Seeing that Hong Xiaoduo nodded, Old Man Luo felt a surge of guilt again.

Ever since I brought this girl to this era, I've only learned from the occasional questions she asks after each phone call that she hasn't had a peaceful time here.

In the past, when we connected online, she would be emotional, and even if I tried to talk to her calmly, she would always snap at me. Now, our relationship has improved somewhat.

However, neither before nor now has she told him about her specific experiences here, so he hasn't deliberately inquired about them. He has simply done his best to meet her needs.

A few days ago, she left a message on her social media, saying she needed something that could test whether water sources and food were safe. She also said that it would be even better if it could display what kind of reactions people would have after consuming the detected substances, and what kind of consequences it would cause.

Seeing the urgency in her message, Old Luo quickly called his students to stay up all night to solve the problem, and even divided the items into two parts according to her request.

One of them looks like an ordinary bracelet made of soapberry seeds, but it's actually a replica made by Old Luo using a special material to test the safety of food and water. If there's anything unusual, the beads will change color; the more toxic the substance, the darker the color.

You don't even need to deliberately touch it with the beads; close proximity is sufficient.

Hong Xiaoduo took Yuheng's words to heart. She thought that if it was really Hei Wuchang secretly watching and waiting for an opportunity to act, what if such a mentally unstable person would try to use some underhanded tricks?

After all, if he had followed them for a long time, he must have witnessed them dealing with mountain bandits and sea pirates. If he had any sense and didn't have a powerful helper, he would never have taken action openly.

That being said, if he had capable assistants who were confident in handling the situation, he wouldn't have stayed hidden in the shadows.

Hong Xiaoduo pondered that if the other party was using underhanded tactics, they would most likely tamper with the food.

After all, they were always on the road, and most of their meals were eaten on the road. However, they bought their ingredients from towns and villages, and the people they bought from were not sure what they wanted to buy. It was very difficult to tamper with the ingredients in advance.

However, the safest approach is to figure out their travel and rest patterns, estimate their journey, and then tamper with the water sources at suitable resting spots along the roadside.

So, Hong Xiaoduo went into the space and left a message for Old Man Luo asking for something.

I just didn't expect that Old Luo is becoming more and more reliable, and he actually got it done very quickly.

Furthermore, he considered everything very carefully, designing the test items to resemble a soapberry bead bracelet. Soapberries grow in many places by the roadside, and in ancient times, they were believed to have powerful purifying properties, bringing good luck and warding off disasters.

Tianxuan took care of all the food along the way, and having him wear this bracelet wouldn't attract attention from others.

The other part of the testing is still inside the space. Tianxuan needs to take small samples of the abnormal ingredients or water and give them to Hong Xiaoduo. She will enter the space and use the testing device to analyze what the ingredients are, what the reaction will be if someone is infected, and what the consequences will be.

Of course, in addition to explaining the function of the Tianxuan bracelet, she also told other people about possible situations and how to react after receiving specific signals from her and Tianxuan.

When she told everyone about it, none of the nine people, from top to bottom, thought she was making a mountain out of a molehill or that she was overthinking things.

Everyone listened attentively and kept her instructions in mind.

As it turned out, the facts proved once again how accurate her prediction was. Heaven knows how excited Tianxuan was when she saw the bracelet on her wrist change color while she was fetching water from the spring.

This evening, everyone received a specific signal and reacted as if they were poisoned. The sweat on their brows made their reactions even more realistic, and Black Impermanence didn't suspect a thing.

In this season, the temperature isn't even high at midday, let alone in the evening; you wouldn't sweat unless you had extreme abdominal pain.

However, what Black Impermanence didn't know was that the sweat on these people's foreheads wasn't due to poisoning or stomach pain. It was purely because it was their first time doing something like this, and they were afraid that if they didn't act convincingly, he would see through their act and affect Hong Xiaoduo's important business. They were so nervous that they were sweating!

Thinking of the scene when everyone acted together this evening, Hong Xiaoduo's lips involuntarily curled up again. This is tacit understanding.

"Oh right, didn't you always complain that this space is useless and you can't store things in it?" Old Luo remembered and said.

Upon hearing this, Hong Xiaoduo's eyes lit up: "What, you've fixed and improved this defect, so now I can procure supplies and bring them in?"

Old Luo shook his head, watching the surprise on the other person's face visibly turn into disappointment, and quickly continued, "As you know, this space was created by my grandfather. I don't know what he was thinking back then. I guess it's because the times are different, so the ideas are different too."

Although I haven't been able to fully crack the original key yet, and therefore can't solve this major flaw that prevents you from storing resources, I suddenly had an epiphany these past two days: why should I worry about how to fix and improve this?

"I can easily create another space for you to use. Then you can put whatever you want in it."

"That would be great, but can you actually do it?" Hong Xiaoduo didn't mean to question, but she didn't really like to accept empty promises from others.

She wasn't stupid; how could she not see that Old Man Luo had been trying to please her all along? How could she not sense his guilt?

Old Luo didn't care at all whether Hong Xiaoduo was questioning his abilities, and said very seriously: "I can definitely do it. I'm already starting to prepare. They say the Yangtze River's back waves push the front waves forward. There's no reason why I can't even catch up with my own grandfather."

"Don't worry, Xiaoduo. I'm not just bragging about drinking baijiu after a few beers. I always do what I say."

Looking at the increasingly pleasing old man in front of her, with the Mediterranean Sea above his head, which seemed to stretch even wider, Hong Xiaoduo couldn't bring herself to remind him, "No matter how powerful you are, you still haven't been able to crack the key set by the old man."

Then, thinking about how she would occasionally make small requests of him, she gave up on her plan to persuade him to focus his energy on cracking the original system key.

The crayfish were very flavorful, with a springy texture. After a few bites, a sip of wine made me feel slightly tipsy, which was incredibly refreshing. In addition, in the evening, I confirmed with Bai Wuchang that the villain who abused the children was indeed dead, which put Hong Xiaoduo at ease.

Meanwhile, Old Man Luo was also in a very good mood.

He has sons and grandsons, but they are all busy with their own things, and they only come home to reunite during a few important festivals throughout the year, such as the Spring Festival, Mid-Autumn Festival, and Dragon Boat Festival.

They would occasionally call or video chat, but Old Luo always felt that something was missing.

"Xiaoduo, if you meet someone you like here, and they like you too, then don't have any reservations, just love them..."
