The physical quality of this body is too poor, even if Gu Ruyun has taken the genetic evolution potion and body quenching potion during this period of time, and has practiced the interstellar body refining technique, but the time of these things is still too short to make this body work. At the level of invulnerability, there is no way to use mental power to change the trajectory of bullets and swords.

Gu Ruyun thought for a while and decided to prepare a batch of potions before going to Anhai City.

As a doctor, there is nothing more reassuring to her than potions and medicine.

As the chief military doctor of the empire, Gu Ruyun will configure not only medicines to cure diseases and save lives, but also medicines that can be used on enemies on the battlefield, such as highly toxic medicines, paralysis medicines and other negative medicines.

"With these medicines by my side, even if Xu Rantong's plan is as he said that day,

When he thought of it, he did it, and Gu Ruyun began to make potions.

The preparation of potions is a very tedious thing. After returning home from school in the afternoon, Gu Ruyun has been staying in the pharmacy in the back garden.

"Uh, this highly poisonous medicine needs to use red sunflower, stamen, and pine sound... These medicines are crops from other star fields, not the original varieties of ancient earth. In this case, they can only use other The existing medicinal materials have been prepared."

"Chiyanghua, the medicinal property is domineering, if you touch it with the back of your hand, you will feel a strong burning sensation on the skin... Once this medicine is taken into the stomach, the whole person's stomach will be in unbearable pain, as if being It's like a man grabbing his throat and stuffing hot charcoal into his stomach..."

"Well, since Chiyanghua doesn't exist, then I'll use Ten Thousand Years Grass and Blood Scorpion instead..."

"Uh, the medicinal effects of these two medicines don't seem right..."

"Then try the red vine, the incense of earth wood, and the deployment of Qianli grass to see if it can replace the red sunflower..."

"Why did it fail again... I have to try again."

Gu Ruyun stayed in the pharmacy and kept blending, constantly recombining the medicinal materials with the existing medicinal materials in his hands, and took notes to record the proportion of each medicinal preparation, the result of failure, and the reason for the result, etc. a situation.

With Gu Ruyun's painstaking configuration, after successfully refining the highly toxic potion, she even had the luck to prepare a bottle of real potion.

As the name suggests, the real potion is a potion that can tell the truth. This potion was specially rationed to prisoners of war in the army in the past.

The lavender potion exudes an abnormal color, and it is particularly creepy to look at.

Gu Ruyun glanced at this precious bottle of real potion, and a thought suddenly appeared in his heart, "It would be great if Xu Rantong could drink this real potion in public."

When this kind of thought arises, it is like a weed that has taken root, no matter how you burn it, it will not be burnt out.

Gu Ruyun has a plan in his heart, and the action of preparing the potion in his hand becomes faster and faster.

The highly toxic potion, the paralyzing potion, and the real potion took Gu Ruyun two full days. By the time Gu Ruyun came out of the pharmacy, it was already the next afternoon.

With these potions in his arms, Gu Ruyun walked across the path in the back garden of Xiao's house and walked towards the villa.

However, only halfway through the road, Gu Ruyun heard a series of sharp cat meows and a series of low-pitched dog meows.

Gu Ruyun frowned, "Why did this little white quarrel with Heihu again?"
