"It seems that upgrading the Four Great Emptiness Purifying World Fist still requires other Orange Quality Weapons or Equipment."

Fortunately, he's only short of two pieces. If it were more, Zhang Yanhang might lack confidence, but with just two more to go, it's not too daunting. He estimates that piecing together bit by bit should surely complete the set.

"Although I can't fuse three pieces of Orange Quality Electromagnetic Energy Pump +5, I still need to give it a try, since I'm precisely short of these last two Electromagnetic Energy Pump +5 right now."

As he spoke, Zhang Yanhang placed sixteen pieces of Electromagnetic Energy Pump +4 into the Alchemy Array and began the fusion.

As the Electromagnetic Energy Pumps gradually turned into liquid and merged together, Zhang Yanhang successfully achieved a breakthrough this time.

"One Electromagnetic Energy Pump +5 can provide an additional 20% Physical Recovery Speed Bonus, and two combined provide 40%, which should significantly shorten the recovery time."

After completing the fusion, Zhang Yanhang immediately replaced the Electromagnetic Energy Pump +4 in his arm with these two Electromagnetic Energy Pump +5. In doing so, all four equipment slots in his arm were now occupied by Orange Quality Electromagnetic Energy Pump +5.

"Previously, it took ten hours to restore a full stamina bar, but due to the increase in stamina limit from upgrading the Talent, it unfortunately decreased again to thirteen and a half hours.

But after equipping the two new Electromagnetic Energy Pumps +5, the recovery time is again reduced by about an hour, meaning a full stamina bar can now be restored in twelve and a half hours. However, I'm still two and a half hours short of achieving my small goal."

Zhang Yanhang's attitude remained unchanged, feeling it's hopeless until the Fifth Tier, as there are indeed no additional channels left for improvement in the Fourth Tier.

Calculating by needing a 100% Physical Recovery Speed Bonus to reduce two and a half hours at 20% for thirty minutes, unless he can grow an extra pair of arms to equip another Electromagnetic Energy Pump, how else is he to gather such a large Physical Recovery Speed Bonus?

After tallying up the Life Ring, Neck Potential Activation Device, and Electromagnetic Energy Pump, Zhang Yanhang shifted his focus to the Coin Fragments he most eagerly anticipated.

This time, Zhang Yanhang acquired a total of eighty Attack Speed Coin Fragments and ninety-four Speed Coin Fragments.

The reason for the uneven split is that Zhang Yanhang calculated that opening eighty-seven Attack Speed Coins and eighty-seven Speed Coins each, due to all the Kulunzo Magnetic Energy Heavy Tanks being cleared out in the Umbrella Biochemical Test Field, would mean neither is likely to form a new coin.

Since that's the case, it's better to focus on first completing a Speed Coin, then an Attack Speed Coin, keeping hope alive.

After the last Treasure Box, Zhang Yanhang still had five Attack Speed Coin Fragments and five Speed Coin Fragments. Altogether, he now had eighty-five Attack Speed Coin Fragments and ninety-nine Speed Coin Fragments.

"Unexpectedly, just one more Speed Coin Fragment is needed to create a new Speed Coin, but fortunately, it's not a major issue."

Zhang Yanhang planned to clean up the Umbrella Biochemical Test Field's Lucky Slot Machine later. Even with a small number of monsters in the third-place prize pool, getting a Speed Coin Fragment should not be problematic, ensuring a successful synthesis later.

After counting, Zhang Yanhang quickly synthesized the Attack Speed Coins and Speed Coins, forming four each, totaling six Attack Speed Coins and six Speed Coins in hand.

If lucky, with enough Kulunzo Magnetic Energy Heavy Tanks in the Lucky Slot Machine prize pool, he might expand to seven Attack Speed Coins and seven Speed Coins.

Meanwhile, Zhang Yanhang still held five Attack Speed Coin Fragments and nineteen Speed Coin Fragments, collectively needing sixteen more fragments. Calculating two fragments per Drop Treasure Box, he needed roughly eight more Drop Treasure Boxes.

