You're sick of feeling numb
You're not the only one
I'll take you by the hand
And I'll show you a world that you can understand
This life is filled with hurt
When happiness doesn't work
Trust me, and take my hand
When the lights go out you'll understand

I have done my research-nya.

|Process of Piercing the Chest to Reach the Heart​

This guide outlines the physical and biological steps required to pierce a human chest with bare hands to reach and manipulate the heart. All steps assume the absence of psychological, moral, or ethical considerations, focusing solely on the mechanical and biological feasibility.

Step 1: Breaching the Skin​

  • Anatomy: Human skin consists of the epidermis (~0.1-1.5 mm thick) and dermis (~1-4 mm thick), with a tensile strength of ~20-30 MPa. It is elastic but can be torn with sufficient force.
  • Process:
    • Use sharp, reinforced fingernails or claw-like structures to focus force on a small area (e.g., 1-2 cm²) over the chest, ideally between ribs 4 and 5 (left side, near the heart).
    • Apply a scratching or gouging motion with a force of ~100-200 N (equivalent to a strong pinch or clawing action). Repeated, rapid motions (10-20 scratches) can tear through the epidermis and dermis, creating a ragged wound ~2-5 cm wide.
    • Blood loss begins immediately, with superficial vessels (e.g., dermal capillaries) leaking ~10-20 mL of blood per minute.
  • Minimal Requirements:
    • Fingernails sharpened to a point (e.g., 0.5-1 mm tip) or supernaturally hardened to mimic animal claws (tensile strength ~100 MPa, comparable to keratin in predator claws).
    • Grip strength of ~200 N, achievable by a strong human but enhanced to ~500 N for efficiency in a fictional context.

Step 2: Tearing Through Subcutaneous Fat and Muscle​

  • Anatomy: Beneath the skin lies subcutaneous fat (~1-2 cm thick, low tensile strength of ~0.1 MPa) and the pectoralis major muscle (~1-3 cm thick, tensile strength ~0.1-0.5 MPa). These tissues are fibrous and resist tearing.
  • Process:
    • Dig fingers into the skin wound, hooking and pulling to separate fat layers. Fat is soft and yields easily, requiring ~50-100 N of force to tear.
    • Reach the pectoralis major muscle, which is denser. Use a clawing motion to shred muscle fibers, applying ~500-1,000 N of force (equivalent to a very strong grip or repeated tearing). Focus on a small area to minimize resistance.
    • Expect significant blood loss (~50-100 mL/min) from muscle vasculature (e.g., branches of the thoracoacromial artery). Muscle tissue will feel tough and stringy, requiring 1-2 minutes of sustained effort to create a ~5-10 cm deep cavity.
  • Minimal Requirements:
    • Grip strength of ~500-1,000 N to tear muscle efficiently. Normal human grip strength (~300-500 N for strong individuals) is insufficient for quick progress, so supernatural enhancement is needed.
    • Hands must be durable to avoid fractures or lacerations from repetitive force against fibrous tissue.

Step 3: Exposing the Ribs​

  • Anatomy: The rib cage (ribs 1-12, sternum, costal cartilage) protects the thoracic cavity. Ribs 4-6 (near the heart) are ~1 cm thick, with cortical bone (compressive strength ~170-190 MPa, tensile strength ~100-130 MPa). The periosteum (a thin connective tissue layer) covers the ribs, with low tensile strength (~0.1 MPa).
  • Process:
    • After tearing through ~3-5 cm of skin, fat, and muscle, the ribs are exposed. Scrape away the periosteum with fingers or nails (~50-100 N force) to reveal the bone surface.
    • Blood and tissue fluids (~100-200 mL total) will pool in the wound, obscuring visibility unless cleared (e.g., by wiping or supernatural means).
  • Minimal Requirements:
    • No additional force beyond what’s needed for muscle tearing. A small, focused wound (5-10 cm wide) between ribs 4 and 5 provides access to the rib cage.

