The world cannot ascend to heaven or earth, so they do not know how high the heavens are and how thick the earth is.

The world does not see those who can still survive and reappear after falling off the Yin-Yang Bridge, so they don't know that there are thousands of miles under the Yin-Yang Bridge, and there are streams and valleys in the depths of thousands of miles.

The river is nameless, the valley is nameless, and the cold charm calls the valley as the valley of yin and yang in the name of the yin and yang bridge.

In the past year and a half, Leng Mei has set foot in a radius of more than 100 miles, blocked in front of the cliff, trapped in the bamboo forest, and has not seen the road out of the valley, let alone the second living person.

In Leng Mei's view, the Yinyang Valley is not inferior to Baihuayu, she even suspects that the Baihuayu that the world sees is only the side of the Yinyang Valley that the world is willing to show to the world, and the bridge is the most real world of Baihuayu, and the Yinyang Bridge is not separated by life and death, but two worlds, one is Baihuayu bordering the world, and the other is the Yinyang Valley isolated from the world.

Isolated from the world, there must be a difference.

In the Yin Yang Valley, there are only spring and summer, and there is no autumn and winter, the grass and trees have not withered and have spit out new branches, and the flowers have not withered and have added new buds.

At present, the bridge is still in early spring, and there are lotus leaves under the bridge.

In the blue pond on one side, a hundred red lotus flowers reflect the sun, which is very beautiful, and although a few green lotus flowers like bamboo are also in full bloom, they are mixed with the green lotus leaves and are inconspicuous.

But this inconspicuous Qinglian is Jiang Yichen's hope for regaining his sight.

The poison that blinded Jiang Yichen was the Blind Sand, the essence of the Blind Sand was poisonous Gu, this poisonous Gu worm was extremely tiny, difficult to see with the naked eye, and lived on colloidal substances, with a life cycle of only ten days, but it could multiply tens of millions of times in a short period of time, and thousands of Gu worms gathered into a swarm like flowing black sand.

The essence of the human eye is colloid, and it is also the thing that the sand worm likes to eat, so once it attaches to it, the Gu worm will multiply on the surface of the eyeball.

In the initial stage, Gu worms were active in the most superficial layer of the eyeballs, and as the Gu worms continued to multiply, the number was hundreds, thousands, tens of thousands, hundreds of thousands, millions, and the entire eyeballs were covered by a swarm of black Gu worms like a dark cloud, and they no longer saw their brilliance.

It is not until there is no room left on the surface of the eyeballs that the Gu insect swarm will stop conquering and fall into a dormant period.

This dormant period lasts for about eight or nine days, and most of the Gu worms are about to die, waiting for death to come, while the few Gu worms born a little later have not yet had a full stomach and have not yet multiplied enough offspring, and are unwilling to die, so they will open up new food sources.

The superficial layer of the eyeball is already occupied, and the new food source comes from the inner layer of the superficial layer.

In the new stage, the reproduction rate of Gu worms is slightly slow, and every birth of new Gu worms will be accompanied by the death of some old Gu worms, until the inner layer of eyeballs is wrapped by a new Gu worm swarm again, and the reproduction of Gu worm swarm will stagnate and enter a new round of dormancy.

The size of the eyeballs is always limited, and the Gu insect swarm is getting smaller and smaller from generation to generation, but the generation after generation of Gu insect swarms will eventually eat up the entire eyeball.

Compared to blindness, endless torture is the most cruel and vicious curse of the Nayi tribe against the Baili tribe.

It may be difficult for a single Gu worm to bite on the eyeball, and ten Gu worms can only feel the feeling of mosquito bites when they eat, but the Gu worms reproduce so fast that it will not take long for people to realize what it means to pierce the eyes like needles!

When the Gu insect swarm sprinted to the last pure land on the surface of the eyeballs, the pain was like the stinging pain of thousands of silver needles piercing the flesh only gathered in the eyes, this pain did not flow on the surface of the body, but was deeply and directly directed into the nerves of the brain, and the most acute place of pain was to teach people to live in pain, and to teach life to be worse than death!

It is not easy for people to survive such pain once, let alone most people who can't bear such pain at all, and most of them go straight to self-consciousness in the process.

And if you have to suffer such severe pain every ten days, even if you have a tough heart, you will not be able to resist the double torture that comes from both physical and mental torture.

In the past, few people in the Baili tribe who were poisoned by the blinded sand could survive until their eyeballs were swallowed up by Gu worms, or cut off their own eyes, or cut off their eyes by means of self-harm, and survived for the rest of their lives.

At that time, the reason why many martial arts masters and the world's divine doctors were helpless was because in addition to feeding on the eyeballs, the Gu worms also had a strong survivability, which could not be washed away with ordinary potions, and could not be forced out with strong skills, and only by wiping with external forces could they get rid of a little, but this move would not cure the symptoms, and the vacant parts would not be occupied by the rapidly multiplying Gu worms in a short time, just adding a pain.

But just like the facts that happened a hundred years ago, the story Leng Mei said, there is no endless road to heaven, and one thing descends to another.

Gu insects feed on colloidal things, so they can use the method of booby-trapping to lure out Gu insects with a colloid that is more delicious than eyeballs, and then kill them!

Out of the mud and not stained green lotus, petal slices boiled water has the effect of dispelling poison and brightening the eyes, lotus seeds decoction in the spleen and stomach is beneficial, nourishing the heart and calming the nerves, and if the petals and lotus seeds are mixed together in a slow fire for half a day, crystalline colloids will be born.

