"And even if I move at 17,284 kilometers per hour, that's just my usual speed. If I activate the Spiritual Qi Blessing, I can move at 34,568 kilometers per hour.

The circumference of the Earth's equator is only 40,076 kilometers, so in about 70 minutes, just over an hour, I can circle the Earth, heading east and returning from the west, personally verifying the roundness of the Earth and returning to the starting point from another direction."

Before Zhang Yanhang's rank promotion, he needed seven hours to circle the equator, and now it's reduced to just over an hour, a very noticeable difference indeed.

Apart from that, before his promotion to the Fourth Tier, Zhang Yanhang also had a small dream of traveling the Earth in one hour, and now it's almost fulfilled, since he can circle the equator in just over an hour, faster than the Fast Dragon in Pokemon, which takes sixteen hours to circle the Earth, by more than tenfold.

"Not to mention the Earth; even if I want to go to the Moon, which is 400,000 kilometers away from the Earth, I can fly there in twelve hours, making a round trip in one day."

Zhang Yanhang indeed senses the outrageous level he has reached after advancing to the Fourth Tier. His strength isn't just a slight improvement but a true qualitative leap, stepping into a whole new, stronger level, distinctly different from his Third Tier period.

"With this level of speed, my hunting efficiency will definitely have a significant increase. The specific hunting efficiency will surely be astonishing..."

If it weren't for the Transmission Channel not open, Zhang Yanhang would love to go hunting monsters in the Ashen World right now.

After testing his speed, Zhang Yanhang began testing his strength. He first took out half of his steel stock from his Waist Bag and placed it on his right hand, but as expected, the 3,140 tons of steel felt far from his limit.

So, Zhang Yanhang put the remaining half of the 3,140 tons of steel on it, but surprisingly, it still felt far from his limit, with plenty of spare capacity.

But the problem was, all the steel Zhang Yanhang had smelted before had now been used up, so he had to activate Alchemy, using the island's materials to transform more steel cubes and continue stacking them on his hand. This time, he transformed over ten thousand tons, which should be about right.

After smelting, Zhang Yanhang placed another three thousand tons of steel on his hand, totaling ten thousand tons, but still felt plenty of spare capacity, so he added another two thousand tons of steel.

This time, it finally felt about right, although not entirely at the limit, the gap to the limit was quite small.

After gradually adding over three hundred more tons of steel, Zhang Yanhang finally tested his current strength, which turned out to be as high as 12,334 tons, similar to when he first advanced to the Third Tier and activated the Hundred Feet Dharma Body State.

"Before my rank promotion, my single-hand strength was only 1,053 tons, and now it's increased to 12,334 tons. That's an increase of 11,281 tons of strength, or eleven times the strength..."

At times like these, Zhang Yanhang couldn't help but sigh that rank promotion is indeed the best way to enhance one's strength.

"And with my current strength, if I add a bit of Spiritual Energy, I can immediately reach 24,668 tons. As for calculating double-handed strength, that's a staggering 61,670 tons.

I feel like I can fly carrying a ten thousand-ton giant wheel like Superman, but unfortunately, I don't have a biological field and can only use an Energy Shield to support it. Whether I can lift it without damaging the bottom of the ship is indeed a question."

Of course, if Zhang Yanhang is willing to consume energy, these little problems will all be resolved.

"And if calculated in jin, my current double-handed strength has reached an impressive 1.23 billion jin in the Mystical World..."

Calculating one jin of raw rice per person per day for Qin Island City's twenty million population, Zhang Yanhang can now lift enough rice to supply Qin Island City for six days. As for supplying the entire Empire's two billion population, he could supply a sixteenth of the population.

After a simple test, Zhang Yanhang turned around and, after imbued with Spiritual Qi, swung a fist towards the direction of the uninhabited Pacific Ocean.

With the deafening sound of an explosion, a massive Air Bomb slammed onto the originally calm sea surface, and with immense impact, millions of tons of seawater soared, splashing up to a hundred meters into the air.

