My brother is so cunning

Chapter 1014 The Law of Time
The Law of Time is the most important of all the laws of Heaven.

In the Three Realms, the only powerful being who once possessed the law of time was Zhujiuyin, one of the Twelve Ancestral Witches.

Despite possessing the near-invincible ability to manipulate time, he was still defeated in the ancient war between the Lich King and the Demon King, resulting in his death and the loss of this power. This power was also taken back by the Heavenly Dao and was never bestowed upon any supreme being in the Three Realms again.

It is evident that if the Heavenly Dao has self-awareness, it must value and fear the power of time quite a bit. The death of Zhu Jiuyin may not have been due to the great power of the Demon Clan's Celestial Star Array, but rather the interference of the Heavenly Dao's will.

After the Heavenly Dao reclaimed the authority over time, even the most powerful beings in the Three Realms, who cultivated to the extreme, could only obtain the so-called "predictive" ability. Moreover, these predictions were only speculative, and because they were concealed by the Heavenly Dao, they would never accurately reveal the full picture of the future.

This is what is meant by "heavenly secrets cannot be revealed".

If this technology is chosen, Wen Rui can foresee great risks. On the one hand, there is the "flashpoint paradox" caused by the disruption of time stability, which could very likely trigger spacetime collapse and turn the entire primordial world into nothingness.

On the other hand, the Heavenly Dao itself, or the guardian of the Heavenly Dao, Hongjun Daozu, would definitely not sit idly by and would nip the threat in the bud before Wen Rui abused this weapon.

The system task of having Wen Rui destroy the three religions was already outrageous enough. To deal with the saints of the three religions, he abused the weapon of time, which attracted the intervention of Hongjun or even the Heavenly Dao itself. Even if the great god Pangu were alive, Wen Rui would not be able to withstand it.

It should be noted that even Pangu, who cleaved the heavens with an axe, ultimately died from exhaustion.

All three technologies are top-tier, but unfortunately the system only offers one option, leaving Wen Rui once again struggling with decision-making difficulties.

Bioconversion chambers and time grenades are undoubtedly better, but they also have their drawbacks and risks.

The misuse of biotransformation chambers can indeed unleash the full potential of all living beings, making everyone a dragon, but it will also lead to the continuous deterioration of the life essence of all living beings.

There are gains and losses. Although potential is stimulated, the upper limit of potential continues to decline. After dozens or even hundreds of generations of iteration, even if one is born as a celestial being, the original energy of life may be less than that of a bacterium. One's lifespan ends within seconds of birth, and the five signs of decay begin.

The time grenade might attract the intervention of the Dao Ancestor Hongjun. That Dao Ancestor can poison a saint with a single pill. Even if Wen Rui can kill a saint with the time grenade, he would be reduced to ashes in the blink of an eye when facing the Dao Ancestor Hongjun.

The planetary shield comes at the lowest cost, but unfortunately it is a passive defensive technique. Even if it can withstand a saint's full-force attack, what if the saint attacks again after the first attack misses?

The power of a sage is incomparable to that of an ordinary deity. Even a Primordial Golden Immortal would have their mana bar emptied if they unleashed a strike with the power of a stellar explosion.

Sages probably don't have such limitations. They could recreate the earth, fire, wind, and water, and even rebuild the primordial world. How much energy from the explosion of billions of stars would that require?
After much deliberation, Wen Rui made a firm decision and chose the Time Grenade Technology.

In an instant, a flood of information rushed into his mind. Wen Rui was momentarily stunned, and when he opened his eyes again, a fleeting glimpse of an hourglass appeared in his pupils.

Wen Rui raised his hand, and countless golden nanounits gathered in his palm. Under his control, they coalesced into a cluster, constructing an extremely precise structure.

In the past, Wenrui could control the nano-unit construction equipment in less than a second, even if the equipment design drawings were very complex.

This time, however, it took a full hour for a perfectly smooth golden ball to gradually take shape in his hand. This tennis ball, about the size of a tennis ball, was the prototype of the time-reversal grenade. Once this grenade exploded, everything within a one-kilometer radius would rewind to one minute prior, and no form of attack would affect the time reversal.

Because the explosion of the time-reversal grenade would disrupt the continuity of the timeline, Wen Rui dared not test it lightly.

If Wen Rui were to casually try something, and a seemingly unapproachable old man suddenly appeared before him, roaring "You beast, how dare you!", he would be completely out of control.

However, Wen Rui could also imagine the practical application effect of this grenade, which was the effect of the Sharingan "Izanagi".

No matter how severe the injury, even if it means losing one's life, as long as the grenade's explosion time is preset, one can go back to the moment before being hit, thus devising a solution and taking further action.

Alternatively, after rewinding, immediately detonate another time-rewind grenade to advance the timeline to before the opponent launched their attack, allowing for the most accurate prediction and counterattack.

It's like having countless extra lives, and being able to reload and start over at will.

Unfortunately, the risk was too great, and Wen Rui dared not use it unless absolutely necessary.

When things really get to the point where a sage could crush you with a single finger, then there's no need to worry about whether it will attract the intervention of the Dao Ancestor Hongjun.

Attracting the attention of Hongjun Daozu might not be a bad thing. Daozu has explicitly forbidden the three religions from fighting amongst themselves. If a saint bullies Wen Rui, a fourth-generation junior, the punishment won't just fall on Wen Rui's backside.

This is like giving yourself a final insurance policy, which is much more reliable than a planetary shield.

If we don't consider the possibility of fighting to the death with a saint in the future, then of course the planetary shield is better. With the planetary shield technology, Wen Rui would be invincible below the saint.

Even if he were besieged by a group of Primordial Golden Immortals, his stored energy would be enough to withstand the immense power of countless stellar explosions they would unleash. If Wen Rui wasn't killed by the explosions, the entire Primordial World would be smashed to pieces.

Another important reason for choosing the Time Reversal Grenade is that the design data for this weapon involves knowledge related to the laws of time.

With his level 5 intelligence, Wen Rui could reverse engineer the time-rewind grenade, thoroughly understand the principles behind altering the flow of time and cutting and splicing timelines, and thus develop more time-related technologies.

Back then, Wen Rui didn't get any time-related technology from Lao Rui. In Lao Rui's own words, it wasn't that he didn't understand it, given his level 10 intelligence; he just didn't bother to study it.

The law of time is a law that even a very few sages have not mastered. If you want to fight against a sage, or even defeat a sage, the only way is to start with the law of time.

Even if Wen Rui obtained other laws of power through system lotteries, it would still be far less thoroughly understood and skillfully applied than by the ancient sages who had studied them for countless years.

Even if reverse engineering cannot fully comprehend the laws of time and achieve arbitrary time travel, even if it obtains the technology to slow down or stop time, it can still catch the saints off guard.
