling Tian stopped taking the Divine Milk of Life and only guided the energy produced by the space to continuously wash and repair the alien crystal.

He decided to use the Milk of Life to vigorously cultivate and reproduce this mysterious grass.

After observing for a period of time, Ling Tian was surprised to find that the darker the color of the grass, the more energy molecules it released and the more energy it contained. Conversely, the darker the grass, the less energy it contained. This made him guess that it was related to the length of cultivation, or the year.

While cultivating the grass, Ling Tian also studied some vegetables, fruits, trees, etc. in the space. At the cost of destroying many plants, he finally gained some results.

It turns out that the Milk of Life cannot be used to cultivate these ordinary plants directly. It must be diluted to an extremely low content. Even so, not every plant can accept it.

Of the hundreds of acres of vegetables and fruits, only two longans, one lychee, one dragon fruit, and a small amount of rice were successfully grown. Moreover, it was no longer possible to grow ordinary plants on the land that had been treated with the Divine Milk of Life. This made Ling Tian depressed for a while.

Although the quantity is small, the energy produced is several times more than that of the previous hundreds of acres, which also makes Ling Tian determined to take the path of cultivation.

Day after day, Ling Tian spent most of his time recovering from his injuries and cultivating plants in space.

A month later, Ling Tian was surprised to find that the speed of space was four times that of the outside world. This was the answer he got from that handful of ripe rice.

"It's really beautiful, crystal clear, full of grains, and exudes a fragrance that makes people salivate."

Ling Tian peeled a grain of rice and put it into his mouth, chewing it slowly. It was sweet and fragrant, and the energy was rich and pure. Just this small grain was equivalent to half an ordinary corpse crystal. It was truly a rare immortal product.

After harvesting all the rice, Ling Tian planted it all again. The quantity was too small now, and it was far from achieving rice freedom. He still had to multiply more, and the speed was so fast that he didn't have to wait too long.

It's just that Ling Tian was a little too naive. Although there were thousands of rice seeds, the germination rate was only about 5/1000. The number was only five more than before, which was really depressing.

"It seems impossible to obtain sufficient quantities in the short term."

Fortunately, the space flowed quickly, and after a year, Ling Tian was able to occasionally satisfy his appetite, and several fruit trees also blossomed and bore fruit, but the number of the first fruits was not large.

I don’t know if it’s because of the different varieties, but the energy contained in fruits is far lower than that in rice. Despite this, Ling Tian still loves fruits.

Because it doesn't require management, and unlike rice, which needs to be harvested and planted every month, fruit is hassle-free and you can get permanent returns just by planting it.

The only thing that Ling Tian felt sorry for was the dragon fruit. It had been more than a year, and only a bud had sprouted out. He didn't know when he could harvest it.

…

Things change and time passes quickly!

"I've fully recovered. Ten years have passed. I didn't expect it to go by so quickly."

Besides feeling emotional, Ling Tian could hardly conceal his inner joy. In the past ten years, thanks to his persistence, the space had changed a lot. The mysterious grass was growing well and had already multiplied to an astonishing number of nearly one acre. Together with other spiritual plants, the energy molecules it brought to Ling Tian every day were as much as ten drops of the Milk of Life.

In addition, the longans, lychees and rice have been freed, and in large quantities. What excites him most is the dragon fruit.

The first fruit was produced just five years ago. The fruit surprised him as much as the mysterious bottle, because the energy brought to him by one dragon fruit was equivalent to the energy contained in two crystals. The fact that only one dragon fruit grew in five years made him speechless. Fortunately, through cultivation in the past few years, eight plants were successfully bred.

"Although all the Divine Milk of Life was used to cultivate spiritual plants, the harvest was huge. These ten years were totally worth it!"

"Now that it's fully recovered, it's time to upgrade."

The ten-year recovery process, in addition to healing his injuries, also consolidated Ling Tian's foundation to the limit. Now, as long as he has enough energy, breaking through to a smaller realm is as easy as drinking water, and even a larger realm is not difficult at all.

After adjusting for a whole day, Ling Tian was in the best state of energy and spirit. He took out the ten dragon fruits he had stored for the past ten years. With them, he would be able to reach the peak of level five perfection.

It tastes sweet and delicious, leaving a lingering fragrance on the teeth and cheeks. It is full of energy yet soft, and has a strong lasting effect. It takes three days to refine one pill. The energy is really too powerful.

"No wonder it only takes five years for one to grow. No, it should be every twenty years. The flow rate in space is four times that of the outside world."

Considering that it took so long to produce a fruit, this tremendous energy was also being cleansed.

"continue…"

A month later, all ten dragon fruits were refined, which did not disappoint Ling Tian. By the ninth one, he had broken through to the peak of level five. He wanted to try the last one to see if his luck could break through the level six barrier, but unfortunately it did not work out.

"If I want to break through, I'll need at least dozens of dragon fruits, or hundreds of bottles of Life Milk. Neither of these can be achieved in a short period of time. In that case, let's go."

Having made the decision, Ling Tian cleaned up the cave and returned to the place where he had originally fallen. His mental power surged out and connected with a tiny pattern hidden at the bottom. A curtain of light fell from the sky. This was the passage to leave the cave that he had figured out a long time ago.

Summon the Ark and enter it. With a flash of energy, the Ark appears above the crack on the seabed.

Now that the space output energy is sufficient, the Ark no longer needs to sail in economic mode.

"Void navigation mode, activated."
