The atmosphere in the imperial study was extremely depressing, and even the slightest disturbance could be heard clearly.

Wei Qingguan walked slowly and methodically in the direction of the dragon case.

Ou Yu knelt on the ground, and when he saw her, he couldn't help but bow down and retreat, he didn't dare to disturb Wei Qingguan and Ye Tianling.

Ye Tianling's eyes were like knives, staring straight at Wei Qingguan.

"Wei Qingguan, it's time for you to keep your promise!"

On that day, Wei Qingguan met with Ye Tianling and confessed that she could cure Ye Tianling's hidden illness, but the premise was that she had to get rid of those who harmed her.

Ye Tianling was a little hesitant at first, but after knowing what happened to Wei Hongda in the past, he didn't hesitate at all.

Wei Qingguan's slender and white hands took out a porcelain bottle from his sleeve and handed it to Ye Tianling.

"Regent, courtier, judging from your explanation, you have night blindness, and as long as you take the medicine given to you by your courtier, your condition will be alleviated."

Night blindness is mainly caused by vitamin A deficiency.

Wei Qingguan put vitamin A tablets in a porcelain bottle before coming, which happened to be given to Ye Tianling.

The reason why Ye Tianling has night blindness is because of years of fleeing, sleeping in the open air, and malnutrition.

Night blindness is a disease that is actually very common among the general population.

In ancient times, there were no electric lights and street lamps, and ordinary people could not afford to use oil lamps. So at night, it was really dark, and the people usually went to bed early, so naturally they didn't find out that they had night blindness.

And Ye Tianling, as the prince, plans how to defeat Ye Tianrui every day and night.

Vitamin A deficiency can cause night blindness.

Foods rich in vitamin A are mainly animal liver and animal meat, which are not affordable for ordinary families in this era.

Foods rich in vitamin A are mainly cantaloupe, broccoli, carrots, etc., which were introduced from other countries, and they are not suitable for large-scale cultivation in this era, so they are not easy to eat.

At night, he lost his sight and sought medical treatment, but no one could cure him.

The earliest record of night blindness appeared in the Yuan Dynasty, and the dynasty that appeared before the Great Qi State was the Sui Dynasty.

Ye Tianling opened the porcelain bottle, took out a pill from it, and looked at it carefully.

The pill was strangely shaped, and he had never seen it before.

The doctors gave him small pills, and it was the first time he had seen such a tablet-like medicine.

He couldn't help but ask.

"If this king takes this medicine, his eye disease will be cured?"

He cast a puzzled look at Wei Qingguan.

In the soft light, the woman nodded categorically, and there was no trace of falsehood in her beautiful face.

Ye Tianling held the pill in his palm, rubbed it gently, and asked casually: "If you can't cure this king, what should this king do with you?" ”

He said it lightly, but there was murder in his tone, which made her shudder.

After meeting twice, Wei Qingguan also had a certain understanding of Ye Tianling.

Ye Tianling only shows mercy to those who are good for him, and he has never been merciless to those who are worthless to himself, and he will definitely cut the grass and eradicate the roots.

For Wei Qingguan, it is very difficult to rescue Ye Shaomin.

Moreover, she also needs to show her worth in front of Ye Tianling, otherwise, Ye Tianling will definitely kill her.

Wei Qingguan looked at the cold eyes of the night sky, and the corners of his mouth hooked a brilliant arc.

"Your Royal Highness the Regent, at this moment, no one can save you except the courtiers."

Ye Tianling seemed to be poked in the sore spot, and looked at her coldly.

"It's not that this king doesn't believe you, but he is careful to sail the ship of ten thousand years!"

Wei Qingguan smiled but did not speak.

What Ye Tianling is most afraid of is to be known about his condition, as soon as the night comes, he can't see anything, if someone knows about it, he will definitely take advantage of the fire to rob.

Ye Tianling walked slowly in front of Wei Qingguan, leaned into her ear, and whispered a threat.

"This king has come to your aid, don't be ungrateful."

There was a thick murderous intent in her tone, as if Wei Qingguan dared to reveal a word to someone, and she would be slaughtered by him immediately.

This is a warning to her.

She, Wei Qingguan, was nothing more than an ant-like existence to him.

Wei Qingguan could only pretend to be obedient.

"The courtiers are willing to listen to the regent's dispatch, and the regent said that day, the nine princes of Qianguo want to marry the courtiers, and the courtiers think about it, since the nine princes are interested in marrying the courtiers, the courtiers can't make the regent embarrassed."

She spoke slowly, analyzing the pros and cons.

"As a citizen of Daqi, the courtiers should share their worries for the court and contribute to the Daqi country, if the courtiers marry into the Qianguo, the Kun country will also have some scruples, and dare not harass me again The border pass of Daqi, the courtiers marry a good husband, and they can also reduce the trouble of the border for Your Majesty and the regent, which is the blessing of the courtiers."

Ye Tianling looked at Wei Qingguan and felt that she was very pleasing to the eye today, and even her voice sounded a lot better.

The anger in his eyes dissipated a lot, and his complexion softened a lot.

"You can have such an awareness, this king is very pleased!"

Ye Tianling's face has always been unsmiling, but at this moment, it is smiling.

When Wei Qingguan saw that Ye Tianling's attitude had changed greatly, he knew that he had been tricked.

Ye Tianling didn't know that she had Fuhu in her hand, and she didn't know that Ye Tianrui was hidden by her.

Once Ye Tianrui wakes up and takes Fu Hu to the border to move the rescuers, at that time, Ye Tianling will fall from heaven to hell.

Killing the king and killing the father, this is enough to punish the nine clans.

Wei Qingguan pretended to be sincerely frightened, and continued to paralyze Ye Tianling.

"At that time, the courtiers didn't know the stakes, but the courtiers thought that they would leave their hometowns in the future, and they were uneasy.

"Well, it's best if you think like that!" Ye Tianling is in high spirits and in a good mood.

For a moment, Ye Tianling felt that he was a bold person, and in just a few words, he made Wei Qingguan obedient to him.

"Okay, this king is tired, and you have worked hard, go back!"

Wei Qingguan saluted and withdrew.

Ou Yu watched Wei Qingguan leave, and hurriedly ran to the imperial study, and saw his master's smiling and happy appearance at a glance.

"Your Highness, what's the big event?" Ou Yu asked puzzled.

"Wei Qingguan promised to marry the Nine Emperors of the Qianguo, he really helped the king!" Ye Tianling said with a smile.

Ou Yu knows Wei Qingguan too well, this woman is definitely not a fuel-efficient lamp.

The former Ye Tianrui was extremely wary of her.

Marrying into Qianguo, how could she easily agree!

Moreover, she also has a good impression of King Jing.

Ou Yu faintly felt that there was something greasy in this, and couldn't help but hesitate: "Your Highness, this woman Wei Qingguan is scheming, and she is by no means as pure as she seems on the surface, you can't trust her!" ”

Ye Tianling was proud, and suddenly someone poured a basin of cold water, and he was immediately unhappy, and he sneered at each other.

"What can a woman do, she has no background, no power, and marrying into Qianguo, she has only one way to die!"

He said it in no uncertain terms.

"Obviously, she wants to contribute to the king and pat the king's ass, but it can come out of your mouth, but it has become a conspiracy?"

"The subordinates are just worried about ......"
