"But since I've just reached the third cosmic speed, my current movement speed is still far from reaching the fourth cosmic speed, roughly 103.1 kilometers per second lacking. Just saying it fills me with an unreal feeling, as it's truly beyond the reach of my fourth tier."

To some extent, Zhang Yanhang suspects that even if he were to advance to the fifth tier, he might still not reach such speeds, considering that the fourth cosmic speed, when converted to Mach, is roughly three to four hundred Mach, while his current normal speed doesn't even reach thirty Mach.

Therefore, while achieving the first cosmic speed, second cosmic speed, and third cosmic speed was quite simple, the fourth cosmic speed is far from a minor goal, instead it will be a long-term objective.

"If I convert my speed with boosted spiritual energy into kilometers, I can already move 60,754 kilometers in one hour, which means even the mere 40,000 kilometers of the equator can't contain me. I can run one and a half laps in an hour."

Previously, Zhang Yanhang needed nine and a half hours to reach the moon, but now he can get there in just six and a half hours, cutting down a full three hours, allowing for a round trip to the moon in just thirteen hours.

Given this situation, Zhang Yanhang is confident that before advancing in rank, he can make a round trip to the moon in a duel. After all, he still has one movement speed coin waiting to be synthesized, so achieving this twelve-hour round trip target should pose no problem.

"The only pity is that the increased hunting efficiency, which came with the improvement in movement speed, cannot be fully utilized, since there are only fifty-one monsters left in the entire Umbrella Biochemical Test Field."

Based on previous experience, Zhang Yanhang can somewhat estimate his current hunting efficiency, which can increase from clearing six square kilometers per second under normal conditions to about eight square kilometers per second, enhancing hunting efficiency by one-third.

After focusing on movement speed, Zhang Yanhang also shifts his attention to attack speed, especially his punch speed. After receiving a whopping 230% attack speed bonus, his punch speed, enhanced with spiritual energy, has now surpassed one hundred Mach.

If he further enhances with spiritual energy in terms of strength, doubling from 14,990 tons to 29,980 tons, then using the kinetic energy formula alone, his normal attack might already achieve 1,8241,2329,0544,0000 joules, equivalent to 1.82 quintillion joules.

When converted to TNT equivalence, that's roughly equal to 4.36 million tons of TNT, meaning the cumulative energy from the explosion would be equivalent to that from combining 4.36 million tons of TNT.

In other words, Zhang Yanhang has now moved from the stage of megaton equivalence to the multimillion-ton equivalence, becoming truly akin to a powerful nuclear bomb.

Nuclear bombs of this scale are rarely manufactured, as most nuclear bombs maintain under megaton equivalence, relying instead on quantity to cover larger areas.

For example, three detonated simultaneously could cover an entire large city, offering a far more cost-effective solution than delivering a single multimillion-ton nuclear bomb directly, achieving similar effects. After all, for ordinary humans, even if not within the shockwave range, they might still be killed by high-concentration nuclear radiation.

According to the relevant radius formula, a nuclear bomb with a 4.36 million tons equivalence has a direct kill radius of about 11.4 kilometers. Yes, radius.

In terms of actual coverage, Zhang Yanhang can now strike an area covering roughly 408 square kilometers with a single punch.

In other words, for a region like the Umbrella Biochemical Test Field, which covers only 40,000 square kilometers, Zhang Yanhang could obliterate it entirely with just a hundred punches, ensuring nothing remains.

Perhaps only the Lucky Slot Machine, Evaluation Settlement Treasure Box, and Achievement Vending Machine, which are protected by the rules of the Ashen World and immune to destruction, could survive.

But realistically, Zhang Yanhang can't truly do that, as such speed would likely lead to more time-consuming cleanups than normal procedures. After all, it would require painstaking efforts to dig out all the treasure boxes buried deep underground.

It's important to note that under normal conditions, the retrieval of surface-level corpses and dropped treasure boxes requires splitting time evenly with the hunting process. If they're all struck deep underground, who knows how long it would take to gather them all.

Additionally, the extra attack triggered by his previous punch is a good example, as even the enemy was pulverized, mixed with surrounding rocks and soil, unable to be separated.

Thus, this method of hunting monsters would inevitably waste their corpses. His stomach space is ultimately limited, and when the powdered corpses mix extensively with the earth's layer, he can't load much.

Monster corpses are linked to his body's growth rate, so from many perspectives, Zhang Yanhang typically wouldn't adopt this hunting method under normal circumstances.

Perhaps this method could be considered in the future when hunting monsters in the Permanent Teleportation Channel, as those monsters don't drop treasure boxes, and sacrificing their corpses alone might warrant considering quick clearing.

Apart from punch speed, the Six Roots Pure Soul Gun naturally also undergoes changes under the influence of attack speed bonuses.

