Back then, the Traveler took Beisht's concentrated energy blast head-on with their bare body, yet was only knocked unconscious and sustained no external injuries.
Not even their clothes were torn!
What terrifying resilience! If Lime could also acquire it, they would have new protection when facing the Electro Tribulation.
"Gawu~"
Lime trusted Yun Xu unconditionally, opening its mouth and swallowing the pill Yun Xu offered.
After losing its older sister, Yun Xu was its only reliance.
Watching Lime swallow the Four Elements Pill, Yun Xu then got up and moved a little further away, to avoid any unusual phenomena after taking the pill, such as a sudden increase in body size.
After all, Yun Xu didn't know how Azhdaha's weight would manifest in Lime; perhaps it would turn Lime into a giant dragon the size of a mountain?
After Yun Xu moved away, Lime, who had swallowed the Four Elements Pill, began to emit a yellow light.
Within the light, its body continuously expanded... expanded... then shrunk like a deflating balloon, becoming less than one person's height, and the light changed from yellow to greenish-blue.
The greenish-blue light quickly disappeared, turning pure white, and then golden.
After the golden light, all the light on Lime's body vanished, leaving only a mini-dragon in front of Yun Xu.
This dragon was even smaller than the original dog-sized Lime... Yun Xu was stunned by this sight, quickly walked over, lay down next to Lime, and gestured with his hand.
Sure enough, Lime's body length was now similar to his own, a little taller than him if you excluded the length of its ears.
It was exactly the current height of the Vanquisher of Evil!
"That's not right, it has the height, but what about the weight...?"
Yun Xu curiously reached out to try and pick up Lime, but found its body to be very light.
"..."
Yun Xu seemed to have thought of something.
The next day... "Hmm?"
Ruo Li, who had come to the doorway for some fresh air after breakfast, was suddenly picked up by the running Yun Xu.
"They're the same weight, as expected!"
Picking up Ruo Li and weighing her, Yun Xu immediately confirmed that Lime's current weight was the same as Ruo Li's.
'But its body shape clearly grew larger at first. Could it be that due to a conflict with the Vanquisher of Evil's height, it opted for Azhdaha's current weight as a secondary choice...?'
Yun Xu couldn't help but wonder inwardly.
The art of transformation wasn't just about changing appearance; weight naturally changed accordingly, which is why Ruo Li's body was as light as a child's.
Otherwise, with the weight of that mountain-like giant dragon, in her current standing posture, her two legs would probably sink directly into the ground and get stuck.
"...?"
"You scoundrel, Yun Xu, are you trying to grab a child to refine pills again?!"
Just as Yun Xu was confirming Ruo Li's weight and had forgotten to put her down, Hu Tao, who had walked out of Wangsheng Funeral Parlor, saw this scene, tilted her head, and then said with a sudden realization.
"Uh..."
Caught red-handed by Hu Tao, Yun Xu was a bit embarrassed, but after hearing Hu Tao's words, he replied as if possessed:
"No, actually, I wanted to carry her to bury her."
"???"
Ruo Li, who was originally a bit bewildered by being picked up, seemed to have question marks pop up above her head upon hearing this, and immediately struggled twice, escaping from Yun Xu's arms.
"Zhongli, someone wants to bury me!"
Ruo Li, having escaped, scurried back into Wangsheng Funeral Parlor.
"Don't tell me, this scene really does look a bit like Qiqi running to find Baizhu."
Seeing this, Hu Tao stood beside Yun Xu, stroking her chin and muttering.
"Then hurry up and run, otherwise you'll have to write another letter of apology."
Hearing Hu Tao say that, Yun Xu turned around without a word and ran back home.
"Then where should This Master run?"
Hu Tao looked at Yun Xu's house, then at Wangsheng Funeral Parlor, and finally decided to go back and take a look.
Anyway, it wasn't her who said she wanted to bury Ruo Li... After taking the Four Elements Pill, Lime began to show some strange reactions over the next month.
Because its body length was dozens of centimeters shorter than before, it now didn't even have the size of a dog, which allowed it, despite being a Thunder Dragon, to drape itself on Yun Xu like Changsheng on Baizhu.
And after becoming this size, Yun Xu also felt that taking it out wouldn't attract too much attention, so he began to take it out appropriately.
The first time he took it to Bubu Pharmacy, Changsheng even thought Yun Xu was imitating Baizhu, and then taught Lime, who was on Yun Xu, in the tone of an experienced elder.
Besides that, Yun Xu found that Lime no longer liked to eat electro crystals, but wanted to eat normal human food, perhaps influenced by Paimon's appetite.
However, even though Yun Xu prepared a lot of delicacies for it, it would sometimes become listless, curling up its entire body, and barely reacting to Yun Xu's calls.
And the sharp horns on its head also began to discharge electricity irregularly, with varying power; at low power, it gave Yun Xu a jolt, and at high power, a bolt of lightning struck, leaving a black crack on the streets of Liyue Harbor.
This made Yun Xu suspect it was sick. After feeding it Sweet Sweet Pills proved useless, he had no choice but to take it to Bubu Pharmacy to ask Baizhu for help.
But Baizhu couldn't figure out the reason, instead, Changsheng gave a hint.
"This little fellow's illness is related to elemental power. You might need to invite an expert who is very skilled in elemental power to take a look. Baizhu can only prescribe a refreshing medicine for you, but its effect won't be very significant."
Changsheng explained this to Yun Xu.
"I see..."
Yun Xu nodded, then left Bubu Pharmacy with Lime.
Looking at the listless Lime in his arms, and the sharp horns on its head that occasionally flashed with electric arcs, Yun Xu quickened his pace.
Finally, Yun Xu found Zhongli, who was watching a play at the Heyu Tea House.
"Emperor, help! My dragon seems a bit depressed. Is it going to die?"
There were many people here, so Yun Xu could only quietly ask Zhongli for help.
Hearing Yun Xu's distress, Zhongli had heard enough of the play, so he nodded and agreed.
Leaving the Heyu Tea House, the two found a quiet place, and only then did Zhongli examine Lime's condition.
After some examination, his eyebrows furrowed, a rare sight.
Seeing this, Yun Xu's heart skipped a beat.
He had long regarded Lime as his pet, loving it more than his own tail.
"This situation... a deficit in Electro elemental power... perhaps there's only one explanation."
After a long silence, Zhongli finally spoke.
However, seeing Yun Xu's expression of wanting to press further, Zhongli had no choice but to continue:
"Have you ever heard that Elemental Dragons are the pinnacle of evolution for all elemental life?"
Facing Zhongli's question, Yun Xu nodded.
After all, the earliest batch of Adepti were pure elemental lifeforms, and this was common knowledge for them. As an Adeptus disciple, Yun Xu had also heard Cloud Retainer speak of it.
"Indeed, and this pinnacle of evolution, limited by Teyvat's own rules, can only exist as one at a time."
Seeing Yun Xu nod, Zhongli responded and continued to explain.
"As long as Azhdaha is not dead, even if the Geovishaps absorb the power of the ley lines for tens of thousands of years, they are destined to be unable to evolve into a new Azhdaha. The same applies to the Thunder Dragon."
"But perhaps your pill broke the limitations of heaven and earth. It began to evolve towards becoming a Thunder Dragon, but there is no second authority of the Thunder Dragon in this world, so its evolution is destined to remain in the pre-completion stage."
"Unless you can find the Thunder Dragon, wherever it may be in Teyvat, and kill it to seize its incomplete authority, otherwise it is probably... incurable."
