In a blink of an eye, it was August 21, and it had been five days since Zhai Xiying left the capital.

After Youruo accepted Qu Liyan's persuasion, he obediently stayed in King Ying's mansion and studied the hundred pests sent by the Hades Palace.

At first sight, if you come into contact with the pest, you will recognize it as a planthopper, which is a pest that specifically harms the planting area, such as corn, rice, sorghum, wheat and other grains, and reproduces very quickly!

It is no wonder that the crops in the northwest and southwest have been severely destroyed, and almost no grain has been harvested, which is caused by these planthoppers.

Among the pests sent by the Hades Palace, in addition to planthoppers, there are also a small number of locusts. Locusts have always been the natural enemies of plants... But this time, the insect plague is mainly dominated by planthoppers.

Qu Liyan stayed alone in the pharmacy with Youruo for the past few days, because they were all flying insects, and the door of the pharmacy could not be opened, so as not to lead the pests to the soil of the national capital.

I can only stay outside the pharmacy, listening to the movements inside, sometimes as loud as thunder, sometimes small and not the slightest sound can be heard. He stood a foot outside the pharmacy, listening to the sound coming from the pharmacy, and his heartbeat was synchronized with the movement in the pharmacy.

After four days of hard research, Youruo wants to call himself an expert in pest control. At the same time of making the medicine, it is necessary to kill planthoppers and locusts under the condition that it is harmless to crops.

Thanks to the insecticides that have been developed in the 21st century, some herbs with similar effects have been replaced by ready-made herbs.

After four days of research, combined with the information in my memory, the 'Wonderful Hand' insecticide was born.

The seven days agreed with more than a dozen senior monks of Lingxuan Temple are coming, and the amount of medicine is not enough, and it is understood that the affected area has hundreds of acres! Hundreds of acres of land, that's vast from the edge!

There is no time to make a large number of potions in King Ying's Mansion, and if you inform Fan Bo of the materials and dosage of the potion, you can only hand it over to Fan Bo to the Western District and let him help!

On the twenty-first day, Youruo no longer stayed in the pharmacy, she was busy for several days, and even at night she was studying deeply, her bulky and tired body, after being relaxed, was already tired and paralyzed.

But Qu Liyan still came to the door as usual, and the time they got along with their belly in the past few days, they were like returning to the days when they practiced martial arts together.

Sitting on the eaves of the house together to study martial arts routines, practicing in the open space together, eating roast chicken and drinking wine together in the grass hut... Although the things he has done in the past few days are different from before, he is still working with him, and the feeling is still the same.

"Is my belly in the house?" Qu Liyan came to Ying Wang's Mansion, and he really didn't go through the gate a few times.

Outside King Ying's mansion, it is useless to have a formation as a line of defense! Don't forget that it was made up by Master Wuyi, Master Qu Liyan, and the method of unlocking the formation, Qu Liyan had already discussed it with Master Wuyi.

The current Qu Liyan is as diligent as coming to the Ying Palace, but this is only in view of... When Zhai Xiying was away.

"Miss Lu is indeed resting in the house, Little Prince Qu, is there something wrong?" Day by day, more and more precautions against Qu Liyan, these days Qu Xiaowang and Miss Lu are in the same room alone, and they are guarding outside like witnesses waiting to be caught!

Ri's first reaction now is that the Xicheng insect plague has been solved, and he can't let Qu Xiaowang and Miss Lu be alone anymore! If the master knows, the life of the day will be lost!

"Inside, huh? Then you can get out of the way. Qu Liyan stepped forward and put his hand on Ri's shoulder.

From the eyes of ordinary people, they thought that Qu Liyan was just nudging the day, and the day retreated to the side. In fact, the two men are secretly competing with their internal forces, but Ri is not Qu Liyan's opponent.
