The pulse in the palm of his right hand was so clear. Cheng Lin tried his best to calm himself down and walked towards the single-family dormitory area without revealing any flaws.
He was originally going to have a meal first, but now, he no longer has that intention.
…
Dormitory area.
He walked upstairs to the familiar door, took out the key, opened the door, and used his superpower to make sure there were no prying eyes around him. Then he stood in the living room of the dormitory and raised his right hand slightly.
In a flash of light, the door appeared silently in front of my eyes.
The height of the room is limited, so the door does not open too wide.
"I don't know what the upgrade will look like. The space must be expanded a lot. I'm afraid there won't be enough soil, so I have to find a way to steal more soil."
Cheng Lin took a step forward and entered the spiritual world.
…
Within the spiritual world.
As soon as he landed, Cheng Lin felt a breeze blowing towards him.
He subconsciously took a breath. The air was moist and clear, like the morning after the rain, making his whole body feel much refreshed.
"Huh? No, why is there wind?"
But he soon realized something was wrong. There was no wind in the spiritual world before. Because there was no sun in the previous spiritual world, the light source was all provided by the World Tree, so the temperature was always constant, which resulted in a very stable air flow.
This is obviously no longer the case.
Thinking of this, Cheng Lin immediately raised his head and looked at the sky, his eyes widening.
"This is……"
He was surprised to see a "sun" hanging in the sky!
Yes, not only that, but there are also blue sky and white clouds, just like the outside world, only it is clearer than outside!
"How could these evolve here?"
Frightened, he took a closer look and suddenly saw something strange.
"No, that's not the real sky and sun, but more like... a painting?"
Yes, the "sky" above his head is flat, like a dynamic sky wallpaper, which is pasted on the top to have a similar effect.
This is amazing.
And that wasn't the only thing that surprised him.
Cheng Lin lowered his head and looked at the spirit world, and found that the space had expanded greatly as expected. The original spirit world was about fifty meters long and wide, and about twenty meters high. Now, according to visual inspection, the length and width are two to three hundred meters.
Meters! The height is also over 100 meters!
Roughly converted, it is approximately equal to the area of 4-5 football fields.
This is very impressive.
What surprised him the most was that such a large area was actually filled with soil, grassland to be precise.
Looking around, it looks like a grassland.
"Where did the soil come from? Could it be that it came with the upgrade? Or was it made by the World Tree?"
Confused, he finally looked at the World Tree. Sure enough, it had become even bigger, with a height of more than a hundred meters, almost touching the limit of space. The whole tree exuded infinite vitality, and its branches radiated in all directions.
A little prototype of the world tree in the elf world.
On the dense canopy of trees, the branches and leaves are fresh green and glowing, as if it had just rained.
When he looked over, a shadow flew out from the tree crown, chirping, and flew in front of him.
It's Ciri.
It seemed to be very excited, and it didn't look like it was afraid, but more like it was incomprehensible and amazed after witnessing the great changes.
"It's rare but strange." Cheng Lin glanced at it and said with a chuckle.
I immediately went to check my belongings and found that the problem was not big, there was no damage, but the bed was wet.
He breathed a sigh of relief, walked towards the World Tree, and then stretched out his hand to touch the trunk.
There is a "panel" in front of you:
Name: World Tree (Level 4)
Experience:5034/10000
Condition: Good
Reminder: The Level 4 World Tree has a certain ability to transform the environment. It can use existing materials to improve its living environment, including: soil, vegetation, air, rainwater, etc., and cooperate with the "spirit world" to a certain extent.
Simulate weather.
…
"It's true." Cheng Lin saw clearly.
The level 4 world tree can actually create soil? Well, judging from this explanation, it should not be created out of thin air, but based on existing soil.
Theoretically, soil is just a collection of elements. Although the creation of soil sounds very fantastic, the world tree cannot be speculated using common sense.
"According to the instructions, is this now a self-circulating system?"
He remembered that the spiritual world had reminded him that if there was a shortage of water, it would need to be replenished from the outside world.
In fact, Cheng Lin did find opportunities to add this during this period. It was very simple, just find a river and open the entrance to the spiritual world in the river.
Every time I add a little bit, because the area is not big, there is no problem.
This reminded Cheng Lin of the famous "Biosphere 2".
All in all, it is more like an independent world although it is still small.
As for the concentration of spiritual energy... Cheng Lin felt it based on experience and found that it was around 7,000, which was slightly lower than he expected. It seemed that most of the spiritual energy had been swallowed up by the World Tree...
This made Cheng Lin feel resentful: "Can't you leave more for me?"
But this actually made him very satisfied. Even the No. 16 spiritual land could not exceed the 5,000 standard. Even if the concentration here was not as good as the top spiritual lands in the country, it could still be among the first-tier.
"I just don't know if I can keep it, but don't suck it and lose it."
