Lin Minghao's eyes flashed with fierceness, and the answer became obvious.

The person who is poisoned is very patient, and the method of piercing with water drops and stones allows the poison to accumulate in his body little by little.

Only by accumulating day by day will I become accustomed to it and not pay attention to the changes in my body.

Since this is a long process, the person who poisoned it did it a long time ago.

Recalling carefully, he found that what the executor Lin Zou said was right.

He is usually cautious, he will not try anything strange, and he will not rashly let strange cultivators enter the City Lord's Palace.

After fighting the flame monster snake in the ruins, he was hit hard and his realm fell, and he has been hiding in the palace for several years to recover.

Another thing Lin Zou must have said is right, he has been taking tonic decoctions and pills in the past few years to assist in recovering the realm.

The only way to poison is to start from these things and let yourself eat the poison.

Thinking of this, Lin Minghao left the study and walked quickly to the back of the palace.

There is a huge kitchen hall there, and the tea I drink, the pastries and fruits I eat on weekdays, and the decoction pills I take are all from the kitchen hall.

The kitchen hall is a simple square house, made of stone bricks and bricks.

Inside is a spacious and flat space, which can park more than 30 carriages, like a solid and solid warehouse.

In the spacious space, alchemy stoves, stoves, medicine jars and other objects are neatly placed, and they are cleaned spotlessly.

At this time, the kitchen hall was empty, the alchemists and cooks were not there, and they didn't know that the city lord had returned.

Lin Minghao opened the medicine jar for boiling the decoction and checked them one by one, and also shoveled out the medicine residue in the alchemy furnace and rubbed it to distinguish it.

I have taken all of these types myself, and the smell is extremely familiar.

He packed the residues in a bag, then left the kitchen hall and went to the warehouse where the medicinal herbs were stored.

In the City Lord's Palace, there were four warehouses for storing medicinal materials, and the highest one stored the medicinal materials that Lin Minghao was taking.

He took the exemplar outside the warehouse away, and then went in to examine the herbs.

Some of the types he knew, while others were very unfamiliar, so he took out the empty bag and took away the herbs he didn't know.

In the Great Wilderness Lonely City, there was originally only the Great Wilderness Pill Supermarket that sold medicinal materials, and others wanted to do a medicinal material business, but they couldn't compete with Boss Zheng.

However, just half a month ago, Boss Ning of Dahuang Supermarket suddenly announced that he would merge the pill supermarket next door into his own name and let his daughter Ning Mufeng run it.

At the same time, after Boss Zheng of the pill supermarket followed the city lord out of the wilderness, he never came back, and the supermarket's supervisor of Kanchi was nowhere to be found.

With the departure of Boss Zheng, the medicinal materials sold in the pill supermarket gradually exceeded the demand, and the number that could be put on the shelves every day became less and less.

Only then did Ning Mufeng and Boss Ning know that without Zheng Qiu, there would be no large number of fresh medicinal materials, and once the inventory of the pill supermarket was sold out, the supermarket would have to close if it was not closed.

The father and daughter were reluctant to let the supermarket plant in their hands, and hurriedly sent someone to temporarily plant medicinal herbs.

But in an arid place like the Great Wilderness, where the yellow sand is full of sky, without Zheng Qiu's special energy, how could it be possible to grow enough fresh medicinal materials.

And other business owners, seeing that the pill supermarket is not as good as day by day, they seized this opportunity to also start a medicinal herb business.

They each found a way to show their magical powers, and got medicinal materials from outside the great wilderness to sell through the post station.

There are more shops doing medicinal herb business, and there are more cultivators who understand medicinal herbs in the Great Wilderness Lonely City.

Lin Minghao carried the bag and went door-to-door for these shops to identify and analyze the types and effects of Chinese medicinal materials in the bags.

After walking around the city, combined with the identification results of more than a dozen medicinal herb shops, he got the answer he wanted.

In the medicinal residue of the Alchemy Furnace of the Kitchen Palace, there is a certain toxin that will hinder the power of the meridians.

And in the medicinal materials in the warehouse, there is nothing that carries this toxin.

In other words, there was no problem with the medicinal herbs sent to the City Lord's Palace, and that bastard traitor added poison to it when he was alchemy.

This answer also confirmed what Zheng Qiu said, Zheng Qiu was not the one who poisoned him, and all the medicinal materials he sent were tonics.

Lin Minghao threw away the bag, rushed back to the palace with a black face, and ordered the executor to summon all the alchemists of the kitchen hall to the side hall in the name of refining the new pill.

The executor did not know the truth, and notified all the alchemists according to the order.

Knowing that the city lord had returned and was going to refine the new pill, the alchemists hurried to the palace from their respective residences.

Entering the hall of the side hall, the alchemists lined up in a row, waiting for the arrival of the city lord.

Soon, Lin Minghao strode in from the door and asked without looking, "Are all the alchemists here?"

The exemplars in the hall replied, "All of them!"

Lin Minghao took the executor away, waved his hand and fanned out two waves of qi, slamming the door shut.

At the same time, the air blew through the walls, and the windows snapped shut.

The continuous sound of doors and windows closing frightened the alchemists, and when they saw the city lord's ugly face, they were even more afraid.

Lin Minghao sat down in his seat and snapped on the armrest.

He asked coldly, "Who refined the pills I have taken in the past few years?"

The alchemists' hearts were shocked, and they didn't know why the city lord lost his temper, but looking at this look, maybe someone would splash blood on the spot today.

"Stand on your own...... Go out...... Come on!"

The city lord's tone became more and more cold, like a sharp knife, scraping a rustle on the whetstone, ready to be stained with blood at any time.

There were six alchemists who didn't dare to continue to hesitate, and stood up trembling with their heads trembling, their legs trembling.
