Summer gradually passed, the leaves of the trees in the park gradually withered yellow, with the autumn wind, whirling past him, Chu Zihan watched quietly, those fallen leaves in the air like rootless duckweed, slowly floating here, falling into the small lake in the center, ripples, soaked by the lake water for most of it.

"It's been six months" Chu Zihan looked at the fallen leaves in the lake and sighed softly.

It has been three months since Chu Zihan unexpectedly met Wang Yi, and there is still no progress in the search for telekinetic cells, but he has also grown from more than one meter three months ago to nearly two meters, and the most developed roots have not surprised Chu Zihan to reach a depth of 8 meters, which can be described as a rapid growth.

The Bronze True Yuan has also increased to twenty-eight, which can be used to assist in development, which can increase the growth rate by nearly 3%.

At the same time, in the past six months, the little green worm and the little lark have also continued to provide Chu Zihan with the power of faith, but the little lark, which is obviously many times stronger than the little green worm, has the same power of faith as the little green worm.

They can only produce one-sixtieth of the power of faith every day.

At the beginning, Chu Zihan thought that all believers had the same amount of faith power, regardless of the difference in strength.

But this conjecture was quickly overturned by him, and when he recalled the difference between the little green worm and the little lark, he discovered something very important.

The little green worm is a fanatical believer, and the little lark is just a pan-believer.

Could this be because of the difference between the levels of believers, so Chu Zihan used all the power of the two beliefs generated in the second month on the little lark.

The result was that he was ecstatic, the little lark actually changed from a pan-believer to a devout believer, and he could produce one-twentieth of the power of faith every day.

By the fourth month, Chu Zihan used all the power of faith dedicated by the little green worm and the three powers of faith dedicated by the little lark to the little lark.

After that, the little lark changed from a devout believer to a fanatical believer, and he could produce one-tenth of the power of faith every day, and three powers of faith in a month.

As long as he waits until the end of next month, Chu Zihan will be able to harvest the power of 7 faiths.

So far, Chu Zihan has also divided a complete hierarchy of believers, pan-believers, devout believers, and fanatical believers.

"Then there should be two reasons for the strength of believers' faith.

One is the level of believers, for example, the little lark is a pan-believer and can only produce one-sixtieth a day, and the fanatical believer can produce one-tenth a day.

And the other is the degree of enlightenment of the believer's wisdom, and at the same time, the fanatical believer, the little green worm can only produce one-sixtieth of the power of faith every day, and the little lark can produce one-tenth. ”

In the past few months when Chu Zihan was studying the power of faith, the weather has become hotter and hotter, and even in autumn, it has not improved at all, and it is even more serious than a few months ago.

The same is true of the rainfall, which has only rained five times in the summer, and it has not rained much, and there are not many people in the park that used to be overcrowded.

According to them, not only the temperature in Yangcheng has hit a new high, but most of the other surrounding cities are also the same, and even many cities in the west have experienced severe drought.

And Chu Zihan began to plan to store rainwater as early as the moment the weather was abnormal......

It's just that as the weather gradually dries, Chu Zihan's stored water is also a little insufficient.

In plants, there is a water supply balance system, which is simply the balance between water absorption and utilization.

For example, trees extract water from its roots and transport it to the leaves, which serve two purposes. The first is photosynthesis, which consumes water and carbon dioxide to produce oxygen and organic matter. The second use is plant transpiration: this water is dispersed through the stomata (not limited to the leaves) to regulate the temperature difference between the air and the plant and avoid high temperature burning, which accounts for more than 9o% of the water absorbed by the plant.

In the past, although the weather was hot, it would still rain every month or so, and with the amount of water Chu Zihan had stored at the beginning, he was also able to be self-sufficient.

But now, the weather is getting hotter and hotter, and the hottest time even reaches more than 36 degrees, plus it hasn't rained for almost a month, so the water supply is still quite tight.

Nowadays, due to the lack of water supply to the roots, the plants do not have enough water for transpiration, so many leaves have begun to wilt. In particular, the young shoots and new leaves that Chu Zihan had only grown a few months ago could no longer withstand the high temperature air around him.

Soon after, a number of leaves began to wither. In the end, Chu Zihan had no choice but to abandon the car to protect the handsome. The water is supplied to the transpiration functional leaves of the trees to ensure that the supply is kept to a minimum.

At this time, Chu Zihan's growth length had basically stopped, and the stored water was only used for basic consumption.

Originally, there should be an automatic watering system in the park, or workers would water the trees regularly every day, but I don't know what's going on, Chu Zihan has been looking for a long time underground, but he hasn't seen a damn watering system, it is estimated that it should be in the pocket of an official.

As for the workers, although they would water it once a day, he just sprinkled the water in front of Chu Zihan casually, and he didn't have to water it into the ground at all, plus the weather was so hot, just half an hour, the water would completely evaporate, and the help to Chu Zihan was basically equal to zero.

There is a small lake in the center of the park, but Chu Zihan is planted near the entrance of the park, hundreds of meters away from the small lake, and his roots are only about 5 meters away, and he is also weak.

However, Chu Zihan aimed at the ground, and his roots were now 6 meters deep.

Due to the special geographical location of Yangcheng, there will be groundwater at about seven or eight meters, which he still talked about when he heard people chatting.

In other words, if he is lucky, as long as the roots grow another 2 meters, he will be able to drink the sweet groundwater.

The premise, of course, is that there is groundwater underneath. Chu Zihan can only hope that there will be as much groundwater as possible underground, anyway, with the growth rate of his roots, it will only take a month to grow to 8 meters long.

So Chu Zihan tried his best to let the roots grow straight downward, instead of radiating to the surroundings like ordinary trees.

Half a month has passed, and during this period, there is still no progress in the search for telekinetic cells, and slowly Chu Zihan has no hope for it, but he conducts routine checks on himself three times a day in the morning, noon, and evening.

However, in terms of roots, there is good news, when the roots grow to 7 meters, I feel that the surrounding soil is a little wet, which proves that there is groundwater underneath, and after a series of calculations, Chu Zihan is expected to be able to find it about 9 meters underground.

In the past half a month, there has been another rain, and this time Chu Zihan will soon transfer the rain from the surface to the depths of the ground through the roots, increasing the total amount of available water, waiting for the next rain.

It alleviates his current predicament, but it is only alleviated, before connecting the groundwater, if the temperature does not drop, or those in high positions do not remember this park without irrigation facilities, then the fate of Chu Zihan's little sapling is really worrying.