While he was thinking about it, he suddenly heard Xirui chirping next to him, flying around in front of his eyes, and then flying back around the tree trunk, as if... letting him see something.
"Are there any changes?"
Cheng Lin frowned and followed Xirui to the "behind" the World Tree. He immediately paused and had a look of disbelief on his face.
I saw a "tree hole" appearing on the trunk of the tree.
The tree hole is not deep, only about two or three meters. At the end of the tree hole, there is a small "light door", which is oval in shape and emits a faint shimmer.
At the same time, Cheng Lin felt his phone vibrate in his pocket.
He quickly took it out and found that it was a blank notification that popped up on the notification bar. He clicked on it curiously and jumped to the "Deduction Program App". After loading it for a while, he opened the "History Library" page.
Among the string of dark gray "historical deduction" cards, the edge of the only card pointing to the elf world exuded a soft green light.
"Is this..."
He clicked the screen with a slight trembling, and saw a dense text popping up on his phone.
Cheng Lin lowered his head and read carefully, word by word, paragraph by paragraph, and his breathing became rapid.
This is an explanation.
His guess was correct. After the elf projection ended, the "not yet open" that appeared could finally be opened!
"According to this explanation, the passage to the elven world has been opened. I can decide to open or close it independently. However, the passage does not seem to be very stable at present, so it cannot allow creatures above the intermediate level to pass..."
Putting down his cell phone, Cheng Lin stared at the "tree hole" in front of him, his eyes glowing with a strange light.
He had already made many speculations about this function, but he never thought that it would be implemented in this way.
"It seems that the reason why the elf card was lit is probably related to my obtaining the World Tree Seed. It is the basis of the bridge connecting the two worlds. However, its level was too low before, so this function was not turned on."
"There are restrictions on the passage of intermediate-level creatures and above? Doesn't this mean that I can't enter?"
Cheng Lin tentatively walked into the tree hole and tried to enter, but felt a strong resistance.
"It seems that I can't go in," Cheng Lin felt a little regretful, then thought, "The tree cave is restricted to the middle level, which is converted to the fourth level. Now the world tree level is level 4. Are the two related? No.
Too sure, maybe there is, maybe not, but it is possible after all, that is to say, as long as I continue to upgrade the World Tree, it is possible to strengthen this passage."
After a brief analysis, Cheng Lin had an idea.
However, it is not easy to increase the level of comfort. The higher you go, the more "experience" you need to upgrade. You may find a way to gather the materials for the spirit gathering ceremony, but the opportunity is hard to come by.
This time it took Longdao countless years to achieve such effectiveness. I don’t know when the next similar opportunity will come up.
Shaking his head and thinking no more, Cheng Lin began to analyze the possibility of using this passage.
The first idea was to ask the elves to help build the spiritual world.
Nowadays, the area of the spirit world has expanded a lot, but the infrastructure is not perfect. Large areas of land are abandoned. Elves may be hired to cultivate them, and even spiritual plants and grass can be purchased from the elves world.
Thinking of this, Cheng Lin's heart surged.
"The first thing is to make contact with the other side."
He first tried to use his "synaesthesia" power to touch the channel, but found that it was still blocked, indicating that the power could not pass the boundary.
"Perhaps you can write a letter and throw it over, but if the other party doesn't know the situation, it's still too risky."
Cheng Lin thought seriously and frowned.
Suddenly, he saw Ciri combing her hair on a nearby branch, and then his eyes lit up.
"Yes, I entered the middle level and couldn't get in, but Ciri is so useless, she should be able to enter the passage, and it has a certain intelligence and is convenient for doing things. The only question is whether it is reliable and whether it can directly
Ran."
Cheng Lin thought about it carefully and suddenly came up with an unlikely idea.
After a slight hesitation, he returned to his locker, tinkered with it for a while, then walked back and stretched out his left hand: "Come here."
Not knowing why, Xi Rui flew into his palm, and immediately saw Cheng Lin tying a paper roll tied with a string to its leg, and then pried open Xi Rui's beak with his right hand like lightning, and pulled out a paper roll tied with a string.
A small pill is inserted into its esophagus.
"What I just fed you was a poison. If you don't take the antidote within 72 hours, your stomach will rot and your intestines will turn into a puddle of pus and die.
Don't look at me like that. Please help me send this letter to the other side.
Well, when you encounter a particularly beautiful creature that resembles a human being, you will give this letter to that person. It is best if you can bring back a reply from the other person.
Then I will give you the antidote, and if everything goes well, I will also give you a reward, do you understand?"
Cheng Lin calmly narrated.
Xirui was completely stunned. She looked at Cheng Lin and then at the "letter" on her feet. She realized that this evil "farmer" had used her as a homing pigeon. She couldn't help feeling sad, but she still nodded.
"Very good, then set off immediately. I'll wait for your triumphant return."
Cheng Lin nodded with satisfaction, and then threw Xirui directly into the tree hole.
With a swish, it disappeared into the passage.
…
