Jason felt like his body was a little strange lately.

"Shhh

There was another cramp in his calf, this was the third cramp today, the first cramp he almost fell from the air, just without warning, suddenly cramped, Jason had to stop training and wait for the cramp to pass.

"Master Jason, what's wrong?"

When Alfred walked into the training room with a glass of hot milk, he found that Jason was not training as usual, but sat on the floor and asked with some concern.

"Oh . . . It's okay..."

Jason rubbed his aching calf without a trace, took the milk from Alfred and drank it. Alfred thoughtfully didn't continue to ask, a boy of this age always had a lot on his mind.

Jason thought it would be over quickly, but the pain showed no sign of subsiding, and it was getting worse. After waking up from a dream one night with an ant-biting itch from his knee, Jason thought he might need a check-up.

"Report it to me!"

As soon as Jason got off the check-up table, he was impatient to see his health report.

"Oh, Master Jason, please don't be in such a hurry, it will take some time for the report to be typed"

Alfred was amazed at Jason's behavior, he had never cared about the report of such a routine medical examination before, and if it wasn't normal, Bruce would definitely have told him.

Jason crouched next to the printer, carefully looking at his medical report.

The heart rate is faster than normal, the hormone is a little high, the body fat ratio is low, and the weight is thin.

"Is there anything you care about?"

Seeing Jason staring at the report so seriously, Alfred asked with some curiosity.

“.. No.. No... Nothing."

Everything is normal in the physical examination report of the Bat Cave, and the conclusion of the report of the school's routine physical examination is also normal. But the uncomfortable pain in the cracks of the bones did not mean to abate in the slightest. Jason frowned and stared at the paper report in his hand, eager to stare at a hole in it.

"What's wrong with him?"

Jason's dejected back caught Bruce's attention.

"Boys at this age are always a little sentimental, maybe they are a little worried that they won't grow tall."

Alfred, who raised Bruce and brought up Dick, is authoritative.

“...... It should be soon, the report shows that the male hormone levels in Jason's body are starting to rise, and it should be almost starting to enter the development period"

Jason's age has always been a mystery because of his too thin physique, even though he was severely malnourished due to his abnormal diet in the past, Jason's physique is still too thin compared to his peers.

Bruce was suspicious that Jason's birthday registered in the official database was written by his irresponsible daddy. However, through the most advanced equipment in the Batcave, although there is no way to accurately date the date of birth, it should not be too wrong that he and Dick have a time difference of about two and a half years. From this point of view, the time when the man registered is not too far off.

"Oh, then I should start needing to re-prepare my clothes for Master Jason."

Jason didn't know anything about the conversation between the two men in the Batcave, and he was sitting in his room searching the internet for all the information about joint pain.

"Hopefully it's not a nuisance"

With the help of an advanced and well-developed network, all cases of pain inside the calcaneus bone were soon listed.

Gout, certainly not. It hurts, but it's not enough to make it impossible to walk. Moreover, in the case of gout, the urea content in the blood test should be indicated, but his blood test is normal.

Arthritis, considering that I used to wear very little, and the room I lived in was also a cold environment, this is a little more likely. But isn't it more likely that Dick will get this disease than he does? That guy used to run around bare-legged when he was a kid.

Jason looked at the information from the computer with a headache. Each one was somewhat similar to his leg pain, but not exactly the same.

Eventually, his eyes were fixed on a paper on early-stage bone cancer.

Bone cancer is the most terrible and serious of all bone diseases, and the survival rate is extremely low, and the pain is also quite great. And once this disease is discovered, it is basically advanced, and the early symptoms vary from person to person, but the early symptoms of some people are joint pain.... Especially at night......

“...... Isn't it....."

Probably not, Jason kept mentally denying this possibility, if he had this disease, it would be impossible for Bruce not to detect it during his routine physical examination, and he didn't feel anything like a lump on his knee.

Jason's hand subconsciously touched his knee to make sure he didn't touch anything else from inside.

"Master Jason?"

Alfred knocked on the door, waking Jason up in a daze.

"Oh, it's patrol time"

Jason realized that it was now past patrol time, and hurriedly ran from the room towards the bat cave.

Alfred was a little uneasy that Jason would forget the patrol time, and when he saw that Jason had not had time to turn off the computer, he hesitated but walked over anyway. After seeing what's on your computer:

"Oh my goodness"

Tonight's night watch didn't go well for Jason, with the occasional throbbing pain in his calf and the dull pain in his knee making it difficult for him to concentrate. In addition, reading those messages made Jason's mind full of irritability, and because of irritability, he became extremely ruthless.

"Robin!"

Batman's voice was like a basin of ice water in the winter that woke Jason's sanity, and Jason found that the thug he had beaten was completely speechless.

"What's wrong?"

Bruce knows the ruthlessness in Jason's bones, and from the unconscious words and behaviors in daily life, that kind of thing always seeps out of Jason's body intentionally or unintentionally. Whether it was something that Jason was born with, or whether it was later in life that had carved this trait into the boy's marrow, he didn't know.

But Jason's blatant display of this trait today still caused Bruce to worry.

Glancing at the stunned thug, Jason stopped his actions and lowered his head without the slightest intention of saying anything.

The two men remained silent until the Batmobile returned to the parking space in the cave.

Alfred walked over and saw Jason, who had been silent with his head down, and asked with some concern:

"Is there anything wrong with Master Jason?"

“... Nope"

"I saw what you watched again, please don't look at me like that, you didn't turn off your own phone"

Alfred's words also caught Bruce's attention, and Jason's performance today could be described as irritable, not at all like him.

"What happened?"

"Master Jason is browsing all the knee and bone ailments"

Hearing Alfred say this, Bruce turned his head to look at Jason, and asked in as slow a tone as possible:

"What's wrong with that?"

“... Knee pain"

Jason pouted.

Hearing Jason say this, Bruce and Alfred exchanged glances and then asked:

"How long has it been hurting?"

"Just these days"

"Very serious"

"Hmm"

"How serious?"

"Woke up in pain at night"

"Are there any other symptoms?"

"I'm going to have cramps"

Hearing Jason say this, Bruce raised his eyebrows, stretched out his hand and rubbed Jason's head and said:

"Don't worry, that's a good thing, but I'll give you a check-up just in case."

"A good thing?"

Jason didn't understand why pain was a good thing.

"Everyone's height will grow suddenly during the growth period, which requires bones, blood vessels, nerves, and muscles to grow in large quantities in a short period of time, so it will cause pain, although everyone's pain is different, but they will feel pain, we call this phenomenon growing pain"

Jason couldn't digest what Bruce had explained to him.

"Congratulations, Master Jason, you're going to grow taller from now on"

Alfred looked at Jason, who was stunned, and gave him the final answer.
