I Am A Matchmaker on Taobao - Chapter 116:

One day, Yoichi who grew up while not knowing his parents has received the news of his father’s death. His father left behind a testament——which said he is to pick only one out of five ‘little sister candidates’?!

Ye Xuan came from a normal but extremely wealthy family. Yet, one day, when he woke up, he realized that he had been transmigrated to a fantasy world.

He was prepared to train and embark on an adventure, but he quickly learned that he had actually become the young master of Thousand Realms, the biggest trade company.

His father even let him inherit more than trillions of spirit stones.

“Are you serious? I’m sick of being rich!” Ye Xuan complained.

Fortunately, he had awakened a system that would make him stronger by spending money.

With that, he used the Grade 9 Celestial Pill to feed his dogs.

He used the famous painting that contained the will of the Supreme Sword to start a fire.

He used the Five-elements Divine Talisman to clean his ass.

And yet, he still had much more to spend. He then decided to join a clan that no one had even heard of.

He spent thousands just to see the saintess of the clan smile.

He built a pill alchemy workshop and gave out high-grade celestial herbs for free, and yet, one of the disciples who had never made a single pill was actually talented and was able to create the high-grade celestial pills.

When he started a dueling competition, he bet a lot of his money on the weakest contestant.

However, that contestant had actually awoken the Ancient Holy Body during the fight and was able to fight 100 men on his own.

“You sure are my son. You are as talented as me when it comes to managing a business!” his father complimented.

“This man is so cool when he spends his money!” exclaimed the saintess.

In the history of geology, more than 500 million years ago, there was a period of the Paleozoic Era known as the Cambrian Period. This period, being the first period of the Paleozoic Era, does not only have a significant meaning for geological research, but also is the most insane, splendid and mysterious period in paleontological history.

Before the Cambrian Period, the Earth’s species were relatively monotonous. When the Cambrian Period started, just after millions of years, which is a relatively short period of time in terms of geology, all kind of species on Earth suddenly evolved wildly. Countless of invertebrates, arthropods, mollusks, brachiopods, annelids etc. have appeared on the planet without any warning, greatly enriching the diversity of the Earth’s species. This million years period is known as the “Cambrian Explosion”. And after billions of evolutionary years, the Earth today blooms with diverse lives.

The cause of the Cambrian Explosion is a huge mystery and also the biggest paradox of Darwin’s theory of evolution.

What if… the Cambrian Period is coming back in this era when human civilization has already conquest the entire planet, and the global species will once again evolve wildly, what kind of challenge will this planet encounter? What kind of fate will humans, who are falling from the top of the food chain, face?
