Before the discovery at the deep pit of Qian Gu Mountain, the local weapons expert Tang Pin had achieved a major breakthrough in research:
That is the artificial synthesis of helium-iron microcrystals, replicating part of the effects of the barrier crystal array in the Mo family's chamber.
This barrier crystal array composed of helium-iron microcrystals is currently the greatest trump card for rabbits to counter the Nascent Soul Realm in individual combat.
Even super-energy rays exceeding 70TeV cannot physically break the barrier of the crystal array.
Considering this concept is relatively niche, here's a brief science popularization on what TeV really means.
The energy unit commonly used in fusion is MeV, and the numbers preceding are generally not large.
The photon released from the proton chain reaction occurring in the sun is about 5MeV at its peak.
And 1TeV equals 10 to the sixth power of MeV.
In other words.
5MeV and 70TeV differ by seven orders of magnitude.
