It was a box made of special metal, and after opening, square cards were neatly placed in it, and the top card was a military general riding a tall horse and holding a red order flag, and the edge was clearly written with "Jade Qilin Lu Junyi".

"It turned out to be the Water Margin Card?" Lin Su immediately became interested. I took out all the cards in the box and looked at them one by one, and was surprised to find that there were one hundred and seven consecutive Water Margin cards in the box. Except for Song Jiang, who ranked first, the others have already been collected.

I didn't expect that Brad guy to have such a hobby. But it's normal to think about it, when Brad came to the human world, it happened to be the rise of the food writer Shi Nai'an, and the two can be said to be people of the same era.

And the two have another thing in common, whether it is Brad or Shi Nai'an, both of them are extremely good regeneration masters.

Shi Nai'an has created such a magical thing as crispy dough fruit, and it is impossible for Brad not to pay attention to it.

At the bottom of the box, Lin Su also found a yellowed booklet, and when he opened it, he found that it was actually the research record left by Brad when he was researching the Water Margin card.

"During this time, a book called "Water Margin" went viral in the human world, and I asked people to buy a copy out of curiosity. Carefully studied, the story is fascinating, and it is indeed a rare masterpiece. Each of the one hundred and eight heroes is portrayed vividly, which is really rare.

Later, I heard that Mr. Shi Nai'an took one hundred and eight generals as the core and created a plant called crispy dough fruit, and each fruit would produce a card. Curious, let people retrieve a crispy dough fruit and study it carefully.

……

It's amazing how the cards produced in these fruits can automatically generate specific words and pictures?

……

After more than half a year of researching the crisp dough fruit, I finally discovered the secret of its internal cards. The genetic material responsible for the card generation part of these fruits is composed of multiple sets of unstable genes, and different environments affect different genes, and 128 different situations can be combined by using their dominant recessiveness, each of which represents the content of a card.

Simply dough nuts will produce different cards in different environments, and most people must travel all over the world if they want to collect all the cards. There shouldn't be anyone in their lifetime who collects all the cards and uncovers the secrets behind them.

……

By simulating the low-temperature and low-pressure environment of Ice Hell, all the crispy noodles were successfully made to produce the card of Iruyun Dragon Gongsun Sheng, and it has been confirmed that the type of card produced can be controlled by artificially changing the environment.

After many comparative experiments, it can be determined that there are six main environmental factors controlling the dough fruit: temperature, air pressure, oxygen content, gravity, light, and carbon dioxide content.

It occurred to me that since the genes of the doughnuts could be changed through environmental factors, why not just try to genetically modify the dough nuts?

……

Genetic modification failed, genetic changes caused by unnatural environments could not bear cards, and this plant apparently had secrets that I didn't know.

……

Genetic modification has been completely abandoned, and plans have been made to use altered environmental factors to influence the content of the cards. ”

This record is followed by a series of tables detailing the environment in which each card was cultivated, and the time when each card was cultivated.

Turning the page to the last page, Lin Su calculated that Brad's cultivation of crispy noodles had been more than thirty years. Obviously, even if we know the main factors that affect gene expression, it is not a simple matter to use exhaustive methods to breed.

And there are some factors that Brad doesn't know about, which also greatly reduces the progress of the experiment.

For example, the card of Black Whirlwind Li Kui, I don't know if it was because of the poisonous wine in the original book, but Brad finally used the water of the poisonous tide that surrounded the human world to irrigate the crispy noodles and fruits, and only then did he get such a card.

There is also the card of the dangerous Dao God Yu Baosi, no matter what method Brad uses, he can't cultivate it. Later, another subordinate who took care of the plantation accidentally damaged a leaf of the crispy dough fruit, and as a result, he got the card by mistake.

According to Brad, 94 of the 107 cards can be reproduced in the recorded environment, and the remaining 13 cards cannot be repeated.

After reading Brad's experimental records, Lin Su couldn't help but secretly say that he was lucky. If you go and collect these cards one by one, I don't know how much time it will take.

"No, since Brad spent thirty years cultivating 107 cards, he should have cultivated all of them in a thousand years. Why was there one missing in the box? Didn't he put it in the box?

Or is it that Brad has collected all the cards, unlocked the hidden secrets of the cards, and destroyed one of them?"

Thinking of this, Lin Su hurriedly rummaged through the experiment manual, hoping to find more clues. On the penultimate page of the manual, Lin Su saw a record of Brad's decision to terminate the experiment.

"It's been 30 years since I got my 107th card, and I still can't take the last step. Shi Nai'an is a genius regenerator who has managed to trick everyone. ”

Although it is only a short line of words, the resentment and unwillingness revealed in it have not diminished even after thousands of years.

Brad has always prided himself on being a genius regenerator, and although fusing the Eight Kings bloodline caused him to have physical problems, Brad blamed this failure on his own greed rather than technical problems. If only the body of Herac's cub had been fused, nothing would have happened after that.

The inability of such a genius regenerator to solve the puzzle left by another regenerator is nothing more devastating to a proud man.

"It turned out that Brad also failed in the end. Lin Su was both disappointed and happy.

He was glad that the secret behind the Water Margin card had not been solved, but such a professional had spent sixty years uncovering the mystery, no, to be precise, he hadn't even found all the mysteries, which was disappointing to think about.

Originally, Lin Su thought that some of them were over, but he didn't expect Brad to write another paragraph on the last page, which seemed to be written after a long time from before.

"After compiling the experimental records over the years, I have a guess that the trigger conditions of the card of Hu Baoyi and Song Jiang are likely to be related to hypergravity. Unfortunately, the human world has not been able to simulate this environment so far, and there are no conditions for experimentation.

The Hundred G Mountain, the seventh continent of the food world, may be the ideal place to cultivate the last card, but unfortunately ......"