This crystalline colloid has no practical medicinal value, but as long as it can make this colloid "delicious", it is a good medicine for the treatment of blindness.

In the past, the prescription stewed this crystalline colloid and more than a dozen kinds of herbs for several hours, and the cooled crystalline colloid was crystal clear, which was naturally very different from the eyeballs, but in the eyes of Gu insects, it was a precious tonic.

As long as this lens colloid is applied to the eye and the colloid is slowly absorbed by the eye, these colloids will become a new food source for the Gu insect swarm and stop further damage to the eyeballs. Once the Gu worm swallows these "delicacies" into its stomach, it is also the time of its death, and the food and poison are one!

When the Gu worms are completely eliminated from the surface of the eyeball, applying a new clean colloid will replace the lost lens of the eyeball, and over time, the colloids will be co-transformed by the eyeballs.

Therefore, the dosage of colloids in the repair stage is very particular, less will affect the distance of vision in the future, and more will cause long-term swelling and pain in the eye holes.

On the day of the fall, the blinding sand had completely eroded Jiang Yichen's eyes, and he was in the first dormant period of the Gu insect swarm during the five days of coma.

Leng Mei couldn't recall all the contents of the prescription she had seen many years ago, only the specific description of the colloidal representation on the prescription that was finally refined, and she used this to determine the success of the results of repeated attempts to dispense medicine.

Finally, after she tried it more than 30 times, that is, the day Jiang Yichen woke up, she determined a colloidal prescription that she was 60% sure of, and then began to treat Jiang Yichen's eyes the next day.

Xu is Gu insect swarm is in the dormant period, Xu is Leng Mei's Qinglian colloidal effect is limited, Xu is Jiang Yichen's perception of the eyes is too numb, all in all, on this day, Leng Mei changed the medicine for Jiang Yichen three times, Jiang Yichen didn't feel anything wrong with his eyes, and he couldn't give feedback to Leng Mei whether it had improved.

On the seventh or eighth day after that, which was also the third or fourth day after Jiang Yichen woke up, Jiang Yichen couldn't help but tense his nerves, waiting for the severe pain brought by those Gu insect swarms after they passed the first dormant period.

How did you know that the Gu insect swarm allowed Jiang Yichen to spend two days peacefully in uneasiness, and it was dormant for nine full days before it completely broke out!

......

......

The pain came at dawn.

Last time, Jiang Yichen was unconscious when he fell off the bridge, so he escaped the pain.

This time, Jiang Yichen greeted this baptism when he was most sober.

After experiencing the suffering of the Ten Thousand Poisonous Graves, the sharp pain of a thousand needles piercing the eyes naturally failed to break Jiang Yichen's spiritual defense, but it did not mean that his physical strength and nerve strength could completely ignore the strong stimulation brought by those pains.

Although he didn't say a word, the pain forced out layer after layer of sweat, and his clothes were soaked early.

The pain lasted for two hours, so that the cold charm who had made up his mind to wait and see what happened felt wrong, thinking about what was wrong with the medicine, but he didn't dare to act blindly.

In the end, although Jiang Yichen resisted the pain, he fell asleep due to the exertion of his mind.

Seeing Jiang Yichen who was sleeping deeply, Leng Mei couldn't help but recall the past he had told him in the past few days, and two emotions flashed in his eyes, one was understanding and the other was admiration.

Leng Mei admired Jiang Yichen because she didn't think that she could make a better choice in a short period of time in the things he was going through.

Leng Mei understands Jiang Yichen very well, and feels that when they are on the Yin-Yang Bridge, they are basically the same kind of people, and the people close to them treat them very well, but this world is destined to not allow them and their relatives to spend the rest of their lives in peace, so they gradually became a chess piece of sufficient weight under the expectations of others and with their own efforts.

But the chess pieces are chess pieces after all, and at worst, they are just a tool with feelings, and the people close to them will be angry and angry because of the loss of their chess pieces, but they will not stop moving forward for them after all.

And when two temporarily abandoned and forgotten chess pieces meet unexpectedly, there is no reason to feel a sense of sympathy, and she will definitely help him!

After being stunned for a long time, Leng Mei took off the lotus leaf wrapped around Jiang Yichen's eyes, turned over the side coated with green lotus colloid, and after contemplating for a while, it was fruitless, and followed the sunlight that had already been hidden by the window and door but was getting brighter and brighter, and slowly walked out of the house, sighing.

She knew what the problem was, and she knew better that she couldn't solve it perfectly.

After all, no one can pat their chests and guarantee that the articles that they glanced at casually out of curiosity a few years ago will be remembered word for word until now.

She frowned, and looked at the lotus leaf in her hand again with some distress.

I saw that the viscous colloid, which was still crystal like dew drops last night, was reflecting the sunlight at this moment, and it was dazzling and abnormal.

Although the glow was dazzling, under the abundant light, Leng Mei finally saw a thin line of black spots floating between the lotus leaf textures that had been cleaned cleanly!

Leng Mei's heart moved, and she carefully picked up the lotus leaf and approached it, looking at it more carefully and carefully, and repeatedly determined that the thin line formed by the black spots was definitely not some dirt impurities, but similar to a little bit of fine black sand, the jade lips opened lightly, and breathed a sigh of relief!