If it's just eight Drop Treasure Boxes, replaying the Lucky Slot Machine's third-place pool a few times should patch it up. Even if not collecting enough Attack Speed Coins, Speed Coins are sure to be completed without concern.

"Sigh, ultimately, it's my Talent Level's upgrade being too slow. If my Luck Value had increased a bit earlier, I wouldn't have to worry about not having enough Coin Fragments now."

Granted, Zhang Yanhang felt the more pressing issue was the low set number of monsters in the Umbrella Biochemical Test Field. More monsters, even just an additional 10,000 to make it 100,000, would significantly improve the situation.

Sadly, the set number represents the rules of the Ashen World, something he couldn't manipulate. Otherwise, he'd promptly opt for tenfold refresh, super high drop rates, freeplay, true siege attack.

"One Speed Coin can boost Movement Speed by 57.5%, and four combined provide a 230% Movement Speed Bonus, almost matching my Ocean Rhythm Talent. Despite the Kulunzo Magnetic Energy Heavy Tanks being truly trashy, their drop items are the best.

Similarly, an Attack Speed Coin with the same Amplification Rate provides a 230% Attack Speed Bonus."

At present, solely the six Attack Speed Coins and six Speed Coins yield an amazing 345% bonus to Zhang Yanhang's Movement Speed and Attack Speed. If he can synthesize one more of each, it'd top over 400%.

"Admittedly, when Coin Equipment like these infinitely stackable Amulet types become wholesale, the resultant bonuses are indeed terrifying."

In terms of growth, Zhang Yanhang's twelve Coin Equipment currently offer more bonus than the Life Ring, Neck Potential Activation Device, and Electromagnetic Energy Pump combined, as this comprises twelve Orange Quality Equipment, all full-score.

Whereas other gear requires Zhang Yanhang to painstakingly fuse and break limits, Coin Equipment needs only simple synthesis, wasting perhaps a second, proving time- and energy-saving with an explosive cost-effectiveness.

"If I could somehow get a hundred Attack Speed Coins and Movement Speed Coins, I reckon I could punch a Seventh Tier Monster to death."

And according to the information Zhang Yanhang previously obtained from the group leader, the Sixth Tier is the True God, and the Seventh Tier would likely be deities of the level like the Moon Goddess and Storm God.

But unfortunately, a hundred coins remain a mere fantasy, as even slaughtering the entire Umbrella Biochemical Test Field only yielded six coins, and a hundred coins would need at least seventeen more Umbrella Biochemical Test Fields to be gathered.

After placing these four Attack Speed Coins and four Movement Speed Coins into his Waist Bag, Zhang Yanhang immediately conducted a simple test of his Movement Speed.

After the test, Zhang Yanhang found that his Movement Speed had indeed increased significantly. If his original speed was merely 6038 meters per second, it had now surged to 8438 meters per second, an increase of a substantial 2400 meters per second.

"If converted to the speed of sound, my current movement speed has increased from the original 17.8 Mach to 24.8 Mach, a rise of 7 Mach. This increase is truly remarkable, but after all, it is Coin Equipment, so being exaggerated is the most normal performance."

Before Zhang Yanhang's promotion, his fastest Movement Speed was merely 2.8 Mach, but now, just with four Movement Speed Coins, he had increased his total speed by 2.5 times that of the Fourth Tier Period.

It's worth noting that even if Zhang Yanhang maxed out his Agility attribute during his advancement, it only increased his Movement Speed by 11 Mach, but now just four Movement Speed Coins were equivalent to two-thirds of a tier advancement.

Moreover, these are just four Movement Speed Coins. Including the previous two Movement Speed Coins that increased by 3.5 Mach, these six Movement Speed Coins had already provided Zhang Yanhang with a total of 10.5 Mach of Movement Speed Bonus, already equivalent to one tier advancement.

In fact, Zhang Yanhang planned to gather another Movement Speed Coin. At that point, the bonus from the Movement Speed Coins alone would exceed the Movement Speed increase from a tier advancement combined with a fully maxed Agility attribute, which is quite outrageous.

