Why was Jinling only 15 years old after Wei Wuxian died?

First of all, Ling Jin is 16 years old. (Without members, screenshots can't be made. ) The original work is as follows:

1. "Not long ago, a blue flying sword destroyed your fairy net."

Jiang Cheng said, "How many are broken?"

"... all ..."

More than 400!

Jiang Cheng was furious.

I didn't expect this trip to be so unlucky. At first, he came to support Ling Jin. This year, Ling Jin is 16 years old, so it's time to make a debut and compete with the younger generations of other families.

2. Blue forgot the machine: "Age Geometry, who are you?"

These two questions are testing Lai Ling's identity. Wei Wuxian knows that he will get an unusual answer: "How?"

Lan forgot the plane and said, "Sixteen years old, from Lanling."

Wei's envious face suddenly changed.

The soul invited by "Wen Ling" turned out to be Ling Jin? !

Secondly:

The time on the petition is very chaotic, that is, 13 and 16 are exchanged back and forth, which is not very clear. Mainly, the past life in the original work is a memory space, which accounts for a few chapters, especially few. The author introduces the plot without specifying the year and month. Every time it appears, the vocabulary is very vague, such as the word "rectification". In the TV series, the past lives accounted for half, all of which were made up by writers. He made sure that all the key events in the original work happened, and the plot was complete and reasonable, but the schedule was a bit chaotic, which might be related to the post-editing.

The original text is very clear. Wei Wuxian died in 13, 16. If you insist, Wei Wuxian was bloodied all night. Lan Zhan sent him back to the mass grave and fought with the elders at home. He was imprisoned for three years (in fact, he was seriously injured). Three years later, Lan Zhan just came out and heard that Jiang Cheng led people to surround the mass grave and Wei Wuxian died. So they haven't seen each other for 16 years.

Note that in the original book, Wei Wuxian died in blood night three years later, when his family besieged mass graves. However, after a bloody night, he was ordered to die, and then he went to a mass grave to surround the remnants of the Wen family, thus eliminating the three years in between.
