Tower Defense Monster? I Am an Immortal Cultivator and Attack with Dimensionality Reduction

There are terrifying monsters in this world that are killing humans. After everyone reaches the age of eighteen, they will be assigned to the monster battlefield. Use technological defense towers and biological hormones to defend one side. The strong man is comparable to Superman, and the defense tower is comparable to alien technology. Weak people can also use hormones to gain unlimited strength in a short period of time. Ma Tian originally had weak tower defense, but unexpectedly gained the ability to travel through the fantasy world. And it was discovered that the monsters that invaded the earth turned out to be ferocious beasts that had been extinct for 100,000 years in the fantasy world. The flesh and blood of these ferocious beasts are all body-refining elixir formulas that have been lost for hundreds of thousands of years. Tower Defense: Tech defense tower? Sorry, I have the Purgatory Juesha Formation and the Trapped God Magic Heaven Formation. Laser cannon mechanical armor? Have you ever seen a spiritual weapon? Thousands of swords return to the sect, and soul-calming banners. Biohormones? Do you know what sanctification of the body is? Fantasy world: How come Ma Tian cultivates so fast? What? Is he practicing body training? Physical cultivation that has been lost for 100,000 years? This novel and its characters are purely fictitious.
