The sharp needle pierced into the skin, and the diluted light - golden potion with only 50% content was slowly injected into Yan Yincheng's body bit by bit.
After the injection, there would be a five - day observation period.
This time when Yan Yincheng participated in the clinical trial, the three - stage treatment would take a total of two months. During these two months, as the maker of the potion, Xu Zixi would stay by his side all the time, observing his condition and making adjustments according to the experimental data at any time.
The glandular fluid of the "Golden Amber" contained highly active molecules that could compensate for genetic defects. Therefore, in the middle of the night after the injection, Yan Yincheng developed a high fever.
Reaching out to touch his burning forehead, although Xu Zixi knew that this was the impact of the changes in cells and genes, a natural reaction that every patient would go through.
However, seeing Yan Yincheng's uncomfortable appearance and listening to his heavy breathing due to the high fever, Xu Zixi felt extremely heart - broken.
Wiping the tears off her face, Yan Yincheng smiled and said, "Just hold on for a while longer, and I'll be able to see what you look like with my own eyes. I really want to see what you look like when you cry. Miss Xu Zixi with single eyelids, small eyes, a flat nose, buck teeth, a short stature, and O - shaped legs?"
Hearing his description, Xu Zixi couldn't be sad anymore. She burst out laughing and couldn't help but punch his shoulder.
"Then you'll also see what you look like, Mr. Yan Yincheng with upturned eyes, a bulbous nose, an underbite, baldness, and a beer belly."
"I didn't expect that even such a me could fascinate you so deeply." Yan Yincheng laughed. "Miss Xu Zixi has really unique tastes."
Xu Zixi lay on his chest, listening to his steady heartbeat, and said, "So, a well - matched pair like us must be tied together forever, looking at each other until we're sick of it."
Hearing the steady breathing of the woman beside him after she fell asleep, Yan Yincheng hooked the corners of his mouth and smiled.
Get sick of it? How could that be? He wouldn't get enough even if he looked at her for several lifetimes.
The high fever on Yan Yincheng gradually subsided on the third day. After another two days of observation, his feedback was that all his physical functions were in good condition, and even his five senses had become a little sharper than before.
The first stage of the treatment was over, and there was a three - day recovery period. After the recovery period, Yan Yincheng started the second stage of the treatment.
This time, the concentration of the injected potion increased to 75%. The color of the potion was darker than before, and Yan Yincheng's eyes needed to be treated with eye drops three times a day, morning, noon, and evening, and his eyes were wrapped with gauze.
With the increase in the potion concentration, the speed of cell division and gene change in the patient's body increased by 1.5 times compared to before. The high fever of Yan Yincheng lasted longer than in the first stage, and he also suffered from vomiting, bone pain, coughing and other symptoms.
He was tortured by these reactions and lost a lot of weight. His facial features became even more sharp.
But the good news was that under the dual treatment of the potion injection and the eye drops, his eyes could already sense the change of light. However, due to his long - term blindness, such a change would make his eyes sting and shed physiological tears.
When Xu Zixi learned that he could sense the light, she was extremely excited. She held his face and kissed his eyes wrapped in gauze again and again.
On the ninth day of the second - stage treatment, the dark blue in Yan Yincheng's eyes completely faded, and a thin film with a faint gray color covered his pupils.
Xu Zixi knew that it was a membranous substance automatically regenerated by the eyes after the genetic defects were gradually repaired. When all the treatments were completed, this membranous substance would automatically fall off completely, just like the molting process of many amphibians and reptiles.
After the second stage ended, there was another three - day rest period, and then Yan Yincheng entered the third stage of the treatment.
The 100% - concentrated potion, a golden - yellow liquid almost the same as the glandular fluid of the "Golden Amber", was injected into Yan Yincheng's body. Next, he would enter a fifteen - day healing period.
The gauze in front of his eyes had been removed. He needed these fifteen days to feel and adapt to the feeling of his eyes gradually regaining their sight until he could see completely.
