After trying a few more times, Gu Shi simply reached out and picked up the silver cup, wanting to pour the contents into his palm.

This silver cup is not big, its capacity is similar to that of an ordinary small wine glass, and there doesn't seem to be much liquid in it, so it can be held in one hand.

As a result, not only did Gu Shi's pouring cause the liquid to flow all over his palm, but some of it also accidentally overflowed.

"Oh, no!"

Gu Shi looked at the water droplets scattered on the ground because of his previous actions with some annoyance. He didn't expect that in addition to the liquid inside, this silver cup was not as simple as it seemed.

The liquid in Gu Shi's palm alone was enough to fill a cup of the same size. However, after pouring out so much liquid, the water level in the silver cup did not change at all.

No wonder it can support the vine snake to grow so big. Gu Shi was just wondering why the amount of liquid was so small. It turns out that the capacity of the silver cup is more than what it looks like.

Gu Shi took out a bowl from the space ring and poured the liquid in his hand into it. Only then did he have the mind to observe the liquid that flowed to the ground.

The water droplets were immediately absorbed by the vines after they dripped onto them. The effect of the liquid was immediately apparent on the vines. Not long after, the vine under Gu Shi's feet became visibly thicker and greener.

Seeing such an obvious effect, Gu Shi's eyes lit up, and he already assumed in his heart that this was what Isidore said, the thing that could help him change into a tree shape.

However, Gu Shi still searched other places in the temple again, and only came to a final conclusion after confirming that there were no other suspicious objects inside except this silver cup.

Gu Shi walked out of the temple slowly with the silver cup in his hand. He was a little hesitant whether to try to transform right here.

Gu Shi thought about it carefully and decided that this was indeed a good place. There was no danger and he didn't have to worry about being disturbed by others.

Moreover, he was not sure whether he could change back smoothly after transforming. If he went back to try, what if he couldn't change back for a while and was discovered by others?

Gu Shi had no reasonable excuse to explain why he suddenly turned from a human into a tree, so he might as well try it directly in this deserted underground cave.

After considering it for a while, Gu Shi made up his mind, "Let's try it here first."

"But how do you use this? Do you drink it directly?"

Gu Shi was a little hesitant. Judging from the performance of the vines just now, they absorbed the liquid directly through the epidermis. And its prototype was a tree. Did it have to use this liquid to soak its feet?

Gu Shi shook his head and silently rejected this idea. It sounded too unreliable.

Gu Shi sat down on the steps in front of the temple, placed the silver cup beside him, and then took out the bowl he had just used to hold the liquid that had been poured out.

After adding some more liquid, Gu Shi immersed most of his hand in it. After about ten minutes, he took his hand out.

Gu Shi looked at the liquid in the bowl and found that it had not decreased. It seemed that this approach was wrong.

After trying to absorb it through contact without success, the only option left is to drink it.

Gu Shi wiped the edge of the silver cup, then carefully brought it to his lips and took a sip of the liquid inside.

It felt icy cold as before when it entered his mouth. Gu Shi didn't taste anything. The liquid was like jelly made of water and quickly slid down his esophagus into his stomach.

After taking the first sip, Gu Shi waited silently for a long time, but did not notice any changes in his body.

Gu Shi speculated with some doubt, "Could it be that I didn't drink enough?"

Thinking of this, he took several more sips.

This time, Gu Shi finally had a little different feeling, but it was not a sign of transformation, but his body was urging him to drink more, drink more.

Gu Shi naturally would not ignore the reminder given by his body. He obeyed this desire and continued to drink from the silver cup in big gulps.

Gu Shi didn't know how much liquid he drank in the end. Anyway, as he drank, he felt the magic power in his body surging and then running rapidly on its own.

The next moment, Gu Shi put down the silver cup with a sense of realization, and his whole body began to emit a bright green light.

In the underground where no one knew, Gu Shi's figure was constantly changing.

When the turquoise light completely faded away, Gu Shi was surprised to find that his perspective had actually become shorter.

Gu Shi was just about to reach out and rub his eyes, but he found that two branches with tender leaves rose in front of him. He waved his hand again uncertainly.

"Is this a success?"

After seeing that the branches in front of him were indeed swaying according to his wishes, Gu Shi was sure that he had turned into a small tree.

Gu Shi tried to judge from his current perspective. He was only about half of his human height, less than one meter!

Gu Shi sighed helplessly, "No wonder Isidore said I was still a sapling. I thought he was exaggerating, but it turns out I really am a sapling."

After turning into a sapling, Gu Shi suddenly felt a little thirsty, so he wanted to walk over and get the silver cup beside him. However, as soon as he took a step, he tripped and fell straight to the ground.

Gu Shi cried out in pain: "Hiss, what is that? It hurts so much, it feels like my hand is broken."

When he fell just now, he subconsciously used his hands to support himself on the ground, but his fragile branches could not withstand such a toss and turn, and one of them broke.

Gu Shi lay on the ground for a while and continued to move after he felt the pain was less severe.

Gu Shi struggled to get up from the ground. The body of a tree was far less flexible than that of a human. He rolled on the ground for a long time before finding the right angle to stand up.

Looking at the broken branches and green leaves on the ground, Gu Shi couldn't help but feel distressed. He was still young and didn't have many branches and leaves to begin with. Now so many of them had fallen off unexpectedly. Wouldn't he be bald when he grew back?

After lamenting his loss, Gu Shi turned around to see what had tripped him, and saw clothes scattered all over the ground.

???

Gu Shi was stunned at first, then he realized that those were his clothes.

"The clothes didn't change with it? That's right, if they did, that would be abnormal."

Gu Shi thought about it. If his clothes also transformed along with him, wouldn’t they become tree bark? That would be hard to explain. After all, who can change their tree bark every day?

After learning this lesson, Gu Shi paid special attention to his feet when he moved. He moved his roots little by little and finally reached the edge of the silver cup.

Now that he had turned into a tree, it was naturally impossible for him to drink water in the same way as before. Gu Shi tried to control one of his roots to reach into the silver cup, and then it began to automatically absorb the liquid inside.

Gu Shi's thirst was finally relieved.