But precisely because the Coin Equipment has such an exaggerated amplification effect, Zhang Yanhang had always been eager to acquire new Coin Equipment, but now that he had them in hand, he felt that he might have underestimated Coin Equipment.

"I previously set a modest goal of achieving a speed of Mach 20 in normal conditions. Now, let alone Mach 20, once I gather another new Movement Speed Coin, I'll easily surpass Mach 25 and approach Mach 30."

If Zhang Yanhang further applied Spiritual Energy, his Movement Speed would double again, reaching a staggering 49.6 Mach.

Such a level of Movement Speed far surpasses what can be described as an Intercontinental Ballistic Missile and even exceeds the speed of the Cosmic Flying Device, the Voyager 1, that he always wanted to surpass, since the fastest the Voyager 1 got was 49 Mach. Now, Zhang Yanhang is faster by 0.6 Mach.

So, the question arises, if Zhang Yanhang heads from Earth at point A, how long will it take to catch up with the Voyager 1, located 24 billion kilometers away from Earth at point B, and retrieve the Golden Record inside it?

Well, that's not important; he doesn't have the time for that sort of thing.

"I always felt that I could surpass the Voyager 1 before advancing to a higher tier, and now it seems that's indeed an easy feat."

Zhang Yanhang had previously estimated the effects of the Movement Speed Coins, so he had great confidence, and the actual situation indeed confirmed his expectations.

"As for my current Movement Speed after applying Spiritual Energy, if converted into meters, it reaches 16876 meters per second, which is approximately equivalent to moving 16.9 kilometers per second."

The small goal Zhang Yanhang set last time, which was achieving the Third Cosmic Speed, was only 16.7 kilometers per second, and he is now 0.2 kilometers per second faster than the Third Cosmic Speed. Therefore, if Zhang Yanhang wanted, he could easily escape the gravitational pull of the Solar System and embark on interstellar travel to other galaxies.

However, considering that other galaxies probably don't have Transmission Channels of the Ashen World, Zhang Yanhang felt it was better to stay on Earth and continue developing slowly.

Perhaps after he retires and has nothing else to do, he could visit other galaxies and have some fun with aliens, especially those that align with Earth people's aesthetics. Hmm, since there's reproductive isolation, he could probably have carefree fun, but he must be cautious of his enhanced reproductive capabilities, which might unexpectedly break through the reproductive barriers. He wouldn't want to turn into Emperor Biefeng.

"Having sequentially achieved the First Cosmic Speed, Second Cosmic Speed, and Third Cosmic Speed, perhaps next, I can start aiming for the Fourth Cosmic Speed."

Indeed, the Third Cosmic Speed is nowhere near the limit; beyond it lies the higher Fourth Cosmic Speed.

According to Zhang Yanhang's knowledge of physics, the first three stages are merely about escaping Earth's gravity, escaping celestial gravitational forces, and escaping the Solar System's gravitation. But the Fourth Cosmic Speed's goal is undoubtedly grander, as its target is to escape the Milky Way's gravitational force.

It's well-known that the Solar System is constantly in motion, dragging planets like Earth, Saturn, and Jupiter within the Milky Way's eight major planets along in a spiral surge, continually progressing, repeating cycles, with a two-hundred-million-year orbit around the Milky Way.

In some sense, escaping the Solar System's gravitational pull implies that even standing still would gradually distance one from the Solar System.

To draw a somewhat inadequate analogy, Zhang Yanhang escaping the Solar System's gravitational pull is like jumping off a moving high-speed train and flying up to run faster alongside the Solar System using his legs, while all the train crew would pile on to stop him from getting off.

Similarly, the Milky Way is also in motion, so due to much larger gravitational forces, if Zhang Yanhang cannot escape the gravitational pull of the Milky Way, he will eventually, like the Solar System, begin moving cyclically around the Milky Way, and it would be an unconscious motion, as all surrounding galaxies are also changing correspondingly.

Hence, escaping this environment requires a minimum movement speed of 120 kilometers per second, which Zhang Yanhang previously mentioned as the Fourth Cosmic Speed.
