This remark gave researchers a lot of inspiration.
"However, mercury is poisonous. Do you know this?"
Researchers are as excited as Columbus discovering the New World, sharing their findings.
Dongfang Xiaoyu really doesn’t know this.
After all, in this era, mercury is called "liquid beads", "magic glue" and "spiritual liquid".
Everyone's thoughts and inherent concepts are that this thing is a rare thing that only appears when masters and immortal masters refine elixirs, especially elixirs of immortality.
How could it be poisonous? It should be nutritious, prolong life, and beautify your appearance!
But Pei Mengqing knew that, he also knew that ancient cosmetics contained mercury, so after using too much cosmetics, a woman would become even scarier after removing her makeup and turn into a yellow-faced woman, maybe like a ghost.
On the other hand, ordinary women who cannot afford rouge powder at home, even if they are old, and even if their facial skin is weathered, is much better than the yellow-faced woman with mercury poisoning.
"I know, it's highly poisonous, and its density is more than ten times greater than water."
Pei Mengqing couldn't remember how many times it was, maybe thirteen times?
"Density?" The researcher thought for a moment and probably understood.
But Pei Mengqing still needs to explain it, lest these guys misunderstand it again.
"It is the weight geometry of the same volume. For example, a wooden box of cotton and a wooden box of iron have different weights. Divide the weight by the volume, which is the density. The heavier the weight of the same volume, the greater the density. Boat, you know Well, it can float on the water because its overall density is less than that of water."
In view of the use of water as a thermometer, Pei Mengqing really doesn't trust these so-called researchers now.
It would be even more terrible if another explosion accidentally occurred. Tianhe County, which has been plagued by disasters, could not withstand such a torment.
"Oh, I understand. It's just that we haven't been able to find the right words. Your density is very good. Can we use it in our graduation thesis?" The researcher nodded, looking like he was asking for advice humbly.
"Please." Pei Mengqing thought for a moment and said simply, "Please go to a drug store or some other place to buy some mercury and come back. Let's make a thermometer together."
It is better to control the general direction by yourself, manufacture reliable thermometers as soon as possible, and then try to mass-produce them.
At present, this is the only stupid method. Otherwise, based on their body surface perception, it would be really difficult to find where is colder and where is warmer.
At least, the system mission should not be the kind of rubbish mission that "there is an ice spirit bead somewhere, so it is very cold, because the ice spirit bead affects the whole city."
Later, Pei Mengqing spent the entire afternoon studying the thermometer with these guys and measuring the standards as much as possible.
Standards are the most difficult thing. Weight, length, temperature, air humidity, etc. all need a unified standard before they can be widely used so that everyone can understand what a certain unit under a certain number actually represents. What are you wearing?
If not for Pei Mengqing's previous life, why would historians affirm Qin Shihuang's great measures of weights and measures?
Until evening, Pei Mengqing left Qingyu, who was more curious, to supervise the work in the laboratory, while she returned to her dormitory and started practicing again.
"Exchange for a soul nourishing pill." Pei Mengqing said silently in her heart.
[Redeem successful, Soul Nourishing Pill has been distributed]
[20 points will be returned after 100 points are spent, and 80 points will be divided by eight discounts, leaving 858 points remaining. The accumulated consumption is 2703 points, and there are 22 points left before the next rebate. 】
"Speaking of which, when will the 20% off and full discounts be extended now?"
Pei Mengqing remembered that after completing the mission in Liangzhou County, she was successfully promoted to the soul-nurturing realm.
The system mall simply made a major upgrade, and then announced that the major promotion event would be extended for two months.
[If the host successfully completes the phased continuous tasks, the big promotion will last until early May this year. 】
"Then if I break through the soul-nourishing realm before the beginning of May, will the promotion be extended?" Pei Mengqing asked expectantly.
[It depends on the situation. Please continue to work hard, the current situation is not optimistic]
[Please understand one thing, the host. The existence of this system is not to prevent the host from becoming stronger, nor is it to punish the host through difficult-to-complete tasks]
[Rather, I hope to quickly but steadily help the host improve its strength to cope with the continuous crises in the future. 】
It is difficult to say so many things that have nothing to do with the system settings in the practice system. Pei Mengqing carefully recalled how the system had helped her during this period, and felt that this was indeed the case.
However, the constant stream of crises sounds very troublesome...
"Well, there is no trouble and hardship, and there is no way to quickly improve my strength. If I can't become a Sword Immortal earlier, I won't find a way to go home. I just work hard."
[The host’s awareness is very good, please keep up the good work. 】
After praising him, the system disappeared and no longer disturbed Pei Mengqing's practice.
Pei Mengqing swallowed the soul-nourishing pill, raised her heart and began to run the "Secret of Immortality".
The spiritual energy immediately began to flow rapidly through the meridians in his body, like a comfortable warm current, warming his body and mind.
If at the beginning of his cultivation, his veins were like country roads, then now his veins are like the avenue to the sky that can pass ten carriages at the same time.
Like a highway, spiritual energy flows rapidly through the body, and at the same time, a vortex-like suction force is generated.
Moisturized by the soul-nourishing pill, the "network points" between the soul and the body began to connect quickly, and the progress continued to accelerate.
The closer the fusion is, the faster the speed will be. Maybe after the thermometer is successfully manufactured, Pei Mengqing will be able to achieve the perfection of the soul nourishing device!
With this idea in mind, Pei Mengqian felt that his soul and body quickly merged together, and the feeling of unfamiliarity gradually disappeared.
However, just when he was feeling comfortable practicing, a familiar pull came.
He didn't resist, but followed the pull and appeared in the underground seal again.
"Long time no see. It seemed like you were not in this city before. I didn't sense you." Canglan said.
"We went on a mission last week. We went to other counties in Liang County and found that all other counties and villages were captured by the zombie virus. Only a few survivors were still alive. There were tens of thousands of remaining zombies, all of which were coming in a steady stream. Go outside Tianhe County and besiege the city."
Pei Mengqing briefly explained the reason for her absence.
For some reason, when Canglan asked about the reason for his absence, he actually felt nervous as if he was being checked by his girlfriend.
I don't know if it's because Canglan is so beautiful, and everyone loves beauty, so Pei Mengqing can't help but have a crush on her.
"I see, the temperature on the ground is very low now, right?"
After a week of experience, Canglan seems to be in good condition.
At least it's not like the previous two times, where we fell asleep after just saying a few words...