A sea area spanning ten kilometers split dry like Moses parted the sea in myths, forming a giant sea bowl.

But the powerful impact continued downward, instantly fracturing the soil layer at the top of the dried sea bed and spreading outwards, revealing the hard gray-black basalt underneath.

But no matter how hard it is for ordinary people, in front of Zhang Yanhang, this basalt is no different from ordinary seawater.

Even though part of the impact force transformed into a seaquake and was about to cause a tsunami, the remaining impact force still had excellent effects when facing solid units like basalt.

The basalt shattered layer by layer, with fragments flying out like solid cannonballs, constantly bombarding the surrounding sea surface creating enormous tremors.

The giant Air Bomb dissipated only after penetrating more than two thousand meters of basalt, leaving a bottomless pit about eight or nine kilometers wide and over two thousand meters deep before Zhang Yanhang.

And this is still not the end. At the bottom of the pit, a faint red light appeared, and only a few seconds later, a massive magma beam erupted, carrying shattered surrounding basalt to form volcanic bombs one or two meters big, firing into the sea over dozens of kilometers.

The basalt volcanic bombs dropped into the sea slowly cooled, making sizzling sounds, generating large clouds of steam and thick black smoke as a result.

At this point, the previously scattered sea water around is gradually receding, but since the original sea bed was only one or two hundred meters deep, and now there's a two thousand meter deep sea floor pit blasted by Zhang Yanhang, the returning sea water could only fill a small part of it despite the receding.

As a result, sea water from other directions flowed into the undersea pit blasted by Zhang Yanhang, forming a huge deep-sea vortex in the process.

The seawater within the large whirlpool inevitably comes into contact with the underwater volcano and the magma that was punched out by Zhang Yanhang. Under the cooling effect of the seawater, this magma gradually turns from fiery red to gray-black.

Gradually solidifying and transforming into magma rock, it covers the originally ruined basalt fragments in the vicinity, beginning to form a new rock layer to repair the surrounding crust.

However, the underwater volcano, or rather the gap in the crust that was punched out, did not dissipate; instead, it appeared to intensify, with the magma eruption becoming even more fierce.

The surrounding seawater gradually boils due to heat conduction in the process of cooling the magma, starting to bubble, and simultaneously, a large amount of steam rises up with thick black smoke.

Upon encountering each other, the volcanic ash cloud immediately transforms into a black rain cloud, beginning to fall as gray-black ash rain over nearby sea areas, polluting the nearby sea currents.

Moreover, this gray-black ash rain is laced with toxic gases from the volcano, possessing strong corrosiveness and toxicity.

With the spread of toxicity and the rise in temperature, large numbers of belly-up sea fish, which like backstroke, start to float on the surface of the surrounding sea.

Unfortunately, due to the large amounts of sulfur and chlorine gases emitted from the volcano, the area is filled with a strong rotten egg smell mixed with a stinging odor like an uncleaned public school toilet for a week.

Otherwise, one might somewhat smell the scent of sea fish cooked by the seawater, after all, it is pure natural sea fish, born in the sea, cooked in the sea, and backstroking in the sea.

At this time, accompanying the conduction of shock waves, parts of the ocean currents are not being pulled into this deep-sea whirlpool. Instead, they form huge waves, dozens of meters high, surging upwards and expanding in all directions.

It is expected that if no accidents occur, this will subsequently form a giant tsunami and strike nearby coastal areas, for instance, South Korea, or Japan, for example.

As for Qin Island City behind him, there's no need to worry too much. After all, he was throwing the punch with his back facing Qin Island City, so the shock wave spreading in this direction is not very large. Furthermore, part of it was blocked by the deserted island under his feet, so it's alright, basically posing no threat.

Zhang Yanhang originally wanted to continue observing the subsequent changes, but unexpectedly, in a mere short moment, someone had already arrived.

