For the next thirty days, Lehman and Dehka lived a tense and dull life. Dehka pulled the tunnel bug that had finally hatched and his subordinates desperately began to dig the pit.

They first dug out five huge explosive storage rooms near the base of Dehaka. In these five huge storage rooms, they began to continuously store high-explosive crystals produced by the split bodies of the Sergeant Wolf - by the way, the Sergeant Wolf was forced to all be improved into drill bit-shaped crystals.

At the same time, the Sword Wolf and the Schizophrenic were constantly responsible for cutting down trees and strengthening the structure of the underground warehouse.

Just as Dehka began to dig an ultra-long tunnel of 38 kilometers and Shilang was desperately producing about 200 tons of high explosives, Lehman personally led Gangxian to start harassing and inducing Black - Lehman personally served as the beacon to guide the over-visual range attack, and Gangxian began to continuously launch missiles at Brack's camp for long-range bombing.

In this annoying harassment battle, Brack began to send his few flight troops to fight those missiles. When these flying Zergs, which are similar to flying dragons, Lehman will suddenly attack from the side, kill the insects in the air with a wave of shadow rage, and then run away.

In anger, Brack organized many encirclement and suppression troops, but Lehman, who had all escaped into the void, fled. In the end, the encirclement and suppression operations were forced to stop. However, if Lehman did not encircle Lehman, the air force would not be able to take off smoothly. Brack, who was constantly bombing the peripheral buildings by missiles, finally began to concentrate many buildings and troops as designed by Lehman, so as to use a large number of acid shells to concentrate fire and air defense.

It was not that Brack had thought of fighting back, but after seeing Lehman's last combat method, Brack had a resistance to attack Lehman's stronghold. In his opinion, Lehman, who has lost the key plant to produce explosives, can harass him like this, which is not enough.

Moreover, as centralized air defense is getting better and better, Brack's losses are getting less and less, and this big bug with limited IQ is not thinking about it anymore.

Just when Brack was driven away and harassed by Lehman and Gangxian, Knight would grab the high-explosion crystals produced by the splitting bodies of the Sword Wolf every day, and then repeatedly possessed Best, diving attacks at Yagdora's stronghold. The high-explosion crystals and plasma balls took turns to make the normal production and life of Yagdora's stronghold a mess. The insects had no choice but to be able to get a flexible Knight. Sometimes, only Yagdora could spray himself to drive away Knight.

This made Yagdra, the big digging worm, remained blind to the ongoing tunnel operations in Dehaka.

In fact, Yagdra and Brak were not completely unaware of Dehaka's tunnel operations, but Nairodra followed Lehman's advice and kept sending a small number of troops to conduct a large number of shallow digging operations to create crazily tricks, which made Brak and Yagdra not discover the real tunnel that Dehaka is located more than 30 meters underground.

By the end of 30 days, most of the tunnel operations in Dehaka had been completed, drainage work for underground radioactive materials rivers was completed, and a large number of explosion chambers were excavated:

The explosion chamber named [Sheer] by Lehman is 30 meters deep and stores a total of 15 tons of high-explosion crystals;

The explosion chamber named [Louise] by Lehman is 27 meters deep and stores a total of 10 tons of high-explosion crystals;

The explosion chamber named [Huihui] by Lehman is 25 meters deep and stores a total of 8 tons of high-explosion crystals;

There are 18 explosion chambers named in various styles above by Lehman. The amount of explosives is burial according to the explosion needs. The largest explosion chamber named "Jedha" by Lehman was stuffed with a total of 50 tons of high-explosion crystals - because this explosion chamber is responsible for destroying the nest plants that are inhabited by Blake Air Force flying insects.

After all the explosion chambers were arranged, Shilang arranged a split body in each explosion chamber. After receiving the signal, these split bodies will turn into dog meat detonators to detonate the explosion chambers.

Everything was ready, only the east wind was not there. One day when dawn was approaching, Lehman jumped on Knight's back, soared into the air again, flew over Black's camp for the final reconnaissance, and at the same time guided Gangxian to launch missiles and bomb Black's camp frantically. Knight himself also dived downwards and frantically.

Brack's troops were already air defense syndrome by explosives flying from high altitudes this month. As soon as the flames of Gangxian's biological missile thruster lit up in the dark, the entire stronghold immediately entered the air defense formation--the army building quickly closed, and countless Zergs that could spray acid balls at the air began to shoot the air---even the missile was finally destroyed, and Knight stopped diving and flew away.

Brack was a little proud while being irritated. He was very happy that he had stopped the opponent's attack again. The Zerg was tireless, so he was not tired, but it was always a problem, so Brack wanted to plan a large encirclement and completely eliminate Lehman.

Just as he was thinking this way, Lehman issued an order to detonate, and the high explosives from 18 explosion chambers were instantly detonated!

The ground cracked, and plants and soil rushed to the sky. The earth of Yiros trembled, and the pillars of fire rising into the sky were higher than those of Black. The night sky was illuminated by the pale fire that suddenly rose up during the day. Lehman and Knight were shaken in the air by the explosion. The explosion was so strong that Zelwin, who had been sleeping a lot of sleep a few dozen kilometers away, was awakened, thinking that an earthquake had occurred.

Many Brack's troops were directly killed or even torn apart by the violent explosion, but most of the Zergs survived under the violent shock wave, but these Zergs soon discovered that something really terrifying happened - the explosion spots arranged by Lehman made the scorching radioactive magma spray out from the densest places in Brack's troops!

The hot radioactive magma, like the melting of the core, is close to 3,000 degrees, and it has strong radioactive damage. After these devastating substances are sprayed out from under Black's stronghold, almost no Zerg troops can resist the damage of radioactivity and high temperatures at the same time. The evolutionary mechanism in their bodies cannot be reflected - the strong radio energy damages their organs. When these native Zergs are desperately urging evolution to fight these radioactivity, the high temperature begins to burn their bodies again.

Their evolution is not unlimited and time-consuming. Evolution requires time and substance. Under the double damage of high temperature and radioactive substances, Brack's troops began to disappear in pieces into scorching and wailing.

Looking at the tragic situation of his tribe, Brack desperately gathered his troops to escape to retreat to the highlands that had not been eroded by radiation magma, while roaring violently.

Looking at this tragic situation and the results of his hard work for a month, Dehaka looked at Lehman deeply-he felt that he had a new understanding of the race of human beings. Even if this race does not have the evolutionary ability of the Zerg, with these destructive knowledge in their heads, they are not opponents that can be underestimated.

If there is a chance, Dehaka feels that he must devour some human evolution and deepen his understanding of humans. Perhaps the evolution of these human thinking centers will be a good choice - Dehaka thought so.

Knight, who was standing by, also looked at Lehman, who created this tragedy for Brack's tribe. She was not a Virgin and had no feelings about the so-called "disappearance of life" - after all, all her races have disappeared in time, and her twin brother is still trying to destroy the universe.

Knight was surprised by Lehman's decisiveness, which made her a little more curious about the human soul that Lehman mentioned before - would such a soul full of two contradictory qualities, such as possibility and destruction, be the key to stop her brother?

However, while Knight was thinking, Lehman faced the remnants of Brack who had retreated towards them, lit up his light knife, and raised his arms and shouted loudly under the sunset:

"The enemy is coming up, raise your claws, and I will take you to attack!!!"
