0:00:06.969,0:00:11.479
The talented young herbalist named Xu Xian[br]was in trouble.

0:00:11.479,0:00:13.422
It should have been a victorious moment–

0:00:13.422,0:00:16.212
he had just opened his very [br]own medicine shop.

0:00:16.212,0:00:19.132
But he bought his supplies from [br]his former employer,

0:00:19.132,0:00:22.252
and the resentful man [br]sold him rotten herbs.

0:00:22.252,0:00:25.722
As Xu Xian wondered what to do with this [br]useless inventory,

0:00:25.722,0:00:27.892
patients flooded into his shop.

0:00:27.892,0:00:29.502
A plague had stricken the city,

0:00:29.502,0:00:31.752
and he had nothing to treat them.

0:00:31.752,0:00:33.502
Just as he was starting to panic,

0:00:33.502,0:00:39.242
his wife, Bai Su Zhen, produced a recipe[br]to use the rotten herbs as medicine.

0:00:39.242,0:00:43.113
Her remedy cured all the plague-afflicted[br]citizens immediately.

0:00:43.113,0:00:46.503
Xu Xian’s former boss even had to buy back[br]some of the rotten herbs

0:00:46.503,0:00:48.193
to treat his own family.

0:00:48.193,0:00:52.793
Shortly after, a monk named Fa Hai [br]approached Xu Xian,

0:00:52.793,0:00:55.882
warning him that there was [br]a demon in his house.

0:00:55.882,0:00:58.502
The demon, he said, was Bai Su Zhen.

0:00:58.502,0:00:59.932
Xu Xian laughed.

0:00:59.932,0:01:03.512
His kindhearted, resourceful wife [br]was not a demon.

0:01:03.512,0:01:04.922
Fa Hai insisted.

0:01:04.922,0:01:10.122
He told Xu Xian to serve his wife realgar[br]wine on the 5th day of the 5th month,

0:01:10.122,0:01:12.052
when demons’ powers are weakest.

0:01:12.052,0:01:15.312
If she wasn’t a demon, he explained, [br]it wouldn’t hurt her.

0:01:15.312,0:01:17.292
Xu Xian dismissed the monk politely,

0:01:17.292,0:01:20.152
with no intention of serving [br]Bai Su Zhen the wine.

0:01:20.152,0:01:23.252
But as the day approached, [br]he decided to try it.

0:01:23.252,0:01:25.902
As soon as the wine touched [br]Bai Su Zhen’s lips,

0:01:25.902,0:01:29.122
she ran to the bedroom, [br]claiming she wasn’t feeling well.

0:01:29.122,0:01:32.262
Xu Xian prepared some medicine [br]and went to check on her.

0:01:32.262,0:01:33.712
But instead of his wife,

0:01:33.712,0:01:37.952
he found a giant white serpent with a[br]bloody forked tongue in the bed.

0:01:37.952,0:01:40.512
He collapsed, killed by the shock.

0:01:40.512,0:01:42.482
When Bai Su Zhen opened her eyes,

0:01:42.482,0:01:45.292
she realized immediately what [br]must have happened.

0:01:45.292,0:01:48.522
The truth was that Bai Su Zhen was [br]an immortal snake

0:01:48.522,0:01:50.792
with formidable magical powers.

0:01:50.792,0:01:53.362
She had used her powers to take a [br]human form

0:01:53.362,0:01:56.212
and improve her and [br]her husband’s fortunes.

0:01:56.212,0:01:58.412
Her magic couldn’t revive Xu Xian,

0:01:58.412,0:02:00.822
but she had one more idea to save him:

0:02:00.822,0:02:05.052
an herb that could grant longevity [br]and even bring the dead back to life,

0:02:05.052,0:02:07.400
guarded by the Old Man of the South Pole

0:02:07.400,0:02:12.250
in the forbidden peaks of the [br]Kun Lun Mountains.

0:02:12.253,0:02:15.543
She rode to the mountains on a cloud,

0:02:15.543,0:02:18.303
then continued on foot passed gateways [br]and arches

0:02:18.303,0:02:21.103
until she reached one [br]marked “beyond mortals”

0:02:21.103,0:02:22.783
hanging over a silver bridge.

0:02:22.783,0:02:24.013
On the other side,

0:02:24.013,0:02:27.293
two of the Old Man’s disciples [br]guarded the herb.

0:02:27.293,0:02:29.753
Bai Su Zhen disguised herself as a monk

0:02:29.753,0:02:33.883
and told them she’d come to invite [br]the Old Man to a gathering of the gods.

0:02:33.883,0:02:35.377
While they relayed her message,

0:02:35.377,0:02:37.575
she plucked some leaves [br]from the herb and ran.

0:02:37.575,0:02:40.595
The servants realized they had been [br]tricked and chased her.

0:02:40.595,0:02:43.715
Bai Su Zhen coughed up a magic ball [br]and threw it at one.

0:02:43.715,0:02:45.695
As the other closed in on her,

0:02:45.695,0:02:48.485
she put the herb under her tongue [br]for safekeeping,

0:02:48.485,0:02:51.915
but its magic forced both of them [br]into their true forms.

0:02:51.915,0:02:54.355
As the crane’s long beak [br]clamped around her,

0:02:54.355,0:02:55.985
the Old Man appeared.

0:02:55.985,0:02:59.125
Why, he asked, would she risk her life [br]to steal his herb

0:02:59.125,0:03:00.995
when she was already immortal?

0:03:00.995,0:03:03.745
Bai Su Zhen explained [br]her love for Xu Xian.

0:03:03.745,0:03:07.235
Even if he didn’t want to be with her [br]now that he knew she was a demon,

0:03:07.235,0:03:09.725
she was determined to [br]bring him back to life.

0:03:09.725,0:03:13.575
The two had a karmic connection dating [br]back more than a thousand years.

0:03:13.575,0:03:15.625
When Bai Su Zhen was a small snake,

0:03:15.625,0:03:17.675
a beggar was about to kill her,

0:03:17.675,0:03:19.965
but a kind passerby rescued her.

0:03:19.965,0:03:23.405
Her rescuer was Xu Xian in a past life.

0:03:23.405,0:03:25.885
Touched by her willingness [br]to risk her life for him,

0:03:25.885,0:03:30.905
the Old Man permitted her to leave the [br]mountain with the immortal herb.

0:03:30.905,0:03:35.831
Bai Su Zhen returned home [br]to revive Xu Xian.

0:03:35.832,0:03:37.032
When he opened his eyes,

0:03:37.032,0:03:40.512
the terrified look frozen on his face [br]became a smile.

0:03:40.512,0:03:41.411
Demon or not,

0:03:41.411,0:03:43.811
he was still happy to see his wife.
