Also, after Zhang Yi healed them and the pains disappeared Zhang Feng felt as if he had become twenty years younger, he felt no discomfort anymore and felt much lighter, even some pains he had gotten used to after that.
Mary suffered the most because she was not used to feeling such pain, but she also felt much better after she stopped feeling pain, which they didn't know was that Zhang Yi had cleared her soul and some meridians they didn't even know that existed.
After that, they could cultivate much more easily than many far more talented cultivators who were younger than them, of course not even the biggest sects had anyone like Zhang Yi to do something like that and even if they had they would never ask for one So talented elders do something like that.
Zhang Yi let his parents rest for a day and the next day prepared a high-level medicine that had no medicinal poison, it was rare, expensive and difficult to do what he created for his parents.
Zhang Yi created something like a bathtub for both of them to use and they sat on something worth thousands of high-end spiritual stones, only after that did Zhang Yi ask them to start cultivating.
If Zhang Yi used something like this for him, it could take less than 2 days to pass a cultivation level, but of course, his parents didn't have a talent anywhere near what Zhang Yi had and it took 1 month even with all the help Zhang Yi had was giving.
After reaching the second level of the Body Refinement they could feel that everything Zhang Yi had said was true, Zhang Feng felt that he was the strongest man of all in his army and even Mary was just slightly weaker than him.
As someone who was in the army and always wanted to get stronger Zhang Feng was much happier with this, Zhang Yi continued to get stronger as he helped his parents, too and waited for his master to come out of cultivation alone.
After another 8 months, his parents reached the Qi Accumulation realm, so their lifespan was much longer and their age became a minor problem, at that time Zhang Yi turned 18 and advanced twice on cultivation. qi and his body refinement and once in the cultivation of his mental energy.
So he had reached the initial layer of the third level realm of mortal tribulation and the eighth realm of body refinement as well, and Zhang Yi had reached the advanced layer of the fourth level of the eighth realm of mental energy, so his cultivation of qi was approaching his mental energy cultivation.
After these 9 months of cultivation his parents completely believed in Zhang Yi now, they could feel that their body was completely different from what it was 9 months ago.
Zhang Feng believed in Zhang Yi that after a certain cultivation realm they could live for tens of thousands of years and spend much more time as a family, moreover, after creating a cultivator understanding and having the most developed martial heart Zhang Feng no longer missed the land.
After those 9 months with Zhang Yi using the special domain using the 10 laws, he had supreme understanding and also the mental energy his parents' cultivation base was perfect and Zhang Yi could let them cultivate without his help after that.
Since Zhang Yi had opened and cleaned all their meridians 9 months ago the Qi Accumulation realm was easy for them to pass without Zhang Yi's talent and at an older age, they only needed 3 months to advance each layer.
So in 6 years Feng Ran had finally come out of his isolated cultivation and reached the seventh level of the Emperor Realm, Feng Ran felt better and more confident in furthering cultivation in those years.
Along with Zhang Yi, he felt that he had more inspiration to cultivate, perhaps in those 400 years, he could reach the divine realm with Zhang Yi's help and thus have enough power to fight against the organization of the soul eaters.
With Zhang Yi's help and some unexpected talent, Zhang Yi's parents were able to get to the initial layer of Core Creation realm, of course, they had already started using Houtian realm cultivation pills, but even so, their cultivation speed was faster than many normal cultivators.
This helped Zhang Yi to know that the technique he had used to help his parents cultivation faster also served to help his children in the future to become cultivation geniuses.
Even if they could not cultivation as fast as it would still be very fast, after they reached the Core Creation realm before age 50 as they did not yet, their age became suitable for cultivation.
A Core Creation realm cultivator can live for hundreds of years and being 50 is considered to be the adolescent realm of this realm cultivator, this made Zhang Yi surprised and happy because now they could possibly reach the Realm of Emptiness and live hundreds of thousands of years.
Of course, Zhang Yi knew this was almost impossible to do and that getting to the Soul Birth realm was already very good for them, but as a son, he wanted to believe that his parents could live for many years.
After these 6 years Zhang Yi can reach the sixth level advanced layer of the eighth realm of mental energy, in these 6 years he can also reach the initial sixth level layer of the eighth realm of body refinement and the sixth level of the mortal tribulation realm as well.
After these heavenly tribulations, he passed his spear also got stronger and stronger, in those years Zhang Yi can also completely regain his understanding of all laws before turning back time and being complete again.
As Zhang Yi put his special eyes back on him that helped him control the laws of space and time and his mental energy more easily, he knew well that he couldn't advance further into his supreme understanding before reaching the realm of Soul. Refinement, but he had to get used to his eyes again.
So now beyond cultivation, Zhang Yi recovered all he had before going back in time when he met his wives again his life would be even more perfect than before and it would be worthwhile to use the laws of time and suffer from heavenly tribulations even stronger this time.
When Feng Ran saw how Zhang Yi and his parents had become so much stronger in these almost 7 years he was surprised once again, he thought his parents would be lucky if they got to the Spiritual Sea realm in this life because of the advanced age they began to cultivate.
But in less than 7 years they started to cultivate and were already in the Core Creation realm, Feng Ran also knew that this was not because of their talent but because of something that Zhang Yi did.
Of course, he figured they both had a lot of talent for cultivation because of Zhang Yi, after all, in order for him to be born so talented his parents had to have at least some talent for the rules of the spirit world.
And Zhang Yi's advance in his cultivation still surprised Feng Ran, even though Zhang Yi said he cultivated quickly and it was still impressive to see how Zhang Yi managed to advance 6 layers in the eighth mental energy realm in just 6 years.
He knew well how people who cultivated mental energy took longer to cultivate mental energy than to cultivate qi and body refinement, and he could still see that Zhang Yi was not using cultivation resources, even though it was the second time that Zhang Yi cultivated was still impressive.
