Hearing Ji Changqing's words, Bigan smiled bitterly: "Of course it's my own heart, it's really not good, just find some beasts, you can't harm others because of me!"

The corners of Ji Changqing's mouth raised slightly, this guy is naturally kind-hearted.

In fact, there is no need for the other party to speak, Ji Changqing has already thought of something alternative for him.

Since Bigan has the intention of surrendering to him, then he can completely clone a heart from Bigan's cells.

Thinking of this, he put Bigan to sleep.

After that, he borrowed the power of the Invincible Dao Domain to speed up the time flow of the test frame next to him.

The heart that originally took countless days and nights to cultivate, Ji Changqing took less than half an hour to make it.

This heart is exactly the same as the Qiqiao Linglong Heart before Bigan, and after being conceived and nurtured by Ji Changqing's immortal power, it has obtained a trace of immortal power, which is enough to make Bigan glow stronger vitality.

When he put that heart back into his chest, he immediately activated the law of life and enveloped him.

In his opinion, Bigan's life is not illegal, and it can completely bring out the invincible Dao domain, so he is not worried that Bigan will return to his previous heartless appearance after leaving the invincible dao domain.

Half an hour later, the wound on Bigan's chest had healed completely.

And Bigan's hair had also turned black at this time, as if he was more than twenty years younger, the immortal qi in his body was slowly circulating, and his physical body had also returned to its best state.

Anyway, the other party wants to help him deal with things, and a strong man is always more energetic than an old man.

This can also be regarded as a gift from Ji Changqing to Bigan, provided that the other party must join his command later.

When Ji Changqing withdrew the Invincible Dao Domain, wisps of merit power suddenly descended from the sky.

This made Ji Changqing feel happy in his heart, and it seemed that there was an additional gain from this.

Those meritorious powers entered his sea of consciousness, and gradually condensed in one place, converging with the meritorious powers he had obtained before.

"Ding, the host has successfully transplanted the cloned heart for Bigan, accelerating the progress of civilization in this world, and doubling the expansion of the invincible Dao domain!"

"Ding, the host will spread the medical civilization as soon as possible, otherwise the invincible Dao domain will retract!"

The sound of the system rang out quickly.

After hearing the latter sentence, the smile that had just appeared on Ji Changqing's face couldn't help but dissipate.

His eyes swept over the medical equipment around him, and he realized that it might not be so easy to get the people of this era to grasp these things.

So he made books that could make anesthetics, as well as some advanced medical knowledge, and recorded all of them in one book.

After doing this, he called San Yisheng over and handed the book to the other party.

San Yisheng flipped through a few pages very curiously, and then his face showed a strong look of joy, and he said loudly to Ji Changqing: "King, if I have this book, why should I Xiqi be afraid of illness!"

Ji Changqing said with a smile: "This book ordered people to bring back to Xiqi, select professors who are loyal to this king, and then set up a Tai Hospital, train doctors, and assign them to my Xiqi territory or the army to save the dead and help the wounded!"

"The king is merciful!" San Yisheng complimented loudly.

Then he looked at Bigan who was lying on the operation sky, and said to Ji Changqing: "King, this person may be used by me Xiqi?"

Ji Changqing nodded slightly: "I have already given him a new life, when he wakes up, you will take him to meet Huang Feihu, so that they can familiarize themselves with the newborn things of my Xiqi army!"

He planned to focus on cultivating Bigan, but before that, it was necessary for Huang Feihu to have a good chat with him to deepen Bigan's disappointment with Yin Shang.

In this way, it won't be long before Bigan will take the initiative to come to him.

Ji Changqing explained a few more words to San Yisheng, and asked San Yisheng to wait here for Bigan to wake up.

He left the room and headed towards the arena.

Kong Xuan, the nine-headed black dragon, and Wu Wenhua followed behind him.

Soon, Shen Gongbao also led the white-fronted black-spotted tiger to run over, and saluted Ji Changqing with a smile.

Looking at this guy's appearance, Ji Changqing knew that San Yisheng's punishment was very light.

Shen Gongbao found that Ji Changqing was looking at him, and hurriedly smiled: "Master, are you planning to practice spells?"

Ji Changqing shook his head: "Spells are personal power after all, what I have to think about now is the entire Xiqi!"

And now that his Invincible Dao Domain has expanded to sixteen meters, this range is enough to make more large weapons.

He decided to create some equipment that would increase the combat effectiveness of the Xiqi army.

Among the planes, tanks, and artillery in the 21st world, Ji Changqing felt that the plane would take some time, and it was a little troublesome for the tank to move, but the cannon did not have too many restrictions.

Moreover, Ji Changqing is already planning to find an opportunity to create an air defense missile system for Xiqi.

When the time comes, if an immortal flies by, once it is locked, it will be directly bombarded with missiles.

As long as he bombarded it a few times, he didn't believe that anyone would dare to fly over the Xiqi army easily.

Now that he saw Shen Gongbao, he suddenly had an idea in his heart.

So he smiled at Shen Gongbao and said, "When this king makes some weapons that mortals can use, you and Xiao Jiu will help me try the power!"

Shen Gongbao didn't understand what Ji Changqing meant, and thought that he was letting them control the treasure.

So he immediately smiled and said: "Master don't worry, as long as you can use my affairs, you can just say it, I will definitely do it!"

With these words, Ji Changqing had already thought of the scene of this guy begging for mercy.

Smiling at Shen Gongbao, Ji Changqing waved his hands and completely opened the Invincible Dao Domain.

Immediately after that, his mind moved, causing a layer of black mist to envelop the Invincible Dao Domain.

At the same time, he transmitted the message to Huang Feihu, the commander of the artillery battalion, and asked him to take the people of the artillery battalion to the martial arts arena to assemble.

Soon, Ji Changqing used the power of the Invincible Dao Domain to create a heavy artillery.

After the black fog dissipated, Ji Changqing commanded the nine-headed black dragon, "Pull it away!"

The nine-headed black dragon immediately burst out laughing, and its body flew up rapidly, bringing the nearly three-ton 122-mm towed gun with it.

After that, he placed the artillery on the wall of Jiepai Pass, which can be regarded as saving Huang Feihu's artillery battalion a lot of effort.

Soon, Ji Changqing produced a hundred 122-mm towed guns.

He only left twenty gates in the Jiepai Pass, and then all the remaining ones were going to be sent back to Xiqi City.

With these cannons, he believed that Xiqi City would become impregnable.

Subsequently, Ji Changqing again manufactured a batch of W1987 Type 81mm mortars.

He asked Wang Zhao, the captain of the original artillery team and the current deputy commander of the artillery battalion, to select a group of elites.

For the time being, the men were in groups of ten, each receiving a mortar.

The order that Ji Changqing gave them was very simple, that is, to master the structure of these cannons as quickly as possible, and once he gave the order, he had to complete the firing as quickly as possible.