According to his perception, an Awakener from the Empire was speeding toward this direction, prompting Zhang Yanhang to teleport himself at once, directly relocating to an uninhabited deserted island in the Indonesia Archipelago he passed by earlier.

He had no choice, to prevent unnecessary disputes, Zhang Yanhang could only slip away first.

Mainly because he had just recently been promoted in rank and wanted to test his strength, he was not consciously aware of his own strength, resulting in the punch leading to this effect, there was nothing he could do about it.

"I almost seem to have punched through the Earth's crust, no wonder they came to catch me so soon..."

Based on Zhang Yanhang's scan, the area he was just in, since it was part of the seabed, had a weaker crust, roughly only about six thousand meters. His punch directly penetrated halfway through, further igniting a magma eruption due to the fault line in the crust caused by the punch.

He figures if he really exerted more force, he could indeed punch through the crust directly.

After all, even before Zhang Yanhang's rank promotion, he could create a pit several hundred meters deep in the Fatian Xiangdi state on Crimson Iron Ore, which is at least ten times the strength of steel.

Now, since the seawater buffered the punch, merely penetrating over two thousand meters of the crust was actually exercising restraint.

After all, the punch was not exactly direct, it was merely an indirect air fist. If a solid punch were to be thrown, the crust would likely be penetrated directly, potentially reaching the mantle layer instantly.

Due to the Spiritual Qi Blessing, Zhang Yanhang's punch just now reached a force of nearly twenty-five thousand tons, with an Attack Speed reaching a terrifying fifty mach, double that of an Intercontinental Ballistic Missile.

He took out his phone and calculated with a kinetic energy formula. The final result was that his punch should have had at least 4548,2267,4780,6000J or 4548.2276 terajoules (trillion joules).

A ton of TNT explosion produces 41.84 billion joules of energy, therefore, according to actual calculations, even considering pure kinetic energy alone, his punch was equivalent to 108,7052 tons of TNT, commonly referenced as 108-kiloton yield.

"The yield of Little Boy was about 12.5 kilotons, so my punch was roughly equivalent to eighty-seven Little Boys."

According to the damage radius formula, a nuclear bomb with a yield of 108 kilotons should have a damage radius of about 7.11 kilometers, translating to a 159 square kilometer coverage range.

Furthermore, this calculation only involves pure force and speed, but due to numerous other bonuses I have, such as Attack Power Bonus, Physical Attack Power Bonus, Critical Strike Damage Bonus, Armor Penetration Bonus... and a series of related bonuses, the final outcome is only higher."

In this regard, Zhang Yanhang even feels that the scene earlier was still a bit small. If he truly punched with all his might, the damage radius would definitely be even greater, but the crust would completely collapse, so there's no need to make such a severe move. After all, there's only one Earth, spending more time in the Ashen World destroying it is better, breaking something there doesn't matter.

"But in any case, in summary, my current punch equals a nuclear bomb, even just a basic Normal Attack reinforced with Spiritual Qi equates to a strategic nuclear bomb of a hundred-kiloton yield, which is the largest yield among conventional nuclear weapons. Generally, nuclear weapons above a hundred-kiloton yield are only manufactured in small quantities."

The reason for limited production of large-yield weapons is mainly that their yield is too large for practical use. After all, although the damage radius may only be 7.11 kilometers, the meaning of the damage radius is that one cannot survive within that range.

In addition, there's a larger nuclear radiation range and shock wave spread range, even people outside the damage radius will suffer burn injuries due to extreme temperatures causing potential fatal effects. Without proper protective measures, at least playing around with an amputation can be mixed.

So, in practical situations, a single hundred-kiloton yield nuclear weapon is enough to destroy a small city. As for large cities, even a megaton won't suffice, so it's better to deploy several hundred-kiloton nuclear bombs, dispersing them to rely on shockwave range to kill enemies and destroy city structures more cost-effectively.