Step 4: Breaking or Separating the Ribs​

  • Anatomy: Ribs are anchored to the sternum (via costal cartilage) and spine, forming a rigid cage. Breaking a rib requires ~1,000-1,500 N of force, while separating ribs (prying them apart) requires ~2,000-3,000 N due to cartilage and ligament resistance.
  • Process:
    • Breaking Ribs (Preferred Method):
      • Grip a single rib (e.g., rib 5) with both hands, applying a twisting or snapping force (~1,000 N) to fracture it. Focus on the midsection, where ribs are less curved and more prone to breaking.
      • A single fracture creates a ~1-2 cm gap, sufficient to access the thoracic cavity. Breaking two ribs (e.g., ribs 4 and 5) widens the gap to ~5-10 cm.
      • Expect a sharp cracking sound and bone fragments, which may cut surrounding tissue or the attacker’s hands unless protected.
    • Separating Ribs (Less Feasible):
      • Insert fingers into the intercostal space and pull ribs apart in opposite directions. This requires ~2,000-3,000 N due to the elasticity of costal cartilage (~10-20 MPa tensile strength).
      • Separation is slower and more energy-intensive, as cartilage stretches before tearing. A ~5-10 cm gap requires sustained pulling for 10-20 seconds.
    • Blood loss escalates (~200-300 mL/min) from intercostal arteries, and the victim may enter shock (though ignored for fictional purposes).
  • Minimal Requirements:
    • Grip strength of ~1,000 N for breaking ribs or ~3,000 N for separating them. Normal humans cannot achieve this, requiring supernatural strength.
    • Hands must withstand bone fragments and friction (e.g., via hardened skin or magical protection).

Step 5: Accessing the Thoracic Cavity​

  • Anatomy: The heart lies in the mediastinum, behind the sternum and between ribs 2-6, encased in the pericardium (a fibrous sac, tensile strength ~2-5 MPa). The lungs and pleura (thin membranes) surround it, with minimal resistance (~0.1 MPa).
  • Process:
    • After breaking or separating ribs, push through the pleura (~50 N force) to enter the thoracic cavity. The lungs may collapse due to air exposure (pneumothorax), but this is irrelevant for the goal.
    • Locate the pericardium, a tough, leathery sac ~1-2 mm thick. Tear it open with fingers (~100-200 N force) to expose the heart, a muscular organ (~300-400 g, ~10 cm long).
    • Blood loss intensifies (~500-1,000 mL/min) from major vessels (e.g., internal thoracic artery), filling the cavity with blood.
  • Minimal Requirements:
    • Moderate force (~100-200 N) to tear the pericardium, achievable with enhanced grip strength. No additional tools needed once ribs are bypassed.

Step 6: Piercing or Crushing the Heart​

  • Anatomy: The heart is a muscular organ with a tensile strength of ~0.1-0.5 MPa (similar to skeletal muscle). Crushing it requires compressing its chambers (ventricles and atria), which are filled with ~100-200 mL of blood, against its fibrous structure.
  • Process:
    • Piercing: Insert fingers into the heart muscle, targeting the left ventricle (thickest wall, ~1-1.5 cm). Apply ~500-1,000 N to penetrate and tear the muscle, creating a hole. Blood will gush out (~1,000 mL/min), as the heart pumps ~5-6 L/min at rest.
    • Crushing: Grip the heart with both hands and squeeze with ~1,000-2,000 N to collapse its chambers. This disrupts blood flow, causing immediate cardiac arrest. The heart feels firm and slippery, requiring a strong grip to prevent slipping.
    • The process takes ~5-10 seconds, as the heart’s muscle resists compression until its fibers tear.
  • Minimal Requirements:
    • Grip strength of ~1,000-2,000 N to crush or pierce the heart. Normal human grip (~500 N max) is insufficient, requiring supernatural enhancement.
    • Hands must resist blood slickness and muscle resistance, ideally with enhanced friction or grip (e.g., claw-like fingers).

Total Time and Force Requirements​

  • Time: Without enhancements, the process takes ~5-10 minutes (1-2 min for skin, 2-3 min for muscle, 1-2 min for ribs, 1 min for pericardium and heart). With supernatural abilities, it could take seconds (e.g., 10-20 seconds total).
  • Force:
    • Skin: ~100-200 N
    • Muscle: ~500-1,000 N
    • Ribs (breaking): ~1,000-1,500 N
    • Ribs (separating): ~2,000-3,000 N
    • Pericardium: ~100-200 N
    • Heart (piercing/crushing): ~1,000-2,000 N
  • Total Blood Loss: ~1,000-2,000 mL over the process, leading to exsanguination within minutes.

It's bearable because I'm having 2010s nostalgia, when I had no phone at all. The only downside is that it's super dark when there's no moon when I'm in a field near my home, I can't see jack shit

Aren't you addicted to gacha games? I'd thought you'd be suffering more then what you're telling me... However good to see you're doing well except for the dark part, moonless nights are no joke you could step on anything there. Also when will you get you're phone or laptop back(I'm assuming you went for repairs or are you going to buy some new ones?).
