The 400 million points were quickly squandered by Yang Ning, which upgraded Yang Ning's safe house to several levels. Not only did it have a large number of electromagnetic railguns, but it was also arranged under Su Yucheng's ass two hundred miles away.
In addition to a batch of electromagnetic railguns, Yang Ning also built a batch of close-in defense guns near these electromagnetic railguns to deal with Qi practitioners who want to get close to the electromagnetic railguns and protect the safety of the electromagnetic railguns.
Around Yang Ning's house, he landed a batch of anti-air missiles with a maximum range of three hundred kilometers. It was a simple matter to fly five hundred kilometers.
Not only that, these missiles also have a heat-seeking effect. If they stare at the Qi practitioner, they will explode close to the Qi practitioner, which is extremely cruel.
In addition to these, there are also satellites with a detection distance of five hundred miles. In the minds of Su Yucheng and Zhao Han, Yang Ning's personal domain is still two hundred miles. However, Yang Ning's domain has unknowingly expanded to five hundred miles.
If they come with malicious intentions, the consequences can be imagined.
"Ding dong, congratulations to the host for upgrading the system. After deducting 30 million points, the biotechnology mall is opened."
Yang Ning upgraded the safe house to a satisfactory level, and with the last remaining points he finally opened the biotechnology mall that he had longed for. The opening of this mall meant that Yang Ning could finally get close to the system's biotechnology, and it also gave him
The possibility of immortality.
He couldn't wait to open the interface of the biotechnology mall, and what he saw was a variety of potions covering the screen, including strengthening potions, agility potions, strength potions, etc. There were so many of them, Yang Ning swiped down the interface and kept thinking silently.
: "It must be there, it must be there."
Whether his system can beat the Qi Practitioner's training system depends on whether the system can produce immortality potions. If not, then the system can only become a vassal of the training system, assisting Yang Ning to become a Qi Practitioner. And if he has
, then Yang Ning can completely abandon the path of becoming a Qi practitioner, and then embark on a completely different path in this world where cultivation is the most important thing.
Yang Ning kept swiping down, and his heart became heavier and heavier. Suddenly, Yang Ning's eyes froze and he stared at the bottom of the biotechnology mall. There was a gray grid there, and under the grid was
Four big characters, although dim, were radiant in Yang Ning's eyes: "Elixir of Immortality!"
Yang Ning clicked on the box for the longevity potion in surprise and carefully read the introduction about the longevity potion.
"The elixir of longevity can be used to increase the number of cell divisions, up to 300 times. It cannot be reused. It is produced in the first-level biotechnology mall. The upgrade mall displays the second-level elixir of longevity."
Yang Ning was overjoyed. As a college student who traveled through time, Yang Ning was very clear about this introduction. On the other side of the earth, the life span of living things is closely related to the division of cells. The more times a cell can divide, the more times it can divide.
, then the life span of the organism will be longer.
As for why there is a limit to the number of cell divisions, this is because there is a structure called telomeres at the ends of chromosomes. Telomeres are composed of highly repetitive base sequences. Every time a cell divides, telomeres will lose part of the sequence.
Telomeres shorten, and when telomeres shorten to a certain length, cells can no longer divide.
The longevity potion in this biological mall obviously starts from this point, using the potion's effect to supplement the loss of telomere sequence during cell division.
The number of cell divisions in an ordinary person's lifetime is about fifty, and the lifespan of each generation of cells in the human body is about two and a half years. Fifty times means that an ordinary person can have a maximum lifespan of one hundred and twenty years. Now
This longevity potion can cause cells to divide up to 300 times, which means that as long as the potion is used, the lifespan will be at least 720 years.
"It's a pity that it cannot be reused."
Yang Ning regretted this, but think about it, the immortality that can be bought by just earning points is much better than the immortality state that may not be achieved after a lifetime of hard training. Although the medicine here
It is impossible to reach the level of longevity that is comparable to that of the Immortality Realm, but this mall can also be upgraded. After the upgrade, there will be a second-level longevity potion. Presumably the longevity potion provided by the longevity potion at that time will not be inferior to that of the Immortality Realm.
Already.
"Let's see how much it costs."
Yang Ning rubbed her hands and looked at the redemption points for the longevity potion. Upon seeing this, the young man's face instantly became extremely exciting.
The little fox was digesting the benefits of the spirit stone in his sleep. He vaguely heard a scream that could pierce his eardrums; "Fifty technology points, why don't you grab the system? That's five billion points, isn't it?"
We agreed that the first-level malls are all based on points, and only the second-level malls use science and technology points as the price unit? You only sell things here with science and technology points, how can I afford it? Even the atomic bomb only costs one billion points!"
Yang Ning cursed for a long time. No wonder he was so rude. One technology point is equal to 100 million points, and 100 million points is equal to two thousand spiritual stones. Fifty technology points. This is a hundred thousand spiritual stones. It is Qingyun Sect.
Immortal sects like Ziyun Sect spent ten years mining all the spiritual stone reserves in the spiritual veins.
It will take God knows how long it will take for him to earn so many spiritual stones!
"Hold on, hold on, it's just fifty technology points and one hundred thousand spiritual stones. Every inch of time is worth an inch of gold. An inch of gold can't buy an inch of time. You can buy a life span of 720 years with a hundred thousand spiritual stones. This is already
Very good, it’s almost one hundred and forty spiritual stones a year, one hundred and forty spiritual stones,
1.4 million taels of silver. The current price of silver is about 3 yuan per gram. One tael of silver is 50 grams, which is 150 yuan. 210 million yuan. With such a small amount of money, you can buy a
Years of life is nothing in front of the giants on earth, I can earn it."
Yang Ning comforted himself. Compared to the people on Earth who couldn't buy lifespan even with money, he had such a channel that surpassed those who knew how to do it. Although it required a very large amount of funds, as long as he wanted to
If you think you can live for seven hundred and twenty years if you have enough money, that's still very motivating.
At this time, Yang Ning turned his attention from the longevity potion to other potions. Almost all the products in this biotechnology mall are potions, which can strengthen the effect, increase agility, increase strength, and increase all aspects of the human body.
, some are very useful, and some are very useless, such as medicines that can grow hair, which can promote the development of hair follicles and promote the growth of hair.
"Put this thing on the other side of the earth and package it into a hair growth agent. The effect will be great, but it's a pity that I don't need it."
