He has never looked down upon his granddaughter because of her age.

His wife, Qing, has no flaws except her appearance.

His intelligence and character are more like the darling of God.

And from ancient times to the present, there has been no shortage of geniuses. They are so intelligent that they are almost demonic. They are born with knowledge and have a photographic memory...Many prodigies have left their mark on history.

Therefore, no matter how magical his granddaughter's performance was, Gu Heng would not doubt it, but would only feel happy and faintly regretful.

"Yeah! This is rock salt. It can be found anywhere near a river."

"Rock salt is poisonous!" Gu Heng traveled around the world in his early years and naturally had a lot of knowledge.

He had seen poor people who ate rock salt from the river and died of poisoning.

"You can use filtration to remove toxins from rock salt."

Gu Qingcheng said firmly.

Filtration, purification and other skills are the medical and chemical knowledge she learned during the Republic of China.

Because this has something to do with medicine, relevant knowledge points were also used when purifying penicillin.

Therefore, the system has not completely erased it.

Thinking of penicillin, Gu Qingcheng's thoughts moved again.

In fact, in ancient times, the ancestors of China also discovered penicillin.

I just didn't continue my research.

“Old mustard braised with mustard greens!”

In the previous mission world, Gu Qingcheng was the only person who lived until 2015.

She also read online articles and learned a lot of "time travel trivia".

Other memories were erased.

But Gu Qingcheng had an impression of the knowledge related to medicine in the Republic of China era.

For example, this "Old Mustard Braised".

It is the earliest penicillin in China and has been mentioned by many online writers.

As you can tell from the name, this is originally a kind of pickle.

It is said that in a certain temple, pickles were left for too long and a layer of mold developed.

By chance, the monk discovered that applying this moldy marinade to wounds could stop bleeding and reduce inflammation.

As a result, this temple has a "magic medicine" that will be given to the sick people around it.

If there is a connection with the temple, even if the disease is cured, people will associate the credit with the gods and Buddhas.

Then there was no in-depth study of mustard stew, and the opportunity to develop penicillin was missed.

...Uh, okay, these are Gu Qingcheng's own guesses and fabrications when he saw those online articles.

What is the truth of history, and how will future generations know it?

However, this story inspired Gu Qingcheng.

"Maybe I can try to refine it, maybe I can make penicillin?"

The mustard stew is a real item in history. Gu Qingcheng made it, so it shouldn't change history.

At most, at most it was purified several hundred years in advance!

Gu Qingcheng originally didn't want to get the anti-inflammatory medicine out so early.

But this time they were exiled to Lingnan.

There are many miasmas in Lingnan, as well as snakes, insects, rats, and ants. If you don't handle them properly, you will be injured, sick, or even poisoned.

Anti-inflammatory drugs are not a panacea, but they can also cure some diseases.

The more preparations, the more Gu Qingcheng can feel at ease.

The large army continued to set off, and when Gu Qingcheng was on the way, he would search for old pickles along the way.

Zheng Mo:...This little girl from the Gu family is really capable of doing things.

Even the pickle jars of poor people are not spared.

The days on the road are monotonous and boring.

Even though Gu Qingcheng found a lot of things for himself, he was still a little bored.

"Executor, since it's boring, let's do a task."

Huoshui jumped out in time to increase his presence.

"That's fine!"

Gu Qingcheng looked at his little black hands, and then touched his dry and yellow hair.

Alas, it's so ugly, it really needs to improve its appearance.

"Then let's do a mission."

Gu Qingcheng lay in the bullock cart, turned away from Lu Qi and other slaves, closed the window, and was ready to "time travel".

"Okay! Executor, don't worry, I will randomly select an easy task for you."

In his excitement, he started talking nonsense.

Gu Qingcheng's forehead twitched: They said it was randomly selected, how can you choose a good task?

Not long after, a new summary of the novel was delivered to Gu Qingcheng.

Gu Qingcheng clicked on it, and then fell into a state of contemplation——

Ah this?

Are you sure the system is not intentional?!