Originally, Zhang Yanhang's Six Roots Pure Soul Gun's cannon bullet firing speed was about 4,540 rounds per second, but now with the boost from attack speed coins, it's increased to 6,840 rounds per second, meaning the firing speed has further increased by 2,300 rounds per second.

"Previously, emptying a magazine of ten thousand cannon bullets took approximately 2.5 seconds, but now it's shortened by one second, taking just 1.5 seconds to clear a magazine."

However, adhering to the principle that compression becomes harder as progress continues, though the difference is only 0.5 seconds, this can't be further reduced by simply acquiring one more attack speed coin."

Zhang Yanhang remembers that last time he synthesized an attack speed coin, it reduced the time by 0.3 seconds. This time, a combination of four attack speed coins only managed to cut down by one second, averaging a reduction of 0.25 seconds per coin.

Thus, though 0.5 seconds seems little, even with the current reduction efficiency, at least two attack speed coins would be needed, particularly considering the efficiency can't be maintained. So realistically, at least three more attack speed coins would be necessary.

Forget three attack speed coins, even gathering one more is challenging for him now. So while achieving the small goal of reducing the magazine emptying time to less than two seconds, there's certainly no way to further reduce it to under one second."

The ambition to lower the magazine emptying time to under one second will have to wait until advancing to the fifth tier."

Alongside the increase in firing speed, the Six Roots Pure Soul Gun's cannon bullet flight speed has also improved. The bullet's flight speed has successfully grown from the original 109 Mach to 164 Mach, increasing by a whopping 55 Mach speed, about a fifty percent boost in flight velocity.

"According to the relevant kinetic energy formula, the current flight speed of 164 Mach for the cannon bullet is equivalent in power to 2.3 times that of its previous state at 109 Mach."

Calculating 24 Mach in its initial state, it now has increased from the original 109 Mach by 20.6 times to 46.7 times, a fierce increase of 26.1 times."

Zhang Yanhang's own speed is barely under 25 Mach, yet here it's casually increased by 55 Mach, over twice his own speed. He can only acknowledge that kinetic weapons function that way: if the speed isn't fast enough, you can't hit the enemies, let alone cause damage.

After dealing with the attack speed coins and movement speed coins, Zhang Yanhang feels he has nothing to do again. He's finished assessing everything from the drop treasure boxes, whether it be soul points, talents, or artifacts and equipment.

After all, he didn't get any new drop treasure boxes this time, so naturally, he didn't receive anything new, therefore the attack speed coin fragments and movement speed coin fragments he just checked were the last items he needed to evaluate.

"And since there is nothing to do, next up is clearing the last fifty-one monsters in the Umbrella Biochemical Test Field."

But before starting the monster hunt, Zhang Yanhang first opened his data panel to take a glance.

"How should I say it, this time there's no upgrade in talents or skills, nor improvement in attribute values, thus my attribute list, talent list, and skill list remain unchanged, only the soul point balance and Life Value limit have shown some change."

Zhang Yanhang remembers last time he had less than thirty-eight million soul points left, whereas now he has nearly one hundred million soul points, almost 2.6 times more than last time, quite a substantial increase.

But this is rather normal, after all, Zhang Yanhang cleared a quarter of the Umbrella Biochemical Test Field monsters in one go, and without upgrading skills this time, hence without soul point consumption, acquiring such a balance in soul points is exceedingly normal.

In fact, if Zhang Yanhang had always held onto them before, he would have long breached over one hundred million in soul points by now.

Actually, according to Zhang Yanhang's estimation, the entire Umbrella Biochemical Test Field provided him with at least two hundred million or even close to three hundred million in soul point returns.

If you wonder how those one hundred million plus soul points were spent, naturally they were all used in upgrading skills, after all, casually upgrading one skill costs twenty million soul points, and Limitless Universe Skill consumption exceeded forty million soul points.

Therefore, from this aspect, even one hundred million soul points are not that substantial at Fourth Tier, at most only enough to upgrade Limitless Universe Skill plus three other professional skills, otherwise Zhang Yanhang wouldn't have waited until the Umbrella Biochemical Test Field was nearly entirely cleared before finally accumulating some soul point balance.

"Besides changes in soul points, the remaining change lies only in the Life Value limit, Shield Value limit, and Energy Value limit."

This time my Energy Value limit didn't gain any growth, instead decreased by eighty-seven points due to dual selection consumption, while at the same time, my Life Value limit grew thanks to the Dark Gold Quality Life Ring +7, resulting in greater divergence between the two."

Zhang Yanhang remembers last time the gap between Energy Value limit and Life Value limit was only 2.46 times, but now it's been widened to 2.49 times, increasing the disparity by 0.03 times.
