After 6 years
Both Tang san and Tang ling grew up together and were inseparable and Tang san taught his brother Tang sect's techniques as he doesnt know Tang ling is adopted and Tang san is the little brother here and he is dependent on Tang ling and his father but mainly his brother.
Although Tang ling(Protagonist of our story) knows about him being adopted and the future events and has plans to return to his clan at the right time as his mother had explained about the situation to him thinking he would not understand as he was a baby but our protagonist remembers it all clearly and he has a system which can give him rewards based on tasks completed and how perfectly it is completed.
Tang Hao has become less alcoholic as he drinks only on specific days of a month it is because
Once he was heavily drunk and a glass bottle fell and broke and both Tang san and Tang ling stepped on it(A system task to stop Tang Hao from drinking in future) and both Tang ling and san started crying due to getting hurt and were bleeding Tang Hao woke up due to the notice and to his horror saw both children bleeding and with his Titled daolao cultivation should have stopped it him self but due to getting drunk(He allowed the alcohol to take effect) he was not able to and he took them both in his arms and carried them to Nuoding city for treatment and stopped drinking alcohol not totally but reduced it it once or twice a month.
Now Tang ling is taller than Tang san and has well defined muscles not ripped but well defined and under his care Tang san is also a bit taller than his anime counter part but also is a bit muscular not at his brother's level but a bit more than normal children.
During all these years Tang Hao has not spent any of the money given to him for taking care of ling'er but has kept it safe in a cave behind waterfall with Ah Yin .
He has taught hammer techniques of Clear Sky Clan to both Tang san and ling and he was surprised by how quickly both of them had mastered it to be more accurate how quick Tang ling had mastered it he under stood Tang san as he was his biological son but for Tang ling to master it he must have immense talent or come from a blacksmith family.
During this period in Ape clan
No one except Ra Bing knows that her son Yuan ling is still alive and safe somewhere in the world .
Yuan Tien and Yuan Shen both became extra careful with Yuan Ting and practically spoiled him as Ra Bing did not stop them.
Under both Father and Grandfather 's care Yuan Ting had lived a carefree life but each year on his birthday they all would be sad and grieve infront of a tombstone on which is a name of a family member who he has not met or heard about in his whole life not from clan members , not from his father, not from his Grand father and each time he asks about it they all either ignore it like they didn't hear him or divert him from the topic.
Once when he first came to the clan's graveyard he was happy and running around when his mother bet him on his head and took away all his presents and cancelled his birthday party.
Only after alot of convincing from both his father and grandfather did he get to have his birthday party and since then he became curious about the person who the grave belonged to and hence his asking for all the family members about the person who the grave belonged to and all led him to his mother and told to ask her about it and since everyone in the clan had brought him here his mother under his relentless persuasion finally agreed to tell him about the person who the grave belonged to once he turns 6 years of age and awakens his martial soul.
She hoped he would have forgotten about it as she didn't want to lie to her son about him having a twin brother and him dieing at his birthday.
The day before martial soul awakening
Holy Soul Village
Tang san and Tang ling speak to each other about tomorrow "San'er no matter whatever martial soul you awaken I will always protect you" Tang ling said while cutting his hand and doing a blood oath.
It moved Tang san and he too took a blood oath "I will also protect big brother forever " they both hugged each other.
In the Ape clan
"Tomorrow is the day when I will learn about the person who the grave belonged to and mommy you can't go back on your word" Yuan Ting said to his mother.
"Okay sweety now go back to sleep as we have a big day tomorrow where you will awaken your martial soul just like father and grandfather an ape martial soul " she said putting her son back to sleep.
In Holy Soul Village
Tang Hao was pretending to sleep and he heard the children taking oath and after they slept he got up and silently went to meet his wife Ah Yin without making any noice and upon reaching there he spoke with her for awhile and went back.
In Ape clan
Just like Tang Hao, Ra Bing spke with her husband Yuan Ting.
The day for which both the parents and children were waiting for had come the parents anxious about the children's reaction when they learn about the secrets which they are about to reveal and children preparing themselves for their martial soul awakening and wondering what kind of martial soul they were about to awaken so much so that they could not even sleep properly.