After the second stage of the treatment, Yan Yincheng could already sense the intensity and change of light. Just thinking that he might be able to fully recover his eyesight in fifteen days made him extremely excited.
At this stage, his body had completely adapted to the pathological changes caused by the potion injection. Although his bones ached all over and he felt nauseous and couldn't eat every day, every morning when he opened his eyes, he could clearly feel the changes in his eyes.
The gray film on his eyes was slowly becoming thinner and lighter.
He gradually changed from only being able to sense the intensity and change of light to being able to see a faint shadow of objects.
At first, these shadows were only in black and white. But this was already enough to make him and Xu Zixi excited.
On the sixth day, those vague shadows began to have colors.
The feeling was extremely wonderful, as if someone was in front of him, using a paintbrush to color his monotonous world bit by bit.
Xu Zixi would push Yan Yincheng to the park near the hospital for a walk every day. Holding his hand, she was like a very patient teacher, teaching him to recognize the colors in the world.
Red was hot and festive.
Green was lush and vibrant.
Blue was broad and steady.
Yellow was bright and active.
And there were also purple, pink, orange...
He studied extremely hard, only hoping that at the moment when he fully recovered his eyesight, he could engrave her appearance deeply in his heart.
During the third - stage treatment, Bai Xuanhe and Alex, who had been missing for a while, returned to Fengcheng. The two of them also joined the clinical trial, helping Xu Zixi. They would often follow far behind Xu Zixi and Yan Yincheng and go for a walk in the park together.
After learning what they had done from Yuan Ya'er, Xu Zixi no longer felt so resistant to Bai Xuanhe and Alex. Occasionally, when she prepared food for Yan Yincheng, she would also bring a share for the two of them.
After all, according to the original story plot, Bai Xuanhe would become Yuan Xi's most powerful assistant, and they shouldn't be enemies.
Moreover, if it weren't for Alex back then, Yuan Xi would have been defiled by Guan Baocheng, and Yuan Xi's ending would only have been worse. At least because of Alex, there were such lovely kids like Xuanxuan and Xuxu.
How could there be so much hatred in this world?
The relationship between people should never be defined by a single pattern.
One day, the weather in Fengcheng was very nice. After entering summer, the temperature suddenly soared, and there were cicadas singing everywhere. In the evening, Xu Zixi took Yan Yincheng's hand again and came to the Riverside Park to relax with him, Bai Xuanhe, and Alex.
The hot weather made all four of them sweat by the time they walked to the bench under the tree.
Alex sighed, "It would be great if we could have an ice - cream at this moment."
Yan Yincheng was quite tempted. "Ice - cream? I've never eaten it."
His five senses were too sensitive, and ice - cream was both cheap and overly sweet for him, so it had never been his choice. However, after falling in love with Xu Zixi, he had tried popcorn and cola, which he had avoided before, and the taste wasn't completely unacceptable to him. So, he was now interested in ice - cream.
Xu Zixi smiled and ruffled the hair on his forehead. "You guys wait here. I'll go buy some. I'll be back soon."
After saying that, she turned around and trotted away.
Yan Yincheng could only see that in a hazy colorful halo, his woman was skipping further and further away.
Although his eyes hadn't fully recovered, he stubbornly faced the direction she left in, chatting casually with Bai Xuanhe and Alex beside him, waiting for Xu Zixi to come back.
Suddenly, a gust of wind blew from under the tree, and something got into Yan Yincheng's eye. He only felt extremely uncomfortable in his eye and couldn't help but close his eyes and roll his eyeballs, trying to let the foreign object flow out of his eye with his tears.
It wasn't until the discomfort in his eye completely disappeared that he opened his eyes again.
At this moment, his world became clear.
He saw the deep - blue sky and the fiery red clouds, the green grass and the lush big trees that provided shade for them, and the golden sunlight that covered the entire ground.
And a girl skipping towards him.
